Fire-fighting Training System Based on Virtual Reality

Applying virtual reality technique to fire-fighting training can effectively solve waste of manpower, material, money and so on. In this paper, we will combine HTC Vive and Unity3D engine to carry out the design and development of fire-fighting training system. Particle system, navigation grid, animation system and collision detection technology are applied to achieve flame flus gas diffusion simulation, non- experiencer follow, animation production, interaction functions between characters and objects respectively, to save time for rendering spent and meet the real-time demand of virtual scenes generation, this paper optimizes virtual scenes by using LOD technology and occlusion culling technique. The results show that the fire-fighting training system has a good sense of immersion, and it can meet the demand of fire-fighting training.
