全息影像shader

不错的效果，代码非常简单，似乎不够完善！

Here is an old gem i posted in the unity3d forums. This shader gives a holographic drawn effect like in star wars or any other sci-fi movies


The Shader Code:


Shader "Hologram" {
Properties {
_MainTex ("Base (RGB)", 2D) = "white" {}
}
SubShader {
Pass {
Tags { "Queue" = "Transparent" "RenderType"="Transparent" }
Fog { Mode Off }
//ZWrite off
//ZTest Less
Blend SrcAlpha OneMinusDstAlpha
AlphaTest GEqual 0.1
LOD 200



CGPROGRAM
#pragma vertex vert
#pragma fragment frag
#include "UnityCG.cginc"



sampler2D _MainTex;



struct v2f {
float4 pos : SV_POSITION;
float alpha;
float2 uv : TEXCOORD0;
};



v2f vert (appdata_base v) {
v2f o;
o.pos = mul(UNITY_MATRIX_MVP, v.vertex);
float3 C = WorldSpaceViewDir(v.vertex);
float3 N = mul(_World2Object, float4(v.normal, 0)).xyz;
float NdotC = dot(N, C);
//Clamp it??
NdotC = clamp(NdotC, 0, 1);
o.uv.x = NdotC;
o.uv.y = 0;
//Use col for alpha
o.alpha = 1-NdotC;
return o;
}



half4 frag( v2f i ) : COLOR {
half4 c = tex2D (_MainTex, i.uv);
c.a = i.alpha;
return c;
}
ENDCG
}
}
FallBack "Diffuse"
}
