A digital twin is a virtual representation of a physical object, system, or environment that enables real-time monitoring, simulation, and analysis. In Unreal Engine and pixel streaming platforms like Arcane Mirage, digital twins replicate physical assets or spaces with high fidelity, capturing data from sensors, IoT devices, and simulations to mirror real-world behaviors and conditions. Digital twins are utilized in industries such as manufacturing, healthcare, urban planning, and aerospace to optimize operations, predict outcomes, and facilitate decision-making based on accurate insights and simulations. By integrating digital twins with Unreal Engine's simulation capabilities, developers can create interactive, data-driven experiences that enhance understanding, improve performance, and enable predictive maintenance of assets or environments in virtual and augmented reality scenarios.
