* @class vtkExtractCellsAlongPolyLine
|
|
* @brief Extracts input cells that are intersected by a list of input lines or poly lines
|
|
*
|
|
* This filter extracts input cells that are intersected by a list of input lines or poly lines.
|
|
* The lines / poly lines input is set on input port 1, as a source connection, while the input data
|
|
* set on which cells are extracted is to be set on input port 0. The produced output is a
|
|
* `vtkUnstructuredGrid`. Input lines can be either set inside a `vtkPolyData` or a
|
|
* `vtkUnstructuredGrid`. If the input type has an explicit geometry, i.e. the input is not a
|
|
* `vtkPointSet`, then the user can set the output
|
|
* points precision using `OutputPointsPrecisions`. Otherwise, the point precision is set to be the
|
|
* same as the input.
|
|
*
|
|
* This filter uses multi-threading if available.
