Eitan,
	There's a comprehensive help system. Read it.

To answer your question, Bicubic patches are a a 3D surface made up of a
mesh of triangles. Good for creating things like folds in paper at the
spine of a book. I suggest you leave well alone if you are new to POVray
and use a modeller for these, I reccommend Moray, find it somewhere on
www.povray.org

Spatch is much better than Moray when making bicubic patches.

  If you look in the announcement group on this server you will find my
links collection. It contains links to just about every Pov related utility
and information site you can think of including a link to SPatch.
