Item Integrating Julia Code into the Unity Game Engine to Dive into Aquatic Plant Growth(The Eurographics Association, 2023) Lewerentz, Anne; Manke, Nico; Schantz, David; Sarmento Cabral, Juliano; Mammen, Sebastian von; Pelechano, Nuria; Liarokapis, Fotis; Rohmer, Damien; Asadipour, AliEcologists use process-based ecological models to predict biodiversity, but their complex results can be challenging to com- municate. This challenge can be addressed through interactive visual simulations, which are easy to create with sophisticated game engines such as Unity. However, mechanistic models are increasingly written in the Julia programming language and Unity does not support its integration. In this paper, we present a Julia-Unity plugin that allows direct coupling of Julia and Unity codes. It was developed in a user-centred, iterative manner. The given use case of an immersive, interactive simulation of a macrophyte growth model was tailored to public outreach and science communication. The resulting, rather versatile plugin is a novel tool that features immersive visualisations of Julia-coded simulation models, ecological or otherwise. Due to the features of a game engine, they are particularly apt to engage a wider audience, facilitate collaboration and interdisciplinary work, and enable the exploration of complex systems.Item Investigating Crowdsourced Help Facilities for Enhancing User Guidance(The Eurographics Association, 2023) Babu, Sooraj K.; Brandner, Tobias; Truman, Samuel; Mammen, Sebastian von; Pelechano, Nuria; Liarokapis, Fotis; Rohmer, Damien; Asadipour, AliWe present two help facilities aimed at addressing the challenges faced by users new to a software. Software documentation should ideally familiarise with the overall functionality, navigate through the concrete workflows, and opportunities for customisation. Large degrees of freedom in the use and vast basic scopes, however, often make it infeasible to convey this information upfront. Rather, it needs to be broken into helpful bits and pieces which are delivered at appropriate times. In order to address this challenge, we have designed two concrete help facilities, i.e. tooltips and tips-of-the-day, to feature crowdsourced information. In this paper, we present the results of a formative study to implement early proofs-of-concept for the open-source game authoring platform Godot. To support further research, we have made the code base publicly available on GitHub.Item Programmatic Design and Architecture of an Immersive Laser Laboratory(The Eurographics Association, 2023) Müller, Andreas; Müller, Stefan; Brixner, Tobias; Mammen, Sebastian von; Pelechano, Nuria; Liarokapis, Fotis; Rohmer, Damien; Asadipour, AlifemtoPro provides an immersive laser laboratory experience for training, experimentation and analysis. In this paper, we present its programmatic design and architecture driven by requirements such as: accurate (non-)linear optics calculations, real-time performance on virtual reality (VR) headsets, easy authoring capabilities of pedagogical ''quests'', as well as natural user interactions and effective, multisensory feedback. We elaborate on how we tackle these challenges considering frontend components and the simulation backend. Notable features encompass an incremental, graph-based laser path solver algorithm with caching capabilities, a volumetric pulse shape renderer with accurately mapped color and transparency, an intuitive interaction system that translates coarse hand motions into precise adjustments, a comprehensive interface for configuring, conducting, and analyzing complex experiments with double precision accuracy including time-series measurements with moving platforms, and a generally flexible, modular architecture achieved through event-based communication, dynamic binding, and other state-of-the-art coding principles. Most of our proposed solutions should be directly applicable to similar immersive science laboratories, independently of their concrete domain.
