Abstract

The invention relates to the field of three-dimensional visualization. The invention relates to the technical field of urban landscape modeling, in particular to an urban landscape model three-dimensional visualization method and system, a medium and electronic equipment, and is characterized in that the method comprises the following steps: 101, partitioning a large-scene landscape model: partitioning a space model of a large scene, and partitioning each element to different space positions to achieve the purpose of relatively uniform overall distribution of the space model; 102, constructinga hierarchical model: performing hierarchical simplification on various entity models in the scene, and constructing a viewpoint-independent hierarchical model; 103, merging block model elements; 104, rendering and cutting the three-dimensional model data; 105, dynamically combining the top-level nodes: dynamically combining the scene nodes according to space division; 106, cache data compressionstorage. Mass data can be reasonably organized, managed, stored, transmitted and scheduled in real time, and user experience is greatly improved.

Description

technical field [0001] The invention relates to the field of three-dimensional visualization, in particular to a method, system, medium and electronic equipment for three-dimensional visualization of an urban landscape model. Background technique [0002] With the continuous acceleration of urban construction, the application of 3D landscape modeling technology has been paid more and more attention. In the computer, the real world is reproduced and shaped in the form of three-dimensional landscape modeling. Its important role is self-evident for urban development and construction planning. Its scope includes urban development, planning and management, as well as transportation, Communications, tourism and public safety, etc. [0003] The visualization of 3D scenes is one of the core contents of the current construction of "digital city", "smart city" and even "digital earth". In recent years, people's demand for the expression and processing of various 3D information in th...
