API Reference > geometry-core > CartesianGeometry > Vector3d > normalizeWithLength normalizeWithLength Method Return a pair object containing (a) property v which is a unit vector in the direction of the input and (b) property mag which is the magnitude (length) of the input (instance) prior to normalization. If the instance (input) is a near zero length the v property of the output is undefined. normalizeWithLength(result?: Vector3d): { mag: number, v: Vector3d | undefined } Parameter Type Description result Vector3d optional result. Returns - { mag: number, v: Vector3d | undefined } Defined in core/geometry/src/geometry3d/Point3dVector3d.ts Line 725 Last Updated: 13 June, 2024
