  • System and method for real-time ray tracing in a 3D environment
    Patent number: 12664719
    Abstract: For rendering a three-dimensional (3D) scene, a set of parameters for one or more objects in the 3D scene are identified. Intermediate structures and corresponding objects for each of the one or more objects in the 3D scene are determined based on the set of identified parameters. A hybrid acceleration structure is determined based on the determined intermediate structures and a classical acceleration structure. A color contribution is determined for the hybrid acceleration structure. The 3D scene is then rendered based on the determined color contribution of the hybrid acceleration structure.
    Type: Grant

  • System and method for real-time ray tracing in a 3D environment
    Patent number: 12322037
    Abstract: A method and a system for rendering a 3D scene are disclosed. A set of parameters for objects in the 3D scene are identified. The objects are grouped based on the identified set of parameters and spatial boundaries for an intermediate structure group of objects based on an object type is determined. An illumination contribution for each plane of the spatial boundary of the intermediate structure is determined for the objects in the 3D scene. The 3D scene is then rendered based on the determined spatial boundary and the illumination contribution of the intermediate structure for each object in the scene.
