*****  That might be true for freeviewing on a computer screen, but it's not
necessarily true when it comes to viewing with LCS glasses, or full screen
anaglyphic for that matter. Then you're back into a similar geometry to the
hand held viewer or a small version of projection. I find that I don't mind
the lack of Ortho in freeviewing, since interpretation of the image is still
possible, and I observe proportional relationships much the same way that I
would enjoy a flat photograph, except that with 3D a very realistic sense of
depth is part of the proportions to be enjoyed.

For me Ortho is more of a universal reference point, not necessarily the
ultimate imaging goal.
