API Reference > geometry-core > Numerics > Matrix4d > multiplyPoint3dArrayQuietNormalize multiplyPoint3dArrayQuietNormalize Method multiply each matrix * points[i]. This produces a weighted xyzw. Immediately renormalize back to xyz and replace the original point. If zero weight appears in the result (i.e. input is on eyeplane)leave the mapped xyz untouched. multiplyPoint3dArrayQuietNormalize(points: Point3d[]): void Parameter Type Description points Point3d[] Returns - void Defined in core/geometry/src/geometry4d/Matrix4d.ts Line 495 Last Updated: 13 June, 2024
