| 摘 要： | 分析了在视景仿真应用中,由于普通显卡所支持的Z-Buffer的位数不够,当两个多边形距离很近时,计算机无法区分对应相同屏幕坐标的两个象素点的Z-Buffer的值,从而引起的闪烁现象。并提出了两种解决思路。

| Abstract: | It is presented in this paper the analysis and solutions arising by the Z-Buffer precision. When two polygons are too closer, the computer can not decide which pixel is in the front, which induces flicker. Finally it brings two effective ways to solve the problem and useful advices for building a perfect visual system. |
