Demo A game demo is a freely
distributed piece of an
upcoming or recently
released video game. Demos
are typically released by the
game's publisher to help
consumers get a feel of the
game before deciding
whether to buy the full
version.

A demo is part of a
game which you are
able to play, and try
the game out before
you buy it.

Beta A beta test refers to the
distribution of pre-release
game software to a select
group of people so that they
can test the game in their
own homes. The beta version
of a game is as close to
perfect as the company can
make it, but any bugs,
glitches or other issues
discovered in beta testing will
usually be addressed before
the game's official release
Link-http://
www.techopedia.com/definiti
on/27136/beta-test-gaming
A beta is where they
launch the game to a
select few people
while it is in alpha
stage and they try
the game out early
to see how it plays
and what need to be
improved.
This is a picture showing that if you pre-order
Destiny you get access to the Beta.

IG2 Task 1

Alpha Alpha software can be
unstable and could cause
crashes or data loss. External
availability of alpha software
is uncommon in proprietary
software. However, open
source software, in
particular, often have
publicly available alpha
versions, often distributed as
the raw source code of the
software. The alpha phase
usually ends with a feature
freeze, indicating that no
more features will be added
to the software. At this time,
the software is said to
be feature complete.
Link-http://
en.wikipedia.org/wiki
/Software_release_life_cycle
Alpha is one of the
last phases of
building the game
which is what they
use to test in when it
is in beta.
This is picture showing you Titanfall been in
closed Alpha Stages.

IG2 Task 1

Pre-Alpha Pre-alpha refers to all
activities performed during
the software project
before testing. These
activities can
include requirements
analysis, software
design, software
development, and unit
testing. In typical open
source development, there
are several types of pre-alpha
versions. Milestone versions
include specific sets of
functions and are released as
soon as the functionality is
complete.
Link-http://
/Software_release_life_cycle
Pre-Alpha means a
game is still being
written and coded
but it is closer to
being finished.

Gold A game has "Gone Gold" when
the final mastercopy has been
produced at the developer
and sent off for replication,
packaging and shipment.
The game is not yet released,
but it will typicallybe around
2-3 weeks (sometimes less)
before it begins appearing
on store shelves and online
pre-orders arriving at
doorsteps. The term itself
comes from the old practice
of recordable CDs being
manufactured with gold film.
Hence the gold colored CD
actually being the source,
with no reference to copies
sold as in the recording
industry

White-Box
Testing
Also known as glass
box, structural, clear
box and open box testing.
A software testing technique
whereby explicit knowledge
of the internal workings of
the item being tested are
used to select the test data.
Unlike black box testing,
white box testing uses
specific knowledge of
programming code to examine
outputs. The test is accurate
only if the tester knows what
the program is supposed to
do. He or she can then see if
the program diverges from its
intended goal. White box
testing does not account for
errors caused by omission,
and all visible code must also
be readable

Vertex Shader A programmable function in
display adapters that offers a
graphics application
programmer flexibility in
rendering an image. The
vertex shader is used to
transform the attributes of
vertices (points of a triangle)
such as color, texture,
position and direction from
the original color space to the
display space. It allows the
original objects to be
distorted or reshaped in any
manner.
Link-
Vertex Shader is
important because it
makes an image or
even an object look a
lot smoother and a
lot more realistic.

Rendering To convert any coded content
to the required format for
display or printing. Although
the term is typically used to
refer to images, it may refer
to any data. For example, an
HTML page, which contains
text and graphics, is said to
be "rendered" when it is
displayed.

Rendering means
generating a 2D
image in to a 3D
model, it also means
how far you can see
in a game and how
good the textures
look at a distance.

Normal Map
In 3D computer
graphics, normal mapping, or
"Dot3 bump mapping", is a
technique used for faking the
lighting of bumps and dents –
an implementation of bump
mapping. It is used to add
details without using
more polygons. A common use
of this technique is to greatly
enhance the appearance and
details of a low polygon
modelby generating a normal
map from a high polygon
model or height map.
Normal Map is an
implemented of
different types of
surface in the map
and is also used for
faking the lighting of
the surfaces in the
game.

Procedural
Texture
An algorithmic way of
describing a texture. Unlike a
bitmapped texture, in which
the texture is represented as
a bitmap, a procedural
texture describes the texture
mathematically. Although not
widely used, this method is
resolution independent and
can create more precise
textures, especially if there is
great and varying depth to
the objects being textured.
Procedural textures may be
2D or 3D.

AA – Anti-
Aliasing
Antialiasing is a way of
smoothing edges. Computer
monitors display pixels, but
real objects have curves and
lines. In order to display these
on a computer monitor, the
edge is often jagged.
Antialiasing helps reduce the
problem by slightly blurring
edges to the point where
jagged lines don't show easily
or at all.

graphics pipelines to increase
the efficiency at which a
scene can be rendered.
Typically used in gaming, an
LOD algorithm decreases the
visual complexity of objects
that are distant from the point-of-
view camera, leaving a
greater percentage of the
GPU available to render
foreground objects and
characters.
LOD is applied by decreasing
geometric and textural
resolution of faraway objects,
and also reducing the
complexity of that object's
material network. The effect is
applied dynamically in
graduated steps, so that an
object's detail will increase as
textures and models,
the higher the LOD
is, the better the
textures look
however, it can
sometimes make the
game run slow or the
fps could drop. Also
the lower the detail
the worst the game
look but it might run
a little bit better
than normal.

Animation Animation is the process of
creating motion and shape
change illusion by means of
the rapid display of a
sequence of static images that
minimally differ from each
other. The illusion—as in
motion pictures in general—is
thought to rely on the phi
phenomenon. Animators are
artists who specialize in the
creation of animation.
Animations can
be recorded on either
analogue media, such as a flip
book, motion picture film,
video tape, or on digital
media, including formats such
as animated GIF, Flash
animationor digital video. To
display it, a digital camera,
computer, or projector are
used.
Animation is a
technique of
photographing
drawings of
characters moving
step by step.

Scene

that arranges the logical and
often (but not necessarily)
Scene is a cut scene
in a game which
looks realistic and
the developers use

IG2 Task 1
18
spatial representation of a
graphical scene. The
definition of a scene graph is
fuzzy because programmers
who implement scene graphs
in applications — and, in
particular, the games industry
— take the basic principles
and adapt these to suit
particular applications. This
means there is no consensus
as to what a scene graph
should be.
A scene graph is a collection
of nodes in
a graph or tree structure. A
tree node (in the overall tree
structure of the scene graph)
may have many children but
often only a single parent, with
the effect of a parent applied
to all its child nodes; an
operation performed on a
group automatically
propagates its effect to all of
motion capture suits
and equipment to
create these scenes.
Real people move in
the motion capture
suit and it is
recorded and then it
is used in the game.

its members. In many
programs, associating a
geometrical transformation
matrix (see
also transformation and matrix
) at each group level and
concatenating such matrices
together is an efficient and
natural way to process such
operations. A common
feature, for instance, is the
ability to group related
shapes/objects into a
compound object that can
then be moved, transformed,
selected, etc. as easily as a
single object.
It also happens that in some
scene graphs, a node can
have a relation to any node
including itself, or at least an
extension that refers to
another node (for
instance Pixar's PhotoRealisti
c Render Man because of its

Frames Frame rate, also known
as frame
frequency and frames per
second (FPS), is
the frequency (rate) at which
an imaging device produces
unique consecutive images
called frames. The term
applies equally well
to film and videocameras, com
puter graphics, and motion
capture systems. Frame rate
is most often expressed in
frames per second (FPS) and
is also expressed
in progressive scan monitors
as hertz (Hz).
Link-http://

me_rate
Frames or FPS means
how smooth your
game is running and
how many frames it
is using, the more
frames the better
