Detailed Description

a transform that doesn't do anything.

Date:

2000/12/10 20:08:11

Revision:

1.14

Thanks:

Thanks to David G. Gobbi who developed this class.

vtkIdentityTransform is a transformation which will simply pass coordinate data unchanged. All other transform types can also do this, however, the vtkIdentityTransform does so with much greater efficiency.

Member Function Documentation

vtkIdentityTransform* vtkIdentityTransform::New (    )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on. Reimplemented from vtkObject.

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

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkLinearTransform.

int vtkIdentityTransform::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 vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkLinearTransform.

virtual int vtkIdentityTransform::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 vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkLinearTransform.

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

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkLinearTransform.

void vtkIdentityTransform::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 vtkLinearTransform.

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

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

void vtkIdentityTransform::TransformNormals (  vtkNormals *    inNms, vtkNormals *    outNms )  [virtual]

Apply the transformation to a series of normals, and append the results to outNms. Reimplemented from vtkLinearTransform.

void vtkIdentityTransform::TransformVectors (  vtkVectors *    inVrs, vtkVectors *    outVrs )  [virtual]

Apply the transformation to a series of vectors, and append the results to outVrs. Reimplemented from vtkLinearTransform.

void vtkIdentityTransform::TransformPointsNormalsVectors (  vtkPoints *    inPts, vtkPoints *    outPts, vtkNormals *    inNms, vtkNormals *    outNms, vtkVectors *    inVrs, vtkVectors *    outVrs )  [virtual]

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

void vtkIdentityTransform::Inverse (    )  [inline, virtual]

Invert the transformation. Reimplemented from vtkAbstractTransform. Definition at line 92 of file vtkIdentityTransform.h.

void vtkIdentityTransform::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. Reimplemented from vtkLinearTransform.

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

Reimplemented from vtkLinearTransform.

void vtkIdentityTransform::InternalTransformNormal (  const float    in[3], float    out[3] )  [virtual]

This will calculate the transformation without calling Update. Meant for use only within other VTK classes. Reimplemented from vtkLinearTransform.

void vtkIdentityTransform::InternalTransformNormal (  const double    in[3], double    out[3] )  [virtual]

Reimplemented from vtkLinearTransform.

void vtkIdentityTransform::InternalTransformVector (  const float    in[3], float    out[3] )  [virtual]

This will calculate the transformation without calling Update. Meant for use only within other VTK classes. Reimplemented from vtkLinearTransform.

void vtkIdentityTransform::InternalTransformVector (  const double    in[3], double    out[3] )  [virtual]

Reimplemented from vtkLinearTransform.

void vtkIdentityTransform::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. Reimplemented from vtkLinearTransform.

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

Reimplemented from vtkLinearTransform.

vtkAbstractTransform* vtkIdentityTransform::MakeTransform (    )  [virtual]

Make a transform of the same type. This will actually return the same transform. Reimplemented from vtkAbstractTransform.

void vtkIdentityTransform::operator= (  const vtkIdentityTransform &    )  [inline, protected]

Definition at line 124 of file vtkIdentityTransform.h.

void vtkIdentityTransform::InternalDeepCopy (  vtkAbstractTransform *    t )  [protected, virtual]

Perform any subclass-specific DeepCopy. Reimplemented from vtkHomogeneousTransform.
