Embodiment 1

[0060] Such as figure 1 As shown, the three-dimensional modeling method of the building of Embodiment 1 of the present invention comprises the following steps:

[0061] S 1 , according to an initial area, a number of buildings, a building distance threshold, a building density upper limit and a building density lower limit to generate several sub-areas; wherein the several sub-areas are all located in the initial area, and the number of sub-areas The number is equal to the number of buildings, the minimum distance between any two sub-regions is greater than the building distance threshold, and the ratio of the sum of the areas of the several sub-regions to the area of ​​the initial region is less than the upper limit of the building density and greater than the lower limit of the building density , where the minimum distance between any two subregions is equal to the shortest length of the line segment connecting any two subregions;

[0062] S 2 1. Generate a sub-area layer...

Embodiment 2

[0074] refer to figure 2 As shown, the difference between the three-dimensional modeling method of the building of embodiment 2 and embodiment 1 is only:

[0075] S 1 Include the following steps:

[0076] S 101 . Generate a boundary translation line according to the initial area, and the boundary translation line is obtained after the boundary of the initial area is translated inward by a translation distance;

[0077] S 102 1. Input at least one sticking rate threshold, the at least one sticking rate threshold corresponds to at least one sticking line segment respectively, and each sticking line segment is a segment of the border translation line;

[0078] S 103 1. Generate the several sub-areas according to the initial area, the number of buildings, the building distance threshold, the building density upper limit, the building density lower limit and the at least one sticking rate threshold.

[0079] The several sub-regions are all located in the initial region, the ...

Embodiment 3

[0085] refer to image 3 As shown, the difference between the three-dimensional modeling method of the building of embodiment 3 and embodiment 2 is only:

[0086] S 4 and S 5 Between also include:

[0087] S 41 , to execute S 4 After all the first heights are arranged, it is judged whether the ratio of the maximum value of the first height of any two sub-regions to the minimum distance between any two sub-regions in the several sub-regions is greater than a height distance coefficient, and S 4 Remove from the first height set of the sub-region obtained after that, and arrange the layers corresponding to the removed first height arrangement from the execution S 4 Removed from the layer set of the sub-area obtained later;

[0088] S 5 is: according to the several sub-areas and the implementation of S 41 The first height set of the sub-area and the layer number set of the sub-area obtained afterward are used to generate the three-dimensional model.

[0089] Setting the ...

Abstract

The invention discloses a three-dimensional modeling method for buildings. The three-dimensional modeling method for the buildings comprises the following steps of generating a plurality of subareas according to an initial area, the number of buildings, building interval threshold values, the upper limit value of building density and the lowing limit value of the building density, generating a subarea floor number set according to the plot ratio threshold value, the area of the subareas and the area of the initial area, generating a first height set of the subareas, removing first height arrays which are in inconformity of height range conditions and corresponding floor number arrays out of the sets, and generating a three-dimensional model according to the subareas, the subarea floor number set and the first height set of the subareas. The three-dimensional modeling method for the buildings can overcome the defect that the overall design of an area entirely relies on manpower in the prior art, further avoids the risk that the design mismatches control conditions which have to be met and cannot be adopted due to neglects of certain factors of manual design, and can play a comprehensive assisting role on the design of building plans.

Description

technical field [0001] The invention relates to a three-dimensional modeling method of a building. Background technique [0002] As we all know, a building needs to complete its design plan before construction, and then build according to the design plan, which defines the spatial structure of a building in detail. With the development of the city, for new buildings, not only its own spatial structure must be considered, but also the distribution of buildings formed by it and surrounding buildings in the city, and the impact on the overall space. One of the most important is the overall design of the buildings in the same area, how to make the buildings in an area not only more beautiful in overall appearance, but also more coordinated in mutual relationship and more reasonable in space distribution, suitable for People live, work, etc. Due to the complex factors involved in the overall design of buildings in an area, relying entirely on the designer to design the layout a...
