Based on the modeling of the sky, two improved methods were proposed: rotate the coordinate system of the sphere, and modify the coordinate of the texture.

针对于天空的建模，提出了两种改进方法：旋转球面坐标系法和修改纹理坐标法。

When you select an object and press TKEY, you get the option to visually scale and move the texture space, but not to rotate the texture.

当你选择一个对象并按下TKEY键，你就可以选择缩放和移动纹理，但是不能旋转纹理。
