Is there any way, directly or indirectly, to get the data for camera location,
look_at, right, up, direction, angle, etc?

Any other "hidden" or system values that folks have found out how to get the
values for?

Thanks!

For the camera, the only way I know of is to use user defined variables 
to set the various parameters. You can then use those for any other 
purpose you need.

You also can use the default values. Those are documented.

There are some predefined constants. The most usefull ones, like pi, are 
documented. There are also some internal variables.

ALL predefined constants and internal variables are always in all lower 
case.
