Re: [Visualpython-users] Simple question before diving into JPython.

I should have said: You can execute statements to position the camera in a
VPython program and not rely on manual zoom and rotate, if that is
important to you. Also, note that you can write an animation in VPython and
generate a series of POVRAY scene-description files to process.
