Static Private steps

▪ steps: (Anonymous function)[] = [ replacements => Polygon3DFixing._allPolygonsStep(replacements, polygon => new FilterPolygonEdgeCycles(FilterDegeneratedEdges.execute).execute(polygon), ), replacements => Polygon3DFixing._allPolygonsStep(replacements, polygon => new FilterPolygonEdgeCycles(FilterCollinearEdges.execute).execute(polygon), ), replacements => Polygon3DFixing._allPolygonsStep(replacements, polygon => FixTouchingCycles.execute(polygon)), replacements => Polygon3DFixing._allPolygonsStep(replacements, polygon => { if (MeshValidation.vectorCycleIsDegenerated(polygon[0])) { return null; } return polygon.filter(cycle => !MeshValidation.vectorCycleIsDegenerated(cycle)); }), replacements => { const allPoints: Vector3[] = flattenDeep(Array.from(replacements.values())).filter(p => p != null) as Vector3[]; Polygon3DFixing._allPolygonsStep(replacements, polygon => AddCollinearPoints.execute(polygon, allPoints)); }, ]

When adding new cleaning step remember to add it to this array.

Methods

Static Private _allPolygonsStep

▸ _allPolygonsStep(replacements: Map‹ReadonlyVectorPolygon3D, VectorPolygon3D | null›, polygonFunc: function): void

Defined in src/util/Polygon3DFixing/Polygon3DFixing.ts:68

Parameters:

▪ replacements: Map‹ReadonlyVectorPolygon3D, VectorPolygon3D | null›

▪ polygonFunc: function

▸ (ReadonlyVectorPolygon3D: any): VectorPolygon3D | null

Parameters:

Name	Type
ReadonlyVectorPolygon3D	any

Returns: void

---

Static fixPolygon

▸ fixPolygon(polygon: ReadonlyVectorPolygon3D): ReadonlyVectorPolygon3D | null

Defined in src/util/Polygon3DFixing/Polygon3DFixing.ts:63

Parameters:

Name	Type
polygon	ReadonlyVectorPolygon3D

Returns: ReadonlyVectorPolygon3D | null

---

Static fixPolygons

▸ fixPolygons(polygons: ReadonlyVectorPolygon3D[]): VectorPolygon3D[]

Defined in src/util/Polygon3DFixing/Polygon3DFixing.ts:47

Fixes polygons. Does not care about identities, hence returns an array containing all new polygons. Applies various filter to the polygons. Changes their identities, hence returns a map from old to new polygons. Map contains null if the polygon vanished (e.g. it degenerated).

Parameters:

Name	Type	Description
polygons	ReadonlyVectorPolygon3D[]	-

Returns: VectorPolygon3D[]

---

Static fixPolygonsWithReplacements

▸ fixPolygonsWithReplacements(polygons: ReadonlyVectorPolygon3D[]): Map‹ReadonlyVectorPolygon3D, VectorPolygon3D | null›

Defined in src/util/Polygon3DFixing/Polygon3DFixing.ts:52

Parameters:

Name	Type
polygons	ReadonlyVectorPolygon3D[]

Returns: Map‹ReadonlyVectorPolygon3D, VectorPolygon3D | null›
