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

static 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.

static int vtkTensor::IsTypeOf ( const char *  name)
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 vtkObject.

virtual int vtkTensor::IsA ( const char *  name)
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 vtkObject.

static 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 82 of file vtkTensor.h.

double vtkTensor::GetComponent ( int  i,
int  j 
)
inline

Get the tensor component (i,j).

Definition at line 44 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 48 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 53 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 59 of file vtkTensor.h.

void vtkTensor::DeepCopy ( vtkTensor t)
inline

Deep copy of one tensor to another tensor.

Definition at line 94 of file vtkTensor.h.

vtkTensor::operator double * ( )
inline

Provide double * type conversion.

Definition at line 66 of file vtkTensor.h.
