My father facets gemstones. Several years ago there were several ray
tracing packages that would allow a user to model their cut by specifying
the facet angles and degrees. You would specify the gemstone material,
and the ray tracer would then render your cut and you would be able to see
what it was going to look like. Does anyone here know where I could get
such a package? Or, does anyone here know someone who would know?
Thank you for your help.
