| Post subject: | Boundary conditions of spline2D |
Hi all, I'd like to use the spline2d-interpolation algorithm for a research project and wondered about the boundary conditions that are used by it. For the spline1d, I found that there are certain possibilities like natural and parabolically terminated ones. Can you tell me which of them are implemented for spline2d - or is it even possible to chose? |

By default, it uses parabolically terminated boundary conditions. These conditions are applied to 1-dimensional splines used to build 2-dimensional one. If you want, you can find BicubicCalcDerivatives() function, which prepares derivative information for 2-dimensional spline, and change it by changing boundary conditions passed to Spline1DBuildCubic(). |
