Abstract
Traditionally, the computer method of delineation requires to establish ore block model. The block-by-section scanning operation is slow, which does not meet the large amount of data calculation., In this paper, we use the ore body in the modeling of the surface model in order to overcome the above problem. This model uses modeling method that reproduces a traditional hand-paintedtechnique, describe the spatial distribution of ore bodies through a series of plan view or profile of the ore body boundary polygon for wireframe modeling, i.e., the frame modeling method. For reading the plan view or profile of the ore body, the graphics and fractal theory are needed in the work to achieve the extraction of vector graphics map elements. After completing the extraction of ore, the wireframe modeling of the ore bodies can be established by using wireframe modeling method. Finally the wireframe model is filled by using the OpenGL technology and the surface model orebody is generated.
