Using Semi-Regular 4–8 Meshes for Subdivision Surfaces

Luiz Velho

Open publisher page 26 citations

Abstract

Semi-regular 4–8 meshes are refinable triangulated quadmngulations. They provide a powerful hierarchical structure for multiresolution applications. In this paper, we show how to decompose the Doa-Sabin and Catmull-Clark subdivision schemes using 4–8 refinement. The described technique makes it possible to use these classical subdivision surfaces with semi-regular 4–8 meshes.
