Abstract

The invention relates to the technical field of generation methods, and discloses an urban building automatic generation method based on a land use planning map. The method comprises the following steps: S1, performing CAD data conversion; S2, generating a three-dimensional model; S3, turning points of polygonal surfaces; and S4, realizing a prototype system. According to the urban building automatic generation method based on the land use planning map provided by the invention, a tedious manual operation modeling method is changed into computer automation operation, so that the modeling method is perfected and improved.

Description

technical field [0001] The invention relates to the field of generating methods, in particular to a method for automatically generating urban buildings based on land-use planning maps. Background technique [0002] At present, the construction of digital cities is in full swing across the country, and the 3D modeling industry is also showing a thriving situation. In particular, various 3D modeling methods and modeling software are emerging one after another, which greatly enriches the theory of 3D modeling and promotes the development of 3D modeling. The competitive environment of modeling makes the 3D modeling industry develop rapidly. At the same time, due to the diversity and complexity of modern architectural forms, the heavy workload and trivial work, we still face the limitations and challenges brought by software and hardware technology when using computer software to automatically model. In order to make a more detailed and realistic 3D model so that it can more tru...
