利用lm库在实现inverse kinematic，能够给定点，使人体的关节点自动符合这些给定的约束-using lm library to realize inverse kinematics, and let the human pose to satisfy the constraints.

Poisson surface reconstruction creates watertight surfaces from oriented point sets. In this work we extend the technique to explicitly incorporate the points as interpolation constraints. The extension can be interpreted as a generalization of
