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.
D3DHost_FrameBuffer::BindBuffer() now implicitly detaches Depth+Stencil texture in case of driver failure.
D3DHost_View::d3dCreateRenderTarget() now does not request Depth+Stencil texture by default.
D3DHost_FrameBuffer now provides fallback code copying OpenGL FBO content into D3D surface (slow).
OpenGl_FrameBuffer::BufferDump() - FBO dump implementation has been moved from OpenGl_Workspace::BufferDump().
OpenGl_ShaderProgram::Initialize() - precision declarations have been moved
after the list of enabled extensions.
Declarations.glsl - the fragment shader outputs have been re-declared as array
for proper assignment of default locations (draw buffers).
OpenGl_FrameBuffer - GL_HALF_FLOAT is now used instead of GL_HALF_FLOAT_OES on OpenGL ES 3.2+.
OpenGl_Texture - fixed initialization of Image_Format_RGB32 image format on OpenGL ES 3.0+.
Weighted, Blended Order-Independent Transparency algorithm has been added rasterization pipeline.
In contrast to classical blending transparency it makes transparent objects look independent
from point of view. It also gives better depth occlusion when being used together with a weight factor
based on value of a GL depth buffer. The feature supports desktop OpenGL, OpenGL ES 3.0, ANGLE
and can be used together with MSAA on desktop GL.
To be used it require availability of:
1) Shaders pipeline.
2) Floating point color format for framebuffer (GL_ARB_color_buffer_float).
3) Multiple render targets (GL_ARB_draw_buffers).
Patch does not modify API and does not require application porting.
It adds new rendering options to Graphic3d_RenderingParams structure:
a) Transparency method from enumeration.
b) Scalar factor [0-1] controlling influence of a fragment's depth to its visibility.
Patch also simplifies processing of transparent objects for standard method:
rendering priority of transparent graphical structures is managed automatically,
therefore there is no need to care about it at application's side.
Graphic3d_Camera definition has been exended by optional Tile property (Graphic3d_CameraTile structure).
V3d_View::ToPixMap() now performs tiled dump when image size exceeds hardware limits.
OpenGl_View::Redraw() - fixed dump of immediate Z layers in no stereo and no MSAA case.
OpenGl_Context now tracks viewport values.
Draw Harness command vdump has been extended with new argument -tileSize.
OpenGl_Texture::Init2DMultisample() - new method to initialize multisampled texture.
Graphic3d_RenderingParams::NbMsaaSamples - add option defining MSAA samples number.
RayTracing will keep using FBO without MSAA, however it is possible to combine
MSAA for rasterization and FSAA for RayTracing.
OpenGl_FrameBuffer constructor has been changed to do not take arguments.
OpenGl_FrameBuffer::Init() method has been extended with mandatory parameters
defining Color and Depth attachment formats
and optional parameter defining number of MSAA parameters.
Draw Harness, add option -msaa to vrenderparams.
- Use two different FBOs for accumulating frames for left/right eye projection.
- Added equality checks to camera modification methods to avoid camera updates when performing identity operations.
OpenGl_Texture::Init() - initialize FBO textures with GL_TEXTURE_WRAP_ set to GL_CLAMP_TO_EDGE,
since some devices do not support GL_REPEAT (which is default) in such combination.
OpenGl_Font::createTexture() - define texture parameters explicitly.
OpenGl_FrameBuffer::Init() create Depth render buffer object instead of texture
on devices which do not support GL_DEPTH24_STENCIL8.
OpenGl_View::Render() - pass target FBO as parameter.
OpenGl_Context - revise Read/Write buffers management logic, taking into account FBOs.
Graphic3d_Camera::UpdateProjection() - setup LProjection and RProjection
the same as MProjection in case of Projection_MonoLeftEye/Projection_MonoRightEye
for API consistency.
OpenGl_FrameBuffer::InitWithRB() - add method to initialize FBO with Render Buffer Objects.
OpenGl_FrameBuffer::InitWrapper() - add new method to initialize FBO from currently bound in context.
Aspect_RenderingContext - define type explicitly to EAGLContext* / NSOpenGLContext* for ARC.
OpenGl_Window - allow initialization from alien context for OS X / iOS.
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.
Drop unused OpenGl_ArbVBO.
Replace OpenGl_ExtFBO with OpenGl_ArbFBO.
OpenGl_Context - reorganize GL functions management.
OpenGl_GlFunctions structure now stores pointers for all GL functions,
while inheritors specify functions subset using access levels.
Drop fields core12, core13, core14; replace extFBO by arbFBO.
OpenGl_ArbIns, OpenGl_ArbTBO - use GL3.1 core functions
instead of ARB extensions when available.
OpenGl_ArbFBO - provide complete list of functions
OpenGl_GlCore11 - fix misprint
OpenGl_Context.hxx - remove redundant declarations
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
