<h2>Shared library numbering</h2>
|
||
|
|
<p>
|
||
|
|
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).
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
Other OpenGL vendors name their OpenGL 2.x libraries libGL.so.1.0.xxxxx
|
||
|
|
for the same reason.
|
||
|
|
</p>

||

<h2>New features</h2>
|
||
|
|
<ul>
|
||
|
|
<li>OpenGL 2.0 and 2.1 API support.
|
||
|
|
<li>Entirely new Shading Language code generator. See the
|
||
|
|
<a href="shading.html">Shading Language</a> page for more information.
|
||
|
|
<li>Much faster software execution of vertex, fragment shaders.
|
||
|
|
<li>New vertex buffer object (vbo) infrastructure
|
||
|
|
<li>Updated glext.h file (version 39)
|
||
|
|
<li>Updated glxext.h file (version 19)
|
||
|
|
<li>GL_MAX_DRAWBUFFERS is now 4 (software rendering) so
|
||
|
|
"multiple render targets" are really supported.
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<h2>Bug fixes</h2>
|
||
|
|
<ul>
|
||
|
|
<li>Fog was errantly applied when a fragment shader was enabled (bug 9346)
|
||
|
|
<li>glPush/PopClientAttrib didn't handle VBO bindings correctly (bug 9445)
|
||
|
|
<li>With 32-bit Z buffer, the fragment Z of lines and points was sometimes wrong.
|
||
|
|
<li>GL_POST_CONVOLUTION_ALPHA_BIAS/SCALE was broken.
|
||
|
|
<li>1D convolution state could effect 2D image transfers
|
||
|
|
<li>Overlapping glCopyPixels with negative Y zoom didn't work (bug 10521)
|
||
|
|
<li>Fixed a number of framebuffer/renderbuffer reference counting bugs
|
||
|
|
<li>Fixed a few bugs in software-emulated alpha planes
|
||
|
|
<li>Assorted minor bug fixes in glCopy/DrawPixels, glPixelZoom, etc.
|
||
|
|
<li>Assorted DRI driver bug fixes.
|
||
|
|
<li>Fixed a number of bugs that prevented "depth-peeling" rendering from working.
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
|
||
|
|
<h2>Internal code changes</h2>
|
||
|
|
<ul>
|
||
|
|
<li>Old array_cache module replaced by new vbo module. All geometry
|
||
|
|
rendering is now cast in the form of vertex buffer objects.
|
||
|
|
<li>Massive changes to the Shading Language compiler and related state.
|
||
|
|
<li>Vertex/fragment shaders are compiled into GPU instructions and
|
||
|
|
programs very similar to GL_ARB_vertex/fragment_program.
|
||
|
|
<li>Vertex and fragment programs are executed with the same code now.
|
||
|
|
<li>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.
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
|
||
|
|
<h2>To Do (someday) items</h2>
|
||
|
|
<ul>
|
||
|
|
<li>Switch to freeglut
|
||
|
|
<li>Fix linux-glide target/driver.
|
||
|
|
<li>Improved lambda and derivative calculation for frag progs.
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
|
||
|
|
