Public Function GetFirstPartials ( 
	longitude As Double,
	latitude As Double,
	interpolator As TerrainInterpolator(Of QuantizedMeshTerrainTile)
) As FirstPartialsOfHeight

public:
FirstPartialsOfHeight GetFirstPartials(
	double longitude, 
	double latitude, 
	TerrainInterpolator<QuantizedMeshTerrainTile^>^ interpolator
)

member GetFirstPartials : 
        longitude : float * 
        latitude : float * 
        interpolator : TerrainInterpolator<QuantizedMeshTerrainTile> -> FirstPartialsOfHeight

Parameters

longitude: Type: SystemDouble
The longitude, in radians. Requesting derivatives for a longitude less than -π or greater than π will always return NaN.
latitude: Type: SystemDouble
The latitude, in radians. Requesting derivatives for a latitude less than -π/2 or greater than π/2 will always return NaN.
interpolator: Type: AGI.Foundation.TerrainTerrainInterpolatorQuantizedMeshTerrainTile
The interpolator to use when computing the value of the partial derivatives inside the boundary.

Return Value

Type: FirstPartialsOfHeight
The FirstPartialsOfHeight with respect to longitude and latitude, in meters of height per radian.
