Detailed Description

supporting class to enable assignment and referencing of tensors

Date

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

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 *  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.

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

Reimplemented from vtkObject.

void vtkTensor::Initialize  )  [inline]
 

Initialize tensor components to 0.0.

Definition at line 84 of file vtkTensor.h.

References T.

float vtkTensor::GetComponent int  i,
int  j
[inline]
 

Get the tensor component (i,j).

Definition at line 47 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 51 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 56 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 62 of file vtkTensor.h.

void vtkTensor::DeepCopy vtkTensor t  )  [inline]
 

Deep copy of one tensor to another tensor.

Definition at line 95 of file vtkTensor.h.

References T.

vtkTensor::operator float *  )  [inline]
 

Provide float * type conversion.

Definition at line 69 of file vtkTensor.h.
