Detailed Description

extract parts of tensor and create a scalar, vector, normal, or texture coordinates.

vtkExtractTensorComponents is a filter that extracts components of a tensor to create a scalar, vector, normal, or texture coords. For example, if the tensor contains components of stress, then you could extract the normal stress in the x-direction as a scalar (i.e., tensor component (0,0).

To use this filter, you must set some boolean flags to control which data is extracted from the tensors, and whether you want to pass the tensor data through to the output. Also, you must specify the tensor component(s) for each type of data you want to extract. The tensor component(s) is(are) specified using matrix notation into a 3x3 matrix. That is, use the (row,column) address to specify a particular tensor component; and if the data you are extracting requires more than one component, use a list of addresses. (Note that the addresses are 0-offset -> (0,0) specifies upper left corner of the tensor.)

There are two optional methods to extract scalar data. You can extract the determinant of the tensor, or you can extract the effective stress of the tensor. These require that the ivar ExtractScalars is on, and the appropriate scalar extraction mode is set.

Member Function Documentation

virtual const char* vtkExtractTensorComponents::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 vtkDataSetToDataSetFilter.

virtual int vtkExtractTensorComponents::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 vtkDataSetToDataSetFilter.

int vtkExtractTensorComponents::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 vtkDataSetToDataSetFilter.

vtkExtractTensorComponents* vtkExtractTensorComponents::New   [static]
 

Construct object to extract nothing and to not pass tensor data through the pipeline.

Reimplemented from vtkDataSetSource.

void vtkExtractTensorComponents::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 vtkSource.

vtkExtractTensorComponents* vtkExtractTensorComponents::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 vtkDataSetToDataSetFilter.

virtual void vtkExtractTensorComponents::SetExtractNormals int    [virtual]
 

Boolean controls whether normal data is extracted from tensor.

virtual void vtkExtractTensorComponents::SetExtractScalars int    [virtual]
 

Boolean controls whether scalar data is extracted from tensor.

virtual void vtkExtractTensorComponents::SetExtractTCoords int    [virtual]
 

Boolean controls whether texture coordinates are extracted from tensor.

virtual void vtkExtractTensorComponents::SetExtractVectors int    [virtual]
 

Boolean controls whether vector data is extracted from tensor.

virtual void vtkExtractTensorComponents::SetNormalComponents int   ,
int   ,
int   ,
int   ,
int   ,
int   
[virtual]
 

Specify the ((row,column)0,(row,column)1,(row,column)2) tensor components to extract as a vector.

virtual void vtkExtractTensorComponents::SetNormalizeNormals int    [virtual]
 

Boolean controls whether normal vector is converted to unit normal after extraction.

Boolean controls whether tensor data is passed through to output.

virtual void vtkExtractTensorComponents::SetScalarComponents int   ,
int   
[virtual]
 

Specify the (row,column) tensor component to extract as a scalar.

virtual void vtkExtractTensorComponents::SetScalarMode int    [virtual]
 

Specify how to extract the scalar. You can extract it as one of the components of the tensor, as effective stress, or as the determinant of the tensor. If you extract a component make sure that you set the ScalarComponents ivar.

int   ,
int   ,
int   ,
int   
[virtual]
 

Specify the ((row,column)0,(row,column)1,(row,column)2) tensor components to extract as a vector. Up to NumberOfTCoords components are extracted.
