algorithmic modeling for Rhino

Searching for new surface division models

Hi everybody,

This is my first post and contribution to this community and i would like to share some of my observations and latest project progress. 

As for architect i was always fascinated how grasshopper can create a new, almost biological structures from single surface in rhino. Doing some research i concluded that in most cases it's a variation of vornoi algorithm. Although effects are stunning, they are very similar as vornoi is very hard to be controlled and get something not completely random.

And that's where i started my search for some new ways of surface divisions. Here i present you some of my progress in this matter:

Altough it still looks random, you can control it in some ways. Basic idea is that you take grid of points from surface, give everyone of them a weight value and create curve around that point, depending on whats relation between point weight and its neighbours weights. In this example it still looks completely random but only becouse weights values are completely random :p 

I will make update as soon i'll make some progress. Hope you like it, maybe it will inspire someone. Fell free to comment and ask questions.

It's used so often becouse it's an easy and fast way to get some effect, but i think its "abuse" for aesthetics goes back to dark ages of 3d graphics where it was used as one of main procedural textures.

well voronoi's real purpose is finding relationships with neighbors. But it is abused as an aesthetic.

Thanks for comments,
I'm aware how vornoi algorithm works, i've done some research and at some point i wasn't satisfied with the results. I know it can be very versatile, but for a lot of cases the work you must do on those points to get desired output is much greater than just create new algorithm. Kind regards

Voronoi does not have to be random. In fact it can be quite specific and easily controlled. What matters is your point locations and relations to each other.
