This is a United States patent for inventions covering the rendering of virtual objects in an augmented reality environment.
Lighting provides one of the most important visual cues for tying the virtual world with the real one. This research describes
methods for measuring the real lighting environment and using it to render virtual objects.
(Abstract) A method and apparatus for rendering the lighting of virtual objects in an augmented reality display. The method
includes determining local and ambient light sources based on data provided by one or more light sensors. The light in the
physical lighting environment is accounted for by attributing the light to local light sources and/or ambient light sources.
A synthesized physical lighting environment is constructed based on the light characteristics of the local and/or ambient
light sources, and is used in properly rendering virtual objects in the augmented reality display.
