1414 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1415 US$10,000 to the Mesa project to support its continuing development.
1416 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1417 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1418
1419 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1420 improve performance on 3d hardware.  Thanks to Keith's work, many
1421 applications using Mesa 3.1 will see a dramatic performance increase
1422 over Mesa 3.0.  The donation will allow Keith to continue working on
1423 Mesa full time for some time to come.
1424

1426 information about id Software, Inc. see www.idsoftware.com.
