ComputeEllipseCartographic Method (IAgStkGraphicsSurfaceShapesInitializer)
See Also Example

CentralBody: The central body to compute the ellipse on.

Center: An array containing the center of the ellipse, in the centralBody's fixed reference frame, in the order latitude, longitude, altitude.

MajorAxisRadius: The radius of the ellipse's major axis, in meters.

MinorAxisRadius: The radius of the ellipse's minor axis, in meters.

Bearing: An angle, in radians, measured clockwise from north.

Description

For convenience. Computes boundary positions for an ellipse on the specified centralBody using a Cartographic center. Longitude and latitude are in radians, and altitude is in meters. This is equivalent to converting center to Cartesian and calling Compute Ellipse

Syntax

[Visual Basic .NET]
Public Function ComputeEllipseCartographic( _ ByVal CentralBody As String, _ ByRef Center() As Variant, _ ByVal MajorAxisRadius As Double, _ ByVal MinorAxisRadius As Double, _ ByVal Bearing As Double _ ) As IAgStkGraphicsSurfaceShapesResult

[Visual Basic .NET]

Public Function ComputeEllipseCartographic( _
   ByVal CentralBody As String, _
   ByRef Center() As Variant, _
   ByVal MajorAxisRadius As Double, _
   ByVal MinorAxisRadius As Double, _
   ByVal Bearing As Double _
) As IAgStkGraphicsSurfaceShapesResult

Parameters

CentralBody: The central body to compute the ellipse on.
Center: An array containing the center of the ellipse, in the centralBody's fixed reference frame, in the order latitude, longitude, altitude.
MajorAxisRadius: The radius of the ellipse's major axis, in meters.
MinorAxisRadius: The radius of the ellipse's minor axis, in meters.
Bearing: An angle, in radians, measured clockwise from north.

Example

Shows the format of the Center parameter when computing an ellipse with a cartographic position.
