RENDERING USING SHADOW INFORMATION

Abstract:

For a scene comprising real-world objects and generated (CG) objects, the scene characterized by a scene geometry of a first time, one or more processors can generate, based on the scene geometry, shadow information for each of one or more shadows cast by a CG object of the scene on one or more real-world objects of the scene. The one or more processors can rendering and display a frame of the scene as a function of the shadow information and a scene geometry at a time of the rendering later than the first time. In some examples, the shadow information includes shadow factors and identifiers. Each shadow factor can describe a light attenuation effect of a cast shadow on a real world object surface and can be incorporated into a shading atlas of the scene. Each identifier identifies a real-world object surface of the scene affected by a shadow factor.
