// .NAME vtkDistributedStreamTracer - Distributed streamline generator
|
|
// .SECTION Description
|
|
// This filter integrates streamlines on a distributed dataset. It is
|
|
// essentially a serial algorithm: only one process is active at one
|
|
// time and it is not more efficient than a single process integration.
|
|
// It is useful when the data is too large to be on one process and
|
|
// has to be kept distributed.
