I wish to render a picture with a focal blur effect using POVRay. The
focal point corresponds to the geometric center of an atom selection.
How can I convert its PDB coordinates into POVRay coordinates?
Actually, there is a second layer of complexity to my problem. I also
wish to display periodic images of my system, which will put the focus
point on the front periodic image, i.e. center + box length in PDB
