I really would like to hear from you.

Introduction
Plot3D has changed quite a bit from the initial version that used my own 3d routines. This version now produces publication quality (or almost publication quality) plots using some of the more advanced features of renderman. Check out the "History" entry for a detailed list of new features. There is also an archive of sample pictures and animations produced with plot3d(available in a separate file). This includes instructions for  producing the effects demonstrated in the examples. It's worth the effort to download it and check it out.

Full source is also available in a separate archive. Source may be modified for your own purposes, but you may not redistribute the result. If you make a useful change to the source, send it to me and I'll include it in the next release version (with full credit of course).

Enjoy!
