HI Davi,
Sounds interesting, but I don't understand your terminology; 'the angle between points on a curve' sounds not uniquely defined (we're talking about a 1 dimensional object (curve) in (in this case) a 3 dimensional space...)
And what's more: what is a 'closed angle'???
And what does more spaced mean? Spaced further apart (as it sounds to me)?
I must admit: I haven't looked at the videos or the .blend file yet, just looked at the .png and I get a feeling for what I think you want to achieve, but it would help if you could be more precise.
Hello Martin, sorry for taking so long to answer, I wasn't notified of the reply.
Also the formatting got very messy on the actual post, sorry about that, no idea on why that is.
Either way, the angle between sections would make more sense, I suppose. I sample a point in the curve and calculate how obtuse/acute the angle at that point is.
If you take a look at the .blend file or the video it should become much clearer, in fact, I have generated a new .blend that's more organized and easier to understand:

It should be clean and organized enough, the part of the geo nodes modifier that's dealing with this function is the "DynDiv.002" group.
What I need, in short: Is a way to resample a curve, that I can adjust its parameters, such as:
- Minimum and maximum distance according to how accute the angle on my 3D curve is.
- How much that information affects the curve, making it have a lesser or greater effect on the output
- A input on how much points the curve will have in total (which is one of the reasons why the default resample node isn't useful to me)
If you open the .blend file and check it, I have pretty much all of that already working, EXCEPT for the fact that the final result has a bias whenever I move a handle towards either end of the curve or I rotate it around (changing the tangent of the handle) and I have no idea on why that is, as can be seen on this video:

The reason I am doing all this is to create a haircard tool which wouldn't require me to work on the topology by hand, makes it easy for me to setup LoDs and is reliable. If you check this other video of mine you can see a worse version of it in action, but it gives some context:

For now I don't need help with the other parts of the tool, I have most of it figured out, but this problem with the points moving towards one end or another is something I just couldn't work out. Thanks in advance.
