Hi all,

I would need to render an image and use the Tachyon-Optix (internal, GPU
accelerated) renderer. I would like to ask to quesitons:

1) How can I set manually the resolution of the output image with the
Tachyon-Optix internal renderer? Using "-res W H", which works for the
external Tachyon, gives an error.

2) How can I render the image using the internal Tachyon with VMD running
without the X server (to avoid bandwidth problems when working on a remote

Any help would be really appreciated. Thank you very much,
