3D Photo Editor can change objects in the photo

Imagine being able to manipulate objects in a digital image and expose areas that were never even captured in the original photograph. That’s precisely what a new open source editing tool is capable of doing. It allows for a full range of control – scaling, rotation, translation and deformation – in three dimensions. Models are used to complete the geometry and appearance, and reveal those parts that are hidden from view. The program also estimates the illumination, color and texture, while matching pixels to the original image to create a realistic representation of the object when it’s moved.

For example, the editing tool can be used to change the orientation of a chair in a still photo of a room, or to create an animation of a car flipping over from a single image.
