I've got 3 points in 3D space that I want to fit a curve to. I can figure out the math in 2D space but not in 3D space. I've searched for 3D, points, plotting but haven't been very successful. I'm basically looking for the math around the problem so I can work out the points along the path. I'm not interested in plotting it: just in working out the points.
What keywords should I be googling for?
