Urban building three-dimensional visualization method

Abstract

The invention discloses an urban building three-dimensional visualization method. The method comprises the following steps: constructing an urban building three-dimensional model; partitioning the three-dimensional model: dividing the three-dimensional model of the urban building into space models of different areas according to categories; carrying out overall visualization and regional visualization on the three-dimensional visualization of the urban building, achieving data reading, and carrying out color rendering or texture mapping; and integrating the spatial models after color rendering or texture mapping to form a complete urban building three-dimensional visual model. According to the method, the three-dimensional model of the urban building is divided into space models of different regions according to categories; the spatial models after color rendering or texture mapping are integrated to obtain the urban building three-dimensional visual model, the mass data processing process can be simplified, rendering of various large-scale complex buildings is accelerated on the premise of ensuring the sense of reality, the execution efficiency of three-dimensional interaction software is improved, and the experience feeling of a user is greatly improved.

Description

technical field [0001] The invention relates to the technical field of visualization of smart city buildings, in particular to a three-dimensional visualization method of city buildings. Background technique [0002] Smart city is a new concept and new model of current urban development. It is the inevitable result of the development of digital city to a certain stage and the continuous development of scientific and technological progress. It is of great significance to the realization of people-oriented, comprehensive, coordinated and sustainable scientific development of cities. The three-dimensional visualization of urban buildings is one of the core contents of building a smart city. In recent years, people's demand for the expression and processing of various 3D information in urban buildings has become increasingly urgent. The constant pursuit of large-scale, high-quality, and high-resolution 3D visual effects has made the accuracy of architectural models continue to i...

Problems solved by technology

In recent years, people's demand for the expression and processing of various 3D information in urban buildings has become increasingly urgent. The constant pursuit of large-scale, high-quality, and high-resolution 3D visual effects has made the accuracy of architectural models continue to increase. The amount of 3D data It is very huge, and the data volume of some data can reach TB level, which brings great challenges to 3D visualization
