Hello, as the tile says I’m looking for a curve3D function which, given a 3D points belonging to the curve, returns the tangent vector of the curve at this point. Ideally, this would be a unit vector.
Do you know if a function like this is available? I looked in the docs but didn’t find something usefull. I don’t really understand the definition of the up vectors…
If I don’t find solution, I plan to make a vector with an another point close to the first one, but it is not perfect…
Thanks for your answers, I’ll appreciate all of them !
See you ! Simon
