Parameters

Name Type Range Default Description
inSurfaceAvlNet.SurfaceSurface to fit the circle to.
inFittingMapAvlNet.CircleFittingMapInput fitting map.
inEdgeScanParamsAvlNet.EdgeScanParams3DParameters controlling the edge extraction process.
inEdgeSelectionAvlNet.Selectionavl::SelectionBestSelection mode of edges. Default value: avl::SelectionBest.
inLocalBlindnessAvlNet.LocalBlindness?Defines conditions in which weaker edges can be detected in the vicinity of stronger edges. Default value: atl::NIL.
inMaxProfileGapWidthint?<0, INF>1Maximal number of consecutive not existing profile points. Default value: 1.
inMaxIncompletenessfloat<0.0f, 0.999f>0.1fMaximal fraction of edge points not found. Default value: 0.1f.
inFittingMethodAvlNet.CircleFittingMethodAlgebraicTaubinMethod used to fit a circle. Default value: AlgebraicTaubin.
inOutlierSuppressionAvlNet.MEstimator?Selects a method for ignoring incorrectly detected points. Default value: atl::NIL.
outCircleAvlNet.INullable<AvlNet.Circle3D>Fitted circle or nothing if the fitting fails. This parameter cannot be null.
outEdgesAvlNet.NullableRef<System.Collections.Generic.List<AvlNet.SurfaceEdge1D?>>Found edges. Can be null to skip this parameter calculation.
outDeviationProfileAvlNet.NullableRef<AvlNet.NullableRef<AvlNet.Profile>>Profile of distances between the actual circle points and the corresponding reference circle points. Can be null to skip this parameter calculation.
outInliersAvlNet.NullableRef<System.Collections.Generic.List<AvlNet.Point3D>>Points matching the fitting Circle. Can be null to skip this parameter calculation.
outHeightProfilesAvlNet.NullableRef<AvlNet.SafeList<AvlNet.Profile>>Extracted surface height profiles. Can be null to skip this parameter calculation.
outResponseProfilesAvlNet.NullableRef<AvlNet.SafeList<AvlNet.Profile>>Profiles of the edge (derivative) operator response. Can be null to skip this parameter calculation.
