  64 Gallium3D is the codename for the new Mesa device driver architecture
  65 which is currently under development.
  66 A <a href="http://www.tungstengraphics.com/wiki/index.php/Gallium3D"
  67 target="_parent"> summary</a> of the architecture can be found on the
  68 Tungsten Graphics website.
  69 </p>
  70 <p>
  71 Gallium3D development is taking place on the <em>gallium-0.1</em> branch
  72 of the git repository.
  73 Currently, there's only a software-only driver and an Intel i915/945 driver
  74 but other drivers will be coming...

1104 <p>I'm pleased to announce that I've accepted a position with Precision Insight,
1105 Inc. effective October, 1999. I'll be leaving Avid Technology in September.</p>
1106 <p>I've been working on Mesa in my spare time for over five years. With Precision
1107 Insight I now have the opportunity to devote my full attention to advancing Mesa
1108 and OpenGL on Linux.</p>
1109 <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
1110 my work will continue to be open sourced and available to any other programmers who
1111 may want to contribute to it, or use it for other projects or platforms</p>
1112 <p>PS: I'm going to be traveling until Sep 6 and won't be reading email until then.</p>

1115 <p>Anonymous CVS access is back online so suck up all the bandwidth you can afford.
1116 Note that this is a new archive, so you will need to re-checkout the archive. That
1117 means don't <i>cvs update</i> from a previous download.</p>

1140 If you are into the quake scene, you may want to try this out, as it contains some
1141 optimizations specifically in the Q3A rendering path.

1148 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1149 US$10,000 to the Mesa project to support its continuing development.
1150 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1151 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1152
1153 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1154 improve performance on 3d hardware.  Thanks to Keith's work, many
1155 applications using Mesa 3.1 will see a dramatic performance increase
1156 over Mesa 3.0.  The donation will allow Keith to continue working on
1157 Mesa full time for some time to come.
1158

1160 information about id Software, Inc. see www.idsoftware.com.

1164 This donation from John/id is very generous.  Keith and I are very
1165 grateful.
