No, actually I'm creating a scene that will be projected on a floor-to-ceiling screen in stereoscopic 3d with the idea that when you look at it, the projected image is an extension of the room you're standing in. So the camera position, angle, lens characteristics have to match the human eye, correct?

I really thought this would be somewhat easy - just slap a camera in the scene and place it roughly 6' off the ground and viola - but in reality it's not working out. When I use the grid lines as a guide, it looks like they diverge too sharply compared with the grid lines I painted on my floor.

I attached a sketch to illustrate the issue. Thanks for your time!
