OpenGl_Element destruction and resource deallocation methods now accept
a pointer to OpenGl_Context instead of a handle to avoid double deletion
of the context.
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.
Graphic3d_Group is now abstract class and should be instantiated
using Graphic3d_Structure::NewGroup() method.
Graphic3d_CGroup has been removed.
The groups list is no more duplicated within Graphic3d_Structure and OpenGl_Structure.
Removed unused/duplicated fields from Graphic3d_Group.
Prs3d_Presentation - remove redundnant field myCurrentGroup.
PrsMgr_Presentation3d::Erase(), ::Clear() - avoid possible NULL dereference.
OpenGl_GraphicDriver/Graphic3d_GraphicDriver - group management methods have been removed
(moved to Graphic3d_CStructure and Graphic3d_Group interfaces).
Graphic3d_Group::GroupPrimitivesAspect() - copy IsEmission flag
Fix wrong iterator
Fix compilation issues
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
Graphical clipping:
- Use "Graphic3d_ClipPlane" to defined clipping for PrsMgr_PresentableObject (local clipping), for V3d_View (global clipping).
Get rid of old implementations:
- Remove Visual3d_ClipPlane.
- Port V3d_Plane to Graphic3d_ClipPlane core.
Selection Sensitives:
- Port "Matches" method to add full set of arguments (SelectBasics_PickArgs), including min-max depth coming from selector.
- Get rid of transient data for pair Matches -> ComputeDepth.
- Extend SelectMgr_ViewerSelector::LoadResult to work with local clipping, add virtual callbacks to compute globa/local depth clipping for picking.
Capping rendering algorithm:
- Recursive rendering algorithm for OpenGl_Groups.
- Introduced Rendering filter for groups.
Clipping plane management in TKOpenGl:
- Added OpenGl_ClippingState to OpenGl_Context.
DRAWEXE commands:
- Ported "vclipplane" command for new approach.
- Added "vsettexturemode" command for changing texture details in views (enable / disable textures).
Correct DownCast syntax (compilation error)
Fix new compiler warnings
tests/bugs/vis/bug22906 migrated to the new vclipplane syntax
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.
