I forgot most of the details already but as far as I remember, some classes of splines are 4 dimensional constructs that are then projected to 3 dimension to get your 3d spline curve.
- Random_ernest 6y agoWhat you are referring to is used in e.g. CAD modelling, we call them non-uniform rational B-splines or NURBS. Recently there has been super interesting research on using these nurbs as ansatzfunctions e.g. for FEM stuff. They got a lot of applications.
