Introducing a versatile and robust Computer Generated Forces (CGF) platform that enhances synthetic environments with dynamic urban, battlefield, maritime, and aerial interactions. VR-Engage empowers users to embody a variety of roles, whether as a first-person human character, a ground vehicle operator, a gunner, a commander, or as the pilot of either a fixed-wing aircraft or a helicopter. It delivers game-like visual fidelity through a high-performance image generator, ensuring a visually engaging experience. Developed by experts in modeling and simulation, it is tailored for an array of training and simulation initiatives. The platform features sensors that accurately simulate the physics of light across various wavelengths, enabling the representation of electro-optical, night-vision, and infrared capabilities. Additionally, it facilitates applications that allow users to model, visualize, and be actively involved in comprehensive whole-earth multi-domain simulations. This innovative tool offers multi-domain computer-generated forces and serves as a multi-role virtual simulator. With its advanced imaging capabilities, including EO, IR, and NVG sensors, it supports synthetic aperture radar simulations, making it an invaluable asset for modern training environments. By integrating cutting-edge technology and realistic simulations, VR-Engage transforms the landscape of virtual training and operational readiness.
