| Blocky Geological Body Representation with Polyhedron and Its Interactive Modification |
| In the field of geological modeling for solid mineral resources, Chinese scientists invented a technique called "rubber membrane technique" for interactive modeling of the blocky geological body. On the basis of this technique, PandaCAEX, a computer ai-ded exploration system, was developed. As this technique remarkably simplifies geological modeling, users can efficiently construct a blocky geological body of arbitrary shape. However, this method is very complicated and has some shortcomings. This paper presents a method that uses polyhedrons directly to model the blocky geological bodies. The algorithm for editing the method is also given. This method, while preserving the advantages of the "rubber membrane technique", is much simpler and more perfect. Serving as the kernel of a newly revised system, this method proves to be practical. |
