Mesh   Index


Two parametric-associative rules, one for quadrilaterals the other for triangles, generate an apparently quasi-random pattern across a mainly quadrilateral mesh. Three more rules, including one non-parametric rule, translate the pattern into a surface with outlines of holes for laser-cutting. The non-parametric rules serves to replace the perpendicular ends of a rectangular cut line into semi-circles.

The final result:

The rules and derivation:
