Method and system for building 3D model simulation based on homotopy mapping algorithm

Abstract

The invention discloses a building three-dimensional model simulation method and system based on the homotopy mapping algorithm. The method and system aim at solving the problems that the building is simulated with the existing rule shape, but the modeling and simulation of the buildings with changing shapes cannot be met and the sense of reality is in absence. According to the building three-dimensional model simulation method and system based on the homotopy mapping algorithm, the characteristic that the homotopy mapping algorithm can smoothly transit from one function to another function is used; a part of the two-dimensional information of the existing building is also used; the mapping function is generated; the contour of each storey of the building is worked out; the three-dimensional quick modeling of the existing building is realized, thus the real vivid simulation effect is achieved.

Description

technical field [0001] The invention belongs to the field of simulation, in particular to a method and system for building a three-dimensional model of a building based on a homotopy mapping algorithm. Background technique [0002] Three-dimensional city models have important applications in many fields of research, such as urban planning, architectural design, virtual city, evacuation simulation and other fields. Most of the 3D simulation of buildings in 3D city modeling still stays in the simple simulation of buildings with geometric cubes and maps. At present, there are also 3D point cloud data for simulation, but because of the data segmentation processing It is very complex and is mostly used for the simulation of regular buildings. [0003] With the development of the times and the diversification of building materials, the shape of modern buildings is no longer a regular cuboid, but more and more variable shapes, using curved surfaces, asymmetrical and other modeling...

AI Technical Summary

Problems solved by technology

Most of the 3D simulation of buildings in 3D city modeling is still simple simulation of buildings with geometric cubes and textures. At present, there are also 3D point cloud data for simulation, but because of the data segmentation processing Very complex, mostly used for simulation of regular buildings

Making regular shapes to simulate buildings can no longer satisfy the modeling and simulation of buildings with variable shapes, which lacks a sense of reality
