78Gallium3D is the codename for the new Mesa device driver architecture
79which is currently under development.
80A <a href="http://www.tungstengraphics.com/wiki/index.php/Gallium3D"
81target="_parent"> summary</a> of the architecture can be found on the

84<p>
85Gallium3D development is taking place on the <em>gallium-0.1</em> branch
86of the git repository.
87Currently, there's only a software-only driver and an Intel i915/945 driver
88but other drivers will be coming...

1167The donation will go to Keith Whitwell, who has been optimizing Mesa to
1168improve performance on 3d hardware. Thanks to Keith's work, many
1169applications using Mesa 3.1 will see a dramatic performance increase
1170over Mesa 3.0. The donation will allow Keith to continue working on
1171Mesa full time for some time to come.
