Highly detailed geometric models are rapidly becoming common-place in computer graphics. But sometimes it is often desirable to use approximations in place of excessively detailed models to control processing time. This paper introduces a surface simplification algorithm that based on edge-collapse. The algorithm uses Quadric Error Metrics to confirm the position of new vertex in order to control the error, and gives a new cost function of the edge cost. This algorithm can preserve the important feature of original 3D model efficiently and control the error effectively. The results show that t...
