Abstract: Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing at least one program, and a method for rendering three-dimensional virtual objects within real world environments. Virtual rendering of a three-dimensional virtual object can be altered appropriately as a user moves around the object in the real world, and the three-dimensional virtual object can exist similarly for multiple users. Virtual object rendering can be with respect to a reference surface, like e.g. a floor or ground or table, in a real world environment, which reference surface can be selected by a user as part of the virtual object rendering process or by image processing methods.
