Member Function Documentation

virtual const char* vtkHomogeneousTransform::GetClassName (   )  [virtual]

Reimplemented from vtkAbstractTransform. Reimplemented in vtkIdentityTransform, vtkLinearTransform, vtkMatrixToHomogeneousTransform, vtkMatrixToLinearTransform, vtkPerspectiveTransform, vtkTransform, vtkIterativeClosestPointTransform, and vtkLandmarkTransform.

static int vtkHomogeneousTransform::IsTypeOf (  const char *  type  )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkAbstractTransform. Reimplemented in vtkIdentityTransform, vtkLinearTransform, vtkMatrixToHomogeneousTransform, vtkMatrixToLinearTransform, vtkPerspectiveTransform, vtkTransform, vtkIterativeClosestPointTransform, and vtkLandmarkTransform.

virtual int vtkHomogeneousTransform::IsA (  const char *  type  )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkAbstractTransform. Reimplemented in vtkIdentityTransform, vtkLinearTransform, vtkMatrixToHomogeneousTransform, vtkMatrixToLinearTransform, vtkPerspectiveTransform, vtkTransform, vtkIterativeClosestPointTransform, and vtkLandmarkTransform.

static vtkHomogeneousTransform* vtkHomogeneousTransform::SafeDownCast (  vtkObject *  o  )  [static]

Reimplemented from vtkAbstractTransform. Reimplemented in vtkIdentityTransform, vtkLinearTransform, vtkMatrixToHomogeneousTransform, vtkMatrixToLinearTransform, vtkPerspectiveTransform, vtkTransform, vtkIterativeClosestPointTransform, and vtkLandmarkTransform.

void vtkHomogeneousTransform::PrintSelf (  ostream &  os, vtkIndent  indent )  [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkAbstractTransform. Reimplemented in vtkIdentityTransform, vtkLinearTransform, vtkMatrixToHomogeneousTransform, vtkMatrixToLinearTransform, vtkPerspectiveTransform, vtkTransform, vtkIterativeClosestPointTransform, and vtkLandmarkTransform.

void vtkHomogeneousTransform::TransformPoints (  vtkPoints *  inPts, vtkPoints *  outPts )  [virtual]

Apply the transformation to a series of points, and append the results to outPts. Reimplemented from vtkAbstractTransform. Reimplemented in vtkIdentityTransform, and vtkLinearTransform.

virtual void vtkHomogeneousTransform::TransformPointsNormalsVectors (  vtkPoints *  inPts, vtkPoints *  outPts, vtkDataArray *  inNms, vtkDataArray *  outNms, vtkDataArray *  inVrs, vtkDataArray *  outVrs )  [virtual]

Apply the transformation to a combination of points, normals and vectors. Reimplemented from vtkAbstractTransform. Reimplemented in vtkIdentityTransform, and vtkLinearTransform.

void vtkHomogeneousTransform::GetMatrix (  vtkMatrix4x4 *  m  )

Get a copy of the internal transformation matrix. The transform is Updated first, to guarantee that the matrix is valid.

vtkMatrix4x4* vtkHomogeneousTransform::GetMatrix (   )  [inline]

Get a pointer to an internal vtkMatrix4x4 that represents the transformation. An Update() is called on the transform to ensure that the matrix is up-to-date when you get it. You should not store the matrix pointer anywhere because it might become stale. Definition at line 62 of file vtkHomogeneousTransform.h. References vtkAbstractTransform::Update(). Referenced by vtkTransform::MultiplyPoint().

vtkHomogeneousTransform* vtkHomogeneousTransform::GetHomogeneousInverse (   )  [inline]

Just like GetInverse(), but includes typecast to vtkHomogeneousTransform. Definition at line 67 of file vtkHomogeneousTransform.h. References vtkAbstractTransform::GetInverse().

void vtkHomogeneousTransform::InternalTransformPoint (  const float  in[3], float  out[3] )  [virtual]

This will calculate the transformation without calling Update. Meant for use only within other VTK classes. Implements vtkAbstractTransform. Reimplemented in vtkIdentityTransform, and vtkLinearTransform.

void vtkHomogeneousTransform::InternalTransformPoint (  const double  in[3], double  out[3] )  [virtual]

This will calculate the transformation without calling Update. Meant for use only within other VTK classes. Implements vtkAbstractTransform. Reimplemented in vtkIdentityTransform, and vtkLinearTransform.

void vtkHomogeneousTransform::InternalTransformDerivative (  const float  in[3], float  out[3], float  derivative[3][3] )  [virtual]

This will calculate the transformation as well as its derivative without calling Update. Meant for use only within other VTK classes. Implements vtkAbstractTransform. Reimplemented in vtkIdentityTransform, and vtkLinearTransform.

void vtkHomogeneousTransform::InternalTransformDerivative (  const double  in[3], double  out[3], double  derivative[3][3] )  [virtual]

This will calculate the transformation as well as its derivative without calling Update. Meant for use only within other VTK classes. Implements vtkAbstractTransform. Reimplemented in vtkIdentityTransform, and vtkLinearTransform.

void vtkHomogeneousTransform::InternalDeepCopy (  vtkAbstractTransform *  transform  )  [protected, virtual]

Perform any subclass-specific DeepCopy. Reimplemented from vtkAbstractTransform. Reimplemented in vtkIdentityTransform, vtkMatrixToHomogeneousTransform, vtkMatrixToLinearTransform, vtkPerspectiveTransform, vtkTransform, vtkIterativeClosestPointTransform, and vtkLandmarkTransform.
