Abstract

This paper researches on the real time subdivision of surface rendering using approximation scheme and focuses on two methods - Catmull-Clark and Loop subdivision. The two methods are commonly employed separately in many existing applications and graphics engine. Catmull-Clark outperforms on quad meshes and Loop subdivision superiors on triangle meshes. The exchange of the meshes produces ugly polygonal meshes. In this paper, we propose to combine the methods and subdivide the quad-triangle model simultaneously. We average the vertex points generated by both the functions. This closes up the gap on the original vertex points. Our result turns out to be smoother and without defect. Our proposed method is potential to be employed in other graphics applications such as morphing, animation and etc.
