摘要
提出了一种新的三角形折叠误差计算方法,针对网格简化程度的不同引入阈值控制折叠误差,生成满足不同需要三维模型的多个细节层次;提出通过建立不同细节层次模型间顶点的对应关系,在对应点之间进行线性插值,以此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, an optimal triangle collapse algorithm was proposed, in which threshold was introduced according to mesh simplification extent to control collapse error, thus LODs of 3-D model was generated. Moreover, interpolating algorithm between different LODs was brought forward and smooth transition between different levels of detail of model was accomplished.
