Inversion of the coordinates by rotation
The origin of the figure is at (0,0)

3 dimensional rotation
Inversion of the coordinates (
x with
y
) from the lefthand
figure to the righthand cannot be
done by a simple rotation
in the plane, as shown in the next
animation.
One needs a rotation in 3-dimensional space!
The simplest solution is an upside down rotation
about the
dashed diagonal line, between the
x and y
axes .
