Select a subset of the given points that forms a grid.
Name | Type | Range | Description | |
---|---|---|---|---|
inPoints | Point2DArray | |||
inMaxAttempts | Integer* | 1 - | Maximum number of attempts at finding the grid | |
inMaxOutlierCount | Integer* | 0 - | Determines how many outlier points can be present to end the search | |
inMinLength | Real | 0.0 - | Minimum length of a grid segment | |
inMaxLength | Real* | 0.0 - | Maximum length of a grid segment, if set to Auto it will be approximated | |
inMaxLengthRatio | Real | 1.0 - 2.0 | Maximum ratio of two consecutive segments in the grid | |
inAngleRange | Real | 0.0 - 45.0 | Maximum variation of angles between neighbouring grid segments in degrees | |
inBaseAspectRatioRange | Real | 0.0 - 1.0 | Maximum variation of the base aspect ratio (ignores if base aspect ratio is not given) | |
inBaseAspectRatio | Real* | 0.3 - 1.0 | A reference aspect ratio of the grid | |
inBaseShear | Real* | 0.0 - 60.0 | A reference shear angle between grid directions that uses inMaxAngleRange as the maximum error range | |
inBaseOrientation | Real* | 0.0 - 360.0 | A reference orientation of one of the grids directions | |
