Extracting nodes having the same attribute value in the tunnel geological model to generate an ISO-Surface corresponding to a ground interface;
And generating the geological exploded view from the three-dimensional curved surface of the tunnel lipid model including the iso-surface. 23. The method of claim 21,
Wherein the generating of the tunnel geological model comprises setting an attribute value by performing an interpolator. 23. The method of claim 21,
In the generating of the geological development map, a wall surface, which is a three-dimensional curved surface corresponding to the inner wall surface of the tunnel, is extracted from the tunnel geological model, and then the geological developed map is generated by converting the wall surface into a two- How to construct a three - dimensional visualization model of tunnel information.
