Technical Field

[0001] The present application relates to the technical field of parametric modeling, and in particular to a method, apparatus, computer equipment, storage medium and computer program product for parametric construction of an insulator string model. Background Art

[0002] Open CASCADE, referred to as OCC, is an open source CAD / CAM / CAE geometry model core, originated from the French company Matra Datavision. It is widely used in the industrial field, especially in the development of 2D and 3D geometry modeling applications, including general or professional computer-aided design CAD systems, manufacturing or analysis applications, simulation applications or graphic presentation tools. In addition, there is also a mainstream library OPENSCAD that can be used for model parametric construction. Compared with OCC, OPENSCAD started later. Although both are open source software, OPENSCAD's community is not active enough and BUG repairs are not as responsive as OCC.

[0051] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0052] The parameterized construction method of the insulator string model provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown, the terminal 102 communicates with the server 104 through a network. The data storage system can store data that the server 104 needs to process. The data storage system can be integrated on the server 104, or placed on the cloud or other network servers.

[0053] The terminal 102 may be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, IoT devices, and portable wearable devices. The IoT devices may be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. The portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc. The server 104 may be implemented as an independent server or a server cluster consisting of multiple servers.

[0054] In one embodiment, Figure 2 As shown in the figure, a parameterized construction method of an insulator string model is provided, and the method is applied to Figure 1 The server in the example is used to illustrate the following steps:

[0055] Step 202: Taking the insulator string to be constructed as a model object, inputting the parameters of the model object into a preset programming library.

[0056] Among them, the insulator string refers to a component that combines two or more insulator elements to flexibly suspend the conductor. The insulator string is a protective device with fixing and operation requirements, used to suspend the conductor and insulate the conductor from the tower and the ground; the programming library refers to the dll file, and other developers can also reference the corresponding dll file when doing software development.

[0057] Specifically, the insulator string to be constructed is taken as a model object, and the parameters of the model object are input into a preset programming library; wherein the parameters of the model object include the number of connections, double string spacing, the number of insulator pieces in a single string, the connection height of a single insulator piece, the large shed radius, the small shed radius, the insulator string radius, the front end length, the rear end length and the number of connection conductor splits.

[0058] Step 204, dividing the model object into multiple groups of basic primitives, and creating the basic primitives respectively; the basic primitives include simple basic primitives and special basic primitives.

[0059] Specifically, the model object is divided into multiple groups of basic primitives, and the way of dividing the model object into basic primitives is in a preset way. Basic primitives are basic elements constituting the model object, and basic primitives include simple basic primitives and special basic primitives. Special basic primitives require simple basic primitives to be created by performing intersection, union and / or difference, and simple basic primitives and special basic primitives are created separately.

[0060] Step 206: construct a rendering tree of the model object based on the basic primitives.

[0061] Specifically, each node in the rendering tree corresponds to a basic primitive and a corresponding key value. The rendering tree of the model object is constructed based on the basic primitive. The rendering tree is a binary tree structure. If the insulator pieces that constitute the insulator string are the same but have different positions, then the insulator piece as a basic primitive corresponds to a key, and the basic primitive can be found through the key.

[0062] Step 208: Generate a model of the model object based on the rendering tree.

[0063] Specifically, a model of a model object is generated based on a render tree, and the model of the model object is saved in a preset format. Existing tools support fewer formats when exporting created models. The method of this embodiment not only supports the basis of mainstream model formats on the market, but also supports FBX, glb and other formats.

[0064] In the parametric construction method of the insulator string model, the insulator string to be constructed is used as the model object, the parameters of the model object are input into a preset programming library, the model object is divided into multiple groups of basic primitives, and the basic primitives are created respectively; wherein the basic primitives include simple basic primitives and special basic primitives. A rendering tree of the model object is constructed based on the basic primitives, and a model of the model object is generated based on the rendering tree. By dividing the model object into multiple groups of basic primitives and creating the basic primitives respectively, the reuse of multiple small components in a model is achieved.

[0065] In one embodiment, dividing the model object into a plurality of groups of basic primitives and creating the basic primitives respectively comprises:

[0066] Dividing the model object into a plurality of groups of basic graphic elements according to a preset splitting rule;

[0067] A simple basic primitive is created, and a unique key is set for the simple basic primitive; the simple basic primitive includes at least one of a cylinder, a cone, a cube and a cuboid.

[0068] Specifically, the model object is composed of multiple groups of basic primitives. The model object is divided into multiple groups of basic primitives according to the preset splitting rules, and then simple basic primitives are created, and a unique key is set for the simple basic primitives. The basic primitives can be found through the key. Among them, the simple basic primitives include at least one of a cylinder, a cone, a cube and a cuboid, which can be set as needed.

[0069] In this embodiment, the model object is divided into multiple groups of basic primitives according to preset splitting rules, and simple basic primitives are created, and unique keys are set for the simple basic primitives, thereby supporting model reuse. For example, a large model is composed of several small components, and these small components are often the same, but the positions of these components are different. Therefore, the small components can be reused to reduce the model size without affecting the refinement.

[0070] In one embodiment, dividing the model object into a plurality of groups of basic primitives and creating the basic primitives respectively further comprises:

[0071] Create a special basic primitive and set a unique key for the special basic primitive.

[0072] Specifically, the creation of basic primitives includes not only the creation of simple basic primitives but also the creation of special basic primitives. The special basic primitives are created by obtaining the intersection, union and / or difference of simple basic primitives.

[0073] In this embodiment, by creating special basic primitives and setting unique keys for the special basic primitives, the creation of special basic primitives and the reuse of special basic primitives are achieved.

[0074] In one embodiment, creating a special basic primitive and setting a unique key for the special basic primitive includes:

[0075] Create basic primitives of topological structure based on the preset Open CASCADE;

[0076] Performing intersection, union and / or difference processing on a plurality of basic graphic elements of the topological structure to obtain the special basic graphic element;

[0077] The special basic primitive is triangulated to generate and store vertex information, and a unique key is set for the special basic primitive.

[0078] Specifically, when creating a special basic primitive, a basic primitive of a topological structure is created based on the preset Open CASCADE, and then the basic primitives of multiple topological structures are subjected to intersection, union, or / and difference processing to obtain a special basic primitive, and the type of the special basic unit is set as required. Afterwards, the special basic primitive is triangulated, vertex information is generated and stored, and a unique key is set for the special basic primitive. The parametric construction tool in this embodiment can generate three different precision models of high, medium, and low according to requirements.

[0079] In this embodiment, basic primitives of a topological structure are created based on the preset Open CASCADE, and intersection, union, and / or difference processing is performed on the basic primitives of multiple topological structures to obtain special basic primitives. Finally, the special basic primitives are triangulated to generate and store vertex information. At the same time, a unique key is set for the special basic primitive, thereby realizing the creation of special basic primitives and realizing the reuse of special basic primitives.

[0080] In one embodiment, constructing the rendering tree of the model object based on the basic primitives includes:

[0081] Constructing a rendering tree of the model object, and calculating a matrix of basic graphics elements constituting the model object according to the parameters of the model object;

[0082] The matrix and key value of each basic primitive are stored in the corresponding node in the rendering tree.

[0083] Specifically, a rendering tree of the model object is constructed, and the matrix of each basic primitive that constitutes the model object is calculated according to the parameters of the model object, and the matrix information contains the position information of the corresponding basic primitives; the matrix and key value of each basic primitive are stored in the corresponding node in the rendering tree, and each node corresponds to a basic primitive or a group of multiple basic primitives.

[0084] In this embodiment, by constructing a rendering tree of the model object, the matrix of each basic primitive that constitutes the model object is calculated according to the parameters of the model object, and the matrix and key value of each basic primitive are stored in the corresponding node in the rendering tree, the construction of the rendering tree is realized, creating the prerequisite for further generating the model.

[0085] In one embodiment, generating the model of the model object based on the rendering tree includes:

[0086] The rendering tree is written to a preset text file to generate a model of the model object.

[0087] Specifically, when a model corresponding to a model object is generated based on a rendering tree, the rendering tree is written to a preset text file to generate a model of the model object; in addition to supporting the basis of mainstream model formats on the market, the method of this embodiment also supports FBX, glb and other formats.

[0088] In this embodiment, by writing the rendering tree to a preset text file, a model of the model object is generated. In addition to supporting the general model description file format, the required format can also be customized, and multiple widgets in a model can be reused.

[0089] Existing parametric modeling platforms are often self-contained, such as platforms based on BIM standards, which cannot meet the customization needs of users. Although FreeCAD also provides a basic library for use to customize its own parametric modeling platform, as a rising star, its maintenance status and bug fixes are relatively slow. In addition to supporting the general model description file format, the parametric modeling in this embodiment can also customize the format.

[0090] Although existing platforms also provide model simplification solutions, they are unable to achieve precise control during the generation process. For example, a complete model is often composed of multiple small components. The platform in this embodiment can control the fineness of a small component, and can also control the fineness of the entire model file as a whole, and provide three levels of high, medium and low to choose from.

[0091] Although the model can be simplified and its size can be reduced by controlling the model's precision, in most cases it is not desirable to sacrifice accuracy in exchange for a reduction in size. Therefore, the platform in this embodiment also supports model reuse. For example, a large model is composed of several small components, and these small components are often the same, but the positions of these components are different. Therefore, the small components can be reused to reduce the model size without affecting the precision.

[0092] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0093] Based on the same inventive concept, the embodiment of the present application also provides a device for parameterizing the construction of an insulator string model for implementing the method for parameterizing the construction of an insulator string model involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in the embodiments of one or more device for parameterizing the construction of an insulator string model provided below can refer to the limitations of the method for parameterizing the construction of an insulator string model above, and will not be repeated here.

[0100] In one embodiment, the primitive creation module 402 is further used to: create a special basic primitive and set a unique key for the special basic primitive.

[0103] In one embodiment, the model generation module 404 is specifically used to write the rendering tree to a preset text file to generate a model of the model object.
