VMD-L Mailing List

Jun,
  Jacob is referring to the "snapshot" rendering mode that is built into
VMD. VMD can eiether capture images from its own OpenGL window and use those
to make the movies ("snapshot" mode), or you can use high quality ray tracing
packages like Tachyon, POV-Ray, and others to make the movies, by selecting
the rendering mode in the graphical interface for the VMD Movie plugin.

Cheers,
  John Stone
