Abstract

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 the new collapse vertex is determined based on certain collapse error and 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.
