Including system OpenGL headers has been moved from OpenGl_GlFunctions.hxx to OpenGl_GlNative.hxx.
Added OpenGl_GlTypes.hxx providing basic OpenGL 1.1 types.
Wrappers of system OpenGL 1.1 / OpenGL ES 2.0 functions have been moved to OpenGl_GlFunctions.cxx.
Avoided usage of global OpenGL functions in OpenGl package outside of OpenGl_GlFunctions.cxx.
OpenGl_Buffer - added new class as a base for OpenGl_VertexBuffer, OpenGl_IndexBuffer, OpenGl_TextureBuffer.
OpenGl_TextureBufferArb has been renamed to OpenGl_TextureBuffer.
OpenGl_FrameBuffer - added initializers taking vec2i instead of (int,int) for dimensions.
Error messages in TKOpenGl package have been improved to format
GLenum values as string constants or hex values.
OpenGl_VertexBuffer::init() now logs a message with error details
instead of just returning Boolean flag.
Added OpenGl_Context::GetBufferSubData() implementing getBufferSubData() based on capabilities of various APIs.
Added OpenGl_VertexBuffer::GetSubData() similar to OpenGl_VertexBuffer::SubData().
- Provide DumpJson for geometrical, ocaf and visualization classes;
- Change depth parameter of DumpJson (constant is not obligate here)
- Introduce a new macro for transient objects to be called as the first row in DumpJson: OCCT_DUMP_TRANSIENT_CLASS_BEGIN. We need not put the class name in the macro, using get_type_name of Standard_Transient for it.
- change implementation of OCCT_DUMP_CLASS_BEGIN and OCCT_DUMP_TRANSIENT_CLASS_BEGIN. It is not an sentry more and it does not create a new hierarchy level. It appends a new row into the output stream: "className": <className>
- OCCT_DUMP_* does not require semicolon
- class header is included first in source files of TDataStd, TDocStd, TCAFDoc
Graphic3d_Buffer can be now optionally initialized as non-interleaved array of vertex attributes
and provides an interface to invalidate buffer sub-range tracked by OpenGl_PrimitiveArray.
Graphic3d_RenderingParams::ToShowStats - new option displaying rendering statistics.
OpenGl_FrameStats - new class for accumulating frame statistics.
OpenGl_Context::FrameStats() provides an access to the frame stats
used for currently rendered context.
OpenGl_View::Redraw() and OpenGl_View::RedrawImmediate()
resets counters within OpenGl_Context::FrameStats().
OpenGl_Layer::UpdateCulling() - simplified resetting of culling state for cullable structures.
FFP state management (light sources, matrices, clipping planes) has been
moved to OpenGl_ShaderManager for consistency with Programmable Pipeline.
OpenGl_Context::BindProgram() does not re-bind already active Program.
OpenGl_PrimitiveArray::Render() does not reset active Program at the end.
OpenGl_Context::ApplyModelViewMatrix() now checks if matrix differs
from already set one before modifying state in Shader Manager.
This allows avoing redundant state changes, matrix uploads onto GPU
and re-computation of inversed matrices.
NCollection_Mat4 has been extended with equality check operators for proper comparison.
OpenGl_ShaderManager - the tracking Material state has been added.
Removed unreachable states OPENGL_NS_RESMAT, OPENGL_NS_TEXTURE and OPENGL_NS_WHITEBACK.
Fixed resetting FFP material state after displaying GL_COLOR_ARRAY vertices;
the Material state within Shader Manager is now
invalidated within OpenGl_VertexBuffer::unbindFixedColor().
OpenGl_Workspace::ApplyAspectFace() - fixed invalidating Material State
when only Highlighting style is changing.
Inherit NCollection_Buffer from Standard_Transient, do not use incomplete NCollection_Handle.
OpenGl_Context, add methods ActiveProgram(),BindProgram()
to manage currently active GLSL program.
Add method ::ToUseVbo().
OpenGl_ShaderProgram, setup locations of pre-defined vertex attributes
occVertex, occNormal, occTexCoord, occColor before linkage.
Remove methods OpenGl_ShaderProgram::Bind(), ::BindWithVariables()
and ::Unbind() - OpenGl_Context::BindProgram() should be used instead.
Introduce class OpenGl_VertexBufferCompat, which emulates VBO
behavior on systems without VBO (compatibility with broken OpenGL drivers on Windows).
OpenGl_PrimitiveArray - use OpenGl_VertexBufferCompat when VBO is unavailable,
remove duplicated code. Use OpenGl_VertexBuffer::HasNormalAttribute()
method to activate lighting.
OpenGl_Text - use OpenGl_VertexBufferCompat, eliminate duplicated code.
Changes in OpenGl_VertexBuffer, drop methods BindFixed()/UnbindFixed().
Superseded by new methods BindAllAttributes()/UnbindAllAttributes()
which handle active GLSL program, when it is set.
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.
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.
Remove broken hasEdgeInfos.
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.
Graphic3d_Group - remove array or primitive arrays.
Introduce more universal method Graphic3d_Group::AddPrimitiveArray().
Fix warning
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.
