Research and Implementation of Tunnel Three-Dimensional Modeling Algorithm Based on Java3d

The paper according to the actual situation of tunnels establishes six models, line tunnel, curve tunnel, link tunnel, vertical tunnel, trigeminal tunnel and binary tunnel based on tunnel midline, designs a general data structure for different section, and the corresponding algorithm of the acquisition for cross-section data of six kinds of model based on the section method. Finally, author implements java3d to program the model algorithm, and realizes the tunnel 3D visualization, and provides a new method for building tunnel 3D model in establishing digital mining 3D visualization platform.
