| Glossary of Technical Acronyms - by N. Polys Version 1.0 API - Application Programming Interface DOM - The Document Object Model which describes the structure and hierarchy of objects in a web page such as forms, images, links, etc. so they can be manipulated by the browser through scripting. MPEG 4 - A patented binary data format and compression scheme that can be used to stream geometry, animations, and other multimedia. Multi-Texturing - The technique in 3D graphics that provides an explicit description of how multiple texture graphic files are transformed, combined and applied to geometry. This adds a great amount of realism to 3D scenes. These various textures fall under the headings of: light & shadow maps, diffuse texture maps, specular texture maps, and environment maps. In the case of X3D, this means a profile extension of additional nodes for hardware accelerated lighting and rendering. NIST- National Institute for Standards Technology NURBS - öNon-Uniform Rational B-Splines are a mathematical way to describe 3D geometry based on curves rather than polygons. SAI - Script Authoring Interface which is the new script API for X3D which is designed to unify scripting languages for 3D and DOM compatibility. SMIL- Synchronized Multimedia Integration Language which can specify the time-sequencing of audio and video elements in a multimedia presentation as well as place them on the display and link them to other media objects. Real Networks utilizes this technology. SVG - Scalable Vector Graphics in a proposed XML application to describe and manipulate 2D shapes, images, and text on a web page. XHTML - The W3C's effort to refine HTML into strict XML. This tightening of the standard gives developers many more options to deliver valid, multi-tiered content. XSL - Extensible Style Language actually consists of 2 XML applications: document transformation and document formatting which allows authors to convert content between different documents and then |
