Working Groups

A Working Group of the Web3D Consortium is a technical committee that researches and proposes solutions to specific technical problems relating to X3D (e.g. binary file format).

Working groups are essentially self-forming, self-regulating, and self-directed. They are not product-specific but instead focus is on issues and technologies in the attempt to develop and propagate an open standard for the industry.

Working Groups

The X3D CAD Working Group develops and demonstrates best practices for exporting Computer-Aided Design (CAD) models into X3D to support Web applications.

The Geospatial (X3D-Earth) Working Group uses the Web architecture, XML languages, and open protocols to build a standards-based X3D Earth specification usable by governments, industry, scientists, academia, and the general public.

The H-Anim Working group develops and demonstrates the Humanoid Animation (H-Anim) standard. H-Anim supports a wide variety of articulated figures, including anatomically correct human models, incorporating haptic and kinematic interfaces in order to enable sharable skeletons, bodies and animations.

The Medical Working Group for X3D develops and demonstrates open interoperable standards for the representation of human anatomy based on a wide variety of imaging modalities.

Mixed and Augmented Reality (MAR) capabilities present computer-generated information within the real world, developing compatible extensions to X3D visualization and interactivity that implement an emerging ISO reference model.


The X3D Graphics Working Group addresses all X3D specification issues and coordinates the technical development of future improvements.
