WebFeb 7, 2014 · They call these ray packets in raytracing literature. I'd suggest using 6 rays for the cylinder's radius, and one for the centre, totalling 7. You could even get away with as few as 4 or 5 rays, depending on how you want approximate the cylinder shape. This will be fast for non-axis-aligned objects, and can be blisteringly fast for AABBs.
