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.
License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast
Wrong license statements corrected in several files.
Copyright and license statements added in XSD and GLSL files.
Copyright year updated in some files.
Obsolete documentation files removed from DrawResources.
- OpenGl_Display - release GL resources correctly on closing views
- OpenGl_AspectFace, OpenGl_AspectText, OpenGl_AspectLine, OpenGl_AspectMarker - initialize OpenGl resources on demand, when context is available.
- Graphic3d_TextureRoot - use const modifier for GetId method to avoid asynchronous resource state at OpenGl.
- Do not call OpenGL functions if no active GL context has been left
- Reset thread's context before deletion for Mesa WNT
Introduce Point Sprites usage.
Graphic3d_Group - drop Marker(),MarkerSet() methods - markers should be drawn using AddPrimitiveArray.
Added new Draw Harness commands vcaps, vmarkerstest.
Structures Graphic3d_CView, Graphic3d_CStructure, Graphic3d_CGroup become classes and their definitions moved from InterfaceGraphic to Graphic3d.
Introduced new class OpenGl_Texture as replacement for OpenGl_ResourceTexture class and static functions in OpenGl_TextureBox.
Graphic3d_TextureRoot now no more communicate within Graphic3d_GraphicalDriver.
Instead class returns image through GetImage() method.
OpenGl_AspectFace - avoid possible NULL-dereference
OpenGl_Texture::Init() - check gluBuild2DMipmaps() return value
OpenGl_Texture - check GL_BGRA_EXT for compatibility
OpenGl_Texture - scale NPOT image when required
Added more description to Graphic3d_TextureRoot class
OpenGl_Texture - added missing break statement for ImgBGR32 case
OpenGl_Workspace::setTextureParams() - fixed local variable aFilterMin overrides visibility of early declared variable
OpenGl_Workspace::DisableTexture() - reset texture matrix
FTGL do not reset texture matrix and corrupt text could be rendered if custom texture has not identity texture matrix.
OpenGl_Resource was slightly corrected and OpenGl_Element was extended
with Release method to manage GPU resources.
OpenGl_PrimitiveArray now uses new OpenGl_VertexBuffer class (requires OpenGL 1.5+).
Strange workarounds for feedback mode were removed.
OpenGl_Context now provides access to shared GPU resources
and manages resources queue for delayed release
(replaces functionality of removed OpenGl_ResourceCleaner).
Loaded GL_ARB_texture_buffer_object and GL_ARB_draw_instanced extensions.
Global maps of views, workspaces and structures
were moved to OpenGl_GraphicDriver members.
UserDrawCallback() function moved to OpenGl_GraphicDriver methods.
Aspect_GraphicCallbackStruct now holds handle of OpenGl_Context
instead of system-dependent pointers to GL context definition.
New classes NCollection_Vec2, NCollection_Vec3 and NCollection_Vec4
implements interface to low-level data (points, vertices, colors) in GLSL-style.
Removed EnableVBO argument from vdrawparray Draw Harness command
Corrected compilation errors
Fixed wrong argument in Index VBO initialization
Fixed several cases of incorrect memory management in TKV3d
Visual3d_ViewManager::Remove()
Destroy structures before last view removed for correct GPU resources management.
Graphic3d_Structure::GraphicClear()
Remove groups to avoid usage of dead OpenGl_Group pointers.
V3d_View::Remove()
Fixed mistake in #0000280 patch.
Small correction
Fixed OCC280 test command
Replace removed view within created one in ViewerTest EventManager.
ViewerTest, do not create unused 3D view
In current design NIS_View always created and used for both - NIS objects and AIS objects.
myIsUpdated flag and Invalidate() method removed from OpenGl_Workspace class.
View redrawing is made unconditional.
V3d_View::Update() becomes deprecated and should be replaced with V3d_View::Redraw().
V3d_Viewer::Update() becomes deprecated and equivalent to Redraw()
