Urban macroscopic scene three-dimensional visualization platform system

Abstract

The invention provides an urban macroscopic scene three-dimensional visualization platform system. The urban macroscopic scene three-dimensional visualization platform system comprises a resource loading module, a resource unloading module, a scene optimization module and a UI module; a powerful physical game engine Uinty3D is adopted, and an infinite scene seamless splicing technology and an ultra-efficient dynamic loading technology are used, so that when a user operates and interacts, the response period is lower than the perception time of the user, and all required data are loaded and rendered in real time. The application runs at the PC end, driving is directly carried out through the bottom layer technology, program optimization is carried out on existing hardware, the maximum performance of the hardware is brought into play, memory occupation is reasonable, the computing capacity of a GPU is fully utilized in scene rendering, the scene rendering efficiency is improved, and meanwhile the processing pressure of a CPU is reduced. Program operation is smooth and stable, a scene is shocked, and the scene can be dynamically and infinitely expanded.

Description

technical field [0001] The invention relates to the technical field of smart cities, in particular to a three-dimensional visualization platform system for urban macro scenes. Background technique [0002] In recent years, with the development of science and technology and the drive of new urban development thinking, cities have continued to develop towards digitization and intelligence. The urban Internet of Things has become an important way to obtain data. Cities generate massive amounts of data every day, and how to display these data in real time, how to track data changes in real time, how to regulate the orderly operation of various functional institutions in the city in real time, and prevent urban risks. Due to the difference in roles, major city decision makers are more inclined to intuitively and macroscopically control urban data. Especially in the 3D scene based on the real geographic information system, there is a stronger demand for viewing data summary and ...

AI Technical Summary

Problems solved by technology

[0005] 1. Conventional technologies are mostly developed on browsers and cannot instantly render large scenes. Conventional dynamic loading logic will lead to slow loading and refreshing of scenes. The scene rendering cycle may be longer than user interaction time, resulting in interruption of user experience and poor user experience.

[0006] 2. Due to performance limitations, it is impossible to optimize the hardware in place, and the program is prone to crash, resulting in poor stability. Limited by performance limitations, the scale of the scene cannot be infinitely expanded, and it cannot be used for city macro effect display

[0007] 3. Long development cycle and high development cost

[0008] 4. Strong structural coupling, complex functions, long learning cycle for users, and it is difficult to directly display the data you need with one click, directly hitting the pain point
