Well, sort of k-means (: The truth must be told: I don't know math much so I made it myself. No repeat nodes, just pure awesomeness of "build array from set" and "find in array" nodes.

You can disconnect polygon islands by k-means also (Disconnect Islands compound is attached below)



Compound is allow you to switch to any context

who's a clever lad eh!? so basically you made this?



awesome stuff. wouldn't know where to begin. thanks very much for posting, will have a look to see if I can understand the ICE tree flow later , thanks!

Nicely done, obviously.
But for the even more mathematically challenged like me,
could you perhaps say something more about the specific situations
where you would use this?

Yes, you can! Everyone can, I continue my K.I.S.S. workflow. And the most funniest part - that formula that you showed me - I don't understand it and I'm not used it. All stuff inside of compound is working on arrays sorting. And it works as if it was that formula! How can this be even possible?!


I don't know. But what I know for sure is that it was implemented in Houdini first, and I was thinking on that moment "I can do this in xsi too". He used for each (we call it repeat) node I guess (from description: "as the iterations go along"), I made it without any loops.

Nope.

I still have no idea what this is for.

I would like to know though.

Hi Sam, am fairly certain that this is related to breaking up objects into pieces where each piece is a voronoi cell http://en.wikipedia.org/wiki/Voronoi_cell - this you must have heard of / seen already

lol, guys

it's about the question... why we want to get an answer, if we don't need it

i mean what that sequence of numbers means... they're placed together for some reason, right? why you can find so many people who remembers them?

just watch it 'till the end

OK thanks for the help guys. I think I see what is being done here and I now know (sort of) what a Veroni Cell is.

Used by John Snow (no less) to help cure cholera. My favourite pub in Soho is named after him. I shall tell everyone about it when I'm in there next. Maybe I'll get a free drink (maybe not).

What use is this for computer graphics? Specifically Softimage users? Some kind of organic procedural modelling, shattering, noise?
Or something else?
