Set height of iterated objects based on curve height position

[xFlaye]

Hi,

I've created a basic picket fence setup. Each picket is positioned on a ground fence segment based on its width, as well as the segment's length.

 

There's a curve_height that I want each individual picket to extend to. I'm currently stuck as to which part of the for-loop to put it in.

The curve_height section is in the red network box.

Thanks for the help.

Hi,

the new nodes and nodes I've changed are green.

Thank you, @vicvvsh!

So that I'm clear on the process, you've created an attribute (pt_id) to every point on the ground curve and set the height value from the curve_height to each of those pt_id's. Then copied that to the scale parameter. Thus, every picket now will scale according to the value represented by the assigned point.

That's an elegant and efficient solution.

Much appreciated.

Yes, that's right. v@scale is non-uniform scale point attribute - https://www.sidefx.com/docs/houdini/copy/instanceattrs.html
