I've had some other stuff going on lately. I'll get to this today - and get the judging spreadsheets sent to Dino as well.Yeah!

I'm excited to see what you'll do with this month's topic.A propos, HS - do you per chance know if there is in the equation editor any derivative/slope/normal function I can use? Not on coordinates, but on numbers.
Hmmm, that's a good question. Could you achieve the same effect with a mixed material using some kinda' cellular function, I wonder? Must admit, that's a tricky oneCSE wrote: ↑Thu Oct 05, 2017 12:52 pmA propos, HS - do you per chance know if there is in the equation editor any derivative/slope/normal function I can use?

Context: I use a noise node to get a pattern based on the location (x, y, z)->[0-1]. This pattern has distinct regions of the same value (imagine for example a political map: countries in one colour; one with 0.2, another with another colour 0.5 for example). I try to get the frontiers, so the locations where the value change (from 0.2 to 0.5 in our example) in order to make a line pattern (so from a (x, y, z), I get 1 if on the frontier, 0 if not). Could not find anything... it seems that as soon as the coordinates are transformed in a number, they loose the "view" of their neighbours.
Thanks for any hints...
This is a very good idea. Offset in one direction (x), then the other (y), substract both times with initial, take absolute value, add both, filter to a certain threshold... pity it's 1:30am and I just switched off my computer - need to try tomorrow!0111narwhalz wrote: ↑Thu Oct 05, 2017 4:44 pmHave you tried using some kind of offset? If you have (u,v) and measure points adjacent to it (like (u+d,v) and so on) you should be able to determine whether a given point is on an edge by comparing the values of those points. With smaller values of d you'll more closely approach a derivative, and your edge detection output will be stronger.
