Abstract
A ray tracing core comprises a ray tracing unit (RTU), a control unit, and a tree build unit (TBU). The ray tracing unit performs ray tracing based on a spatial partitioning structure. The control unit calculates the degree of complexity of the spatial partitioning structure by monitoring the load state of the ray tracing unit. The tree build unit builds the spatial partitioning structure having the degree of complexity which is calculated. The load state is determined based on a frame rate which is processed in the pertinent unit. The spatial partitioning structure applies a K-dimensional tree. For example, the degree of complexity can be modified according to either the maximum primitive number of a leaf node with respect to a K-dimensional tree structure or a tree depth.
