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
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.
