Simulation of Trajectory Visualization Based on VRML Language

LI Hua,CHEN Wei-wei(1.Naval Ammunition Speciallity Represenative Office in Xi'an,Xi'an 710043,China;2.School of Mechatronics Engineering,North University of China,Taiyuan 030051,China)  
In view of complex animation rendering and difficult modification with 3DMAX software,a new method is put forward.The visualization of a six-degree-of-freedom trajectory simulation is realized with VRML(Virtual Reality Modeling Language) to establish visual scenes and with Simulink to get the result of exterior trajectory equations.The given application software easily displays the exterior trajectory process of the rocket and the simulation scene agrees with the real scene,showing that it can be used for design parameters estimation,demonstration and instruction.
