Abstract

We describe how the radiosity method can be used to compute the global illumination of a static scene with dynamic lights. A transfer function that maps the direct illumination to the global illumination is precalculated. Real-time performance is reached for simple scenes.

Nyckelord

Global illumination; radiosity; real-time; precomputed radiance transfer
