Building a 3D geological model from field and subsurface data is a typical task in geological studies involving natural resource study. Constructing volume from surface model is an important step of the whole modeling process. In this paper, we present an efficient and robust approach based on the spatial topology to construct volume from surface model even with non-manifold boundary representation. This algorithm finds the surrounding surface of the volume by traversing the stratigraphic binary tree which indicating the spatial topology relation. Our algorithm meets the demanding requirements of interactive model editing and also can be used at numerical simulation. Results from field data modeling illustrate that the proposal method is effective and efficient.
