Patent ID: 10282894

Abstract:
According to one embodiment, a method includes identifying a scene to be rendered, pre-computing one or more lighting elements within the scene, including creating a plurality of light scattering tables, performing, during the pre-computing, a computation of light extinction and light in-scattering within participating media of the scene, utilizing the plurality of light scattering tables, and during a ray tracing of the scene, determining a homogeneous scattering coefficient for spatially homogeneous media of the scene, and applying to the spatially homogeneous media of the scene one of the plurality of light scattering tables, where each of the plurality of light scattering tables corresponds to a single homogeneous scattering coefficient, and a table lookup is adjusted for the one of the plurality of light scattering tables utilizing an analytic correction factor in order to apply the one of the plurality of light scattering tables with a different homogeneous scattering coefficient.
