Research on urban rapid 3D modeling and application based on CGA rule

Use CityEngine as the 3D modeling platform, research on urban rapid 3D modeling technology based on the CGA(Computer Generated Architectur) rule, solved the problem of the rapid creation of urban 3D model in large scenes, and research on building texture processing and 3D model optimization techniques based on CGA rule, using component modeling method, solved the problem of texture distortion and model redundancy in the traditional fast modeling 3D model, and development of a three-dimensional view and analysis system based on ArcGIS Engine, realization of 3D model query, distance measurement, specific path flight, 3D marking, Scene export, etc
