Using the max/min_extend functions seems to be the correct way to do it, 
I would then center it, and compute the camera position according to the 
size of the object, but I don't expect a lot of calculations for that. 
You should be able to set a correct position with a few test and tries.
You can also have a fixed camera and scale your objects to fit in a 
given box, for example box { -1, 1 }, you would have to find their 
biggest dimension and then scale that dimension to the box.

I hope that helps,
