XML: Farris Wheel Effect

From FSDeveloper Wiki

[edit] 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.
