@@ -36,272 +32,287 @@ CMake deals with three directories: source, build or binary and installation.
 The good practice is not to use the source directory as a build one.
 Different configurations should be built in different build directories to avoid conflicts. 
 It is however possible to choose one installation directory for several configurations of OCCT (differentiated by platform, bitness, compiler and build type), for example:
-      
-    d:/occt/                   -- the source directory
-    d:/tmp/occt-build-vc10-x64 -- the build directory with the generated

+
+**genproj** is a less flexible alternative to use of CMake build system (see @ref build_occt_win_cmake), but still has some small features useful for OCCT development.
+
+@subsection build_genproj Configuration process
+
+The environment is defined in the file *custom.sh* (on Linux and macOS) or *custom.bat* (on Windows) which can be edited directly:

+* `HAVE_*` -- flags to enable or disable use of optional third-party products
+* `CSF_OPT_*` -- paths to search for includes and binaries of all used  third-party products
+* `SHORTCUT_HEADERS` -- defines method for population of folder *inc* by header files. Supported methods are:

+AIS: Custom Presentation {#tutorials__ais_object}
+========
+
+@tableofcontents
+
+@section intro Getting Started
+
+OCCT provides a strong set of built-in Interactive Objects for rapid application development,
+but the real power and flexibility of **Application Interactive Services** (@c AIS) could be revealed by subclassing and implementing custom presentations.
+In this tutorial we will focus on the development of a custom @c AIS_InteractiveObject and show the basics step by step.
+
+Let's start from the very beginning and try subclassing @c AIS_InteractiveObject object:
+
+~~~~{.cpp}
+class MyAisObject : public AIS_InteractiveObject
+{
+  DEFINE_STANDARD_RTTI_INLINE(MyAisObject, AIS_InteractiveObject)
+public:
+  MyAisObject() {}
+public:
+  virtual void Compute (const Handle(PrsMgr_PresentationManager)& thePrsMgr,
+                        const Handle(Prs3d_Presentation)& thePrs,
+                        const Standard_Integer theMode) override {}
+
+  virtual void ComputeSelection (const Handle(SelectMgr_Selection)& theSel,
+                                 const Standard_Integer theMode) override {}
+
+  virtual bool AcceptDisplayMode (const Standard_Integer theMode) const override
+  { return true; }
+};
+~~~~
+
+@c DEFINE_STANDARD_RTTI_INLINE() macro will register the new class within the OCCT Run-Time Type Information (RTTI) system.
+This step is optional (you may skip it if you are not going to use methods like @c Standard_Transient::DynamicType() in application code), but it is a common practice while subclassing OCCT classes.
+
+The @c AIS_InteractiveObject interface defines only a couple of pure virtual methods - @c @::Compute() defining an object presentation and @c @::ComputeSelection() defining a selectable (pickable) volume.
+Selection and presentation are two independent mechanisms in **AIS**. Presentation rendering is done with help of OpenGL or a similar low-level graphics library, while selection doesn't depend on a graphic driver at all.
+Providing an empty implementation of these two methods would be enough for adding the object to @c AIS_InteractiveContext (@c @::Display()), but obviously nothing will appear on the screen.
+
+@section prs_builders Presentation builders
+
+To go ahead, we need to define some presentation of our object.
+OCCT provides a set of presentation building tools for common elements like arrows, shapes, boxes, etc.
+These tools could be found within @c Prs3d, @c StdPrs and @c DsgPrs packages:
+
+- **Prs3d**
+  provides builders for simple geometric elements.
+  - @c Prs3d_Arrow, @c Prs3d_BndBox, @c Prs3d_Point, @c Prs3d_Text, @c Prs3d_ToolCylinder, @c Prs3d_ToolDisk, @c Prs3d_ToolSector, @c Prs3d_ToolSphere, @c Prs3d_ToolTorus
+- **StdPrs**
+  provides builders for analytical geometry and B-Rep shapes (@c TopoDS_Shape).
+  - @c StdPrs_WFShape, @c StdPrs_ShadedShape, @c StdPrs_BRepTextBuilder
+- **DsgPrs**
+  provides builders for datums, dimensions and relations.
+
+Presentation builders are reusable bricks for constructing @c AIS objects.
+Standard OCCT interactive objects highly rely on them, so that you may easily replicate @c AIS_Shape presentation for displaying a shape with just a couple of lines calling @c StdPrs_ShadedShape:
+
+~~~~{.cpp}
+void MyAisObject::Compute (const Handle(PrsMgr_PresentationManager)& thePrsMgr,
+                           const Handle(Prs3d_Presentation)& thePrs,
+                           const Standard_Integer theMode)
+{
+  TopoDS_Shape aShape = BRepPrimAPI_MakeCylinder (100.0, 100.0);
+  StdPrs_ShadedShape::Add (thePrs, aShape, myDrawer);
+}
+...
+Handle(AIS_InteractiveContext) theCtx;
+Handle(MyAisObject) aPrs = new MyAisObject();
+theCtx->Display (aPrs, true);
+~~~~
+
+@figure{ais_object_step1_shaded.png,"@c StdPrs_ShadedShape presentation builder.",409} height=409px
+
+@c PrsMgr_PresentableObject::Compute() method takes three arguments:
+- **Presentation Manager** (@c PrsMgr_PresentationManager).
+  Rarely used parameter, but might be necessary for some advanced use cases.
+- **Presentation** (@c Prs3d_Presentation or @c Graphic3d_Structure).
+  Defines the structure to fill in with presentation elements.
+- **Display Mode** (integer number).
+  Specifies the display mode to compute.
+  **0** is a default display mode, if not overridden by @c AIS_InteractiveObject::SetDisplayMode() or by @c AIS_InteractiveContext::Display().
+
+For each supported display mode, the **Presentation Manager** creates a dedicated @c Prs3d_Presentation and stores it within the object itself as a list of presentations @c PrsMgr_PresentableObject::Presentations().
+It is a good practice to reject unsupported display modes within @c @::Compute() method:
+
+~~~~{.cpp}
+void MyAisObject::Compute (const Handle(PrsMgr_PresentationManager)& thePrsMgr,
+                           const Handle(Prs3d_Presentation)& thePrs,
+                           const Standard_Integer theMode)
+{
+  if (theMode != 0) { return; } // reject non-zero display modes
+
+  TopoDS_Shape aShape = BRepPrimAPI_MakeCylinder (100.0, 100.0);
+  StdPrs_ShadedShape::Add (thePrs, aShape, myDrawer);
+}
+~~~~
+
+This wouldn't, however, prevent application from displaying the object with another display mode like this:
+
+~~~~{.cpp}
+Handle(AIS_InteractiveContext) theCtx;
+Handle(MyAisObject) aPrs = new MyAisObject();
+theCtx->Display (aPrs, 100, -1, true);
+~~~~
+
+The code above will display @c MyAisObject with display mode equal to 100, and after @c @::Compute() modifications nothing will be displayed on the screen.
+@c AIS will still create a presentation with specified display mode, but it will be empty - method @c @::AcceptDisplayMode() could be overridden to disallow even creation of an empty presentation:
+
+~~~~{.cpp}
+bool MyAisObject::AcceptDisplayMode (const Standard_Integer theMode) const
+{
+  return theMode == 0; // reject non-zero display modes
+}
+~~~~
+
+@c AIS_InteractiveContext::Display() checks if requested display mode is actually supported by the object, and uses default display mode (_**0**_) if it is not.
+@c StdPrs_ShadedShape prepares a shaded (triangulated) presentation of a shape, while @c StdPrs_WFShape creates a wireframe presentation with B-Rep wire boundaries:
+
+~~~~{.cpp}
+void MyAisObject::Compute (const Handle(PrsMgr_PresentationManager)& thePrsMgr,
+                           const Handle(Prs3d_Presentation)& thePrs,
+                           const Standard_Integer theMode)
+{
+  if (!AcceptDisplayMode (theMode)) { return; }
+
+  TopoDS_Shape aShape = BRepPrimAPI_MakeCylinder (100.0, 100.0);
+  StdPrs_ShadedShape::Add (thePrs, aShape, myDrawer); // add shading
+  StdPrs_WFShape::Add     (thePrs, aShape, myDrawer); // add wireframe
+}
+~~~~
+
+@figure{ais_object_step1_shaded_wf.png,"Result of @c StdPrs_ShadedShape + @c StdPrs_WFShape presentation builders.",409} height=409px
+
+Presentation builders take the @c Prs3d_Drawer object defining various attributes - material of shaded shape, number of isolines in wireframe mode, tessellation quality, line colors and many others.
+@c PrsMgr_PresentableObject defines @c myDrawer property with default attributes.
+@c StdPrs makes it easy to display topological shapes.
+With the help of @c Prs3d tools we may display elements like arrows, boxes or text labels.
+Let's extend our presentation with a second **display mode 1** showing a bounding box using @c Prs3d_BndBox builder:
+
+~~~~{.cpp}
+bool MyAisObject::AcceptDisplayMode (const Standard_Integer theMode) const
+{
+  return theMode == 0 || theMode == 1;
+}
+void MyAisObject::Compute (const Handle(PrsMgr_PresentationManager)& thePrsMgr,
+                           const Handle(Prs3d_Presentation)& thePrs,
+                           const Standard_Integer theMode)
+{
+  TopoDS_Shape aShape = BRepPrimAPI_MakeCylinder (100.0, 100.0);
+  if (theMode == 0)
+  {
+    StdPrs_ShadedShape::Add (thePrs, aShape, myDrawer);
+    StdPrs_WFShape::Add (thePrs, aShape, myDrawer); // add wireframe
+  }
+  else if (theMode == 1)
+  {
+    Bnd_Box aBox;
+    BRepBndLib::Add (aShape, aBox);
+    Prs3d_BndBox::Add (thePrs, aBox, myDrawer);
+  }
+}
+~~~~
+
+Now, displaying an object with **display mode 1** will show a box:
+
+~~~~{.cpp}
+Handle(AIS_InteractiveContext) theCtx;
+Handle(MyAisObject) aPrs = new MyAisObject();
+theCtx->Display (aPrs, 1, 0, true);
+~~~~
+
+@figure{ais_object_step1_bndbox.png,"@c Prs3d_BndBox presentation builder.",409} height=409px
+
+@c AIS disallows activating multiple display modes at the same time, so that these presentation modes should be alternatives to each other.
+But @c AIS may use non-active display mode for highlighting purposes - like wireframe (@c AIS_Wireframe) presentation displayed on top of shaded (@c AIS_Shaded) presentation for selected @c AIS_Shape objects.
+
+Let's define a dedicated enumeration for display modes supported by our interactive object and setup the 1st (@c MyDispMode_Highlight) display mode for highlighting with help of @c PrsMgr_PresentableObject::SetHilightMode():
+
+~~~~{.cpp}
+class MyAisObject : public AIS_InteractiveObject
+{
+public:
+  enum MyDispMode { MyDispMode_Main = 0, MyDispMode_Highlight = 1 };
+
+...
+
+MyAisObject::MyAisObject()
+{
+  SetDisplayMode (MyDispMode_Main);      // main (active) display mode
+  SetHilightMode (MyDispMode_Highlight); // auxiliary (highlighting) mode
+}
+
+...
+
+Handle(AIS_InteractiveContext) theCtx;
+Handle(MyAisObject) aPrs = new MyAisObject();
+theCtx->Display (aPrs, MyAisObject::MyDispMode_Main, 0, false);
+theCtx->HilightWithColor (aPrs, aPrs->HilightAttributes(), false);
+theCtx->CurrentViewer()->Redraw();
+~~~~
+
+@figure{ais_object_step1_highlight.png,"Highlighting by color (left) and highlighting by another display mode (right).",818} height=409px
+
+In this particular use case we've used the method @c AIS_InteractiveContext::HilightWithColor() instead of @c @::SetSelected() - just because our object is not selectable yet and @c @::SetSelected() wouldn't work.
+Highlighted presentation appears on the screen with modulated color (see left screenshot above).
+Using a dedicated display mode for highlighting (right screenshot above) allows customizing presentation in selected / highlighted states.
+
+@section prim_arrays Primitive arrays
+
+@c Prs3d_Presentation might be filled in by the following **primitives**:
+- **Triangles**
+  - @c Graphic3d_ArrayOfTriangles
+  - @c Graphic3d_ArrayOfTriangleFans
+  - @c Graphic3d_ArrayOfTriangleStrips
+- **Lines**
+  - @c Graphic3d_ArrayOfSegments
+  - @c Graphic3d_ArrayOfPolylines
+- **Points** or **Markers**
+  - @c Graphic3d_ArrayOfPoints
+
+This triplet of primitives is what graphics hardware is capable of rendering, so that it could be transferred directly to low-level graphics libraries in the form of *Vertex Buffer Objects* (VBO).
+Each **primitive array** consists of an array of vertex attributes (_**position**, **normal**, **texture coordinates**, **vertex colors**_, etc.) and optional **array of indices**.
+The latter one avoids duplicating vertices shared between connected elements (triangles, polylines) in attributes array.
+
+@c Graphic3d_ArrayOfPrimitives and it's subclasses provide a convenient interface for filling in primitive arrays:
+- Constructor takes a number of vertices, number of edges (indices) and a bitmask of optional vertex attributes.
+- @c Graphic3d_ArrayOfPrimitives::AddVertex() appends a vertex with specified attributes to the end of the array (within the range specified at construction time).
+- @c Graphic3d_ArrayOfPrimitives::AddEdges() appends indices, starting with 1.
+  Each line segment is defined by two consequential edges, each triangle is defined by three consequential edges.
+
+Let's extend our sample and display a cylinder section contour defined by array of indexed segments (e.g. a polyline of four vertices):
+
+~~~~{.cpp}
+void MyAisObject::Compute (const Handle(PrsMgr_PresentationManager)& thePrsMgr,
+                           const Handle(Prs3d_Presentation)& thePrs,
+                           const Standard_Integer theMode)
+{
+  const double aRadius = 100.0, aHeight = 100.0;
+  TopoDS_Shape aShape = BRepPrimAPI_MakeCylinder (aRadius, aHeight);
+  if (theMode == MyDispMode_Main)
+  {
+    StdPrs_ShadedShape::Add (thePrs, aShape, myDrawer);
+    //StdPrs_WFShape::Add (thePrs, aShape, myDrawer);
+    Handle(Graphic3d_ArrayOfSegments) aSegs = new Graphic3d_ArrayOfSegments (4, 4 * 2, Graphic3d_ArrayFlags_None);
+    aSegs->AddVertex (gp_Pnt (0.0, -aRadius, 0.0));
+    aSegs->AddVertex (gp_Pnt (0.0, -aRadius, aHeight));
+    aSegs->AddVertex (gp_Pnt (0.0,  aRadius, aHeight));
+    aSegs->AddVertex (gp_Pnt (0.0,  aRadius, 0.0));
+    aSegs->AddEdges (1, 2);
+    aSegs->AddEdges (2, 3);
+    aSegs->AddEdges (3, 4);
+    aSegs->AddEdges (4, 1);
+    Handle(Graphic3d_Group) aGroupSegs = thePrs->NewGroup();
+    aGroupSegs->SetGroupPrimitivesAspect (myDrawer->WireAspect()->Aspect());
+    aGroupSegs->AddPrimitiveArray (aSegs);
+  }

+}
+~~~~
+
+@figure{ais_object_step2_segments.png,"Displaying @c Graphic3d_ArrayOfSegments.",409} height=409px
+
+The process is quite straightforward:
+- Create a new @c Graphic3d_Group using @c Prs3d_Presentation::NewGroup();
+- Specify presentation aspects using @c Graphic3d_Group::SetGroupPrimitivesAspect();
+- Create and add an array of primitives using @c Graphic3d_Group::AddPrimitiveArray().
+
+Standard presentation builders like @c StdPrs_ShadedShape / @c StdPrs_WFShape internally do exactly the same thing - a tessellated representation of a shape is added to presentation in form of triangles (shaded),
+line segments (wireframe and free edges) and markers (free shape vertices).
+
+A single @c Graphic3d_Group normally defines just a single primitive array, but it is technically possible adding more arrays to the same group @c Graphic3d_Group::AddPrimitiveArray()
+and with different aspects @c Graphic3d_Group::SetPrimitivesAspect(), which might be considered in advanced scenarios.
+
+Method @c Graphic3d_Group::AddText() allows adding text labels to a presentation.
+Internally, text labels are rendered as an array of textured triangles using texture atlas created from a font, but this complex logic is hidden from the user.

+@c Graphic3d_Aspects is a class defining **display properties** of a primitive array (@c Graphic3d_Group::SetGroupPrimitivesAspect()) -
+_**material**, **shading model**, **color**, **texture maps**, **blending mode**, **line width**_ and others.
+
+There are also subclasses @c Graphic3d_AspectFillArea3d (triangles), @c Graphic3d_AspectLine3d (lines), @c Graphic3d_AspectMarker3d (markers)
+and @c Graphic3d_AspectText3d (text labels) defined as specializations for a specific primitive array type.
+These subclasses exist for historical reasons and are treated by renderers in exactly the same way.
+
+It is technically possible to create transient aspects directly within @c @::Compute() method like this:
+
+~~~~{.cpp}
+void MyAisObject::Compute (const Handle(PrsMgr_PresentationManager)& thePrsMgr,
+                           const Handle(Prs3d_Presentation)& thePrs,
+                           const Standard_Integer theMode)
+{
+  Handle(Graphic3d_Aspects) anAspects = new Graphic3d_Aspects();
+  anAspects->SetShadingModel (Graphic3d_TypeOfShadingModel_Unlit);
+  anAspects->SetColor (Quantity_NOC_RED);
+  Handle(Graphic3d_Group) aGroup = thePrs->NewGroup();
+  aGroup->SetGroupPrimitivesAspect (anAspects);
+  ...
+}
+~~~~
+
+While this code would work as expected, but prevents further dynamic updates of presentation aspects without recomputing entire presentation.
+Instead, it is preferred taking attributes from @c PrsMgr_PresentableObject::myDrawer / @c @::Attributes() or storing custom attributes as class fields.
+@c Prs3d_Drawer defines a set of attributes used by @c AIS presentation builders, but the same parameters might be used by a custom builder as well.
+
+It is also preferred preallocating attributes in the class constructor.
+This would allow changing attributes without recomputing the entire presentation - just by calling @c PrsMgr_PresentableObject::SynchronizeAspects() after modifications.
+Our custom object uses @c myDrawer->ShadingAspect() and @c myDrawer->WireAspect() aspects, so let's initialize them explicitly - assign silver material for shading and green color to line segments:
+
+~~~~{.cpp}
+MyAisObject::MyAisObject()
+{
+  SetHilightMode (MyDispMode_Highlight);
+  myDrawer->SetupOwnShadingAspect();
+  myDrawer->ShadingAspect()->SetMaterial (Graphic3d_NameOfMaterial_Silver);
+  myDrawer->SetWireAspect (new Prs3d_LineAspect (Quantity_NOC_GREEN, Aspect_TOL_SOLID, 2.0));

+@section quadric_builders Quadric builders
+
+Previously, we've used @c StdPrs_ShadedShape for displaying cylinder geometry.
+The @c Prs3d package provides a simpler way for displaying geometry like cylinders, spheres and toruses - based on the @c Prs3d_ToolQuadric interface.
+This interface allows bypassing creation of a complex B-Rep (@c TopoDS_Shape) definition of a simple geometry, and to avoid using general-purpose tessellators like @c BRepMesh.
+
+> This difference could be negligible for a small number of such objects, but might become considerable for larger amounts.
+> The B-Rep definition of a valid cylinder includes 2 unique @c TopoDS_Vertex, 3 @c TopoDS_Edge, 3 @c TopoDS_Wire, 3 @c TopoDS_Face, 1 @c TopoDS_Shell and 1 @c TopoDS_Solid.
+> Internally each @c TopoDS_Edge also defines curves (@c Geom_Curve as well as 2D parametric @c Geom2d_Curve) and each @c TopoDS_Face defines analytical surface (@c Geom_Surface).
+> Meshing such geometry with the help of @c BRepMesh is much more complicated than one may think.
+> A plenty of data structures (memory!) and computations (time!) for displaying a geometry that could be triangulated by a simple for loop.
+
+@c Prs3d_ToolQuadric solves this problem by creating a triangulation for such kinds of shapes in a straight-forward way.
+Let's try using @c Prs3d_ToolCylinder in our sample:
+
+~~~~{.cpp}
+void MyAisObject::Compute (const Handle(PrsMgr_PresentationManager)& thePrsMgr,
+                           const Handle(Prs3d_Presentation)& thePrs,
+                           const Standard_Integer theMode)
+{
+  const double aRadius = 100.0, aHeight = 100.0;
+  TopoDS_Shape aShape = BRepPrimAPI_MakeCylinder (aRadius, aHeight);
+  if (theMode == MyDispMode_Main)
+  {
+	//StdPrs_ShadedShape::Add (thePrs, aShape, myDrawer); // add shading
+	//StdPrs_WFShape::Add (thePrs, aShape, myDrawer); // add wireframe
+	Handle(Graphic3d_ArrayOfTriangles) aTris =
+     Prs3d_ToolCylinder::Create (aRadius, aRadius, aHeight, 10, 10, gp_Trsf());
+	Handle(Graphic3d_Group) aGroupTris = thePrs->NewGroup();
+	aGroupTris->SetGroupPrimitivesAspect (myDrawer->ShadingAspect()->Aspect());
+	aGroupTris->AddPrimitiveArray (aTris);
+	...

+
+Well... that looks a little bit edgy.
+Quadric builder creates a triangulation taking the following parameters:
+- Geometry parameters.
+  (in case of a cylinder - base radius, top radius and height).
+- Number of subdivisions along U (slices) and V (stacks) parameters.
+  In some cases only one parametric scope matters.
+- Transformation @c gp_Trsf to apply
+  (original geometry is defined within some reference coordinate system).
+
+Let's increase number of subdivisions from _10_ to _25_:
+~~~~{.cpp}
+Handle(Graphic3d_ArrayOfTriangles) aTris =
+  Prs3d_ToolCylinder::Create (aRadius, aRadius, aHeight, 25, 25, gp_Trsf());
+~~~~
+
+@figure{ais_object_step3_quadrics_25.png,"@c Prs3d_ToolCylinder (25 slices).",409} height=409px
+
+It looks much better now! Note that @c Prs3d_ToolCylinder could be used for building both cones and cylinders depending on top/bottom radius definition.
+
+There is one issue though - our cylinder doesn't have top and bottom anymore!
+To fix this problem we will use one more quadric builder @c Prs3d_ToolDisk:
+
+~~~~{.cpp}
+void MyAisObject::Compute (const Handle(PrsMgr_PresentationManager)& thePrsMgr,
+                           const Handle(Prs3d_Presentation)& thePrs,
+                           const Standard_Integer theMode)
+{
+  const double aRadius = 100.0, aHeight = 100.0;
+  if (theMode == MyDispMode_Main)
+  {
+    Prs3d_ToolCylinder aCyl (aRadius, aRadius, aHeight, 25, 25);
+    Prs3d_ToolDisk aDisk (0.0, aRadius, 25, 1);
+
+    Handle(Graphic3d_ArrayOfTriangles) aTris =
+      new Graphic3d_ArrayOfTriangles (aCyl.VerticesNb() + 2 * aDisk.VerticesNb(),
+                                      3 * (aCyl.TrianglesNb() + 2 * aDisk.TrianglesNb()),
+                                      Graphic3d_ArrayFlags_VertexNormal);
+    aCyl .FillArray (aTris, gp_Trsf());
+    aDisk.FillArray (aTris, gp_Trsf());
+
+    gp_Trsf aDisk2Trsf;
+    aDisk2Trsf.SetTransformation (gp_Ax3 (gp_Pnt (0.0, 0.0, aHeight), -gp::DZ(), gp::DX()), gp::XOY());
+    aDisk.FillArray (aTris, aDisk2Trsf);
+
+    Handle(Graphic3d_Group) aGroupTris = thePrs->NewGroup();
+    aGroupTris->SetGroupPrimitivesAspect (myDrawer->ShadingAspect()->Aspect());
+    aGroupTris->AddPrimitiveArray (aTris);
+    aGroupTris->SetClosed (true);
+    ...
+  }
+}
+~~~~
+
+Now our cylinder looks solid! The sample above merges two triangulations into a single one instead of appending each primitive array individually.
+
+This looks like a minor difference, but it might have a _dramatic impact on performance_ in case of a large scene,
+as each `Graphic3d_ArrayOfPrimitives` is mapped into a dedicated draw call at graphic driver (OpenGL) level.
+
+@figure{ais_object_step3_quadrics_fin.png,"@c Prs3d_ToolCylinder + @c Prs3d_ToolDisk.",409} height=409px
+
+As an exercise, let's try computing a triangulation for cylinder disk without help of @c Prs3d_ToolDisk builder:
+
+~~~~{.cpp}

+                           const Handle(Prs3d_Presentation)& thePrs,

+
+@figure{ais_object_step3_quadrics_disk.png,"Manually triangulated disk.",409} height=409px
+
+The disk is here, but it has a strange color - like it is not affected by lighting.
+This happens when vertex normals are defined incorrectly.
+In our case we defined disk normal as @c -DZ (see the second argument of @c Graphic3d_ArrayOfTriangles::AddVertex()),
+but normal direction should be also aligned to triangulation winding rule.
+Graphic driver defines the front side of triangle using clockwise order of triangle nodes, and normal should be defined for a front side of triangle - e.g. it should be @c gp::DZ() in our case.
+After reversing vertex normal direction, cylinder looks exactly like when @c Prs3d_ToolDisk was used.
+
+Front / back face orientation might be displayed using different material based on @c Graphic3d_Aspects::SetDistinguish() flag and @c @::FrontMaterial() / @c @::BackMaterial() setup.
+
+@section ais_selection Computing selection
+In the first part of the tutorial we have created a custom @c AIS object @c MyAisObject computing presentation by implementing the @c PrsMgr_PresentableObject::Compute() interface.
+In this part we will extend our object with interactive capabilities and make it selectable through implementing @c SelectMgr_SelectableObject interface.
+
+Let's do the first step and put into @c @::ComputeSelection() method some logic.
+This method should fill in the @c SelectMgr_Selection argument with @c SelectMgr_SensitiveEntity entities defining selectable elements - triangulations, polylines, points and their composition.
+@c Select3D_SensitiveBox is probably the simplest way to define selectable volume - by it's bounding box:
+
+~~~~{.cpp}
+void MyAisObject::ComputeSelection (const Handle(SelectMgr_Selection)& theSel,
+                                    const Standard_Integer theMode)
+{
+  const double aRadius = 100.0, aHeight = 100.0;
+  TopoDS_Shape aShape = BRepPrimAPI_MakeCylinder (aRadius, aHeight);
+  Bnd_Box aBox;
+  BRepBndLib::Add (aShape, aBox);
+  Handle(SelectMgr_EntityOwner) anOwner = new SelectMgr_EntityOwner (this);
+  Handle(Select3D_SensitiveBox) aSensBox = new Select3D_SensitiveBox (anOwner, aBox);
+  theSel->Add (aSensBox);
+}
+~~~~
+
+@c SelectMgr_EntityOwner is a key object in selection logic - it serves as an identifier of a pickable object or it's part.
+You may see this object in methods like @c AIS_InteractiveContext::DetectedOwner(), **Owners** are stored within the list of selection objects @c AIS_Selection
+and it received by methods like @c AIS_InteractiveContext::SetSelected() and @c AIS_InteractiveContext::AddOrRemoveSelected().
+From the Selector's point of view, @c AIS_InteractiveObject is just a drawer for @c SelectMgr_EntityOwner.
+
+The _**0th selection mode**_ normally defines a single Owner of the entire object.
+To make a composite object selectable as whole, we add to Selection as many SensitiveEntity as necessary referring to the same Owner.
+It might look confusing from first glance, that @c SelectMgr_SensitiveEntity stores @c SelectMgr_EntityOwner as a class field, and not in the opposite way
+(@c SelectMgr_EntityOwner doesn't store the list of @c SelectMgr_SensitiveEntity defining it's picking volume).
+
+For local selection (selection of object parts) we create individual Owners for each part and add SensitiveEntity to Selection in the same way.
+Owner may store an additional identifier as a class field, like @c StdSelect_BRepOwner stores @c TopoDS_Shape as an identifier of picked sub-shape with @c AIS_Shape object.
+
+In a similar way as @c StdPrs_ShadedShape is a **presentation builder** for @c TopoDS_Shape, the @c StdSelect_BRepSelectionTool can be seen as a standard **selection builder** for shapes:
+
+~~~~{.cpp}
+void MyAisObject::ComputeSelection (const Handle(SelectMgr_Selection)& theSel,
+                                    const Standard_Integer theMode)
+{
+  const double aRadius = 100.0, aHeight = 100.0;
+  TopoDS_Shape aShape = BRepPrimAPI_MakeCylinder (aRadius, aHeight);
+  Standard_Real aDefl = StdPrs_ToolTriangulatedShape::GetDeflection (aShape, myDrawer);
+  StdSelect_BRepSelectionTool::Load (theSel, this, aShape, TopAbs_SHAPE, aDefl,
+                                     myDrawer->DeviationAngle(),
+                                     myDrawer->IsAutoTriangulation());
+}
+~~~~
+
+Internally, @c StdSelect_BRepSelectionTool iterates over sub-shapes and appends to the Selection (@c theSel) entities like @c Select3D_SensitiveTriangulation (for faces) and @c Select3D_SensitiveCurve (for edges).
+
+Previously, we have used @c Prs3d_ToolCylinder to triangulate a cylinder, so let's try to construct @c Select3D_SensitivePrimitiveArray from the same triangulation:
+
+~~~~{.cpp}
+void MyAisObject::ComputeSelection (const Handle(SelectMgr_Selection)& theSel,
+                                    const Standard_Integer theMode)
+{
+  const double aRadius = 100.0, aHeight = 100.0;
+  Handle(SelectMgr_EntityOwner) anOwner = new SelectMgr_EntityOwner (this);
+  Handle(Graphic3d_ArrayOfTriangles) aTris =
+    Prs3d_ToolCylinder::Create (aRadius, aRadius, aHeight, 25, 25, gp_Trsf());
+  Handle(Select3D_SensitivePrimitiveArray) aSensTri =
+    new Select3D_SensitivePrimitiveArray (anOwner);
+  aSensTri->InitTriangulation (aTris->Attributes(), aTris->Indices(),
+                               TopLoc_Location());
+  theSel->Add (aSensTri);
+}
+~~~~
+
+Selection is computed independently from presentation, so that they don't have to match each other.
+But inconsistency between presentation and selection might confuse a user, when he will not be able to pick an object clearly displayed under the mouse cursor.
+These issues might happen, for example, when selection uses tessellated representation of the same geometry computed with different parameters (different number of subdivisions, or different deflection parameters).
+
+As in case of @c @::Compute(), it makes sense defining some enumeration of **selection modes** supported by specific object and reject unsupported ones to avoid unexpected behavior:
+
+~~~~{.cpp}
+void MyAisObject::ComputeSelection (const Handle(SelectMgr_Selection)& theSel,
+                                    const Standard_Integer theMode)
+{
+  if (theMode != 0) { return; }
+  ...
+}
+~~~~
+
+Unlike display modes, @c AIS_InteractiveContext allows activating an arbitrary combination of selection modes.
+A user should be careful to activate only the modes that actually make sense and may work together.
+
+Selection mode to activate could be specified while displaying the object (passing _**-1**_ instead of _**0**_ would display an object with deactivated selection):
+
+~~~~{.cpp}
+Handle(AIS_InteractiveContext) theCtx;
+Handle(MyAisObject) aPrs = new MyAisObject();
+theCtx->Display (aPrs, MyAisObject::MyDispMode_Main, 0, false);
+~~~~
+
+Later on @c AIS_InteractiveContext::SetSelectionModeActive(), or it's wrappers @c AIS_InteractiveContext::Activate() and @c AIS_InteractiveContext::Deactivate(),
+could be used to enable or disable desired selection modes one by one.
+
+@section sel_owner_highlight Highlighting selection owner
+
+As has been mentioned in the previous section, @c SelectMgr_EntityOwner is a key object which can be used as an identifier of selectable part(s).
+Naturally, you might want to subclass it to put some application-specific ids for identification of selected parts.
+But there are more things you may do with the Owner class like customized highlighting.
+
+Let's start from the beginning and define a custom Owner class:
+
+~~~~{.cpp}
+class MyAisOwner : public SelectMgr_EntityOwner
+{
+  DEFINE_STANDARD_RTTI_INLINE(MyAisOwner, SelectMgr_EntityOwner)
+public:
+  MyAisOwner (const Handle(MyAisObject)& theObj, int thePriority = 0)
+  : SelectMgr_EntityOwner (theObj, thePriority) {}
+
+  virtual void HilightWithColor (const Handle(PrsMgr_PresentationManager)& thePrsMgr,
+                                 const Handle(Prs3d_Drawer)& theStyle,
+                                 const Standard_Integer theMode) override
+  { base_type::HilightWithColor (thePrsMgr, theStyle, theMode); }
+
+  virtual void Unhilight (const Handle(PrsMgr_PresentationManager)& thePrsMgr,
+                          const Standard_Integer theMode) override
+  { base_type::Unhilight  (thePrsMgr, theMode); }
+protected:
+  Handle(Prs3d_Presentation) myPrs;
+};
+~~~~
+
+@c SelectMgr_EntityOwner doesn't define any pure virtual methods, and can be instanced straight ahead, like it was done within @c MyAisObject::ComputeSelection() implementation above.
+Let's revert usage of a dedicated display mode for highlighting (remove @c SetHilightMode() in @c MyAisObject constructor) and use our new class @c MyAisOwner within @c @::ComputeSelection():
+
+~~~~{.cpp}
+MyAisObject::MyAisObject()
+{
+  //SetHilightMode (MyDispMode_Highlight);
+  myDrawer->SetupOwnShadingAspect();
+  ...
+}
+
+void MyAisObject::ComputeSelection (const Handle(SelectMgr_Selection)& theSel,
+                                    const Standard_Integer theMode)
+{
+  const double aRadius = 100.0, aHeight = 100.0;
+  Handle(MyAisOwner) anOwner = new MyAisOwner (this);
+  ...
+}
+~~~~
+
+The further logic creating sensitive entities and filling in Selection could be left as is.
+Substitution of @c SelectMgr_EntityOwner with @c MyAisOwner currently doesn't change behavior and we see highlighting of the entire object through color modulation.
+This is because default implementation of @c SelectMgr_EntityOwner for highlighting logic looks like this (simplified):
+
+~~~~{.cpp}
+void SelectMgr_EntityOwner::HilightWithColor (
+  const Handle(PrsMgr_PresentationManager)& thePrsMgr,
+  const Handle(Prs3d_Drawer)& theStyle,
+  const Standard_Integer theMode)
+{
+  const Graphic3d_ZLayerId aHiLayer =
+      theStyle->ZLayer() != Graphic3d_ZLayerId_UNKNOWN
+    ? theStyle->ZLayer()
+    : mySelectable->ZLayer();
+  thePrsMgr->Color (mySelectable, theStyle, theMode, NULL, aHiLayer);
+}
+~~~~
+
+@figure{ais_object_step4_highlight1.png,"Default behavior of @c SelectMgr_EntityOwner::HilightWithColor().",409} height=409px
+
+Now, let's override the @c SelectMgr_EntityOwner::HilightWithColor() method and display a bounding box presentation:
+
+~~~~{.cpp}
+void MyAisOwner::HilightWithColor (const Handle(PrsMgr_PresentationManager)& thePrsMgr,
+                                   const Handle(Prs3d_Drawer)& theStyle,
+                                   const Standard_Integer theMode)
+{
+  if (myPrs.IsNull())
+  {
+    myPrs = new Prs3d_Presentation (thePrsMgr->StructureManager());
+    MyAisObject* anObj = dynamic_cast<MyAisObject*> (mySelectable);
+    anObj->Compute (thePrsMgr, myPrs, MyAisObject::MyDispMode_Highlight);
+  }
+  if (!thePrsMgr->IsImmediateModeOn())
+  {
+    myPrs->Display();
+  }
+}
+~~~~
+
+@c SelectMgr_EntityOwner::HilightWithColor() doesn't receive a presentation to fill in as an argument; highlight presentation should be manually created and even explicitly displayed on the screen.
+To avoid code duplication, the code above reuses @c MyAisObject::Compute() already implementing computation of highlight presentation.
+
+@figure{ais_object_step4_highlight2.png,"Result of custom implementation @c MyAisOwner::HilightWithColor().",409} height=409px
+
+The visual result of the selected object looks exactly the same as when we've used a dedicated highlight mode.
+One thing became broken, though - highlighting remains displayed even after clearing selection.
+To fix this issue, we need implementing @c SelectMgr_EntityOwner::Unhilight() and hide our custom presentation explicitly:
+
+~~~~{.cpp}
+void MyAisOwner::Unhilight (const Handle(PrsMgr_PresentationManager)& thePrsMgr,
+                            const Standard_Integer theMode)
+{
+  if (!myPrs.IsNull()) { myPrs->Erase(); }
+}
+~~~~
+
+Another problem is that the object is no longer dynamically highlighted.
+To fix that we need to handle @c PrsMgr_PresentationManager::IsImmediateModeOn() specifically.
+Within this mode turned ON, presentation should be displayed on the screen with help of @c PrsMgr_PresentationManager::AddToImmediateList() method
+(it will be cleared from the screen automatically on the next mouse movement):
+
+~~~~{.cpp}
+void MyAisOwner::HilightWithColor (const Handle(PrsMgr_PresentationManager)& thePrsMgr,
+                                   const Handle(Prs3d_Drawer)& theStyle,
+                                   const Standard_Integer theMode)
+{
+  if (myPrs.IsNull())
+  {
+    myPrs = new Prs3d_Presentation (thePrsMgr->StructureManager());
+    MyAisObject* anObj = dynamic_cast<MyAisObject*> (mySelectable);
+    anObj->Compute (thePrsMgr, myPrs, MyAisObject::MyDispMode_Highlight);
+  }
+  if (thePrsMgr->IsImmediateModeOn())
+  {
+    Handle(Prs3d_PresentationShadow) aShadow =
+      new Prs3d_PresentationShadow (thePrsMgr->StructureManager(), myPrs);
+    aShadow->SetZLayer (Graphic3d_ZLayerId_Top);
+    aShadow->Highlight (theStyle);
+    thePrsMgr->AddToImmediateList (aShadow);
+  }
+  else
+  {
+    myPrs->Display();
+  }
+}
+~~~~
+
+We may create two dedicated presentations for dynamic highlighting or reuse existing one for both cases with help of a transient object @c Prs3d_PresentationShadow.
+
+Let's go further and make dynamic highlighting a little bit more interesting - by drawing a surface normal at the point where mouse picked the object:
+
+~~~~{.cpp}
+void MyAisOwner::HilightWithColor (const Handle(PrsMgr_PresentationManager)& thePrsMgr,
+                                   const Handle(Prs3d_Drawer)& theStyle,

+
+Code above does not store our new highlight presentation as a property of @c MyAisOwner, and instead uses @c SelectMgr_SelectableObject::GetHilightPresentation() method
+to create a presentation stored directly inside of our interactive object.
+
+Next trick is passing through the last picking results in @c StdSelect_ViewerSelector.
+Dynamic highlighting is expected to be called right after picking, so that highlighted Owner should be always found in picking results.
+@c StdSelect_ViewerSelector::Picked() returns entities in the descending order of their distance from picking ray origin (mouse cursor);
+normally our Owner should be the very first one in this list when no selection filters are assigned to @c AIS_InteractiveContext.
+
+@c SelectMgr_SortCriterion provides us useful information like 3D point on detected object lying on the picking ray, and surface normal direction at this point (actually, it would be a normal to a picked triangle),
+which we display as an arrow with help of @c Prs3d_Arrow presentation builder.
+
+@figure{ais_object_step4_highlight3.png,"Surface normal on mouse over.",409} height=409px
+
+Result looks pretty nice on the screenshot, but has interaction problems - once displayed, an arrow is no longer updated with further mouse movements.
+But this behavior is not a bug - @c AIS calls @c MyAisOwner::HilightWithColor() only when picking Owner changes to avoid unnecessary Viewer updates.
+To override this behavior, we may override @c SelectMgr_EntityOwner::IsForcedHilight() option:
+
+~~~~{.cpp}
+class MyAisOwner : public SelectMgr_EntityOwner
+{
+...
+  virtual bool IsForcedHilight() const override { return true; }
+};
+~~~~
+
+This solves the problem within our specific use case.
+Keep in mind that most objects don't need updating highlight presentation on every mouse move;
+overriding this flag everywhere would be a waste of resources and may cause performance issues - use it sparingly.
+
+@section highlight_apporaches Highlighting approaches
+
+@c AIS provides one more alternative to handle presentation highlighting, which is managed by option @c SelectMgr_SelectableObject::IsAutoHilight().
+By default, this option is turned ON and redirects highlighting logic to @c SelectMgr_EntityOwner::HilightWithColor() demonstrated in the previous section.
+Turning this option OFF redirects highlighting logic to the interactive object itself @c SelectMgr_SelectableObject::HilightSelected().
+
+Apart from moving the logic from Owner to Interactive Object, this approach allows handling highlighting of all selected Owners within the same Object at once and sharing a common presentation
+instead of per-Owner presentation - improving performance and reducing memory utilization in case of a large number of small selectable elements, like mesh nodes in @c MeshVS_Mesh object.
+
+The further optimization of such a scenario would be using a single Owner for the entire Object
+storing the list of selected elements within the Owner itself - as utilized by @c AIS_PointCloud object for highlighting individual points.
+
+We wouldn't describe these advanced techniques here in detail - let's just summarize main highlighting approaches available in @c AIS:
+- Highlighting of a main presentation of Interactive Object (active display mode)
+  filled in by @c PrsMgr_PresentableObject::Compute()
+  and displayed with color modulation by @c AIS logic.
+  - Example: @c AIS_TextLabel.
+- Highlighting of a secondary presentation of Interactive Object
+  filled in by @c PrsMgr_PresentableObject::Compute()
+  and displayed with color modulation by @c AIS logic.
+  - Example: @c AIS_Shape, displayed in @c AIS_Shaded display mode and highlighted using @c AIS_Wireframe display mode (default behavior).
+    See also @c PrsMgr_PresentableObject::SetHilightMode().
+- Highlight presentation stored within a custom @c SelectMgr_EntityOwner
+  and managed by @c SelectMgr_EntityOwner::HilightWithColor().
+  - Example: @c StdSelect_BRepOwner for selection of sub-shapes.
+- Custom highlight presentation stored within Interactive Object itself
+  (see @c SelectMgr_SelectableObject::GetHilightPresentation() / @c @::GetSelectPresentation() methods).
+  - Filled in by @c SelectMgr_EntityOwner::HilightWithColor()
+    with @c SelectMgr_SelectableObject::IsAutoHilight() turned ON.<br>
+    Example: @c AIS_PointCloud.
+  - Filled in by @c SelectMgr_SelectableObject::HilightSelected()
+    with @c SelectMgr_SelectableObject::IsAutoHilight() turned OFF.<br>
+    Example: @c MeshVS_Mesh.
+- Main presentation of Interactive Object (active display mode)
+  filled in by @c PrsMgr_PresentableObject::Compute()
+  and manually updated (recomputed or modified aspects) on highlight events.
+  - Example: @c AIS_Manipulator.
+
+The number of options looks overwhelming but in general, it is better to stick to the simplest approach working for you and consider alternatives only when you have to.
+
+@section mouse_click Mouse click
+
+Dynamic highlighting is only one of scenarios where @c SelectMgr_EntityOwner could be useful.
+Another feature is an interface for handling a mouse click @c SelectMgr_EntityOwner @c @::HandleMouseClick().
+
+This interface is useful for defining some user interface elements like buttons, and most likely your application will use a more comprehensive GUI framework for this purpose instead of @c AIS.
+But let's have some fun and make our object to change a color on each mouse click:
+
+~~~~{.cpp}
+class MyAisOwner : public SelectMgr_EntityOwner
+{
+...
+  virtual bool HandleMouseClick (const Graphic3d_Vec2i& thePoint,
+                                 Aspect_VKeyMouse theButton,
+                                 Aspect_VKeyFlags theModifiers,
+                                 bool theIsDoubleClick) override;
+};
+
+bool MyAisOwner::HandleMouseClick (const Graphic3d_Vec2i& thePoint,
+                                   Aspect_VKeyMouse theButton,
+                                   Aspect_VKeyFlags theModifiers,
+                                   bool theIsDoubleClick)
+{
+  static math_BullardGenerator aRandGen;
+  Quantity_Color aRandColor (float(aRandGen.NextInt() % 256) / 255.0f,
+                             float(aRandGen.NextInt() % 256) / 255.0f,
+                             float(aRandGen.NextInt() % 256) / 255.0f,
+                             Quantity_TOC_sRGB);
+  mySelectable->Attributes()->ShadingAspect()->SetColor(aRandColor);
+  mySelectable->SynchronizeAspects();
+  return true;
+}
+~~~~
+
+Looks pretty simple. Now let's make things more interesting and launch some simple object animation on each click.
+We use a couple of global (@c static) variables in our sample for simplicity - don't do that in a real production code.
+
+~~~~{.cpp}
+class MyAisOwner : public SelectMgr_EntityOwner
+{
+...
+  void SetAnimation (const Handle(AIS_Animation)& theAnim)
+  { myAnim = theAnim; }

+};

+                                   Aspect_VKeyMouse theButton,
+                                   Aspect_VKeyFlags theModifiers,
+                                   bool theIsDoubleClick)
+{
+  static bool isFirst = true;
+  isFirst = !isFirst;
+  MyAisObject* anObj = dynamic_cast<MyAisObject*> (mySelectable);
+  gp_Trsf aTrsfTo;
+  aTrsfTo.SetRotation (gp_Ax1 (gp::Origin(), gp::DX()),
+                       isFirst ? M_PI * 0.5 : -M_PI * 0.5);
+  gp_Trsf aTrsfFrom = anObj->LocalTransformation();
+  Handle(AIS_AnimationObject) anAnim =
+    new AIS_AnimationObject ("MyAnim", anObj->InteractiveContext(),
+                             anObj, aTrsfFrom, aTrsfTo);
+  anAnim->SetOwnDuration (2.0);
+
+  myAnim->Clear();
+  myAnim->Add (anAnim);
+  myAnim->StartTimer (0.0, 1.0, true);
+  return true;
+}
+~~~~
+
+Animation is a complex topic that is worth a dedicated article - let's not go too deep in detail here.
+To perform animation in a non-interrupted way, it should be handled by some class like @c AIS_ViewController, which is responsible for managing user input events and for 3D viewer updates.
+To utilize it, you need adding a custom object animation to @c AIS_ViewController::ObjectsAnimation() or adding custom view animation to @c AIS_ViewController::ViewAnimation().
+Somewhere in application this might look like this:
+
+~~~~{.cpp}
+Handle(AIS_InteractiveContext) theCtx;
+Handle(AIS_ViewController) theViewCtrl;
+Handle(MyAisObject) aPrs = new MyAisObject();
+aPrs->SetAnimation (theViewCtrl->ObjectsAnimation());
+theCtx->Display (aPrs, MyAisObject::MyDispMode_Main, 0, false);

+@section diffs Modeling with OCCT: Key differences
+
+Open CASCADE Technology (OCCT) is an object-oriented C++ framework designed for rapid production of sophisticated CAD/CAM/CAE applications.
+In other words, it provides endless possibilities for raw 2D and 3D modeling in C++ environment.
+Unlike end-user software, it is used by the application developers and therefore strongly differs from the most popular CAD/CAM/CAE software packages.
+OCCT provides building blocks enough for modeling, editing, visualization, and data interoperability of 2D and 3D objects.
+
+By using OCCT, users can create the objects of their desire (or edit already existing ones) using raw code commands.
+It is a more complicated process than using GUI-based software, but it provides much more flexibility than even script-based manipulations that are available within existing CAD/CAM/CAE applications.
+However, to fully grasp the possibilities of OCCT it is best for the user to have previous experience in C++ at least at a basic level.
+
+@section basics Understanding the principles
+
+If you don't have any programming skills, grasping the full magnitude of OCCT workflow is still an option.
+The documentation for OCCT contains several entry points for new users.
+It will not explain all OCCT classes but will help to comprehend the workflow and help start thinking in terms of Open CASCADE Technology.
+
+The most basic workflow is described in the @ref occt__tutorial "OCCT Tutorial" - this is an excellent starting point for new users.
+In this tutorial you will create a solid model step-by-step using different classes and methods.
+Each step of the tutorial contains code snippets and images.
+
+The basics involved in the modeling process are explained.
+When the basics of OCCT are clear, the next logical step is to check out @ref samples "sample applications" and examine those that suit your needs.
+For these, the best starting point is **OCCTOverview** located in /samples/qt subfolder of OCCT installation.
+
+This sample provides code examples for several actions as well as visualization of these code snippets output.
+The Overview interface is dynamically changing based on selected **Category** at the menu.
+Additional menu buttons will appear, providing users with subcategories and relevant commands to select one of the actions.
+The result will appear in the viewer window, the code will appear at the top right, and in several cases the output will be produced at the bottom right window.
+
+@figure{sample_overview_qt_viewers.png,"Comparison of 3D and 2D viewer windows",240} height=420px
+
+The 3D viewer window has a row of preset interface buttons to customize the visual output.
+
+Those buttons can be grouped into three types, left to right:
+
+- View controls: **Fit all** and **Isometric**, will center the view and reset the camera angles respectively;
+- Display mode customization: **HLR,** e.g. "Hidden line removal" (works only when shading is disabled) can be turned on and off;
+solid models may be displayed either in **Shading** or **Wireframe** modes. **Transparency** level may be set for models in shading mode;
+- The last four buttons in a row are beautifiers enabling Ray-tracing engine and configuring it's parameters.
+
+At the bottom left of the screen the orientation cube (trihedron) is located.
+The trihedron interactively shows the position of the camera in relation to the XYZ axis of the displayed data.
+The sides of the trihedron are labeled to help with orientation.
+Click on a side of the box to orient the camera view along the preferred axis.
+
+The 2D viewer window lacks most of these elements and only have **Fit all** button.
+
+The **Geometry** category of the Overview focuses on primitive objects like dots, lines (including vectors) or planes.
+These objects will appear in the viewer after the subcategory is selected.
+This section will demonstrate these entities both in 2D and 3D view mode and provide basic examples of parametric creation and data analysis.
+
+@figure{sample_overview_qt_geometry.png,"",240} height=440px
+
+The usage of the functions shown in the Overview is described more thoroughly at the @ref occt_user_guides__modeling_data "Modeling data" section of the documentation.
+Additionally, @ref occt_user_guides__modeling_algos "Modeling Algorithms" are used in more complex cases.
+
+The **Topology** section of the Overview demonstrates the functions used in 3D operations.
+Multiple use cases are provided, including different object intersections, modifying and calculations.
+Some of these use cases are described in the documentation, such as @ref occt_user_guides__inspector "Inspector" usage.
+
+@figure{sample_overview_qt_topology.png,"",240} height=440px
+
+The subsections are grouped as shown on the screenshot before.
+Most shapes and primitive objects are introduced and then followed by a set of operations and interactions.
+
+The **Triangulation** segment allows computing the number of triangles on a shape.
+
+This may be inspected via [Poly_Triangulation Class Reference](https://dev.opencascade.org/doc/refman/html/class_poly___triangulation.html) -
+a part of the [Reference manual](https://dev.opencascade.org/doc/refman/html/index.html),
+an overall Open CASCADE code guide that may be used to inspect the key points in classes and their connections.
+
+@figure{sample_overview_qt_triangulation.png,"",240} height=440px
+
+The triangulation uses some of Mesh-related classes - see full description at @ref occt_user_guides__mesh "Mesh" documentation section.
+
+The **Data exchange** section provides examples of how to export and import files of several different formats.
+
+@figure{sample_overview_qt_xde.png,"",240} height=440px
+
+The **OCAF** section gives an introduction for the @ref intro_overview_ocaf "Open CASCADE Application Framework" functionality.
+To test these functions, create an object first (box or cylinder).
+After that, the object may be modified and saved. Actions are recorded and may be undone or redone.
+
+@figure{sample_overview_qt_ocaf.png,"",240} height=440px
+
+**Viewers** section demonstrates examples of the 2D and 3D visualization outputs.
+Check @ref occt_user_guides__visualization "Visualization" section of the documentation for a detailed description.
+In addition to these two samples, there are much more that might be of use to a new user based on their particular use case.
+
+Check Readme files in the sample directories to learn more about samples compilation.
+
+**Note:** source code for OCCTOverview is stored at 'samples/qt/OCCTOverview/src' folder in your OCCT root,
+and the source code files for examples presented in subsections are stored at 'samples/OCCTOverview/code folder'.
+Several utility classes that are not presented in the example window may be found in example source code files.
+
+The overall classes introduction may be found in the @ref occt_user_guides__foundation_classes "Foundation Classes" section of the documentation.
+The "Introduction" section contains short descriptions of the most massive entries in the documentation.
+
+@section helps Additional assistance
+
+There are several places that may be of use for new users.
+The first one is [Training & E-learning](https://dev.opencascade.org/resources/trainings) page that lists available trainings and describes their specifics.
+
+The second one is the Overview documentation (this document is a part of it) - here you can find information that suits most of the use cases.
+This may seem overwhelming at first, but if you have the clear understanding of what do you seek, you will most likely find the required information.
+
+Aside from the Overview documentation itself, the [Reference manual](https://dev.opencascade.org/doc/refman/html/index.html) is present.
+Use it to check classes descriptions, dependencies and examples.
+Additionally, there is a [Forum](https://dev.opencascade.org/forums) where you can contact the OCCT community and developers.

+OCAF: Usage Tutorial {#samples__ocaf}
 ========
 
-## Getting  Started
+## Getting Started
+
+At the beginning of your development, you first define an application class by inheriting from the Application abstract class.
+You only have to create and determine the resources of the application for specifying the format of your documents (you generally use the standard one) and their file extension.
+
+Then, you design the application data model by organizing attributes you choose among those provided with OCAF.
+You can specialize these attributes using the User attribute. For example, if you need a reflection coefficient,
+you aggregate a User attribute identified as a reflection coefficient
+with a Real attribute containing the value of the coefficient (as such, you don't define a new class).
+
+If you need application specific data not provided with OCAF, for example, to incorporate a finite element model in the data structure,
+you define a new attribute class containing the mesh, and you include its persistent homologue in a new file format.
+
+Once you have implemented the commands which create and modify the data structure according to your specification, OCAF provides you, without any additional programming:
+
+* Persistent reference to any data, including geometric elements - several documents can be linked with such reference;
+* Document-View association;
+* Ready-to-use functions such as:
+  * Undo-redo;
+  * Save and open application data.
+
+Finally, you develop the application's graphical user interface using the toolkit of your choice, for example:
+* KDE Qt or GNOME GTK+ on Linux;
+* Microsoft Foundation Classes (MFC) on Windows Motif on Sun;
+* Other commercial products such as Ilog Views.
+
+You can also implement the user interface in the Java language using the Swing-based Java Application Desktop component (JAD) provided with OCAF.

+@section upgrade_occt770 Upgrade to OCCT 7.7.0
+
+Building OCCT now requires C++11-compliant compiler, so that some legacy compilers (Visual Studio 2010 and 2012) are no more supported.
+It is recommended using Visual Studio 2015 or newer for building OCCT on Windows platform.

+@subsection upgrade_770_removed_features Removed features
+
+* One of the constructors of the BRepExtrema_DistanceSS class (the one without deflection parameter) has been removed as excessive. The remaining constructor has to be used instead.

+ - BRepCheck_Edge
+ - BRepLib_ValidateEdge
+ - GeomLib_CheckCurveOnSurface
+ - BRepLib_CheckCurveOnSurface
+

+This header, as well as `OpenGl_GlCore20.hxx` and similar, no more include system OpenGL / OpenGL ES headers to define function table.
+Application code calling OpenGL functions directly should be changed to either use `OpenGl_Context::core11fwd` (as designed)
