Is it possible to render a stereo view in pymol?

Easily. Load the attached script and use it.

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)
