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] |

3D Computer Graphics
3D computer graphics, or “3D graphics,” sometimes called CGI, 3D-CGI or three-dimensional computer graphics are graphics that use a three-dimensional representation of geometric data (often Cartesian) that is stored in the computer for the purposes of performing calculations and rendering digital images, usually 2D images but sometimes 3D images. The resulting images may be stored for viewing later (possibly as an animation) or displayed in real time. 3D computer graphics, contrary to what the name suggests, are most often displayed on two-dimensional displays. Unlike 3D film and similar techniques, the result is two-dimensional, without visual depth. More often, 3D graphics are being displayed on 3D displays, like in virtual reality systems. 3D graphics stand in contrast to 2D computer graphics which typically use completely different methods and formats for creation and rendering. 3D computer graphics rely on many of the same algorithms as 2D computer vector gr ...

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.

Autodesk Maya
Autodesk Maya, commonly shortened to just Maya ( ), is a 3D computer graphics application that runs on Windows, macOS and Linux, originally developed by Alias and currently owned and developed by Autodesk. It is used to create assets for interactive 3D applications (including video games), animated films, TV series, and visual effects. History Maya was originally an animation product based on code from The Advanced Visualizer by Wavefront Technologies, Thomson Digital Image (TDI) Explore, PowerAnimator by Alias, and ''Alias Sketch!''. The IRIX-based projects were combined and animation features were added; the project codename was Maya. Walt Disney Feature Animation collaborated closely with Maya's development during its production of ''Dinosaur''. Disney requested that the user interface of the application be customizable so that a personalized workflow could be created. This was a particular influence in the open architecture of Maya, and partly responsible for it becoming popul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3D Studio Max
Autodesk 3ds Max, formerly 3D Studio and 3D Studio Max, is a professional 3D computer graphics program for making 3D animations, models, games and images. It is developed and produced by Autodesk Media and Entertainment. It has modeling capabilities and a flexible plugin architecture and must be used on the Microsoft Windows platform.

Triangle Primitives
Computer graphics deals with generating images with the aid of computers. Today, computer graphics is a core technology in digital photography, film, video games, cell phone and computer displays, and many specialized applications. A great deal of specialized hardware and software has been developed, with the displays of most devices being driven by computer graphics hardware. It is a vast and recently developed area of computer science. The phrase was coined in 1960 by computer graphics researchers Verne Hudson and William Fetter of Boeing. It is often abbreviated as CG, or typically in the context of film as computer generated imagery (CGI). The non-artistic aspects of computer graphics are the subject of computer science research. Some topics in computer graphics include user interface design, sprite graphics, rendering, ray tracing, geometry processing, computer animation, vector graphics, 3D modeling, shaders, GPU design, implicit surfaces, visualization, scientific com ...

Vertex Attributes
A vertex (plural vertices) in computer graphics is a data structure that describes certain attributes, like the position of a point in 2D or 3D space, or multiple points on a surface. Application to 3D models 3D models are most often represented as triangulated polyhedra forming a triangle mesh. Non-triangular surfaces can be converted to an array of triangles through tessellation. Attributes from the vertices are typically interpolated across mesh surfaces. Vertex attributes The vertices of triangles are associated not only with spatial position but also with other values used to render the object correctly. Most attributes of a vertex represent vectors in the space to be rendered. These vectors are typically 1 (''x''), 2 (''x, y''), or 3 (''x, y, z'') dimensional and can include a fourth homogeneous coordinate (''w''). These values are given meaning by a material description. In realtime rendering these properties are used by a vertex shader or vertex pipeline. Such attr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C4 Engine
The C4 Engine is a proprietary computer game engine developed by Terathon Software that is used to create 3D games and other types of interactive virtual simulations for PlayStation 5, PlayStation 4, PlayStation 3, Windows ( XP and later), Mac OS X (versions 10.9 and later), Linux, and iOS. Development history Development of the C4 Engine is led by computer graphics author Eric Lengyel, who is also the founder of Terathon Software. Although in development sporadically for several years beforehand, the engine was first made available under a commercial license in May, 2005. Due to changing market conditions, the C4 Engine was retired in 2015, but an announcement has been made that it is returning in 2021. Capabilities and features The architecture of the C4 Engine is that of a layered collection of software components, in which the lowest layers interact with the computer hardware and operating system, and the higher layers provide platform-independent services to the game ...

GlTF
glTF is a standard file format for three-dimensional scenes and models. A glTF file uses one of two possible file extensions: .gltf (JSON/ASCII) or .glb (binary). Both .gltf and .glb files may reference external binary and texture resources. Alternatively, both formats may be self-contained by directly embedding binary data buffers (as base64-encoded strings in .gltf files or as raw byte arrays in .glb files). An open standard developed and maintained by the Khronos Group, it supports 3D model geometry, appearance, scene graph hierarchy, and animation. It is intended to be a streamlined, interoperable format for the delivery of 3D assets, while minimizing file size and runtime processing by apps. As such, its creators have described it as the "JPEG of 3D." Releases glTF 1.0 The file format was conceived in 2012 by members of the COLLADA working group. At SIGGRAPH 2012, Khronos presented a demo of glTF, which was then called WebGL Transmissions Format (WebGL TF). On October 19, ...
