I'm not sure this is an answer to your question, but have you looked at
scene.fov (field of view)?<br>

I've searched around and in the docs and haven't found an answer to
this.<br>
  <br>
I'm thinking of using Vpython to simulate models for 3d reconstruction
from 2d views. That is, I will create the 3d shape, and then take
several 2d images of it in order to test reconstruction algorithms. <br>
  <br>
To do this, I need to know the camera position and orientation, and its
focal length. The first two (position and orientation) are no problem.
I haven't seen anything on the third (focal length). I'm assuming that
the camera position is actually the focal point, so is there a way to
determine (or better, specify) the offset of the image plane from the
camera location (focal point)? <br>
  <br>
Thanks for any help,<br>
