18. Pre-Computed Radiance Transfer: Theory and Practice
Half-Day, Monday, 1 August, 8:30 am - 12:15 pm
Petree Hall C
Level: Intermediate
Realistic shading and how it can be achieved using precomputed radiance transfer. The course covers: the theory underlying a general model of shading and shadowing for real-time rendering, basic radiance transfer techniques, more advanced techniques that incorporate higher-frequency lighting and arbitrary BRDFs, the differences among these algorithms, and insights the presenters have gained working in this area. And it includes implementation details and a complete theoretical derivation.
Prerequisites
Some knowledge of a low-level graphics API such as DirectX or OpenGL. Knowledge of shading algorithms, linear algebra, and basic global illumination is useful.
Intended Audience
Everybody who is interested in realistic real-time shading. The course is designed for people who already have some knowledge of real-time rendering and want to learn a more sophisticated shading technique.
