 I've got hold of a version of rayshade 3.0 which has been adapted to
do bi-cubic patches. It came with a definition file for the teapot. It
works a treat, but I'd really like to know where I can get the source
code for the procedures necessary, ie makebcpatch,intbcpatch,nrmbcpatch
and bcpatchextent. If anybody has any other additions such as for
bezier/beta splines, or anything else I would much appreciate some
pointers. I have the rayshade 4.0 beta release, but bcpatches would be
nice

Ciao
