Detailed Description

supporting class to enable assignment and referencing of tensors

Date:: 2002/01/22 15:26:25

Revision:: 1.37

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::Initialize ( ) [inline]

Initialize tensor components to 0.0.
Definition at line 97 of file vtkTensor.h.
References T.

float vtkTensor::GetComponent ( int i,

int j

) [inline]

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

void vtkTensor::SetComponent ( int i,

int j,

float v

) [inline]

Set the value of the tensor component (i,j).
Definition at line 64 of file vtkTensor.h.

void vtkTensor::AddComponent ( int i,

int j,

float v

) [inline]

Add to the value of the tensor component at location (i,j).
Definition at line 69 of file vtkTensor.h.

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

Return column vector from tensor. (Assumes 2D matrix form and 0-offset.)
Definition at line 75 of file vtkTensor.h.

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

Deep copy of one tensor to another tensor.
Definition at line 108 of file vtkTensor.h.
References T.

vtkTensor::operator float * ( ) [inline]

Provide float * type conversion.
Definition at line 82 of file vtkTensor.h.
