mesh algorithms

Cylinder, cone, frustum and pipe

Generate straight solids of revolution: cylinders, cones, truncated cones and bored pipes, with flat-shaded caps and UVs. Use it for columns, cups, nozzles, pipes and lamp shades.

Limits to consider

Only straight sides (no curved profile; see a lathe for that) and a constant-radius bore. Caps and walls own separate vertices for sharp shading, so closed results are watertight after welding. A cone apex holds one vertex per segment.
