<<TRUE PERSPECTIVE Good explaination of the way we actually see with curved perspective. Ive noted in my many years teaching color theory, composition and visual analysis that most people cannot see the curves. They know things like edges in architecture are straight, so they see what they know rather than really observing their visual field. In the same way the three point perspective that 3d programs use is disconcerting to viewers who percieve the limited two point perspective used in most architectual drawings as more realistic. Render blowup in 3ds and special cameras for architecture "solve" the problem of confronting viewers with a too real perspective of a scene. I think that curved perspective would be great for giving scenes the radical expressiveness of an Escher print but would not be considered real looking by most viewers. A work around is to map the animation onto a sphere, controlling the strength of the effect by changing the # of degrees of the sphere the map takes up. Ed
