Dynamic Pictures
{{Citation style, date=October 2019 Dynamic Pictures Inc. was a San Jose-based company which produced the Oxygen line of high-end 3D graphics cards. In 1997, they produced three PCI-based models: the Oxygen 102, Oxygen 202, and Oxygen 402. The Oxygen 202 and 402 featured an SLI-like design in providing two and four identical graphics processing units A graphics processing unit (GPU) is a specialized electronic circuit designed to manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device.

The four processor Oxygen 402 received a Viewperf CDRS-03 score of 42. In comparison, a much more recent GeForce FX GL (using a Geforce 5800-class GPU) achieves a 1803 on the same test. The list price for the Oxygen 102 was $1495 1996, later reduced to $399. References *"Dynamic Pictures", Computerw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3D Labs
3Dlabs was a fabless semiconductor company. It was founded in 1994 with headquarters in San Jose, California. It originally developed the GLINT and PERMEDIA high-end graphics chip technology, that was used on many of the world's leading computer graphics cards in the CAD and DCC markets, including its own Wildcat and Oxygen cards. In 2006 the company focused development efforts on its emerging media processing business, and in 2009 became the Singapore-based ZiiLABS. History 3Dlabs was formed from a management buy-out of Dupont Pixel Systems in the UK in April 1994 and went public on Nasdaq in October 1996. 3Dlabs acquired Dynamic Pictures in July 1998 and the Intense3D division of Intergraph in July 2000. It was itself acquired by Creative Labs in June 2002. In February 2006, 3Dlabs announced that it would stop developing professional 3D graphic chips and focus on embedded and mobile media processors. 3Dlabs was an early pioneer in bringing 3D graphics to the PC. Its GLINT ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dynamical Pictures
In quantum mechanics, dynamical pictures (or ''representations'') are the multiple equivalent ways to mathematically formulate the dynamics of a quantum system. The two most important ones are the Heisenberg picture and the Schrödinger picture. These differ only by a basis change with respect to time-dependency, analogous to the Lagrangian and Eulerian specification of the flow field: in short, time dependence is attached to quantum states in the Schrödinger picture and to operators in the Heisenberg picture. There is also an intermediate formulation known as the interaction picture (or Dirac picture) which is useful for doing computations when a complicated Hamiltonian has a natural decomposition into a simple "free" Hamiltonian and a perturbation. Equations that apply in one picture do not necessarily hold in the others, because time-dependent unitary transformations relate operators in one picture to the analogous operators in the others.

Scan-Line Interleave
Scan-Line Interleave (SLI) from 3dfx is a method for linking two (or more) video cards or chips together to produce a single output. It is an application of parallel processing for computer graphics, meant to increase the processing power available for graphics. SLI from 3dfx was introduced in 1998 and used in the Voodoo2 line of graphics accelerators. However, the original Voodoo Graphics card and the VSA-100 were also SLI-capable. Nvidia Corporation reintroduced the SLI acronym in 2004 (though it now stands for Scalable Link Interface). NVIDIA's SLI, compared to 3dfx's SLI, is modernized to use graphics cards interfaced over the PCI Express bus. Function 3dfx's SLI design was the first attempt, in the consumer PC market, at combining the rendering power of two video cards. The two 3dfx cards were connected by a small ribbon cable inside the PC. This cable shared graphics and synchronization information between the cards. Each 3dfx card rendered alternating horizontal lines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphics Processing Unit
A graphics processing unit (GPU) is a specialized electronic circuit designed to manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device. GPUs are used in embedded systems, mobile phones, personal computers, workstations, and game consoles. Modern GPUs are efficient at manipulating computer graphics and image processing. Their parallel structure makes them more efficient than general-purpose central processing units (CPUs) for algorithms that process large blocks of data in parallel. In a personal computer, a GPU can be present on a video card or embedded on the motherboard. In some CPUs, they are embedded on the CPU die. In the 1970s, the term "GPU" originally stood for ''graphics processor unit'' and described a programmable processing unit independently working from the CPU and responsible for graphics manipulation and output. Later, in 1994, Sony used the term (now standing for ''graphics processing unit'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
