Abstract
An apparatus for displaying virtual objects within a physical set or scene. The apparatus includes a set assembly including at least one physical object, e.g., a background prop. A virtual object display assembly is provided with: a display element with a screen operable to display an image of an object; a beam splitter positioned at an angle between the screen and the set assembly; and a mask display element positioned within the set assembly at an image plane associated with the displayed image. The mask display element operates, when the display element operates to display the displayed image, to display a mask corresponding to the displayed image. The beam splitter is transmissive and reflective of light. The mask display element is positioned between the beam splitter and the physical object, and the displayed mask occludes a portion of the physical object and casts a shadow within the set assembly.
