#include <itkSpatialFunction.h>

Detailed Description

template<typename TOutput, unsigned int VImageDimension = 3, typename TInput = Point<double, VImageDimension>>
class itk::SpatialFunction< TOutput, VImageDimension, TInput >

N-dimensional spatial function class.

itk::SpatialFunction provides the ability to define functions that can be evaluated at an arbitrary point in space (physical or otherwise). The return type is specified by the derived class, and the input to the function is an n-dimensional itk::Point.

Although itk::ImageFunction and itk::SpatialFunction are quite similar, itk::SpatialFunction derived classes exist without reference to an Image type.

SpatialFunction is templated over output type (the data type returned by an evaluate() call) and dimensionality.
