[Chimera-users] Wall eye stereo has no depth in orthographic projection

Stereo views derive from binocular vision where the left and right eyes 
see slightly different orientations of the same scene.  Perspective 
projects approximates the positions of the two eyes and generate two 
images that differ by a shearing transformation, and you get the stereo 
effect.  Orthographic projection effectively places the eye infinitely 
far away in the viewing direction, so the views for left and right are 
identical, and you do not get the stereo effect.  Thus, stereo viewing 
and orthographic projection are inherently incompatible and should not 
be used together.
