Real-time shadows are a must if you want to pull off realistic real-time rendered scenes. This tutorial shows how to do planar shadows, which is the rendering of the shadow of an object onto a flat “plane like” surface. To accomplish this, the tutorial uses a two render pass shader, the stencil buffer, and what is known as the “shadow matrix”.
