Dehui Kong · Jisuanji gongcheng · 2007
This paper presents an improved quadric error metric edge-collapse based algorithm which can keep the speed and efficiency of quadric error metric and reserve more important shape features even after performing drastic level of simplification. It defines an important degree of a triangle and embeds it into the original Garland's quadric error metric, so that the metric can not only measure distance error but also reflect geometric variations of local surface. The experimental results show that the new algorithm can reserve quite a number of important shape features and reduce visual distortion effectively at low levels of detail.
