OpenDDL
The Open Data Description Language (OpenDDL) is a generic text-based language that is designed to store arbitrary data in a concise human-readable format. It can be used as a means for easily exchanging information among many programs or simply as a method for storing a program's data in an editable format. The exact syntax of OpenDDL is described on the websitopenddl.orgas well as in an appendix of the ''Open Game Engine Exchange The Open Game Engine Exchange (OpenGEX) format is a text-based file format designed to facilitate the transfer of complex 3D scene data between applications such as modeling tools and game engines.

Open Game Engine Exchange
The Open Game Engine Exchange (OpenGEX) format is a text-based file format designed to facilitate the transfer of complex 3D scene data between applications such as modeling tools and game engines. The OpenGEX format is built upon the data structure concepts defined by the Open Data Description Language (OpenDDL), a generic language for the storage of arbitrary data in human-readable format. The OpenGEX file format is registered with the Internet Assigned Numbers Authority (IANA) as the model/vnd.opengex media type. The OpenGEX format is defined by the ''Open Game Engine Exchange Specification'', which is available on the official websitopengex.org Export plugins that write the OpenGEX format are available for Autodesk Maya and 3D Studio Max. Format At the most basic level, an OpenGEX file consists of a node hierarchy, a set of objects, a set of materials, and some additional information about global units and axis orientation. The various node, object, and material structure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eric Lengyel
Eric Lengyel is a computer scientist specializing in game engine development, computer graphics, and geometric algebra. He holds a Ph.D. in computer science from the University of California, Davis and a master's degree in mathematics from Virginia Tech. Lengyel is an expert in font rendering technology for 3D applications and is the inventor of the Slug font rendering algorithm, which allows glyphs to be rendered directly from outline data on the GPU with full resolution independence. Lengyel is also the inventor of the Transvoxel algorithm, which is used to seamlessly join multiresolution voxel data at boundaries between different levels of detail that have been triangulated with the Marching cubes algorithm. Among his many written contributions to the field of game development, Lengyel is the author of the four-volume book series ''Foundations of Game Engine Development''. The first volume, covering the mathematics of game engines, was published in 2016 and is now known for it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UTF-8
UTF-8 is a variable-width encoding, variable-length character encoding used for electronic communication. Defined by the Unicode Standard, the name is derived from ''Unicode'' (or ''Universal Coded Character Set'') ''Transformation Format 8-bit''. UTF-8 is capable of encoding all 1,112,064 valid character code points in Unicode using one to four one-byte (8-bit) code units. Code points with lower numerical values, which tend to occur more frequently, are encoded using fewer bytes. It was designed for backward compatibility with ASCII: the first 128 characters of Unicode, which correspond one-to-one with ASCII, are encoded using a single byte with the same binary value as ASCII, so that valid ASCII text is valid UTF-8-encoded Unicode as well. UTF-8 was designed as a superior alternative to UTF-1, a proposed variable-length encoding with partial ASCII compatibility which lacked some features including self-synchronizing code, self-synchronization and fully ASCII-compatible handling ...

Base64
In computer programming, Base64 is a group of binary-to-text encoding schemes that represent binary data (more specifically, a sequence of 8-bit bytes) in sequences of 24 bits that can be represented by four 6-bit Base64 digits. Common to all binary-to-text encoding schemes, Base64 is designed to carry data stored in binary formats across channels that only reliably support text content. Base64 is particularly prevalent on the World Wide Web where one of its uses is the ability to embed image files or other binary assets inside textual assets such as HTML and CSS files. Base64 is also widely used for sending e-mail attachments. This is required because SMTP – in its original form – was designed to transport 7-bit ASCII characters only. This encoding causes an overhead of 33–37% (33% by the encoding itself; up to 4% more by the inserted line breaks). Design Each Base64 digit can take on 64 different values, encoding 6 bits of data. Which characters are chosen to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Serialization Formats
In the pursuit of knowledge, data (; ) is a collection of discrete values that convey information, describing quantity, quality, fact, statistics, other basic units of meaning, or simply sequences of symbols that may be further interpreted. A datum is an individual value in a collection of data. Data is usually organized into structures such as tables that provide additional context and meaning, and which may themselves be used as data in larger structures. Data may be used as variables in a computational process. Data may represent abstract ideas or concrete measurements. Data is commonly used in scientific research, economics, and in virtually every other form of human organizational activity. Examples of data sets include price indices (such as consumer price index), unemployment rates, literacy rates, and census data. In this context, data represents the raw facts and figures which can be used in such a manner in order to capture the useful information out of it. Dat ...
