Inspired in part by psonice's lo-fi analogue processing, I tried doing some lo-fi digital processing: Bayer Dithering, as a CoreImage filter.

The most exciting part is that CoreImage doesn't support Arrays, Data-dependent Conditionals, or the Boolean "&&" operator.. But it's kinda possible to implement it, using some huge Lisp-style expressions.

For example, for a 4x4 Bayer, I'm doing this:

float bayerColor(float colorin,int bx,int by,float BayerIntensity)
{
   float mul =
       by==0 ?
         ( bx==0 ?  1.0/17.0 : ( bx==1 ?  9.0/17.0 : ( bx==2 ?  3.0/17.0 : 11.0/17.0 ) ) ) :
      (by==1 ?
         ( bx==0 ? 13.0/17.0 : ( bx==1 ?  5.0/17.0 : ( bx==2 ? 15.0/17.0 :  7.0/17.0 ) ) ) :
      (by==2 ?
         ( bx==0 ?  4.0/17.0 : ( bx==1 ? 12.0/17.0 : ( bx==2 ?  2.0/17.0 : 10.0/17.0 ) ) ) :
         ( bx==0 ? 16.0/17.0 : ( bx==1 ?  8.0/17.0 : ( bx==2 ? 14.0/17.0 :  6.0/17.0 ) ) )
         ));
 
   return colorin * (mul * 2.0 * BayerIntensity + (1.0 - BayerIntensity));
}
 
kernel vec4 bayerPixel(sampler Image,float BayerIntensity)
{
   vec4 pixel=sample(Image, samplerCoord(Image));
   int bx=mod(samplerCoord(Image).x,4.0);
   int by=mod(samplerCoord(Image).y,4.0);
 
   pixel.r = bayerColor(pixel.r,bx,by,BayerIntensity);
   pixel.g = bayerColor(pixel.g,bx,by,BayerIntensity);
   pixel.b = bayerColor(pixel.b,bx,by,BayerIntensity);
   return pixel;
}

Challenge for the reader: figure out a better way to do this. :^)
