xray.ji.water on GPU with jit.gl.pix


    May 01 2012 | 3:00 pm
    Hello all,
    it's 4 days that I'm working on this patch and it's almost working but i need your help to finish it,
    I'm trying to port on GPU the nice Wesley Smith object X-ray.jit.water object
    but there is an error I don't know where
    here's the code of the object and after my patch,
    can anyone help me to finish this patch?
    Thank you

    NOTE: starting from a single white pixel the first iteration gives same result of X-ray.jit.water but from second iteration the result is different.
    for(j=1; j < width-1; j++) {
    fop[j] = fip1[j] + dampFactor*(fip1[j] - prev_fp[j] )
    - timeSpaceFactor*fip2[j]*(4*fip1[j] - fip1[j-1] - fip1[j+1] - fip1_up[j] - fip1_down[j]
    + 0.5*(4*fip1[j] - fip1_up[j-1] - fip1_up[j+1] - fip1_down[j-1] - fip1_down[j+1] ));
    CLIP(fop[j], -1, 1);
    }

      Ok, I found the error, the iteration need 2 time past.
      Here I share my patch x.ray.jit.water porting on jit.gl.pix
      it's not perfect but works ;)
      hope someone can use it as starting point.
      Bye
