<h2>New Features</h2> |
<ul> |
<li>Intel i965 "broadwater" DRI driver |
|
<li>GL_APPLE_vertex_array_object - allows encapsulation of a set of vertex |
arrays in an object. |
|
<li>GL_EXT_texture_sRGB - non-linearly mapped texture formats |
|
<li>GL_EXT_gpu_program_parameters - addes a few new functions for setting |
multiple vertex/fragment program parameters with one call. |
<li>"engine" demo |
<li>updated fbdev driver and GLUT for fbdev (Sean D'Epagnier) |
<li>many updates to the DRI drivers |
</ul> |
|
<h2>Changes</h2> |
<ul> |
<li>The glVertexAttribARB functions no longer alias the conventional |
vertex attributes. |
<li>glxinfo program prints more info with -l option |
<li>GL_FRAGMENT_PROGRAM_NV and GL_FRAGMENT_PROGRAM_ARB are now |
compatible, in terms of glBindProgramARB() |
<li>The GL_ARB_vertex_program attribute <code>vertex.weight</code> is now |
accepted by the parser, even though the GL_ARB_vertex_blend and |
GL_EXT_vertex_weighting extensions aren't supported. |
Allows Warcraft to run. |
</ul> |
|
<h2>Bug fixes</h2> |
<ul> |
<li>fixed broken texture border handling for depth textures (bug 6498) |
<li>removed the test for duplicated framebuffer attachments, per |
version 117 of the GL_EXT_framebuffer_object specification |
<li>fixed a few render-to-texture bugs, including render to depth texture |
<li>clipping of lines against user-defined clip planes was broken (6512) |
<li>assembly language dispatch for SPARC was broken (bug 6484) |
<li>assorted compilation fixes on various Unix platforms (Dan Schikore) |
<li>glPopAttrib could restore an invalid value for GL_DRAW_BUFFER |
<li>assorted minor fixes for 16 and 32 bit/channel modes |
<li>fixed assorted bugs in texture compression paths |
<li>fixed indirect rendering vertex array crashes (bug 6863) |
<li>glDrawPixels GL_INDEX_OFFSET didn't always work |
<li>fixed convolution memory leak (bug 7077) |
<li>rectangular depth textures didn't work |
<li>invalid mode to glBegin didn't generate an error (bug 7142) |
<li>'normalized' parameter to glVertexAttribPointerARB didn't work |
<li>disable bogus GLX_SGI_video_sync extension in xlib driver |
<li>fixed R128 driver locking bug (Martijn van Oosterhout) |
<li>using evaluators with vertex programs caused crashes (bug 7564) |
<li>fragment.position wasn't set correctly for point/line primitives |
<li>fixed parser bug for scalar sources for GL_NV_fragment_program |
<li>max fragment program length was incorrectly 128, now 1024 |
<li>writes to result.depth in fragment programs weren't clamped to [0,1] |
<li>fixed potential dangling pointer bug in glBindProgram() |
<li>fixed some memory leaks (and potential crashes) in Xlib driver |
<li>fixed a number of build issues on HP-UX (Christopher Bell) |
<li>accum buffer didn't work with OSMesa interface |
</ul> |
|
|
<h2>Internal code changes</h2> |
|
<p> |
A number of Mesa program-related structs were renamed. |
For example <i>struct vertex_program</i> is now <i>struct gl_vertex_program</i>. |
All the effected drivers have been updated. |
</p> |
|
<p>Ian Romanick updated the GL API dispatch code in a number of ways. |
First, many old/unused extensions were removed. |
Second, the static entrypoints for some extensions were removed. |
This means GL function pointers will have to be used more often |
(e.g. use glXGetProcAddressARB()). |
</p> |
|
|
<h2>To Do (someday) items</h2> |
<ul> |
<li>Switch to freeglut |
<li>Increase MAX_DRAWBUFFERS |
<li>Fix linux-glide target/driver. |
<li>Fix lambda calculation for frag progs. |
</ul> |
|
