John,

In fact, I do not have a NVidia graphics card, I have a Matrox
Millennium P750 card. So I would like to use a CAVE- or
FreeVR-enabled version of VMD. However, at the download
web site, it only shows

IRIX6 OpenGL (SGI IRIX 6.5 using hardware OpenGL + CAVE)

is CAVE-enabled. Are there a Linux version CAVE-enabled VMD
available now?

Thanks a lot,

Joe Zhou
