| Abstract: | Aiming at the smoothness problem in key frame character animation,this paper proposes an interpolation method which is based on Hermite spline curve integrating with quaternion spherical linear interpolation,and implements smoothness transition of character motion via interpolation in the key frames of skeleton motion based on motion capture data.Many experiments demonstrate that this method can be widely used in humanoid animation due to this method is easy and the result of the motion is smooth. |
