New description:
The bug is described below. To fix this and close this ticket, just
slightly refactor the code in sage/sage/plot/plot3d/base.pyx so that save
to png on a 3d image saves the tachyon rendered file, gives an sobj on an
sobj or no extension, and gives an error on all other extension. This
will be all one gets initially.
Another *later* ticket should -- if possible -- make it possible to get
the static image from jmol (if possible).

This is a bug. There's currently no easy nice way to script
saving 3d graphics using Tachyon. If you do the following
sage: p = point3d([(k,k^2,0) for k in [0..10]], size=5,
viewer='tachyon')
sage: p.show(filename='a', viewer='tachyon')
then the file a.png will be produced but unfortunately a browser window
will also appear showing this file.
