三角网格模型变形设

提出了一种三角网格模型变形算法,采用最小二乘法求解三角网格模型变形设计的参考曲面,将网格顶点向参考曲面投影,建立网格顶点与投影点间的映射关系,通过调整参考曲面控制顶点,根据投影点位移量调整网格顶点坐标,采用三角Bézier曲面理论进行网格模型光顺处理,实例证明该方法可准确控制模型形状,有效提高三角网格模型的光顺性及变形设计效率.

Deformation Design of Triangular Mesh Model

A design algorithm of a triangular mesh model was proposed,that included four steps: first,the reference surface of the triangular mesh model was obtained with least square method;second,the projection point of vertex on mesh was calculated and the mapping relationship of mesh vertex and projection point was built;third,the coordinates of mesh vertexes were changed according to the displacement of projection points when adjusting the control points of reference surface;and fourth,the fairing of mesh model w...
