Texture Mapping with a Jacobian-Based Spatially-Variant Filter

In this paper, we describe a new method to map a texture on a surface with a spatially-variant filter. Our filter takes into consideration the effects of anisotropy using a Jacobian approximation while computing the sampling rate, and the interpolation weights are computed with a sinc function. We also discuss how to do forward and backward mapping with the filter, and extend our algorithms to 3D meshes. Our experimental results verify our analysis.
