* @class vtkAssignAttribute
|
|
* @brief Labels/marks a field as an attribute
|
|
*
|
|
* vtkAssignAttribute is used to label/mark a field (vtkDataArray) as an attribute.
|
|
* A field name or an attribute to labeled can be specified. For example:
|
|
* @verbatim
|
|
* aa->Assign("foo", vtkDataSetAttributes::SCALARS,
|
|
* vtkAssignAttribute::POINT_DATA);
|
|
* @endverbatim
|
|
* tells vtkAssignAttribute to make the array in the point data called
|
|
* "foo" the active scalars. On the other hand,
|
|
* @verbatim
|
|
* aa->Assign(vtkDataSetAttributes::VECTORS, vtkDataSetAttributes::SCALARS,
|
|
* vtkAssignAttribute::POINT_DATA);
|
|
* @endverbatim
|
|
* tells vtkAssignAttribute to make the active vectors also the active
|
|
* scalars. The same can be done more easily from Tcl by using the Assign()
|
|
* method which takes strings:
|
|
* @verbatim
|
|
* aa Assign "foo" SCALARS POINT_DATA
|
|
* or
|
|
* aa Assign SCALARS VECTORS POINT_DATA
|
|
*
|
|
* AttributeTypes: SCALARS, VECTORS, NORMALS, TCOORDS, TENSORS
|
|
* Attribute locations: POINT_DATA, CELL_DATA
|
|
* @endverbatim
|
|
*
|
|
* @warning
|
|
* When using Tcl, Java, Python or Visual Basic bindings, the array name
|
|
* can not be one of the AttributeTypes when calling Assign() which takes
|
|
* strings as arguments. The Tcl (Java etc.) command will
|
|
* always assume the string corresponds to an attribute type when
|
|
* the argument is one of the AttributeTypes. In this situation,
|
|
* use the Assign() which takes enums.
