| Abstract: | Reconstruction of 3D sections by 2D contour lines is an important technical means in geometric modeling of orebodies. The paper discusses the possible problems（contour correspondence and contour connection）in several kinds of reconstructions and puts forward the algorithm of contour reconstruction that is suitable for modeling of geological body section，section-based 3D geological modeling process，line frame plane model of geological body and corresponding geological block model. |
