What do you understand by term ray casting? Explain briefly?
Expert
Ray casting is a technique in which the surfaces of objects observable to the camera are found by throwing or casting the rays of light from viewer to the scene. The main idea behind the ray casting is to shoot rays from the eye, one per pixel, and find out the closest object which block the path of that ray – imagine of an image as a screen door, with each and every square in the screen being a pixel.
