摘要： Provided is a method and apparatus for rendering 3D graphics data. By calculating the size of a primitive, which is a basic constituent unit of objects indicated by the graphics data, on a screen, selecting one of a plurality of resolutions supported by a video stream according to the calculated size, generating a video frame image having the selected resolution from the video stream, and rendering the graphics data using the generated video frame image, the amount of memory space used and power consumed are reduced. In addition, since when rendering is performed using a video frame image decoded at a low resolution, a processing speed increases, and since rendering can be performed using video frame images decoded at various resolutions, image quality increases.
