Tessellation definition quizlet9/26/2023 ![]() These examples are programmatically compiled from various online sources to illustrate current usage of the word 'tessellation.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. Brian Westover, PCMAG, 8 July 2022 See More 2016 Both exercise graphics and compute shaders, but one focuses on hardware tessellation and the other on the OpenGL application programming interface (API). Nathaniel Scharping, Discover Magazine, 19 Dec. The distance (in meters) to the Camera at which tessellation begins to fade out. If you want more aggressive culling and better performance, set this to a higher value. If you want to disable back-face culling, set this to -1.0. 2022 The true impact of roads seems to be the gradual tessellation of once-cohesive landscapes. Specifies how HDRP culls tessellated triangles. Nathaniel Scharping, Discover Magazine, 29 Nov. 2023 The path of the International Space Station, as mapped over a tessellation of Narukawa's world map. 2023 Closerie Falbala was made to energise, and stepping inside feels like being within an ornament, a tender space, Logological Cabinet, was meant to be an intense experience, painted in his L'Hourloupe style from floor to ceiling in swirling tessellations. Manon Bischoff, Scientific American, 10 Apr. Adrienne Bernhard, Popular Mechanics, 15 June 2023 This tells us that the tessellation must be aperiodic. Elise Cutts, Quanta Magazine, 21 June 2023 The concept of aperiodic geometry has existed for at least 1,000 years from Islamic mosaics and tessellations to ancient marquetry designs and silk weavings. Manon Bischoff, Scientific American, 22 June 2023 Each tessellation should plot to exactly one point within the plane. If you want to do any further work on the primitives, you can add a Geometry shader.Recent Examples on the Web Doris Schattschneider, a retired mathematician affiliated with Moravian University with expertise in tessellations, had been skeptical about the likelihood of a true einstein ever being discovered. It is guaranteed to be called at least once for each generated vertex. This shader can also be used to do all sorts of per-vertex calculations just like a vertex shader. In this shader, you set the type of primitive you want to generate and how the vertices are spaced and many other things. Lastly, the Tessellation Evaluation Shader is called for each newly generated vertex. Then the hardware tessellator divides the geometry according to the Control Shader. In the Tesselation Control shader you set the type and number of subdivisions. The first and the last stage is programmable, the actual tesselation is done by the hardware in a fixed function stage. In OpenGL, they are called the Tessellation Control Shader, Tesselation Primitive Generation, and the Tessellation Evaluation Shader. In DirectX, it is the Hull Shader, Hardware Tessellation, and the Domain Shader. ![]() ![]() The terms for each stage varies based on the API. Tesselation is done in multiple stages, and it is done AFTER the vertex shader. Most of the time this tesselation is done anew in each single frame and this could be the reason that your frame-rate drops once you enable this. This allows you to load a relatively coarse mesh on your graphics card, generate more vertices and triangles dynamically and then have a mesh on the screen that looks much smoother. Specifically, it lets you repeatedly subdivide the current geometry into a finer mesh. Tesselation is a technique that allows you to generate primitives (triangles, lines, points and such) on the graphics-card.
