API Reference > geometry-core > CartesianGeometry > ClipUtilities > clipSegmentBelowPlanesXY clipSegmentBelowPlanesXY MethodStatic Clip an interval of a line segment to an array of planes plane normals assumed OUTWARD planeAltitude is typically a tolerance a tolerance distance. positive altitude makes tha plane move in the direction of the unit normal. clipSegmentBelowPlanesXY(planes: Plane3dByOriginAndUnitNormal[], segment0: Readonly<WritableXAndY>, segment1: Readonly<WritableXAndY>, interval: Range1d, signedAltitude: number = 1.0e-14): void Parameter Type Description planes Plane3dByOriginAndUnitNormal[] array of planes segment0 Readonly<WritableXAndY> start of segment segment1 Readonly<WritableXAndY> end of segment interval Range1d Pre-initialized interval of live part of segment signedAltitude number Returns - void Defined in clipping/ClipUtils.ts Line 661 Last Updated: 12 June, 2024
