Abstract :
This paper presents a parallel algorithm for radiosity computation in virtual reality environment by computing the parallel eigenvalues and eigenvectors of form factor matrix. This leads to a novel approach to radiosity computation for virtual reality which called parallel eigenvector radiosity. Through the performance evaluation, this method significantly decreases the execution time for complex environments on cluster of PCs.
