A standard parametrization for elements of is in terms of 3 “Euler angles” with a general rotation given by
i.e., first a rotation about the z-axis by an angle then a rotation by an angle about the new x-axis, followed by a rotation by about the new axis. Multiplying out the matrices gives a rather complicated expression for a rotation in terms of the three angles, and one needs to figure out what range to choose for the angles to avoid multiple counting.

机器草稿中的相关讨论摘录
中元素的一种标准参数化是借助 3 个“欧拉角” 来表示,其中一般旋转由下式给出
即,首先绕轴旋转角度,然后绕新的轴旋转角度,接着绕新的轴旋转。将矩阵乘开后会得到一个用三个角表示的相当复杂的旋转表达式,并且需要弄清楚应选择什么值域来避免重复计数。
