OnRenderImage 在图像的所有渲染操作全部完成后调用。
后期处理效果。
该函数让您能够使用基于着色器的过滤器对最终图像进行处理,从而修改最终图像。
传入的图像为 source
渲染纹理。结果应以
destination
渲染纹理结束。如果您重写该方法,则必须始终发出 Graphics.Blit() 或渲染一个全屏四边形。
当摄像机附加了多个图像过滤器时,
它们按顺序依照下述方法对图像进行处理:将第一个过滤器的目标作为源传递给下一个过滤器,依此类推。
该消息将发送到附加到摄像机的所有脚本。
另请参阅:编写后期处理效果。
using UnityEngine;
public class Example : MonoBehaviour { Material material;
void OnRenderImage(RenderTexture source, RenderTexture destination) { // Copy the source Render Texture to the destination, // applying the material along the way. Graphics.Blit(source, destination, material); } }
