 126 Gallium3D is the codename for the new Mesa device driver architecture
 127 which is currently under development.
 128 A <a href="http://wiki.freedesktop.org/wiki/Software/gallium"
 129 target="_parent"> summary</a> of the architecture can be found on the
 130 Tungsten Graphics website.
 131 </p>
 132 <p>
 133 Gallium3D development is taking place on the <em>gallium-0.1</em> branch
 134 of the git repository.
 135 Currently, there's only a software-only driver and an Intel i915/945 driver
 136 but other drivers will be coming...

1157 <p>
1158 </p><h2>September 21, 1999</h2>
1159 <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>
1160 and <a href="ftp://ftp.mesa3d.org/mesa/beta/MesaDemos-3.1beta3.tar.gz">MesaDemos-3.1beta3.tar.gz</a>,
1161 that seem to be... yes, I've just received confirmation from the beta center, they
1162 are indeed the <b>THIRD</b> beta release of Mesa 3.1! Happy Days. Happy Days. Thanks
1163 Keith Whitwell for preparing these for us during Brian's absence.</p>

1166 <p>I'm pleased to announce that I've accepted a position with Precision Insight,
1167 Inc. effective October, 1999. I'll be leaving Avid Technology in September.</p>
1168 <p>I've been working on Mesa in my spare time for over five years. With Precision
1169 Insight I now have the opportunity to devote my full attention to advancing Mesa
1170 and OpenGL on Linux.</p>
1171 <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
1172 my work will continue to be open sourced and available to any other programmers who
1173 may want to contribute to it, or use it for other projects or platforms</p>
1174 <p>PS: I'm going to be traveling until Sep 6 and won't be reading email until then.</p>

1177 <p>Anonymous CVS access is back online so suck up all the bandwidth you can afford.
1178 Note that this is a new archive, so you will need to re-checkout the archive. That
1179 means don't <i>cvs update</i> from a previous download.</p>

1202 If you are into the quake scene, you may want to try this out, as it contains some
1203 optimizations specifically in the Q3A rendering path.

1210 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1211 US$10,000 to the Mesa project to support its continuing development.
1212 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1213 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1214
1215 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1216 improve performance on 3d hardware.  Thanks to Keith's work, many
1217 applications using Mesa 3.1 will see a dramatic performance increase
1218 over Mesa 3.0.  The donation will allow Keith to continue working on
1219 Mesa full time for some time to come.
1220

1222 information about id Software, Inc. see www.idsoftware.com.

1226 This donation from John/id is very generous.  Keith and I are very
1227 grateful.
