You should set VTK_USE_OFFSCREEN to on (I'm assuming you've already turned on VTK_OPENGL_HAS_OSMESA). Then you'll need to set the OSMesa libraries and header files (OSMESA_INCLUDE_DIR and OSMESA_LIBRARY). When I've done this in the past I didn't set VTK_USE_DISPLAY so you can probably leave that as is. To be safe, you may want to set OPENGL_INCLUDE_DIR, OPENGL_gl_LIBRARY, and OPENGL_glu_LIBRARY to the OSMesa versions of those (I'm not sure if this is necessary or not). Finally, then you'll need the following in your python script to turn on off screen rendering:<br>

From the discussion below I understand that setting up offscreen rendering properly is done at compile time:<br>

I have been looking at the Makefiles and config files in the 3.8.1 version, but there are so many of them...Should this be done in <a href="http://vtkPVConfig.h.in" target="_blank">vtkPVConfig.h.in</a> perhaps?
