쎲 MMX – Extended Intel command set used
by 166 MHz and higher Pentium
processors bearing this designation. 57
additional commands accelerate
especially integer operations.
쎲 Multifrequency/multisync monitor –
A monitor that can be operated using
different line frequency ranges and can
adjust itself to different image signals
(resolutions).
쎲 OpenGL – 3D software interface (3D
API). Such as implemented in Windows
NT and optionally obtainable for Windows
95, this is based on Iris GL from Silicon
Graphics and is licensed by Microsoft and
ELSA.
쎲 PCI bus – Abbreviation for peripheral
component interconnect bus. A system of
parallel conductors for transferring data
between individual system components,
especially to expansion cards.
쎲 Page flipping – The image prepared in
the ➞back buffer is displayed.
쎲 Page flipping – With the fast method of
page flipping, only the addresses of the
buffer are exchanged. The slower method
copies the contents of the ➞Back buffer
to the ➞Front buffer.
쎲 Phong shading – ➞ Shading.
쎲 Pixel . A picture element.
쎲 Pixel frequency – Pixel cycle
frequency: The number of drawn pixels
per second in MHz.
쎲 Primitive element – A simple,
polygonal, geometric object, such as a
triangle. In most cases, 3D landscapes are
broken down into triangles.
쎲 RAM – Abbreviation for Random Access
Memory. Main memory and memory
expansion in VRAM or DRAM, depending
on the graphics board.
쎲 RAMDAC – On a graphics board,
RAMDAC is responsible for converting
digital signals into analog signals. VGA
monitors can only process analog signals.
쎲 RealColor – In general, stands for a 15
or 16-bit-per-pixel-wide graphic display
mode (32,768 or 65,536 colors).
쎲 Refresh Rate – Indicates (in Hz) how
often the image on the monitor is rebuilt
per second.
쎲 Rendering – The calculative process for
representing 3D scenery, where position
and color are determined for each point in
space. The depth data are located in the
➞Z buffer while the color and size data
are in the ➞frame buffer.
쎲 Resolution – The number of pixels in
both horizontal and vertical directions (e.g.
640 horizontal x 480 vertical pixels).
쎲 RGB – Color data stored in red/green/
blue format.
쎲 ROM – Abbreviation for Read Only
Memory. Solid state memory that can be
read from only.
쎲 S-video – Or S-VHS. A method of
transferring video data signals, where the
signals for ➞Chrominance and
