Currently, there are several geometric kernel manufacturers who have developed their own geometric modeling engines, but they are not compatible with other kernels, and need to use test tools and test cases (Python scripts) for function testing to perfect the kernel functions. The test tools need to be compatible with other kernels, and the test cases need to be widely applicable to multiple geometric modeling engines.

[0046] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below in combination with the drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0047] The current way of OCC (Open CASCADE) is name identification, which expands points, lines and surfaces through explode function, and then uses name identification. Other geometry modeling engine manufacturers mainly use the way of giving geometry elements an ID number, and each geometry element has a unique ID.

[0048] When querying the specified geometry element, the ID number binds the geometry element, and the ID number can be used for query and geometry operation. Taking a cuboid (named b) as an example, the OCC uses the name identification method by exploding b E (expanding the model b by edges), and then using b_1, b_2, b_3... to identify the edges; explode b F (expanding the model b by faces), and then using b_1, b_2, b_3... to identify the faces.

[0049] Other geometry modeling engines use the ID identification method: use numbers 1 to 12 to identify each edge of the cuboid, and 13 to 18 to identify each face of the cuboid. Different geometry elements are distinguished by the ID number, and the ID number is used for query and subsequent geometry operation.

[0050] However, in the case of unchanged test cases, due to the inconsistent topology of different kernels or inconsistent identification methods, the identification ID of the geometry element may also be inconsistent. The following shortcomings exist in using the identification ID to query the geometry element:

[0051] (1) Narrow scope of use cases: the method of using identification ID to query geometry elements cannot guarantee consistent identification methods under different kernels. For example, the ID of the bottom face of the cuboid is marked as 1 under A kernel, but it may be marked as 2 under B kernel, so that the test case cannot get consistent results, and the consistency of geometry operation cannot be guaranteed.

[0052] (2) Query results are not intuitive: since the rule of binding geometry elements by identification ID has been set and encapsulated in the kernel, users cannot know the logic of the geometry element identification ID method. For example, the user needs to perform geometry operation on the bottom face of the cuboid, but cannot confirm the serial number of the bottom face of the cuboid. In the process of "user input-kernel-entity topology", only using identification ID to query geometry elements, the query process is not clear, the query result is not intuitive, and it will cause trouble for subsequent geometry operation.

[0053] To solve this problem, the embodiment of the present application provides a method for querying geometric elements in different geometric modeling engines; the method can provide an interactive interface with a UV parameterization plane of an entity model for a user, and the user can select a point near a geometric element to be operated by operating the interactive interface, and map the point to a corresponding geometric element through a corresponding coordinate, so that the problems such as narrow use case range and non-intuitive query result caused by different identification methods in different geometric modeling engines can be avoided when the geometric element is queried by using an identification ID. Specifically, refer to Figure 1 FIG. 1 shows a step flowchart of the method for querying geometric elements in different geometric modeling engines according to an embodiment of the present application.

[0054] As shown in Figure 1 , the method for querying geometric elements in different geometric modeling engines can include the following steps:

[0055] Step 101, in response to a first user operation, determining a target positioning UV parameter point coordinate from a UV parameterization plane.

[0056] For an entity model, it can be mapped to a UV parameterization plane. Grid parameterization expands the surface of the entity model to a two-dimensional plane and assigns UV parameter point coordinates.

[0057] The UV parameter point coordinate can be a texture mapping coordinate. U can represent a horizontal direction (similar to an X axis); V can represent a vertical direction (similar to a Y axis), and these coordinates uniquely correspond to a three-dimensional point coordinate of the surface of the entity model and maintain the topological information of the entity model.

[0058] By constructing a mapping function f: (x, y, z)→(u, v) between the three-dimensional entity model and the two-dimensional UV parameterization plane, the three-dimensional coordinate point can be uniquely represented by the two-dimensional UV parameter point.

[0059] For a geometric element in an entity model, there is a UV parameter range, and a parameter point uniquely corresponds to a three-dimensional point coordinate of the entity model. Based on this, the user can perform a first user operation on the UV parameterization plane of the entity model displayed in the interactive interface, and the first user operation can be a selection operation, a click operation, etc. of a mouse, and the embodiment of the present application does not limit this.

[0060] After the user performs the first user operation, the point to which the first user operation is directed can be determined in response to the first user operation, and the position of the point in the UV parameterization plane can be determined; then, the target positioning UV parameter point coordinate corresponding to the position in the UV parameterization plane can be determined, that is, the coordinate of the position in the UV parameterization plane.

[0061] Step 102, determining a target geometric element from the solid model according to the target positioning UV parameter point coordinate.

[0062] After the target positioning UV parameter point coordinate is determined, a target geometric element associated with the target positioning UV parameter point coordinate can be determined from the solid model; for example, the geometric element closest to the target positioning UV parameter point coordinate can be determined as the target geometric element.

[0063] Step 103, determining a target geometric modeling engine currently loading the solid model, and determining target identification information of the target geometric element in the target geometric modeling engine.

[0064] Next, the target geometric modeling engine currently loading the solid model can be determined, and the target identification information of the target geometric element in the target geometric modeling engine can be determined; it should be noted that the identification manners of different geometric modeling engines are different, and thus the target identification information determined can be different when the target geometric modeling engine is different. The target identification information currently determined is only applicable to the target geometric modeling engine.

[0065] In addition, the positioning UV parameter point coordinates corresponding to each geometric element are fixed and do not change due to different geometric modeling engines; thus, the target positioning UV parameter point coordinate currently determined can be applicable to any geometric modeling engine, and the embodiments of the present application do not limit this.

[0066] In the embodiments of the present application, the target positioning UV parameter point coordinate is determined from the UV parameterization plane in response to the first user operation; the target geometric element is determined from the solid model according to the target positioning UV parameter point coordinate; and the target geometric modeling engine currently loading the solid model is determined, and the target identification information of the target geometric element in the target geometric modeling engine is determined. Through the embodiments of the present application, the user can select a point near the geometric element to be operated by operating the interactive interface, and the point can be mapped to the corresponding geometric element through the coordinate of the point, which can avoid problems such as narrow use case scope and non-intuitive query result caused by different identification manners in different geometric modeling engines.

[0067] Referring to Figure 2 , another step flowchart of a method for querying a geometric element in different geometric modeling engines according to an embodiment of the present application is shown, which can include the following steps:

[0068] Step 201, determining a target positioning UV parameter point coordinate from the UV parameterization plane in response to a first user operation.

[0069] After the user performs the first user operation, the point targeted by the first user operation can be determined in response to the first user operation, and the position of the point in the UV parameter plane can be determined; then, the target positioning UV parameter point coordinate corresponding to the position in the UV parameter plane can be determined.

[0070] Step 202, calculate the distance value of each geometric element in the entity model and the target positioning UV parameter point coordinate.

[0071] After the target positioning UV parameter point coordinate is determined, the distance value of the UV parameter point coordinate of each geometric element in the entity model and the target positioning UV parameter point coordinate can be calculated respectively; that is, the distance value of each geometric element in the entity model and the point selected by the user through the first user operation.

[0072] Step 203, determine the target geometric element from the geometric elements of the entity model according to the distance value of each geometric element and the target positioning UV parameter point coordinate.

[0073] After the distance value of the UV parameter point coordinate of each geometric element and the target positioning UV parameter point coordinate is determined, the unique target geometric element, that is, the geometric element that the user needs to operate, can be determined from the multiple geometric elements of the entity model according to the distance value of the UV parameter point coordinate of each geometric element and the target positioning UV parameter point coordinate.

[0074] In an embodiment of the present application, step 203 can be implemented through the following sub-steps:

[0075] Sub-step 11, determine the geometric element corresponding to the smallest distance value.

[0076] In some feasible embodiments, after the distance value of the UV parameter point coordinate of each geometric element and the target positioning UV parameter point coordinate is determined, the smallest distance value can be determined from the distance values, and the geometric element corresponding to the smallest distance value can be determined.

[0077] Sub-step 12, take the geometric element corresponding to the smallest distance value as the target geometric element.

[0078] After the smallest distance value is determined, the geometric element corresponding to the smallest distance value can be taken as the target geometric element, that is, the geometric element that the user wants to select through the first user operation.

[0079] In an embodiment of the present application, on the basis of step 203, the following steps can also be included:

[0080] When the geometric element corresponding to the smallest distance value includes at least two, the user is prompted to re-perform the first user operation.

[0081] In some possible embodiments, if the minimum distance value corresponds to more than one geometric element, i.e., the minimum distance value corresponds to at least two geometric elements, the user can be prompted to re-perform the first user operation to re-select a point in the UV parameter plane. The prompt can be a text prompt, for example: the target geometric element includes multiple, please reselect. Alternatively, it can also be an error prompt, for example: selection error, please reselect, and the embodiments of the present application do not limit this.

[0082] In step 204, the target geometric modeling engine currently loading the entity model is determined, and target identification information of the target geometric element in the target geometric modeling engine is determined.

[0083] Next, the target geometric modeling engine currently loading the entity model can be determined, and target identification information of the target geometric element in the target geometric modeling engine can be determined; it should be noted that since the identification methods of different geometric modeling engines are different, the target identification information determined can be different when the target geometric modeling engine is different. The target identification information currently determined is only applicable to the current target geometric modeling engine.

[0084] In addition, since the positioning UV parameter point coordinates corresponding to each geometric element are fixed and do not change due to different geometric modeling engines, the target positioning UV parameter point coordinates currently determined can be applicable to any geometric modeling engine, and the embodiments of the present application do not limit this.

[0085] In an embodiment of the present application, the above method can further include the following steps:

[0086] After the target geometric element is determined, the target geometric element is highlighted.

[0087] In some possible embodiments, after the target geometric element is determined, the target geometric element can be highlighted to determine whether it is the geometric element that the user wants to select.

[0088] If the target geometric element is not the geometric element that the user wants to select, the user can re-perform the first user operation, and the embodiments of the present application do not limit this.

[0089] In an embodiment of the present application, the above method can further include the following steps:

[0090] According to the target identification information, the target geometric element is extracted; and a target interface is called to perform a geometric operation on the target geometric element.

[0091] In some possible embodiments, after the target geometric element is determined, the user can perform a geometric operation on the target geometric element; for example, the target geometric element can be extracted from the solid model according to the target identification information.

[0092] Then, the relevant target interface can be called to perform a geometric operation on the target geometric element. The geometric operation can include any of the following:

[0093] Chamfering operation, offset operation, and tilting operation.

[0094] In actual applications, the edge / face serial number (i.e., target identification information) obtained from the parameter point is subjected to a geometric operation, such as chamfering, offsetting, and tilting. For example, in the chamfering example, an array can be used to store the obtained edge serial number (i.e., target identification information), and the relevant parameters of the chamfering function are input to call the relevant target interface to perform a chamfering operation on the target geometric element.

[0095] For example, the FindEdgeByNearestPoint function can be used to return the target identification information of the nearest geometric element according to the entity name of the solid model and the target positioning UV parameter point coordinates. The input parameters are the entity name and the target positioning UV parameter point coordinates, and the output result is the target identification information.

[0096] The required geometric element is queried by finding a parameter point of the geometric element and then matching the parameter point to the solid model. Because the point coordinates are unique under different kernels, the coordinate point corresponding to the parameter point is also unique, and the process of finding the desired geometric element by using the parameterized point is also uniquely determined, thereby constructing a technical solution for the consistency and accuracy of subsequent operations on geometric elements.

[0097] As shown in Figure 3

[0098] (1) Selecting a UV parameter point

[0099] For a geometric element in a geometric shape, there is a UV parameter range, and a parameter point uniquely corresponds to a target positioning UV parameter point coordinate of the solid model. The user can freely select a parameter point to query the geometric element, but needs to satisfy that the parameter point is closest to the required positioning edge / face.

[0100] ​As for a cuboid model a, the user wants to get two specific edges to perform chamfering operation, assuming the required edge identification number is [11, 13], the user needs to obtain this identification number by parameter point acquisition instead of directly using the serial number [11, 13], because the serial number of the selected two edges of the test case may be other numbers under other kernels. The user first selects two positioning UV parameter points on the two edges in a visual interface and mouse click manner, assuming that the target positioning UV parameter point coordinates corresponding to the two positioning UV parameter points are (0.1, 0.1) and (0.2, 0.3), and the selection of the parameter points only needs to satisfy the nearest distance to the required positioning edge / face.

[0101] (2) Compare the nearest geometric elements with the UV parameter points

[0102] The FindEdgeByNearestPoint / FindFaceByNearestPoint function can be used to return the serial number of the edge / face closest to the parameter point, and the serial number is obtained by spatial point and does not depend on the identification rule.

[0103] As the input cuboid name a and the value of the UV parameter point, the FindEdgeByNearestPoint function can be used to output the edge serial number under the kernel.

[0104] For the edge serial number obtained by the parameter point, it can be intuitively seen whether it is the object to be operated. If the three-dimensional coordinates corresponding to the parameter point are obviously far away from the selected edge, it can be considered that the parameter point is selected incorrectly, and the parameter point needs to be selected again.

[0105] (3) Extract geometric elements and perform related geometric operations

[0106] For the edge / face serial number obtained by the parameter point, perform geometric operations such as chamfering, offsetting, and tilting.

[0107] As shown in FIG. 8, after selecting the edge [11, 13], the chamfering operation can be performed. Figure 4

[0108] ​In the embodiment of the present application, in response to a first user operation, a target positioning UV parameter point coordinate is determined from a UV parameterization plane; a distance value of each geometric element in the solid model and the target positioning UV parameter point coordinate is calculated; a target geometric element is determined from the geometric elements of the solid model according to the distance value of each geometric element and the target positioning UV parameter point coordinate; a target geometric modeling engine of the currently loaded solid model is determined, and target identification information of the target geometric element in the target geometric modeling engine is determined. Through the embodiment of the present application, the user can select a point near the geometric element to be operated by operating the interactive interface, and map the point to the corresponding geometric element through the corresponding coordinate of the point, which can avoid problems such as narrow use case scope and non-intuitive query result caused by different identification methods in different geometric modeling engines.

[0109] Specifically, compared with the identification ID binding geometric element method which is only applicable to a single geometric kernel, the UV parameter point coordinate is more widely applicable to different geometric kernels. Through the parameterization representation of the model, for a specified UV parameter point coordinate, its position in the model is fixed and unique. This method can accurately locate the geometric element in solid modeling and geometric operation, and maintain the consistency of the geometric element and the stability of the geometric operation.

[0110] In addition, compared with the identification ID method, the UV parameter point coordinate query can more clearly and intuitively show the positional relationship with the geometric element. By establishing a clear connection process of "user input-kernel-solid topology", the user can accurately locate the required geometric element, and directly see the query result in the view. If the UV parameter point coordinate does not match the geometric element that the user wants, it can be clearly known that the parameter point is selected abnormally, and the parameter point needs to be selected again.

[0111] It should be noted that, for the method embodiments, in order to simply describe, they are all expressed as a series of action combinations, but those skilled in the art should know that the embodiments of the present application are not limited by the order of the described actions, because according to the embodiments of the present application, certain steps can be performed in other order or at the same time. Secondly, those skilled in the art should know that the embodiments described in the specification all belong to preferred embodiments, and the actions involved are not necessarily required by the embodiments of the present application.
