Distance at Point along Curve

Hi there,
I've been struggling finding a way to get the actual distance at any given point along a curve.
My points are not equally distributed along the curve and the curve may be closed.
A little visualization:
I tried xyzdist() but that only gives me equally values across the curve.
My xyzdist() snippet:
vector primuv ;
float dist = xyzdist (3 , @P , 0 , primuv );
f@u = primuv .x ;
I would appreciate if someone gives me a hint how to solve this or a solution.
Kind regards,
Kilian

Thanks for the tip but I'm afraid I still get the equal values. Do I miss something? I also tried running a polypath before the resample.

Try a uvtexture sop in ‘arc length spline’ mode, set to run on points.

for polygonal curves you can also use Edge Transport SOP

mestela This works like a charm!
Thank you for your time!

The Distance Along Geometry SOP does exactly this.
