[Paraview] Particle attributes in vtkPolyData

[Randy Hudson]

This code

    cout << "[VTKPolyDataSetup::CreateScalarArray_1Part] - 0 - varname:
    " << varname << endl;
    variable_color1->SetName(varname);
    cout << "[VTKPolyDataSetup::CreateScalarArray_1Part] - 0 -
    variable_color1->GetName(): " << variable_color1->GetName() << endl;

gives me

    [VTKPolyDataSetup::CreateScalarArray_1Part] - 0 - varname: p_dens
    [VTKPolyDataSetup::CreateScalarArray_1Part] - 0 -
    variable_color1->GetName(): ƒÄƒ‹ƒ´

almost ad infinitum.

Cf. the garbage at the end of the second line.

So, the name must not be being set.

"varname" is a char*, which, as you can see from the first line of 
output, contains a valid char string.

This should work, right?

"Just imagine if chutzpah destabilized the space-time continuum.  Then imagine Ted Kennedy taking to the floor of the Senate to denounce Cheney's accident reporting protocols.  Space and time would fold in on themselves in the well of the Senate and while Ted would vanish in a fzzztt...spork! and a burst of ozone, maybe a cool pterodactyl or woolly mammoth would escape through the rip in existence and terrorize the capitol.
