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. Yves Daoust 54209.

Do a similar … 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. WebDec 11, 2024 · Nobody described the algorithm here, but the Graphics Gems algorithm is simply: Using your ray's direction vector, determine which 3 of the 6 candidate planes would be hit first. If your (unnormalized) ray direction vector is (-1, 1, -1), then the 3 planes that are possible to be hit are +x, -y, and +z.
