Detailed Description
template<class T>
class T2DConvoluteInterpolator< T >
The base class for 2D interpolators that use some kind of spacial convolution.
- Template Parameters
-
T data type to be interpolated
This class provides the interface for 2D interpolation based on some kind of spacial convolution, like e.g. by using B-splines.

helper class for the coefficient field
Definition at line 166 of file 2d/interpolator.hh.
| typedef T2DDatafield< typename coeff_map< T >::coeff_type > T2DConvoluteInterpolator< T >::TCoeff2D |
Data type of the field that holds the cofficients. Essentially, it uses the coeff_map template to translate whatever T is composed of to something that is composed of double float values to provide the required accuracy for interpolation.

Constructor & Destructor Documentation
| T2DConvoluteInterpolator< T >::T2DConvoluteInterpolator | ( | const T2DDatafield< T > & | data, |
| PSplineKernel | kernel | ||
| ) |
Constructor for the interpolator. The input data is pre-filtered in order to ensure that the interpolation at grid points returns the original data values.
- Parameters
-
data input data to base th einterpolation on kernel the B-spline kernel to be used.

| PSplineKernel | kernel, | ||
| const CSplineBoundaryCondition & | xbc, | ||
| const CSplineBoundaryCondition & | ybc | ||
| ) |
Construtor to prefilter the input for proper interpolation
- Parameters
-
data the data used for interpolation kernel the spline kernel used for interpolation xbc boundary conditions to be applied along the x-axis when interpolating ybc boundary conditions to be applied along the y-axis when interpolating
