Advanced 3D Graphics for Movies and Games

Brief Description

Advanced course in computer graphics with the emphasis on image synthesis. The course covers methods for physically-based realistic rendering used for special effects in movie production, computer animation, architectural and product visualizations etc. Specifically, we start off by briefly covering some of the math and physics behind light transport. We then give a detailed treatment of the industry-standard Monte Carlo methods for light transport simulation, such as path tracing, photon mapping etc. We also cover some of the more advanced techniques such as bidirectional path tracing.

Note: This class loosely follows up on Photorealistic Graphics (NPGR004) and is aimed mostly at students with a deeper interest in realistic rendering methods.
