쎲
Buffer swapping –
The image prepared
in the
is displayed.
쎲
Bump mapping –
A technique that pro-
vides textures with depth information,
which can be applied to display relief or
embossed structures.
쎲
Bus system –
A system of parallel con-
ductors for transferring data between indi-
vidual system components, especially to
expansion cards, such as ISA
쎲
Chrominance –
Color information in the
transfer of video signals.
쎲
Clipping –
Reduces the number of
s to be calculated. All primitives
outside the limits of the screen (2D) or out-
side of the
(3D) are
clipped or removed.
쎲
Cube environment mapping –
In order
to represent realistic and undistorted re-
flections of the environment onto an ob-
ject, six
s are viewed as the sur-
faces of a cube. The textures show the en-
vironment from the perspective of the ob-
ject. This gives the impression that the
environment is being reflected by the ob-
ject. CEM is an extension of sphere envi-
ronment mapping. The advantage of CEM
is that no new textures need to be calcu-
lated when the observer's point of view
changes and the texture is not distorted.
쎲
D/A converter –
Digital/analog convert-
er: A signal converter that converts digital
input to analog output.
쎲
DDC –
Abbreviation for Display Data
Channel. A special data channel through
which a DDC-capable monitor can send its
technical data to the graphics board.
쎲
DDR SDRAM –
Double Data Rate
SDRAM is a further development of
memory technology. While
SDRAMs only provide data at the actual
system clock speed, DDR chips permit
data to be accessed at twice the system
clock speed.
쎲
Direct3D –
Software interface (
)
developed by Microsoft for the manipula-
tion and display of 3D content.
쎲
DirectColor –
Method to achieve the
high-resolution
,
and
graphics modes. In
this case, the value stored in the video
RAM (
) is not translated but is
passed directly to the D/A converter
. This means that the full color
information must be saved for each
쎲
DirectDraw –
Software interface (
) developed by Microsoft for the dis-
play of 2D content such as videos.
쎲
Double buffer –
Describes the presence
of doubled display memory. This permits
the next image to be generated first in the
invisible background (
As soon as it is completely constructed,
the monitor display switches to the image
that has been residing in the background
and the preparation of the next image be-
gins on the other side.
