Virtual Reality (VR) refers to immersive technology that simulates realistic environments and experiences through head-mounted displays (HMDs), motion tracking, and interactive interfaces. In platforms like Arcane Mirage, VR applications powered by Unreal Engine enable users to interact with 3D environments, objects, and simulations in real-time. Unreal Engine supports VR development with features such as stereoscopic rendering, motion controllers, spatial audio, and VR optimization tools. Developers use Unreal Engine to create VR games, training simulations, architectural walkthroughs, and interactive storytelling experiences that transport users to virtual worlds with high fidelity graphics and responsive interactions. VR applications in Unreal Engine enhance immersion, learning effectiveness, and user engagement across entertainment, education, healthcare, and enterprise sectors.
