Forest environment virtual reality navigation system: Implement of the spread of fire in typical terrain

Virtual reality technology is human representation of the outside world, which is revolutionary change not only guarantee a high external validity, but also has high experimental control. fire drills virtual reality technology integrate fluid dynamics, social psychology, multidisciplinary scientific research field which is important in fire safety prevention and relief support, the technical core is to realize the simulation of fire development, an accurate analysis of fire personnel during the injury, gives the best fighting program. The simulation of the fire spreading process is different from totally dependent on computer programs to simulate fire spread. Principal innovation is the combination of 3ds max, Photoshop and VR-platform virtual reality platform to simulate the fire spread, alternative programming of complex computer simulations. This paper studies the basic theory of virtual reality technology knowledge, based on the establishment of three-dimensional model 3ds max full use of VR-platform to create friendly man-machine interaction interface and the ability to write simple code functions, simulate the characteristics of four typical terrain fire spreading process, detailing exploring the process of fire spread simulation methods.
