Abstract: A method of generating an acceleration structure for ray tracing, the method including, using a processor, dividing a three-dimensional (3D) space including primitives into bounding boxes, obtaining position information of where the bounding boxes overlapping each other, and generating an acceleration structure representing the position information and an inclusion relation between the bounding boxes. Also disclosed is a related method of traversing an acceleration structure.

Abstract: Provided are methods and apparatuses for adjusting the processing sequence of draw commands for rendering images. The rendering method including determining, at a processing sequence determiner, previous draw commands that are identical to current draw commands; de-termining a processing sequence of the current draw commands based on depth information of the determined previous draw commands; and performing a Z-test on the current draw commands based on the processing sequence, and performing shading based on a result of the Z-test.

Abstract: A graphics data processing method and apparatus are disclosed. The graphics data processing method includes determining a guard band region having a distance range which is predetermined in a viewing direction from a position of a virtual camera, outside a virtualization region representing regions of objects able to be displayed on a screen among a plurality of objects included in graphics data. The method further includes acquiring position information of each of the plurality of objects, determining a region where at least one object among the plurality of objects is located, based on the acquired position information, and performing at least one of clipping and culling on data of the at least one object, based on the determined region.
