A more robust approach is described in which ray tracing is used to perform the numerical integration of the form-factor equation, tailored to provide good, approximate results for a low number of rays, while still providing a smooth continuum of increasing accuracy for higher numbers of rays.

A new method for computing form-factors within a progressive radiosity approach is presented. Previously, the progressive radiosity approach has depended on the use of the hemi-cube algorithm to determine form-factors. However, sampling problems inherent in the hemi-cube algorithm limit its usefulness for complex images.

Previously, the progressive radiosity approach has depended on the use of the hemi-cube algorithm to determine form-factors. However, sampling problems. It avoids form factors by using ray-tracing to do the same task. “A Ray Tracing Algorithm for Progressive Radiosity”. John R. Wallace, Kells A. Elmquist, Eric A.
Radiosity vs. Ray Tracing Radiosity

Ray tracer cannot simulate the interreflection of light between diffuse Surfaces. Slide 4 Lecture 20 6.837 Fall ‘01 Ray Tracing vs. Radiosity Ray tracing is an image-space algorithm, while radiosity is computed in object-space. Because the solution is limited by the view, ray tracing is often said to provide a view-dependent solution
