### Abstract

This paper describes a new algorithm to compute radiance in a synthetic
environment. Motivated by the success of wavelet methods for radiosity
computations we have applied multi wavelet bases to the computation of
radiance in the presence of glossy reflectors. We have implemented this
algorithm and report on some experiments performed with it. In particular
we show that the convergence properties of basis functions with 1--4
vanishing moments are in accordance with theoretical predictions. As in the
case of wavelet radiosity we find higher order bases to have advantages.
However, the cost scaling due to the higher dimensionality of the problem
is such that the higher order bases only become competitive for very high
precision requirements. In practice we rarely go beyond piecewise linear
functions.
