Shader - Video Loss Quality
Hi all!
I have a question I haven't been able to solve or found an online forum/answer for it.
I am building a 360video AR portal and have some 360º videos with pretty good quality. I have my video on a sphere that has a material applied to it with a custom shader. All works great but the video seems to loose a lot of quality and becomes a bit blurry. I understand this is caused by the shader but I am not sure how to fix or find a solution for it.
Any help will be appreciated!
Here's the shader I am using:
Shader "Custom/Equirectangular" { Properties { _Color ("Main Color", Color) = (1,1,1,1) _MainTex ("Diffuse (RGB) Alpha (A)", 2D) = "gray" {} [Enum(Equal,3,NotEqual,6)] stest ("STENCILTEST", int) = 3
}
SubShader{
Pass {

float3 normal : NORMAL;
};

float3 normal : TEXCOORD0;
};
v2f vert (appdata v)

v2f o;
o.pos = UnityObjectToClipPos(v.vertex);
o.normal = v.normal;
return o;
}

#define PI 3.141592653589793
inline float2 RadialCoords(float3 a_coords)
{
float3 a_coords_n = normalize(a_coords);
float lon = atan2(a_coords_n.z, a_coords_n.x);
float lat = acos(a_coords_n.y);
float2 sphereCoords = float2(lon, lat) * (1.0 / PI);
return float2(sphereCoords.x * 0.5 + 0.5, 1 - sphereCoords.y);
}
float4 frag(v2f IN) : COLOR
{
float2 equiUV = RadialCoords(IN.normal);
return tex2D(_MainTex, equiUV);
}
ENDCG
