I'm using PyQtGraph to plot mesh surfaces. I would like to see the 3D world with perspective turned off. 
Is this possible in pyQtGraph? I have searched through the documentation and the google groups and can't find any reference to this. I think it is possible in principle with openGL so is there a way to bring this out and control perspective on/off in pyQtGraph?
A cursory inspection of the docs renders no help ... however if you decrease the field of view (FOV) while also increasing the distance you will approximate an orthographic projection to arbitrary precision as you vary those two parameters
