Bloom (shader effect)

Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in video games, demos and high dynamic range rendering (HDR) 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.

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 bright light appears to bleed beyond its natural borders.

The Airy disc function falls off very quickly but has very wide tails (actually, infinitely wide tails). As long as the brightness of adjacent parts of the image are roughly in the same range, the effect of the blurring caused by the Airy disc is not particularly noticeable; but in parts of the image where very bright parts are adjacent to relatively darker parts, the tails of the Airy disc become visible, and can extend far beyond the extent of the bright part of the image.

The Backyardigans

The Backyardigans is a Canadian–American CGI-animated musical TV series created by Janice Burgess, It is a co-production of animation studio Nelvana and Nickelodeon Animation Studios. The series debuted on October 11, 2004 and ended on May 31, 2010; reruns of The Backyardigans continued to air on the Nickelodeon family of channels in the United States until 2015. The show airs on Treehouse TV in Canada. In 2015, the first season was included as part of Nickelodeon's Noggin app, a mobile application featuring episodes of older Nick Jr. programs.

Plot

Austin 14

The Austin Fourteen is a 1.7-litre saloon that was introduced by Austin in August 1936 and available as a Goodwood saloon—with a fixed or sliding head—or as a Goodwood cabriolet. The body was of steel throughout. Nominally classed by Austin as a Fourteen the actual engine size attracted tax for a 16 horsepower car. The performance of the engine carried over from the Light Twelve-Six proved disappointing and a much smoother revised version with a near 20% improvement in power output was introduced the next year.

Equipment

The car was supplied with an adjustable steering column and body insulation. It comfortably carried four passengers with room for a small fifth passenger in the centre of the back seat. Even the quarter-lights were supplied with blinds, there were flush fitting footrests in the back of the large, adjustable, front seats with pull straps above. The back floor was flat except for the somewhat pronounced propellor shaft tunnel. The boot was provided with a fitted suitcase, the spare wheel sitting horizontally in the space below. The door could be let down and used as a luggage platform.

Austin 12/6

The Austin Light Twelve-Six is a 14 tax horsepower car with a 1496 cc engine that was introduced by Austin in January 1931. It was named by Austin Light Twelve to separate it from the well-established Austin Twelve. The general public then dubbed the original Twelve Heavy Twelve but Austin never used that name. The Light Twelve-Six remained in production until 1936.

In August 1936 the Austin Goodwood 14 (of 16 tax horsepower) with its "sound insulated coachwork" took the place of the Twelve-Six saloons. The tourers remained available. The Goodwood was also available as a separate chassis.

Six cylinders

There was among British car makers in the early 1930s a vogue for small capacity six-cylinder engines and the Light Twelve-Six was Austin's version. The side-valve engine was new and initially of 1496 cc capacity. Thermostatic control of the cooling system was added in September 1932. An increased 65.5 mm bore, larger capacity 1711 cc option was available at no extra charge from August 1933. Further details of these engines are in the panels at the right.

South (composition)

"South" is a jazz composition by Thamon Hayes and Bennie Moten. It was introduced by Bennie Moten's Kansas City Orchestra in 1924 and recorded again in 1928, when it became a national hit. It was Moten's most popular composition.

Moten's popular Victor 1928 recording of "South" (V-38021) stayed in Victor's catalog over the years (reissued as 24893 in 1935 as Victor phased out any remaining V-38000 series that were still in the catalog) and became a big jukebox hit in the late 1940s (by then, reissued as 44-0004). It remained in print (as a vinyl 45) until RCA stopping making records.

Originally an instrumental, Ray Charles later wrote lyrics for the tune.

Notes

Southern Italy

Southern Italy or Mezzogiorno (Italian pronunciation: [ˌmɛddzoˈdʒorno], literally "midday") is the traditional term for the southern regions of Italy, encompassing the southern section of the continental Italian Peninsula and the island of Sicily. It coincides with the administrative regions of Abruzzo, Apulia, Basilicata, Campania, Calabria, Molise, and Sicily. Some also include the most southern and eastern parts of Lazio (Sora, Cassino, Gaeta, Cittaducale and Amatrice districts) within the Mezzogiorno, because these territories were also part of the Kingdom of Two Sicilies. The island of Sardinia, although for cultural and historical reasons having less in common with the aforementioned regions, is frequently included as Southern Italy, often for statistical and economical purposes.

Southern Italy carries a unique legacy of culture. It features many major tourist attractions, such as the Palace of Caserta, the Amalfi Coast, Pompeii and other archaeological sites (many of which are protected by UNESCO). There are also many ancient Greek cities in Southern Italy, such as Sybaris, which were founded several centuries before the start of the Roman Republic. Some of its beaches, woodlands and mountains are preserved in several National Parks; a major example is La Sila, a mountainous plateau occupying the provinces of Cosenza and Catanzaro in the region of Calabria.
