The 3D Modeling of Stratified Geological Objects Based on One-Way Constrained TIN

This paper discusses the current research situation of 3D geological modeling, improves and simplify the previous's 3D geological modeling which include the fault information, according to the feature of mine geological data, and commercial requirements, the modeling principle and geological data of the 3D layered deposits based on surface model was studied, and study of the model visualization method . This paper provides a method of fault treatment based on one-way constrained TIN. Finally, we design and develop system software of the modeling principle of the 3D layered deposits based on the Windows platform, and validation of the model.
