Abstract: front page image
(EN)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 special 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. In one embodiment, the load state is determined based on a frame rate which is processed in the pertinent unit. In another embodiment, 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.
(FR)Un noyau de tracé de rayon comprend une unité de tracé de rayon (RTU), une unité de commande et une unité de construction d'arborescence (TBU). L'unité de tracé de rayon effectue un tracé de rayon sur la base d'une structure de division spéciale. L'unité de commande calcule le degré de complexité de la structure de division spatiale en surveillant l'état de charge de l'unité de tracé de rayon. L'unité de construction d'arborescence construit la structure de division spatiale ayant le degré de complexité qui est calculé. Dans un mode de réalisation, l'état de charge est déterminé sur la base d'une fréquence de trame qui est traitée dans l'unité pertinente. Dans un autre mode de réalisation, la structure de division spatiale applique une arborescence à K dimensions. Par exemple, le degré de complexité peut être modifié en fonction de l'un ou l'autre d'un nombre de primitives maximum d'un noeud terminal par rapport à une structure arborescente à K dimensions ou d'une profondeur d'arborescence.
(KO)레이 트레이싱 코어는 레이 트레이싱 유닛(Ray Tracing Unit, RTU), 컨트롤 유닛 및 트리 빌드 유닛(Tree Build Unit, TBU)을 포함한다. 상기 레이 트레이싱 유닛은 공간 분할 구조체(Spatial Partitioning Structure)를 기초로 레이 트레이싱(Ray Tracing)을 수행한다. 상기 컨트롤 유닛은 상기 레이 트레이싱 유닛의 부하 상태를 모니터링하여 공간 분할 구조체의 복잡도를 계산한다. 상기 트리 빌드 유닛 상기 계산된 복잡도를 가지는 공간 분할 구조체를 구축한다. 일 실시예에서, 상기 부하 상태는 해당 유닛에서 처리되는 프레임 비율(Frame Rate)을 기초로 결정될 수 있다. 다른 일 실시예에서, 상기 공간 분할 구조체는 KD 트리(K-Dimensional Tree)를 적용할 수 있다. 예를 들어, 상기 복잡도는 KD 트리 구조에 대한 리프노드(Leaf Node)의 최대 프리미티브 수(Maximum Primitive Number) 및/또는 트리 깊이(Tree Depth)에 따라 변경될 수 있다.
