Hi Gavin â€“ Thatâ€™s exactly what I have been working on for almost two years..
To achieve a true 3D walk-through you need to use programming to create a 3D environment or use 3D software like Maya, Max or Lightwave. The camera is placed on a path, but even that has limitation, so not really worth the effort..
I am now working on Flash Interactive 3D, but that has issues since the swf format is not compatible with iPads.. This is a great example of what I would like to achieve but its an entirely programmed 3D Virtual Tourâ€¦ It lacks a sense of realism.. http://gallery.3dcity.de/frontend/
There are other ways to view 3D objects/products, like using 3D interactive models in a pdf. But the most exciting 3D development would be webGL. This offers amazing opportunities to include all kinds of things into a Virtual Tour, but its very early days and webGL has issues of its own.
