Usage
vtkGridTransform describes a nonlinear warp transformation
as a set of displacement vectors sampled along a uniform 3D
grid.
To create an instance of class vtkGridTransform, simply
invoke its constructor as follows
obj = vtkGridTransform
Methods
The class vtkGridTransform has several methods that can be
used. They are listed below. Note that the documentation is
translated automatically from the VTK sources, and may not
be completely intelligible. When in doubt, consult the VTK
website. In the methods listed below, obj is an instance of
the vtkGridTransform class.
* string = obj.GetClassName ()
* int = obj.IsA (string name)
* vtkGridTransform = obj.NewInstance ()
* vtkGridTransform = obj.SafeDownCast (vtkObject o)
* obj.SetDisplacementGrid (vtkImageData ) - 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.
* vtkImageData = obj.GetDisplacementGrid () - 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.
* obj.SetDisplacementScale (double ) - Set scale factor to
be applied to the displacements. This is used primarily
for grids which contain integer data types. Default: 1
* double = obj.GetDisplacementScale () - Set scale factor to
be applied to the displacements. This is used primarily
for grids which contain integer data types. Default: 1
* obj.SetDisplacementShift (double ) - Set a shift to be
applied to the displacements. The shift is applied after
the scale, i.e. x = scale*y + shift. Default: 0
* double = obj.GetDisplacementShift () - Set a shift to be
applied to the displacements. The shift is applied after
the scale, i.e. x = scale*y + shift. Default: 0
* obj.SetInterpolationMode (int mode) - Set interpolation
mode for sampling the grid. Higher-order interpolation
allows you to use a sparser grid. Default: Linear.
* int = obj.GetInterpolationMode () - Set interpolation mode
for sampling the grid. Higher-order interpolation allows
you to use a sparser grid. Default: Linear.
* obj.SetInterpolationModeToNearestNeighbor () - Set
interpolation mode for sampling the grid. Higher-order
interpolation allows you to use a sparser grid. Default:
Linear.
* obj.SetInterpolationModeToLinear () - Set interpolation
mode for sampling the grid. Higher-order interpolation
allows you to use a sparser grid. Default: Linear.
* obj.SetInterpolationModeToCubic () - Set interpolation
mode for sampling the grid. Higher-order interpolation
allows you to use a sparser grid. Default: Linear.
* string = obj.GetInterpolationModeAsString () - Set
interpolation mode for sampling the grid. Higher-order
interpolation allows you to use a sparser grid. Default:
Linear.
* vtkAbstractTransform = obj.MakeTransform () - Make another
transform of the same type.
* long = obj.GetMTime () - Get the MTime.
