Wow, that's really garbled. It does not look like the problem I've seen before. > I haven't tried off screen rendering with the gui as I need to be able > to run the scripts in batch. > I just want to make sure you can make an output image at all. It does not have to be a useful rendering just take a screenshot of the sphere source. Then if that works and if you're doing volume rendering or something more advanced, then try to make the rendering closer, a little at a time, to what you are trying to do for real. The Paraview GUI switches to offscreen rendering to make an output image, but there is a check-box to turn that off and on. The problem I've seen where the output images were garbled ( not as badly as yours ) would happen whenever paraview or vtk took a screenshot. It did not matter if I used the GUI or not, offscreen or not, nor if there was a screen attached to the X server. > As a work around, I have output the openGL window to a secondary screen > (in a similar manner to that you described in a previous post yesterday) > which is working fine for my purposes. > > Lucy > So everything works as long as the rendering is displayed on an actual monitor?
