ComputeWithAltitudesAndWindingOrder 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.
BottomAltitude
The extrusion's bottom altitude, in meters, above the ellipsoid.
TopAltitude
The extrusion's top altitude, in meters, above the ellipsoid.
PositionsWindingOrder
The winding order of positions.





Description

Computes an extrusion of positions on the specified centralBody with a constant bottomAltitude and topAltitude.

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.
BottomAltitude
The extrusion's bottom altitude, in meters, above the ellipsoid.
TopAltitude
The extrusion's top 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 altitudes.
