【英文摘要】 Contraposing the some deficiencies from the algorithm based on quadric error metrics(QEM),such as neglect of some cusp features and excessive simplification in some parts of the model,a QEM based on eigenmatrix was proposed for mesh simplification. Through introducing the curvature and edge length of a vertex into this new QEM to optimize error metrics,the eigenmatrix can easily distinguish the vertexes of a model,improve the error metrics of the vertexes in the areas with obvious geometric features. Therefor...
