摘　　要：在3D建模与展示过程中,当目标模型数据量较多时,模型展示的体积会变大,而行业人员可能会更加关注其中某层、区域,或者特定属性范围内的网格分布情况。本文基于Open Inventor的MeshViz和DialogViz扩展模块设计实现一种提取3维模型的切片,和根据属性数据范围筛选模型网格的方案,该方案可以通过交互方式实现数据体的单层提取和感兴趣区域展示,有助于用户分析三维数据体模型的网格分布特性。In the process of 3D modeling and display, when the data amount of the model was large, the visual model would become huge, while the expert may usually pay more attention to the distribution of the grids within some lay- ers, some areas, or some regions with specific attribute range. This article used the MeshViz and DialogViz extended module of the Open Inventor to achieve the method of extracting slices of the 3-dimensional model and the screening model grid based on the scope of the attribute data, the proposed method could extract specific slices and display the ROI region interactively, and could help the user to analyze the characteristics of three-dimensional model more efficiently.
