visibility scale

Studied the current rendering methods of large-scale vegetation, including visibility culling technology, level of detail technique ( LOD), as well as image-based rendering ( IBR) and so on. 5.

研究了当前图形学界在应对大规模植被渲染时所采用的各种主流方法，包括消隐技术，层次细节化技术（LOD）以及基于图像的绘制技术（IBR）等。

According to the information of the visibility for the large-scale scene, the large-scale scene was subdivided by using the method of adaptive subdivision, and the rendering has high efficiency.

在实时渲染全局光照过程中，利用大规模场景的可见性信息进行自适应的细分，使得绘制效率提高。
