  1055. <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of

  1056. US$10,000 to the Mesa project to support its continuing development.

  1057. Mesa is a free implementation of the OpenGL 3D graphics library and id's

  1058. newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.

  1059. 

  1060. The donation will go to Keith Whitwell, who has been optimizing Mesa to

  1061. improve performance on 3d hardware.  Thanks to Keith's work, many

  1062. applications using Mesa 3.1 will see a dramatic performance increase

  1063. over Mesa 3.0.  The donation will allow Keith to continue working on

  1064. Mesa full time for some time to come.

  1065. 

  1066. For more information about Mesa see www.mesa3d.org.  For more

  1067. information about id Software, Inc. see www.idsoftware.com.
