Subdivision surfaces solve numerous problems related to the
geometry of character and animation models. However, unlike on parametrised
surfaces there is no natural choice of texture coordinates on subdivision
surfaces. Existing algorithms for generating texture coordinates on
non-parametrised surfaces often find solutions that are locally acceptable but
globally are unsuitable for use by artists wishing to paint textures. In
addition, for topological reasons there is not necessarily any choice of
assignment of texture coordinates to control points that can satisfactorily be
interpolated over the entire surface. We introduce a technique, pelting, for
finding both optimal and intuitive texture mapping over almost all of an entire
subdivision surface and then show how to combine multiple texture mappings
together to produce a seamless result.
