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 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 …

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. Of the 3 candidate planes, do find the t ...
