| 摘 要： | 在虚拟现实中,对于遮挡率很高的场景,大部分面片并不可见,针对这种情形,提出了基于屏幕填充的加速算法,算法对场景中的各面片按从前往后的次序绘制,着重于对可见面的检测,从而避免了对大量不可见面的判断和测试,将其应用于复杂场景的实时绘制,取得了较好的效果。

| Abstract: | In the scenes with high occlusion in virtual environment, most polygons are invisible. In order to deal with this complex case, an accelerating algorithm based on screen filling is developed, in which the polygons in the scenes are rendered in a front to back order. Since the algorithm mainly detects the visible surfaces, so a lot of judgments and tests of invisible surfaces are avoided. This algorithm has been applied in complex scenes and the effect is satisfactory. |
