How do I: Many Bezier curves with POPs

[ButchBangher]

I can figure out how to make a short bezier curve with a single line POP, by manually placing all the points to be interpolated.

Now I want to do this en masse. Similar to a polyhop tutorial (https://youtu.be/6WuEprFA6TE) where just the start, middle, and end points are defined in a CHOP and used to make some SOPs.

But I can’t find a way to… Dynamically make line segments in bulk from a list of points? Or I can’t figure out how to group them accordingly and “copy pop” based on a bunch of starting points using bezier curves.

I can maybe do it with straight lines, but when I try the line smooth pop, sometimes I crash on windows.

Just wondering if anyone has some intermediate level resources for working with bezier curves and POPs, I’d love to study

Hello @ButchBangher
A similar question was posted on this forum some time ago.

RFE: Line POP. Pass points through a DAT

Hello there! I’m encountering that it would be really handy to be able to pass points for the Line POP via a DAT or a CHOP (and subsequently perhaps via an array through a python method) That seems particularly useful for something line Bezier curves, which sometimes have many points and are more easily created in a table than by filling dozens of values in the line Points tab. Best, Darien

Greg and I posted some examples showing how to use a combination of DAT to POPs, Primitive POP and Divide POP to create a Bezier curve from a DAT. Can it help?

For the crashes you are experiencing, a fix was recently added to the Line Smooth POP. It could be related to this problem.

Crash in Line Smooth and Line Divide

CrashAutoSave.Attractor.3.toe (2.6 MB) Connecting either will result in crash, In Line Divide, only Division Method param set to ‘Distance by Curvature’ In Line Smooth any value for Pre-Divide.

If not, please feel free to demonstrate how this can be reproduced.

Not only can it help, but its an exceptionally informative example that would go great in snippets if not already there. Thank you immensely, this is an awesome starting point!

Re: crash using Distance by Curvature, yes I believe this is exactly what I experienced as well. But I will probably wait until I understand better when/why to use Line Smooth/Divide POPs before using them again. Thanks for being aware of this issue.
