A hierarchical approach to interactive motion editing for human-like figures

摘要

This paper presents a technique for adapting existing motion of a human-like character to have the desired featrues that are specified by a set of constraints.Thsi problem can be tyupically formulated as a spacetime constraint prolbem.Our approach ocmines a hierarchical curve fitting techique with a new inverse kinemiatics solver.Using the kinematics solver,we cna adjust the ocnfiguratin of an articulated figure to meet the constraints in each frame.Through the fitting technique,the motion displacement of every joint at each constrained rame is interpolated and thus smoothly propagated to frames.
