Terrain Visualization Research Based on ModelBuilder and Landscape
3D terrain data is an important digital base element in the construction of digital twins.This paper takes Unreal Engine 5 rendering as an example to propose a 3D terrain model data construction method based on ArcGIS model builder and landscape.This method uses the file organization of the original terrain data to parse the transformation information through the model builder to construct a data reading tree,when iterating over nodes,raster data and image data are converted separately,taking into account the physical properties required by the game engine to render assets,and finally completing the recombination of terrain features and textures.The practical results show that the proposed method can accurately convert the terrain 3D model data to Unreal Engine 5 rendering resources,and can provide theoretical and technical reference for similar 3D model data conversion problems.
