#include <itkRayCastInterpolateImageFunction.h>

Detailed Description

template<typename TInputImage, typename TCoordRep = double>
class itk::RayCastInterpolateImageFunction< TInputImage, TCoordRep >

Projective interpolation of an image at specified positions.

RayCastInterpolateImageFunction casts rays through a 3-dimensional image and uses bilinear interpolation to integrate each plane of voxels traversed.

Warning
This interpolator works for 3-dimensional images only.
Examples

◆ Evaluate()

template<typename TInputImage , typename TCoordRep = double>
OutputType itk::RayCastInterpolateImageFunction< TInputImage, TCoordRep >::Evaluate ( const PointType &  point) const
overridevirtual

Interpolate the image at a point position.

Returns the interpolated image intensity at a specified point position. No bounds checking is done. The point is assume to lie within the image buffer.

ImageFunction::IsInsideBuffer() can be used to check bounds before calling the method.

Reimplemented from itk::InterpolateImageFunction< TInputImage, TCoordRep >.

◆ EvaluateAtContinuousIndex()

template<typename TInputImage , typename TCoordRep = double>
OutputType itk::RayCastInterpolateImageFunction< TInputImage, TCoordRep >::EvaluateAtContinuousIndex ( const ContinuousIndexType &  index) const
overridevirtual

Interpolate the image at a continuous index position

Returns the interpolated image intensity at a specified index position. No bounds checking is done. The point is assume to lie within the image buffer.

Subclasses must override this method.

ImageFunction::IsInsideBuffer() can be used to check bounds before calling the method.
