On March 14 and 16, the subject-level and project-level performance evaluation meeting of "Application Information Platform of Rural Housing Design and Construction Technology" under the national Key research and development Plan "Key Technologies of Rural Housing Design and Construction" was held respectively in Beijing.

Among them, the 14th meeting evaluated the work performance of each research task under the project. As the person in charge of the research task "Lightweight Platform Framework and interface Technology based on GIS/BIM", I attended the meeting and reported the research results, technical innovation and completion of assessment indicators achieved in the four years of the research task. Experts formed a unified opinion after discussion, the six research tasks under the subject all passed the performance acceptance. The meeting on 16th accepted the work results of each subject under the project. Professor Zhao Hongrui, who is in charge of the project, will report on behalf of the project, and I will attend the meeting as the person in charge of the research task. After extensive discussion and inquiry, all subjects under the project passed the performance assessment.

The implementation period of the project "Information Platform for Application of Rural Housing Design and Construction Technology" is 2018-2022. Aiming at the problem of backward information technology application level of rural residential projects, this project developed a series of digital tools in planning, design and construction stage, and finally formed a complete information support platform. The task of "Lightweight platform framework and interface Technology based on GIS/BIM", which I am responsible for, focuses on key technologies such as data management, model visualization and platform development in the subject, which provides the platform framework foundation for the smooth promotion of the subject.

"Three-dimensional Dynamic simulation and visualization Method of Sea Waves" has been awarded the invention patent certificate (patent number: ZL202211436973.0).

The invention discloses a three-dimensional simulation method for sea surface wave motion. Based on the analysis and simulation of the change of the shape and position of the sea surface, the process of wave movement can be divided into two sub-processes: elevation change and horizontal movement. For elevation changes, three-dimensional grids are obtained based on fixed horizontal grids and sea level elevation function mapping, and the direction calculation method of top point method is given to realize smooth surface display of sea waves. For horizontal movement, a color change method based on mapping and moving speed of water quality points is proposed to realize the display of water flow in the horizontal direction. Based on the proposed simulation method, the invention also realizes a three-dimensional wave dynamic simulation device, which consists of five modules, namely horizontal grid generation, three-dimensional vertex management, point method direction calculation, map coordinate updating and result display, which can support the three-dimensional dynamic visualization of sea waves in various forms.

Compared with the existing technology, the invention can be applied to the three-dimensional dynamic simulation and visualization of various types of waves including measured waves, regular waves and random waves, and can support the division of horizontal grids in different ranges, different precision and complex situations. It has good scalability, and provides an efficient, reliable method and convenient tool for the simulation of sea waves. It provides a foundation for the application of information digitization and visualization in Marine industries such as Marine ecological environment, Marine engineering, Marine transportation and so on.

Note: The inventors of the patent also include doctoral students Liu Yi, Academician Zhang Jianmin and Associate Professor Li Binbin.
