Hi,
If indirect rendering is not possible, another option is to use
VirtualGL. With VirtualGL, you can use the server's GPU for rendering
and have the rendered results sent to your local or virtual X server.
Depending on the graphics setup, the network speed, and the data size,
this approach may also give you noticably better performance than
indirect rendering.
Cheers,
Kristian
