// .NAME vtkPStreamTracer - Abstract superclass for parallel streamline generators
|
|
// .SECTION Description
|
|
// This class implements some necessary functionality used by distributed
|
|
// and parallel streamline generators. Note that all processes must have
|
|
// access to the WHOLE seed source, i.e. the source must be identical
|
|
// on all processes.
