The axes of a two-dimensional Cartesian system divide the plane into four infinite regions, called quadrants, each bounded by two half-axes.
These are often numbered from 1st to 4th and denoted by Roman numerals: I (where the signs of the two coordinates are (+,+)), II (−,+), III (−,−), and IV (+,−). When the axes are drawn according to the mathematical custom, the numbering goes counter-clockwise starting from the upper right ("northeast") quadrant.
A Cartesian coordinate system is a coordinate system that specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular directed lines, measured in the same unit of length. Each reference line is called a coordinate axis or just axis of the system, and the point where they meet is its origin, usually at ordered pair (0, 0). The coordinates can also be defined as the positions of the perpendicular projections of the point onto the two axes, expressed as signed distances from the origin.
One can use the same principle to specify the position of any point in three-dimensional space by three Cartesian coordinates, its signed distances to three mutually perpendicular planes (or, equivalently, by its perpendicular projection onto three mutually perpendicular lines). In general, n Cartesian coordinates (an element of real n-space) specify the point in an n-dimensional Euclidean space for any dimension n. These coordinates are equal, up to sign, to distances from the point to n mutually perpendicular hyperplanes.
In technical drawing and computer graphics, a multiview orthographic projection is an illustration technique in which up to six pictures of an object are produced, with each projection plane parallel to one of the coordinate axes of the object.
The views are positioned relative to each other according to either of two schemes: first-angle or third-angle projection. In each, the appearances of views may be thought of as being projected onto planes that form a 6-sided box around the object.
Orthographic projections show the primary views of an object, each viewed in a direction parallel to one of the main coordinate axes. These primary views are called plans and elevations. Sometimes they are shown as if the object has been cut across or sectioned to expose the interior: these views are called sections.
Auxiliary views are sometimes taken from an angle that is not one of the primary views but these are not orthographic projections.
A plan is a view of a 3-dimensional object seen from vertically above (or sometimes below). It may be drawn in the position of a horizontal plane passing through, above, or below the object. The outline of a shape in this view is sometimes called its planform, for example with aircraft wings.
Warlord is the upcoming second studio album by Swedish rapper Yung Lean. It is expected to be released on February 25, 2016.
Warlord is an American heavy metal band, formed in 1980 and based in Los Angeles, California. Since its formation the band has been led by guitarist William J Tsamis and drummer Mark Zonder.
Warlord is the brainchild of guitarist/songwriter Bill Tsamis and drummer Mark Zonder, who had made their way down from San Jose, California to Los Angeles. The new band caught the attention of fledgling record company owner, Brian Slagel, whose label, Metal Blade Records, had recently issued Metal Massacre, a compilation featuring up and coming local metal bands such as Malice, Steeler, Ratt, and Metallica. An aficionado of the New Wave of British Heavy Metal and admirer of the European metal aesthetic, Slagel was impressed by Warlord's semi-progressive style inspired by such diverse acts as Rainbow, Angel Witch, and Jethro Tull. Slagel decided to offer the band a spot on his next compilation and Warlord would make their vinyl debut with "Lucifer's Hammer" on 1982's Metal Massacre II. Earning rave reviews, Warlord made a repeat appearance with "Mrs. Victoria" on Metal Massacre III and were signed to Metal Blade for their 1983 Deliver Us 6-song mini-album which got the band featured in important publications such as Kerrang!.
Norther was a Finnish melodic death metal band from Espoo, Finland. The band broke up in 2012.
Norther formed under the name Requiem (Lindroos, Korpas, Hallio) in 1996 after various early stage band formations. The band's debut effort was the album, Dreams of Endless War, released through Spinefarm Records in 2002. The album entered the Finnish charts at position 17. At the time, Norther was playing shows only in and around the Helsinki area. That changed when the album Mirror of Madness came out in early 2003 (entering the Finnish charts at position 11). The group toured with Dimmu Borgir and Hypocrisy in late 2003. In early 2004, Norther released its third full-length album, Death Unlimited, which reached 17 on the Finnish charts.
Norther played several shows in 2005 and then recorded an EP, Solution7 (recorded at Astia Studio). It landed in the official Finnish charts at position five. Norther added Kristian Ranta's vocals afterward. In the summer of 2005, Norther used Studio Fredman in Gothenburg, Sweden, to record their fourth full length-album named Till Death Unites Us, with producers Fredrik Nordström & Patrick J. Sten. Soon after recording the album, Toni Hallio left the band to pursue other interests; Heikki Saari replaced him at drums. After its release in January 2006, Till Death Unites Us was number six on the Finnish album charts. Later the same year, the band composed the theme song ("Frozen Angel") for a major Finnish feature film, V2: Dead Angel produced by Solarfilms, Inc. The band is also featured in the film. In February 2007 Norther released a new EP, No Way Back, released only in Finland and Japan. The record hit number one in the Finnish charts. Later that year the released Amoral & Drone, and supported it with a European tour.
