摘要
根据图形系统软硬件平台的不同 ,分析了航海模拟器中本船船首图形显示的特点 ,提出了基于 Over-lay、Stencil buffer、Zbuffer和几何绘制四种本船船首图形的绘制方法 .对前三种方法的绘制步骤和纹理源的处理也作了具体的介绍 .用这三种方法绘制的船首图形图像逼真 ,真实感强 ,而且仅需绘制一次 ,大大提高了画面的更新速率 ,可用于图形硬件平台比较低的视景系统中 .
According to the different platforms of visual system in ship handling simulator, the author proposes three methods of drawing ownship's bow image based on overlay, stencil buffer and Z buffer, and drawing bow image only once can be achieved. A more detailed discussion of drawing steps and the processing of texture source is presented as well to generate a simple and efficient approach to render the family of ownship's bow image with its single photograph. All the methods can be applied to lower image hardware platforms to produce more vivid results.
