Drop Graphic3d_GraphicDriver::Begin() and ::End() methods.
Initialization is performed within driver constructor.
Drop dummy argument for Graphic3d_GraphicDriver constructor with library name.
Display connection now should be set instead
Drop Graphic3d::InitGraphicDriver() function and Graphic3d.hxx header.
Application code should explicitly link against TKOpenGl toolkit and instantiate OpenGl_GraphicDriver class.
Drop MetaGraphicDriverFactory implementation within TKOpenGl.
Aspect_GenId::Available(), include size of the queue with recently freed identifiers
Aspect_GenId.cxx - remove tabulation symbols
Test cases for issue CR25052
OpenGl_GraphicDriver::Redraw() - do not recompute structures more than required
OpenGl_Workspace::Raytrace() - bind proper FBO before clearing it
Visual3d_View::Redraw() - perform automatic 2nd redraw on device lost
Implement SAT intersection tests and frustum culling algorithm using BVH trees.
New Draw command vfrustumculling to manage frustum culling.
Add test cases bugs/vis/bug24307_1 and bugs/vis/bug24307_2.
Remove CALL_DEF_BOUNDBOX and CALL_DEF_BOUNDS.
StdPrs_ShadedShape, add flag theToExploreSolids to method ::Add().
Previously the tool collected triagnulations from all Faces into single graphic group.
The automated algorithm for back-face culling activation has to disable culling
when within closed Solids single Compound contains also open Shells.
Now tool is able to optionally (enabled by default) split these two categories of primitives
into dedicated groups with independent back-face culling settings.
In addition, this closed flag is now stored in Graphic3d_Group::myIsClosed which allows
capping algorithm OpenGl_CappingAlgo to automatically filter improper groups.
Refraction index passed to raytrace shader.
For transparent objects implemented ray refraction according to refraction index.
Transparent materials modified to look better with refractions.
Improve consistency and visual appearance of predefined OCCT materials in various rendering modes, including ray-tracing:
- Increase the specular exponents (shininesses) for metallic surfaces: Brass, Bronze, Copper, Gold, Pewter, Silver, Steel, Chrome, Aluminum.
- Revise specular colors for metals: Copper, Gold, Aluminum, Silver (according to "Real-Time Rendering, 3rd Edition", AK Peters 2008).
- Increase diffuse reflection of metals: Silver, Aluminum, Chrome (to make them brighter in OpenGL mode).
- Extend Material definition by Refraction Index.
Advanced rendering methods based on shaders or ray-tracing can utilize it to produce refraction effects.
In addition:
- Introduce three translucent materials: Water, Glass, and Diamond.
- Add Charcoal for modeling dark diffuse surfaces.
Add new TCL-based sample (materials.tcl) and test case (tests/v3d/materials/bug24855).
If specific layer setting is not enabled, default value extracted from current OpenGl state will be used.
Default value fix.
Updated test case bugs/vis/bug24867
Linux warning fixed.
Generic class TCollection_Stack removed (along with TCollection_StackIterator and TCollection_StackNode).
Code using TCollection_Stack changed to equivalent use of TCollection_List (replacing Push -> Prepend, Top -> First, Pop -> RemoveFirst).
Generic "TCollection_Queue" class removed (along with "TCollection_QueueNode" and three instantiations in TColStd). Template class TCollection_Queue removed.
The code using queue classes converted to use lists for the same purpose (replacing Push -> Append, Front -> First, Pop -> RemoveFirst). In OpenGl_Context, list is used as stack instead of queue, for it looks more natural for release of resources (last allocated - first released).
Redesign Graphic3d_ArrayOfPrimitives
Store vertices data in buffer objects managed using smart-pointers
- no more low-level memory corruption by memory releasing after VBO creation.

Interleave vertex attributes (position, color, normal, uv) in single buffer.
Remove from Graphic3d_ArrayOfPrimitives methods ::Orientate().
Remove structures Graphic3d_PrimitiveArray, CALL_DEF_PARRAY.
Add support for 2D vertex arrays.

Removed unused/duplicated fields from Graphic3d_Group.

::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.

instead of ARB extensions when available.
OpenGl_ArbFBO - provide complete list of functions
OpenGl_GlCore11 - fix misprint
OpenGl_Context.hxx - remove redundant declarations
From now on, the panning behavior of V3d_View completely corresponds to equal operations with camera. There is no more confusing "Center" property and "ProjectionShift" which were used to introduce composite panning, while respecting view referential points: At, Eye unchanged. The V3d_View::FitAll approach has been rewritten to do "fit all" geometrically, operating with frustum, to make it working for both orthographic and perspective projections.
1) Getting rid of ProjectionShift and Center property:
- Removed ProjectionShift property of Graphic3d_Camera.
- Removed confusing Center property of V3d_View (related to projection shift).
- Removed redundant code related to the Center property of V3d_View.
- Removed WindowLimit method of Graphic3d_Camera - no more used.
2) Improvements of fit all and selector:
- Improved FitAll operation of V3d_View and reused it in NIS_View - the perspective projection is now handled correctly.
- Revised code of Select3D_Projector class - can be defined with any given projection and model-view matrices.
- Modified StdSelect_ViewerSelector3d and ensured that panning, zooming and going into the view do not lead to unwanted re-projection of sensitives. The handling of perspective selection is revised.
- Take into account graphical boundaries of infinite structure on ZFitAll.
3) Improvements of camera:
- Introduced new z range scale parameter for V3d_View::AutoZFit. See, V3d_View::AutoZFitMode.
- Allow negative ZNear, ZFar for orthographic camera to avoid clipping of viewed model.
- Moved camera ZNear, ZFar validity checks to V3d_View level.
- Use more meaningful Standard_ShortReal relative precision for ZNear, ZFar ranges computed by ZFitAll.
- Use Standard_Real type for camera projection and orientation matrices.
- Extended camera to generate both Standard_Real and Standard_ShortReal transformation matrices using the same matrix evaluation methods and converted input parameters.
