 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.
