In this work we introduce a new method for computing Form Factors in Radiosity. We demonstrate how our method improves on existing projective techniques such as the hemicube. We use the Nusselt analog to directly compute form factors by projecting the scene onto the unit circle. We compare our method with other form factor computation methods. The results show an improvement in the quality/speed ratio using our technique.
