Hi!

I've got a simple curve with a bunch of points on it. I've generated a list of all the neighbour points and I grouped a few points on the line. I would like to grow this group by using the neighbours info and controlling the “spread” amount with a channel slider.

I've seen somebody use a solver to grow a group over time but I'd like a slider to do this.

Thanks for any help!

Group create / Disable Base Group / Group Type=Points / Include by edges / Edge Depth (your slider) , point group= initial points..

“edge depth”, nice little parameter I wasn't aware of! (-:

Thanks alecaile, it works nicely!

I'm still curious on how to do this in vex using the neighbours function and iteration channel slider. Anyone knows how to do this?

Use your slider to determine how many times to loop through the array.

I meant, I'd like to know how to replicate the same growth in VEX.

Yes…loop through the array you create with the neighbors function in vex.

Post your hip otherwise, maybe I am misunderstanding you.

That's the thing, I DON'T know how to do this in VEX and I'm looking for an example. I don't know how to “loop” through an array. I have zero clue! Any help is appreciated.

Ok…thought neighbors would list all the connected points of the same line ( in succession ).

Could still loop with the neihbors function as it works and just replace the reference point argument for each iteration.

But in this case since you have ordered point numbers you can do as in the hip file.
