Derivative values for given (x0, y0) on the curve

[Ekrem Ekici]

Dear Members,

I am working on degree 3 BSpline to obtain combustor geometry for my research. My research requires to evaluate knot value for given point on curve. And also I should be able to calculate first and second derivative value for given point (x0, y0) of the curve.

Is there any special utility to perform these calculations?

Thanks for your interest.

Best wishes,

Ekrem

Ekrem,

I think you can try this solution for finding knot value from the curve points: https://groups.google.com/g/nurbs-python/c/Pm8CdXBk5wQ/m/Wgn176-VDAAJ

You'll probably need to modify it a bit to make it work for your case.

Thanks,

Onur
