Hello,<br><br>It works for me using the nightly VTK build, but it should be ok in 5.8/5.10. My python script calls (roughly) the following:<br><br>[All connections set up, Offscreen Rendering activated, camera properly positioned, there was an issue that the camera was aligned differently when doing offscreen rendering]<br>
window.Render()<br>window2image.Modified()<br>jpeg_writer.Write()<br><br>window is a vtkXOpenGLRenderWindow and I use a vtkOpenGLRenderer, I sit on a Debian System with proprietary nVidia drivers (304.48) and a GT 520.<br>
NB: I rendered a lot of images using this script, and with vtk 5.8 this caused the X-process to hog/leak memory. This was not the case using VTK6.<br><br>I do not know my way around QT & VTK together, but maybe this helps.<br>
<br>Best regards,<br>Johannes Strecha.<br><div class="gmail_extra"><br><br><div class="gmail_quote">On Tue, Nov 27, 2012 at 1:57 AM, Darshan Pai <span dir="ltr"><<a href="mailto:darshanpai@gmail.com" target="_blank">darshanpai@gmail.com</a>></span> wrote:<br>
