GeForce2
The GeForce 2 series (NV15) is the second generation of Nvidia's GeForce line of graphics processing units (GPUs). Introduced in 2000, it is the successor to the GeForce 256. The GeForce 2 family comprised a number of models. The ''GeForce 2 GTS'', ''GeForce 2 Ultra'', ''GeForce 2 Pro'', and ''GeForce 2 Ti'' are based upon the original architecture (NV15), varying only by chip and memory clock speeds. For the low-end segment and OEMs, the ''GeForce 2 MX'' series (NV11) was created, from which the ''GeForce 2 Go'' was derived for laptops. In addition, the GeForce 2 architecture is used for the Quadro series on the Quadro 2 Pro, 2 MXR, and 2 EX cards with special drivers meant to accelerate computer-aided design applications. Architecture The GeForce 2 architecture (NV15) is similar to the previous GeForce 256 line but with various improvements. Compared to the 220 nm GeForce 256, the GeForce 2 is built on a 180 nm manufacturing process, making the silicon more dense and a ...

GeForce 4 Series
The GeForce 4 series (codenames below) refers to the fourth generation of Nvidia's GeForce line of graphics processing units (GPUs). There are two different GeForce4 families, the high-performance Ti family (NV25), and the budget MX family (NV17). The MX family spawned a mostly identical GeForce4 Go (NV17M) family for the laptop market. All three families were announced in early 2002; members within each family were differentiated by core and memory clock speeds. In late 2002, there was an attempt to form a fourth family, also for the laptop market, the only member of it being the GeForce4 4200 Go (NV28M) which was derived from the Ti line. GeForce4 Ti Architecture The GeForce4 Ti (NV25) was launched in February 2002 and was a revision of the GeForce 3 (NV20). It was very similar to its predecessor; the main differences were higher core and memory clock rates, a revised memory controller (known as Lightspeed Memory Architecture II/LMA II), Direct3D 8.1 support with up to Pi ...

GeForce
GeForce is a brand of graphics processing units (GPUs) designed by Nvidia and marketed for the performance market. As of the GeForce 50 series, there have been nineteen iterations of the design. In August 2017, Nvidia stated that "there are over 200 million GeForce gamers". The first GeForce products were discrete GPUs designed for add-on graphics boards, intended for the high-margin PC gaming market, and later diversification of the product line covered all tiers of the PC graphics market, ranging from cost-sensitive GPUs integrated on motherboards to mainstream add-in retail boards. Most recently, GeForce technology has been introduced into Nvidia's line of embedded application processors, designed for electronic handhelds and mobile handsets. With respect to discrete GPUs, found in add-in graphics-boards, Nvidia's GeForce and AMD's Radeon GPUs are the only remaining competitors in the high-end market.

Voodoo 5
The Voodoo 5 was the last and most powerful graphics card line that was released by 3dfx, 3dfx Interactive. All members of the family were based upon the VSA-100 graphics processor.Lal Shimpi, Anand3dfx Voodoo5 5500 Anandtech, July 11, 2000. Only the single-chip Voodoo 4 4500 and dual-chip Voodoo 5 5500 made it to market. Architecture and performance The VSA-100 graphics chip is a direct descendant of "Avenger", more commonly known as Voodoo3. It was built on a 250 nanometre, nm Semiconductor device fabrication, semiconductor manufacturing process, as with Voodoo3. However, the process was tweaked with a sixth metal layer to allow for better density and speed, and the transistors have a slightly shorter gate length and thinner gate oxide. VSA-100 has a transistor count of roughly 14 million, compared to Voodoo3's ~8 million. The chip has a larger texture cache than its predecessors and the data paths are 32 bits wide rather than 16-bit. Rendering calculations are 40 bits wide in ...

OpenGL
OpenGL (Open Graphics Library) is a Language-independent specification, cross-language, cross-platform application programming interface (API) for rendering 2D computer graphics, 2D and 3D computer graphics, 3D vector graphics. The API is typically used to interact with a graphics processing unit (GPU), to achieve Hardware acceleration, hardware-accelerated Rendering (computer graphics), rendering. Silicon Graphics, Inc. (SGI) began developing OpenGL in 1991 and released it on June 30, 1992. It is used for a variety of applications, including computer-aided design (CAD), video games, scientific visualization, virtual reality, and Flight simulator, flight simulation. Since 2006, OpenGL has been managed by the Non-profit organization, non-profit technology consortium Khronos Group. Design The OpenGL specification describes an abstract application programming interface, application programming interface (API) for drawing 2D and 3D graphics. It is designed to be implemented mostly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphics Pipeline
The computer graphics pipeline, also known as the rendering pipeline, or graphics pipeline, is a framework within computer graphics that outlines the necessary procedures for transforming a three-dimensional (3D) scene into a two-dimensional (2D) representation on a screen. Once a 3D model is generated, the graphics pipeline converts the model into a visually perceivable format on the computer display. Due to the dependence on specific software, hardware configurations, and desired display attributes, a universally applicable graphics pipeline does not exist. Nevertheless, graphics application programming interfaces (APIs), such as Direct3D, OpenGL and Vulkan were developed to standardize common procedures and oversee the graphics pipeline of a given hardware accelerator. These APIs provide an abstraction layer over the underlying hardware, relieving programmers from the need to write code explicitly targeting various graphics hardware accelerators like AMD, Intel, Nvidia, a ...

HyperZ
HyperZ is the brand for a set of processing techniques developed by ATI Technologies and later Advanced Micro Devices and implemented in their Radeon-Graphics processing unit, GPUs. HyperZ was announced in November 2000 and was still available in the TeraScale (microarchitecture), TeraScale-based Radeon HD 2000 Series and in current Graphics Core Next-based graphics products. On the Radeon R100-based cores, Radeon DDR through 7500, where HyperZ debuted, ATI claimed a 20% improvement in overall rendering efficiency. They stated that with HyperZ, Radeon could be said to offer 1.5 gigatexels per second fillrate performance instead of the card's apparent theoretical rate of 1.2 gigatexels. In testing it was shown that HyperZ did indeed offer a tangible performance improvement that allowed the less endowed Radeon to keep up with the less efficient GeForce 2, GeForce 2 GTS. Functionality HyperZ consists of three mechanisms: ; Z compression: The Z-buffer is stored in a lossless compre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hidden Surface Determination
In 3D computer graphics, hidden-surface determination (also known as shown-surface determination, hidden-surface removal (HSR), occlusion culling (OC) or visible-surface determination (VSD)) is the process of identifying what surfaces and parts of surfaces can be seen from a particular viewing angle. A hidden-surface determination algorithm is a solution to the visibility problem, which was one of the first major problems in the field of 3D computer graphics. The process of hidden-surface determination is sometimes called hiding, and such an algorithm is sometimes called a hider. When referring to line rendering it is known as hidden-line removal. Hidden-surface determination is necessary to render a scene correctly, so that one may not view features hidden behind the model itself, allowing only the naturally viewable portion of the graphic to be visible. Background Hidden-surface determination is a process that identifies which surfaces are not visible to the user (for example, ...

Z-buffer
A z-buffer, also known as a depth buffer, is a type of data buffer used in computer graphics to store the depth information of Fragmentation (computing), fragments. The values stored represent the distance to the camera, with 0 being the closest. The encoding scheme may be flipped with the highest number being the value closest to camera. In a Graphics pipeline, 3D-rendering pipeline, when an object is projected on the screen, the depth (z-value) of a generated Fragment (computer graphics), fragment in the projected screen image is compared to the value already stored in the buffer (depth test), and replaces it if the new value is closer. It works in tandem with the rasterizer, which computes the colored values. The fragment output by the rasterizer is saved if it is not overlapped by another fragment. Z-buffering is a technique used in almost all contemporary computers, laptops, and mobile phones for generating 3D computer graphics. The primary use now is for Video game graphic ...
