[vtk-developers] Failing test rendering problem

[Mathieu Westphal]

Hi

I have some problem with tests wich render and compare to an image.

Lots of test do the rendering which can be seen on screen, but the
generated image is completelly black ( or white ) and the test fail.

Most of these failing tests are python test but not only.
The list of failing tests is attached.

I've tried to understood what was going on, so i've tried to fix
sync3dAll.py

Adding :
        import time
        time.sleep(1)
        renWin.Render()
        time.sleep(1)

after the first render() did the trick. It look like the renderring is not
done fast enough ans the produced image is empty as it has not yet been
rendered.

Any help appreciated.
