Abstract
An interaction system is described which uses a depth camera to capture a depth image of a physical object placed on, or in vicinity to, an interactive surface. The interaction system also uses a video camera to capture a video image of the physical object. The interaction system can then generate a 3D virtual object based on the depth image and video image. The interaction system then uses a 3D projector to project the 3D virtual object back onto the interactive surface, e.g., in a mirrored relationship to the physical object. A user may then capture and manipulate the 3D virtual object in any manner. Further, the user may construct a composite model based on smaller component 3D virtual objects. The interaction system uses a projective texturing technique to present a realistic-looking 3D virtual object on a surface having any geometry.
