API Reference > geometry-core > CartesianGeometry > Point3dArray > computeConvexHullXY computeConvexHullXY MethodStatic Computes the hull of the XY projection of points. Returns the hull as an array of Point3d Optionally returns non-hull points in insidePoints[] If both arrays empty if less than 3 points. computeConvexHullXY(points: Point3d[], hullPoints: Point3d[], insidePoints: Point3d[], addClosurePoint: boolean = false): void Parameter Type Description points Point3d[] hullPoints Point3d[] insidePoints Point3d[] addClosurePoint boolean Returns - void Defined in geometry3d/PointHelpers.ts Line 798 Last Updated: 11 June, 2024
