/**
 * @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.
