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