Methods
-
interpolateUsingFraction
-
Provides the location of a point at the indicated portion along the geodesic.
Parameters:
Name Type Description fractionNumber The portion of the distance between the initial and final points. Returns:
Cartographic The location of the point along the geodesic. -
interpolateUsingSurfaceDistance
-
Provides the location of a point at the indicated distance along the geodesic.
Parameters:
Name Type Description distanceNumber The distance from the inital point to the point of interest along the geodesic Throws:
DeveloperError : start and end must be set before calling funciton interpolateUsingSurfaceDistanceReturns:
Cartographic The location of the point along the geodesic. -
setEndPoints
-
Sets the start and end points of the geodesic
Parameters:
Name Type Description startCartographic The initial planetodetic point on the path. endCartographic The final planetodetic point on the path.
