Abstract

We propose an adaptive interpolatory scheme for subdivided triangle meshes that is compliant with the modified butterfly subdivision and can be used effectivelv and efficientlv in selective editing of meshes. Our scheme is developed upon the RGB subdivision, an adaptive scheme that is based on the factorization of the one-to-four triangle split pattern. We introduce the concept of topological angle and related operators to efficientlv navigate and edit an adaptivelv subdivided mesh. On the basis of this new scheme, we present an interactive application that allows a user to freelv edit the Level of Detail of a modei starting at a base mesh.
