Description
LineTrace approximates ray-torus intersection by intersecting the ray with the plane in which the torus lies, then determining a hit point closest to the linear circle defined by torus center and torus outer radius. If the torus lies at a glancing angle, the ray-torus intersection is performed against cylinders approximating the shape of the torus.
