Scene Graph based Multi-thread Rendering System

Traditional three dimensional system data structure such as tree and linked list does not fit the huge data organization and management. In this paper, we introduced advantage of scene graph data structure in three dimension data management and presented a scene graph based data structure to improve the management and rendering efficiency. To assure high performance in a usual PC machine, we designed a multi-thread structure to respectively handing data reading, merging and rendering. From the experiment, we proved the capability of the multi-thread rendering system in different level of data size.
