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

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

1166 <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>
1167 and <a href="ftp://ftp.mesa3d.org/mesa/beta/MesaDemos-3.1beta3.tar.gz">MesaDemos-3.1beta3.tar.gz</a>,
1168 that seem to be... yes, I've just received confirmation from the beta center, they
1169 are indeed the <b>THIRD</b> beta release of Mesa 3.1! Happy Days. Happy Days. Thanks
1170 Keith Whitwell for preparing these for us during Brian's absence.</p>

1173 <p>I'm pleased to announce that I've accepted a position with Precision Insight,
1174 Inc. effective October, 1999. I'll be leaving Avid Technology in September.</p>
1175 <p>I've been working on Mesa in my spare time for over five years. With Precision
1176 Insight I now have the opportunity to devote my full attention to advancing Mesa
1177 and OpenGL on Linux.</p>
1178 <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
1179 my work will continue to be open sourced and available to any other programmers who
1180 may want to contribute to it, or use it for other projects or platforms</p>
1181 <p>PS: I'm going to be traveling until Sep 6 and won't be reading email until then.</p>

1184 <p>Anonymous CVS access is back online so suck up all the bandwidth you can afford.
1185 Note that this is a new archive, so you will need to re-checkout the archive. That
1186 means don't <i>cvs update</i> from a previous download.</p>

1209 If you are into the quake scene, you may want to try this out, as it contains some
1210 optimizations specifically in the Q3A rendering path.

1217 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1218 US$10,000 to the Mesa project to support its continuing development.
1219 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1220 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1221
1222 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1223 improve performance on 3d hardware.  Thanks to Keith's work, many
1224 applications using Mesa 3.1 will see a dramatic performance increase
1225 over Mesa 3.0.  The donation will allow Keith to continue working on
1226 Mesa full time for some time to come.
1227

1229 information about id Software, Inc. see www.idsoftware.com.

1233 This donation from John/id is very generous.  Keith and I are very
1234 grateful.
