ComputeWithHoleAltitudeAndGranularity 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.
HolePositions
An array containing positions (in the order x, y, z) defining the hole in the polygon, in the centralBody's fixed reference frame.
Altitude
The altitude of the triangulation. When 0, the mesh is computed to conform to the ellipsoid.
Granularity
The angular separation, in radians, of positions in the triangulation. Lower granularities are more precise but create more triangles.

Description

Computes the triangulation on the specified centralBody for a polygon whose boundary is defined by the specified positions with a hole specified by holePositions.

Syntax

[Visual Basic .NET]
Public Function ComputeWithHoleAltitudeAndGranularity( _
   ByVal CentralBody As String, _
   ByRef Positions() As Variant, _
   ByRef HolePositions() As Variant, _
   ByVal Altitude As Double, _
   ByVal Granularity As Double _
) As IAgStkGraphicsSurfaceTriangulatorResult

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.
HolePositions
An array containing positions (in the order x, y, z) defining the hole in the polygon, in the centralBody's fixed reference frame.
Altitude
The altitude of the triangulation. When 0, the mesh is computed to conform to the ellipsoid.
Granularity
The angular separation, in radians, of positions in the triangulation. Lower granularities are more precise but create more triangles.

Example

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