Graphic3d_AspectFillArea3d now stores array of textures.
Graphic3d_TextureParams stores texture unit for mapping texture.
OpenGl_Context::BindTextures() - context now manages the set of active textures.
Related code has been removed from OpenGl_Workspace.
OpenGl_Sampler has been extended to hold texture parameters structure.
OpenGl_Texture now holds OpenGl_Sampler instance as class field.
OpenGl_Texture inherits new class OpenGl_NamedResource and holds
texture identifier used for sharing resource in OpenGl_Context.
OpenGl_RaytraceGeometry now creates bindless textures taking
Sampler object directly from OpenGl_Texture.
OpenGl_Context::BindTextures() automatically recreates immutable
Sampler Object on texture parameters change.
Declared new structure OpenGl_ArbSamplerObject for platform-neutral
usage of related functionality.
Related functions are now loaded within OpenGL ES 3.0+.
Declarations.glsl - occActiveSampler has been renamed to occSampler0
with aliases occSamplerBaseColor (main) and occActiveSampler (for compatibility).
Additional texture samplers should be declared explicitly
within specific GLSL program as occSampler1, occSampler2, etc.
AIS_Shape and AIS_ColoredShape now computes Shaded presentation
with UV coordinates if texture mapping is enabled in Drawer.
vshaderprog now accepts Shader source code as parameter.
All variants of Init function of OpenGl_VertexBuffer are now also supported by OpenGl_TextureBufferArb.
Missing texture formats added to OpenGl_GlFunctions.hxx.
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.
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_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.
