Description

Technical Field

[0001] The present application relates to the field of model design, and in particular to a method for distinguishing interconnected pipelines, an electronic device, and a readable storage medium. Background Art

[0002] The manufacturing industry, especially the mold-related industry, requires the use of 3D design software (such as UGNX) to design 3D models. Most 3D models contain pipes, such as water pipes, gas pipes or oil pipes. Pipelines are usually intricate and it is difficult to distinguish whether the design has errors or omissions with the naked eye, so designers usually paint different interconnected pipes with different colors to distinguish the interconnected pipes, thereby troubleshooting abnormalities such as pipe errors and omissions. However, the coloring function of UGNX in the prior art can only modify the color of one pipe surface at a time. When the model is more complex, there are as many as thousands of pipe surfaces that need to be colored. Therefore, designers need to repeat the operation thousands of times. Repeating the same coloring action is extremely time-consuming, which greatly increases the design cost of the 3D model.

[0003] Therefore, a method is needed to automatically select and distinguish interconnected pipes from a three-dimensional model. Summary of the invention

[0049] Embodiment 1

[0050] Three-dimensional model design usually involves distinguishing interconnected pipes. Manually searching for and distinguishing interconnected pipes takes a lot of time, making the design efficiency of the three-dimensional model low.

[0051] In view of the above problems, the present application embodiment provides a method for distinguishing interlinked pipes. Figure 1 and Figure 3 , Figure 1 is a flow chart of a method for distinguishing interconnected pipes according to an embodiment of the present application. Figure 3 It is a schematic diagram of the structure of the interconnected pipelines shown in the embodiment of the present application. Figure 3 There are two interconnected pipes, namely interconnected pipe 1 and interconnected pipe 2. The two interconnected pipes are independent of each other and cannot be connected by any cylindrical surface.

[0052] The specific method of distinguishing the interconnected pipelines is as follows:

[0053] A1. Obtain all face identifiers of the target model body.

[0054] All face identifiers of the target model body are obtained. For example, the target model body has k face identifiers in total. The same pipeline identification method needs to be looped k times, and the current loop number d is set to 0.

[0055] A2. Determine whether all model faces of the target model body have been traversed.

[0056] Add 1 to the current loop number d, d=d+1. Determine whether the current loop number d is greater than k. If so, execute A8, if not, execute A3.

[0057] A3. Determine whether the current surface is a cylindrical surface.

[0058] The current surface S corresponding to the current cycle number d d It may be a model surface randomly selected from the target model body, or it may be a model surface selected from the target model body in a fixed order, which depends on the actual situation and is not limited here.

[0059] When d=1, the current surface S1 is the initial surface.

[0060] Determine whether the current surface is a cylindrical surface. If so, execute A4; if not, return to A2.

[0061] A4. Determine whether the current surface identifier already exists in the connected waterway identifier set.

[0062] Determine the current face S d Whether the surface identifier of S already exists in the connected waterway identifier set. If so, it means that the current surface S d If it has been traversed, there is no need to traverse it again, and the process returns to A2. If not, the process goes to A5.

[0063] A5. Traverse the connected pipelines on the current page.

[0064] Traverse the current face S d All M model edges of the traversed edge identifier set are added to the traversed edge identifier set. All S associated faces of the M model edges are traversed, and the face identifiers of the S associated faces are added to the traversed face identifier set.

[0065] For example, the current surface S1 is traversed through the interconnected pipelines to obtain associated surfaces S3, S5, and S7.

[0066] A6. Add the traversed surface identifier set to the connected waterway identifier set.

[0067] The traversed surface identifier set is added to the connected waterway identifier set, the traversed surface identifier set newly added to the connected waterway identifier set is stored in an array, and marked in the connected waterway identifier set, to obtain an array Cd .

[0068] Exemplarily, the face identifiers of associated faces S3, S5 and S7 are added to the traversed face identifier set, the traversed face identifier set is added to the connected waterway identifier set, and the traversed face identifier set obtained in this cycle is marked as array C1 in the connected waterway identifier set, where C1 = {S1, S3, S5, S7}.

[0069] A7. Clear the traversed edge identifier set and the traversed face identifier set.

[0070] Clear the traversed edge identifier set and the traversed face identifier set to prevent them from affecting the next loop, and return to A2.

[0071] A8. End the method of distinguishing the connected pipelines.

[0072] In practical applications, interconnected pipes are connected through cylindrical surfaces. Therefore, the embodiment of the present application selects cylindrical surfaces in the target model body for traversal. During the traversal, the model edges associated with the cylindrical surfaces are selected for searching one by one. Since two unconnected pipes do not have associated model edges, a group of interconnected pipes can be accurately screened out when the traversal time is long enough. The connected waterway identifier set is marked to distinguish different connected pipes. Compared with manual search and distinction of connected pipes, the execution time is reduced, thereby improving the design efficiency of the target model body.

[0073] Embodiment 2

[0074] The connected pipeline traversal method traverses all model edges of the current face, and then traverses all model faces containing each model edge to obtain all model faces of a connected pipeline.

[0075] This application embodiment provides a method for traversing a similar pipeline. Figure 2 and Figure 4 , Figure 2 is a flow chart of a pipeline traversal method according to an embodiment of the present application. Figure 4 It is a schematic diagram of the structure of the model surface and model edge shown in the embodiment of the present application.

[0076] The specific method of traversing the same pipeline is as follows:

[0077] B1. Obtain all model edges of the current face according to the face identifier of the current face.

[0078] According to the current S d The identifier of the current face is used to obtain all model edges m, where m is an integer greater than 2, and the number of loops j=0.

[0079] When d=1, the current surface S1 is the initial surface; when d≠1, the current surface S d The associated face in the traversed face identifier set.

[0080] Exemplarily, the initial surface S1 is a cylindrical surface 2, the model edge 9, the model edge 10 and the model edge 11 of the cylindrical surface 2 are obtained, and the face identifier of the cylindrical surface 2 is added to the traversed face identifier set.

[0081] B2. Determine whether all model edges of the current face have been looped.

[0082] Let j=j+1, and determine whether j is greater than m. If yes, execute B10, if no, execute B3.

[0083] B3. Determine whether the edge identifier of the current edge exists in the traversed edge identifier set.

[0084] Determine whether the j-th model edge exists in the traversed edge identifier set. If yes, it means that the j-th model edge has been traversed, and return to B2. If no, it means that the j-th model edge needs to be traversed, and execute B4.

[0085] B4. Add the edge identifier of the current edge to the set of traversed edge identifiers.

[0086] Set the current face S d The edge identifier of the j-th model edge is added to the traversed edge identifier set to prevent subsequent loops from traversing this model edge again.

[0087] Exemplarily, the edge identifier of the current edge 10 is added to the set of traversed edge identifiers.

[0088] B5. Get all associated faces containing the current edge.

[0089] Get the total number n of associated faces containing the current j-th model edge, set the associated face loop identifier u to 0, and n to an integer greater than or equal to 1.

[0090] Exemplarily, the associated surface 7 and the associated surface 2 of the current edge 10 are obtained.

[0091] B6. Determine whether all associated faces of the current edge have been traversed.

[0092] Add 1 to the associated surface loop identifier, u=u+1, and determine whether the associated surface loop identifier u is greater than n. If so, it means that all associated surfaces containing the current edge have been traversed, and return to B2. If not, it means that other associated surfaces of the current edge need to be traversed, and execute B7.

[0093] For example, the association surface loop identifier is increased by 1, at which time u=1, n=2, and u<n. The first association surface, that is, association surface 7, is prepared to be traversed.

[0094] B7. Determine whether the associated surface is a cylindrical surface.

[0095] Determine whether the associated surface u is a cylindrical surface according to the surface identifier of the associated surface u. If yes, execute B8; if no, return to B6.

[0096] Exemplarily, the associated surface 7 is a cylindrical surface, and B8 is executed.

[0097] B8. Determine whether the associated surface has been traversed.

[0098] Check whether the face identifier of the associated face u exists in the traversed face identifier set and the connected waterway identifier set. If so, it means that the associated face u has been traversed, and execute B6. If not, it means that the associated face u has not been traversed, and execute B9.

[0099] Exemplarily, the face identifier of the associated face 7 does not exist in the traversed face identifier set and the connected waterway identifier set, indicating that the associated face 7 has not been traversed, and B9 is executed.

[0100] B9. Add the face identifier of the associated face to the traversed face identifier set.

[0101] Add the face identifier of the associated face u to the set of traversed face identifiers to prevent traversing the associated face u next time, and return to B6.

[0102] B10. Determine whether the execution time of the traversal of the same pipeline exceeds the preset screening time.

[0103] Determine whether the execution time of the same pipeline traversal exceeds the preset screening time. If yes, execute B12; if no, execute B11.

[0104] One cylindrical surface corresponds to only one interconnected pipeline. No matter how long it takes, it is impossible to traverse the interconnected pipeline from one cylindrical surface to another interconnected pipeline.

[0105] B11. Update the current page.

[0106] Update the current face using the cylindrical surface obtained from the traversed face identifier set and return B1.

[0107] For example, d=2, when the current face S d is S2.

[0108] B12. End the traversal of the connected pipelines.

[0109] An embodiment of the present application provides a method for traversing interconnected pipes, which obtains all model edges of the current face, traverses each untraversed model edge, traverses all model faces including the untraversed model edges, determines the face type and whether the face has been traversed for all model faces including the untraversed model edges, and adds the untraversed cylindrical surfaces to the traversed face identifier set. Through the interconnected pipe traversal, the entire interconnected pipe where the current face is located can be found, and the face identifiers of all model faces of the entire interconnected pipe can be stored. The interconnected pipe traversal can also prevent the re-traversal of the model edges or model faces that have been traversed, thereby reducing repeated operations and improving the efficiency of finding interconnected pipes.
