HA2 Game Graphics Now - Task 1 – Technical Glossary
PIXEL;
“a minute area of illumination on a display screen, one of
many from which an image is composed.”
RESOLUTION;
“Refers to the sharpness and clarity of an image. The term
is most often used to describe monitors, printers, and bit-mapped graphic
images. In the case of dot-matrix and laser printers, the resolution indicates
the number of dots per inch. For example, a 300-dpi (dots per inch) printer is
one that is capable of printing 300 distinction dots in a line 1 inch long. This
means it can print 90,000 dots per square inch.”
VECTOR IMAGE;
“Vector graphics is the use of geometrical primitives such
as points, lines, curves, and shapes or polygons—all of which are based on
mathematical expressions—to represent images in computer graphics.[1] Vector
graphics are based on vectors (also called paths or strokes), which lead
through locations called control points or nodes. Each of these points has a
definite position on the x and y axes of the work plane and determines the
direction of the path; further, each path may be assigned a stroke color, shape,
thickness, and fill.[2] These properties don't increase the size of vector
graphics files in a substantial manner, as all information resides in the
document's structure, which describes solely how the vector should be drawn.”
RASTER IMAGE;
“In computer graphics, a raster graphics image, or bitmap,
is a dot matrix data structure representing a generally rectangular grid of
pixels, or points of color, view able via a monitor, paper, or other display
medium. Raster images are stored in image files with varying formats”
FILE FORMATS AND USES
- bmp, png, gif, tiff, jpg, psd, pdf,
eps and ai;
COMPRESSION;
“Data compression is particularly useful in
communications because it enables devices to transmit or store the same amount
of data in fewer bits. There are a variety of data compression techniques, but
only a few have been standardized. The CCITT has defined a standard data
compression technique for transmitting faxes (Group 3 standard) and a
compression standard for data communications through modems (CCITT V.42bis). In
addition, there are file compression formats, such as ARC and ZIP.”
IMAGE CAPTURE DEVICES;
“image capture (image acquisition) The process of obtaining
a digital image from a vision sensor, such as a camera. Usually this entails a
hardware interface known as a frame grabber, which captures single frames of
video, converts the analogue values to digital, and feeds the result into the
computer memory. The conversion process is often accompanied with image
compression.”
OPTIMIZING;
“to write or rewrite (the instructions in a program) so as
to maximize efficiency and speeding retrieval, storage, or execution.”
STORAGE AND ASSET MANAGEMENT;
“Digital asset management (DAM) consists of management tasks
and decisions surrounding the ingestion, annotation, cataloging, storage,
retrieval and distribution of digital assets. Digital photographs, animations,
videos and music exemplify the target areas of media asset management”
