numpy-quaternion库提供了球面线性插值(SLERP)的功能,可以用来平滑地在两个四元数之间过渡: # 两个四元数q1=quaternion(0,0,1,0)# 表示绕x轴旋转90度q2=quaternion(1,0,0,0)# 单位四元数,表示无旋转# 插值t=0.5# 插值参数,范围从0到1intermediate_q=quaternion.slerp(q1,q2,t) 转换矩阵 四元数可以转...
Python numpy Quaternion Python3 Posted at 2019-12-13 はじめにPythonでクォータニオンを扱うライブラリはpyquaternionとnumpy-quaternionが世界でのトップ2のようですが,日本ではpyquaternionの参考ページを作った人が最初にいたからか,巷に溢れているPythonでのクォータニオン計算はpyquaternionばっか...
