Unity双相机Camera，将虚拟相机视角画面显示在平面Plane上

Unity双相机Camera，将虚拟相机视角画面显示在平面Plane上

场景中通过添加Render Texture实现

1、场景中新建Render Texture

2、将其拖到相机的Target Texture上

3、新建Plane，将虚拟相机视角画面渲染在上面：将第一步新建的Render Texture直接拖到Plane上

4、运行，相机拍摄的画面被实时显示在Plane上

通过挂脚本实现

将脚本挂在场景中

using UnityEngine;
using System.Collections;
using System.IO;
 
public class GetImage : MonoBehaviour 
{
    public Camera mainCam;           //目标摄像机
    RenderTexture rt;                //声明一个中间变量 
    Texture2D t2d ;
    public GameObject pl;  
 
    void Start () 
    {
        t2d = new Texture2D(800,600,TextureFormat.RGB24,false);
        rt = new RenderTexture(800, 600, 24);
        mainCam.targetTexture = rt;
    }
    
    void Update () 
    {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            pl.GetComponent<Renderer>().material.mainTexture = rt;
            //截图到t2d中
            RenderTexture.active = rt;                    
            t2d.ReadPixels(new Rect(0, 0, rt.width, rt.height), 0, 0);
            t2d.Apply();
            RenderTexture.active = null;
        }          
    }
}
