Abstract
Official abstract text for this publication.
An analytical method to efficiently convert a function that is stored in spherical harmonics into a function that is stored in a wavelet or mip map representation enables a variety of computer graphics functions to be efficiently performed. A function may be stored as a spherical harmonic representation and rotated in the spherical harmonic domain; the function can then be converted to a wavelet representation. The conversion method may be used to convert a spherical harmonic function to wavelets, and then an importance sampling technique may be applied to the wavelet representation to generate a set of importance samples for the function. The conversion method may be applied to convert a spherical harmonic representation into the wavelet domain, and an importance sampling technique may then be applied which samples the product of the function and another function in the wavelet domain.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer-implemented method, comprising: storing a function as a spherical harmonic representation that is a weighted sum of basis functions; converting, by a computing device, the spherical harmonic representation of the function into a multi-resolution representation of the function according to an analytic conversion technique, the analytic conversion technique including: calculating an integral of the spherical harmonic representation of the functio…
