TQ3Ellipsoid Data Caps Field Explanation

Q: I am perplexed as to what the caps field in the TQ3EllipsoidData structure is used for. Can you explain?

A: Here's an explanation. If you cut a pool ball in half, you get a solid hemisphere. If you cut a basketball in half, you get a hollow hemisphere. The intention of the caps is to specify which sort of a ball you'd like to pretend you're rendering. You will IN THE FUTURE (NOT for 1.5.1) be able to specify min and max parameter values, making partial ellipsoids (cones, etc.). When this feature is released, you can either leave the caps field value as none (kQ3EndCapNone), in which case you'll get a hollow-looking partial sphere, or interior (kQ3EndCapMaskInterior), in which case you'll get a solid-looking partial sphere.
