Demo A game demo is a freely distributed demonstration or
preview 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 relevant to my
research because it allow me
to see how a game is running
to al low me to find any
problems with it if there is
any at all wrong with i t also
enables me to make a game
better than before in its
earlier s tages.

Beta Beta is usually a trial version of a game for a company. betas

Alpha A very early version of a software product that may not
conta in all of the features that are planned for the final
vers ion. Typically, software goes through two s tages of
tes ting before it is considered finished. The first s tage, called
alpha testing, is often performed only by users within the
organization developing the software. The second stage,
cal led beta testing, generally involves a limited number of
external users.
http://www.webopedia.com/TERM/A/alpha_version.html
An Alpa is used to see how a
game runs and to see how it
could possibly run better by

of ships, aircraft and other applications with minimal or

White-Box
Testing
White-box testing (also known as clear box testing, glass box
tes ting, transparent box testing, and s tructural testing) is a
method of testing software that tests internal structures or
workings of an application, as opposed to i ts functionality
(i .e. black-box testing). In white-box testing an internal
perspective of the system, as well as programming skills, are
used to design test cases. The tester chooses inputs to
exerci se paths through the code and determine the
appropriate outputs. This is analogous to testing nodes in a
ci rcui t, e.g. in-circuit testing (ICT).

Bug A software bug is an error, flaw, failure, or fault in a
computer program or system that causes it to produce an
incorrect or unexpected result, or to behave in unintended
ways . Most bugs arise from mistakes and errors made by
people in either a program's source code or its design, or in
frameworks and operating systems used by such programs,
and a few are caused by compilers producing incorrect code.
A program that contains a large number of bugs, and/or
bugs that seriously interfere with its functionality, is said to
be buggy.
A bug i s when a problem or
something goes wrong with a
game engine it can cause a
sys tem to freeze or reset this
can be a problem if it keeps
on occurring.

Vertex
Shader
A shader or shader model is a software program that
includes instructions on how the GPU should render certain
images on the screen. Game system requirements may
sometimes list a shader model version that is required such
as Shader Model 3.0. This is simply the shader program that
i s required to play the game. Each version of Microsoft's
Di rectX API supports a shader version. Shader version 3.0 i s
supported in DirectX 9.0c, shader v4.0 i s supported in
Di rectX 10, and so on, so i f a graphics card spec mentions
support for DirectX 10 you can rest assured that it will meet
the shader requirements of a game that may l ist shader
vers ion 4.0 in i t's system requirements.

Pixel Shader From Vertex Shader to Pixel Shader
The output of a vertex shader along with texture maps goes
to an interpolation stage and then to the pixel shader. The
pixel shader is another programmable function that allows
flexibility in shading an individual pixel. Whereas vertex
shaders can be used to completely transform the shape of
an object, pixel shaders are used to change the appearance
of the pixels.
http://encyclopedia2.thefreedictionary.com/pixel+shader
Thi s is what makes everything
in a game more graphically
advanced which means a
game will be clean and clear
so most things will look more
real and just overall better.

Post
Processing
The term post-processing (or postproc for short) is used in
the video/film business for quality-improvement image
processing (specifically digital image processing) methods
used in video playback devices, (such as stand-alone DVD-Video
players), and video players software and transcoding
software. It is also commonly used in real-time 3D rendering
(such as in video games) to add additional effects.
http://en.wikipedia.org/wiki/Video_post-processing
Thi s is where a game collects
data so it can then render
things in real time such as
enti ties and world terrains
fas ter.

Rendering Rendering is the process of generating an image from a 2D
or 3D model (or models in what collectively could be called a
s cene file), by means of computer programs. Also, the
results of such a model can be called a rendering. A s cene
fi l e contains objects in a s trictly defined language or data
s tructure; it would contain geometry, viewpoint, texture,
l ighting, and shading information as a description of the
vi rtual s cene.

Normal Map In 3D computer graphics, normal mapping, or "Dot3 bump
mapping", i s a technique used for faking the lighting of
bumps and dents – an implementation of bump mapping. It
i s 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 model by
generating a normal map from a high polygon model or
height map.
http://en.wikipedia.org/wiki/Normal_mapping
Thi s is when a world is made
to look better by adding
shaders and colour to it
which then makes it look

model) is a data model for describing the data or
information aspects of a business domain or its process
requi rements, in an abstract way that lends i tself to
ul timately being implemented in a database such as a
relational database. The main components of ER models are
enti ties (things) and the relationships that can exist among
them, and databases.

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 i f there is great and varying depth to the
objects being textured. Procedural textures may be 2D or
3D.

Collision Col l ision detection typically refers to the computational
problem of detecting the intersection of two or more
objects. While the topic is most often associated with its use
in video games and other physical s imulations, i t also has
applications in robotics. In addition to determining whether
two objects have collided, collision detection systems may
al so calculate time of impact (TOI), and report a contact
manifold (the s et of intersecting points).[1] Collision
response deals with simulating what happens when a
col l ision is detected (see physics engine, ragdoll physics).
Solving collision detection problems requires extensive use
of concepts from linear algebra and computational
geometry.

use of both artificial light sources like lamps and l ight

Dayl ighting (using windows, skylights, or light shelves) is
sometimes used as the main source of light during daytime
in buildings. This can save energy in place of using artificial
l ighting, which represents a major component of energy
consumption in buildings. Proper l ighting can enhance ta sk

LoD – Level
of Detail
In computer graphics, accounting for level of detail involves
decreasing the complexity of a 3D object representation as it
moves away from the viewer or according to other metrics
such as object importance, viewpoint-relative speed or
pos ition. Level of detail techniques increases the efficiency
of rendering by decreasing the workload on graphics
pipeline s tages, usually vertex transformations. The reduced
vi sual quality of the model is often unnoticed because of the
small effect on object appearance when distant or moving
fas t.
http://en.wikipedia.org/wiki/Level_of_detail
Thi s is when things look
better up-close but good at a
di s tance this i s basically
trying to say that it needs to

Scene A cut s cene or event s cene (sometimes in-game cinematic or
in-game movie) is a sequence in a video game over which
the player has no or only limited control, breaking up the
gameplay and used to advance the plot, strengthen the main
character's development, introduce characters, and provide
background information, atmosphere, dialogue, and clues.
Cut s cenes often feature "on the fly" rendering, using the
gameplay graphics to create s cripted events. Cut scenes can
al so be animated, live action, or pre-rendered computer
graphics streamed from a video file. Pre-made videos used
in video games (either during cut scenes or during the
gameplay i tself) are referred to as "full motion videos" or
"FMVs ". Other cut s cenes can simply just be text interludes
