Description 描述

OnRenderImage is called after all rendering is complete to render image

当完成所有渲染图像后被调用，用来渲染图像后期效果。

postprocessing effects (Unity Pro only).

后期效果处理(仅Unity Pro)。

It allows you to modify final image by processing it with shader based filters. The incoming image is source render texture. The result should end up in destinationrender texture. When there are multiple image filters attached to the camera, they process image sequentially, by passing first filter's destination as the source to the next filter.

它允许你使用基于着色器的过滤器来处理最终的图像。输入的图像是源渲染纹理，结果是目标渲染纹理。当有多个图像过滤器附加在相机上时，它们序列化地处理图片，将第一个过滤器的目标作为下一个过滤器的源。

This message is sent to all scripts attached to the camera.

这个消息被发送到所有附加在相机上的脚本。

JavaScript:

var mat: Material;
 
function OnRenderImage(src: RenderTexture, dest: RenderTexture) {
	// Copy the source Render Texture to the destination,
	// applying the material along the way.
	Graphics.Blit(src, dest, mat);
}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public Material mat;
    void OnRenderImage(RenderTexture src, RenderTexture dest) {
        Graphics.Blit(src, dest, mat);
    }
}
