 137 Gallium3D is the codename for the new Mesa device driver architecture
 138 which is currently under development.
 139 A <a href="http://wiki.freedesktop.org/wiki/Software/gallium"
 140 target="_parent"> summary</a> of the architecture can be found on the
 141 Tungsten Graphics website.

 143 <p>
 144 Gallium3D development is taking place on the <em>gallium-0.1</em> branch
 145 of the git repository.
 146 Currently, there's only a software-only driver and an Intel i915/945 driver
 147 but other drivers will be coming...

1170 <p>There appear to be two new files on the ftp site, <a href="ftp://ftp.mesa3d.org/mesa/beta/MesaLib-3.1beta3.tar.gz">MesaLib-3.1beta3.tar.gz</a>
1171 and <a href="ftp://ftp.mesa3d.org/mesa/beta/MesaDemos-3.1beta3.tar.gz">MesaDemos-3.1beta3.tar.gz</a>,
1172 that seem to be... yes, I've just received confirmation from the beta center, they
1173 are indeed the <b>THIRD</b> beta release of Mesa 3.1! Happy Days. Happy Days. Thanks
1174 Keith Whitwell for preparing these for us during Brian's absence.</p>

1177 <p>I'm pleased to announce that I've accepted a position with Precision Insight,
1178 Inc. effective October, 1999. I'll be leaving Avid Technology in September.</p>
1179 <p>I've been working on Mesa in my spare time for over five years. With Precision
1180 Insight I now have the opportunity to devote my full attention to advancing Mesa
1181 and OpenGL on Linux.</p>
1182 <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
1183 my work will continue to be open sourced and available to any other programmers who
1184 may want to contribute to it, or use it for other projects or platforms</p>
1185 <p>PS: I'm going to be traveling until Sep 6 and won't be reading email until then.</p>

1188 <p>Anonymous CVS access is back online so suck up all the bandwidth you can afford.
1189 Note that this is a new archive, so you will need to re-checkout the archive. That
1190 means don't <i>cvs update</i> from a previous download.</p>

1213 If you are into the quake scene, you may want to try this out, as it contains some
1214 optimizations specifically in the Q3A rendering path.

1221 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1222 US$10,000 to the Mesa project to support its continuing development.
1223 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1224 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1225
1226 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1227 improve performance on 3d hardware.  Thanks to Keith's work, many
1228 applications using Mesa 3.1 will see a dramatic performance increase
1229 over Mesa 3.0.  The donation will allow Keith to continue working on
1230 Mesa full time for some time to come.
1231

1233 information about id Software, Inc. see www.idsoftware.com.

1237 This donation from John/id is very generous.  Keith and I are very
1238 grateful.
