A method for synthesizing a given texture sample directly on the surface of a three-dimensional object is presented. The method combines the Heeger-Bergen texture synthesis algorithm with an implementation of the Laplacian pyramid transform on the sphere. It avoids the problems of distortion and discontinuity inherent in texture mapping by synthesizing texture directly on the object surface. Furthermore, because it is automatic, no artistic skill is required and no ad hoc parameter-tweaking is necessary. Finally, while it takes several iterations to terminate, it is notably inexpensive to compute. (1976K compressed postscript).
