This paper proposes an optimization method of thread mode for OSG/Qt framework and a generating algorithm for military standard symbol display using off-screen render to texture technology based on frame buffer object, to improve the display efficiency and human-computer interaction of three-dimensional battlefield situation display and plotting. The basic concept of battlefield situation information was summarized, and the military demand of display and plotting and OSG/Qt architecture were analyzed. On this basis, the software module of three-dimensional battlefield situation display and plotting was designed and tested to verify the plotting efficiency and the human-computer interactiveness of the solution and key technology.
