| 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. |
