Virtual environments is a research concept focusing on the creation and study of interactive digital simulations designed to model complex physical or operational systems, particularly relevant for domains like nuclear physics and engineering. This field investigates the design, implementation, and application of immersive or interactive digital spaces capable of representing phenomena such as nuclear reactions, reactor dynamics, or facility operations. Key characteristics include high-fidelity modeling, user interaction, and data visualization, significant for advancing understanding, facilitating training, and enabling analysis in contexts involving hazardous or intricate processes where real-world experimentation is impractical or costly.
