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. WebThe Möller–Trumbore ray-triangle intersection algorithm, named after its inventors Tomas Möller and Ben Trumbore, is a fast method for calculating the intersection of a ray and a triangle in three dimensions without needing precomputation of the plane equation of the plane containing the triangle.

"WebThere will be either 0 or 1 intersection. The intersection only counts if it is within the cylinder's circle, of course. For capped cylinders, you will need to consider the intersection of a ray with not only the cylinder walls, but with the two caps. As always, the closest positive intersection is the one used.

WebIntersecting a disk • Intersecting circles is similar to intersecting quadrilaterals • The extent check, after computing the intersection point, becomes one of using the circle equation • Consider a circle lying on the z=0 plane. If the ray intersects the z=0 plane, it also intersects the circle if: x2 +y2 −1 ≤ 0

WebDo a similar computation to find the intersections with the planes of the two basis. You will get two pairs [tc0, tc1], [tp0, tp1]. If these intervals do not overlap, the ray doesn't hit the cylinder. Otherwise, the largest of tc0 and tp0 tells you what surface is actually hit, and this t value tells you where.
