| <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> |
