基于MeshViz的动态交互式图例技术研究

Dynamic Interative Legend Based on MeshViz

在三维可视化场景中,图例可以提供数据映射对应颜色范围的直观表示。采用Open Inventor中MeshViz和DialogViz扩展模块实现动态交互式图例,用户可以根据需要动态设定数据对应的颜色映射范围和映射方式。实际应用表明,动态交互式图例技术可以提供3维模型自定义的展示方式和更加直观地理解三维模型结构的方法,因而便于用户直观理解模型的结构和分析模型特性。

In three-dimensional visual scene,the legend could provide visual representation of data mapping corresponding to the color range,this article uses the MeshViz,and DialogViz extended module of the Open Inventor to achieve the interactive legend,the user could dynamically set the color mapping range,and mapping mode by GUI interface,so the interactive legend could provide a customized three-dimensional model and a more intuitive understanding of structure of the data model,help the user analyze the characteristics of three-dimensional model more efficiently.
