Dear All,

 I've been experimenting a little bit with the camera position. I would
like to maintain my rendered
image orientation. For example, I want my x-axis(Red bar) positioned
horizontal z-axis(Green bar) vertical even if I change my camera
position while looking at the same position of the object.

One more question:
  What are the meanings of the non-zero values of y and z in "right
<0.35816, 0, 0.206784>".
I learned that x value of right< , , > maintains ratio of the image
output. But for the y and z, I have
hard time understanding.

Many thanks,

Jong
