Quadratic Spline Interpolation Example | Numerical Methods

[@scottk3292]

Having worked in various 3d NURBS design software packages (as an end user, not as a programmer) it's driving me nuts to see that first section with zero curvature. I think about how the "curvature combs" would look in a program like Alias Studio. I originally wrote, asking you how this scales to cubic interpolation, and if cubic would be sufficient to achieve curvature continuity, but then after posting my question KZbin suggested your video on exactly that topic. For a non-mathematician who loves to mess around with this stuff, your videos are fantastic! Many thanks for your work here.

3:43 why is P1(x) expressed as a1x^2 + b1x^2 + c1? Shouldn't b1 only have x instead of x^2? This is only done for P1 P2, P3 are both written in the form of ax^2+bx+c

I'm going to assume this must be a typo, since the equations are written correctly at 2:00 But this leads to wildly different results so hopefully somebody else can correct me if needed

It seems the author corrects himself at 3:52

thank you for the series on interplation, possibly the clearest explanation out there :) however the link for "Quadratic spline interpolation theory" in the description is wrong, it redirects to linear spline interpolation video instead

Hello! I really appreciate how transparent and clear your notes are. What do you use to create them?
