A simulation is an imitative representation of a process or system that could exist in the real world. In this broad sense, simulation can often be used interchangeably with model. Sometimes a clear distinction between the two terms is made, in which simulations require the use of models; the model represents the key characteristics or behaviors of the selected system or process, whereas the simulation represents the evolution of the model over time. Another way to distinguish between the terms is to define simulation as experimentation with the help of a model. This definition includes time-independent simulations. Often, computers are used to execute the simulation.
Driving simulators are used for entertainment as well as in training of driver's education courses taught in educational institutions and private businesses. They are also used for research purposes in the area of human factors and medical research, to monitor driver behavior, performance, and attention and in the car industry to design and evaluate new vehicles or new advanced driver assistance systems.
A physics engine is computer software that provides an approximate simulation of certain physical systems, such as rigid body dynamics, soft body dynamics, and fluid dynamics, of use in the domains of computer graphics, video games and film (CGI). Their main uses are in video games, in which case the simulations are in real-time. The term is sometimes used more generally to describe any software system for simulating physical phenomena, such as high-performance scientific simulation.
The Open Dynamics Engine (ODE) is a physics engine written in C/C++. Its two main components are a rigid body dynamics simulation engine and a collision detection engine. It is free software licensed both under the BSD license and the LGPL.
The Blender Game Engine was a free and open-source 3D production suite used for making real-time interactive content. It was previously embedded within Blender, but support for it was dropped in 2019, with the release of Blender 2.8. The game engine was written from scratch in C++ as a mostly independent component, and includes support for features such as Python scripting and OpenAL 3D sound.
Computer animation physics or game physics are laws of physics as they are defined within a simulation or video game, and the programming logic used to implement these laws. Game physics vary greatly in their degree of similarity to real-world physics. Sometimes, the physics of a game may be designed to mimic the physics of the real world as accurately as is feasible, in order to appear realistic to the player or observer. In other cases, games may intentionally deviate from actual physics for gameplay purposes. Common examples in platform games include the ability to start moving horizontally or change direction in mid-air and the double jump ability found in some games. Setting the values of physical parameters, such as the amount of gravity present, is also a part of defining the game physics of a particular game.
SIMNET was a wide area network with vehicle simulators and displays for real-time distributed combat simulation: tanks, helicopters and airplanes in a virtual battlefield. SIMNET was developed for and used by the United States military. SIMNET development began in the mid-1980s, was fielded starting in 1987, and was used for training until successor programs came online well into the 1990s.
Simulation software is based on the process of modeling a real phenomenon with a set of mathematical formulas. It is, essentially, a program that allows the user to observe an operation through simulation without actually performing that operation. Simulation software is used widely to design equipment so that the final product will be as close to design specs as possible without expensive in process modification. Simulation software with real-time response is often used in gaming, but it also has important industrial applications. When the penalty for improper operation is costly, such as airplane pilots, nuclear power plant operators, or chemical plant operators, a mock up of the actual control panel is connected to a real-time simulation of the physical response, giving valuable training experience without fear of a disastrous outcome.
A robotics simulator is a simulator used to create an application for a physical robot without depending on the physical machine, thus saving cost and time. In some case, such applications can be transferred onto a physical robot without modification.
Web-based simulation (WBS) is the invocation of computer simulation services over the World Wide Web, specifically through a web browser. Increasingly, the web is being looked upon as an environment for providing modeling and simulation applications, and as such, is an emerging area of investigation within the simulation community.
The defense industry of Turkey has a long history, dated from the Ottoman Empire, and has changed several times during the Republic period.
Real-time simulation refers to a computer model of a physical system that can execute at the same rate as actual "wall clock" time. In other words, the computer model runs at the same rate as the actual physical system. For example, if a tank takes 10 minutes to fill in the real world, it would take 10 minutes to fill in the simulation as well.
Vortex Studio is a simulation software platform developed by CM Labs Simulations. It features a real-time physics engine that simulates rigid body dynamics, collision detection, contact determination, and dynamic reactions. It also contains model import and preparation tools, an image generator, and networking tools for distributed simulation which is accessed through a desktop editor via a GUI. Vortex adds accurate physical motion and interactions to objects in visual-simulation applications for operator training, mission planning, product concept validation, heavy machinery and robotics design and testing, haptics devices, immersive and virtual reality (VR) environments.
AGX Dynamics is a proprietary real-time physics engine developed by Algoryx Simulation AB that simulates rigid body dynamics, collision detection, dry frictional contacts, jointed systems, motors, fluids, deformable materials, hydraulics, hydrodynamics, cable systems and wires. AGX targets several domains, such as virtual reality real-time simulator applications for training and marketing; computer aided engineering and virtual prototyping; movie visual effects; and education. For education, components of AGX are used in the end-user software product Algodoo also developed and sold by Algoryx. Users of AGX simulate e.g. granular systems, construction equipment, forestry machines, mining processes and machines, biomechanics, industrial robots, ship and anchor handling processes and cranes. AGX is often integrated with 3D visualization frameworks such as OpenSceneGraph and OGRE and often also with actual hardware and control systems of the real-world version of the simulator. AGX is integrated in many 3D modeling and CAD systems, including Dynamics for SpaceClaim.
