Projection matrices are necessary for a large portion of rendering computer graphics. There are primarily two different types of projection matrices – perspective and orthographic – which are used frequently, and are traditionally treated as mutually incompatible with each other in how they are defined. Here, we bridge the gap between the two different forms of projection matrices to present a single generalized projection matrix that can represent both.
