Does it have to be Python? Our lab has developed a 3D mesh processing tool / framework called OpenFlipper: http://www.openflipper.org/ It is based on C++ and Qt. You can easily write new plugins to do arbitrary stuff, using C++. Scripting is done via Qt's JavaScript implementation. Would be nice to have Python bindings, though... :) > Currently, I've got some very coarse understanding of OpenGL and scenegraphs, > but cannot really grasp the complexitiy of the topic. This /can/ become arbitrarily complex, but you can start out simple. Getting efficient might be a problem. > Can anyone comment on the complexity of building it from scratch?

I wrote a minimal 3D viewer using both: https://github.com/root42/PyGLWidget It gives you a PyQt based window and a PyOpenGL context. Zoom, translate and rotate via mouse are already implemented. Nothing more, nothing less. I use the widget for small programs where I want to render some simple stuff. Best regards, Arne -- Dipl.-Inform.
