When rotating the view, it seems that the coordinates X and Y are reversed. Is there a display problem?

Answer

The described effect is not a display error, but only a question of perspective and a good example of an optical illusion. It depends on whether you perceive the representation of the axis system as an inner or outer corner.

Example: Rubik's Cube in Isometric View

The yellow side of the cube is the top surface. In the preset isometric view, you can see the inner corner of the coordinate system diagonally from above. If you simply turn the view upside down, so that Z points upwards, X to the right, and Y to the left, you can look at the bottom side of the cube, that is from above on the lower outer corner of the coordinate system.

If you rotate the view by 45 ° about the horizontal axis, you may get the impression that you look at the inner corner of the coordinate system. However, this is the outer corner.
