Ray tracing apparatus and method

摘要

The ray tracing apparatus for three-dimensional (3D) graphics includes a Central Processing Unit (CPU) for constructing a first Acceleration Structure (AS) for a static object, and creating a second dynamic object by performing a Level Of Detail (LOD) operation on the first dynamic object and a ray tracing core for performing ray tracing based on the first AS and a second AS for the second dynamic object. The CPU or the ray tracing core constructs the second AS for the second dynamic object.

1. A ray tracing apparatus for three-dimensional (3D) graphics, comprising:
a Central Processing Unit (CPU) configured to construct a first Acceleration Structure for a static object, and to perform a Level of Detail (LOD) operation on a first dynamic object to create a second dynamic object, wherein the LOD operation is not configured to perform on the static object and the LOD operation is operated based on a distance between the first dynamic object and a viewer, wherein, in the LOD operation, when the first dynamic object moves away from the viewer, the CPU creates a coarse representation of the second dynamic object, and when the first dynamic object moves close to the viewer, the CPU creates a refined representation of the second dynamic object; and a ray tracing core being connected with the CPU through a bus interface and the ray tracing core being configured to construct a second Acceleration Structure for the second dynamic object created by the LOD operation, and to respectively perform ray tracing based on the first Acceleration Structure and the second Acceleration Structure for the second dynamic object to create an image for a current frame.
