 150 Gallium3D is the codename for the new Mesa device driver architecture
 151 which is currently under development.
 152 A <a href="http://wiki.freedesktop.org/wiki/Software/gallium"
 153 target="_parent"> summary</a> of the architecture can be found on the
 154 Tungsten Graphics website.
 155 </p>
 156 <p>
 157 Gallium3D development is taking place on the <em>gallium-0.1</em> branch
 158 of the git repository.
 159 Currently, there's only a software-only driver and an Intel i915/945 driver

1185 that seem to be... yes, I've just received confirmation from the beta center, they
1186 are indeed the <b>THIRD</b> beta release of Mesa 3.1! Happy Days. Happy Days. Thanks
1187 Keith Whitwell for preparing these for us during Brian's absence.</p>

1190 <p>I'm pleased to announce that I've accepted a position with Precision Insight,
1191 Inc. effective October, 1999. I'll be leaving Avid Technology in September.</p>
1192 <p>I've been working on Mesa in my spare time for over five years. With Precision
1193 Insight I now have the opportunity to devote my full attention to advancing Mesa
1194 and OpenGL on Linux.</p>
1195 <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
1196 my work will continue to be open sourced and available to any other programmers who
1197 may want to contribute to it, or use it for other projects or platforms</p>
1198 <p>PS: I'm going to be traveling until Sep 6 and won't be reading email until then.</p>

1201 <p>Anonymous CVS access is back online so suck up all the bandwidth you can afford.
1202 Note that this is a new archive, so you will need to re-checkout the archive. That
1203 means don't <i>cvs update</i> from a previous download.</p>

1226 If you are into the quake scene, you may want to try this out, as it contains some
1227 optimizations specifically in the Q3A rendering path.

1234 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1235 US$10,000 to the Mesa project to support its continuing development.
1236 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1237 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1238
1239 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1240 improve performance on 3d hardware.  Thanks to Keith's work, many
1241 applications using Mesa 3.1 will see a dramatic performance increase
1242 over Mesa 3.0.  The donation will allow Keith to continue working on
1243 Mesa full time for some time to come.
1244

1246 information about id Software, Inc. see www.idsoftware.com.
