标题: 梦幻画面效果Shader
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):
  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 }

  10. CGPROGRAM
  11. #pragma vertex vert_img
  12. #pragma fragment frag
  13. #pragma fragmentoption ARB_precision_hint_fastest
  14. #include "UnityCG.cginc"

  16. uniform sampler2D _MainTex;

  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);

  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. }
