Given a two-dimensional polygon, this generates a three-dimensional extrusion of the shape by triangulating the polygon and creating a cylinder with that shape as the end faces.

The extrusion is always constructed with the polygon in the xy plane at
z = 0
and another copy at z = thickness
. Use
the transformation functions (e.g. rotate3d
) to
obtain other orientations and placements.
A mesh object containing a triangulation of the polygon for each face, and quadrilaterals for the sides.

for a simple polygon, triangulate
for
the triangulation, turn3d
for a solid of rotation.
