Detailed Description

a transform that doesn't do anything

Date:: 2002/01/22 15:25:27

Revision:: 1.25

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]

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 vtkTypeRevisionMacro 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 vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkLinearTransform.

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

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 ( vtkDataArray * inNms,

vtkDataArray * outNms

) [virtual]

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

void vtkIdentityTransform::TransformVectors ( vtkDataArray * inVrs,

vtkDataArray * 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,

vtkDataArray * inNms,

vtkDataArray * outNms,

vtkDataArray * inVrs,

vtkDataArray * outVrs

) [virtual]

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

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

Invert the transformation.
Implements vtkAbstractTransform.
Definition at line 81 of file vtkIdentityTransform.h.

Reimplemented from vtkLinearTransform.

void vtkIdentityTransform::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.
Reimplemented from vtkLinearTransform.

Reimplemented from vtkLinearTransform.

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

double out[3]

) [virtual]

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

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

vtkAbstractTransform* vtkIdentityTransform::MakeTransform ( ) [virtual]

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

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

Perform any subclass-specific DeepCopy.
Reimplemented from vtkHomogeneousTransform.
