Abstract
We present a new method for smoothly interpolating orientation matrices. It is based upon quaternions and a particular construction of upsilon-spline curves. The new method has tension parameters and variable knot (time) spacing which both prove to be effective in designing and controlling key frame animations.

我们提出了一种用于平滑插值方向矩阵的新方法。它基于四元数和一种特殊的Upsilon样条曲线构造。新方法具有张力参数和可变节点（时间）间距，这两者在设计和控制关键帧动画方面都被证明是有效的。
