The field of computer graphics concerned with generating and displaying three-dimensional objects in a two-dimensional space (e.g., the display screen). Whereas pixels in a 2-dimensional graphic have the properties of position, color, and brightness, a 3-D pixels adds a depth property that indicates where the point lies on an imaginary Z-axis. When many 3-D pixels are combined, each with its own depth value, the result is a three-dimensional surface, called a texture. In addition to textures, 3-D graphics also supports multiple objects interacting with one another. For example, a solid object may partially hide an object behind it. Finally, sophisticated 3-D graphics use techniques such as ray tracing to apply realistic shadows to an image.
Converting information about 3-D objects into a bit map that can be displayed is known as rendering, and requires considerable memory and processing power. In the past, 3-D graphics was available only on powerful workstations, but now 3-D graphics accelerator are commonly found in personal computer. The graphics accelerator contains memory and a specialized microprocessor to handle many of the 3-D rendering operations.
- 3-D software
The category of software that represents 3-dimensional objects on a computer. This includes CAD/CAM, computer games, and animation packages.
3ivx is an MPEG-4 toolkit that supports MPEG-4 Video, MPEG-4 Audio and the MP4 file format. 3ivx allows video and audio to be compressed to a fraction of its original size while maintaining high image quality.
- 45 nanometer
45 nanometer (45 nm) is the buzzword of choice (2007-2008) for an advanced semiconductor manufacturing process that Intel used for mass chip production, starting in late 2007. The 45 nanometer manufacturing process uses new materials, including hafnium-based high-k gate dielectrics and metal gates, to reduce electrical current leakage in transistors. Contrast with 90 nanometer.
480p equates to 480 lines of progressive video (480 lines per frame). 480p60 refers to 60 frames per second; 480p30 refers to 30 frames per second; and 480p24 refers to 24 frames per second (film source). Usually refers to 720×480 (or 704×480) resolution.
Short for fourth generation, 4G is an ITU specification that is currently being developed for broadband mobile capabilities. 4G technologies would enable IP-based voice, data and streaming multimedia at higher speeds and offer at least 100 Mbit/s with high mobility and up to 1GBit/s with low mobility (nomadic). 4G is an IP-based and packet-switched evolution […]
