In-depth study and explore dynamic quad tree rendering of large-scale terrain. Investigated the problems  which was urgently to be solved  about quad tree. Studied the features and application of dynamic quad tree algorithm and static quad tree algorithm. Analyze and explore the problems about quad tree construction  data storage that is significant in modeling  removing of the grid back  and elimination of T-type fracture. In this study  an algorithm based on storage array was proposed on the basis of the previous research to eliminate T-type fracture. The results showed that the new algorithm not only enhance the streamline effect  but also increased the rendering speed in the large-scale virtual terrain rendering process. The draw rate was enhanced from 8-10 frames/s up to 20-23 frames/s. 2011 IEEE.
