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