3D computer graphics

With the birth of workstation computers came 3D computer graphics, based on vector graphics. Instead of the computer storing information about points, lines, and curves on a 2-dimensional plane, the computer stores the location of points, lines, and, typically, faces in 3-dimensional space.

3-dimensional polygons are the lifeblood of virtually all 3D computer graphics. As a result, most 3D graphics engines are based around storing points, lines that connect those points together, faces defined by the lines, and then a sequence of faces to create 3D polygons.Modern-day computer graphics software goes far beyond just the simple storage of polygons in computer memory. Today's graphics are not only the product of massive collections of polygons into identifiable shapes, but they also result from techniques in shading, texturing, and rasterization.

Competition in politics

Competition is also established in politics. In democracies, an election is a competition for an elected office. In other words, two or more candidates strive and compete against one another to attain a position of power. The winner gains the seat of the elected office for a set amount of time, when another election is generally held to determine the next holder of the office.
In addition, there is expected competition inside a government. Because several offices are appointed, potential candidates compete against the others in order to gain the particular office.
Departments may also compete for a limited amount of resources, such as for funding. Finally, where there are party systems, selected leaders of different parties will ultimately compete against the other party for laws, funding, and power.Finally, competition is also imminent between governments. Each country or nationality struggles for world dominance, power, or military strength. For example, the United States competed against the Soviet Union in the Cold War for world power, and the two also struggled over the different types of government.

Natural satellite

A natural satellite is a non-man-made object that orbits a planet or other body larger than itself. They are often called moons. The term natural satellite may also refer to a planet orbiting a star, as is the case with planets orbiting the Sun and even the Sun itself as it orbits the galactic center of the Milky Way. There are 240 known moons within the Solar system, including 162 orbiting the planets , 4 orbiting dwarf planets, and dozens more orbiting small solar system bodies. Other stars and their planets also have natural satellites.

The large gas giants have extensive systems of moons, including half a dozen comparable in size to Earth's moon. Of the inner planets, Mercury and Venus have no moons at all; Earth has one large moon ; and Mars has two tiny moons, Phobos and Deimos. Among the dwarf planets, Ceres has no moons, Eris has one, Dysnomia, and Pluto has three known satellites, Nix, Hydra, and a large companion called Charon. Charon is also unusual in that it does not orbit Pluto, but rather both bodies orbit a barycenter in empty space, making Pluto-Charon a binary system.

Black comedy

Black comedy is also known as black humor or dark comedy, is a sub-genre of comedy and satire where topics and events normally treat seriously – death, mass murder, sickness, madness, terror, drug abuse, rape, war etc. – are treated in a humorous or satirical manner. Synonyms created to avoid probable racial overtones include dark humor, morbid humor, gallows humor and off-color humor.

Black comedy is like to sick comedy, such as dead body jokes. However, in sick humor most of the humor comes from shock and revulsion; black humor usually includes an element of irony, or even fatalism. This particular brand of humor can be exemplified by a scene in the play waiting for Godot: men take off his belt to hang him, and his trousers fall down. Another example, "Suicide just isn't funny, no matter which way you slice it," is an effective satire at the way that suicide is treated in mainstream western culture, insinuating that attitudes towards suicide are still more morose or morbid than the act or mental condition leading to it.
