WebMar 28, 2024 · This class provides an Object which is a Cyclinder centred at the origin, with radius 1. The clyinder is aligned with the -axis, and extends to along that axis, as illustrated below. Note that the Cylinder provided in the skeleton code is not complete, and returns no RayIntersection s from intersect (). This method needs to be implemented ... 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.
