XML: Ferris Wheel Effect
From FSDeveloper Wiki
XML: Ferris Wheel Effect
Most commonly used for labels on compass roses. This effect will keep the label upright, while the compass rotates.
Create your label and position it at 0 degrees, then assign 2 shifts to it. One for the X and one for the Y.
The Y shift script is:
-Radius * cos(heading - compass point)
The X shift is:
-Radius * sin(heading - compass point)
Note that this technique can also be used in GDI+/DirectX displays.
