Aims

This course provides students with a solid grounding in the main three-dimensional modelling and rendering mechanisms. It also introduces supporting topics, including graphics cards, mobile graphics, and animation.

Lectures

The order of delivery of lectures is provisional and subject to change.

  • Computational geometry. The mathematics of discrete geometry: what can you know, and how well can you know it?

  • Ray tracing. The fundamentals of raycasting, constructive solid geometry (CSG), and bounding volumes.

  • Implicit surfaces, voronoi diagrams. Useful graphical and geometric techniques.

  • Splines and subdivision surfaces. Bézier curves and B-splines, from uniform, non-rational B-splines through to non-uniform, rational B-splines (NURBS). Introduction to subdivision. The key methods. Pros and cons when compared with NURBS.

  • Advanced illumination techniques. Radiosity and photon mapping.

  • OpenGL, graphics cards, and shaders. Tools and technologies available today; previews of what’s coming tomorrow.

Objectives

On completing the course, students should be able to:

  • compare and contrast ray tracing with polygon scan conversion;

  • define NURBS basis functions, and explain how NURBS curves and surfaces are used in 2D and 3D modelling;

  • describe the underlying theory of subdivision and define the Catmull-Clark and Doo-Sabin subdivision methods;

  • understand the core technologies of ray tracing, constructive solid geometry, computational geometry, implicit surfaces, and particle systems;

  • understand several global illumination technologies such as radiosity and photon mapping, and be able to discuss each in detail;

  • be able to describe current graphics technology and discuss future possibilities.
