APPARATUS AND METHOD OF USING ACCELERATION STRUCTURE IN RAY TRACING |
| 摘要 |
An apparatus and a method of using an acceleration structure in ray tracing, and a method of ray tracing are provided. The method involves setting a bit stack value of a level of an acceleration structure, moving to a child node among the ray-crossing child nodes and setting a route value of a corresponding level of the acceleration structure, and determining a pop level based on one or more bit stack values. |

1. A method of using an acceleration structure for ray tracing, the method comprising:
setting a bit stack value of a level of an acceleration structure based on a number of ray-crossing child nodes; moving to a child node among the ray-crossing child nodes and setting a route value of a corresponding level of the acceleration structure; and in response to the child node being a leaf node or a derivative node of the child node not intersecting a ray, determining a pop level based on one or more bit stack values. |
