摘要: 利用曲面插值方法将用户实际测绘出的地层离散控制点插值成光滑的曲面,进一步获得光滑连续的地质界面的三维地质模型,用于表达各种地质界面。首先介绍几种适合中、小规模数据的常用插值方法,并对比其插值效果,然后介绍基于层次I3样条插值方法,该方法可应用于大规模散乱数据插值中。软件基于Qt和OpenGL进行开发,已经在工程地质中得到很好的应用。

Abstract: 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.
Key words: Three-dimensional modeling, Discrete data, Levels of I3-spline, Surface interpolation, Qt, OpenGL
