摘要:
为了展示三维模型的内部细节,增强三维可视化浏览的直观性与准确性,需要对三维模型进行剖切处理。 现有的剖切方法是基于平面实现对三维模型进行剖切,在大土木工程行业应用中,由于工程结构复杂,体型布置走向大多非正南正北,很难在三维模型中快速找到合适的平面作为剖切面。 为此,提出了一种基于直线三维模型剖切方法,利用三维轻量化模型,在 React 框架下,采用 WebGL 技术在 HTML5 页面上开发了 Web 端系统,实现了基于轻量化模型的直线剖切方法,适用于大土木工程模型可视化仿真分析。 实践证明,该方法高效、灵活度高、易于实现,能够精确地剖切三维模型,易于达到预期的剖切效果。
Abstract:
In order to show the internal details of 3D model and enhance the intuitiveness and accuracy of 3D visualization browsing,the3D model needs to be sectioned. The existing sectioning method is based on the plane to realize the sectioning of 3D model. In the application of large civil engineering industry,due to the complex engineering structure,most of the body layout is not due to the south and north,it is difficult to quickly find in the 3D model to the appropriate plane as the cutting plane. Therefore,we propose a line based three-dimensional model cutting method,using the three-dimensional lightweight model,under the react framework,using WebGL technology to develop the Web system on HTML5 page,and realize the line cutting method based on lightweight model,which is suitable for largecivil engineering model visual simulation analysis. The practice shows that the proposed method is efficient, flexible and easy to implement. It can accurately cut three-dimensional model and easily achieve the desired cutting effect.
