- There are other three-sided objects than coins (right-angle cylinders).
-
- Consider the following object. It's a cylindrical section, but best
- described by its three orthographic projections: triangle, circle, and
- parabola. Another description would be a right-angle cylinder viewed
- from the side (rectangle view) and bisected by the plane perpendicular
- to the viewer and passing through one apparent corner of the cylinder to
- its opposite; one half of the result is the object.
-
- This flipping object can rest on one of two flat faces, or on its curved
- side. So does anyone want to figure the angle versus radius to get a 1/3
- randomizer?
