The document is a glossary template for a games design course assignment, requiring students to research and define video game development terms. It includes terms related to video game testing (e.g. demo, beta, alpha), game engines (e.g. vertex shader, pixel shader, post processing), 3D modeling (e.g. normal map, UV map, procedural texture), physics, and other core concepts (e.g. collision, lighting, animation, sprites). Students must provide a short definition from an online source for each term along with an example of how it applies to their own work.

Salford City College Eccles Sixth Form Centre BTEC Extended Diploma in GAMES DESIGN Unit 73: Sound For Computer Games IG2 Task 1 1 Produce a glossary of terms specific to the methods and principles of Video Game Design and Video Game Terms. Using a provided template, you must research and gather definitions specific to provided glossary terms. Any definitions must be referenced with the URL link of the website you have obtained the definition. You must also, where possible, provide specific details of how researched definitions relate to your own production practice.

Unlike black box testing, white box testing uses specific knowledge of programming code to examine outputs. http://www.webopedia.com/TERM/W/White_Box_Testing.html 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. http://www.answers.com/Q/What_is_the_difference_between_bug_and_glitch GAME ENGINES GAME ENGINES Vertex Shader A Vertex Shader is a GPU component and is also programmed using a specific assembly-like language, like pixel shaders, but are oriented to the scene geometry and can do things like adding cartoony silhouette edges to objects, etc. http://stackoverflow.com/questions/832545/what-are-vertex-and-pixel-shaders Pixel Shader A Pixel Shader is a GPU (Graphic Processing Unit) component that can be programmed to operate on a per pixel basis and take care of stuff like lighting and bump mapping. http://stackoverflow.com/questions/832545/what-are-vertex-and-pixel-shaders Post Processing Post processing allows different effects to be performed on the scene after it has been rendered, but before outputting it to the viewport. http://udn.epicgames.com/Three/PostProcessEffectsHome.html Rendering The processing of an outline image using colour and shading to make it appear solid and three-dimensional http://www.oxforddictionaries.com/definition/english/rendering Normal Map One of the most valuable maps for a 3D artist is the normal map. Rather than having a color range of black to white, like a bump map uses, normal maps consist of red, green, and blue. These RGB values translates to x, y, and z coordinates, allowing a 2D image to represent depth. This way, a 3D application is able to fake lighting details based on the color associated with the 3D coordinate. http://gamedevelopment.tutsplus.com/articles/gamedev-glossary-what-is-a-normal-map--gamedev- 3893 Entity An entity does not need a name or unique identifier it is merely the sum of its components.

This is done by applying a texture map that uses an additional set of coordinates above the classic Cartesian coordinates of X, Y and Z. These 2 new coordinates are titled U and V. So, the title does not refer to UV light but to 2 different coordinates. This makes it possible for the 3d object to
