ComputeSingleConstantAltitude Method (IAgStkGraphicsExtrudedPolylineTriangulatorInitializer)
See Also  Example
CentralBody
The central body to compute the extrusion on.
Positions
An array containing the polyline positions (in the order x, y, z), in the centralBody's fixed reference frame, that should be extruded.
Altitude
The extrusion's constant altitude, in meters, above the ellipsoid.





Description

Computes an extrusion of positions on the specified centralBody. One side of the extrusion has a constant altitude and the other has the original altitudes from positions. This is equivalent to calling Compute Single Constant Altitude with a positionsWindingOrder of Compute.

Syntax

[Visual Basic .NET] 
Public Function ComputeSingleConstantAltitude( _
   ByVal CentralBody As String, _
   ByRef Positions As System.Array, _
   ByVal Altitude As Double _
) As IAgStkGraphicsExtrudedPolylineTriangulatorResult
[C#] 
public IAgStkGraphicsExtrudedPolylineTriangulatorResult ComputeSingleConstantAltitude(

   string CentralBody, 

   ref System.Array Positions, 

   double Altitude

);
[Managed C++] 
public: IAgStkGraphicsExtrudedPolylineTriangulatorResult^ ComputeSingleConstantAltitude(

   String __gc ^ CentralBody, 

   System::Array ^^ Positions, 

   double Altitude

);
[Java] 
public IAgStkGraphicsExtrudedPolylineTriangulatorResult computeSingleConstantAltitude(

   String CentralBody, 

   Object[] Positions, 

   double Altitude

);
[Unmanaged C++] 
public: HRESULT ComputeSingleConstantAltitude(

   BSTR CentralBody, 

   SAFEARRAY ** Positions, 

   double Altitude, 

   IAgStkGraphicsExtrudedPolylineTriangulatorResult ** ReturnValue

);

Parameters

CentralBody
The central body to compute the extrusion on.
Positions
An array containing the polyline positions (in the order x, y, z), in the centralBody's fixed reference frame, that should be extruded.
Altitude
The extrusion's constant altitude, in meters, above the ellipsoid.

Example

Shows the format of the Positions parameter when computing using an extruded polyline triangulator.
