◆ bspline_3d()

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
orderThe number of interpolation points in each direction.
KernelCallable that can be called at every point with the index of the point and its weight as arguments.
Parameters
posThe point at which the interpolation should be run.
kernelFunction to run for every point.
grid_spacingThe distance between the grid points.
offsetShift of the grid relative to the origin.
