[vtkusers] offscreen rendering in threads

[Affolter Martin]

Hi everyone

I know that vtk is not thread safe, and that the rendering should be done in the main/UI -thread. Does this also apply to offscreen rendering, or is the following scenario possible?


1.       Create several threads in a console application.

2.       Each thread builds its separate vtk pipeline to render some data off screen.

3.       The content of the offscreen renderer is written to a rasterimage in the filesystem.

4.       The objects of the pipeline are destroyed, the thread terminates.

Any thoughts are welcome.
