Abstract
The present invention relates to a system for interactively moving a hit point within a current triangle of the model, where the hit point defines a location of a brush stamp relative to the model, where a circle with a radius either defines the brush stamp or minimally contains the brush stamp. For each vertex of the current triangle containing the hit point, a sub-neighborhood of vertices of the model is defined by including in the sub-neighborhood vertices of the model that are within a distance of the hit point, the distance being a sum of the radius of the circle added to a length of a longest edge that is attached to the vertex. A sub-parameterization for each sub-neighborhood is then computed. The system then finds a barycentric coordinate of the hit point in the current triangle, where the barycentric coordinate has three barycentric values, each corresponding to a vertex of the current triangle. The system the computes a local parameterization by weighted averaging of the sub-parameterizations, where each sub-parameterization is weighted according to the barycentric value of the vertex of its sub-neighborhood.
