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

1100 <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>.
1101 If you are into the quake scene, you may want to try this out, as it contains some
1102 optimizations specifically in the Q3A rendering path.

1109 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1110 US$10,000 to the Mesa project to support its continuing development.
1111 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1112 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1113
1114 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1115 improve performance on 3d hardware.  Thanks to Keith's work, many
1116 applications using Mesa 3.1 will see a dramatic performance increase
1117 over Mesa 3.0.  The donation will allow Keith to continue working on
1118 Mesa full time for some time to come.
1119

1121 information about id Software, Inc. see www.idsoftware.com.

1126 grateful.
