Matrox G200
The G200 is a 2D, 3D, and video accelerator chip for personal computers designed by Matrox. It was released in 1998. History Matrox had been known for years as a significant player in the high-end 2D graphics accelerator market. Cards they produced were excellent Windows accelerators, and some of the later cards such as Millennium and Mystique excelled at MS-DOS as well. Matrox stepped forward in 1994 with their ''Impression Plus'' to innovate with one of the first 3D accelerator boards, but that card only could accelerate a very limited feature set (no texture mapping), and was primarily targeted at CAD applications. Matrox, seeing the slow but steady growth in interest in 3D graphics on PCs with NVIDIA, Rendition, and ATI's new cards, began experimenting with 3D acceleration more aggressively and produced the Mystique. Mystique was their most feature-rich 3D accelerator in 1997, but still lacked key features including bilinear filtering. Then, in early 1998, Matrox teamed up wit ...

Matrox G400
The G400 is a video card made by Matrox, released in September 1999. The graphics processor contains a 2D Graphical user interface, GUI, video, and Direct3D 6.0 3D accelerator. Codenamed "Toucan", it was a more powerful and refined version of its predecessor, the Matrox G200, G200. Overview The Matrox G200 graphics processor had been a successful product, competing with the various 2D & 3D combination cards available in 1998. Matrox took the technology developed from the G200 project, refined it, and basically doubled it up to form the G400 processor. The new chip featured several new and innovative additions, such as multiple monitor output support, an all-around 32-bit rendering pipeline with high performance, further improved 2D and video acceleration, and a new 3D feature known as bump mapping, Environment Mapped Bump Mapping. Internally the G400 is a 256-bit processor, using what Matrox calls a "DualBus" architecture. This is an evolution of G200's "DualBus", which had been 1 ...

Quake II
''Quake II'' is a 1997 first-person shooter video game developed by id Software and published by Activision. It is the second installment of the ''Quake'' series, but not a direct sequel to '' Quake''. The game's storyline is continued in its expansions and '' Quake 4''. The soundtrack for ''Quake II'' was mainly provided by Sonic Mayhem, with some additional tracks by Bill Brown; the main theme was also composed by Bill Brown and Rob Zombie, and one track by Jer Sypult. The soundtrack for the Nintendo 64 version of the game was composed by Aubrey Hodges, credited as Ken "Razor" Richmond. Gameplay ''Quake II'' is a first-person shooter, in which the player shoots enemies from the perspective of the main character. The gameplay is very similar to that featured in ''Quake'', in terms of movement and controls, although the player's movement speed has been slowed down, and the player now has the ability to crouch. The game retains four of the eight weapons from ''Quake'' (th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenGL
OpenGL (Open Graphics Library) is a cross-language, cross-platform application programming interface (API) for rendering 2D and 3D vector graphics. The API is typically used to interact with a graphics processing unit (GPU), to achieve hardware-accelerated rendering. Silicon Graphics, Inc. (SGI) began developing OpenGL in 1991 and released it on June 30, 1992; applications use it extensively in the fields of computer-aided design (CAD), virtual reality, scientific visualization, information visualization, flight simulation, and video games. Since 2006, OpenGL has been managed by the non-profit technology consortium Khronos Group. Design The OpenGL specification describes an abstract API for drawing 2D and 3D graphics. Although it is possible for the API to be implemented entirely in software, it is designed to be implemented mostly or entirely in hardware. The API is defined as a set of functions which may be called by the client program, alongside a set of named in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
S3 Savage
Savage was a product-line of PC graphics chipsets designed by S3. Graphics Processors Savage 3D At the 1998 E3 Expo S3 introduced the first Savage product, Savage3D. Compared to its ViRGE-derived predecessor (Trio3D), Savage3D was a technological leap forward. Its innovative feature-set included the following: * "free" (single-cycle) trilinear-filtering * hardware motion-compensation and subpicture alpha-blending (MPEG-2 video) * integrated NTSC/PAL TV-encoder, (optional) Macrovision * S3 Texture Compression (S3TC) * multi-tap X/Y interpolating front-end ( BITBLT) and back-end (overlay) video-scaler Unfortunately for S3, deliveries of the Savage3D were hampered by poor manufacturing yields. Only one major board-vendor, Hercules, made any real effort to ship a Savage3D product. S3's yield problems forced Hercules to hand pick usable chips from the silicon wafers. Combined with poor drivers and the chip's lack of multitexturing support, the Savage3D failed in the market. ... [...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.

Heatsink
A heat sink (also commonly spelled heatsink) is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant, where it is dissipated away from the device, thereby allowing regulation of the device's temperature. In computers, heat sinks are used to cool CPUs, GPUs, and some chipsets and RAM modules. Heat sinks are used with high-power semiconductor devices such as power transistors and optoelectronics such as lasers and light-emitting diodes (LEDs), where the heat dissipation ability of the component itself is insufficient to moderate its temperature. A heat sink is designed to maximize its surface area in contact with the cooling medium surrounding it, such as the air. Air velocity, choice of material, protrusion design and surface treatment are factors that affect the performance of a heat sink. Heat sink attachment methods and thermal interface materials also affect the die temperature of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spatial Anti-aliasing
In digital signal processing, spatial anti-aliasing is a technique for minimizing the distortion artifacts ( aliasing) when representing a high-resolution image at a lower resolution. Anti-aliasing is used in digital photography, computer graphics, digital audio, and many other applications. Anti-aliasing means removing signal components that have a higher frequency than is able to be properly resolved by the recording (or sampling) device. This removal is done before (re)sampling at a lower resolution. When sampling is performed without removing this part of the signal, it causes undesirable artifacts such as black-and-white noise. In signal acquisition and audio, anti-aliasing is often done using an analog anti-aliasing filter to remove the out-of-band component of the input signal prior to sampling with an analog-to-digital converter. In digital photography, optical anti-aliasing filters made of birefringent materials smooth the signal in the spatial optical domain. The a ...

Trilinear Filtering
Trilinear filtering is an extension of the bilinear texture filtering method, which also performs linear interpolation between mipmaps. Bilinear filtering has several weaknesses that make it an unattractive choice in many cases: using it on a full-detail texture when scaling to a very small size causes accuracy problems from missed texels, and compensating for this by using multiple mipmaps throughout the polygon leads to abrupt changes in blurriness, which is most pronounced in polygons that are steeply angled relative to the camera. To solve this problem, trilinear filtering interpolates between the results of bilinear filtering on the two mipmaps nearest to the detail required for the polygon at the pixel. If the pixel would take up 1/100 of the texture in one direction, trilinear filtering would interpolate between the result of filtering the 128×128 mipmap as y1 with x1 as 128, and the result of filtering on the 64×64 mipmap as y2 with x2 as 64, and then interpolate to ...
