In computer graphics, tessellation is the dividing of datasets of polygons (sometimes called vertex sets) presenting objects in a scene into suitable structures for rendering. Especially for real-time rendering , data is tessellated into triangles , for example in OpenGL 4.0 and Direct3D 11 .
If a tessellation shader is in the graphics processing unit and active, the geometries in the scene can be subdivided. The calculated geometry is triangulated (subdivided into triangles). Triangles are broken down into fragment quads (one fragment quad is a 2 × 2 fragment primitive). Fragment quads are modified according to the fragment shader.
ATI TruForm was a brand by ATI (now AMD) for a SIP block capable of doing a graphics procedure called tessellation in computer hardware. ATI TruForm was included into Radeon 8500 (available from August 2001 on) and newer products.
The benchmark 3D scene is a steampunk-style city on flying islands in the middle of the clouds. The scene is GPU-intensive because of tessellation used for all the surfaces, dynamic sky with volumetric clouds and day-night cycle, real-time global illumination, and screen-space ambient occlusion.
Tessellation was officially specified in the major API's starting with DirectX 11 and OpenGL 4. TeraScale 1 based GPU's (HD 2000, 3000 and 4000 series) are only conformant to Direct3D 10 and OpenGL 3.3 and implements therefore a different tessellation principle which uses vendor specific API extensions.

The Maxwell architecture was introduced in later models of the GeForce 700 series and is also used in the GeForce 800M series, GeForce 900 series, and Quadro Mxxx series, as well as some Jetson produ
DirectX Raytracing (DXR) is a feature introduced in Microsoft's DirectX 12 that implements ray tracing, for video graphic rendering. DXR was released with the Windows 10 October update (version 1809) on October 10, 2018.
