Is there a shape that can build a tapered square profile that renders correctly in OpenGL?
As far as I can tell, all the shapes with 0, 1 status (PYRAMID, SWEEP, TUBE, etc) render like it is assumed the shape is rounded. Same for MASS and HPRISM_.
The attached image is a SWEEP on top of a PRISM_. The tapered portion should have square corners like the base, not be ‘smoothed’ or whatever.
