1425 <h2>May 13, 1999</h2>
1426 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1427 US$10,000 to the Mesa project to support its continuing development.
1428 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1429 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1430
1431 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1432 improve performance on 3d hardware.  Thanks to Keith's work, many
1433 applications using Mesa 3.1 will see a dramatic performance increase
1434 over Mesa 3.0.  The donation will allow Keith to continue working on
1435 Mesa full time for some time to come.
1436

1438 information about id Software, Inc. see www.idsoftware.com.
