Abstract
CAGD is the abbreviation for Computer Aided Geometric Design. In CAGD, the subdivision scheme is gaining popularity among the computer graphics and geometric modeling community and has achieved considerable success. The objectives of this dissertation are to study and to understand the subdivision schemes of Chaikin's algorithm and Catmull & Clark's algorithm. Then, these subdivision schemes is applied to obtain refmed curve and surface by using the software, Mathematica. The Chaikin's algorithm is used to refme a curve from an arbitrary control polygon, formed by a set of control points. By repeating the application of Catmull & Clark's algorithm, the limit of a sequence successfully refmed the polyhedral meshes created. Therefore, a visually pleasing refmed surface can be generated.
