Research Of OSG-based Three-dimensional Visualization In Battlefield

With the escalation of modern warfare, the introduce to the war of the integration of air and space power, the commander of the battlefield command and control systems have become increasingly demanding. In order to accurately grasp the front of the battlefield situation information, a variety of new radar, detection tools in use, battlefield information in the form of digital information transmitted to the command center.How better to show the trend of information out so that commanders more intuitive, comprehensive grasp of the development of the battlefield situation, the traditional two-dimensional trend plotting system has been difficult to cope.Information on high-tech warfare put forward higher requirements on command and control system, how to make the advantages of informatization and digitalization show up in the display of control systems, which has become an important subject of current research.Three-dimensional visualization of the situation is the best solution to meet these new demands of battlefield display.Three-dimensional visualization of the battlefield situation as a terminal command system showed a more accurate terrain modeling, simple, timely advantage of the situation to display the image.This paper proposes a three-dimensional visualization based on OSG design that great scene through terrain modeling, multi-window operation, and other special effects scenes showing the process of battlefield vividly demonstrated in front of the commander to achieve situational data description and operably linked to a three-dimensional graphics display.Firstly, the use of visual modeling osgEarth big scene terrain elevation for the global terrain were loaded texture mapping, enhanced three-dimensional terrain display authenticity;secondly designed to showcase the idea of multi-window display, the use of the main window shows the trend process, Eagle eye diagram window displays a broader terrain information,information display window and the model window provides specific formations and platform information; ultimate particle system to create special effects in battlefield scenarios, such as:the missile trails, explosions and other special effects missile. In particular, the use of three-dimensional model and window-view control to add a good demonstration of battlefield information. The visualization system is not only capable of displaying information in front of passing trend, but also can be used as simulation training exercises show support for human-computer interaction commands command of modern high-tech warfare command system provides a strong guarantee, based on battlefield control system provides strong support.
