I was experimenting with Tachyon's depth of field camera option to
highlight some parts of a scene generated with VMD. It is however not
quite clear to me how I can determine where the focus of the rendering
will be. Is it at the origin (0,0,0)? Is there any easy way to
determine which settings are needed to focus on a given atom/residue/
fragement of a molecule?

Thanks in advance,

NB: Here is the changes that I made to the Tachyon file generated by VMD:

  projection perspective_dof
  focallength 0.75
  aperture 0.02
  Zoom 0.666667
