3D Scene Simulation of Helicopter Antisubmarine Search Based on Vega Prime

To simulate the process of helicopter antisubmarine search by dipping sonar,model is built to resolve parameters of helicopter's flight track between adjacent hovering spots.Still,Key techniques of developing simulation program of 3D scene are analyzed,such as loading 3D object dynamically,displaying rotary wings,coordinate conversion.Then framework of 3D scene program is presented.Finally,combining VC and Vega Prime software,3D scene program which simulates the process of helicopter antisubmarine search,is developed successfully and the effect is perfect,which is helpful and could provide some reference for developing similar 3D scene program.
