<h2>New Features</h2>
|
||
|
|
<ul>
|
||
|
|
<li>OpenGL Shading language support
|
||
|
|
<br>
|
||
|
|
This includes the GL_ARB_shader_objects, GL_ARB_shading_language_100,
|
||
|
|
GL_ARB_vertex_shader and GL_ARB_fragment_shader extensions. Most of
|
||
|
|
the work was done by Michal Krol.
|
||
|
|
There's probably a fair number of bugs since this is a pretty large,
|
||
|
|
complicated body of code.
|
||
|
|
<br>
|
||
|
|
The OpenGL 2.0 interface to these features will be implemented in a
|
||
|
|
future version of Mesa,
|
||
|
|
|
||
|
|
<li>GL_EXT_timer_query
|
||
|
|
<br>
|
||
|
|
Used to measure the time of OpenGL operations at high precision.
|
||
|
|
Only supported in the software/Xlib driver at this time.
|
||
|
|
|
||
|
|
<li>GL_EXT_packed_depth_stencil
|
||
|
|
<br>
|
||
|
|
Defines a new GL_DEPTH_STENCIL_EXT pixel format.
|
||
|
|
|
||
|
|
<li>GL_EXT_framebuffer_blit
|
||
|
|
<br>
|
||
|
|
A simplified glCopyPixels-like feature for copying pixel rectangles.
|
||
|
|
|
||
|
|
<li>GL_ARB_half_float_pixel
|
||
|
|
<br>
|
||
|
|
Adds a new half-precision floating point format for image transfers,
|
||
|
|
such as for glDrawPixels, glReadPixels, glTexImage, etc.
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<h2>Changes</h2>
|
||
|
|
<ul>
|
||
|
|
<li>removed GL_HP_occlusion_test (use GL_ARB_occlusion_query instead)
|
||
|
|
<li>removed GL_SGIX/SGIS_pixel_texture extensions
|
||
|
|
</ul>
|
||
|
|
<h2>Bug fixes</h2>
|
||
|
|
<ul>
|
||
|
|
<li>fixed glxcontextmodes.c datatype problem (bug 5835)
|
||
|
|
<li>fixed aix-gcc build/install bugs (bug 5874)
|
||
|
|
<li>fixed some bugs in texture env program generation
|
||
|
|
<li>glXCopyContext() didn't handle texture object bindings properly
|
||
|
|
<li>glXCopyContext() didn't copy all lighting state
|
||
|
|
<li>fixed FreeBSD config (Pedro Giffuni)
|
||
|
|
<li>fixed some minor framebuffer object bugs
|
||
|
|
<li>replaced dprintf() with _glu_printf() in GLU (bug 6244)
|
||
|
|
<li>fixed a number of thread safety bugs/regressions
|
||
|
|
<li>fixed a number of GLU tesselator bugs (John Shell, bug 6339)
|
||
|
|
<li>paletted texturing was broken w/ floating point palettes (K. Schultz)
|
||
|
|
<li>lots of assorted framebuffer object bug fixes
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
|
||
|
|
<h2>Known Issues</h2>
|
||
|
|
<ul>
|
||
|
|
<li>Rendering to depth textures will not work. Rendering to GL_DEPTH_STENCIL
|
||
|
|
textures should work.
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
|
||
|
|
<h2>Driver Interface Changes</h2>
|
||
|
|
<ul>
|
||
|
|
<li>Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by
|
||
|
|
the two-sided versions: Driver.Stencil*Separate().
|
||
|
|
<li>Render-to-texture: The functions for rendering to textures have changed.
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
|
||
|
|
<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>
