Could someone please provide a clear and concise description without
getting over technical of the difference between polygons &
ray-tracing?  My location provides limited access to current info.....
it just cost me $11.00 to get a copy of an article of "Presence." If
you do wish to be technical that's cool too, I figure some reply is
better than no reply. I'm a cognitive psychologist and VR has recently
become a fascination for me. My C.S. background is limited but is
increasing.  Also, any prospective dangers (like epilepsy), social,
economic, moral, and ethical concerns that maybe should be
considered.....I'm interested in ideas. Thanks to one and all.
