Variable sized Voronoi
« on: May 11, 2017, 12:02:45 PM »
One for the math heads ...
Any ideas how to get Variable sized Voronoi.
The Voronoi has a scale input that can have a constant scalar input (see attached). I need to figure out how to have a variable scalar input, say something between 1 and 3 (or stepped 1, 2 or 3). I have tried a PF but that creates a mess.
Suggestions .. :)

Did you try with color set at 3 and 1 and then a smallest fractal noise that is higher than that? I use variable size sometimes, and it does work.

Hmm, I hadn't thought of trying colour values above 1. Kinda works but not quite what I'm after ... might not be quite understanding you properly. I shall investigate further ..

hi cyphyr

definitely NOT a math head here...but maybe this is something in your direction. Hope it helps.
cheers, Klaus

Thinking outside the box, good solution. Again not what I had in mind but quite possibly more useful.
Cheers

What's the effect you're looking for?

This is another attempt at a "perfect cliff" face ... I think what I'm after is a mixture of larger and smaller scale voronoi but not overlapping. Duplicating the layers and running a second pass for finer details would be better than having all the complexity is a single layer ...

Ah, cliffs, the endless pursuit of perfection. You'd have to make each size mask out (or in) the smaller sized (mix color with controllers?). Curious to see your results!

Well I managed to get as far as this. Two scales in one Voronoi.

That is what I got.
Tried to do something with the min-max nodes.
There are a few roads to go from the intermediate steps I think.
Gotta get some sleep...cheers, Klaus

Those are both interesting results. Klaus' version looks like broken glass, very nice. Thanks for posting these, guys.

By reducing the (50) shades of grey, the boundaries of cells with near shades are breaked down.
