Hello everybody, i found this tutorial, or breakdown, im starting and i didnt undestand how to start, he made a curve and then with point SOP and “sin and Cos function” he made the helix, but i dont understand where set the functions

In the webpage, it says “Point SOP”. This implies on the Position parameter of the Point SOP. http://www.sidefx.com/docs/houdini11.1/nodes/sop/point [sidefx.com]

I did that, but it doesnt work

It's something like this - see the scene. He first sets the red channel for the points to control the radius to something like (1-$BBY). Then there are two custom parameters “freq” & “amp” - see point2 SOP.

oohhh!!! I get it, thank you
