Demo A game demo is a f reely distributed demonstration or preview of an upcoming or recently
released video game.
http://en.w ikipedia.org/wiki/Game_demo
When looking for a new video game
to play I am never certain I will enjoy
a game so before purchasing it I like
to look for a demo so I can get a feel
for how the game plays before I buy
it.
Beta Beta is usually a trial version of a game for a company. betas are usually experimental
and of ten have problems w ith them.

Some times a developer isn’t
sure i f anyone would actually
l ike their game so they release it
early in beta. This is good
because like a demo I can find
out i f I l ike i t or not.
Alpha The alpha phase of the release life cycle is the f irst phase to begin sof tware testing.
http://en.wikipedia.org/wiki/Software_release_life_cycle#Alpha
Alpha is a good way for
developers to check if a concept
works or not. Alpha is the bare
minimum for a working game
and i s a good way of checking if
an idea works or not.
Pre-Alpha Pre-alpha refers to all activities performed during the sof tware project before testing.

White-Box
Testing
White-box testing tests internal structures or workings of a program, as opposed to the
functionality exposed to the end-user. In w hite-box testing an internal perspective of the
system, as w ell as programming skills, are used to design test cases. The tester chooses
inputs to exercise paths through the code and determine the appropriate outputs.
http://en.wikipedia.org/wiki/Software_testing#White-Box_testing
Bug In several usages in information technology, a bug or glitch (pronounced GLIHTCH ) is a sudden
break in function or continuity, sometimes of a transient nature, with a varying degree of
seriousness.

Vertex Shader Vertex shaders are run once for each vertex given to the graphics processor. The
purpose is to transform each vertex's 3D position in virtual space to the 2D coordinate at
w hich it appears on the screen.
http://en.wikipedia.org/wiki/Shader#Vertex_shaders
Pixel Shader Pixel shaders, also know n as f ragment shaders, compute colour and other attributes of
each f ragment. The simplest kinds of pixel shaders output one screen pixel as a colour
value; more complex shaders w ith multiple inputs/outputs are also possible.
http://en.wikipedia.org/wiki/Shader#Pixel_shaders
Post Processing The term post-processing (or postproc for short) is used in the video/f ilm 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 sof tware and transcoding sof tware. It is also commonly used in real-time 3D
rendering (such as in video games) to add additional ef fects.
http://en.w ikipedia.org/wiki/Video_post-processing
Rendering 1. Rendering is the process of generating an image f rom a model bymeans of computer
sof tware. Rendering is used in architecture, simulators, video games, movies and
television visual ef fects and design visualization.

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 w ithout using more polygons.
http://en.wikipedia.org/wiki/Normal_mapping
Entity A non-player character (NPC), sometimes know n as a non-person character or non-playable
character, in a game is any character that is not controlled by a player. In
electronic games, this usually means a character controlled by the computer
through artif icial intelligence.

UV Map UV mapping is the 3D modelling process of making a 2D image representation of a 3D
model's surface.
http://en.wikipedia.org/wiki/UV_mapping
Procedural
Texture
Procedural textures are textures that are defined mathematically. They are generally
relatively simple to use, because they don't need to be mapped in a special way - which
doesn't mean that procedural textures can't become very
complex.http://wiki.blender.org/index.php/Doc:2.4/Manual/Textures/Types/Procedural
Physics Computer animation physics or game physics involves the introduction of the law s
of physics into a simulation or game engine, particularly in 3D computer graphics, for the
purpose of making the ef fects appear more real to the observer. Typically, simulation
physics is only a close approximation to real physics, and computation is performed using
discrete values.
http://en.w ikipedia.org/wiki/Game_physics
Phys ics in video games are
almost essential (depending on
the game) and can determine
how you interact with the
envi ronment. Differences in
phys ics in video games can lead
to some pretty interesting
mechanics. My favourite physics

Collision Collision detection typically refers to the computational problem of detecting the
intersection of tw o or more objects.

Lighting Lighting is one of the most important and influential elements in environments. It has
the power to make or break the visuals, theme and atmosphere.

AA – Anti-
Aliasing
In 3D video games, anti-aliasing is a very intense process, requiring a lot of computer
pow er. It basically is rendering the w hole image multiple times, and then blurring the
images together, to smooth out the edges.

LoD – Level of
Detail
In computer graphics, accounting for level of detail involves decreasing the complexity of
a 3D object representation as it moves aw ay f rom the view er or according to other metrics
such as object importance, view point-relative speed or position. Level of detail techniques
increases the ef f iciency of rendering by decreasing the w orkload on graphics
pipeline stages, usually vertex transformations.
http://en.wikipedia.org/wiki/Level_of_detail
Animation Animation in video games refers to how things physically look, which includes
everything from the packaging on a retail video game, to the texture of the skin on
each character, to the graphical user interface, to the way a character rolls her ankle
when she walks.
http://www.gamecareerguide.com/features/413/game_art_and_animation_an_introduction.php
Animation can be very satisfying
in video games. My favourite
animation in video games is a
very s imple animation of
someone in GTA V wearing flip
fops at the beach. The flip flops
are fully animated and even
make a small sound as you walk,
instead of just having the flip
flops stick to the bottom of your
feet.
Sprite In computer graphics, a sprite is a tw o-dimensional image or animation that is integrated
into a larger scene. Initially including just graphical objects handled separately f rom the
memory bitmap of a video display, this now includes various manners of graphical
overlays.
http://en.wikipedia.org/wiki/Sprite_(computer_graphics)
Retro games are loved and
recognised by their 2D 8bi t
spri tes for characters and
objects. It is an easy and simple
way of making an aesthetically
pleasing game that is still used
today.
Scene A scene f ile contains objects in a strictly def ined language or data structure; it w ould
contain geometry, view point, texture, lighting, and shading information as a description of
the virtual scene.
http://en.wikipedia.org/wiki/Rendering_(computer_graphics)
When working with the unreal
game engine, anything I added
to the game or altered was
saved in a s cene.
Library A key decision in game programming is w hich, if any, APIs and libraries to use. Today,
there are numerous libraries available w hich take care of key tasks of game
programming. Some libraries can handle sound processing, input, and graphics
rendering. Some can even handle some AItasks such as pathf inding.
http://en.wikipedia.org/wiki/Game_programming#APIs_and_libraries
UI In video gaming, the HUD (heads-up display) or Status Bar is the method by w hich
information is visually relayed to the player as part of a game's user interface

User interface varies from game
to game depending on the
objective of the game. In GTA V

Frames Frame rate, also know n as f rame f requency and f rames per second (FPS), is
the f requency (rate) at w hich an imaging device produces unique consecutive images
called f rames. The term applies equally w ell to f ilmand video cameras, computer
graphics, and motion capture systems. Frame rate is most of ten expressed in f rames per
second (FPS) and is also expressed in progressive scan monitors as hertz (Hz)
http://en.wikipedia.org/wiki/Frame_rate
Frame rate is very important in
fi rs t person shooters. The more
frames you have the faster the
game will be able to process
information giving your
character a faster reaction time,
not to mention the better you
wi l l be able to see.
Concept Concept document, game proposal, or game plan is a more detailed document than the
pitch document. This includes all the information produced about the game. This includes
the high concept, game's genre, gameplay description, features, setting, story, target
audience, hardw are platforms, estimated schedule, marketing analysis, team
requirements, and risk analysis.

Pathfinding Pathf inding is the method for determining how to get a NPC f rom one point on a map to
another, taking into consideration the terrain, obstacles and possibly "fog of w ar".

Pathfinding can be very
di fferent from game to game
and even character to character.
In GTA V there are citizens
