Still experimenting with converting bitmaps to topological wireframe renders. :)

No; still experimenting with the flow. Believe I have a consistent formula for the flow now. For this render, I just used the convolution result (desaturated after the rendering). The trick I found out today is to place a solid white layer on top of your target and adjust the opacity of the white layer down to 80%. Gives better results. Also, of course, you need to start off with a downsized result (target needs to be at least 4 times smaller then final size in order to see a good grid pattern spacing; for this result, the size was 1/5 the final size). May try a tutorial later, but, as many here already know, I hate doing tuts. lol

OK.
When definitely ready for a detailed tutorial, I will try to implement your method in a filter (if you like so).

this is the outcome of my filter, Lyle.
I followed your tutorial except for:
- when downsizing applied exactly width/2 and height/2
- when using 3d elevation applied exactly width*2 and height*2
- white layer on top in SCREEN_MODE not applied (bad results for me)
- added a Stretch HSV before applying the final Contrast

If you like, I can post the filter here (when you will wake up again....)

Result looks pretty good, but, again, if you use a smaller image, you will get a wider grid. You could make the downsize amount an option (wouldn't go more than divide by 6). :)

do you prefer I change the filter or do you want to get it in the current version to test it?

Would be nice, Diego. I like the wider mesh grids. :)

just now I posted it in its current status (under the other topic).
Now I will update it and post the amended version for when you come back
