@metin Very cute Merin, I had to check the B part:

The B in splines means Basis, a mathematical term going way back to 19 th centuary.

The term B-Spline is newer and the definition is beyond my tiny mind:
"A B-spline is defined as a piecewise polynomial of order n {\displaystyle n}, meaning a degree of n βˆ’ 1 {\displaystyle n-1} "

From Wiki https://en.wikipedia.org/wiki/B-spline

@mbt3d Interesting! The NURBS Wiki page is also a nice read:

@metin I agree, there are some really clever people out there, thankfully πŸ˜€
