ComputeSingleConstantAltitudeCartographicWithWindingOrder Method (IAgStkGraphicsExtrudedPolylineTriangulatorInitializer)
See Also  Example
CentralBody
The central body to compute the extrusion on.
Positions
An array containing the polyline positions that should be extruded, provided in the order latitude, longitude, altitude.
Altitude
The extrusion's constant altitude, in meters, above the ellipsoid.
PositionsWindingOrder
The winding order of positions.

Description

For convenience. Computes an extrusion of positions on the specified centralBody using Cartographic positions. One side of the extrusion has a constant altitude and the other has the original altitudes from positions. Longitude and latitude are in radians, and altitude is in meters. This is equivalent to converting each position in positions to Cartesian and calling Compute Single Constant Altitude

Syntax

[Visual Basic .NET] 
Public Function ComputeSingleConstantAltitudeCartographicWithWindingOrder( _
   ByVal CentralBody As String, _
   ByRef Positions() As Variant, _
   ByVal Altitude As Double, _
   ByVal PositionsWindingOrder As AgEStkGraphicsWindingOrder _
) As IAgStkGraphicsExtrudedPolylineTriangulatorResult

Parameters

CentralBody
The central body to compute the extrusion on.
Positions
An array containing the polyline positions that should be extruded, provided in the order latitude, longitude, altitude.
Altitude
The extrusion's constant altitude, in meters, above the ellipsoid.
PositionsWindingOrder
Member Value Description
eStkGraphicsWindingOrderCounterClockwise 0 Positions or triangles are defined in counter-clockwise order.
eStkGraphicsWindingOrderClockwise 1 Positions or triangles are defined in clockwise order.
eStkGraphicsWindingOrderCompute 2 The winding order is unknown and should be computed. For best performance, only use this value if you do not know the actual winding order.
The winding order of positions.

Example

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