-
computeVisibleFovs
protected boolean computeVisibleFovs(CelestialBody cb, FovCamera fcamera)
Returns true if a body with the given position is observed in any of the given directions using the given cone angle- Parameters:
cb
- The body.fcamera
- The FovCamera.- Returns:
- True if the body is observed. False otherwise.
-
