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.

Beta Computers. A quality-control technique in which hardware or software is
subjected to trial in the environment for which it was designed, usually
after debugging by the manufacturer and immediately prior to marketing.
http://dictionary.reference.com/browse/beta+test
It is a label given to
games which are not
finished but in a playable
development phase so
you can catalogue your
different versions under
even more category’s so
you find your latest

Alpha An early test of new or updated software or hardware conducted by the
developers or manufacturers prior to beta-testing by potential users.
http://dictionary.reference.com/browse/alpha%20test
It is also a label giving to
games which describes a

stage because pre alpha
is normally the
dysfunctional stage
where it is just being

becomes the first stage
where they can test a
stable version of the
actual gameplay
Pre-Alpha A development status given to a program or application that is usually not
feature complete, and is not usually released to the public. Developers are
usually still deciding on what features the program should have at this
status. This status comes before the alpha version, and is the first status
given to a program.
http://en.wiktionary.org/wiki/pre-alpha_version
Its normally the stage
where the game has
come of out of the design

Debug Debugging is the routine process of locating and removing computer
program bugs, errors or abnormalities, which is methodically handled by
software programmers via debugging tools. Debugging checks, detects and
corrects errors or bugs to allow proper program operation according to set
specifications. Also known as debug.
http://www.techopedia.com/definition/16373/debugging
Debugging allows you to
refine your game into the
smoothest experience
you want it to be and
possibly find game
breaking bugs which will
seriously hinder selling of
the product
Automation automatically controlled operation of an apparatus, process, or system by
mechanical or electronic devices that take the place of human labour

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.
http://www.webopedia.com/TERM/W/White_Box_Testing.html
This allows you to break
the game to see how it
responds so if certain
problems only happen if
you mess around with the

Bug A software bug is an error, flaw, mistake, failure, or fault in a computer
program that prevents it from behaving as intended (e.g., producing an
incorrect or unexpected result). Most bugs arise from mistakes and errors
made by people in either a program's source code or its design, and a few
are caused by compilers producing incorrect code Almost the same... It is
generally used like this is a bug that is something that a player can abuse
to improve his in-game resources, or make a game easier and simpler to

ENGINES
Vertex
Shader
A programmable function in display adapters that offers 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 colour, texture, position and direction from the original colour
space to the display space. It allows the original objects to be distorted or
reshaped in any manner.
http://www.pcmag.com/encyclopedia/term/53754/vertex-shader
This allows for us to be

Pixel
Shader
Pixel shaders are tiny programs that can do operations on a single pixel on
the screen, as opposed to geometry shaders and vertex shaders which
work on the geometrical primitives (triangles) that make up everything
you see on the screen. The most common use for pixel shaders is
'shading', approximation to real world lighting. Commonly used shading
model is Phong.
Pixel shaders are executed on your video card, so your video card needs to
support them. Each new version provides more capabilities, so an older
video card will not run newer shaders. A new version of the pixel Shader
specification (e.g. Pixel Shader 3.0) is usually released for each new version
of DirectX (more accurately, Direct3D).
http://gaming.stackexchange.com/questions/22286/what-is-a-pixel-shader

Post
Processing
The term post-processing (or post process 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

Rendering Rendering is the process of generating an image from a model by means of
computer software. Rendering is used in architecture, simulators, video
games, movies and television visual effects and design visualization.
Rendering, the last step in an animation process, gives the final
appearance to the models and animation with visual effects such as
shading, texture-mapping, shadows, reflections and motion blurs.
Autodesk develops industry-specific software with rendering capabilities.
Many rendering programs by Autodesk can be processed and output to a
digital image or raster graphics image file.

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 model by generating a normal
map from a high polygon model or height map.
Normal maps are commonly stored as regular RGB images where the RGB
components correspond to the X, Y, and Z coordinates, respectively, of the
surface normal.
http://en.wikipedia.org/wiki/Normal_mapping
This is way to create
more realistic impacts of
bumps and dents by
using lighting and

Entity An entity is something that exists in itself, actually or hypothetically. It
need not be of material existence. In particular, abstractions and legal
fictions are usually regarded as entities. In general, there is also no
presumption that an entity is animate.
Sometimes, the word entity is used in a general sense of a being, whether
or not the referent has material existence, e.g., is often referred to as an
entity with no corporeal form (non-physical entity), such as a language. It
is also often used to refer to ghosts and other spirits.
The word entitative is the adjective form of the noun entity. Something
that is entitative is "considered as pure entity; abstracted from all
circumstances", that is, regarded as entity alone, apart from attendant
circumstances
http://en.wikipedia.org/wiki/Entity
An entity is what going to
make up most of the
games content because
say you pick up a gun
which is an entity if entity
was not there everything
would not be interactive
it would set movie set in

UV Map This process projects a texture map onto a 3D object. The letters "U" and
"V" denote the axes of the 2D texture [note 1] because "X", "Y" and "Z" are
already used to denote the axes of the 3D object in model space.
UV texturing permits polygons that make up a 3D object to be painted
with colour from an image. The image is called a UV texture map, [1] but
it's just an ordinary image. The UV mapping process involves assigning
pixels in the image to surface mappings on the polygon, usually done by
"programmatically" copying a triangle shaped piece of the image map and
pasting it onto a triangle on the object. [2] UV is the alternative to XY, it
only maps into a texture space rather than into the geometric space of the
object. But the rendering computation uses the UV texture coordinates to
determine how to paint the three-dimensional surface.
http://en.wikipedia.org/wiki/UV_mapping
The uv map is
programming colours or
textures onto a 3d object
and used to take certain
colour made by other
people their images and
then assign that to your
texture

Procedural
Texture
Procedural texture is a computer-generated image created using an
algorithm intended to create a realistic representation of natural elements
such as wood, marble, granite, metal, stone, and others. Usually, the
natural look of the rendered result is achieved by the usage of fractal noise
and turbulence functions. These functions are used as a numerical
representation of the “randomness” found in nature
http://en.wikipedia.org/wiki/Procedural_texture
This is a computer
generated image which
creates realistic
Representation of natural

Physics Computer animation physics or game physics involves the introduction of
the laws of physics into a simulation or game engine, particularly in 3D
computer graphics, for the purpose of making the effects appear more
real to the observer. Typically, simulation physics is only a close
approximation to real physics, and computation is performed using
discrete values.
There are several elements that form components of simulation physics
including the physics engine, program code that is used to simulate
Newtonian physics within the environment, and collision detection, used
to solve the problem of determining when any two or more physical
objects in the environment cross each other's path.

Collision Collision 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
simulations, it also has applications in robotics. In addition to determining
whether two objects have collided, collision detection systems may also
calculate time of impact (TOI), and report a contact manifold (the set of
intersecting points).[1] Collision response deals with simulating what
happens when a collision is detected (see physics engine, ragdoll physics).
Solving collision detection problems requires extensive use of concepts
from linear algebra and computational geometry.

as hit boxes I used mainly

Lighting Introducing lighting into your game is potentially a step towards realism. In
OpenGL you can introduce multiple light sources that are either static or
dynamic. You have a large amount of control over the characteristics of
the light sources at the expense of speed. It is important to realise that a
scene can still have the effects of lighting without a light source. More
about this at a later stage.

all games they can be

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.

LoD – Level
of Detail
Level of detail is a general design term for video game landscapes in which
closer objects are rendered with more polygons than objects that are
farther away. Generally speaking, the level of detail is dictated by the
game's system requirements. Given the power of modern processors, very
little degradation in the level of detail is noticeable anymore.
http://www.techopedia.com/definition/11791/level-of-detail-lod
Level of detail is used in

Animation Computer animation, or CGI animation, is the process used for generating
animated images by using computer graphics. The more general term
computer-generated imagery encompasses both static scenes and
dynamic images while computer animation only refers to moving images.
Modern computer animation usually uses 3D computer graphics, although
2D computer graphics are still used for stylistic, low bandwidth, and faster
real-time renderings. Sometimes, the target of the animation is the
computer itself, but sometimes the target is another medium, such as film.
Computer animation is essentially a digital successor to the stop motion
techniques used in traditional animation with 3D models and frame-by-frame
animation of 2D illustrations. Computer-generated animations are
more controllable than other more physically based processes, such as
constructing miniatures for effects shots or hiring extras for crowd scenes,
and because it allows the creation of images that would not be feasible
using any other technology. It can also allow a single graphic artist to
produce such content without the use of actors, expensive set pieces, or
props.
http://en.wikipedia.org/wiki/Computer_animation
Animation is a way to
move still objects created
in a computer design
software it always used in
game to move the
character which has been
created by a design team
and it always put in
games and is needed for
a successful creation of a

Sprite A computer graphics, a sprite (also known by other names; see Synonyms
below) is a two-dimensional image or animation that is integrated into a
larger scene. Initially including just graphical objects handled separately
from the memory bitmap of a video display, this now includes various
manners of graphical overlays. Originally, sprites were a method of
integrating unrelated bitmaps so that they appeared to be part of the
normal bitmap on a screen, such as creating an animated character that
can be moved on a screen without altering the data defining the overall
screen. Such sprites can be created by either electronic circuitry or
software. In circuitry, a hardware sprite is a hardware construct that
employs custom DMA channels to integrate visual elements with the main
screen in that it super-imposes two discrete video sources. Software can
simulate this through specialized rendering methods.
More recently, CSS sprites are used in web design as a way to improve
performance by combining numerous small images or icons into a larger
image called a sprite sheet or tile set, and selecting which icon to show on
the rendered page using Cascading Style Sheets. As three-dimensional
graphics became more prevalent, sprites came to include flat images
seamlessly integrated into complicated three-dimensional scenes.

Scene A cut scene is a short cinematic clip in a video game to describe a
circumstance the character is involved in, also used for entertainment
purposes or no real purpose at all. Girls enjoy cut scenes because they are
visually stimulating and help to explain the plot of the game. Guys usually
prefer to skip cut scenes even though they can contain useful hints and
tips towards completing levels and earning special achievements

UI The user interface, in the industrial design field of human–machine
interaction, is the space where interactions between humans and
machines occur. The goal of this interaction is effective operation and
control of the machine on the user's end, and feedback from the machine,
which aids the operator in making operational decisions. Examples of this
broad concept of user interfaces include the interactive aspects of
computer operating systems, hand tools, heavy machinery operator
controls, and process controls. The design considerations applicable when
creating user interfaces are related to or involve such disciplines as
ergonomics and psychology. Generally, the goal of human-machine
interaction engineering is to produce a user interface which makes it easy
self-exploratory efficient and enjoyable user friendly to operate a machine
in the way which produces the desired result. This generally means that
the operator needs to provide minimal input to achieve the desired
output, and also that the machine minimizes undesired outputs to the
human.

you need to have to make
