Gem cuts

I've been developing an approach to modelling gem cutting designs using OpenSCAD. So far I've created a simple brilliant cu, a pinwheel cut and a triangular faceted sphere from the US Faceters Guild and ccsq03 from the UK Faceters Guild.

Others will be added as I continue this modeling work.

Requires the latest version of OpenSCAD (uses concat). Care is needed to ensure that the design is able to be rendered due to issues with CGAL.The approach and links to code are in my blog:
