- AIS_InteractiveContext - create new dummy class field to have an empty TopoDS_Shape object.
- AIS_Point, PrsMgr_PresentableObject - rename static variables to local function variables.
- AIS_Shape, SelectMgr_SelectableObject - remove unused static variables.
- Graphic3d_MaterialAspect, V3d_Viewer - make global static variables as constant.
- V3d_View - move global variable zRotation to class field.
- Move a variable theCurrentSelection as a field of AIS_InteractiveContext and AIS_LocalContext classes. Multiple selection is not used now, so each Context have an own selection.
- Move myStructGenId from Graphic3d_StructureManager to Graphic3d_GraphicDriver for identifying the structures in the driver.
- Move default variable (no shading light) from static value to the class field of OpenGL_View.
Porting note:
- Static methods of AIS_Selection is not used now. Methods of
AIS_InteractiveContext::InitSelected(),::MoreSelected(),::NextSelected()
should be used instead of static methods of AIS_Selection.
Expose interface of OpenGl_View (OpenGL graphics rendering methods) to client code
and collecting all high-level API methods of application views in V3d_View class.
1) Exposing interface of OpenGl_View:
The OpenGl_View inherits from new class Graphic3d_CView.
Graphic3d_CView is an interface class that declares abstract methods for managing displayed structures,
display properties and a base layer code that implements computation
and management of HLR (or more broadly speaking view-depended) structures.
In new implementation it takes place of eliminated Visual3d_View.
As before the instance of Graphic3d_CView is still completely managed by V3d_View classes.
It can be accessed through V3d_View interface but normally this should not be required as all its methods are completely wrapped.
In more details, a concrete specialization of Graphic3d_CView is created and returned by graphical driver on request.
Right after creation the views is directly used for setting rendering properties and adding graphical structures to be displayed.
The rendering of graphics is possible after mapping a window and activating the view.
The direct setting of properties makes obsolete usage of intermediate structures with display parameter
like Visual3d_ContextView and etc (the whole package of Visual3d become redundant).
2) Collecting all high-level API methods of application views in V3d package:
The patch includes elimination of Visual3d layer.
All of its methods that could be previously used by application are now exposed and should be accessed on the level of V3d entities.
- Introduced new class Graphic3d_CView.
This is a base class for render views.
Made possible to specialize concrete instances of the class by graphical driver.
- Moved all methods managing rendering views into interface of Graphic3d_CView.
The corresponding methods were removed from interface of graphical driver.
3) Eliminated Visual3d package:
- Logic of managing display of structures was put from Visual3d_ViewManager into Graphic3d_StructureManager.
- Removed Visual3d_View class. Logic of managing computed structures was put into base layer of Graphi3d_CView.
- Removed all intermediate structures for storing view parameters e.g. Visual3d_ContextView.
All settings are kept by instances of Graphic3d_CView
- Removed Visual3d_Light intermediate class.
All light properties are still stored in Graphic3d_CLight structure.
The structure is directly access by instance of V3d_Light classes.
- Moved all needed enumerations into Graphic3d package.
4) Update package D3DHost to new changes.
5) Update code of OCCT samples to new changes.
- picked or selected objects are now highlighted via owners instead of interactive objects;
- support methods for owners were added to AIS_InteractiveContext;
- dynamically highlighted owners are now displayed in immediate mode;
- selection without opening of local context is enabled by default;
- added "-local" key to vselmode command to enable selection in local context;
- selection filters are now completely supported in AIS_InteractiveContext;
- the idea of differencing of selected items onto current (in interactive context) and selected (local selection) was eliminated;
- all calls to "current" were replaced by calls to "selected" in terms of future local context removal;
- AIS_InteractiveObject::mySelectionMode was removed;
- now each selectable object can define own selection mode for "global" selection of the whole object;
- whole object selection mode is 0 by default for all standard interactive objects;
- immediate structures are now added to topmost and top layer lists;
- added support of drawing immediate structures in different layers;
- unused code for immediate mode was removed;
- vfeedback and vexport commands now produce correct output for raytrace mode.
Automatic upgrade of OCCT code by command "occt_upgrade . -nocdl":
- WOK-generated header files from inc and sources from drv are moved to src
- CDL files removed
- All packages are converted to nocdlpack
Missing headers added; includes of headers "Handle_...hxx" removed.
Misuses of macro Handle() and its use in typedefs corrected.
Alias classes Profile and Option are removed from IFSelect; ones defined in MoniTool are used directly.
Removed header files defining only Handle classes (except Image_PixMap_Handle.hxx)
Classes SelectMgr_BaseFrustum and now inherit Standard_Transient and can be manipulated by Handle (not NCollection_Handle)
Fixed reference-type local variable pointing to temporary object
Use of handle in conditional expressions and comparisons to NULL are replaced by call to method IsNull()
Redesign of selection mechanism:
- implemented 3-level BVH tree for selection;
- selection now calculates in 3D space;
- intersection tests were moved to SelectMgr_BaseFrustum descendants;
- removed .cdl files in Select3D and .cdl related to selection in MeshVS;
- SelectMgr_ViewerSelectors are now shared between local and global contexts;
- transformations of sensitive entities are now stored in SelectMgr_SelectableObject only. Sensitive entities are independent from transformations, it is applied to SelectMgr_SelectingVolumeManager instance only;
- connected and multiple connected interactive objects are now represented by their child objects only for SelectMgr_SelectionManager;
- if interactive object has child objects, they will be stored as separate objects in SelectMgr_SelectionManager now.
- test cases bugs/vis/bug24623_1, bug24623_2, bug24623_3, bug24623_4 to test performance and memory issues.
Macros ending on "DEB" are replaced by OCCT_DEBUG across OCCT code; new macros described in documentation.
Macros starting with DEB are changed to start with "OCCT_DEBUG_".
Some code cleaned.
Remove unused flag "DoubleBuf".
Remove Visual3d_TransientManager "class" (functionality moved to PrsMgr_PresentationManager).
Remove unused "Add" immediate mode.
V3d_View class - remove methods ::TransientManagerBeginDraw(), ::TransientManagerClearDraw(), ::TransientManagerBeginAddDraw().

Mark PrsMgr_PresentationManager3d as alias to PrsMgr_PresentationManager to simplify porting.
Prs3d_Presentation - remove unused field myStruct.
Prs3d_PresentationShadow - shadow link to existing presentation with custom attributes.
Graphic3d_Structure::Highlight() - do not register undisplayed structure in structure manager.
AIS_InteractiveContext, AIS_LocalContext add flag to prevent view update into methods
::MoveTo(), ::HilightNextDetected(), ::HilightPreviousDetected()
to allow update of customized immediate structures before redraw but after ::MoveTo().
Remove unused method AIS_InteractiveContext::Drag().
StdSelect_ViewerSelector3d do not user immediate mode in methods
::DisplayAreas(), ::ClearAreas(), ::ClearSensitive(), ::DisplaySensitive(),
GridEcho - update value in StdSelect_ViewerSelector3d::Pick() instead of V3d_View::Compute().
Do not use global variable for GridEcho vertex.
Redraw immediate mode not within GridEcho but at AIS_InteractiveContext, AIS_LocalContext layer.
V3d_View::ToPixMap() - disable autoupdate during FitAll.
Avoid Redraw() into FBO without ImmediateModeDrawToFront flag.
PrsMgr_PresentationManager stores list of temporary immediate presentations,
automatically cleared within BeginImmediateMode() call.
Methods with ambiguous names have been renamed
(new names now consistent with pre-existed method names in AIS_LocalContext class):
- BeginDraw -> BeginImmediateDraw
- EndDraw -> EndImmediateDraw
Remove now useless Remove() method (and ImmediateRemove() in AIS).
Visual3d_View now stores map of displayed immediate presentations.
ViewerTest_EventManager - eliminate double redraw in selection methods.
