Abstract:Aiming at the poor training effect problem of ship's air compression training systems are mostly semi-physics simulation software interface with two-dimensional simulation combination be used. Virtual reality technology be used into the compressed air system of ship. Designing compressed air system based on 3D unity, to achieve real-time interactive virtual simulation programs and three-dimensional virtual scene. It can generate a realistic three-dimensional visual, auditory, tactile sensory world, to strengthen the sense of immersion training of personnel, so as to obtain an exposure to the real-world experience. Can be achieved without restrictions on repeated training, saving the entire system maintenance costs, to avoid possible risks in the operation of real equipment, can greatly improve the effectiveness of training.
