solidSweep
A profile (x, y pairs in the plane across the path) swept along a polyline path (x, y, z
triples). At each point the frame is right = up × tangent, up' = tangent × right, so profile x
runs right and profile y runs up; up defaults to +Y. Sides are faceted; capEnds closes both
ends. Texture u runs around the profile and v along the path, both 0..1.

Corners are not mitred: a sharp turn pinches the section. A path that turns sharply wants more points.
