Parameters

Name Type Range Default Description
inPointsSystem.Collections.Generic.IList<FilNet.Point2D>
inMaxAttemptsint?<1, INF>Maximum number of attempts at finding the grid. Default value: ftl::NIL.
inMaxOutlierCountint?<0, INF>Determines how many outlier points can be present to end the search. Default value: ftl::NIL.
inMinLengthfloat<0.0f, INF>0.0fMinimum length of a grid segment. Default value: 0.0f.
inMaxLengthfloat?<0.0f, INF>10.0fMaximum length of a grid segment, if set to Auto it will be approximated. Default value: 10.0f.
inMaxLengthRatiofloat<1.0f, 2.0f>1.3fMaximum ratio of two consecutive segments in the grid. Default value: 1.3f.
inAngleRangefloat<0.0f, 45.0f>16.0fMaximum variation of angles between neighbouring grid segments in degrees. Default value: 16.0f.
inBaseAspectRatioRangefloat<0.0f, 1.0f>0.3fMaximum variation of the base aspect ratio (ignores if base aspect ratio is not given). Default value: 0.3f.
inBaseAspectRatiofloat?<0.3f, 1.0f>1.0fA reference aspect ratio of the grid. Default value: 1.0f.
inBaseShearfloat?<0.0f, 60.0f>0.0fA reference shear angle between grid directions that uses inMaxAngleRange as the maximum error range. Default value: 0.0f.
inBaseOrientationfloat?<0.0f, 360.0f>A reference orientation of one of the grids directions. Default value: ftl::NIL.
outPointGridSystem.Collections.Generic.IList<FilNet.Point2D>Detected grid.
diagValidSubgraphSystem.Collections.Generic.IList<FilNet.Segment2D>Graph forming a valid grid.
diagMaxLengthfloatMax length computed by the filter (applicable if inMaxLength is set to Auto).
