== Manually ==

To get a stereo diagram you need to images. The left image is rotated +3 degrees and the right image is rotated -3 degrees.

To obtain the left image, type:
ray angle=+3
png left-image.png
Likewise, to obtasin the right image, type:
ray angle=-3
png right-image.png

You still use any other [[ray]] based modifications, such as:
ray 1600,1200,angle=+3
png big-left-image.png

== Script ==

A user on the PyMol list wrote a very nice little stereo ray tracing script. Just copy this to a text file. Then, in PyMol run
run dirName/scriptName.pym
where '''dirName''' is where you put it, and '''scriptName''' is what you named the file then run one something like the example lines given:
<source lang="python">
EXAMPLE
stereo_ray output, 1000, 600
stereo_ray secondImage.png
</source>
This will create to images, one with an L and one with an R suffix. Just paste the two images next to each other (in some image editing program) and you're done.

<source lang="python">
from pymol import cmd

def stereo_ray(output='', width='', height=''):
'''
DESCRIPTION
"stereo_ray" ray-traces the current scene twice (separated by
a six-degree rotation around the y axis)
and saves a pair of images that can be combined in any image
manipulation software to form a stereoimage.
The first argument, the output file name, is mandatory.
The second and third arguments, the size of the image, are not.
If the width is given, the height will be calculated.

USAGE
stereo_ray filename [, width [, height]]

EXAMPLE
stereo_ray output, 1000, 600
stereo_ray secondImage.png
'''

if output == '':
print 'no output filename defined\n'
print 'try: \'stereo_ray filename\''
return -1
# abort if no output file name given

if width == '':
width,height = cmd.get_session()['main'][0:2]
# get dimensions from viewer if not given

elif height == '':
oldWidth,oldHeight = cmd.get_session()['main'][0:2]
height = int(width)*oldHeight/oldWidth
# calculate height from proportions of viewer if
# only width is given

cmd.ray(width, height, angle=-3)
cmd.png(output+"_r")
cmd.ray(width, height, angle=3)
cmd.png(output+"_l")

cmd.extend('stereo_ray',stereo_ray)
</source>
