Detailed Description

helper class to transform output of non-axis-aligned images

vtkImageTransform is a helper class to transform the output of image filters (i.e., filter that input vtkImageData) by applying the Index to Physical transformation frmo the input image, which can include origin, spacing, direction. The transformation process is threaded with vtkSMPTools for performance.

Typically in application the single method TransformPointSet() is invoked to transform the output of an image algorithm (assuming that the image's direction/orientation matrix is non-identity). Note that vtkPointSets encompass vtkPolyData as well as vtkUnstructuredGrids. In the future other output types may be added. Note that specific methods for transforming points, normals, and vectors is also provided by this class in case additional output data arrays need to be transformed (since TransformPointSet() only processes data arrays labeled as points, normals, and vectors).

Warning
This class has been threaded with vtkSMPTools. Using TBB or other non-sequential type (set in the CMake variable VTK_SMP_IMPLEMENTATION_TYPE) may improve performance significantly.

static void vtkImageTransform::TransformPointSet ( vtkImageData im,
vtkPointSet ps 
)
static

Given a vtkImageData (and hence its associated orientation matrix), and an instance of vtkPointSet, transform its points, as well as any normals and vectors, associated with the vtkPointSet.

This is a convenience function, internally it calls TranslatePoints(), TransformPoints(), TransformNormals(), and/or TransformVectors() as appropriate. Note that both the normals and vectors associated with the point and cell data are transformed.

static void vtkImageTransform::TranslatePoints ( double t,
vtkDataArray da 
)
static

Given x-y-z points represented by a vtkDataArray, translate the points using the image origin.

This method is useful if there is no orientation or spacing to apply.

static void vtkImageTransform::TransformPoints ( vtkMatrix4x4 m4,
vtkDataArray da 
)
static

Given x-y-z points represented by a vtkDataArray, transform the points using the matrix provided.

static void vtkImageTransform::TransformNormals ( vtkMatrix3x3 m3,
double  spacing[3],
vtkDataArray da 
)
static

Given three-component normals represented by a vtkDataArray, transform the normals using the matrix provided.

static void vtkImageTransform::TransformVectors ( vtkMatrix3x3 m3,
double  spacing[3],
vtkDataArray da 
)
static

Given three-component vectors represented by a vtkDataArray, transform the vectors using the matrix provided.
