## Objectives

On completing the course, students should be able to

- use graphics hardware to render interactive images, both polygonal and implicit;
- understand the core technologies of ray tracing, rendering, and implicit surfaces;
- learn techniques of computational geometry and their applications to visualization;
- describe the underlying theory of splines and subdivision and define the Catmull-Clark and Doo-Sabin subdivision methods;
- understand several global illumination technologies such as radiosity and ambient occlusion;

## Recommended reading

Students should expect to refer to one or more of these books, but should not find it necessary to purchase any of them.
