This application discloses a ray interaction method, apparatus, device, medium, and product for virtual scenes. The method includes: receiving element configuration operations in the virtual scene; wherein the ray attributes include one or more of ray color and ray intensity; displaying a first incident ray received by a ray propagation element; and displaying a first outgoing ray emitted from the ray propagation element, wherein the first outgoing ray is a ray satisfying the first ray attribute obtained by adjusting a second ray attribute of the first incident ray. This allows ray propagation elements to be assigned ray attributes such as ray color and ray intensity, thereby allowing for richer adjustment of the incident ray received by the ray propagation element through the corresponding first ray attribute, to display a first outgoing ray satisfying the first ray attribute, enriching the ray interaction effects in the virtual scene. This application can be applied to various scenarios such as multiplayer battle games and virtual shooting scenarios.

Embodiments of this application relate to the field of electronic technologies. Provided are a rendering method and apparatus, a device, and a storage medium. In a graphics rendering process, for a to-be-rendered model included in to-be-rendered data, when the to-be-rendered model meets a first condition, ray tracing rendering is performed on the to-be-rendered model based on first ray emission density; or when the to-be-rendered model meets a second condition, ray tracing rendering is performed on the to-be-rendered model based on second ray emission density. When the first condition is different from the second condition, the first ray emission density is different from the second ray emission density. In the technical solution, when a condition met by the to-be-rendered model changes, ray emission density for performing ray tracing rendering can be adaptively adjusted, which reduces power consumption during rendering and improves rendering efficiency while ensuring a rendering effect.

A computer-implemented method of performing intersection testing in a ray tracing system. Intersection testing is performed for each of a plurality of rays against nodes of a hierarchical acceleration structure. Intersection testing for each of the rays comprises obtaining a first ray identifier associated with the ray S532. The first ray identifier is compared with a second ray identifier associated with a previously tested ray S508. Each ray identifier generalises ray data for its respective ray. In response to determining that the first ray identifier is equal to the second ray identifier, an indication of a re-entry point associated with the previously tested ray is obtained S512. Intersection testing of the ray against a set of nodes of the hierarchical acceleration structure is performed starting from the re-entry point S514. Also disclosed is computer readable code to perform the method, a ray tracing system and an integrated circuit to manufacture the ray tracking system.
