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

here's the code of the object and after my patch,

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.

                    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);

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?

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] ));

xray-ji-water-on-gpu-with-jit-gl-pix

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

hope someone can use it as starting point.

P.S. Some admin can change the thred title to "[SHARE] xray.jit.water on GPU with jit.gl.pix"?

I'm interested in trying your patch, but I can't get it to work...

Hi Micron,
I'm interested in trying your patch, but I can't get it to work...
Any idea why ?
