Embodiment Construction

[0053] The inventive concepts will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the inventive concepts are shown. Inventive concepts may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the inventive concept to those skilled in the art. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity. Like numbers refer to like elements throughout.

[0054] It will be understood that when an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly connected" or "directly coupled" to ano...

Abstract

A graphics processing unit includes a shader configured to perform one of tessellation and texturing. Shaders use geometric information for tessellation or texturing to generate a level of detail (LOD), and non-geometric information for tessellation or texturing to adjust the LOD.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2014-0136583 filed on October 10, 2014, the entire disclosure of which is hereby incorporated by reference. technical field [0003] Exemplary embodiments of the inventive concept relate to graphics processing techniques, and more particularly, to being able to use geometric information to calculate a level-of-detail (LOD) for tessellation or texturing and Graphics processing units (GPUs), methods of operating the GPUs, and devices including the GPUs are used to adjust the LOD using non-geometric information. Background technique [0004] In computer graphics, LOD involves adjusting image detail based on distance from the viewer. Such adjustments primarily take the form of reducing the complexity of the 3D object representation as the three-dimensional (3D) object moves away from the viewer. [0005] LOD technology increases the efficiency of rend...
