[vtkusers] Writing a PVTP file

[Randall Hand]

I have a 50 million triangle PLY File written to disk that I would like to
convert to a Parallel VTP (PVTP) file for multithreaded rendering with
ParaView.  I tried simply connecting a vtkPLYReader to a
vtkXMLPPolyDataWriter, but it doesn't seem to have worked.  it's been
running for 45 minutes and I have a "city_0.vtp" going to disk, slowly.

Is this the correct method, or am I missing something?

=== Source
#include <stdio.h>
#include <vtkPLYReader.h>
#include <vtkXMLPPolyDataWriter.h>
int main (int argc, char *argv[]) {
    printf("Reading \"%s\"...\n", argv[1]);

    vtkPLYReader *reader = vtkPLYReader::New();
    reader->SetFileName(argv[1]);
    reader->Update();


    printf("Writing \"%s\"...\n", argv[2]);

    vtkXMLPPolyDataWriter *writer = vtkXMLPPolyDataWriter::New();
    writer->SetInput(reader->GetOutput());
    writer->SetFileName(argv[2]);
    writer->SetNumberOfPieces(24);
    writer->WriteSummaryFileOn();
    writer->Write();
}
====== End source
