Even point distribution on a curve

[Tokezo]

Hi!
Is there a way to evenly distribute points on a curve? This curve for example. Resample doesn't give needed results

It's very easy. First compute the best fit plane of these points. You can use this VEX tool:

Then create a circle in VEX that's at origin on XZ plane, then using:

matrix3 m = dihedral ( {0,1,0}, bestFitPlaneNormal );

multiply your new circle points with m and then add bestFitPlaneCenter to these points.

Thank you, pusat! But what if i will have not an elliptic closed curve, what will be the solution then?

pusat's is by far the best way of doing this.

But for something rough and ready (and if you're not so bothered by being exactly even spaced) you could try this as well. Increasing the iterations on the for loop increases the 'accuracy'. It's based on even lengths of the original curve so is never going to be absolutely correct.

That's almost what i need, but it didn't work with my curve. Actually i'm getting this curve from edge group by converting it with python node. Maybe it's because python code generating some damaged curve?

Maybe you could give a hip file? Tried to recreate it, but realized that my skill is not enough for that

I've tried to fix your incoming curve. This seems to work..

My tree relies on the curve having sequentially numbered points so I merged your 3 primitives into 1 using polypath and then reordered the points using a UV attribute..

WOW! That's it! Now it's perfect, thank you very much!
