Since the lengths of the line segments and the angles between line segments are treated as representation parameters, it is convenient to construct energy function and to deal with displacement and length constraints. Based on this advantage, a parametrical model for human body is proposed, which can easily produce human body models with different feature sizes. The above method is just suitable for polylines. Therefore, a generic deformation method for both discrete curves and surfaces is presented. The energy function is constructed by analyzing the relationship of the points before and after deformation. Together with the displacement constraints, the deformation problem is converted to a convex quadratic programming. A necessary condition for constraint points and a sufficient condition for the uniqueness of solution are given. The proposed method can be combined with skeleton-driven animation to control the deformation.

将线段长度与线段之间的角度作为表示参数,既有利于能量函数的构造,又便于处理位移约束和长度内蕴约束条件,利用这一优势,将其应用于三维人体的参数化建模,可以方便地产生具有不同特征尺寸参数的人体模型,由于这种方法只适用于折线变形,具有较大局限性,因此,本文进一步提出一种较通用的离散曲线曲面变形方法,通过分析变形前后的位置关系来构造能量函数,再加上位移约束条件,将变形问题转化为一个凸二次规划问题,并且给出了约束点应满足的必要条件及模型解唯一的充分条件,这种方法还可以与骨架驱动变形的思想相结合,能更好的控制变形。
