Expand description
In Flatland, the +X axis is to the right and +Y axis is down. There is no notion of a Z axis. Due to the lack of a Z axis, there is no mathematical notion of “handedness” (either right or left) with respect to rotation. Thus, we define a counter-clockwise rotation in the same way as if a skeuomorphic clock were to be displayed on the screen, with the hands of said clock moving in a CCW motion from the POV of the observer.
