Towards interconnectivity of Metaverses
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The purpose of the 28th International ACM Conference on 3D Web Technology (Web3D 2023) is to study and share the principles and the latest advancements in connected 3D universes. Provide navigation metaphors that allow users to move seamlessly from one virtual world to another.

The goal of the conference and of the Web3D community, which has a rich history of developing technologies that enable the creation, transmission, access, interaction, sharing, and visualization of 3D universes. Bringing together a diverse group of individuals to share innovative and influential thoughts on how the metaverse can revolutionize the future of communications. This includes topics such as 3D applications and services accessible through a wide range of devices, from simple mobile phones to more complex systems such as AR/VR headsets, and heavily populated virtual worlds, especially those connected through high-speed, low-latency networks.

The 28th International ACM Conference on 3D Web Technology (Web3D 2023) is a major event for the Metaverse community. Sponsored by ACM SIGGRAPH, in cooperation with Web3D Consortium and supported by Eurographics, this conference is hosted by Vicomtech and brings together experts from around the world to discuss the latest research, development, and practices related to the Metaverse.

After the initial hype surrounding the Metaverse concept in 2021, many different virtual worlds and platforms emerged where users can interact with each other and virtual objects. To achieve widespread adoption, the Metaverse must overcome several challenges, such as creating realistic virtual environments, improving user-friendly interfaces, ensuring reliable connections between users and metaverses, addressing financial issues such as access costs, and creating stable revenue streams to support growth. Addressing these challenges requires long-term, focused, and consistent solutions.

Presented works will include a wide range of fields including, but not limited to, education, healthcare, e-commerce, informatics, cultural heritage and tourism, entertainment, mass media, military, and construction. The conference welcomes submissions from all relevant domains, as the goal is to create a rich tapestry of ideas on the future of 3D connected universes.

*** Submission ***
https://easychair.org/my/conference?conf=web3d

Note: Full, short paper, and Poster submissions are accepted via EasyChair. If you have a submission in other categories, please send it to program2023@web3d.org. Questions about the program and conference topics can be sent as well to program2023@web3d.org.

The following paper categories are welcome:

* Full or short papers presenting original work in 3D Web research and applications may be submitted in long or short form (up to 9 or 4 pages, EXCLUSIVE of the page(s) devoted to bibliographic references and short appendices). Do include a full citation list. Submissions will be peer-reviewed.

* Posters present results of ongoing or recently completed work in 3D web research and application. The poster format offers the opportunity to interactively present and discuss interesting results to the Web3D community. Posters should be submitted in the form of abstracts (2 pages). Posters must be formatted using the document templates for conferences. Upon acceptance, the final revised poster is required in paper and electronic format. Printing and delivery of the poster is the author's responsibility.

* Tutorials are an opportunity to present introductory and advanced applications of 3D Web technologies to students and to experienced practitioners. Tutorial subjects can include practices for authoring interactive 3D scenes and using 3D graphics in diverse application areas. Especially welcome are tutorials in the use of open-source software and Web applications which can be presented in hands-on sessions at the conference. Submissions should include names, affiliations, and contact information, title of the tutorial, and a short summary including: the topic of interest, subjects covered, learning objectives, intended audience, prerequisites, and level of difficulty.

* Workshops provide a forum for researchers and practitioners from both the Web and 3D multimedia communities to discuss and exchange positions on current and emergent 3D Web topics. Workshops may take the form of presentation sessions moderated by workshop organizers or open discussions of new knowledge on a specific topic of interest. Each session will last 90 minutes with presentations and discussions. Submissions should include names, affiliations, and contact information, title of the workshop, and a short summary including: the topic of the emergent technology and its use cases and challenges.

* Demonstrations enable artists, content designers, and developers to share their innovative 3D work at the conference.
