大规模场景可见性判断算法研究

Research on Visibility Determination Algorithm for Large-scale Scenes

大规模复杂场景可见性判断技术主要用于解决复杂场景的低负荷绘制问题,是通过研究场景复杂性和人类视觉感知规律等相关因素的内部联系,实现与场景规模和复杂度无关或弱相关的快速绘制技术。论述了可见性判断算法的分类,在分析已有可见性算法的基础上,总结了现有各算法的优点与不足,并指出未来仍然需要重点研究的若干关键问题。

The visibility determination technique of large-scale and complex scenes is used to solve the problem of low-load rendering of complex scenes. It realizes real-time rendering with no or weak correlation with the scale and complexity of the scene by studying the interior relation between the complexity of the scene and the rule of human visual sensing. The classification of visibility determination algorithm is introduced, then the advantages and disadvantages of the existing algorithms are summarized based on analyzing some typical visibility algorithms in detai/. Finally, some key techniques that need further research efforts are pointed out.
