Abstract : We present the result of experimentations and tests with Wavelet Radiosity. We have developed a powerful wavelet radiosity implementation where we can independantly modify every geometrical component of the scene (description of the input data, representation of spectral distribution, etc.) and every component of the global illumination algorithm (visibility algorithm, wavelet basis, etc.). This implementation has been tested on real world applications: an archaeological site reconstruction with daylight illumination, an opera house front with artificial illumination and the Soda Hall building inside illumination. In this paper, wepresent the results of our experiments, which are mostly about the interdependencies of the different parts of the general algorithm and the influence of each one on the final result. We also introduce several improvements to the wavelet radiosity algorithm that allow for higher rendering speed and lower memory use, thereby allowing rendering of architectural models of high complexity.
