Random disribution in Y of multiple width elements (Array 2S)
« on: January 07, 2016, 04:04:40 PM »
I'd like to make parquet floor with these constraints :

Board length : between 3200 & 4200 mm (not a problem, 3200 mm  + random scale in Y between 100 & 135)

Board width : random between either 272 mm / 302 mm / 332 mm

The problem is that the randomize operator randomize "by element" thus randomizing in X & Y. But I want of course that all the elements with the same Y index have the same width...

I tried to modify the library parquet floor with no luck (even without doing the first X counter half length board) I'm sure the solution is really simple though ! (and pretty sure I've read somthing similar here but can't find the post either)



PS : To illustrate my need, The Vals Spa walls by Peter Zumthor are based on the same principle

Hi,

You should find the Random number parameter node will help you with this. It allows you to specify precisely when a random number is generated from either: at the start; for each segment; for each X Spline; for each X Spline section; or for each row on the Y axis. In this case it's the latter you want.

You could then wire this parameter to either the exported Fixed Size or Scale inputs of a Transform operator, or if you wish to use it to select segments you can use it wired to the Index of a Selector operator as shown below.



I hope that helps, please let me know if you need anything further.

Cheers!

Paul
