Compute Method (IAgStkGraphicsSurfacePolygonTriangulatorInitializer)
See Also  Example
CentralBody
The central body to compute the triangulation on.
Positions
An array containing positions (in the order x, y, z) defining the boundary of the polygon, in the centralBody's fixed reference frame, to triangulate.





Description

Computes the triangulation on the specified centralBody for a polygon whose boundary is defined by the specified positions. This is equivalent to calling Compute with an altitude of 0, a granularity of 1 degree, and a positionsWindingOrder of Compute.

Syntax

[Visual Basic .NET] 
Public Function Compute( _
   ByVal CentralBody As String, _
   ByRef Positions As System.Array _
) As IAgStkGraphicsSurfaceTriangulatorResult
[C#] 
public IAgStkGraphicsSurfaceTriangulatorResult Compute(

   string CentralBody, 

   ref System.Array Positions

);
[Managed C++] 
public: IAgStkGraphicsSurfaceTriangulatorResult^ Compute(

   String __gc ^ CentralBody, 

   System::Array ^^ Positions

);
[Java] 
public IAgStkGraphicsSurfaceTriangulatorResult compute(

   String CentralBody, 

   Object[] Positions

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

   BSTR CentralBody, 

   SAFEARRAY ** Positions, 

   IAgStkGraphicsSurfaceTriangulatorResult ** ReturnValue

);

Parameters

CentralBody
The central body to compute the triangulation on.
Positions
An array containing positions (in the order x, y, z) defining the boundary of the polygon, in the centralBody's fixed reference frame, to triangulate.

Example

Shows the format of the Positions and HolePositions parameters when computing using a surface polygon triangulator.
