Abstract:

A threedimensional visual emulation system is developed, which can be used as a training simulator for photoelectric theodolite. The system construction of the training simulator, the formation and showing method of the 3D scene in virtual environment are presented in detail. Visual C++ and OpenGL programming technique are adopted to emulate the target flying scene and show the flying track in real time. Using OpenGL library, this article investigates the modeling technique of the simulation model for the target tracking scene, the skills of producing special effect, the data driving of the model and the change of view point. The visual simulation of flying object is realized and process is controlled by both computer and manipulator. The experimentalist can observe the flying course of the missile and the simulation tracking process by the manipulator from any distance and different angle.

Key words: photoelectric theodolite, training simulator, visual emulation, 3D scene
