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

 164 <p>
 165 Gallium3D development is taking place on the <em>gallium-0.1</em> branch
 166 of the git repository.
 167 Currently, there's only a software-only driver and an Intel i915/945 driver

1191 <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>
1192 and <a href="ftp://ftp.mesa3d.org/mesa/beta/MesaDemos-3.1beta3.tar.gz">MesaDemos-3.1beta3.tar.gz</a>,
1193 that seem to be... yes, I've just received confirmation from the beta center, they
1194 are indeed the <b>THIRD</b> beta release of Mesa 3.1! Happy Days. Happy Days. Thanks
1195 Keith Whitwell for preparing these for us during Brian's absence.</p>

1198 <p>I'm pleased to announce that I've accepted a position with Precision Insight,
1199 Inc. effective October, 1999. I'll be leaving Avid Technology in September.</p>
1200 <p>I've been working on Mesa in my spare time for over five years. With Precision
1201 Insight I now have the opportunity to devote my full attention to advancing Mesa
1202 and OpenGL on Linux.</p>
1203 <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
1204 my work will continue to be open sourced and available to any other programmers who
1205 may want to contribute to it, or use it for other projects or platforms</p>
1206 <p>PS: I'm going to be traveling until Sep 6 and won't be reading email until then.</p>
1207 <p>
1208 </p><h2>August 23, 1999</h2>
1209 <p>Anonymous CVS access is back online so suck up all the bandwidth you can afford.
1210 Note that this is a new archive, so you will need to re-checkout the archive. That
1211 means don't <i>cvs update</i> from a previous download.</p>
1212 <p>

1234 If you are into the quake scene, you may want to try this out, as it contains some
1235 optimizations specifically in the Q3A rendering path.

1237 </p><h2>May 13, 1999</h2>

1242 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1243 US$10,000 to the Mesa project to support its continuing development.
1244 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1245 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1246
1247 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1248 improve performance on 3d hardware.  Thanks to Keith's work, many
1249 applications using Mesa 3.1 will see a dramatic performance increase
1250 over Mesa 3.0.  The donation will allow Keith to continue working on
1251 Mesa full time for some time to come.
1252

1254 information about id Software, Inc. see www.idsoftware.com.

1258 This donation from John/id is very generous.  Keith and I are very
1259 grateful.
