摘　　要：当前经由商业软件生产出来的三维模型大多存在悬浮的情况,严重影响模型美观及质量,而人工处理则费时费力。文章以空间索引及图算法为基础,经过模型组成部件间的连通性分析,实现悬浮物的批量删除处理。At present,most 3D models produced by commercial software are suspended,which seriously affects the appearance and quality of the model,and manual processing is time-consuming and laborious.Based on the spatial index and graph algorithm,this paper analyzes the connectivity between the components of the model and realizes the batch removal of suspended solids.

关 键 词：RTree 图算法 悬浮物删除
