Every frame of a game, film or CAD model is a small miracle of arithmetic: millions of coloured pixels computed from a scene made of numbers, sixty times a second. Computer graphics is the mathematics and engineering of turning a 3-D world into a 2-D image — and it is one of the most beautiful applications of linear algebra there is.

This branch follows the rendering pipeline: raster versus vector, 2-D and 3-D transforms built from matrices, projection and the camera, rasterization, ray tracing, and shading, lighting, colour and texture. Every transform here is a matrix multiply.
