The Conference on Computing in High Energy and Nuclear Physics (CHEP) serves as a major forum for addressing the software and computing challenges of large-scale experiments in high-energy physics. The 2024 event was jointly hosted by AGH University of Kraków, the Institute of Nuclear Physics Polish Academy of Sciences, and Jagiellonian University.
Held in Kraków, CHEP 2024 continued the conference’s tradition of rotating between the Americas, Asia, and Europe. This year’s edition featured a packed program of scientific sessions, technical contributions, and community engagement.
Our team at the Nuclear Engineering Centre, Georgian Technical University in Tbilisi, Georgia — comprising Alexander Sharmazanashvili, Nino Zurashvili, Vladimir Dolinski, and Mariam Nozadze — presented our work on the development of a browser-based 3D visualization approach for the ATLAS Outreach Applications.
The TRACER framework leverages gaming technologies such as React, TypeScript, and WebGL/Three.js to deliver immersive and interactive visualizations tailored for outreach and education. These include Augmented Reality (AR), Virtual Reality (VR), and Mixed Reality (MR) applications that help make complex detector infrastructure and particle collision events accessible to a wider audience.
Key features of the TRACER suite include:
- Event Displays for visualizing ATLAS detector collisions
- AR/VR modules such as AR Books, AR Doors, and AR Tables
- Optimized performance through local caching and efficient object loaders
- Adaptability to diverse hardware platforms without requiring installations
Our team highlighted the importance of using “as-built” geometry representations, employing performance optimization strategies (e.g., polygon count limits and draw call reductions), and implementing a modular architecture to support scalable educational applications.
This work underscores how modern web technologies can democratize access to complex scientific infrastructures, strengthening the role of visualization in science communication and education.
