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. WebA ray is used to determine what light would be going towards the camera at that point and direction. In our case each ray represents a pixel in the output image and the resulting color of the ray determines the color output for … can cats be mentally ill
