What is a 3d film?
A 3d film is a film made with cameras that have no lens. I was thinking earlier about 3D models from sketchup and photographs. Do the 3d models really have depth, or are they not as flat as a photograph excepting that we can turn them? Last night I was watching the road and all the cars on it, when a bus stopped to let a car pull out. I was close to the left side of the bus with the car ahead going to the right, when it occured to me that this gap between them was so small from my perspective that it would be like a layer in sketchup. A layer with a car on it would pass between them, but in real life another vehicle wouldn't.
