I
IDE

An Integrated Development Environment. An IDE consists of all the basic tools a programmer needs to create a program. Typically, an IDE consists of a text editor, a compiler, a debugger, and other necessary tools.

IDE (Integrated Drive Electronics) Cable

Not to be confused with, "Integrated Development Environment," this cable connects varius drives to the motherboard allowing data to quickly get from one to the other. It is generally shaped like a ribbon, though round IDE cables do exist.

iDevGames.com

A Macintosh game development site with tutorials, forums, game assets, code and information for Macintosh game developers.

Idle Motion

Idle motions are scripted events that are triggered when the player does not provide any input for a certain period of time. The motions are generally small, like fidgeting, or polishing the weapon.

IDSA

Interactive Digital Software Association. An organization dedicated to improving the business aspects of the industry, often in the areas of piracy and the industry?s image.

IGDA

International Game Developers Association. Community of professional game developers and local game developer chapters. Their website also includes forums, news and information to help the expanding community.

IGDN

The International Game Developers Network. This is group that was created to bring more community to the game industry while also including people from other countries besides the US. (www.igdn.org)

IHV

Independent Hardware Vendor. A hardware manufacturer that specializes in manufacturing a single type of hardware rather than manufacturing full computer systems.

IMHO

In My Humble Opinion.

Independent Developer

A developer that is not owned by a large publishing company.

Independent Games Festival

A competition that promotes independent developers by allowing them to display their games at the Game Developer Conference.

Indexed Color

When color information is stored in a look up table that contains the colors red, green and blue information.

Indot

Indot refers to non-quad and non-tri polygons. For instance a pentegon without triangulation or quads. (This is only appreant during modeling in a 3d application that supports this feature.)

Infinate Power

Infinate Power is a game development group based out of Alberta, Canada. There focus genre(s) are: R.P.G.?s Fantasy, Action, and Adventure. For More information go to http://www.geocities.com/SiliconValley/Monitor/9250

Infinit Loop

This is a condition when a cycle does not terminate. In programming, infinit loops are caused when the termination condition cannot be meet due to a coding error. The following are infinit loops would include: // No termination condition for(;;) { // No termination, has nothing to stop the loop } // Unreachable termination condition for( int i = 0; i != -1; i++) { } // Constant true condition while(1) { } // Incorrect use of operators while(i = 4) { } The above are just a few conditions that will cause an infinite loop.

Initialize

When you initialize a variable, you give it its value. Used in programming. You can define and initialize a variable in one statement to help reduce code size. C++ Example: int num=3; value | variable name type

Instanciate

To make a instance of a class. To create a object.
See Also:C++, Object Oriented Designing

Integer

An integer is a whole number, positive or negative commonly stored as a group of bytes. The integer size usually is in proportion to the pipelining capabilities of the processor architecture it is implemented in. On modern x86 architectures, integers are normally 32-bits in length.

Intellectual Property

The art, sound, music, code, 3d models, design, story, and the like created during game production that make the product what it is. Typically, IP can be copyrighted, trademarked, or patented.

Interface

The means by which an entity interacts with something. In programming, an interface is often used to provide abstraction of functions. The interface defines what methods that a function or class MUST possess. This allows the simple replacement of functions with any other function which also meets the requirments, without requiring any modification elsewhere in the program (particular useful when porting to a different platform, or using an alternate rendering system, etc).

Interlacing

Because the electron guns that draw pictures on TV screens were initially too slow to draw the screen in one pass, the first lines at the top of the screen would be fading by the time the last lines were drawn, pictures on TVs were drawn using what is known as interlacing. First the odd lines down are drawn (line 1, 3, 5, etc.). Then the even lines are drawn (line 2, 4, 6, etc.). The image shown by one pass is known as a field, and the complete image drawn by two passes is known as a frame. Standard TV broadcasts run at 30 frames per second (fps). In an effort to boost hype for a product, sometimes ads or press releases would state that their game was "60 fields per second", instead of 30 fps. Most computer monitors are non-interlaced as well as many arcade screens.

Interpolation

An approximation between two known values. In graphics, this is a process in which the software increases the resolution of an image by first filling the image with blank pixels and then coloring the blank ones based on the color values of its surrounding pixels.

Interpolation

Using a ratio to step gradually a variable from one value to another.

Interpreter

A program that executes programs. Different from a compiler which turns a source code into an executable, the interperter will run interpret-compile each command while running.

Interrupt

1. aka Hardware Interrupts: A request for attention from the processor. When the processor receives an interrupt, it suspends its current operations, saves the status of its work, and transfers control to a special routine known as an interrupt handler, which contains the instructions for dealing with the particular situation that caused the interrupt. ex: int 0x09 - keyboard interrupt 2. aka Software interrupts: functions stored in memory by the operating system to be used by programs to facilitate different tasks (aka system calls). ex: int 0x21 in MS-DOS

Intro Sequence

Generally an intro is a fully animated sequence that appears when a game is first loaded and explains the back-story of the game and may introduce the main character and nemesis.

Inverse Kinematics (IK)

The process of creating realistic positioning of a complex object, such as an arm, based on the positioning of a lower-level node in the skeletal heirarchy, such as the twisting of a hand. This process works in the reverse of forward kinematics.

IP

Intellectual Property

IP

Internet Protocol

IPX

Internetwork Packet Exchange. An unreliable (datagram) protocol introduced by Novell Netware. Complimentary protocol would be SPX.

IRC

Internet Relay Chat. A client-server created to allow people to talk to each over a network. The unit runs a IRC client, such as mIRC, and connects to an IRC server and can then talk to other through channels or directly.

Isometric Tiles

One way of drawing 2D tiles so that it appears that they look 3D as they are layered with depth. In computer games this is usually a misnomer as isometric means a 1-1-1 perspective. Normally in games the depth ratio is less so that the tiles do not seem as wide.
