基于体数据的三维地质属性体建模

Modeling of 3D Geological Attribute Body Based on Volume Data

文章着重研究采用空间曲面构造三维地质属性体模型。首先,将空间曲面映射到三维体数据中,使用这些具有地质涵义的曲面对体数据进行空间划分,并在体数据中建立三维地质属性体模型。该文提出了一种适合于大数据量的标量体数据表示结构,并基于该结构,提出了一种基于种子填充算法的三维空间区域划分算法。

This Article focuses on modeling of3D geological attribute body by spacial surfaces.Firstly,the surfaces are mapped into geological volume data.And then,the volume data is partitioned according to those curved surfaces.A data structure suits to high-density volume data is proposed.A spacial domain decomposition algorithm based on seed-filling is also proposed in this article.
