Abstract

The application discloses a building block linkage rotation method and device, a terminal equipment and a storage medium. After a user selects a target building block and a target rotation axis, the target building block is taken as an initial node to traverse a connection graph. In the process of traversing the connection graph, it is determined whether there is a connection edge in all connection edges of the current node, the axis line of which is on the same axis line as the target rotation axis, the connection mode is shaft hole coupling, and the shaft hole is a cross shaft hole without pin hole restriction. If so, the building block corresponding to the current node is added to a linkage rotation set, then another node corresponding to the current connection edge is taken as a node for the next time of traversal, and then the linkage relationship is diffused to the next node. Finally, when the target building block is controlled to rotate around the target rotation axis, each building block in the linkage rotation set is synchronously controlled to rotate. Through implementation of the above scheme of the application, the associated building blocks can be driven to rotate together when the target building block is controlled to rotate, and the simulation effect of virtual building block building is improved.

Description

Technical Field

[0001] This invention relates to the field of digital model building, and in particular to a method, apparatus, terminal device, and storage medium for the linkage and rotation of building blocks. Background Technology

[0002] RoboBuilder is a platform for building block creations, allowing users to design and create models, mechanical structures, and dynamic shapes by assembling various block components.

[0003] In the existing solution, when the user selects a block and the target rotation axis to rotate, only the individual block can be controlled to rotate independently. However, in the actual physical scene, there are connections between blocks. The rotation of one block often causes other related blocks to rotate in tandem. The existing block building platform cannot simulate the above-mentioned linkage rotation effect, and the simulation effect of virtual block building is poor. Summary of the Invention

[0004] This invention provides a method, apparatus, terminal device, and storage medium for the linkage and rotation of building blocks, which can improve the simulation level of virtual building block construction.

[0005] An embodiment of the present invention provides a method for the coordinated rotation of building blocks, comprising: In the current block-building scenario, respond to the user's selected operation and determine the target block and the target rotation axis; Starting with the target block as the initial node, the connection graph corresponding to the current block building scene is traversed. Specifically, each block physically connected in the current block building scene is used as a node. A connection edge is constructed between any two physically connected blocks. The region corresponding to the connection point of each block is used as the feature region of each block. For each connection edge, the feature type, axis, pivot point, and connection mode between the two feature regions corresponding to the two ends of the connection edge are used as the edge attributes. The connection graph is constructed based on the nodes, the connection edges between nodes, and the corresponding edge attributes. During each traversal, obtain all current connected edges corresponding to the current node. For each current connected edge, determine the axis of the current connected edge based on the axis and axis point in the edge attribute. If it is determined that the axis of the current connection edge is on the same axis as the axis of the target rotation axis, the connection mode corresponding to the current connection edge is shaft-hole coupling, and the shaft hole is a cross shaft hole without pin hole restriction, the current block corresponding to the current node is added to the linkage rotation set, and the other node corresponding to the current connection edge is used as the node for the next traversal. Based on the linkage rotation set, when the target block rotates around the target rotation axis, the other related blocks in the linkage rotation set are controlled to rotate synchronously.

[0006] Furthermore, it also includes: during each traversal, when it is determined that the axis of the current connecting edge is not on the same axis as the axis of the target rotation axis, the current block corresponding to the current node is added to the linkage rotation set, and the other node corresponding to the current connecting edge is used as the node for the next traversal.

[0007] Furthermore, during each traversal, if it is determined that the axis of the current connecting edge is on the same axis as the axis of the target rotation axis, and the connection mode corresponding to the current connecting edge is pin-hole coupling, the current block corresponding to the current node is added to the linkage rotation set, the current connecting edge is used as a blocking edge, and the block corresponding to the other node of the current connecting edge is used as a non-associated rotation block and is not added to the linkage rotation set.

[0008] Furthermore, it also includes: during each traversal, if it is determined that the axis of the current connecting edge is on the same axis as the target rotation axis and the connection mode corresponding to the current connecting edge is not axis-hole coupling or pin-hole coupling, it is determined whether the axis point of the current connecting edge coincides with the axis point of the target rotation axis; if so, the current block corresponding to the current node is added to the linkage rotation set, the current connecting edge is used as a blocking edge, and the block corresponding to the other node of the current connecting edge is used as a non-associated rotation block and is not added to the linkage rotation set; if not, the current block corresponding to the current node is added to the linkage rotation set, and the other node corresponding to the current connecting edge is used as the node for the next traversal.

[0009] Based on the above method embodiments, the present invention provides corresponding apparatus embodiments; One embodiment of the present invention provides a block linkage rotation device, including: a target selection module, a connection diagram traversal module, an axis determination module, a linkage rotation set generation module, and a rotation control module; The target selection module is used to respond to the user's selection operation in the current block building scenario and determine the target block and the target rotation axis. The connection graph traversal module is used to traverse the connection graph corresponding to the current block building scene, with the target block as the initial node. Specifically, it uses each block physically connected in the current block building scene as a node, constructs a connection edge between any two physically connected blocks, and uses the region corresponding to the connection point of each block as the feature region of each block. For each connection edge, the feature type, axis, pivot point, and connection mode between the two feature regions corresponding to the two ends of the connection edge are used as the edge attributes. The connection graph is constructed based on the nodes, the connection edges between nodes, and the corresponding edge attributes. The axis determination module is used to obtain all current connected edges corresponding to the current node during each traversal. For each current connected edge, the axis of the current connected edge is determined according to the axis and axis point in the edge attribute. The linkage rotation set generation module is used to add the current block corresponding to the current node to the linkage rotation set when it is determined that the axis of the current connection edge and the axis of the target rotation axis are on the same axis, the connection mode corresponding to the current connection edge is shaft hole coupling, and the shaft hole is a cross shaft hole without pin hole restriction. The module also uses the other node corresponding to the current connection edge as the node for the next traversal. The rotation control module is used to control the other associated blocks in the linkage rotation set to rotate synchronously when the target block rotates around the target rotation axis, according to the linkage rotation set.

[0010] Furthermore, the linkage rotation set generation module is also used to add the current block corresponding to the current node to the linkage rotation set when it is determined that the axis of the current connecting edge and the axis of the target rotation axis are not on the same axis during each traversal, and to use the other node corresponding to the current connecting edge as the node for the next traversal.

[0011] Furthermore, the linkage rotation set generation module is also used to, during each traversal, if it is determined that the axis of the current connecting edge and the axis of the target rotation axis are on the same axis, and the connection mode corresponding to the current connecting edge is pin-hole coupling, add the current block corresponding to the current node to the linkage rotation set, treat the current connecting edge as a blocking edge, and treat the block corresponding to the other node of the current connecting edge as a non-associated rotation block, and not add it to the linkage rotation set.

[0012] Furthermore, the linkage rotation set generation module is also used during traversal to determine whether the axis point of the current connecting edge coincides with the axis point of the target rotation axis, provided that the axis of the current connecting edge is on the same axis as the target rotation axis and the connection mode corresponding to the current connecting edge is not axis-hole coupling or pin-hole coupling. If yes, the current block corresponding to the current node is added to the linkage rotation set, the current connecting edge is used as a blocking edge, and the block corresponding to the other node of the current connecting edge is used as a non-associated rotation block and is not added to the linkage rotation set. If no, the current block corresponding to the current node is added to the linkage rotation set, and the other node corresponding to the current connecting edge is used as the node for the next traversal.

[0013] Based on the above method embodiments, the present invention provides a corresponding terminal device embodiment; The present invention provides a terminal device, including a processor, a memory, and a computer program stored in the memory and configured to be executed by the processor. When the processor executes the computer program, it implements a block linkage rotation method described in any embodiment of the present invention.

[0014] Based on the above method embodiments, the present invention provides a corresponding storage medium embodiment; The present invention provides a storage medium including a processor, a memory, and a computer program stored in the memory and configured to be executed by the processor. When the processor executes the computer program, it implements a block linkage rotation method described in any embodiment of the present invention.

[0015] The embodiments of the present invention have the following beneficial effects: This invention provides a method, apparatus, terminal device, and storage medium for linked rotation of building blocks. The method, after the user selects a target building block and a target rotation axis, traverses the corresponding connection graph using the target building block as the initial node. During the traversal, it determines whether any of the connecting edges of the current node have an axis that is on the same axis as the target rotation axis, and the corresponding connection mode is a shaft-hole coupling connection with a cross-shaped shaft hole without pin hole restrictions. If such an edge exists, it indicates that the building blocks corresponding to the nodes at both ends of this connecting edge are permanently connected; rotation of one edge inevitably causes rotation of the other. In this case, the building block corresponding to the current node is added to the linked rotation set as a building block that can rotate with the target building block. Then, adjacent building blocks connected to the current building block via corresponding connecting edges are used as nodes for the next traversal, thus extending the linkage determination to the next node. After traversing the connection graph, while controlling the target building block to rotate around the target rotation axis, the rotation of each building block in the final generated linked rotation set is synchronously controlled. By implementing the above-mentioned solution of the present invention, the associated blocks that will rotate together with the target block when the target block rotates around the target rotation axis can be determined according to the selected target block and the target rotation axis. When controlling the rotation of the target block, the associated blocks will be driven to rotate together, thereby improving the simulation effect of virtual block building.

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0028] See Figure 1 An embodiment of the present invention provides a method for the linked rotation of building blocks, comprising: Step S101: In the current block building scenario, respond to the user's selection operation for blocks and rotation axes, and determine the target block and the target rotation axis; Indicative, such as Figure 2 As shown, in this invention, a virtual block building interface 1 is generated. The virtual block building interface 1 displays the blocks that exist in the current block building scene. The user selects the corresponding block to be rotated and the rotation axis on the virtual block building interface 1 with the mouse, thereby determining the target block 11 and the target rotation axis 12.

[0029] Step S102: Using the target block as the initial node, traverse the connection graph corresponding to the current block building scene; wherein, using each block that has a physical connection in the current block building scene as a node, construct a connection edge between any two blocks that have a physical connection, and use the area corresponding to the connection point of each block as the feature area of ​​each block. For each connection edge, use the axis, pivot point, and connection mode between the two feature areas corresponding to the two ends of the connection edge as the edge attributes of the connection edge; construct the connection graph based on the nodes, the connection edges between nodes, and the corresponding edge attributes.

[0030] First, the construction of the connection diagram needs to be explained. In one embodiment of this invention, the connection diagram can be pre-configured and constructed by the user. Specifically, based on the actual connection relationship of each block in the current block-building scenario, with each block as a node, corresponding edges are constructed between the nodes corresponding to blocks with physical connections to form the aforementioned connection diagram. Each block has various regions, and the region where one block connects to another is defined as a feature region. In actual scenarios, the region where one block connects to another is generally a characteristic hole, shaft, pin, etc. These regions correspond to axes, and the axes of two interconnected feature regions are consistent. The axis points and axes of the feature regions can be determined in advance as edge attributes of the connection edges. At the same time, the connection mode and feature region type are also used as edge attributes of the aforementioned edges. The aforementioned feature region types include, for example: shaft, shaft hole, pin, pin hole, turntable top, turntable bottom, track shaft, track hole, etc. The connection between shafts and shaft holes forms a shaft hole coupling connection mode, and the connection between pins and pin holes forms a pin hole coupling connection mode. In this invention, for each feature region, a data object is configured with data including direction (e.g., a pin is inserted into a hole with a single opening, and can only be inserted from one side of the opening; the direction of this insertion is the direction of the feature region, i.e., the aforementioned axial direction), type, size, etc. The data is pre-configured and stored in a configuration file, and is used as an edge attribute of the connection edge when constructing the connection diagram. This data object contains data indicating the construction direction of the feature region.

[0031] Step S103: During each traversal, obtain all current connecting edges corresponding to the current node. For each current connecting edge, determine the axis of the current connecting edge based on the axis and axis point in the edge attributes. Specifically, the traversal begins with the target block as the initial node. During the first traversal, the current node is the node corresponding to the target block. For the current node, all connecting edges corresponding to the current node are extracted according to the connection graph to obtain several current connecting edges. Then, for each connecting edge, the axis of the current connecting edge can be determined according to the axial direction and axis point coordinates of any one of the two feature regions in the edge attribute.

[0032] Step S104: If it is determined that the axis of the current connection edge and the axis of the target rotation axis are on the same axis, the connection mode corresponding to the current connection edge is shaft-hole coupling, and the shaft hole is a cross shaft hole without pin hole restriction, add the current block corresponding to the current node to the linkage rotation set, and take the other node corresponding to the current connection edge as the node for the next traversal. In a preferred embodiment, the method further includes: during each traversal, when it is determined that the axis of the current connecting edge is not on the same axis as the axis of the target rotation axis, adding the current block corresponding to the current node to the linked rotation set, and using the other node corresponding to the current connecting edge as the node for the next traversal.

[0033] In a preferred embodiment, the method further includes: during each traversal, if it is determined that the axis of the current connecting edge is on the same axis as the axis of the target rotation axis, and the connection mode corresponding to the current connecting edge is pin-hole coupling, the current block corresponding to the current node is added to the linkage rotation set, the current connecting edge is used as a blocking edge, and the block corresponding to the other node of the current connecting edge is used as a non-associated rotation block and is not added to the linkage rotation set.

[0034] In a preferred embodiment, the method further includes: during each traversal, if it is determined that the axis of the current connecting edge is on the same axis as the target rotation axis and the connection mode corresponding to the current connecting edge is not shaft-hole coupling or pin-hole coupling, determining whether the axis point of the current connecting edge coincides with the axis point of the target rotation axis; if so, adding the current block corresponding to the current node to the linkage rotation set, using the current connecting edge as a blocking edge, and using the block corresponding to the other node of the current connecting edge as a non-associated rotation block, not adding it to the linkage rotation set; if not, adding the current block corresponding to the current node to the linkage rotation set, and using the other node corresponding to the current connecting edge as the node for the next traversal.

[0035] Specifically, the generation of linked rotation sets depends on the determination of rotational associations. In practice, this determination is made according to the following process: First, determine whether the axis of the current connecting edge and the axis of the target rotation axis are on the same axis. If they are not on the same axis, then allow this rotation relationship to continue to propagate along the connecting edge to the adjacent block (i.e., the other node corresponding to the current connecting edge besides the current node). Use this adjacent block as the node for the next traversal, and add the current node to the linked rotation set. If they are on the same axis, then the connection mode of the current connecting edge and the feature point types at both ends are further read.

[0036] If the current connecting edge corresponds to a pin and a pin hole connection, i.e., the pin hole coupling mode mentioned above, the current connecting edge is identified as a blocking edge. Then, the current block corresponding to the current node is added to the linkage rotation set, and the rotation relationship is no longer propagated across this edge.

[0037] If the current connecting edge corresponds to a shaft and a hole, i.e., in the aforementioned shaft-hole coupling mode, check whether the shaft hole is a cross-shaped shaft hole and whether the hole position also has a pin-hole type restriction feature. If the shaft hole is a pure cross-shaped shaft hole without pin-hole restriction, then it is allowed to continue propagating across the connecting edge to the adjacent block, and this adjacent block is used as the node for the next traversal. At the same time, the current node is added to the linkage rotation set; otherwise, the connecting edge is identified as a blocking edge, and then the current block corresponding to the current node is added to the linkage rotation set, and the rotation relationship is no longer propagated across the edge.

[0038] If the current connecting edge belongs to other connection types, such as the connection between the top and bottom of the turntable, it is determined whether the axis point of the connecting edge coincides with the axis point of the target rotation axis. If they coincide, the connecting edge is identified as a blocking edge; if they do not coincide, the rotation relationship is allowed to be propagated to the next adjacent block.

[0039] Using the above method, all blocks that are allowed to be reached through propagation are added to the linked rotation set until the traversal is complete. The linked block set corresponding to the target rotation axis is output and used for subsequent single-axis rotation control.

[0040] Step S105: According to the linkage rotation set, when the target block rotates around the target rotation axis, control the other related blocks in the linkage rotation set to rotate synchronously.

[0041] Indicative, such as Figure 3 As shown, assuming that the linked block 13 is within the linked rotation set, when the target block 11 is rotated around the target rotation axis 12, the linked block 13 will also rotate along with it, forming... Figure 3 The effect shown is due to Figure 3 and Figure 2 The comparison shows that when the target block 11 rotates, the position of the linked block 13 also moves, thus achieving the effect of rotating the target block and driving the associated blocks to rotate together, which improves the simulation effect of virtual block building.

[0042] like Figure 4 As shown, one embodiment of the present invention provides a block linkage rotation device, comprising: The module includes a target selection module, a connection graph traversal module, an axis determination module, a linkage rotation set generation module, and a rotation control module. The target selection module is used to respond to the user's selection operation in the current block building scenario and determine the target block and the target rotation axis. The connection graph traversal module is used to traverse the connection graph corresponding to the current block building scene, with the target block as the initial node. Specifically, it uses each block physically connected in the current block building scene as a node, constructs a connection edge between any two physically connected blocks, and uses the region corresponding to the connection point of each block as the feature region of each block. For each connection edge, the feature type, axis, pivot point, and connection mode between the two feature regions corresponding to the two ends of the connection edge are used as the edge attributes. The connection graph is constructed based on the nodes, the connection edges between nodes, and the corresponding edge attributes. The axis determination module is used to obtain all current connected edges corresponding to the current node during each traversal. For each current connected edge, the axis of the current connected edge is determined according to the axis and axis point in the edge attribute. The linkage rotation set generation module is used to add the current block corresponding to the current node to the linkage rotation set when it is determined that the axis of the current connection edge and the axis of the target rotation axis are on the same axis, the connection mode corresponding to the current connection edge is shaft hole coupling, and the shaft hole is a cross shaft hole without pin hole restriction. The module also uses the other node corresponding to the current connection edge as the node for the next traversal. The rotation control module is used to control the other associated blocks in the linkage rotation set to rotate synchronously when the target block rotates around the target rotation axis, according to the linkage rotation set.

[0043] In a preferred embodiment, the linkage rotation set generation module is further configured to, during each traversal, add the current block corresponding to the current node to the linkage rotation set when it is determined that the axis of the current connecting edge and the axis of the target rotation axis are not on the same axis, and use the other node corresponding to the current connecting edge as the node for the next traversal.

[0044] In a preferred embodiment, the linkage rotation set generation module is further configured to, during each traversal, if it is determined that the axis of the current connecting edge and the axis of the target rotation axis are on the same axis, and the connection mode corresponding to the current connecting edge is pin-hole coupling, add the current block corresponding to the current node to the linkage rotation set, treat the current connecting edge as a blocking edge, and treat the block corresponding to the other node of the current connecting edge as a non-associated rotation block, and not add it to the linkage rotation set.

[0045] In a preferred embodiment, the linkage rotation set generation module is further configured to, during traversal, determine whether the axis point of the current connecting edge coincides with the axis point of the target rotation axis if it is determined that the axis of the current connecting edge is on the same axis as the target rotation axis and the connection mode corresponding to the current connecting edge is not axis-hole coupling or pin-hole coupling; if yes, add the current block corresponding to the current node to the linkage rotation set, use the current connecting edge as a blocking edge, and use the block corresponding to the other node of the current connecting edge as a non-associated rotation block, not adding it to the linkage rotation set; if no, add the current block corresponding to the current node to the linkage rotation set, and use the other node corresponding to the current connecting edge as the node for the next traversal.

Specifically, it uses each block physically connected in the current block building scene as a node, constructs a connection edge between any two physically connected blocks, and uses the region corresponding to the connection point of each block as the feature region of each block. For each connection edge, the axis, pivot point, and connection pattern between the two feature regions corresponding to the two ends of the connection edge are used as the edge attributes of the connection edge. The connection graph is constructed based on the nodes, the connection edges between nodes, and the corresponding edge attributes. The axis determination module is used to obtain all current connected edges corresponding to the current node during each traversal. For each current connected edge, the axis of the current connected edge is determined according to the axis and axis point in the edge attribute. The linkage rotation set generation module is used to add the current block corresponding to the current node to the linkage rotation set when it is determined that the axis of the current connection edge and the axis of the target rotation axis are on the same axis, the connection mode corresponding to the current connection edge is shaft hole coupling, and the shaft hole is a cross shaft hole without pin hole restriction. The module also uses the other node corresponding to the current connection edge as the node for the next traversal. The rotation control module is used to control the other associated blocks in the linkage rotation set to rotate synchronously when the target block rotates around the target rotation axis, according to the linkage rotation set.

The block linkage rotation device as described in claim 5, characterized in that, The linked rotation set generation module is also used to add the current block corresponding to the current node to the linked rotation set when it is determined that the axis of the current connecting edge and the axis of the target rotation axis are not on the same axis during each traversal, and to use the other node corresponding to the current connecting edge as the node for the next traversal.

7. The block linkage rotation device as described in claim 6, characterized in that, The linkage rotation set generation module is also used to, during each traversal, if it is determined that the axis of the current connecting edge and the axis of the target rotation axis are on the same axis, and the connection mode corresponding to the current connecting edge is pin-hole coupling, add the current block corresponding to the current node to the linkage rotation set, treat the current connecting edge as a blocking edge, and treat the block corresponding to the other node of the current connecting edge as a non-associated rotation block, and not add it to the linkage rotation set.

8. The block linkage rotation device as described in claim 6, characterized in that, The linkage rotation set generation module is also used, during traversal, to determine whether the axis point of the current connecting edge coincides with the axis point of the target rotation axis, provided that the axis of the current connecting edge is on the same axis as the target rotation axis and the connection mode corresponding to the current connecting edge is not axis-hole coupling or pin-hole coupling. If yes, the current block corresponding to the current node is added to the linkage rotation set, the current connecting edge is used as a blocking edge, and the block corresponding to the other node of the current connecting edge is used as a non-associated rotation block and is not added to the linkage rotation set. If no, the current block corresponding to the current node is added to the linkage rotation set, and the other node corresponding to the current connecting edge is used as the node for the next traversal.
