Simulation of Trajectory Visualization Based on VRML Language

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.
