The award is named after Alan Turing, also referred as "Father of Computer Science", who was a British mathematician and Reader (academic rank), reader in mathematics at the University of Manchester. Turing is often credited as being the founder of theoretical computer science and artificial intelligence, and a key contributor to the Allied cryptanalysis of the Enigma cipher during World War II. From 2007 to 2013, the award was accompanied by a prize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cohen–Sutherland Algorithm
In computer graphics, the Cohen–Sutherland algorithm is an 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 viewport). The algorithm was developed in 1967 during flight simulator work by Danny Cohen and Ivan Sutherland.''Principles of Interactive Computer Graphics'', p. 124, 252, by Bob Sproull and William M. Newman, 1973, McGraw–Hill Education, International edition, . The algorithm The algorithm includes, excludes or partially includes the line based on whether: * Both endpoints are in the viewport region (bitwise OR of endpoints = 0000): trivial accept Trivia is information and data that are considered to be of little value. Modern usage of the term ''trivia'' dates to the 1960s, when college students introduced question-and-answer contests to their universities. A board game, ''Trivial Purs .... * Bot ...

Zooming User Interface
In computing, a zooming user interface or zoomable user interface (ZUI, pronounced zoo-ee) is a type of graphical user interface (GUI) where users can change the scale of the viewed area in order to see more detail or less, and browse through different documents. Information elements appear directly on an infinite virtual desktop (usually created using vector graphics), instead of in windows. Users can pan across the virtual surface in two dimensions and zoom into objects of interest. For example, as you zoom into a text object it may be represented as a small dot, then a thumbnail of a page of text, then a full-sized page and finally a magnified view of the page. ZUIs use zooming as the main metaphor for browsing through hyperlinked or multivariate information. Objects present inside a zoomed page can in turn be zoomed themselves to reveal further detail, allowing for recursive nesting and an arbitrary level of zoom. When the level of detail present in the resized obje ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sketchpad
Sketchpad (a.k.a. Robot Draftsman) is a computer program written by Ivan Sutherland in 1963 in the course of his PhD thesis, for which he received the Turing Award in 1988, and the Kyoto Prize in 2012. It pioneered human–computer interaction (HCI), and is considered the ancestor of modern computer-aided design (CAD) programs and as a major breakthrough in the development of computer graphics in general. For example, Sketchpad inspired the graphical user interface (GUI) and object-oriented programming. Using the program, Sutherland showed that computer graphics could be used for both artistic and technical purposes and for demonstrating a novel method of human–computer interaction. History See History of the graphical user interface for a more detailed discussion of GUI development. Software Sketchpad was the earliest program ever to use a complete graphical user interface. The clever way the program organizes its geometric data pioneered the use of ''master'' ( obj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interactive Computing
In computer science, interactive computing refers to software which accepts input from the user as it runs. Interactive software includes commonly used programs, such as word processors or spreadsheet applications. By comparison, non-interactive programs operate without user intervention; examples of these include compilers and batch processing applications that are pre-programmed to run independently. Interactive computing focuses on real-time interaction ("dialog") between the computer and the operator, and the technologies that enable them. If the response of the computer system is complex enough, it is said that the system is conducting social interaction; some systems try to achieve this through the implementation of social interfaces. The nature of interactive computing as well as its impact on users, are studied extensively in the field of computer interaction. History of interactive computing systems Ivan Sutherland is considered the father of interactive computi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Linear Transformation
Direct linear transformation (DLT) is an algorithm which solves a set of variables from a set of similarity relations: : \mathbf_ \propto \mathbf \, \mathbf_ for \, k = 1, \ldots, N where \mathbf_ and \mathbf_ are known vectors, \, \propto denotes equality up to an unknown scalar multiplication, and \mathbf is a matrix (or linear transformation) which contains the unknowns to be solved. This type of relation appears frequently in projective geometry. Practical examples include the relation between 3D points in a scene and their projection onto the image plane of a pinhole camera, and homographies. Introduction An ordinary system of linear equations : \mathbf_ = \mathbf \, \mathbf_ for \, k = 1, \ldots, N can be solved, for example, by rewriting it as a matrix equation \mathbf = \mathbf \, \mathbf where matrices \mathbf and \mathbf contain the vectors \mathbf_ and \mathbf_ in their respective columns. Given that there exists a unique ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Graphics
Computer graphics deals with generating images and art with the aid of computers.
