摘　　要：提出新的三角形折叠误差计算方法,并针对网格简化程度的不同引入阈值控制折叠误差,从而生成满足不同需要三维模型的多个细节层次;提出建立不同细节层次模型间顶点的对应关系,然后在对应点之间进行线性插值的方法,实现了绘制过程中不同细节层次模型间的平滑过渡。Based on LOD algorithm of triangle collapse, a optimal triangle collapse algorithm is proposed, in which threshold is imported according to mesh simplification extent to control collapse error, thus LODs of 3-D model is generated. And more, interpolating algorithm between different LODs is brought forward and smooth transition between different levels of detail of model is accomplished.
