Toric RayTrace - ray missing surface. If a ray cannot intersect with a surface [ignoring apertures], then a flag is set and the ray trace ceases. For toric raytraces, this ‘ray miss’ was properly detected, but the flag was not set, so the raytrace continued spuriously. The flag is now set appropriately.

Webb19 feb. 2015 · There are a few steps, though. If the camera ray intersects an object, then we need to calculate lighting (otherwise, just make the pixel black, as usual). At this point we want to calculate the intersection point, which is given by: intersectionPoint = cameraRay.origin + cameraRay.direction * intersectionDistance;
