Abstract
A method of rendering a graphical scene includes determining a plurality of functions that contribute to a light transport model of the scene, projecting each function of the plurality of functions into the wavelet domain, encoding basis coefficients of each function in a wavelet tree, each function being encoded in at least one wavelet tree such that the plurality of functions are represented in the wavelet domain by a plurality of wavelet trees, traversing direct paths through the plurality of wavelet trees, along which direct paths an integral coefficient may be nonzero, to determine the radiance of a point in the scene, and rendering the scene.
