According to the requirements of three field simulation flat for weapons and equipments, design the visual data collection, management and three dimensional environment display system based on man-machine interaction. It layouts the architecture of this system, classifies and manage the collected data of weapons and equipments. Based on OSG technology, it is realized the display of static details and the effect of contextual roaming of weapons and equipments by reading three-dimensional model data. The result of experiment shows that the system integrates interaction with reality. Moreover, it greatly saves the time and the amount of labor which are directly based on Programming Languages for Graphics and the development.
