Abstract
A ray tracing core comprising a ray generation unit and a plurality of T&I (Traversal & Intersection) units with MIMD (Multiple Instruction stream Multiple Data stream) architecture is disclosed. The ray generation unit generates at least one eye ray based on an eye ray generation information. The eye ray generation information includes a screen coordinate value. Each of the plurality of T&I units receives the at least one eye ray and checks whether there exists a triangle intersected with the received at least one eye ray. The triangle configures a space.
