Shared library numbering
|
|
------------------------
|
|
|
|
Mesa 6.5.3 supports the OpenGL 2.0/2.1 API. However, the (unix) shared
|
|
library version is still 1.5 (i.e. libGL.so.1.5.xxxxxx). Bumping the
|
|
shared library version to 2.x would cause linking problems with existing
|
|
OpenGL applications. Since OpenGL 2.x is backward compatible with OpenGL
|
|
1.x the shared library version number doesn't have to be incremented
|
|
(which would indicate an incompatible ABI).
|
|
|
|
Other OpenGL vendors name their OpenGL 2.x libraries libGL.so.1.0.xxxxx
|
|
for the same reason.
|
|
|
|
New features
|
|
------------
|
|
|
|
- OpenGL 2.0 and 2.1 API support.
|
|
- Entirely new Shading Language code generator. See the :doc:`Shading
|
|
Language <../shading>` page for more information.
|
|
- Much faster software execution of vertex, fragment shaders.
|
|
- New vertex buffer object (vbo) infrastructure
|
|
- Updated glext.h file (version 39)
|
|
- Updated glxext.h file (version 19)
|
|
- GL_MAX_DRAWBUFFERS is now 4 (software rendering) so "multiple render
|
|
targets" are really supported.
|
|
|
|
Bug fixes
|
|
---------
|
|
|
|
- Fog was errantly applied when a fragment shader was enabled (bug
|
|
9346)
|
|
- glPush/PopClientAttrib didn't handle VBO bindings correctly (bug
|
|
9445)
|
|
- With 32-bit Z buffer, the fragment Z of lines and points was
|
|
sometimes wrong.
|
|
- GL_POST_CONVOLUTION_ALPHA_BIAS/SCALE was broken.
|
|
- 1D convolution state could effect 2D image transfers
|
|
- Overlapping glCopyPixels with negative Y zoom didn't work (bug 10521)
|
|
- Fixed a number of framebuffer/renderbuffer reference counting bugs
|
|
- Fixed a few bugs in software-emulated alpha planes
|
|
- Assorted minor bug fixes in glCopy/DrawPixels, glPixelZoom, etc.
|
|
- Assorted DRI driver bug fixes.
|
|
- Fixed a number of bugs that prevented "depth-peeling" rendering from
|
|
working.
|
|
|
|
Internal code changes
|
|
---------------------
|
|
|
|
- Old array_cache module replaced by new vbo module. All geometry
|
|
rendering is now cast in the form of vertex buffer objects.
|
|
- Massive changes to the Shading Language compiler and related state.
|
|
- Vertex/fragment shaders are compiled into GPU instructions and
|
|
programs very similar to GL_ARB_vertex/fragment_program.
|
|
- Vertex and fragment programs are executed with the same code now.
|
|
- The SSE-optimized vertex program path has been removed since it
|
|
didn't support more than 12 temp registers, didn't support
|
|
branching/looping, etc.
|
|
|
|
To Do (someday) items
|
|
---------------------
|
|
|
|
- Switch to freeglut
|
|
- Fix linux-glide target/driver.
|
|
- Improved lambda and derivative calculation for frag progs.
|
