Particularly on systems with non-mesa OpenGL implementations, I've
found it to be a pain to install mangled mesa and get VTK to use it.

I'd recommend Glen Lehmann's vtkXOpenGLOffScreenRenderWindow:

http://www.imaging.robarts.ca/~glehmann/OffScreen/OffScreen.html

We've been using it for some time with VTK4.2 / VTK4.4 with no issues,
and it was much easier than rebuilding VTK with mesa.


Of course, I'm assuming here that your server is UNIX-based...
