Hello guys
I found an error in this code because manhattanDistance need 2 parameter
what would be the second parameter (RGB1 and RGB2)
float dist = smoothstep (0, threshold, manhattanDistance (chromakeyColor, ??????));
float manhattanDistance (float3 RGB1, RGB2 float3)
{
float3 dist3 = abs (RGB 1-RGB2);
return dot (dist3, float3 (1,1,1));
}
float4 chromakey (float3 pixelrgb, float3 chromakeyColor, float threshold)
{
float dist = smoothstep (0, threshold, manhattanDistance (chromakeyColor));
float alpha = 1.0 - saturate (dist);
return float4 (pixelrgb, alpha);
}
Thanks for listening.
