3D Mark
3DMark is a computer benchmarking tool created and developed by UL, (formerly Futuremark), to determine the performance of a computer's 3D graphic rendering and CPU workload processing capabilities. Running 3DMark produces a 3DMark score, with higher numbers indicating better performance. The 3DMark measurement unit is intended to give a normalized means for comparing different PC hardware configurations (mostly graphics processing units and central processing units), which proponents such as gamers and overclocking enthusiasts assert is indicative of end-user performance capabilities. Many versions of 3DMark have been released since 1998. Scores cannot be compared across versions as each test is based on a specific version of the DirectX API. Versions See also * Benchmark (computing) * PCMark * Futuremark Futuremark Oy was a Finnish software development company that produced computer benchmark applications for home, business, and press use.

Computer Benchmark
In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it. The term ''benchmark'' is also commonly utilized for the purposes of elaborately designed benchmarking programs themselves. Benchmarking is usually associated with assessing performance characteristics of computer hardware, for example, the floating point operation performance of a CPU, but there are circumstances when the technique is also applicable to software. Software benchmarks are, for example, run against compilers or database management systems (DBMS). Benchmarks provide a method of comparing the performance of various subsystems across different chip/system architectures. Purpose As computer architecture advanced, it became more difficult to compare the performance of various computer systems simply by looking at their specific ...

1998 Software
1998 was designated as the ''International Year of the Ocean''. Events January * January 6 – The ''Lunar Prospector'' spacecraft is launched into orbit around the Moon, and later finds evidence for frozen water, in soil in permanently shadowed craters near the Moon's poles. * January 11 – Over 100 people are killed in the Sidi-Hamed massacre in Algeria. * January 12 – Nineteen European nations agree to forbid human cloning. * January 17 – The ''Drudge Report'' breaks the story about U.S. President Bill Clinton's alleged affair with Monica Lewinsky, which will lead to the House of Representatives' impeachment of him. February * February 3 – Cavalese cable car disaster: A United States military pilot causes the deaths of 20 people near Trento, Italy, when his low-flying EA-6B Prowler severs the cable of a cable-car. * February 4 – The 5.9 Afghanistan earthquake shakes the Takhar Province with a maximum Mercalli intensity of VII (''Very strong'').

PCMark
PCMark is a computer benchmark tool developed by UL (formerly Futuremark) to test the performance of a PC at the system and component level. In most cases, the tests in PCMark are designed to represent typical home user workloads. Running PCMark produces a score with higher numbers indicating better performance. Several versions of PCMark have been released. Scores cannot be compared across versions since each includes different tests. Versions Controversy In a 2008 ''Ars Technica'' article, a VIA Nano gained significant performance after its CPUID changed to Intel. This was because Intel compilers create conditional code that uses more advanced instructions for CPUs that identify as Intel.

Futuremark was acquired by UL on 31 October 2014, and was formally merged into the compa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Direct3D
Direct3D is a graphics application programming interface (API) for Microsoft Windows. Part of DirectX, Direct3D is used to render three-dimensional graphics in applications where performance is important, such as games. Direct3D uses hardware acceleration if it is available on the graphics card, allowing for hardware acceleration of the entire 3D rendering pipeline or even only partial acceleration. Direct3D exposes the advanced graphics capabilities of 3D graphics hardware, including Z-buffering, W-buffering, stencil buffering, spatial anti-aliasing, alpha blending, color blending, mipmapping, texture blending, clipping, culling, atmospheric effects, perspective-correct texture mapping, programmable HLSL shaders and effects. Integration with other DirectX technologies enables Direct3D to deliver such features as video mapping, hardware 3D rendering in 2D overlay planes, and even sprites, providing the use of 2D and 3D graphics in interactive media ties. Direct3D contains many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thread (computer Science)
In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system. The implementation of threads and processes differs between operating systems. In Modern Operating Systems, Tanenbaum shows that many distinct models of process organization are possible.TANENBAUM, Andrew S. Modern Operating Systems. 1992. Prentice-Hall International Editions, ISBN 0-13-595752-4. In many cases, a thread is a component of a process. The multiple threads of a given process may be executed concurrently (via multithreading capabilities), sharing resources such as memory, while different processes do not share these resources. In particular, the threads of a process share its executable code and the values of its dynamically allocated variables and non- thread-local global variables at any given time. History Threads made an early appearance under the name of "tasks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subsurface Scattering
Subsurface scattering (SSS), also known as subsurface light transport (SSLT), is a mechanism of light transport in which light that penetrates the surface of a translucent object is scattered by interacting with the material and exits the surface at a different point. The light will generally penetrate the surface and be reflected a number of times at irregular angles inside the material before passing back out of the material at a different angle than it would have had if it had been reflected ''directly'' off the surface. Subsurface scattering is important for realistic 3D computer graphics, being necessary for the rendering of materials such as marble, skin, leaves, wax and milk. If subsurface scattering is not implemented, the material may look unnatural, like plastic or metal. Rendering techniques To improve rendering efficiency, many real-time computer graphics algorithms only compute the reflectance at the *surface* of an object. In reality, many materials are slightly t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strauss Lighting Model
Strauss, Strauß or Straus is a common Germanic surname. Outside Germany and Austria ''Strauß'' is always spelled ''Strauss'' (the letter " ß" is not used in the German-speaking part of Switzerland). In classical music, "Strauss" usually refers to Richard Strauss or Johann Strauss II. The name has been used by families in the Germanic area for at least a thousand years. The overlord of Gröna, for example, went by the name of Struz and used the image of an ostrich as his symbol. Examples of it could still be seen on the thousand-year-old church bell of that town. "Struz" or "Strutz" is the North-German form of the word "Strauss", which is the modern German word for ostrich. Some of the earliest Jewish bearers of the name hailed from the Judengasse in medieval Frankfurt, where families have been known by the name of the houses they inhabited. All the houses had names and these included Haus Strauss, complete with an image of an ostrich on the façade. When, for tax purposes, ...
