In this work-in-progress paper, we present a solution to the illumination problem that is intermediate between the conventional local and global approaches to illumination. It involves the representation of radiance on a surface as a finite element expansion in terms of wavelets.
By expanding in terms of ``Nusselt coordinates'', we show how irradiance, transport, and surface interaction can be evaluated simply and directly in terms of wavelet coefficients. We present an example of transport.
