Can anyone point me in the right direction… Id like to work out how to match cameras, distances and perspectives in papervision to other 3d media.

Lets say for example I take a photo of a table looking at it from an angle, I take it with a 35mm lens. If I take this into a 3d app (c4d for me) its fairly easy to create a camera which matches the one I took the photo with and then adjust the positioning so that I can use the photo as a background and when I add 3d assets they look just like they are inside the scene.

But how on earth do I do this in Papervision? Has anyone found a way of matching a 3D scene from a 3D app to one in papervision? so for example I can have interactive photos on my table image and they match the perspective of the real life camera positioning focal length… (ie. so it looks real basically)

I hope Ive explained this properly, anyone had to do this kind of thing before?  
thanks a million.
