Especially for real-time rendering, data is tessellated into triangles, for example in OpenGL and DirectX 11.〔(The OpenGL® Graphics System: A Specification (Version 4.0 (Core Profile) - March 11, 2010) )〕〔(MSDN: Tessellation Overview )〕 ==In graphics rendering== A key advantage of tessellation for realtime graphics is that it allows detail to be dynamically added and subtracted from a 3D mesh and its silhouette edges based on control parameters (often camera distance). In previously leading realtime techniques such as parallax mapping and bump mapping, surface details could be simulated at the pixel level, but silhouette edge detail was fundamentally limited by the quality of the original dataset. In Direct3D 11 pipeline (a part of DirectX 11), the graphics primitive is the patch. The ''tessellator'' generates a triangle-based tessellation of the patch according to tessellation parameters such as the ''TessFactor'', which controls the degree of fineness of the mesh. The tessellation, along with shaders such as a Phong shader, allows for producing smoother surfaces than would be generated by the original mesh.〔 By offloading the tessellation process onto the GPU hardware, smoothing can be performed in real time. Tessellation can also be used for implementing subdivision surfaces, level of detail scaling and fine displacement mapping. OpenGL uses a similar pipeline, where tessellation into triangles is controlled by the ''Tessellation Control Shader'' and a set of four tessellation parameters.〔(【引用サイトリンク】url=http://www.opengl.org/wiki/Tessellation#Tessellation_control_shader )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tessellation (computer graphics)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
