QuantizedMeshTerrainProviderGetFirstPartials Method (Double, Double)

Get the partial derivatives of height with respect to the specified longitude and latitude relative to the provider's Shape.

Namespace: AGI.Foundation.Terrain
Assembly: AGI.Foundation.TerrainReaders (in AGI.Foundation.TerrainReaders.dll) Version: 24.3.420.0 (24.3.420.0)

Syntax

C++

Copy

public override FirstPartialsOfHeight GetFirstPartials(
	double longitude,
	double latitude
)

Public Overrides Function GetFirstPartials ( 
	longitude As Double,
	latitude As Double
) As FirstPartialsOfHeight

public:
virtual FirstPartialsOfHeight GetFirstPartials(
	double longitude, 
	double latitude
) override

abstract GetFirstPartials : 
        longitude : float * 
        latitude : float -> FirstPartialsOfHeight 
override GetFirstPartials : 
        longitude : float * 
        latitude : float -> 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.

Return Value

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