Detailed Description

a nonlinear warp transformation

vtkGridTransform describes a nonlinear warp transformation as a set of displacement vectors sampled along a uniform 3D grid.

Warning: The inverse grid transform is calculated using an iterative method, and is several times more expensive than the forward transform.

virtual

virtual void vtkGridTransform::SetDisplacementGridConnection ( vtkAlgorithmOutput * )

virtual

Set/Get the grid transform (the grid transform must have three components for displacement in x, y, and z respectively). The vtkGridTransform class will never modify the data. Note that SetDisplacementGridData() does not setup a pipeline connection whereas SetDisplacementGridConnection does.

virtual void vtkGridTransform::SetDisplacementGridData ( vtkImageData * )

virtual

Set/Get the grid transform (the grid transform must have three components for displacement in x, y, and z respectively). The vtkGridTransform class will never modify the data. Note that SetDisplacementGridData() does not setup a pipeline connection whereas SetDisplacementGridConnection does.

virtual vtkImageData* vtkGridTransform::GetDisplacementGrid ( )

virtual

Set/Get the grid transform (the grid transform must have three components for displacement in x, y, and z respectively). The vtkGridTransform class will never modify the data. Note that SetDisplacementGridData() does not setup a pipeline connection whereas SetDisplacementGridConnection does.

virtual void vtkGridTransform::SetDisplacementScale ( double )

virtual

Set scale factor to be applied to the displacements. This is used primarily for grids which contain integer data types. Default: 1

virtual double vtkGridTransform::GetDisplacementScale ( )

virtual

Set scale factor to be applied to the displacements. This is used primarily for grids which contain integer data types. Default: 1

virtual void vtkGridTransform::SetDisplacementShift ( double )

virtual

Set a shift to be applied to the displacements. The shift is applied after the scale, i.e. x = scale*y + shift. Default: 0

virtual double vtkGridTransform::GetDisplacementShift ( )

virtual

Set a shift to be applied to the displacements. The shift is applied after the scale, i.e. x = scale*y + shift. Default: 0
