MASSIVELY-PARALLEL HEMISPHERICAL PROJECTION FOR PROGRESSIVE RADIOSITY

This paper describes a massively parallel implementation of the progre ssive radiosity algorithm. Our algorithm is based on an hemispherical projection approach, which provides an accurate form factor approximat ion. As the projection plane is mapped onto a processor mesh, we propo se different techniques that decrease computation time by reducing pro cessor inactivity as much as possible. This approach successfully hand les large sets of form factor sampling elements.
