Transform.InverseTransformPoint 相反变换位置

# [Transform](Transform.html).InverseTransformPoint 相反变换位置

function *TransformPoint* (*position* : [Vector3](../Vector3/Vector3.html)) : [Vector3](../Vector3/Vector3.html)

*Description* 描述

Transforms position from world space to local space. The opposite of [Transform.TransformPoint](Transform.TransformPoint.html).

变换位置从世界坐标到自身坐标。和 [Transform.TransformPoint](Transform.TransformPoint.html) 相反。

Note that the returned position is affected by scale. Use [Transform.InverseTransformDirection](Transform.InverseTransformDirection.html)
if you are dealing with directions.

注意，返回位置不受缩放影响。如果你是处理方向使用 [Transform.InverseTransformDirection](Transform.InverseTransformDirection.html)。

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	public Transform cam = Camera.main.transform;
	public Vector3 cameraRelative = cam.InverseTransformPoint(transform.position);
	public void Awake() {
		if (cameraRelative.z > 0)
			print("The object is in front of the camera");
		else
			print("The object is behind the camera");
	}
}
```

```
// Calculate the transform's position relative to the camera.
//相对于摄像机计算变换的位置
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* 描述

Note that the returned position is affected by scale. Use [Transform.InverseTransformDirection](Transform.InverseTransformDirection.html)
if you are dealing with directions.

Transforms the position x, y, z from world space to local space. The opposite
of [Transform.TransformPoint](Transform.TransformPoint.html).

变换位置 x, y, z 从世界坐标到自身坐标。和 [Transform.TransformPoint](Transform.TransformPoint.html) 相反。
