梦幻画面效果Shader

王者再临

此shader效果未经实际测试，朋友们可以测试下！

Here is shader file (save as Dream.shader in your assets folder):

psi">

1. Shader "Hidden/Dream" {
   
2. Properties {
   
3. _MainTex ("Base (RGB)", 2D) = "white" {}
   
4. }
   
5. SubShader {
   
6. Pass {
   
7. ZTest Always Cull Off ZWrite Off
   
8. Fog { Mode off }
   
9. 
   
10. CGPROGRAM
    
11. #pragma vertex vert_img
    
12. #pragma fragment frag
    
13. #pragma fragmentoption ARB_precision_hint_fastest
    
14. #include "UnityCG.cginc"
    
15. 
    
16. uniform sampler2D _MainTex;
    
17. 
    
18. float4 frag (v2f_img i) : COLOR {
    
19. float4 c = tex2D(_MainTex, i.uv);
    
20. c += tex2D(_MainTex, i.uv+0.001);
    
21. c += tex2D(_MainTex, i.uv+0.003);
    
22. c += tex2D(_MainTex, i.uv+0.005);
    
23. c += tex2D(_MainTex, i.uv+0.007);
    
24. c += tex2D(_MainTex, i.uv+0.009);
    
25. //c += tex2D(_MainTex, i.uv+0.011);
    
26. 
    
27. c += tex2D(_MainTex, i.uv-0.001);
    
28. c += tex2D(_MainTex, i.uv-0.003);
    
29. c += tex2D(_MainTex, i.uv-0.005);
    
30. c += tex2D(_MainTex, i.uv-0.007);
    
31. c += tex2D(_MainTex, i.uv-0.009);
    
32. //c += tex2D(_MainTex, i.uv-0.011);
    
33. c.rgb = float3((c.r+c.g+c.b)/3.0);
    
34. c = c / 9.5;
    
35. return c;
    
36. }
    
37. ENDCG
    
38. }
    
39. }
    
40. Fallback off
    
41. }
    
42. here is code to be attached to camera (save as dream.cs):
    
43. using UnityEngine;
    
44. [ExecuteInEditMode]
    
45. [AddComponentMenu("Image Effects/Dream")]
    
46. public class Dream : ImageEffectBase {
    
47. // Called by camera to apply image effect
    
48. void OnRenderImage (RenderTexture source, RenderTexture destination) {
    
49. Graphics.Blit (source, destination, material);
    
50. }
    
51. }
