A device for processing image data is disclosed. The device may determine a dominant texture with respect to each of a plurality of regions constituting an image. The device may group in a same group, from among the plurality of regions, regions in which the determined dominant texture is the same, and process allocated image data according to a result of grouping.

Method and device for processing image data

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.

Apparatus and method of rendering frame by adjusting processing sequence of draw commands

A tessellation method and apparatus are provided, where the tessellation method includes receiving a first value that is calculated in performing tessellation, the first value being a first floating-point real number represented by a first exponent and a first mantissa; determining a second precision of the first mantissa on the basis of a value of the first exponent and a first precision; and adjusting the first mantissa to have the second precision.

Tessellation apparatus and method

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.

Graphics data processing method and apparatus

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.

Method of generating and traversing acceleration structure

Methods and apparatus for ray tracing, and methods and apparatus for generating acceleration structure or traversing acceleration structure are provided. A method of generating an acceleration structure includes assigning objects into bounding boxes, generating an acceleration structure comprising nodes and indicating inclusion relationships between the bounding boxes, and marking overlapping nodes among the nodes.
