Abstract
This paper discusses different interpolation schemes for the radiosity method. It is shown that similar mathematical expressions exist for piece-wise constant approximation and linear approximation of the radiosity function. The latter improves accuracy and does not necessarily entail a higher complexity. Our implementation of a linear interpolation scheme demonstrates that hierarchical and adaptive meshing can be used elegantly.
