An Improved Algorithm of Model Simplification Based on Triangle Collapse

This paper presents an improved algorithm based on triangle collapse.From calculating the maximum distance between the vertexes and their related average plane for each triangle,and based on the triangle area,surface attribute and the predefined characteristics,the algorithm gives out the triangle's weight,the collapse orders of triangle and makes a continuous level of detail model. This algorithm can not only keep the characteristics of the model but also compute on high speed.
