10,
000 to the Mesa project to support its continuing development.
1346 Mesa is a free implementation of the OpenGL
3D graphics library and id's
1347 newest game, Quake
3 Arena, will use Mesa as the
3D renderer on Linux.
1349 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1350 improve performance on
3d hardware. Thanks to Keith's work, many
1351 applications using Mesa
3.1 will see a dramatic performance increase
1352 over Mesa
3.0. The donation will allow Keith to continue working on
1353 Mesa full time for some time to come.
