By Manuel Martin, Mozilla Hubs Engine Team Engineer

Topic of interest: VR/AR/MR/XR, HTML5 3D, WebGL, glTF, Education.

Subjects covered: We will learn how to design and create your own Hubs scene and avatar to host a meeting in a Hubs room. We will also briefly talk about how to extend the Hubs platform using typescript to add your own features to the platform

Learning objectives: The main objective is to introduce the platform, show what’s possible and get familiar with how to set up a Hubs meeting.

Intended audience: Anyone interested in using an open-source web-based platform to create 3D social interactive experiences

Prerequisites: No prerequisites

Level of difficulty: Easy

Scientific Visualization on the Web with VTK and ParaView

Eunate Yaniz — Tue, 18 Jul 2023 10:07:40 +0000

By Jules Bourdais and Julien Finet, Kitware SAS

This tutorial will present the different capabilities and specificities of the open-source libraries and applications such as VTK.js, ITK.wasm, Kitware Glance, VolView and trame. Also, it will explore in a hands-on way how to use trame to enable rapid web application development and prototyping by abstracting away the low-level details by writing only Python code.

Intended audience is two-folds: web developers who want to integrate scientific and medical visualization into their applications, but also research scientists not familiar with web-technologies but with C++ or Python who want to bring their data algorithms and visualizations onto the web. The second part will require basic Python knowledge.

Coordinators: Mike McCann, Vince Marchetti and Doug Sanden

Mike McCann: Undersea robotic vehicle data visualization

Description: From the use case of undersea robotic vehicle data visualization learn how an oceanographer builds a web site to visualize all manner of spatial temporal data using X3D and standard web technology. The tutorial will touch on new features of X3D4 including Point Properties and Volume Data.

Vince Marchetti: Using X3D to visualize knowledge in standards based CAD and BIM files.

Description: We will present techniques for generating dynamic interactive 3D scenes visualizing the contents of vendor-neutral format file from domains of CAD, BIM (Building Information Management), and metrology and inspection. A theme running through the tutorial will be the use of the Python scripting language and the Jupyter notebook platform, to coordinate the activity of open-source libraries to read, analyze, and express in an X3D scenegraph, the domain specific information in STEP, IFC (Industry Foundation Classes), QIF (Quality Information Framework) files.

Doug Sanden: MIDI

Description: Explore ways to integrate MIDI into web3d scenes. Topics covered:

– MIDI 2 transport packets vs MIDI 1 messages

– strategies and conversions for MIDI2 readiness, and MIDI1 back support

– frame speed routing and MIDI-thread direct transport

– Proposed node set, including NoteSplitter, NoteMerger

– javascript MIDI 2 packet parsing and construction

– demo scenes: PlayerPiano, PlayablePiano

– use of midi as an event sequencer for general routing

Spatio-Temporal Digital Twins

Eunate Yaniz — Fri, 16 Jun 2023 09:34:13 +0000

Aims

The Spatio-Temporal Digital Twins workshop aims to bring together researchers and industry practitioners interested in exploring and applying the latest advances in the field. Spatio-temporal digital twins focus on spatial environments at all scales; they rely on the integration of technologies such as spatial AI, Metaverse, 3D modeling, analytics, simulation, and rendering. The workshop also considers their potential applications in various industries, including renewable energy, energy efficiency, mobility, smart cities, Industry 4.0, forestry, and ecological landscapes. The workshop will highlight the impact of AI, metaverse, and sensor technology on building interactive, connected 3D geospatial environments, and provide insights into how these environments can be built in terms of digital twins of real-world environments and provide the foundation for future smart, conscious environments.

Scope

The workshop will provide a platform for researchers to present and discuss their latest research findings, techniques, concepts, methods, and tools related to spatio-temporal digital twins. Topics of interest include, but are not limited to:

Creation and modeling of spatio-temporal digital twins
Data acquisition, processing, and integration for digital twin creation
Visualization and simulation of spatio-temporal digital twins
Interaction and user interfaces for spatio-temporal digital twins
Applications of spatio-temporal digital twins in fields such as renewable energy, forestry, domotics, urban planning, landscape planning, etc.
Performance optimization and scalability of spatio-temporal digital twins
Challenges and future directions for spatio-temporal digital twins

Organizers and Workshop Chairs

Prof. Dr. Jürgen Döllner, University of Potsdam, Hasso-Plattner-Institute, Germany
Prof. Dr. Raffaele de Amicis, Oregon State University, USA
Prof. Dr. Salvador Merino, University of Málaga, Spain

Expectations

We aim to foster an engaging and interactive workshop, promoting discussions and collaborations among attendees. The workshop will include presentations, discussions, and poster sessions, offering a platform to share research findings, work-in-progress, case studies, and industry experiences related to spatio-temporal digital twins.

We hope to attract researchers, industry practitioners, and students interested in geospatial 3D modeling, analysis, simulation, and rendering, as well as their applications in renewable energy, energy efficiency, mobility, smart cities, Industry 4.0, forestry, ecological landscapes, and related fields. This workshop will facilitate networking and collaboration, fostering the development of new ideas and partnerships in the field.

Submissions – 27th July, 2023

We invite original research, work-in-progress, case studies, and industry experiences related to spatio-temporal digital twins. Both short and full papers are welcome.
