I completed implentation of 6coloring for JSCAD, JSCAD_ and OpenSCAD today:
My planar graph playground tool "node.tetra.js" now creates planar graph sphere embeddings for JSCAD/OpenSCAD using the "same" spherical polygon and great circle arc (for graph edges) implementations:
When playing with both models, JSCAD preview mode is much faster than OpenSCAD preview for rotating the model, not sure whether it is a simpler preview or just better. Has anybody noticed similar?
Here is sample JSCAD model to play with online:
20KB JSCAD file:
Here is "same" sample OpenSCAD model (32KB) for download:
