The most common purpose of the Turbo SIM is to spoof the IMSI number and authentication key (Ki) supplied by the SIM card to the network, allowing phones locked to use only a particular network such as the Apple iPhone, [4] [5] [6] and more recently NTT DoCoMo and SoftBank phones, to be used on any mobile network with which they are technically ...
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
Graphics represented as a rectangular grid of pixels. Rasterization Converting vector graphics to raster graphics. This terms also denotes a common method of rendering 3D models in real time. Ray casting Rendering by casting non-recursive rays from the camera into the scene. 2D ray casting is a 2.5D rendering method. Ray marching
Single instruction, multiple data. Single instruction, multiple data (SIMD) is a type of parallel processing in Flynn's taxonomy.SIMD can be internal (part of the hardware design) and it can be directly accessible through an instruction set architecture (ISA), but it should not be confused with an ISA.
Most computer, logic-test and fault-tree simulations are of this type. In this type of simulation, the simulator maintains a queue of events sorted by the simulated time they should occur. The simulator reads the queue and triggers new events as each event is processed. It is not important to execute the simulation in real time.
BGI was accessible in C/C++ with graphics.lib / graphics.h, and in Pascal via the graph unit. BGI was less powerful than modern graphics libraries such as SDL or OpenGL, since it was designed for 2D presentation graphics instead of event-based 3D applications. However, it has been considered simpler to code.
A physics engine is computer software that provides an approximate simulation of certain physical systems, typically classical dynamics, including rigid body dynamics (including collision detection), soft body dynamics, and fluid dynamics. It is of use in the domains of computer graphics, video games and film .
Kristen Nygaard was invited to visit the Eckert–Mauchly Computer Corporation in late May 1962 in connection with the marketing of their new UNIVAC 1107 computer. At that visit, Nygaard presented the ideas of Simula to Robert Bemer, the director of systems programming at Univac. Bemer was a great ALGOL fan and found the Simula project compelling.
