浮雕效果shader,post processing emboss shader

晃晃

浮雕效果shader，好像不太常用到这种效果，下面是代码:
Shader "Hidden/Emboss" {
Properties {
_MainTex ("Base (RGB)", 2D) = "white" {}
}
SubShader {
Pass {
ZTest Always Cull Off ZWrite Off Lighting Off
Fog { Mode off }
CGPROGRAM
#pragma vertex vert_img
#pragma fragment frag
#pragma fragmentoption ARB_precision_hint_fastest
#include "UnityCG.cginc"
uniform sampler2D _MainTex;
float4 frag (v2f_img i) : COLOR {
float4 c = tex2D(_MainTex, i.uv);
c -= tex2D(_MainTex, i.uv+0.001)*2.0;
c += tex2D(_MainTex, i.uv-0.001)*2.0;
c.rgb = (c.r+c.g+c.b)/3.0;
return c;
}
ENDCG
}
}
Fallback off
}
////////c#code for camera:
using UnityEngine;



[ExecuteInEditMode]
[AddComponentMenu("Image Effects/Emboss")]
public class Emboss : ImageEffectBase {



// Called by camera to apply image effect
void OnRenderImage (RenderTexture source, RenderTexture destination) {
Graphics.Blit (source, destination, material);
}
}
