dc.description.abstract Polygonal mesh is widely used in computer graphics and related areas. To get highly detailed models, normally huge number of polygons is used. However, in many cases those huge numbers are not necessary or not practical to render. Instead, the simplified versions of models with fewer faces/triangles may be better for use. So far, many different algorithms have been developed for simplifying triangulated object models. In this thesis, a new polygonal mesh simplification algorithm is proposed and implemented based on a vertex decimation approach. The novelty in this method lies both in the cost function used to select a vertex for decimation as well in the heuristics applied to re-triangulate the resulting hole. Vertices are initially classified as hyperbolic or non-hyperbolic and a volume cost associated with each non-hyperbolic vertex based upon its local geometry. Our strategy to re-triangulate a hole improves existing methods in terms of being faithful to the original shape. We have implemented our algorithm and experiments indicate a performance comparable with the best current mesh simplification algorithms. en_US
