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> <h2>Driver Status</h2> <pre> Driver Status ---------------------- ---------------------- DRI drivers varies with the driver XMesa/GLX (on Xlib) implements OpenGL 1.5 OSMesa (off-screen) implements OpenGL 1.5 Glide (3dfx Voodoo1/2) implements OpenGL 1.3 SVGA implements OpenGL 1.3 Wind River UGL implements OpenGL 1.3 Windows/Win32 implements OpenGL 1.5 DJGPP implements OpenGL 1.5 GGI implements OpenGL 1.3 BeOS implements OpenGL 1.5 Allegro needs updating D3D needs updating </pre> </body> </html>
