RENDERING SCENES USING A COMBINATION OF RAYTRACING AND RASTERIZATION

Abstract:

The disclosure is directed to methods and processes of rendering a complex scene using a combination of raytracing and rasterization. The methods and processes can be implemented in a video driver or software library. A developer of an application can provide information to an application programming interface (API) call as if a conventional raytrace API is being called. The method and processes can analyze the scene using a variety of parameters to determine a grouping of objects within the scene. The rasterization algorithm can use as input primitive cluster data retrieved from raytracing acceleration structures. Each group of objects can be rendered using its own balance of raytracing and rasterization to improve rendering performance while maintaining a visual quality target level.
