Variance Shadow Maps. Convolution Shadow Maps. Exponential Shadow Maps. Layered Variance Shadow Maps. What Direction Does Light Travel?. Light travels in straight lines.. How Are Shadows Made?. Shadows are made when there is an object blocking the light from hitting the surface.. The object needs to be a solid object. If it is clear then the sun will pass through it, whereas a solid object will block it..
