  85 Gallium3D is the codename for the new Mesa device driver architecture
  86 which is currently under development.
  87 A <a href="http://www.tungstengraphics.com/wiki/index.php/Gallium3D"
  88 target="_parent"> summary</a> of the architecture can be found on the
  89 Tungsten Graphics website.
  90 </p>
  91 <p>
  92 Gallium3D development is taking place on the <em>gallium-0.1</em> branch
  93 of the git repository.
  94 Currently, there's only a software-only driver and an Intel i915/945 driver
  95 but other drivers will be coming...

1117 </p><h2>September 21, 1999</h2>
1118 <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>
1119 and <a href="ftp://ftp.mesa3d.org/mesa/beta/MesaDemos-3.1beta3.tar.gz">MesaDemos-3.1beta3.tar.gz</a>,
1120 that seem to be... yes, I've just received confirmation from the beta center, they
1121 are indeed the <b>THIRD</b> beta release of Mesa 3.1! Happy Days. Happy Days. Thanks
1122 Keith Whitwell for preparing these for us during Brian's absence.</p>

1125 <p>I'm pleased to announce that I've accepted a position with Precision Insight,
1126 Inc. effective October, 1999. I'll be leaving Avid Technology in September.</p>
1127 <p>I've been working on Mesa in my spare time for over five years. With Precision
1128 Insight I now have the opportunity to devote my full attention to advancing Mesa
1129 and OpenGL on Linux.</p>
1130 <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
1131 my work will continue to be open sourced and available to any other programmers who
1132 may want to contribute to it, or use it for other projects or platforms</p>
1133 <p>PS: I'm going to be traveling until Sep 6 and won't be reading email until then.</p>

1136 <p>Anonymous CVS access is back online so suck up all the bandwidth you can afford.
1137 Note that this is a new archive, so you will need to re-checkout the archive. That
1138 means don't <i>cvs update</i> from a previous download.</p>
1139 <p>
1140 </p><h2>August 17, 1999</h2>
1141 <p>A report from the SIGGRAPH '99 Linux/OpenGL
1142 BOF meeting is now available.</p>

1161 If you are into the quake scene, you may want to try this out, as it contains some
1162 optimizations specifically in the Q3A rendering path.

1164 </p><h2>May 13, 1999</h2>
1165 <p>For those interested in the integration of Mesa into XFree86 4.0, Precision Insight

1169 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1170 US$10,000 to the Mesa project to support its continuing development.
1171 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1172 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1173
1174 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1175 improve performance on 3d hardware.  Thanks to Keith's work, many
1176 applications using Mesa 3.1 will see a dramatic performance increase
1177 over Mesa 3.0.  The donation will allow Keith to continue working on
1178 Mesa full time for some time to come.
1179

1181 information about id Software, Inc. see www.idsoftware.com.

1185 This donation from John/id is very generous.  Keith and I are very
1186 grateful.
