What is X3D?
X3D is a royalty-free open standards file format and run-time architecture to represent and communicate 3D scenes and objects using XML. It is an ISO ratified standard that provides a system for the storage, retrieval and playback of real time graphics content embedded in applications, all within an open architecture to support a wide array of domains and user scenarios.
X3D has a rich set of componentized features that can tailored for use in engineering and scientific visualization, CAD and architecture, medical visualization, training and simulation, multimedia, entertainment, education, and more.
The development of real-time communication of 3D data across all applications and network applications has evolved from its beginnings as the Virtual Reality Modeling Language (VRML) to the considerably more mature and refined X3D standard.
X3D Features at a Glance
- XML Integrated: the key to integration with:
- Web Services
- Distributed Networks
- Cross-platform, inter-application file and data transfer
- Componentized: allows lightweight core 3D runtime delivery engine
- Extensible: allows components to be added to extend functionality for vertical market applications and services
- Profiled: standardized sets of extensions to meet specific application needs
- Evolutionary: easy to update and preserve VRML97 content as X3D
- Broadcast/Embedded Application Ready: from mobile phones to supercomputers
- Real-Time: graphics are high quality, real-time, interactive, and include audio and video as well as 3D data.
- Well-Specified: makes it easier to build conformant, consistent and bug-free implementations
- 3D graphics and programmable shaders - Polygonal geometry, parametric geometry, hierarchical transformations, lighting, materials, multi-pass/multi-stage texture mapping, pixel and vertex shaders, hardware acceleration
- 2D graphics - Spatialized text; 2D vector graphics; 2D/3D compositing
- CAD data - Translation of CAD data to an open format for publishing and interactive media
- Animation - Timers and interpolators to drive continous animations; humanoid animation and morphing
- Spatialized audio and video - Audio-visual sources mapped onto geometry in the scene
- User interaction - Mouse-based picking and dragging; keyboard input
