针对三维可视化引擎对战场特效表达和真实感的不足，文中基于图形加速处理器的虚拟战场渲染绘制，分析了图形处理器与中央处理器的差别和可编程的图形流水线的绘制过程，通过底层图形学语言OpenGL、Cg引入特效渲染和绘制技术。实验结果表明：图形加速处理器渲染的战场特效更加逼真，提高了渲染效率，并且实现了通信链路、雷达探测、导弹尾焰、爆炸等虚拟战场特殊效果的可视化。

The programmable vertex shader and fragment shader are the sign of the new generation graphic processing unit .As 3D visualization engine is lack of realistic expression of battlefield special effects ,the difference between GPU and CPU ,the rendering process and advantages of programmable graphics pipeline are analyzed ,and special effects rendering and drawing techniques are introduced with the underlying graphics language OpenGL ,Cg .Finally ,the visualization simulation of the communication links ,radar ,missile plumes ,explosions and other special effects is realized .Virtual battlefield visualization experiments show that the graphics processor rendering gets realistic battlefield effects , stable frame rate and stronger programmability .
