![使用 tikz 进行有限旋转](https://linux22.com/image/463233/%E4%BD%BF%E7%94%A8%20tikz%20%E8%BF%9B%E8%A1%8C%E6%9C%89%E9%99%90%E6%97%8B%E8%BD%AC.png)
凭借我对 tikz 的基本了解,我想在我的课堂笔记中加上有限旋转不是交换的。这是我的代码。

然而,这需要大量的手工工作,结果可能会更令人满意。任何帮助都将不胜感激。
答案1
Tikz-3dplot 使旋转更容易,但有一定的限制。主坐标对应于 POV 的纬度和经度,因此 z 轴始终向上(或向下)。旋转的坐标很容易绕 y 轴或 z 轴旋转,但绕 x 轴旋转需要三次旋转。
这是为了演示可用的旋转,而不是交换性质。
