Bloom Lighting
Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in video games, demos, and high-dynamic-range rendering (HDRR) to reproduce an imaging artifact of real-world cameras. The effect produces fringes (or feathers) of light extending from the borders of bright areas in an image, contributing to the illusion of an extremely bright light overwhelming the camera or eye capturing the scene. It became widely used in video games after an article on the technique was published by the authors of ''Tron 2.0'' in 2004. Theory The physical basis of bloom is that, in the real world, lenses can never focus perfectly. Even a perfect lens will convolve the incoming image with an Airy disk (the diffraction pattern produced by passing a point light source through a circular aperture). Under normal circumstances, these imperfections are not noticeable, but an intensely bright light source will cause the imperfections to become visible. As a result, the image of the ...

Elephants Dream - Emo And Proog
Elephants are the largest existing land animals. Three living species are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. They are the only surviving members of the family Elephantidae and the order Proboscidea. The order was formerly much more diverse during the Pleistocene, but most species became extinct during the Late Pleistocene epoch. Distinctive features of elephants include a long proboscis called a trunk, tusks, large ear flaps, pillar-like legs, and tough but sensitive skin. The trunk is used for breathing, bringing food and water to the mouth, and grasping objects. Tusks, which are derived from the incisor teeth, serve both as weapons and as tools for moving objects and digging. The large ear flaps assist in maintaining a constant body temperature as well as in communication. African elephants have larger ears and concave backs, whereas Asian elephants have smaller ears, and convex or level backs. Elephants are ...

RGB Color Spaces
An RGB color space is any additive color space based on the RGB color model. An RGB color space is defined by chromaticity coordinates of the red, green, and blue additive primaries, the white point which is usually a standard illuminant, and the transfer function which is also known as the tone response curve (TRC) or gamma. Applying Grassmann's law of light additivity, a colorspace so defined can produce colors which are enclosed within the 2D triangle on the chromaticity diagram defined by those primary coordinates. The TRC and white point further define the possible colors, creating a volume in a 3D shape that never exceeds the triangular bounds. The primary colors are often specified in terms of their xyY chromaticity coordinates, though the uʹ,vʹ coordinates from the UCS chromaticity diagram may be used. Both xyY and uʹ,vʹ are derived from the CIE 1931 color space, a device independent space also known as XYZ which uses the 2° standard observer, an averaging of expe ...

Spring (game Engine)
The Spring Engine (also termed SpringRTS and formerly TA Spring), is a game engine for real-time strategy (RTS) video games. The game engine is free and open-source software, subject to the terms of the GNU General Public License v2.0 or later. History The development was initiated by Stefan Johansson, Tomaz Kunaver, and Jelmer Cnossen, members of the Swedish Yankspankers game clan under the name TA Spring. Since 2005 it is being developed by the community. The project aimed originally to bring the gameplay experience of Total Annihilation into three dimensions and to have the game run the mods and third-party units from Total Annihilation. The first release was on July 7, 2007, achieving its initial goals. Since then, the project evolved from a mere TA clone to a general RTS game engine including more flexible features like built-in high-level extensibility through a Lua scripting interface. Most of the games running on the engine (as of December 2010) are focused on multi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sauerbraten
Sauerbraten is a traditional German roast of heavily marinated meat. It is regarded as a national dish of Germany, and is frequently served in German-style restaurants internationally. It can be prepared from a variety of meats, most often from beef, but also from venison, lamb and mutton, pork and horse.Sheraton 1965, p. 147.Kummer 2007, p. 553. Before cooking, the raw meat is marinated for three to ten days in a mixture of vinegar or wine, water, herbs, spices, and seasonings. Usually, tougher cuts of meat such as rump roast or bottom round of beef are used, and the long marinating tenderizes the meat. A Sauerbraten dinner is almost always accompanied by a hearty gravy resulting from its roasting and is most often served with potato pancakes (''Kartoffelpuffer''), potato dumplings ('' Kartoffelklöße''), or ''Spätzle'' .Saekel 2005, F-5. Ingredients used in the marinade, and accompaniments served with sauerbraten, vary across regions. Regional variants of the dish include ...
