signedRadiansTo Method

Return the angle in radians (not as strongly-typed Angle) from this vector to vectorB, measured in their containing plane whose normal lies in the same half-space as vectorW.

  • The returned angle is between -Math.PI and Math.PI.
  • If the cross product of this vector and vectorB lies on the same side of the plane as vectorW, this function returns radiansTo(vectorB); otherwise, it returns -radiansTo(vectorB).
  • vectorW does not have to be perpendicular to the plane.
  • Use planarRadiansTo to measure the angle between vectors that are projected to another plane.

signedRadiansTo(vectorB: Vector3d, vectorW: Vector3d): number

Parameter Type Description
vectorB Vector3d target vector.
vectorW Vector3d determines the side of the plane in which the returned angle is measured

Returns - number
