public function InverseTransformPoint(position: Vector3): Vector3;
public Vector3 InverseTransformPoint(Vector3 position);
public def InverseTransformPoint(position as Vector3) as Vector3

Description

Transforms position from world space to local space. The opposite of Transform.TransformPoint.

Note that the returned position is affected by scale. Use Transform.InverseTransformDirection if you are dealing with directions.

	// Calculate the transform's position relative to the camera.

var cam = Camera.main.transform; var cameraRelative = cam.InverseTransformPoint(transform.position); if (cameraRelative.z > 0) print ("The object is in front of the camera"); else print ("The object is behind the camera");

Description

Transforms the position x, y, z from world space to local space. The opposite of Transform.TransformPoint.

Note that the returned position is affected by scale. Use Transform.InverseTransformDirection if you are dealing with directions.

	// Calculate the world origin relative to this transform.
