摘要：On the basis of an in-depth analysis about the characteristics of the commonly used 3D entity model, a new integration model based on octree and TIN-CSG is put forward for the applications in digital mine. In this model, we use octree data structure to represent the underground entities and CSG model to represent the overground entities. And then with the terrain surface nodes generated in the process of octree decomposition and ground contour lines of buildings as constrained conditions, we construct terrain surface model by constrained Delaunay triangulation. Simulation results show that the integration model possesses the merits of octree, CSG and TIN, and can represent 3D spatial entities in digital mine effectively.
