Abstract

We present a novel method which supports the tuning of a variety of stationary subdivision schemes to give the best possible behaviour near extraordinary vertices. The new tuning method uses a novel set of freedoms and is based on the use of the mask rather then the stencils.
In using the mask rather then the stencils we resolve the problem occurring when extraordinary points fall close together. It also gives an obvious count to the number of freedoms available for tuning. We tune the coefficients in the mask, and then re-normalise the linear combinations giving the new vertices by summing the contributions and dividing the total by the sum of the coefficients used.
