Hi all... I'm trying to get my head round transforms, especially with
the camera. I've gone through the transforms chapter in Paul Catenese's
book a few times now and cant seem to get my head round it.

I basically want to do this...
At the start of the movie, set the camera up into a nice initial start
position for viewing the 3d object. I want to store this
position/transform of the camera so that I revert back to it when the
user clicks 'reset'.

I then want to allow the user to rotate the camera round the object and
zoom in and so on with mouse and keyboard inputs.

Does anyone know of any good examples I can rip through to help me get
my head round this once and for all?

The method im thinking of is that I need to set up a transform, eg.
myTrans = transform(), then edit this transform and set the camera to
it. I can then use scene.camera[1].transform.identity to reset it
right??

Anyway, I'd very much appreciate some help.

Thanks in advance
James.
