[vtkusers] vtkServerSocket, rendering and multithread

[uzay emir]

Hi All,



I want to receive data in one thread and render it in another, but
I have to make sure that the rendering thread starts rendering
only after the data has been received. I would like ask if Someone else tried these kind of things before?.


Any help would be appreciate

Uzay
