I learned in my lessons of math, that it is possible to interpolate 2D points to get a curve. I was a bit interessted in this concept, and wandered if you could extend it? Say you have some 3D points: a(x,y,z) b(x',y',z') c(x",y",z") ... Would it be possible to calculate a surface from this? To make my question clearer, here is a more concrete example: Suppose: a(1,0,0) b(0,1,0) c(0,0,1) d(-1,0,0) e(0,-1,0) f(0,0,-1) .... (all points lying on the surface of a sphere) Could I somehow deduce from this a curve with equation: x²+y²+z² = 1? Thanks for your help greatings GenZ
