In 3D computer graphics, shown-surface determination is the process used to determine which surfaces and parts of surfaces are not visible from a certain viewpoint. A hidden-surface determination algorithm is a solution to the visibility problem, which was one of the first major problems in the field of 3D computer graphics. The process of hidden-surface determination is sometimes called hiding, and such an algorithm is sometimes called a hider. The analogue for line rendering is hidden-line removal. Hidden-surface determination is necessary to render an image correctly, so that one may not view features hidden behind the model itself, allowing only the naturally viewable portion of the graphic to be visible.
Voice activity detection (VAD), also known as speech activity detection or speech detection, is a technique used in speech processing in which the presence or absence of human speech is detected. The main uses of VAD are in speech coding and speech recognition. It can facilitate speech processing, and can also be used to deactivate some processes during non-speech section of an audio session: it can avoid unnecessary coding/transmission of silence packets in Voice over Internet Protocol applications, saving on computation and on network bandwidth.
The Weiler–Atherton is a polygon-clipping algorithm. It is used in areas like computer graphics and games development where clipping of polygons is needed. It allows clipping of a subject or candidate polygon by an arbitrarily shaped clipping polygon/area/region.
Clipping, in the context of computer graphics, is a method to selectively enable or disable rendering operations within a defined region of interest. Mathematically, clipping can be described using the terminology of constructive geometry. A rendering algorithm only draws pixels in the intersection between the clip region and the scene model. Lines and surfaces outside the view volume are removed.
In computer graphics, the Liang–Barsky algorithm is a line clipping algorithm. The Liang–Barsky algorithm uses the parametric equation of a line and inequalities describing the range of the clipping window to determine the intersections between the line and the clip window. With these intersections it knows which portion of the line should be drawn. This algorithm is significantly more efficient than Cohen–Sutherland. The idea of the Liang–Barsky clipping algorithm is to do as much testing as possible before computing line intersections.
In computer graphics, line clipping is the process of removing lines or portions of lines outside an area of interest. Typically, any line or part thereof which is outside of the viewing area is removed.
Pfäfers is a municipality in the Wahlkreis (constituency) of Sarganserland in the canton of St. Gallen in Switzerland. The villages Pfäfers, St. Margrethenberg, Vadura, Valens, Vasön and Vättis belong to the municipality.
The Cohen–Sutherland algorithm is a computer-graphics algorithm used for line clipping. The algorithm divides a two-dimensional space into 9 regions and then efficiently determines the lines and portions of lines that are visible in the central region of interest.
The Nicholl–Lee–Nicholl algorithm is a fast line clipping algorithm that reduces the chances of clipping a single line segment multiple times, as may happen in the Cohen–Sutherland algorithm.
Vätti is a district of the city of Turku, in Finland. It is located to the north of the city centre. The area consists mostly of parkland, but there is also a high-density residential area in the district as well as some low-density developments. There is also an old people's home in Vätti.
Boolean operations on polygons are a set of Boolean operations operating on one or more sets of polygons in computer graphics. These sets of operations are widely used in computer graphics, CAD, and in EDA.
The Sutherland–Hodgman algorithm is a algorithm used for clipping polygons. It works by extending each line of the convex clip polygon in turn and selecting only vertices from the subject polygon that are on the visible side.
Elias Vattis is a Cypriot midfielder who plays for Karmiotissa. He started his career in AEL Limassol.
The Vatti clipping algorithm is used in computer graphics. It allows clipping of any number of arbitrarily shaped subject polygons by any number of arbitrarily shaped clip polygons. Unlike the Sutherland–Hodgman and Weiler–Atherton polygon clipping algorithms, the Vatti algorithm does not restrict the types of polygons that can be used as subjects or clips. Even complex (self-intersecting) polygons, and polygons with holes can be processed. The algorithm is generally applicable only in 2D space.
Vatti is a Chinese company which manufactures kitchen appliances. It manufactures gas hobs, water heaters and extractor fans.
The Cyrus–Beck algorithm is a generalized line clipping algorithm. It was designed to be more efficient than the Cohen–Sutherland algorithm, which uses repetitive clipping. Cyrus–Beck is a general algorithm and can be used with a convex polygon clipping window, unlike Sutherland–Cohen, which can be used only on a rectangular clipping area.
Unguturu Assembly constituency is a constituency in West Godavari district of Andhra Pradesh, representing the state legislative assembly in India. It is one of the seven assembly segments of Eluru, along with Denduluru, Eluru, Polavaram, Chintalapudi, Nuzvid and Kaikalur. Puppala Srinivasarao is the present MLA of the constituency, who won the 2019 Andhra Pradesh Legislative Assembly election from YSR Congress Party. As of 25 March 2019, there a total of 200,033 electors in the constituency.
The Greiner-Hormann algorithm is used in computer graphics for polygon clipping. It performs better than the Vatti clipping algorithm, but cannot handle degeneracies. It can process both self-intersecting and non-convex polygons. It can be trivially generalized to compute other Boolean operations on polygons, such as union and difference.
You-Dong Liang (梁友栋) is a mathematician and educator, best known for his contributions in geometric modeling and the Liang-Barsky algorithm.
