Background
In existing three-dimensional modeling software, the service parameters of the component are usually bound with the geometric model.

Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
Referring to fig. 1, the present embodiment provides a method for generating a three-dimensional member, including the following steps:
And S100, determining a geometric model corresponding to the target component, wherein the geometric model comprises first geometric parameters, and the first geometric parameters are used for representing the appearance display effect of the geometric model.
The target member in the present invention may include any individual member or combination member in the construction field, such as a wall, a column, a beam, etc. The geometric model refers to an intermediate carrier that generates a three-dimensional model of the target component (i.e., a three-dimensional component) for representing geometric features of the three-dimensional component. For example, the target member is a wall body in a certain direction in a building, and the three-dimensional member corresponding to the target member is a three-dimensional wall body model with characteristics of specific size, color, material and the like. It will be understood by those skilled in the art that the necessary condition for generating the three-dimensional wall model is to obtain a solid geometric model consistent with the shape of the three-dimensional wall model, and finally obtain the three-dimensional wall model by assigning values to parameters of the geometric model.
The invention can preset a model library which stores a plurality of geometric models, such as cuboid, cube, cylinder, cone and the like, which respectively correspond to a plurality of three-dimensional shapes. So that the user can select a geometric model conforming to the intended shape of the target member directly from the model library. The different geometric models are defined by different first geometric parameters, for example, a cuboid may be defined by a length, a width, a height, a sphere may be defined by a radius, a stretched body may be defined by a cross-sectional shape, a stretched path, etc., where the length, the width, the height, the radius, the cross-sectional shape, the stretched path, etc. are the first geometric parameters corresponding to the different geometric models in this embodiment. It will be appreciated that, upon determining the geometric model, the first geometric parameter corresponding to the geometric model may be directly obtained.
S200, acquiring service parameters corresponding to the target component.
The service parameters refer to various characteristic parameters of the component in the specific service field, such as positioning parameters of top elevation, bottom elevation, etc., dimensional parameters of length, width, height, etc., material parameters, color parameters, etc., which are not listed one by one in this embodiment. These business parameters may be data that the user directly inputs or selects.
It will be appreciated that the same geometric model, when corresponding to different target components, may have different business parameters to be obtained. For example, the same cuboid aggregate model may include parameters 1,2, and 3 for the corresponding service parameters when used as a shear wall, and parameters 2, 3, and 4 for the corresponding service parameters when used as a lintel. The background program of the present embodiment determines a list of service parameters returned to the user according to the target member and the geometric model determined in step S100, so that the user can input or select a specific numerical value in the list. The service parameter list required to be returned when the geometric model is applied to different target components can be stored in the data table in advance, and the corresponding service parameter list is returned in a table look-up mode after the target components and the geometric model are designated by a user.
S300, according to a mapping relation between a preset first geometric parameter and a service parameter, determining a corresponding first geometric parameter in the geometric model based on the service parameter.
The purpose of establishing the mapping relationship between the first geometrical parameters and the service parameters is to determine how the service parameters entered by the user are to be applied to the body features of the geometrical model. Taking the target member as a shear wall and the geometric model as a cuboid as an example, the mapping relationship can comprise a corresponding relationship between the wall thickness in the service parameter and the side length of one side in the first geometric parameter. It can be seen that by constructing a mapping relationship between the first geometric parameter of the geometric model and the service parameter of the target component, it can be ensured that the geometric model accurately presents specific morphological features of the component according to different service parameters.
S400, generating a three-dimensional model of the target component according to the geometric model of the first geometric parameter.
On the basis of determining the mapping relation, the change of the first geometric parameter is matched with the change of the service parameter through direct assignment or indirect calculation. The specific steps may include obtaining a constraint relationship preset in the geometric model; the target member is generated from the constraint relationship and the first geometric parameter. Wherein constraint relations are used to characterize how each of said first geometrical parameters affects said geometrical model, e.g. when the length of a line segment changes from 2cm to 5cm, in particular from which end point of the line segment extends, etc. Thus, the three-dimensional component model can be quickly and accurately generated through the first geometric parameters and the constraint relation.
Through the steps, the service parameters of the target components and the geometric parameters of the geometric model are separated, different target components and different geometric models can be combined at will according to service requirements, and corresponding service parameters under different combined modes can be determined through a table look-up mode. The mode of separating the service parameters from the geometric parameters can be used for more flexible personalized customization, and different service requirements of enterprises are met. Further, by separating the aggregate parameters and the service parameters, the method is also beneficial to meeting the user's fine requirements on parameter filtering, data encryption and the like, thereby improving the working efficiency and the user experience.
In one example, the present invention provides the following several specific implementations of determining a geometric model corresponding to a target component, one of which may be optional as desired:
Mode one: and acquiring a pre-stored standard geometric model from a model library, wherein the standard geometric model is generated by a standard section graph according to a corresponding entity creation mode. Wherein the standard interface graphic comprises a common regular two-dimensional shape such as rectangular, circular, triangular, etc. The entity creation means comprises a conventional point type, a conventional line type, a profile stretching body, a line lofting body and the like, and it is understood that different geometric models can be generated by different entity creation means. The method is mainly applicable to regular and common component design scenes, such as walls extending along straight lines and having consistent heights, cylindrical side columns and the like.
Mode two: and adjusting on the basis of the standard geometric model to obtain a first custom geometric model. The method is suitable for a scene with the shape of the target component being relatively close to that of the standard geometric model, and can be obtained by adjusting a first standard section graph or a first entity creation mode in the standard geometric model.
The implementation steps of the method comprise:
And acquiring a first standard section graph and a first entity creation mode for generating the standard geometric model. For example, for a line loft 1 in a standard geometric model, its corresponding cross-sectional profile 1 and loft path 1 may be obtained.
And generating the first custom geometric model from the first standard section graph according to a second entity creation mode, wherein the second entity creation mode is different from the first entity creation mode. Assuming that the shape of the target member is consistent with the cross-sectional pattern of the line loft body 1, but the loft path is not consistent, for example, the loft path 1 is a straight line, and the loft path 2 of the target member is a curved line. At this time, the line type lofting body 2 can be obtained after lofting through the lofting path 2 based on the section graph 1, which is the first custom geometric model determined in the second mode in this embodiment.
Mode three: a second custom geometric model is generated based on the custom cross-sectional graph. The method is applied to a scene with a larger shape and standard geometric model of the target component, namely the section patterns are completely different. At this time, a third section graph corresponding to the target component can be obtained through uploading by a user or manually drawing, and a second custom geometric model can be generated according to a third entity creation mode selected by the user. The method has high flexibility, and a user can generate a geometric model with any shape according to the needs.
Through the three modes of obtaining the geometric model, the method and the device can be suitable for target components with any shape, and the three-dimensional modeling efficiency and accuracy of irregular components are improved.
In this embodiment, the mapping relationship between the first geometric parameter and the service parameter may include a direct mapping relationship or an indirect mapping relationship. In one example, an intermediate transition of model templates is added between the target component and the aggregate model, through which an indirect mapping between the first geometric parameters and the business parameters is achieved. Fig. 2 shows a schematic flow chart of determining a first geometrical parameter according to a mapping relation according to a first embodiment of the invention. As shown in fig. 2, step S300 includes:
and S310, determining a model template corresponding to the geometric model according to the template category, wherein the model template comprises second geometric parameters.
The model templates in this embodiment are further classification of the target components, and can be used as specific application objects of the geometric model. For example, the wall body is also formed by a cube geometric model, which can correspond to a bearing wall with equal floor spacing or a parapet wall suspended at the upper part, wherein the bearing wall and the parapet wall can be used as model templates. It will be appreciated that the second geometric parameters that it contains are also different for corresponding and different model templates. The second geometric parameters corresponding to each model template can be stored in the database in advance, and the corresponding second geometric parameters can be called through the database on the basis of determining the model template.
S320, a first mapping relation preset between the second geometric parameter and the first geometric parameter and a second mapping relation preset between the service parameter and the second geometric parameter are obtained.
When the model template is used as an intermediate transition body, a first mapping relation between the model template and the geometric model, namely, a mapping relation between the second geometric parameter and the first geometric parameter, and a second mapping relation between the target component and the model template, namely, a mapping relation between the service parameter and the second geometric parameter, can be preset. FIG. 3 shows a schematic diagram of the relationship between a target member, a model template, and a geometric model. As can be seen from fig. 3, the model template is located between the target member and the geometric model, and a first mapping relationship and a second mapping relationship are established with the model template and the geometric model respectively.
S330, determining a third mapping relation between the first geometric parameter and the service parameter according to the first mapping relation and the second mapping relation, and determining a first geometric parameter corresponding to the service parameter according to the third mapping relation.
In one example, the first mapping relation in the present invention includes a mapping relation between a positioning parameter in the second geometric parameter and a section parameter in the first geometric parameter, and the second mapping relation includes a mapping relation between an elevation parameter in the service parameter and a positioning parameter in the second geometric parameter. Fig. 4 shows a schematic diagram of a mapping relationship between service parameters and geometric parameters according to an embodiment of the present invention. As shown in fig. 4, the target component comprises a wall, and the corresponding service parameters comprise a foundation elevation, a wall height, a wall thickness and a structural material; the model template comprises a common wallpaper template and a plate template, wherein the second geometric parameters corresponding to the common wallpaper template comprise top correlation, bottom correlation, top offset, bottom offset, height and thickness, and the second geometric parameters corresponding to the plate template comprise contour, top correlation, top offset and wall thickness; the geometric model comprises a line type lofting body and a profile stretching body, wherein first geometric parameters corresponding to the line type lofting body comprise lofting paths, section heights, section widths and Z-axis positioning, and first geometric parameters corresponding to the profile stretching body comprise profiles, thicknesses and Z-axis positioning. Fig. 4 also shows the correspondence between different parameters, for example, the height of the wall in the service parameter corresponds to the height in the second geometrical parameter, which in turn corresponds to the height of the section in the first geometrical parameter, so that it can be determined that the height of the wall in the service parameter has a correspondence with the height of the section in the first geometrical parameter. Thus, the section height parameters in the geometric model can be determined on the basis of obtaining the wall height parameters of the target member input by the user.
The flexibility of the geometric model for simulating the target component can be further increased by setting the model template between the target component and the geometric model and establishing the first mapping relation and the second mapping relation, and when the first geometric parameters of the geometric model are insufficient to reflect all service parameters such as positioning parameters in all target components, the mapping relation between the two is clearer through the model template, so that the accuracy of three-dimensional modeling of the component is improved.
With continued reference to fig. 5, in this embodiment, the three-dimensional component generating apparatus 50 may include or be divided into one or more program modules, where the one or more program modules are stored in a storage medium and executed by one or more processors to complete the present invention and implement the three-dimensional component generating method described above.
