API Reference > geometry-core > CartesianGeometry > Vector3d > rotate90Towards rotate90Towards Method Return a (new or optionally preallocated) vector that is rotated 90 degrees in the plane of this vector and the target vector. rotate90Towards(target: Vector3d, result?: Vector3d): undefined | Vector3d Parameter Type Description target Vector3d Second vector which defines the plane of rotation. result Vector3d optional preallocated vector for result. Returns - undefined | Vector3d rotated vector, or undefined if the cross product of this and the the target cannot be normalized (i.e. if the target and this are colinear) Defined in geometry3d/Point3dVector3d.ts Line 880 Last Updated: 11 June, 2024
