[Visualpython-users] changing camera position

Hi,

I have spent the last couple days trying to get the following to work.
In Povray, we have a camera syntax like the following
camera {location <0,4,-6> look_at <0,1,3>}

The result is this

I have a hard time doing it in VPython.
I read the documentation, and had tried many combinations.

Can you guide me with more details on camera position?

Thanks.
