Research on Modeling and Visualization Method of Geological Objects Based on VRML

Geological strata conditions is restriction to the design and construction of projects .The significance of three-dimensional modeling of engineering rock mass is obviously for both construction and monitoring.However,the existing three-dimensional modeling methods have the disadvantages of low productivity and huge amounts of data . Focusing on these problems, a fast modelling method used to build geological model is presented in this paper. Compared with the special geological 3D modeling and analysis software ,VRML has many merits such as flexible visualization method, good transplantation of the visualization achievements , and independent platform . VRML also has the feasibility of low-bandwidth and the real-time visualization and browsing of the models .It is well suited to the visualization requirement of drilling data and cross-sectional data ,and provides a new solution for the realization of the geological visualization.
