Research on 3D Scene Data Organization and Management Based on Object-Oriented Dynamic Octree

3D scene visualization has a wide range of applications. With the rapid development of various technologies in the corresponding fields, large-scale and complex type of data become a challenge for 3D scene visualization. Existing solutions in 3D visualization platforms are limited in data processing capacity for 3D spatial data and thus difficult to meet the data management requirements of large-scale scenes. Based on the octree partitioning approach, this paper proposed an object-oriented dynamic octree, adjusting the data storage mode, realized dynamic scene scheduling and memory utilization optimization, and improved the rendering efficiency and 3D scene. Based on object-oriented dynamic octree, this research improved the data preprocessing, data dispatch, and data rendering of a self-developed 3D visualization platform and demonstrated that it outperformed other platforms in speed and scale; therefore, it builds a solid base for developing a Chinese graphics engine for construction management platforms.
