Frantic is a VIC-20 space shoot 'em up published by Imagine Software on cassette in 1982. A ZX Spectrum 48K version was planned, but never released. [1]
The player pilots a space ship while trying to keep an X and Y axis centered on the enemy, which enters the field of play at varying speeds and directions. Slower enemies appear horizontally and quicker enemies diagonally. The game's title alludes to the fact that the game is timed, as fuel levels deplete during play. Centering the X and Y axis to target enemies involves engaging thrusters which in turn burns fuel. The game can be played with either a joystick or keyboard.
In geometry, a Cartesian coordinate system in a plane is a coordinate system that specifies each point uniquely by a pair of real numbers called coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, called coordinate lines, coordinate axes or just axes of the system. The point where they meet is called the origin and has (0, 0) as coordinates.
A sphere is a geometrical object that is a three-dimensional analogue to a two-dimensional circle. Formally, a sphere is the set of points that are all at the same distance r from a given point in three-dimensional space. That given point is the center of the sphere, and r is the sphere's radius. The earliest known mentions of spheres appear in the work of the ancient Greek mathematicians.
Isometric projection is a method for visually representing three-dimensional objects in two dimensions in technical and engineering drawings. It is an axonometric projection in which the three coordinate axes appear equally foreshortened and the angle between any two of them is 120 degrees.
In mathematics, the upper half-plane, is the set of points in the Cartesian plane with The lower half-plane is the set of points with instead. Each is an example of two-dimensional half-space.
Fourier optics is the study of classical optics using Fourier transforms (FTs), in which the waveform being considered is regarded as made up of a combination, or superposition, of plane waves. It has some parallels to the Huygens–Fresnel principle, in which the wavefront is regarded as being made up of a combination of spherical wavefronts whose sum is the wavefront being studied. A key difference is that Fourier optics considers the plane waves to be natural modes of the propagation medium, as opposed to Huygens–Fresnel, where the spherical waves originate in the physical medium.
In non-Euclidean geometry, the Poincaré half-plane model is the upper half-plane, denoted below as H, together with a metric, the Poincaré metric, that makes it a model of two-dimensional hyperbolic geometry.
In geometry, a figure is chiral if it is not identical to its mirror image, or, more precisely, if it cannot be mapped to its mirror image by rotations and translations alone. An object that is not chiral is said to be achiral.
Reuven Ramaty High Energy Solar Spectroscopic Imager was a NASA solar flare observatory. It was the sixth mission in the Small Explorer program (SMEX), selected in October 1997 and launched on 5 February 2002, at 20:58:12 UTC. Its primary mission was to explore the physics of particle acceleration and energy release in solar flares.
Tornado Low Level is a multidirectional flight game developed by Costa Panayi and published in 1984 by the company he co-founded, Vortex Software. The game was first released for the ZX Spectrum, and later ported to the Amstrad CPC and Commodore 64.
Six degrees of freedom (6DOF), or sometimes six degrees of movement, refers to the six mechanical degrees of freedom of movement of a rigid body in three-dimensional space. Specifically, the body is free to change position as forward/backward (surge), up/down (heave), left/right (sway) translation in three perpendicular axes, combined with changes in orientation through rotation about three perpendicular axes, often termed yaw, pitch, and roll.
Cyclone is a multidirectional helicopter game for the ZX Spectrum released by Vortex Software in 1984. It was written by Vortex co-founder Costa Panayi who also coded the similarly styled Tornado Low Level.
In geometry, a point reflection is a transformation of affine space in which every point is reflected across a specific fixed point. When dealing with crystal structures and in the physical sciences the terms inversion symmetry, inversion center or centrosymmetric are more commonly used.
Lunar Rescue is an arcade game released by Taito in November 1979. The gameplay has some resemblance to both Taito's own 1978 hit Space Invaders and Atari, Inc.'s Lunar Lander.
Oids is a multidirectional shooter developed and self-published by FTL Games in 1987. The game was originally released on the Atari ST, followed by a B&W version for the classic 68k Macintosh in 1990. The Atari ST version, written by Dan Hewitt, was a cult favourite in the UK, where it received rave reviews.
WarpSpeed is a space flight simulator video game created by Accolade for the Sega Genesis/Mega Drive and Super NES.
In geometry, a line segment is a part of a straight line that is bounded by two distinct end points, and contains every point on the line that is between its endpoints. It is a special case of an arc, with zero curvature. The length of a line segment is given by the Euclidean distance between its endpoints. A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints. In geometry, a line segment is often denoted using an overline (vinculum) above the symbols for the two endpoints, such as in AB.
Isometric video game graphics are graphics employed in video games and pixel art that use a parallel projection, but which angle the viewpoint to reveal facets of the environment that would otherwise not be visible from a top-down perspective or side view, thereby producing a three-dimensional (3D) effect. Despite the name, isometric computer graphics are not necessarily truly isometric—i.e., the x, y, and z axes are not necessarily oriented 120° to each other. Instead, a variety of angles are used, with dimetric projection and a 2:1 pixel ratio being the most common. The terms "3/4 perspective", "3/4 view", "2.5D", and "pseudo 3D" are also sometimes used, although these terms can bear slightly different meanings in other contexts.
Superman: The Game is a 1985 video game designed by Fernando Herrera and published in the US by First Star Software for the Commodore 64. For European release, Superman was ported the Acorn Electron, Amstrad CPC, Atari 8-bit computers, BBC Micro, and ZX Spectrum.
Spacecraft attitude control is the process of controlling the orientation of a spacecraft with respect to an inertial frame of reference or another entity such as the celestial sphere, certain fields, and nearby objects, etc.
Hydra is a 1990 arcade vehicular combat video game developed and published by Atari Games. In Hydra, the player pilots a hovercraft, trying to deliver top secret items while avoiding mines, other hovercraft, and logs. The player can collect money and fuel to continue. X-Y yoke control.
