[vtkusers] writing time-dependent data

[Rustem Khabetdinov]

Hello,

I know it is late but this might help you. The way I do it using python:

import vtk
> data_to_write = vtk.vtkUnstructuredGrid()
> writer = vtk.vtkXMLUnstructuredGridWriter()
> number_of_steps = 5
> writer.SetNumberOfTimeSteps(number_of_steps)
> writer.SetInputData(data_to_write)
> writer.SetFileName('path/to/file')
> writer.Start()
> for i in range(number_of_steps):
>   data_to_write.ShallowCopy(some_input_data)
>   writer.WriteNextTime(i)
> writer.Stop()


Hope this helps anyone
