I want to convert images / movies of real objects and scenes into virtual 3d objects. Any free or demo-able end user apps exist?

Linux or Windows.

As input it should take multiple images. Videos are simply a collection of multiple images even if I have to extract the images with a third utility. So images are a must and videos a plus.

The output should be a 3d model or scene in any commonly used 3d editor format.

For extra bonus points it should allow the scene to be non-static letting me watch my favorite movie from any angle even if, from the opposite view of the camera I only see untextured polygons.
