Research on Key Techniques of Scene Simulation in Flight Simulation of Aircraft Based on Vega Prime

The frame of flight scene simulation system in aircraft is presented. A new method of realizing two-three dimensional linkage based on OpenGL programme to renden two dimensional window is put forward. The predetection of complicated collision detector is realized by nesting collision detector, and the calculation amount of the system is decreased. The texture is used to replace the particle in order to simulate special effect based on classical particle system principle. The method can save system resources.
