How would this be different from the existing Scene interpolation capability? 
You can use the Scene menu to Append a series of scenes of the molecule (views+representations) and then use Scene -> Next, PAGE-DN or  the scene command  to interpolate through them.

Subject: [PyMOL] real time first person camera view / control

hello -

i would like to create a first person view so that it is as if you are walking around the scene. would this be possible through pymol's python interface while maintaining adequate performance for real time interaction?

if not, would it be possible/difficult to alter the source code in such a way that the camera view control may be set up to mimic a first person view of the scene?
