Ray
DESCRIPTION
"ray" creates a ray-traced image of the current frame. This can take some time (up to several minutes, depending on image complexity).
USAGE
ray [width,height [,renderer [,angle [,shift ]]]
angle and shift can be used to generate matched stereo pairs
EXAMPLES
ray ray 1024,768 ray renderer=0
PYMOL API
cmd.ray(int width,int height,int renderer=-1,float shift=0)
NOTES
To magnify the effect of perspective on the scene,
set field_of_view, X
where 50<X<70. Default is 20. 50-70 gives a very strong perspective effect. Nb. the field of view is in Y, not X as one would expect.
renderer = -1 is default (use value in ray_default_renderer) renderer = 0 uses PyMOL's internal renderer renderer = 1 uses PovRay's renderer. This is Unix-only and you must have "x-povray" in your path. It utilizes two temporary files: "tmp_pymol.pov" and "tmp_pymol.png".

USER Comments
How do I ray trace a publication-ready (~300dpi) image using PyMol?
