Research on the 3D visualization modeling technique of complex underground Chambers

Establishing the 3D model of complex underground chambers and combining the model with geological 3D model to process the spatial analysis, providing intuitive, effective analysis tools for geological engineering staff is the requirement of visualization of geological engineering analysis. Referring to how to establish the underground chamber model by chamber design silhouette in 3D space, this paper proposes the techniques and methods to establish underground chamber 3D model based on 2D silhouette. These methods are also applied to hydropower engineering, showing that they can quickly and accurately to achieve 3D visualization of underground chambers, providing effective modeling and analysis tools for engineering designer.
