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.
