示例1: GetExample9

        public static IGeometry GetExample9()
        {
            const int DensificationDivisions = 20;
            const double MaxDeviation = 0.1;
            const double BaseZ = 0;
            const double OffsetZ = -7;

            //Extrusion: 3D Polyline Having Vertices With Varying Z Values, Extruded Relative To Existing
            //           Vertex Z Values Via ConstructExtrude()

            IPointCollection polylinePointCollection = new PolylineClass();

            polylinePointCollection.AddPoint(GeometryUtilities.ConstructPoint2D(-10, -10), ref _missing, ref _missing);
            polylinePointCollection.AddPoint(GeometryUtilities.ConstructPoint2D(0, -5), ref _missing, ref _missing);
            polylinePointCollection.AddPoint(GeometryUtilities.ConstructPoint2D(0, 5), ref _missing, ref _missing);
            polylinePointCollection.AddPoint(GeometryUtilities.ConstructPoint2D(10, 10), ref _missing, ref _missing);

            IPolyline polyline = polylinePointCollection as IPolyline;
            polyline.Densify(polyline.Length / DensificationDivisions, MaxDeviation);

            IGeometry polylineGeometry = polyline as IGeometry;

            GeometryUtilities.MakeZAware(polylineGeometry);

            Random random = new Random();

            for (int i = 0; i < polylinePointCollection.PointCount; i++)
            {
                IPoint polylinePoint = polylinePointCollection.get_Point(i);

                polylinePointCollection.UpdatePoint(i, GeometryUtilities.ConstructPoint3D(polylinePoint.X, polylinePoint.Y, BaseZ - 2 * Math.Sin(random.NextDouble())));
            }

            ITopologicalOperator topologicalOperator = polylineGeometry as ITopologicalOperator;
            topologicalOperator.Simplify();

            IConstructMultiPatch constructMultiPatch = new MultiPatchClass();
            constructMultiPatch.ConstructExtrude(OffsetZ, polylineGeometry);

            return constructMultiPatch as IGeometry;
        }
