ϕ is known as a velocity potential for u. A velocity potential is not unique. If ϕ is a velocity potential, then ϕ + f(t) is also a velocity potential for u, where f(t) is a scalar function of time and can be constant. Velocity potentials are unique up to a constant, or a function solely of the temporal variable.
A particular choice of the scalar and vector potentials is a gauge (more precisely, gauge potential) and a scalar function ψ used to change the gauge is called a gauge function. [citation needed] The existence of arbitrary numbers of gauge functions ψ(r, t) corresponds to the U(1) gauge freedom of this theory. Gauge fixing can be done in many ...
GameMaker (originally Animo, Game Maker (until 2011) and GameMaker Studio) is a series of cross-platform game engines created by Mark Overmars in 1999 and developed by YoYo Games since 2007. The latest iteration of GameMaker was released in 2022.
Game Maker's Toolkit (GMTK) is a video game analysis video series created by British journalist Mark Brown. Beginning in 2014, the series examines video game design and aims to encourage developers to improve their craft. It is hosted on YouTube and funded via Patreon. Additional topics include game accessibility and level design.
In electromagnetism, the Lorenz gauge condition or Lorenz gauge (after Ludvig Lorenz) is a partial gauge fixing of the electromagnetic vector potential by requiring = The name is frequently confused with Hendrik Lorentz , who has given his name to many concepts in this field. [ 1 ] (
Game-Maker (aka RSD Game-Maker) is an MS-DOS-based suite of game design tools, accompanied by demonstration games, produced between 1991 and 1995 by the Amherst, New Hampshire based Recreational Software Designs and sold through direct mail in the US by KD Software. [1]
Since velocity Verlet is a generally useful algorithm in 3D applications, a solution written in C++ could look like below. This type of position integration will significantly increase accuracy in 3D simulations and games when compared with the regular Euler method.
For a system of N particles in 3D real coordinate space, the position vector of each particle can be written as a 3-tuple in Cartesian coordinates: = (,,), = (,,), = (,,) Any of the position vectors can be denoted r k where k = 1, 2, …, N labels the particles.
