Real-time creating and protracting of 3D static unit symbols

Creating and protracting of 3D static unit symbols are important content of military visualization system.Moreover goodness or badness of the method of creating and protracting is directly related to the run efficiency and the executive effect of visualization system.Based on the nowadays methods,a method of real-time creating and protracting of 3D static unit symbols is advanced that combines real model and billboard technique.The difficulty of the method is to process the image of GDI real-time creating to unit symbol image of 3D effect by an advanced image processing algorithm,which would be displayed by billboard.The results of experiment suggest that the method makes unit symbols to be created rapidly and impropriate less computer memory space,3D unit symbols have specific tactical significance and intense impact of reality and solid in the application scene,and they satisfy the requirement of practical visualization system better.
