| 摘 要： | The incremental radiosity method has been shown to be an efficient technique for providing global illumination in dynamic environments as it exploits temporal coherence in object space.This paper presents an accelerated incremental radiosity algorithm,which is based on a dynamically followed partial matrix.This not only reduces the computation cost in determining incremental form-factors when the geometrical relationships between objects are constantly changing,but also simplifies the management of user interaction with comparatively little storage cost.
