Studying about the developing method of rendering and broadcasting the large scale terrain

Rendering and broadcasting the large scale terrain on internet is a hot and challenging topic in the Computer Graphics research field. In order to get the ideal terrain rendering, some experts have put forward a couple of good solutions for Level of Detail (LOD) which effectively reduces the quantity of the presented triangles, including the quad-tree algorithm on which this paper is based. Rather than the quad-tree algorithm itself which has been discussed a lot, this paper has elaborated a series of methods used in developing this algorithm during the process of rendering and broadcasting large scale terrain. In this paper, we have discussed these methods in the following sequence: first terrain data preprocessing, then rendering and last broadcasting, in which order the practice will also follow. It has been proved that these methods are quite effective according to the success of the Remote Forest Monitoring System, which is based on them.
