Three-dimensional Geological Modeling Based on Qt and OpenGL
基于Qt和OpenGL的三维地质建模

Surface interpolation method was used to interpolate the actual formation discrete control point maped out by the user into smooth surfaces, so as to further obtain a smooth continuous three-dimensional geological model of the geological interface which can be used to express a variety of geological interface. This paper described several commonly used interpolation methods which are suitable for small-scale data and compared the interpolation results, and then introduced hierarchical I3-spline based interpolation method, which can be applied to large-scale scattered data interpolation. Software is based on Qt and OpenGI_ for development, has been very good in engineering geology applications.
