A field interpolated texture mapping algorithm for skeletal implicit surfaces

We address the problem of texture mapping implicit surfaces. Recent work in providing 2D mappings for implicit surfaces maps points from an auxiliary parametric (support) surface to the implicit surface. In this work we extend this method by observing that all commonly used skeletal elements are easily parameterized and can be used as their own support surfaces. In areas of a surface defined by the combination of multiple skeletal primitives we compute a mapping through relations found with the zero level surface of a primitive by using the gradient field.
