Research On 3D Military Symbol System And Its Application

Modern war game requests higher and higher fidelity of battlefield situation, but the traditional 2D plotting system is unable to show the 3D situation vividly. Hence, it is necessary to set up a plotting system to match with the modern war game in order to realize the 3D plotting and display of battlefield situation information. But return to have no more complete 3D plotting system at presentThis paper is focused on the research and building-up of a 3D military plotting system and main contents are as followed:1) On the base of the discussion of the similarities and differences between 2D symbol and 3D symbol and related theories, this paper points out that a relatively independent and fixed 3D plotting system should be built, proposes the way of displaying 3D military symbols in details, analyzes the classification of 3D model symbols from viewpoint of making them, and in some degree produces guidance effect on the make of 3D model symbols.2) This paper offers a complete subsystem of 3D vector symbols and a part of the subsystem of 3D symbols, sets up an elementary system of 3D military symbols, and corresponds the 3D symbols with different systems of 2D symbols to realize the 3D military symbols independent of 2D symbols.3) This paper achieves vector symbols and model symbols effectively in different 3D engines, breaks the limit of single 3D engine and makes the 3D military symbols unrelated with the system.The system of military symbols in this paper has already been put into use in some systems. The practical applications all got fine effect.
