|
* @class vtkTableToSparseArray
|
|
* @brief converts a vtkTable into a sparse array.
|
|
*
|
|
*
|
|
* Converts a vtkTable into a sparse array. Use AddCoordinateColumn() to
|
|
* designate one-to-many table columns that contain coordinates for each
|
|
* array value, and SetValueColumn() to designate the table column that
|
|
* contains array values.
|
|
*
|
|
* Thus, the number of dimensions in the output array will equal the number
|
|
* of calls to AddCoordinateColumn().
|
|
*
|
|
* The coordinate columns will also be used to populate dimension labels
|
|
* in the output array.
|
|
*
|
|
* By default, the extent of the output array will be set to the range
|
|
* [0, largest coordinate + 1) along each dimension. In some situations
|
|
* you may prefer to set the extents explicitly, using the
|
|
* SetOutputExtents() method. This is useful when the output array should
|
|
* be larger than its largest coordinates, or when working with partitioned
|
|
* data.
|
|
*
|
|
* @par Thanks:
|
|
* Developed by Timothy M. Shead (tshead@sandia.gov) at Sandia National Laboratories.
