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

1110 xfree86 3.3.3.1, along with the <b>full source</b>, which includes GLX acceleration
1111 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>

1114 <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>.
1115 If you are into the quake scene, you may want to try this out, as it contains some
1116 optimizations specifically in the Q3A rendering path.

1123 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1124 US$10,000 to the Mesa project to support its continuing development.
1125 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1126 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1127
1128 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1129 improve performance on 3d hardware.  Thanks to Keith's work, many
1130 applications using Mesa 3.1 will see a dramatic performance increase
1131 over Mesa 3.0.  The donation will allow Keith to continue working on
1132 Mesa full time for some time to come.
1133
1134 For more information about Mesa see www.mesa3d.org.  For more
1135 information about id Software, Inc. see www.idsoftware.com.
