  32 Gallium3D is the codename for the new Mesa device driver architecture
  33 which is currently under development.
  34 A <a href="http://www.tungstengraphics.com/wiki/index.php/Gallium3D"
  35 target="_parent"> summary</a> of the architecture can be found on the
  36 Tungsten Graphics website.
  37 </p>
  38 <p>
  39 Gallium3D development is taking place on the <em>gallium-0.1</em> branch
  40 of the git repository.
  41 Currently, there's only a software-only driver and an Intel i915/945 driver
  42 but other drivers will be coming...

1102 <p><a href="http://www.nvidia.com/">nVidia</a> has released some Linux binaries for
1103 xfree86 3.3.3.1, along with the <b>full source</b>, which includes GLX acceleration
1104 based on Mesa 3.0. They can be downloaded from <a href="http://www.nvidia.com/Products.nsf/htmlmedia/software_drivers.html">http://www.nvidia.com/Products.nsf/htmlmedia/software_drivers.html</a>.</p>

1107 <p>Beta 2 of Mesa 3.1 has been make available at <a href="ftp://ftp.mesa3d.org/mesa/beta/">ftp://ftp.mesa3d.org/mesa/beta/</a>.
1108 If you are into the quake scene, you may want to try this out, as it contains some
1109 optimizations specifically in the Q3A rendering path.

1112 <p>For those interested in the integration of Mesa into XFree86 4.0, Precision Insight
1113 has posted their lowlevel design documents at http://www.precisioninsight.com.</p>

1116 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1117 US$10,000 to the Mesa project to support its continuing development.
1118 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1119 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1120
1121 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1122 improve performance on 3d hardware.  Thanks to Keith's work, many
1123 applications using Mesa 3.1 will see a dramatic performance increase
1124 over Mesa 3.0.  The donation will allow Keith to continue working on
1125 Mesa full time for some time to come.
1126
1127 For more information about Mesa see www.mesa3d.org.  For more
1128 information about id Software, Inc. see www.idsoftware.com.
