AGP
AGP graphics
(AGP) A bus specification by Intel
which gives low-cost 3D graphics cards faster access to
main memory on personal computers than the usual PCI
bus.
AGP dynamically allocates the PC's normal RAM to store the
screen image and to support texture mapping, z-buffering
and alpha blending.
Intel has built AGP into a chipset for its Pentium II
microprocessor. AGP cards are slightly longer than a PCI
card.
AGP operates at 66 MHz, doubled to 133 MHz, compared with
PCI's 33 Mhz. AGP allows for efficient use of frame buffer
memory, thereby helping 2D graphics performance as well.
AGP provides a coherent memory management design which allows
scattered data in system memory to be read in rapid bursts.
AGP reduces the overall cost of creating high-end graphics
subsystems by using existing system memory.

GIF
GIF89
/gif/, occasionally /jif/ (GIF, GIF
89A) A standard for digitised images compressed with the
LZW algorithm, defined in 1987 by CompuServe (CIS).
Graphics Interchange Format and GIF are service marks of
CompuServe Incorporated. This only affects use of GIF
within Compuserve, and pass-through licensing for software to
access them, it doesn't affect anyone else's use of GIF. It
followed from a 1994 legal action by Unisys against CIS for
violating Unisys's LZW software patent. The CompuServe
Vice President has stated that "CompuServe is committed to
keeping the GIF 89A specification as an open, fully-supported,
non-proprietary specification for the entire on-line community
including the web".

and may be nested.

OpenGL
(OpenGL) A multi-platform software
interface to graphics hardware, supporting rendering and
imaging operations. The OpenGL interface was developed by
Silicon Graphics, who license it to other vendors.
The OpenGL graphics interface consists of several hundred
functions operating on 2D and 3D objects, supporting basic
techniques, such as modelling and smooth shading, and
advanced techniques, such as texture mapping and {motion
blur}. Many operations require a frame buffer. OpenGL is
network-transparent, and a common extension to the {X Window
System} allows an OpenGL client to communicate across a
network with a different vendor's OpenGL server.
OpenGL is based on Silicon Graphics' proprietary IRIS GL.

PNG
/ping/ (PNG) An extensible file format for the
lossless, portable, well-compressed storage of {raster
images}. PNG provides a patent-free replacement for GIF and
can also replace many common uses of TIFF.
Indexed-colour, greyscale and truecolour images are
supported, plus an optional alpha channel. Sample depths
range from 1 to 16 bits.
PNG is designed for on-line viewing applications, such as the
World Wide Web, so it is fully streamable with a
progressive display option. PNG is robust, providing both
full file integrity checking and simple detection of common
transmission errors. Also, PNG can store gamma correction
and chromaticity data for improved colour matching on
heterogeneous platforms.
Filename extension: .png.

(Sometimes called "object-oriented" graphics,
though it's nothing to do with object-oriented programming).
The representation of separate shapes such as lines, polygons
and text, and groups of such objects, as opposed to bitmaps.
The advantage of vector graphics ("drawing") programs over
bitmap ("paint") editors is that multiple overlapping elements
can be manipulated independently without using differenet
layers for each one. It is also easier to render an object at
different sizes and to transform it in other ways without
worrying about image resolution and pixels.
