Papers session #5: Big, Small, Broad, Deep and Close

13 November 2020 //  by Don Brutzman

Session chair Takeshi Kurata, University of Tokyo, Japan. 5 papers.

Improved methods for applying 3D web-based visualization at various scales is a recurring theme of papers presented in this session of the Web3D 2020 Conference. The first paper proposes a technique for exchanging geometry in manufacturing between Product Lifecycle Management (PLM) applications, which give a global view of product data from design to disposal, with the more detailed data driving and created during production through a Manufacturing Execution System (MES). A second paper dives down to the smallest length scales currently accessible to science, offering X3D-based solutions for making the instruments and results of research into nuclear structure available to scientists and non-specialists, using 3D visualizations delivered in a virtual reality system. Virtual reality is also a topic for the third paper, which presents the results of an empirical study into the effect of exaggerating physical features and gestures of the avatars — representations of human characters — in virtual reality. Planned and deliberate bending of realism in visualization is shown to be potentially useful. The fourth paper again looks to improving the effectiveness of avatars in the practical application of virtual conferencing, through a system architecture which supports multiple interacting avatars. Our fifth paper is an empirical study of the communication effectiveness of enhancing 2D visualizations of large data sets using depth cues, visual features that the human vision sense can use to generate a mental 3D image; without the data requirements that can make a pure 3D visualization unfeasible for large data sets.

Papers session #4: Extending Web3D/VR/XR in Content and Effects

12 November 2020 //  by Don Brutzman

Session chair Kwan-Hee Yoo, Chungbuk National University. 4 papers.
Online at https://web3d.siggraph.org/event/papers-session-4

Web3D provides convenient and pervasive online 3D visualization. While the computing and caching capability of Web browsers lags in comparison to offline 3D platforms, 3D Web content is growing and visual effects are improving. Four papers in this session illustrate these trends.  The first paper presents an unified representation of WebXR content to synthesize real space and virtual space. The second paper explores how to visualize evacuation behaviors of large-scale virtual crowds, an important real-world safety challenge. The third paper enhances rendering effects for scanned 3D data by suppressing shading of the reference model. The fourth paper brings high-fidelity computational sound into X3D scenes through audio graphs and  acoustic properties. Each of these research efforts extend both content capabilities and audiovisual effects of Web3D/WebVR/WebXR.

Papers session #3: CAD Scalability and Realism on the Web

11 November 2020 //  by Don Brutzman

Session chair Christophe MOUTON, Électricité de France (EDF), Paris France.  5 papers.

Online at https://web3d.siggraph.org/event/papers-session-3


Creators of hyperconnected applications for digital twins face a whole set of challenges. Key topics include best use of open neutral CAD data exchange standards for visualization, next-generation rendering of point clouds for CAD data, and even combining the physics of kinematics with physically based rendering in shared Web-based environments. A common need across each domain is whether Semantic Web might “come to the rescue” for querying and exploring difficult-to-reach questions. Speakers share their experiences and results to address each of these challenges, and attendees gain solid foundations to succeed in their own digital twin projects.
