random gradient

I have a surface that ive divided into 12 parts horz and vert. what im trying to do is cull out a random gradient of the panels.

so the top would keep 90% of them and then the bottom would only keep 10% of them

Like this? (test surface is - hopefully - internalized)

yeah except that is too sequential. how would you randomize it so the pattern appears more like a random bar graph instead of a set of stairs. I almost have it figured out i think. just needs some tweaking to get it to do what i want. thanks

All what you need is the rollTheBones and loadedDice booleans.

chaos is good, order is bad.

Oops forgot the casablanca int slider. Add some and re-roll the bones.

Hello Josh, guys,

If you want to control culling with percentages* you can do something like this:

*Of course with rounding up, as you cannot remove exactly 10% of 12 objects (without slicing them).

Hello Josh,

If you want to have the culled squares as well as the remaining ones you will need to replace [RandomReduce] with [SplitList] but then you must first shuffle each branch with [Jitter] so that you have a random pattern:

btw

@David Rutten: Couldn't [RandomReduce] component output the culled items as well? The space for an extra output exists (3 inputs->1 output) and hopefully this wouldn't be much work for you. It could be renamed to [RandomSplit] or something, to be more self-explanatory.

Hi Nikos, I agree it makes much more sense for components like Random Reduce, Cull, etc. etc. to insert nulls into the data rather than to shuffle data around. Makes it a lot easier to keep data lined up between distant regions of the file. A lot of components need to be rethought and made to work more consistent, but I don't think it will happen for Grasshopper1.
