Ray tracing method, ray tracing apparatus for performing same, and recording medium for storing same

The present invention relates to a ray tracing device comprising: a main ray tracing unit for generating an acceleration structure (AS), transmitting scene data, and performing ray tracing for a part of the scene data; and a plurality of sub ray tracing units serially connected to each other, each of remaining sub ray tracing units except for the last one among the sub ray tracing units relaying the scene data to a next sub ray tracing unit, and performing ray tracing for different parts of the scene data. Thus, the present invention has a plurality of chips for processing a ray tracing so that rendering for a three-dimensional image can be processed in real time.
