This document provides an overview of the graphics pipeline in 3D computer graphics. It involves transforming coordinates from the model space through the eye space, normalized device coordinates, and projected coordinates before outputting to a window. A series of transforms are involved including modelview, projection, and viewport transforms to prepare the 3D graphics for output on a 2D display.
