Abstract
A restriction of the radiosity method has been the difficulty of processing environments consisting of curved surfaces. In order to apply current radiosity methods, such surfaces are usually subdivided into many polygonal patches. However, as the computational complexity of the radiosity method depends on the number of patches, this approach results in a very inefficient use of the available processing time and data storage capacity. In this paper, a ray tracing based radiosity method for diffuse and specular reflective Bézier surfaces is presented. The original Bézier surface description is used throughout the entire algorithm which makes the subdivision of each Bézier patch into many polygonal patches unnecessary.
