Patent application number | Description | Published |
20120075287 | Image processing apparatus and method - Provided is an image processing apparatus. The image processing apparatus may perform an intersection test for rendering of a ray tracing scheme. The image processing apparatus may include a first calculator and a second calculator. The first calculator may perform a ray-plane test to determine whether a ray intersects a plane including a primitive and a barycentric test to determine whether the ray intersects the primitive. The second calculator may calculate a hit point based on the ray which intersects the primitive. | 03-29-2012 |
20130207967 | IMAGE PROCESSING APPARATUS AND METHOD - Provided is an image processing apparatus. The image processing apparatus may determine whether a ray and a bounding volume including a primitive intersect each other, prior to determining whether the primitive and the ray intersect each other. An intersection test between the bounding volume and the ray may use a small amount of calculation compared to an intersection test between the primitive and the ray and thus, an amount of calculation used for rendering of the image processing apparatus may significantly decrease. | 08-15-2013 |
20140146042 | APPARATUS AND METHOD FOR PROCESSING PRIMITIVE IN THREE-DIMENSIONAL (3D) GRAPHICS RENDERING SYSTEM - An apparatus and method for processing a primitive in a three-dimensional (3D) graphics rendering system is provided. The primitive processing apparatus may discard a primitive or store the primitive in a memory, depending on whether a sampling point overlapping the primitive is present among sampling points in a pixel area. | 05-29-2014 |
20150095589 | CACHE MEMORY SYSTEM AND OPERATING METHOD FOR THE SAME - A cache memory system includes a cache memory, which stores cache data corresponding to portions of main data stored in a main memory and priority data respectively corresponding to the cache data; a table storage unit, which stores a priority table including information regarding access frequencies with respect to the main data; and a controller, which, when at least one from among the main data is requested, determines whether cache data corresponding to the request is stored in the cache memory, deletes one from among the cache data based on the priority data, and updates the cache data set with new data, wherein the priority data is determined based on the information regarding access frequencies. | 04-02-2015 |
20150097830 | IMAGE PROCESSING APPARATUS AND METHOD - An image processing method includes: determining whether a draw command that is identical to a previous draw command is input; obtaining information about a transparency of a previous frame that is performed with the previous draw command; and performing image processing on a current frame based on the information about the transparency. | 04-09-2015 |
20150103071 | METHOD AND APPARATUS FOR RENDERING OBJECT AND RECORDING MEDIUM FOR RENDERING - Provided are graphics data rendering methods. The method includes obtaining, at a graphics data renderer, first space information of at least one object corresponding to graphics data of a first frame, determining a sampling mode of the first frame, based on the graphics data, and rendering graphics data of a second frame based on the first space information and the sampling mode of the first frame. Thus, memory space and time that are used for rendering graphics data may be reduced. | 04-16-2015 |
20150228113 | GRAPHIC DATA RENDERING METHOD AND APPARATUS, AND RECORDING MEDIUM - A method and apparatus for rendering graphics data are provided. The graphics data rendering method includes calculating a number of overlapping objects by tile in a first frame. The graphics data rendering method determines a tile size of a second frame based on the calculated number of the overlapping objects, divides the second frame based on the determined tile size, and renders the second frame by divided tile. | 08-13-2015 |
20160078666 | METHOD AND APPARATUS FOR PROCESSING TEXTURE - A method and apparatus for processing a texture are provided. The method of processing the texture includes acquiring a texture address corresponding to a pixel address and frequency information of the texture, determining a number of texels to be used for texture filtering according to the frequency information of the texture, reading texel values corresponding to the determined number of texels based on the texture address, and performing the texture filtering by using the read texel values. | 03-17-2016 |
