Abstract

3D modeling techniques have less been established and are still being studied theoretically without explicit implementations. Currently used 3D models, which are primarily focused on visualization and lack topological structure, have limitation in being used for 3D spatial analyses and applications. Through storing 3D objects in a spatial DBMS, we can construct topology-based models and use them for diverse analytical applications. In this study, we use the PostgreSQL/PostGIS for the SDBMS and compare different types of 3D models and suggest suitable ones that satisfy spatial operations and visualization while minimizing computation time. We also visualized the queried geometries using VRML and OpenGL.
