A Key Frame Interpolation Method Enhancing Motion Details of Skeletal Animation

This paper presents a key frame interpolation method,which can represent swing and variable motion for virtual human animation.Based on motion features of angles between bones,key frames are extracted from captured motion data using curve simplification method.Key frames are classified through motion details,and different interpolation methods are used to compute internal frames for different class.Experiments show that method provided by this paper can simulate arm's swing and variable motion animation.
