A new flag Prs3d_Drawer::FaceBoundaryUpperContinuity() has been introduced
handled by StdPrs_ShadedShape::FillFaceBoundaries() method to exclude edges
of higher continuity class (e.g. to skip seam edges).
Draw Harness command vshowfaceboundary has been replaced by vaspects:
> vaspects -setFaceBoundaryDraw 1 -setFaceBoundaryColor RED -setFaceBoundaryType DASH.
Aspect_IS_HOLLOW now an alias to Aspect_IS_EMPTY and Aspect_IS_HIDDENLINE does not implicitly enables mesh edges,
so that Graphic3d_AspectFillArea3d::SetDrawEdges() should be set independently.
OpenGl_ShaderManager now provides built-in GLSL programs for drawing mesh edges
in single pass (and on OpenGL ES which does not provide glPolygonMode()).
Graphic3d_RenderingParams::ToEnableAlphaToCoverage is now enabled by default
and properly handled at TKOpenGl level - enables coverage for Graphic3d_AlphaMode_Mask primitives.
OpenGl_PrimitiveArray now uses GLSL programs instead of glPolygonMode() by default,
which can be managed by OpenGl_Caps::usePolygonMode flag (desktop OpenGL only).
glPolygonMode() is also used as fallback regardless OpenGl_Caps::usePolygonMode flag
when GLSL programs are not supported (Geometry Shaders are required)
or stipple line style is required (not implemented within Face GLSL).
vaspects command has been extended by -setInterior -setDrawEdges -setEdgeColor -setEdgeType -setEdgeWidth
arguments replacing vsetinteriorstyle/vsetedgetype/vunsetedgetype commands.
vaspects now accepts arguments without "set" prefix.
ViewerTest::ParseColor() now parses RGBA color.
Redundant command BUC60738 has been removed.
AIS_ColorScale - fixed usage of uninitialized FillArea aspects.
Font_FontMgr has been redesigned to:
- Store fonts in a map instead a list.
- Allow mapping multiple fonts to a single alias.
- Log informative message about usage of non-requested font (fallback).
- Register all font files within standard folders on Linux when "fonts.dir" is not found.
- Prefer specific alias ("serif") as default fallback font instead of arbitrary one in a system.
A couple of obsolete and broken font aliases have been removed;
instead, new aliases of fonts popular on Linux platform have been added.
Font_NameOfFont.hxx has been extended with more neutral aliases
"monospace", "serif", "sans-serif", "cjk" and "korean".
Font_FontAspect enumeration values have been renamed Font_FA_ -> Font_FontAspect_
with old values preserved as alias.
Font_SystemFont has been extended with a list of paths to Font_FontAspect styles,
so that entire Font Family is now defined within a single Font_SystemFont instance.
Non-resizable fonts are now ignored by Font Manager.
Add new command "vstatprofiler" to manage rendering parameters and print them.
If there are some input parameters - print corresponding statistic counters values,
else - print all performance counters set previously.
Frustum culling is now managed by Graphic3d_RenderingParams::FrustumCullingState flag
and can be switched into Graphic3d_RenderingParams::FrustumCulling_NoUpdate state
useful for debugging the algorithm.
Draw Harness command vrustumculling has been replaced by vrenderparams -frustumCulling.
1) Added method Graphic3d_Camera::FrustumPoints() returning corner points of camera frustum.
2) Refactored methods OpenGl_BVHTreeSelector::isFullOut(...) and OpenGl_BVHTreeSelector::CacheClipPtsProjections()
3) Changed computation algorithm of frustum planes (build them by corner points)
4) Added interactive object AIS_CameraFrustum to draw camera frustum.
5) Extended Draw command "vcamera" with option displaying camera frustum.
Removed tight connections between data structures, auxiliary tools and algorithms in order to create extensible solution, easy for maintenance and improvements;
Code is separated on several functional units responsible for specific operation for the sake of simplification of debugging and readability;
Introduced new data structures enabling possibility to manipulate discrete model of particular entity (edge, wire, face) in order to perform computations locally instead of processing an entire model.
The workflow of updated component can be divided on six parts:
* Creation of model data structure: source TopoDS_Shape passed to algorithm is analyzed and exploded on faces and edges. For each topological entity corresponding reflection is created in data model. Note that underlying algorithms use data model as input and access it via common interface which allows user to create custom data model with necessary dependencies between particular entities;
* Discretize edges 3D & 2D curves: 3D curve as well as associated set of 2D curves of each model edge is discretized in order to create coherent skeleton used as a base in faces meshing process. In case if some edge of source shape already contains polygonal data which suites specified parameters, it is extracted from shape and stored to the model as is. Each edge is processed separately, adjacency is not taken into account;
* Heal discrete model: source TopoDS_Shape can contain problems, such as open-wire or self-intersections, introduced during design, exchange or modification of model. In addition, some problems like self-intersections can be introduced by roughly discretized edges. This stage is responsible for analysis of discrete model in order to detect and repair faced problems or refuse model’s part for further processing in case if problem cannot be solved;
* Preprocess discrete model: defines actions specific for implemented approach to be performed before meshing of faces. By default, iterates over model faces and checks consistency of existing triangulations. Cleans topological faces and its adjacent edges from polygonal data in case of inconsistency or marks face of discrete model as not required for computation;
* Discretize faces: represents core part performing mesh generation for particular face based on 2D discrete data related to processing face. Caches polygonal data associated with face’s edges in data model for further processing and stores generated mesh to TopoDS_Face;
* Postprocess discrete model: defines actions specific for implemented approach to be performed after meshing of faces. By default, stores polygonal data obtained on previous stage to TopoDS_Edge objects of source model.
Component is now spread over IMeshData, IMeshTools, BRepMeshData and BRepMesh units.
<!break>
1. Extend "tricheck" DRAW-command in order to find degenerated triangles.
2. Class BRepMesh_FastDiscret::Parameters has been declared as deprecated.
3. NURBS range splitter: do not split intervals without necessity. Intervals are split only in case if it is impossible to compute normals directly on intervals.
4. Default value of IMeshTools_Parameters::MinSize has been changed. New value is equal to 0.1*Deflection.
5. Correction of test scripts:
1) perf mesh bug27119: requested deflection is increased from 1e-6 to 1e-5 to keep reasonable performance (but still reproducing original issue)
2) bugs mesh bug26692_1, 2: make snapshot of triangulation instead of wireframe (irrelevant)
Correction in upgrade guide.

Standard_NullObject exception to skip invalid Edges.
Extended SelectBasics_PickResult structure by myObjPickedPnt field, which contained the value of the 3d point on the selected object.
Changed all Overlaps methods. Parameter theDepth replaced on object of the structure SelectBasics_PickResult. This approach will be able to add new fields to SelectBasics_PickResult structure without big changes in modules which contained Overlaps method.
Bnd_OBB constructor from Bnd_Box is fixed for VOID input.
DRAW command bounding command is adjusted:
- Support of old syntax 'bounding shape'is restored.
- Exception on VOID bounding box is avoided.
- Arguments are handled in case-insensitive way.
- Options -s, -perfmeter, and ability to set result as first argument are removed as redundant.
- Help is moved to command definition.

TKService dependency from TKShHealing has been dropped.
Methods SelectMgr_SelectableObject::GetHilightPresentation(), ::GetSelectPresentation() and ::UpdateClipping()
have been corrected to copy clipping planes of the object into highlighting and selection presentations.

- BRepGProp_MeshCinert computes the global properties of polylines represented by a set of points;
- BRepGProp_MeshProps computes the global properties of a surface mesh.
Existing tool BRepGProp now automatically uses new algorithm for triangulation-only faces.
By default, algorithm will use exact geometry objects (surfaces), when it is available (as before the patch);
this behavior can be switched by a new flag UseTriangulation, forcing usage of triangulation instead of exact geometry when both defined.
Image_Color - removed semibroken summ/difference operators.
