A study on 3D modeling techniques and visual system of rock mass structure

Based on the structure characteristics, rock mass can be divided into four kinds of structure elements,including continuous rock mass (unfolded),faultage rock mass (unfolded),folded rock mass and intrusive rock mass,and corresponding spatial data models are built. Pillar Modeling Method, Surface Modeling Method, Single outline Section Modeling Method and Multi-outline Section Modeling Method are developed for building these four kinds of structure elements.A 3D modeling system is developed.
