The key techniques of using GL Studio simulate instruments is analyzed in this paper.Combining with VC++6.0,the simulation of a helicopter instrument panel is realized.According to the development process of GL Studio software,the modeling and simulation process of the instrument panel,the methods of setting properties for instruments and the coding process are introduced in detail.The simulation results are shown in this paper.Experiments prove that the GL Studio can create the realistic models.It is a sho...
