基于Hermite样条曲线的关键帧插值角色动画

Key Frame Interpolated Character Animation Based on Hermite Spline

针对角色关键帧动画中的运动平滑性问题,以基于运动捕获数据的角色动画为基础,提出以Hermite样条曲线为基本算法结合四元数球面线性插值算法的方法,对虚拟人体骨骼运动的动画关键帧进行插值,实现虚拟人体角色的动作平滑过渡。经实验证明,本方法实现简单高效,获得的关键帧动画平滑流畅,可广泛用于人体类角色动画的研究。

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.
