Visualization Of Efficient Utilization Of Rainwater Resources In Loess Plateau

The efficient use of rainwater resources in the Loess Plateau is very important to the high-quality development of the Loess Plateau.At present,most of the relevant data and results of the efficient use of rainwater resources in the Loess Plateau are in the form of text and pictures,which cannot directly show the collection and utilization process of rainwater resources.The researchers brought some troubles.As a novel multi-dimensional information transmission medium,virtual reality technology is widely used in military,medical,education,industry,transportation and other fields.Through the investigation and analysis of the rainwater utilization process in the Loess Plateau,the functional requirements of the virtual scene for the efficient utilization of rainwater resources in the Loess Plateau are clarified,and the virtual reality technology is used to construct the efficient utilization of rainwater resources in the Loess Plateau,allowing researchers Produce an immersive feeling.The main work is as follows:Through the demand analysis of the rainwater utilization process in the Loess Plateau,this paper clarifies the three-dimensional scene and the functions to be realized in the virtual scene of the efficient utilization of rainwater in the Loess Plateau.The main work is as follows:(1)Simulation of slope water flow effect based on smooth particle hydrodynamics.The smoothed particle hydrodynamics(SPH)method is used to simulate the physical movement process of the slope fluid particles,and the method based on the reaction force between the particles and the grid is used to deal with the solid-liquid boundary problem in the fluid-solid interaction.The screen space rendering method further enhances the realism of the slope water flow.(2)Three-dimensional terrain modeling based on Digital Elevation Model(DEM)data.UAV is used to obtain terrain image data of the demonstration area,and the terrain image data is processed through aerial triangulation and point cloud editing to obtain DEM data and generate 3D terrain of the demonstration area based on DEM data.(3)Model construction in a 3D scene.According to the collected real object information,various models in the scene of the efficient utilization of rainwater resources in the Loess Plateau area are established using three-dimensional modeling software.Through the analysis and calculation of the movement of rain particles,the rainfall effect in the scene is simulated,based on sine waves.And bump mapping technology simulates a realistic river water surface model.(4)Using C# language to write script code,complete the simulation of the process of collecting rainwater resources by the silt dam,and establish a three-dimensional scene to show the efficient use of rainwater resources,including farmland irrigation scenes,industrial water delivery scenes and ecological water use scenes.Through the application of simulation technology,the simulation of the high-efficiency utilization of rainwater resources in the Loess Plateau area has been realized,which can be used as the research results of the team's high-efficiency utilization of water resources in the Loess Plateau,providing reference and reference for related subject research and social practice.
