摘　　要：利用种子生长算法获取模型拟提取骨架局部区域,然后在局部区域首尾处交互确定出初始截平面,并自动插值出中间的等分截平面,最后求解几何截面与局部区域网格的截交线,将截交线的几何中心(即骨架点)顺序连接即生成局部骨架。实验表明该方法将人机交互与自动插值相结合生成截平面,算法简单,交互方便,易于控制,并且得出的模型局部骨架较精确。In view of the traditional method of extracting skeleton process cumbersome, complex, the paper presents an interaction method of partial skeleton extraction for three - dimensional mesh model. Firstly, it extracts facets and vertexes for the partial of the three - dimensional mesh model; It makes the geometric cross - sections on the feature points and the aliquot angle ; Then, the paper calculated the intersecting lines and skeleton points ; It achieves the accurate extraction of a partial skeleton model and is si proved to be a method le. The paper presents some partial skeleton extraction instances, which is for the effective and the feasibility.
