Detailed Description

supporting class to enable assignment and referencing of tensors

vtkTensor is a floating point representation of an nxn tensor. vtkTensor provides methods for assignment and reference of tensor components. It does it in such a way as to minimize data copying.

Warning:: vtkTensor performs its operations using pointer reference. You are responsible for supplying data storage (if necessary) if local copies of data are being made.

Member Function Documentation

vtkTensor* vtkTensor::New ( ) [static]

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

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

Reimplemented from vtkObject.

int vtkTensor::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 vtkObject.

virtual int vtkTensor::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 vtkObject.

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

Reimplemented from vtkObject.

void vtkTensor::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 vtkObject.

void vtkTensor::Initialize ( ) [inline]

Initialize tensor components to 0.0.
Definition at line 94 of file vtkTensor.h.
References T.

double vtkTensor::GetComponent ( int i,

int j

) [inline]

Get the tensor component (i,j).
Definition at line 56 of file vtkTensor.h.

void vtkTensor::SetComponent ( int i,

int j,

double v

) [inline]

Set the value of the tensor component (i,j).
Definition at line 60 of file vtkTensor.h.

void vtkTensor::AddComponent ( int i,

int j,

double v

) [inline]

Add to the value of the tensor component at location (i,j).
Definition at line 65 of file vtkTensor.h.

double* vtkTensor::GetColumn ( int j ) [inline]

Return column vector from tensor. (Assumes 2D matrix form and 0-offset.)
Definition at line 71 of file vtkTensor.h.

void vtkTensor::DeepCopy ( vtkTensor * t ) [inline]

Deep copy of one tensor to another tensor.
Definition at line 106 of file vtkTensor.h.
References T.

vtkTensor::operator double * ( ) [inline]

Provide double * type conversion.
Definition at line 78 of file vtkTensor.h.
