Join the Web3D Consortium for a discussion on how our technology contributes
to the Metaverse. From interactive Real-Time 3D, to Mixed Reality and
Humanoid Animation, everything we do in 3D is significant to an open
Metaverse. See how our members are scaling expertise in 3D, Modeling and
Simulation, Geospatial, Augmented Reality, and Web Audio towards an open,
interoperable Metaverse. Our extensible 3D presentation layer brings 3D
content from different domains from across the WWW into rich, interactive 3D
worlds.

 

b.	ACM SIGGRAPH Cartographic Visualization (Carto) Birds of a Feather

https://s2022.siggraph.org/presentation/?id=bof_101&sess=sess155

The ACM SIGGRAPH Cartographic Visualization (Carto) session explores how
viewpoints and techniques from the computer graphics community can be
effectively applied to cartographic and spatial data sets.  Speakers
demonstrate their latest tools and application efforts.

 

3.	Annual ISO/IEC JTC-1 SC24 meeting - progress report.

 

X3D4, Smart Cities, VR/AR/MAR/XR, virtual/augmented reality health and
safety, more.

 

4.	X3D4 Scene Access Interface (SAI) Review

 

Our "specification mosaic" diagram shows how all the many X3D-related
specifications fit together.

With the X3D4 Draft International Standard (DIS) complete and undergoing
national-body balloting by ISO/IEC, it is time to turn our sights on X3D4
SAI.  This document forms the abstract-API reference and common basis for
numerous other X3D APIs including EcmaScript (JavaScript), Java, Python, C,
C#, C++.

environmental data representation - Extensible 3D (X3D) -
*	Part 2: Scene access interface (SAI) ISO/IEC 19775-2:2015
*	https://www.web3d.org/documents/specifications/19775-2/V3.3
*	X3D is a file format and related access services for describing
interactive 3D objects and worlds. X3D is designed to be used on the
Internet, intranets, and local client systems. X3D is also intended to be a
universal interchange format for integrated 3D graphics and multimedia. X3D
may be used in a variety of application areas such as engineering and
scientific visualization, multimedia presentations, entertainment and
educational titles, web pages, and shared virtual worlds.
*	This part of ISO/IEC 19775 defines the scene access interface that
can be used to interact with X3D worlds both from within the worlds or from
external programs.

 

Based on review/revision of X3D SAI 3.3 in 2015, led by Dick Puk and myself
for Web3D and ISO, this document is pretty mature.  I have performed a
careful document review, available at

Request all interested parties look over this comments review.  Next
go-forward step will be putting X3D4 SAI into Github version control for
Web3D Consortium members.


Thanks for all input and participation.  Have fun with X3D4 SAI review!  8)

 

all the best, Don
