<DIV><FONT face=Verdana><FONT size=2>I have built a polarized passive
stereo display system based on one computer equiped with two projectors. It
works well in side-by-side mode stereo. Recently I installed paraview as
one application on it with some modificaiton made paraview to
support side-by-side stereo. The modification is very simple : just
split the viewport into two parts and show the left-eye image and
right-eye image side-by-side. Although it works,
its stereo effect is not good, especial
when scaling objects. I wish an effect like flying over
the objects, so is it necessary to set the stereo parameters on
flying?</FONT></FONT></DIV>
