用Shader实现夜视效果

王者再临

一个独特的效果实现，夜视效果，下面是代码：

1. ////shaer:
   
2. Shader "Hidden/NightVision" {
   
3. Properties {
   
4. _MainTex ("Base (RGB)", 2D) = "white" {}
   
5. }
   
6. SubShader {
   
7. Pass {
   
8. ZTest Always Cull Off ZWrite Off Lighting Off
   
9. Fog { Mode off }
   
10. CGPROGRAM
    
11. #pragma vertex vert_img
    
12. #pragma fragment frag
    
13. #pragma fragmentoption ARB_precision_hint_fastest
    
14. #include "UnityCG.cginc"
    
15. uniform sampler2D _MainTex;
    
16. float4 frag (v2f_img i) : COLOR {
    
17. float4 c = tex2D(_MainTex, i.uv);
    
18. c.b = c.r*2;
    
19. c.g = c.b*2;
    
20. return c;
    
21. }
    
22. ENDCG
    
23. }
    
24. }
    
25. Fallback off
    
26. }
    
27. /////c# code for camera;
    
28. using UnityEngine;
    
29. 
    
30. 
    
31. 
    
32. [ExecuteInEditMode]
    
33. [AddComponentMenu("Image Effects/NightVision")]
    
34. public class NightVision : ImageEffectBase {
    
35. 
    
36. 
    
37. 
    
38. // Called by camera to apply image effect
    
39. void OnRenderImage (RenderTexture source, RenderTexture destination) {
    
40. Graphics.Blit (source, destination, material);
    
41. }
    
42. }
