template<int order, typename Kernel >

void Utils::Interpolation::bspline_3d	(	Vector3d const &	pos,
		Kernel const &	kernel,
		Vector3d const &	grid_spacing,
		Vector3d const &	offset
	)

cardinal B-spline interpolation with internal iteration.

Template Parameters

order	The number of interpolation points in each direction.
Kernel	Callable that can be called at every point with the index of the point and its weight as arguments.

Parameters

pos	The point at which the interpolation should be run.
kernel	Function to run for every point.
grid_spacing	The distance between the grid points.
offset	Shift of the grid relative to the origin.
