using UnityEngine;  
using System.Collections;  

public class DetectDeviceList : MonoBehaviour {  

	// Use this for initialization  
	void Start () {  

		WebCamTexture webcamTexture = new WebCamTexture ();  

		//如果有后置摄像头，调用后置摄像头  
		for (int i = 0; i < WebCamTexture.devices.Length; i++) {  
			
			print (WebCamTexture.devices [i].name);

			if (WebCamTexture.devices [i].name == "Creative GestureCam") {  
				webcamTexture.deviceName = WebCamTexture.devices [i].name;  

				break;  
			}  
		}  

		Renderer renderer = GetComponent<Renderer>();  
		renderer.material.mainTexture = webcamTexture;  
		webcamTexture.Play();  
	}  

}  

把相机移到平面的另一侧，同时平面绕x轴旋转90

2， Unity3d，调用摄像头显示

3， 图像水平变换

MirrorFlipCamera.cs 脚本放在相机上，这样是整个视野的图像都会变化

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class MirrorFlipCamera : MonoBehaviour
{
	new Camera camera;
	public bool flipHorizontal;
	void Awake()
	{
		camera = GetComponent<Camera>();
	}
	void OnPreCull()
	{
		camera.ResetWorldToCameraMatrix();
		camera.ResetProjectionMatrix();
		Vector3 scale = new Vector3(flipHorizontal ? -1 : 1, 1, 1);
		//Vector3 scale = new Vector3(1,flipHorizontal ? -1 : 1,  1);
		//Vector3 scale = new Vector3(1,1 , flipHorizontal ? -1 : 1);
		camera.projectionMatrix = camera.projectionMatrix * Matrix4x4.Scale(scale);
	}
	void OnPreRender()
	{
		GL.invertCulling = flipHorizontal;
	}


	void OnPostRender()
	{
		GL.invertCulling = false;
	}
}
