Hello,

Does anyone know if it is possible to do a cubic spline interpolation in a 3 dimension x,y,z plot? And how does one do it as i can't seems to find any example in doing a 3d. Thank you!

Edit: I do not understand the examples from the link:https://in.mathworks.com/help/curvefit/examples/constructing-spline-curves-in-2d-and-3d.html

Maybe anyone knows how to create more points using the cubic spline interpolation. For example a 3d size of 100x50x75 (x,y,z axis) into a 150x75x100. Thank you!
