The Application of Viewpoint Follow Technology in Ship Driving Simulation System Base on OSG

For visual simulation with technology development in the difficulty of viewpoint,it analyzed the physical model of matrix calculation principle,motion using OSG(OpenSceneGraph) 3d rendering open-source platform,with ship's navigation system realizes the two first-person roaming effect.It realized with keyboard response events and point of view and completely linkage follow node two visual effects.Mainly introduces viewpoint,this principle with completely linkage with methods closer to the real point of the world,through the results observation,the successful implementation of the first person perspective follow effects,including no waves and the wind conditions,make the technology with viewpoint application scope extend to almost all of the simulation visual roaming program development.
