Improved motion path editing
一种改进的运动路径编辑方法

Motion path editing was introduced, A new algorithm which kept the velocity of foot movement unchanged was put forward to solve the footstep sllp in editing process. In this algorithm, constraint technique was used. First, location of foot was computed in every frame as initial constraint. When the motion path was changed, constraints were updated automatically according to the principle of unchanged velocity of foot movement, This automatic method reduces the manual interference existing in traditional ones. Then per-frame Inverse Kinematics algorithm was used to solve foot-constraints in real time, Experimental results show that the proposed algorithm solves footstep slip effectively.
