3-D Geological Modeling of Complicated Underground Engineering by B-Rep and NURBS

Abstract:

In order to obtain 3-D geological modeling and visualization of complicated underground engineering, a 3-D geological visualization modeling based on data structures of B-Rep and NURBS is proposed. Through comprehensive analysis of common data structure for describing the space topology in the field of computer graphics, rapid establishment of accurate topological relation of 3-D geological models for underground engineering in complicated geological conditions and cavern groups is achieved. And the high-quality geometrical data and topological relation information for the geological visualization of slope engineering are provided. By taking a large coal mine as an example, the 3-D visualization model with many functional applications based on geological information is given, which provides a basic platform for the realization of 3-D digital management.
