Abstract
A method of processing ray tracing comprising acquiring information about a light source and a bounding box that are located in a three-dimensional graphics (3D) graphics environment, the bounding box containing an object; testing whether a ray generated by the light source intersects the bounding box along each of first to third coordinate axes that define the 3D graphics environment based on the acquired information; and rendering the object in response to a result of the testing being that the ray intersects the bounding box along all of the first through third coordinate axes.
