....global illumination. The situation is quite different for the Galerkin method, however, where the ij th matrix element is given by (71) This expression is still complex, but managable in the diffuse case. Zatz took this approach, choosing polynomial basis functions defined over individual patches [39]. The resulting expressions for (Kui[ uj require quadruple integrals, yet their support is limited to the pair of patches involved, making the computation of the inner products feasible. Heckbert attacked the diffuse case using the finite element method, which is a special case of the Galerkin ....
