1. A method for optimizing signal stretch of a parametrization scheme in connection with computer graphics, comprising: parametrizing a mesh utilizing a signal stretch metric, wherein the signal stretch metric is used to measure a plurality of signal stretch metric values corresponding to how much undersampling exists for different points on the surface of the mesh in accordance with both spatial relationships of the mesh and the signal on the surface of the mesh; and minimizing the plurality of signal stretch metric values to minimize undersampling over all points for the surface of the mesh.
