Hi,
I'm not sure I completely understand what you mean by "angle."
There is something called "angle" that actually controls the the type of
"lense" that you are using (i.e. a wide angle verses a telephoto). These
settings are independent.
The angle at which the camera is pointing is not controlled by an "angle"
setting. Instead, you give it the camera position, and then another point
that it should look at. The camera angle automatically adjusts to look at
that second "look_at" point.
Does that hellp?

| (...) Hi, I have just one quick question, does this work with all camera angles? i.e. if the angle parameter were set to 10 degrees? Thanks in advance Jay Jacinto (24 years ago, 30-Oct-00, to lugnet.cad.mlcad)
