Detailed Description

supporting class to enable assignment and referencing of tensors.

Date:

2001/10/11 13:36:26

Revision:

1.35

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]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. 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 vtkTypeMacro 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 vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkObject.

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

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkObject.

void vtkTensor::Initialize (    )  [inline]

Initialize tensor components to 0.0. Definition at line 108 of file vtkTensor.h.

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

Get the tensor component (i,j). Definition at line 71 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 75 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 80 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 86 of file vtkTensor.h.

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

Deep copy of one tensor to another tensor. Definition at line 119 of file vtkTensor.h.

vtkTensor::operator float * (    )  [inline]

Provide float * type conversion. Definition at line 93 of file vtkTensor.h.
