Transparency (optics)
In the field of optics, transparency (also called pellucidity or diaphaneity) is the physical property of allowing light to pass through the material without appreciable scattering of light. On a macroscopic scale (one in which the dimensions are much larger than the wavelengths of the photons in question), the photons can be said to follow Snell's law. Translucency (also called translucence or translucidity) allows light to pass through, but does not necessarily (again, on the macroscopic scale) follow Snell's law; the photons can be scattered at either of the two interfaces, or internally, where there is a change in index of refraction. In other words, a translucent material is made up of components with different indices of refraction. A transparent material is made up of components with a uniform index of refraction. Transparent materials appear clear, with the overall appearance of one color, or any combination leading up to a brilliant spectrum of every color. The opposite ...

Transparent (book)
Cris Beam is an American writer. She is the author of nonfiction books on transgender teenagers, the U.S. foster system, and empathy, as well as a young adult novel and a short memoir. Life Beam was a volunteer teacher at EAGLES Academy for two and a half years, a former public high school for LGBT students in Los Angeles. She has an adoptive daughter. Books ''Transparent'' In 2007, Beam published ''Transparent: Love, Family, and Living the T with Transgender Teenagers''. The non-fiction book describes four transgender teenage girls; ''The New York Times'' said, "With sensitivity and a deep connection to the girls, Beam describes their struggles with transitioning and how they reconcile them with more familiar teenage concerns like crushes and cliques." Beam, a journalist from New York City, began the book after moving to Los Angeles where her partner was in graduate school and Beam began volunteering at a high school for gay and trans teenagers. ''Transparent'' won the 2008 Trans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Order-independent Transparency
Order-independent transparency (OIT) is a class of techniques in rasterisational computer graphics for rendering transparency in a 3D scene, which do not require rendering geometry in sorted order for alpha compositing. Description Commonly, 3D geometry with transparency is rendered by blending (using alpha compositing) all surfaces into a single buffer (think of this as a canvas). Each surface occludes existing color and adds some of its own color depending on its ''alpha'' value, a ratio of light ''transmittance''. The order in which surfaces are blended affects the total occlusion or ''visibility'' of each surface. For a correct result, surfaces must be blended from farthest to nearest or nearest to farthest, depending on the alpha compositing operation, ''over'' or ''under''. Ordering may be achieved by rendering the geometry in sorted order, for example sorting triangles by depth, but can take a significant amount of time, not always produce a solution (in the case of inter ...

Location Transparency
In computer networks, location transparency is the use of names to identify network resources, rather than their actual location. For example, files are accessed by a unique file name, but the actual data is stored in physical sectors scattered around a disk in either the local computer or in a network. In a location transparency system, the actual location where the file is stored doesn't matter to the user. A distributed system A distributed system is a system whose components are located on different networked computers, which communicate and coordinate their actions by passing messages to one another from any system. Distributed computing is a field of computer sci ... will need to employ a networked scheme for naming resources. The main benefit of location transparency is that it no longer matters where the resource is located. Depending on how the network is set, the user may be able to obtain files that reside on another computer connected to the particular network. This ...

Pseudo-transparency
''Pseudo-transparency'' is a term used for X Window System clients that simulate the appearance of translucency or transparency by manipulating the same pixmap that has been drawn on the root window, or by instructing the X Server that the Background Pixmap should be inherited from the window's parent. Purpose Traditionally, the X Window System has lagged behind other windowing systems in adding purely eye candy or aesthetic features, such as window translucency. This has encouraged developers to develop kludges to overcome this limitation. This pseudo-transparency, so called as the background pixmap of the root window is visible (analogous to desktop wallpaper) rather than any obscured windows, allows users to make windows look less imposing (such as Terminal emulators, which usually comprise large chunks of text), and to integrate the appearance of windows with their desktop themes. Implementation There are three common methods for achieving pseudo-transparency using Xlib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transparency (graphic)
Transparency in computer graphics is possible in a number of file formats. The term " transparency" is used in various ways by different people, but at its simplest there is "full transparency" i.e. something that is completely invisible. Only part of a graphic should be fully transparent, or there would be nothing to see. More complex is "partial transparency" or "translucency" where the effect is achieved that a graphic is partially transparent in the same way as colored glass. Since ultimately a printed page or computer or television screen can only be one color at a point, partial transparency is always simulated at some level by mixing colors. There are many different ways to mix colors, so in some cases transparency is ambiguous. In addition, transparency is often an "extra" for a graphics format, and some graphics programs will ignore the transparency. Raster file formats that support transparency include GIF, PNG, BMP, TIFF, TGA and JPEG 2000, through either a ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Image Mask
In computer science, a mask or bitmask is data that is used for bitwise operations, particularly in a bit field. Using a mask, multiple bits in a byte, nibble, word, etc. can be set either on or off, or inverted from on to off (or vice versa) in a single bitwise operation. An additional use of masking involves predication in vector processing, where the bitmask is used to select which element operations in the vector are to be executed (mask bit is enabled) and which are not (mask bit is clear). Common bitmask functions Masking bits to 1 To turn certain bits on, the bitwise OR operation can be used, following the principle that Y OR 1 = 1 and Y OR 0 = Y. Therefore, to make sure a bit is on, OR can be used with a 1. To leave a bit unchanged, OR is used with a 0. Example: Masking ''on'' the higher nibble (bits 4, 5, 6, 7) while leaving the lower nibble (bits 0, 1, 2, 3) unchanged. 10010101 10100101 OR 11110000 11110000 = 11110101 11110101 Masking bits to 0 ...

Alpha Compositing
In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. It is often useful to render picture elements (pixels) in separate passes or layers and then combine the resulting 2D images into a single, final image called the composite. Compositing is used extensively in film when combining computer-rendered image elements with live footage. Alpha blending is also used in 2D computer graphics to put rasterized foreground elements over a background. In order to combine the picture elements of the images correctly, it is necessary to keep an associated ''matte'' for each element in addition to its color. This matte layer contains the coverage information—the shape of the geometry being drawn—making it possible to distinguish between parts of the image where something was drawn and parts that are empty. Although the most basic operation of combining two images is t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latch (electronics)
In electronics, a flip-flop or latch is a circuit that has two stable states and can be used to store state information – a bistable multivibrator. The circuit can be made to change state by signals applied to one or more control inputs and will have one or two outputs. It is the basic storage element in sequential logic. Flip-flops and latches are fundamental building blocks of digital electronics systems used in computers, communications, and many other types of systems. Flip-flops and latches are used as data storage elements. A flip-flop is a device which stores a single '' bit'' (binary digit) of data; one of its two states represents a "one" and the other represents a "zero". Such data storage can be used for storage of ''state'', and such a circuit is described as sequential logic in electronics. When used in a finite-state machine, the output and next state depend not only on its current input, but also on its current state (and hence, previous inputs). It can also ...

Network Transparency
Network transparency, in its most general sense, refers to the ability of a protocol to transmit data over the network in a manner which is not observable (“ transparent” as in invisible) to those using the applications that are using the protocol. In this way, users of a particular application may access remote resources in the same manner in which they would access their own local resources. An example of this is cloud storage, where remote files are presented as being locally accessible, and cloud computing where the resource in question is processing. X Window The term is often partially correctly applied in the context of the X Window System, which is able to transmit graphical data over the network and integrate it seamlessly with applications running and displaying locally; however, certain extensions of the X Window System are not capable of working over the network. Databases In a centralized database system, the only available resource that needs to be shielded from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transparency (telecommunication)
In telecommunications, ''transparency'' can refer to: #The property of an entity that allows another entity to pass through it without altering either of the entities. #The property that allows a transmission system or channel to accept, at its input, unmodified user information, and deliver corresponding user information at its output, unchanged in form or information content. The user information may be changed internally within the transmission system, but it is restored to its original form prior to the output without the involvement of the user. #The quality of a data communications system or device that uses a bit-oriented link protocol that does not depend on the bit sequence structure used by the data source. Some communication systems are not transparent. Non-transparent communication systems have one or both of the following problems: * user data may be incorrectly interpreted as internal commands. For example, modems with a Time Independent Escape Sequence or 20th c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transparency (human–computer Interaction)
Any change in a computing system, such as a new feature or new component, is transparent if the system after change adheres to previous external interface as much as possible while changing its internal behaviour. The purpose is to shield from change all systems (or human users) on the other end of the interface. Confusingly, the term refers to overall ''invisibility'' of the component, it does not refer to ''visibility of component's internals'' (as in white box or open system). The term ''transparent'' is widely used in computing marketing in substitution of the term ''invisible'', since the term ''invisible'' has a bad connotation (usually seen as something that the user can't see and has no control over) while the term ''transparent'' has a good connotation (usually associated with not hiding anything). The vast majority of the times, the term ''transparent'' is used in a misleading way to refer to the actual invisibility of a computing process, which is also described by t ...
