Spasim Gameplay
''Spasim'' is a 32-player 3D networked space flight simulation game and first-person space shooter developed by Jim Bowery for the PLATO computer network and released in March 1974. The game features four teams of eight players, each controlling a planetary system, where each player controls a spaceship in 3D space in first-person view. Two versions of the game were released: in the first, gameplay is limited to flight and space combat, and in the second systems of resource management and strategy were added as players cooperate or compete to reach a distant planet with extensive resources while managing their own systems to prevent destructive revolts. Although ''Maze'' is believed to be the earliest 3D game and first-person shooter as it had shooting and limited multiplayer by fall 1973, ''Spasim'' has been considered along with it to be one of the "joint ancestors" of the first-person shooter genre, due to uncertainty over ''Maze''s development timeline. The game was devel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Flight Simulation Game
A space flight simulation is a genre of flight simulator video games that lets players experience space flight to varying degrees of realism. Common mechanics include space exploration, space trade and space combat. Overview Some games in the genre aim to recreate a realistic portrayal of space flight, involving the calculation of orbits within a more complete physics simulation than pseudo space flight simulators. Others focus on gameplay rather than simulating space flight in all its facets. The realism of the latter games is limited to what the game designer deems to be appropriate for the gameplay, instead of focusing on the realism of moving the spacecraft in space. Some "flight models" use a physics system based on Newtonian physics, but these are usually limited to maneuvering the craft in its direct environment, and do not take into consideration the orbital calculations that would make such a game a simulator. Many of the pseudo simulators feature faster than light ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hidden-line Removal
In 3D computer graphics, solid objects are usually modeled by polyhedra. A face of a polyhedron is a planar polygon bounded by straight line segments, called edges. Curved surfaces are usually approximated by a polygon mesh. Computer programs for line drawings of opaque objects must be able to decide which edges or which parts of the edges are hidden by an object itself or by other objects, so that those edges can be clipped during rendering. This problem is known as hidden-line removal. The first known solution to the hidden-line problem was devised by L. G. Roberts in 1963. However, it severely restricts the model: it requires that all objects be convex. Ruth A. Weiss of Bell Labs documented her 1964 solution to this problem in a 1965 paper. In 1966 Ivan E. Sutherland listed 10 unsolved problems in computer graphics. Problem number seven was ''"hidden-line removal"''. In terms of computational complexity, this problem was solved by Devai in 1986.F. Devai. Quadratic bound ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown m ...

Cooperative Game Theory
In game theory, a cooperative game (or coalitional game) is a game with competition between groups of players ("coalitions") due to the possibility of external enforcement of cooperative behavior (e.g. through contract law). Those are opposed to non-cooperative games in which there is either no possibility to forge alliances or all agreements need to be self-enforcing (e.g. through credible threats). Cooperative games are often analysed through the framework of cooperative game theory, which focuses on predicting which coalitions will form, the joint actions that groups take and the resulting collective payoffs. It is opposed to the traditional non-cooperative game theory which focuses on predicting individual players' actions and payoffs and analyzing Nash equilibria. Cooperative game theory provides a high-level approach as it only describes the structure, strategies and payoffs of coalitions, whereas non-cooperative game theory also looks at how bargaining procedures wil ...

Metallurgy
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys. Metallurgy encompasses both the science and the technology of metals; that is, the way in which science is applied to the production of metals, and the engineering of metal components used in products for both consumers and manufacturers. Metallurgy is distinct from the craft of metalworking. Metalworking relies on metallurgy in a similar manner to how medicine relies on medical science for technical advancement. A specialist practitioner of metallurgy is known as a metallurgist. The science of metallurgy is further subdivided into two broad categories: chemical metallurgy and physical metallurgy. Chemical metallurgy is chiefly concerned with the reduction and oxidation of metals, and the chemical performance of metals. Subjects of study in chemical metallurgy inclu ...

Ron Resch
Ron Resch (Ronald Dale Resch) was an artist, computer scientist, and applied geometrist, known for his work involving folding paper, origami tessellations and 3D polyhedrons. Resch studied art at the University of Iowa receiving his Master of Fine Arts, and went on to become a professor of computer science at the University of Utah. He famously designed the Vegreville egg The Vegreville egg is a giant sculpture of a pysanka, a Ukrainian-style Easter egg. The work by Paul Maxym Sembaliuk is built of an intricate set of two-dimensional anodized aluminum tiles in the shape of Congruence (geometry), congruent equilater ..., the first physical structure designed entirely with computer-aided geometric modeling software.

Vector Graphics
Vector graphics is a form of computer graphics in which visual images are created directly from geometric shapes defined on a Cartesian plane, such as points, lines, curves and polygons. The associated mechanisms may include vector display and printing ''hardware'', vector ''data models'' and file formats, as well as the ''software'' based on these data models (especially graphic design software, computer-aided design, and geographic information systems). Vector graphics is an alternative to raster or bitmap graphics, with each having advantages and disadvantages in specific situations. While vector hardware has largely disappeared in favor of raster-based monitors and printers, vector data and software continues to be widely used, especially when a high degree of geometric precision is required, and when complex information can be decomposed into simple geometric primitives. Thus, it is the preferred model for domains such as engineering, architecture, surveying, 3D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moria (PLATO)
''Moria'' is a dungeon crawl style role-playing video game developed for the PLATO system beginning around 1975 by Kevet Duncombe and Jim Battin. In the game, up to ten players can simultaneously journey through a dynamically-generated dungeon, presented to the players in first-person wireframe 3D. Gameplay ''Moria'' allows parties of up to ten players to travel as a group and message each other, dynamically generating dungeons (instead of pre-computing them), and featuring a wireframe first-person perspective display. Development ''Moria'' was developed by Kevet Duncombe and Jim Battin beginning in either 1975 or 1976. The game was later given a copyright date of 1978. It was initially begun as a top-down two-dimensional dungeon crawl game, inspired by contemporary PLATO game '' Dnd'', which was developed beginning in 1975, and others such as ''Orthanc'' (1978). ''Moria'' was one of several '' Dungeons & Dragons''-inspired games on the PLATO network developed in the late 197 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Empire (PLATO)
''Empire'' is the name of a computer game written for the PLATO system in 1973. It is significant for being quite probably the first networked multiplayer arena shooter-style game. It may also be the first networked multiplayer action game (although '' Maze War'' is another possibility for this distinction). Gameplay Although PLATO terminals had touch panels, they did not have mice, and all control in the game is via typing. Commands involving directions to change course and fire weapons are entered as degree headings, with 0 being to the right, 90 up, 180 left, and 270 down. The "arrow" keys, clustered around "s", could also be used (e.g. "qw" being the same as 113 degrees). PLATO terminals had 512 by 512 pixel monochrome vector CRT display screens, and could use downloadable character sets to display graphics. The object of the game is to conquer the galaxy. This galaxy contains 25 planets and 4 races. The races were the Federation, Romulans, Orions, and (originally) Kli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mainframe Computer
A mainframe computer, informally called a mainframe or big iron, is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing. A mainframe computer is large but not as large as a supercomputer and has more processing power than some other classes of computers, such as minicomputers, servers, workstations, and personal computers. Most large-scale computer-system architectures were established in the 1960s, but they continue to evolve. Mainframe computers are often used as servers. The term ''mainframe'' was derived from the large cabinet, called a ''main frame'', that housed the central processing unit and main memory of early computers. Later, the term ''mainframe'' was used to distinguish high-end commercial computers from less powerful machines. Design Modern mainframe design is characterized less ...

Graphical Terminal
A computer terminal is an electronic or electromechanical hardware device that can be used for entering data into, and transcribing data from, a computer or a computing system. The teletype was an example of an early-day hard-copy terminal and predated the use of a computer screen by decades. Early terminals were inexpensive devices but very slow compared to punched cards or paper tape for input, yet as the technology improved and video displays were introduced, terminals pushed these older forms of interaction from the industry. A related development was time-sharing systems, which evolved in parallel and made up for any inefficiencies in the user's typing ability with the ability to support multiple users on the same machine, each at their own terminal or terminals. The function of a terminal is typically confined to transcription and input of data; a device with significant local, programmable data-processing capability may be called a "smart terminal" or fat client.
