Abstract

The invention discloses a building-parameterization three-dimensional modeling method. The method comprises the following steps of acquiring a two-dimensional rule bottom surface of a building and parameterizing a front side orientation; vertically and upwardly stretching the bottom surface and forming a cube model; according to the front side orientation of the bottom surface, splitting the cube model into a top surface, left and right planes, a front side and a back side; executing a roof modeling rule on the top surface; executing a gable wall modeling rule on the left and right planes; and executing a house face modeling rule on the front side and the back side. In the invention, a historic building modeling module can be provided and historic building folk houses are further constructed.

Description

technical field [0001] The invention relates to architectural engineering, in particular to a parametric three-dimensional modeling method for buildings. Background technique [0002] In the 3D geographic information system, in order to carry out 3D modeling in batches and quickly, and support 3D parameter interactive operation, the existing technology uses the city engine platform to quickly build a 3D city model, and supports Html5 network 3D publishing, which can generate an independent 3D network geographic information system. However, there is a lack of ancient building modeling modules in the city engine platform, making it difficult to build ancient architectural dwellings. [0003] For the problem that it is difficult to construct ancient architectural dwellings in the prior art, there is no effective solution at present. Contents of the invention [0004] In view of this, the object of the present invention is to propose a parametric three-dimensional modeling m...
