在四元数表示下导出了两个旋转之间差异的一种简单形式,将人体各关节上总的旋转变化作为帧间距,设计了一种从运动捕获数据中提取关键帧的高效算法。-In quaternion derived under express the difference between the two rotating a simple form of the body of the rotary joint on the total change as the frame spacing, the design of a motion capture data from the key frame extraction algorithm efficient.
