The document describes the 3D rendering pipeline which involves a sequence of transformations to draw 3D primitives into a 2D image. The key steps are:
1) Model transformation to transform objects into the 3D world coordinate system.
2) Viewing transformation to transform objects into the 3D viewing coordinate system based on camera position and orientation.
3) Projection transformation to project the 3D viewing coordinates onto a 2D plane.
4) Viewport transformation to map the 2D projected coordinates to the 2D viewport.
