2.5D Games – Games that use graphics created in 2D graphic software, but where the illusion of 3D is created by using design techniques such as parallax projection and top-down perspective.
3D Modeling - The process of developing 3D assets using a 3D software package.
Aliasing – A 2D graphic that has a jagged edge due to limited number of pixels.
Alignment Game - Players attempt to align up objects and/or arrange objects into specific patterns.
Ambient Light – Light that is scattered from various objects in which no discernable source is
evident.
Antagonist – Is the person or some other force that works against the main character.
Anti-Aliasing - A technique of smoothing out the appearance of the jagged edges by picking colors between the object color and the background and making a smoother transition along those edges by putting those colors at each jagged edge
Art Designer – Person responsible for the visual elements of the game.
Audio Engineer – Person responsible the sounds, musical score, background music and ambient
sounds used in the game.
Backlight – A light located behind the subject which helps separate objects from the
background, giving a more defined space.

calculate the angle of light coming from each light and alters the polygon to become
lighter of darker.

actions assigned.

Open game system – A game environment consisting of a group of players across several games
and many different game sessions.
OpenGL – Free, open source graphic card software used to process graphic information.

fixed point and an angle from a fixed direction. The polar coordinate system is often used in 2D games to define the direction of gravity or missile.
Polygon – a square-shaped plane that consists of at least 4 vertices and two more triangles.
Polygon Count – The actual number of polygons (or triangles) that an object contains. Important
to game design because most graphic cards are rated by the number of polygons per second that can be processed or rendered.
Polygon Culling – The process of eliminating 3D polygons that lie outside the viewer’s

shoot ‘em up games
Serious Games – Games that educate teach or help the player to learn a new skill.
Shadows – The area of darkness created when light does not bend around objects. In the 3D
world, shadows work hand-in-hand with light for an overall effect. Shadows help to
ground objects and prevent the illusion that the object is floating.
Side-Scroller Camera - Shows the world from the side and are more common in 2D games than
3D games.
Social Fun - Games that use storytelling and tap into the human desire for social interaction

the same way as X, Y, and Z coordinate variables describe positions of polygonal vertices.
UVW Unwrapping – The process of removing the default texture of a 3D object to create a 2D
image that can be brought into a 2D graphic package. The graphic artists
can create and develop the 2D texture which will later be reassigned to the 3D object.
UVW Wrapping – The technique of applying a 2D image onto a 3D object. The texture can be
moved or rotated to achieve the correct placement of the texture.
