Detailed Implementation

[0018] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0020] To address the aforementioned technical problems, this disclosure provides a method for optimizing a three-dimensional irregular-shaped curtain wall model. This will be described in detail through one or more of the following embodiments.

[0021] The optimization method for a three-dimensional irregular curtain wall model provided in this disclosure is applicable to optimization scenarios for three-dimensional irregular curtain wall models. This method can be executed by an optimization device for the three-dimensional irregular curtain wall model, which can be implemented in software and / or hardware and can be integrated into an electronic device. The electronic device can include, but is not limited to, mobile terminals such as smartphones, laptops, digital radio receivers, personal digital assistants (PDAs), tablet computers (Tablet PCs), PMPs (portable multimedia players), in-vehicle terminals (e.g., in-vehicle navigation terminals), wearable devices, etc., as well as fixed terminals such as digital televisions, desktop computers, smart home devices, etc.

[0022] Figure 1 A flowchart illustrating the optimization method for a three-dimensional irregular curtain wall model provided in this embodiment of the disclosure, specifically including as follows: Figure 1 The following steps are shown: S101. Rationalize the original surface of the three-dimensional irregular curtain wall model to obtain a rationalized surface.

[0023] The rationalized surface has uniform construction lines, which are composed of straight lines and circular arcs.

[0024] Understandably, a 3D irregular-shaped curtain wall model refers to a digital information model constructed using 3D digital technology (such as parametric design software) to represent the exterior facade of a building with non-standard geometric shapes. It can also be understood as a 3D model of an irregular-shaped curtain wall. Here, "irregular" means that the curtain wall surface is not a simple plane, cylinder, or sphere, but a complex, non-repeating, hyperbolic, or free-form surface, such as a twisted surface, a wavy surface, or an irregular surface. The original curved surface can be understood as the surface to be displayed in the 3D irregular-shaped curtain wall model, like the "skin" or "mold" of the building facade. It is the starting point and foundation of the entire curtain wall system design; subsequent panel division, keel arrangement, structural design, etc., are all based on the original curved surface. For example, Figure 2 This is a schematic diagram of the original curved surface provided in the embodiments of this disclosure. The construction lines of the original curved surface are uneven, and the construction lines at the corners are too dense, which will affect the quality and flatness of the curved surface. In addition, when constructing different real curtain walls according to the three-dimensional irregular curtain wall model, different construction materials will also affect the cost. Therefore, the original curved surface needs to be rationalized to reduce costs while meeting construction requirements. Here, the construction lines can be understood as the grid lines on the original curved surface.

[0025] Understandably, the original surface can be rationalized using the equidistant section line method and / or the contour edge method to obtain the median line, thus yielding a rationalized surface. For example, Figure 3This is a schematic diagram of a rationalized surface provided in an embodiment of the present disclosure. The UV construction lines of the rationalized surface are uniform and are composed of straight lines and arcs. The entire surface is not only smoother but also more aesthetically pleasing, and it is also convenient for subsequent segment analysis.

[0026] Optionally, the rationalization process of the original surface of the three-dimensional irregular curtain wall model to obtain a rationalized surface can be achieved through the following steps: The contour edges of the original surface are calculated, and the original surface is divided into a first type of surface and a second type of surface according to the contour edges. The curvature of the first type of surface is greater than that of the second type of surface. At least one intermediate line is calculated proportionally on the first type of surface to obtain a rationalized first surface. The second type of surface is rationalized using the equidistant section line method to obtain a second surface. The rationalized surface includes the first surface and the second surface.

[0027] Understandably, calculating the contour lines of the original surface refers to the locations where the Gaussian curvature or average curvature of the surface changes significantly. That is, the boundary lines between highly curved regions (such as domes or twisted sections) and relatively flat regions (such as extended surfaces or gentle slopes). The contour lines can also be understood as feature boundaries. These boundaries are not the physical boundaries of the surface, but rather inherent geometric feature lines used to logically partition the surface morphology. Based on these contour lines, complex hyperboloid panels can be distinguished from simple single-curved or near-flat panels to optimize manufacturing difficulty and construction costs (e.g., the high cost of hyperboloid panel molds). Specifically, the contour lines can be used to divide the original surface into two types: Type I surfaces and Type II surfaces. Type I surfaces have a greater curvature than Type II surfaces. Type I surfaces are highly curved, while Type II surfaces are relatively flat (e.g.,...). Figure 2 The original surface shown is not limited in the number of surfaces of each type, meaning the original surface can be divided into multiple sub-regions of various types. Then, for the first type of surface (highly curved surfaces), at least one intermediate line is calculated proportionally between the contour edge and the surface boundary line to obtain the rationalized first surface. For the second type of surface (i.e., relatively flat surfaces), the equidistant section line method is used for rationalization to obtain the second surface (e.g., ...). Figure 3 The rationalized surface (as shown) and the equidistant section line method refer to a method of continuously cutting a three-dimensional surface along one or more preset directions at equal intervals (distances) to generate a set of parallel cross-sectional curves (section lines). The rationalized surface includes all the first surfaces and all the second surfaces.

[0028] For example, Figure 4The schematic diagram of surface transformation provided in this embodiment includes an original surface 410, an intermediate surface 420, and a rationalized surface 430, all marked with contour lines. The contour lines divide the entire original surface into a hyperbolic panel and a near-planar panel. Based on the original surface 410, the near-planar panel is rationalized using the equidistant section line method. Along the grid lines in the near-planar panel in the X direction, the grid lines in the X direction of the hyperbolic panel are determined, and the hyperbolic panel is partially rationalized to obtain the intermediate surface 420. The intermediate line is then proportionally calculated on the hyperbolic panel shown in the intermediate surface 420 to complete the rationalization of the hyperbolic panel, resulting in the rationalized surface 430.

[0029] Optionally, the rationalization process of the second type of surface using the equidistant section line method to obtain the second surface includes: Along the Z-axis, extract a line every first threshold as a construction line in the U-direction; along the X-axis or Y-axis, extract a line every second threshold as a construction line in the V-direction; and reconstruct a smooth second surface with uniform construction lines on the second type of surface using the construction lines in the U-direction and the construction lines in the V-direction.

[0030] Understandably, a line is extracted along the Z direction at approximately the first threshold (e.g., 2000 mm) as a U-direction construction line, and a line is extracted along the negative X direction at approximately the second threshold (e.g., 2500 mm) as a V-direction construction line. A smooth surface with uniform construction lines is then reconstructed using these UV-direction construction lines, resulting in the second surface. Understandably, the construction of the second surface can be achieved using the contour command in Grasshopper (GH), a visual programming or parametric modeling plugin that runs within the Rhinoceros 3D (Rhino) software environment.

[0031] Optionally, after rationalizing the original surface of the three-dimensional irregular curtain wall model to obtain a rationalized surface, the method further includes: Multiple points are selected on the rationalized surface; the distances from the multiple points to the original surface are calculated to obtain multiple distances; the maximum distance is determined among the multiple distances, wherein the maximum distance is the maximum value of the surface deviation between the rationalized surface and the original surface; if the maximum distance is less than a third threshold, it is determined that the fit between the rationalized surface and the original surface meets the deviation requirement, so as to perform grid analysis on the rationalized surface.

[0032] Understandably, a difference analysis is performed on the rationalized surface and the original surface to determine whether the fit between the two surfaces meets the deviation requirements. For example, a point-based method can be used for difference analysis. Specifically, multiple points (e.g., 1000 points) are randomly selected on the rationalized surface, and the distance from each point or a subset of points on the rationalized surface to the original surface is calculated using the GH (Highlighter) calculator, resulting in multiple distances. Subsequently, the maximum value (i.e., the maximum distance) is found among these multiple distances. This maximum value represents the largest deviation between the two surfaces. For example, if the maximum deviation between the two surfaces is 25mm, the fit between the two surfaces meets the deviation requirements, the rationalization process is valid, and subsequent grid analysis is performed on the rationalized surface.

[0033] It is understandable that after obtaining either the first or second surface, one can determine whether the fit between the partially rationalized surface and the original surface meets the deviation requirements, or one can obtain the complete rationalized surface and then uniformly determine whether it meets the deviation requirements. No limitation is made here.

[0034] For example, Figure 5 A schematic diagram of another rationalized surface provided in this embodiment of the present disclosure, specifically referring to... Figure 2 The original full and shown Figure 3 The diagram shows a rationalized surface analyzed by the point placement method for difference analysis. The "×" in the diagram represents multiple randomly selected points.

[0035] Optionally, after rationalizing the original surface of the three-dimensional irregular curtain wall model to obtain a rationalized surface, the method further includes: The grid information is marked and displayed on the rationalized surface, wherein the grid information includes at least one of line segment type, line segment size, precision, distance and angle.

[0036] Understandably, after rationalizing the surface, the generated mesh system can be annotated and visualized. For example, on the rationalized surface, key engineering data of the divided mesh (lines composed of keels, panel boundaries, etc.) can be clearly marked and displayed intuitively in the GH interface. Mesh information includes at least one of the following: line segment type, line segment size, precision, distance, and angle. The line segment type indicates whether a line is a vertical keel, horizontal keel, main structural line, grid line, or boundary line, clarifying its function in the mesh system. The line segment size indicates the length of the line segment, facilitating material cutting and processing. Precision indicates the allowable manufacturing or installation error range (e.g., ±2mm) for the line segment or its area. Distance indicates the spacing between two lines (e.g., keel spacing 1200mm), a core parameter for grid design. Angle indicates the angle between two intersecting lines, guiding node design and processing positioning. By annotating the grid information, abstract geometric models can be transformed into constructible drawings containing rich engineering data, making it easier for designers, engineers, manufacturers, and construction parties to quickly understand the design intent and ensure the accuracy of processing and installation.

[0037] For example, Figure 6 This is a schematic diagram of another rationalized surface provided in an embodiment of the present disclosure. The rationalized surface shown in Figure 430 is annotated, and the battery annotation grid information can be obtained through GH.

[0038] S102. Perform grid analysis on the rationalized surface using at least one preset segmentation strategy to obtain at least one gridded surface.

[0039] Understandably, based on the above S101, different partitioning rules (segmentation strategies) are applied to the rationalized surface to generate a variety of possible panel layout schemes, resulting in a variety of segmented surfaces. For example, the segmentation strategy specifies generating quadrilateral or triangular panels and dividing along the U / V direction at fixed intervals (such as 1500mm), while other possible segmentation rules are not limited.

[0040] For example, Figure 7 Figures 710 and 720 are schematic diagrams of two segmented surfaces provided in embodiments of this disclosure. Figure 3 The grid analysis shown is based on rationalized grids, and both are quadrilateral panels, but the fixed distances between them along the U / V directions are different, that is, the grid sizes are different.

[0041] S103. Calculate the curvature of the at least one segmented surface, and select a target segmented surface from the at least one segmented surface according to the curvature to complete the optimization of the three-dimensional irregular curtain wall model.

[0042] Understandably, based on S102 above, the proportions (i.e., curvature ratios) of flat plate meshes, single-curved meshes, and hyperbolic meshes in each segmentation scheme are calculated. The scheme with the lowest curvature ratio (i.e., closer to a plane and easier to construct) is selected as the optimal target segmentation surface to complete the curtain wall optimization. Other possible selection methods are not limited and can be determined according to user needs.

[0043] Optionally, calculating the surface index of the at least one segmented surface includes: Divide the multiple grids included in the at least one segmented surface into flat grids, monocured grids, and hypercured grids; calculate the area of ​​each of the flat grids, monocured grids, and hypercured grids; and calculate the surface rate based on the area of ​​each of the flat grids, monocured grids, and hypercured grids.

[0044] Understandably, multiple meshes on a segmented surface are categorized into three types based on their geometric characteristics: flat meshes, single-curved meshes, and hyperbolic meshes. Flat meshes represent planar portions with little or no curvature; single-curved meshes are curved in one direction but remain straight in another, forming part of a cylindrical or cylindrical surface; and hyperbolic meshes are curved in both directions, forming part of a complex surface. The areas of each type of mesh are then calculated to quantify the proportion of the total surface area occupied by each type. Based on these area calculations, the curvature of each segmented surface is further calculated. Curvature refers to the proportion of each type of surface (flat, single-curved, hyperbolic) relative to the total area of ​​the segmented surface; that is, assessing the proportion of each type of surface within the entire segmented surface. The target segmented surface is then selected from multiple segmented surfaces based on the proportion of hyperbolic surfaces. This method effectively analyzes the distribution of meshes of different complexities within a segmented surface, which is significant for cost estimation, manufacturing process selection, and installation planning.

[0045] For example, Figure 8 Schematic diagrams of two other segmented surfaces provided in embodiments of this disclosure. Figure 8 Marked Figure 7 The two types of segmented surfaces each contain flat, single-curved, and hyperbolic types, so as to more intuitively understand the distribution of flat, single-curved, and hyperbolic surfaces on the segmented surfaces. Specifically, this includes 810 corresponding to Figure 710 and 820 corresponding to Figure 720.

[0046] Optionally, after optimizing the three-dimensional irregular curtain wall model, the method further includes: Obtain the structural data of the installation site of the three-dimensional irregular curtain wall model, and adjust the three-dimensional irregular curtain wall model according to the mapping parameters obtained by three-dimensional mapping of the structural data; and / or, actually process and manufacture a mold according to the three-dimensional irregular curtain wall model, and compare and analyze the scanning data of the mold with the three-dimensional irregular curtain wall model to adjust the three-dimensional irregular curtain wall model.

[0047] Understandably, the 3D irregular-shaped curtain wall digital model can also be verified and corrected in actual engineering projects. Specifically, it can be corrected before installation by obtaining actual structural data from the building site (such as through 3D laser scanning), and adjusting the curtain wall model based on the measurement results to adapt to deviations in the actual site. It can also be corrected after manufacturing; after the mold is made, the actual mold is scanned, and the data obtained from the scan is compared with the original design model. Further adjustments to the curtain wall model are made based on the differences to ensure the accuracy of the final product. Through these two feedback methods—on-site surveying and mold scanning—a closed-loop calibration between the digital model and physical reality is achieved, ensuring the accuracy of the curtain wall installation.

[0048] This disclosure provides an optimization method for a three-dimensional irregular curtain wall model. By introducing parametric technology for model optimization design of the three-dimensional irregular curtain wall, it realizes the transformation from traditional manual modeling to digital and batch processing. This significantly improves efficiency, reduces costs, and ensures quality in all stages of design, construction, and operation and maintenance, making it an indispensable technical means for irregular projects. Secondly, the three-dimensional model intuitively presents the complex geometric shape of the curtain wall, ensuring the final effect and effectively verifying the feasibility of hyperbolic complex curtain wall shapes, especially suitable for irregular curved curtain walls. It avoids measurement errors from two-dimensional drawings, ensuring accurate realization of the architectural effect. Furthermore, the segmentation optimization significantly reduces the proportion of hyperbolic panels, saving material and mold costs. Simultaneously, it improves the overall collaborative efficiency, shortens the construction period, and ensures construction quality.

[0049] Based on the above embodiments, Figure 9 This is a schematic diagram of the structure of the optimization device for a three-dimensional irregular curtain wall model provided in this embodiment of the disclosure.

The segmentation unit 902 is used to perform segmentation analysis on the rationalized surface using at least one preset segmentation strategy to obtain at least one segmented surface. The optimization unit 903 is used to calculate the curvature of the at least one segmented surface, and select a target segmented surface among the at least one segmented surface according to the curvature, so as to complete the optimization of the three-dimensional irregular curtain wall model.

[0050] Optionally, the acquisition unit 901 is used for: Calculate the contour edge of the original surface, and divide the original surface into a first type of surface and a second type of surface according to the contour edge, wherein the curvature of the first type of surface is greater than that of the second type of surface. Calculate at least one intermediate line on the first type of surface proportionally to obtain the rationalized first surface; The second type of surface is rationalized using the equidistant cross-sectional line method to obtain the second surface, wherein the rationalized surface includes the first surface and the second surface.
