Description

Thinking guide drawing rendering method and device and electronic equipment

Technical Field

The present disclosure relates to the field of computer technologies, and in particular, to a method and an apparatus for rendering a mind map, and an electronic device.

Background

In modern society, people are faced with a vast amount of information and concepts, and there is a need for an efficient way to sort, connect and understand such information. The mind map provides a nonlinear mode, different ideas and information can be presented in a layering and visual mode, and people can quickly comb a large amount of information.

In general, mind map usually starts with a central topic or concept and then connects related subtopics, ideas and keywords through radial branches.

The starting point and each branch in the mind map can be summarized as each node in the mind map.

In the related art, if an object performs an adjustment operation on the mind map (for example, adding a new node, deleting a node, adding a mark to a node, and filtering a node), it is necessary to render based on each node description information corresponding to each node in the mind map.

In this way, in the rendering process, even if the object performs an adjustment operation for only one node in the mind map, the mind map needs to be rendered again based on the node description information corresponding to all the nodes in the mind map, where the node description information may include: coordinate information of nodes, attribute information of nodes, correspondence between nodes, priority information of nodes, and the like.

Therefore, when the number of nodes in the mind map is large, rendering is performed on all the nodes in the mind map, a large amount of data needs to be processed, and a long processing time needs to be consumed, so that the presentation efficiency of the mind map is reduced.

On the other hand, when the number of nodes in the mind map is large, the nodes are limited by data processing capability, and the phenomenon of jam is easy to cause in rendering, so that page jam for displaying the mind map is not available, and the use experience of an object is reduced.

The following briefly describes the design concept of the embodiment of the present application:

Therefore, in order to solve the above-mentioned problems, a method for rendering a mind map is provided in the embodiments of the present application, which is mainly aimed at obtaining an adjustment policy of at least one first node after a node adjustment operation is triggered on the mind map, selecting a reference node in the mind map, obtaining at least one target node and a corresponding adjustment result by traversing the reference node and corresponding descendant nodes, and re-rendering the mind map based on the adjustment result of the at least one target node to obtain an updated mind map.

Fig. 1 is a schematic diagram of an application scenario in an embodiment of the present application. The application scenario diagram includes a terminal device 10 and a server 11. The terminal device 10 and the server 11 may communicate with each other via a communication network.

In an alternative embodiment, the communication network may be a wired network or a wireless network, so that the terminal device 10 and the server 11 may be directly or indirectly connected through wired or wireless communication, and the embodiment of the present application is not limited herein specifically.

In the embodiment of the present application, the terminal device 10 is an electronic device used as an object, and the electronic device may be a mobile phone, a computer, an intelligent voice interaction device, an intelligent home, a vehicle-mounted terminal, an aircraft, and the like.

The server 11 may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing cloud services, cloud databases, cloud computing, cloud storage, cloud functions, network services, cloud communication, middleware services, domain name services, security services, a content delivery network (Content Delivery Network, CDN), basic cloud computing services such as big data and an artificial intelligent platform.

The rendering method of the mind map of the embodiment of the present application may be separately performed by the terminal device 10. When executed by the terminal device 10 alone, the terminal device 10 may perform a rendering method of the mind map to obtain an updated mind map.

The method for rendering the mind map provided by the exemplary embodiments of the present application will be described below with reference to the accompanying drawings in conjunction with the application scenarios described above, and it should be noted that the application scenarios described above are only shown for the convenience of understanding the spirit and principles of the present application, and the embodiments of the present application are not limited in any way in this respect.

Referring to fig. 2, a flowchart of an implementation of a method for rendering a mind map according to an embodiment of the present application is shown, where the implementation flow of the method is as follows:

step S201, presenting a thinking guide diagram;

the thinking guide graph comprises a plurality of nodes, each node represents a logic point in the thinking guide graph, and the hierarchical connection relation among the nodes represents logic association among the corresponding logic points;

it should be noted that, the mind map is a tree data structure, and there is only one root node, and other nodes belong to descendant nodes of the root node.

For example, as shown in fig. 3, if only node 1 exists in the mind map, node 1 is a root node, if node 2 and node 3 are added for node 1, node 2 and node 3 are child nodes of node 1, node 1 is a parent node of node 2 and node 3, node 1 and node 2 are different hierarchical levels and have a hierarchical connection relationship therebetween, node 1 and node 3 are different hierarchical levels and have a hierarchical connection relationship therebetween, but node 2 and node 3 do not have a hierarchical connection relationship and are the same hierarchical level; if node 4 and node 5 are added to node 3, node 4 and node 5 are child nodes of node 3, node 3 is a parent node of node 4 and node 5, node 3 and node 4 are at different hierarchical levels, and there is a hierarchical connection relationship between them, node 3 and node 5 are at different hierarchical levels, and there is a hierarchical connection relationship between them, and node 4 and node 5 are offspring nodes of node 1, node 1 is a root node of node 4 and node 5, node 1 and node 4 are at different hierarchical levels, and there is a hierarchical connection relationship between them, node 1 and node 5 are at different hierarchical levels, and there is a hierarchical connection relationship between them, but node 2 and node 4 are at different hierarchical levels, but there is no hierarchical connection relationship between them.

Step S202, responding to node adjustment operation triggered by the mind map, obtaining an adjustment strategy of at least one first node, and selecting a reference node in the mind map;

in implementation, the embodiment of the application responds to the trigger node adjustment operation of the object on the mind map, and acquires the full data corresponding to the mind map triggered by the node adjustment operation.

The full data comprises node information of the nodes and a tree structure.

It should be noted that, since the full-scale data corresponds to the mind map, after the node adjustment operation is triggered on the mind map, the full-scale data corresponding to the mind map will change correspondingly according to the triggered node adjustment operation, and the acquired full-scale data includes data that changes correspondingly based on the node adjustment operation.

In this embodiment of the present application, the first node is a node in which data in the total data changes.

Optionally, in the embodiment of the present application, the adjustment policy of the first node at least includes: node screening, node folding, node addition, node element adjustment, node deletion, node allocation and the like.

Note that node folding is an operation triggered by a node having a child node, and when the adjustment policy is node folding, elements of the child node of the node are collapsed.

The node element adjustment in the embodiment of the application comprises the following steps: and adjusting the node marks and adjusting the node texts. The adjusting comprises the following steps: addition, deletion, modification, etc.

The node labels may be labels for classification, for example: p0, P1, etc.; node labels may also be labels for displaying unique meanings, such as: and (5) marking by hooking.

In the embodiment of the application, the node allocation is to allocate the nodes to the corresponding objects in the scene of multi-terminal collaborative writing of the mind map, display information of the corresponding objects in the peripheral range of the allocated nodes, and if the objects need to display only the nodes allocated to the objects based on the mind map after node allocation, when the objects trigger the operation of displaying the allocated nodes, the nodes with hierarchical connection relation between the root nodes and the allocated nodes and the corresponding descendant nodes of the allocated nodes are screened out through a node screening strategy according to the allocated objects.

The nodes with hierarchical connection relation between the root node and the distributed nodes comprise the root node and the distributed nodes.

It should be noted that, the display information of the object may include at least one of the following: the avatar information of the object, nickname information of the object, and the like, which is not limited in this application.

The embodiment of the application determines at least one first node based on the adjustment policy.

In the embodiment of the present application, the first node is a node in the mind map, which responds to a node adjustment operation triggered by the mind map, and the data is changed correspondingly due to an adjustment policy.

If the adjustment policy is node folding, the node to be folded is taken as the first node; if the adjustment strategy is newly added, the node triggered when the object triggers the node adjustment operation and the newly added node are used as the first node; if the adjustment strategy is node element adjustment, taking a node needing element adjustment as a first node; if the adjustment policy is node deletion, the node needing to be deleted is taken as a first node.

Referring to fig. 4, the adjustment policy is taken as an example of node element adjustment. If a P0 flag is added for node 8 as in fig. 4, the first node is node 8.

If the adjustment policy is node screening, the nodes which do not meet the screening condition need to be adjusted, and the root node and the nodes which need to be screened are taken as boundaries of corresponding branches according to the positions of the nodes which need to be screened, and the nodes which do not belong to the boundaries on each branch in the mind map are taken as first nodes.

For example, if a node with a P0 label needs to be screened out, the node that needs to be screened out is the node with the P0 label.

Referring to fig. 5, if a node with a P0 mark in the mind map needs to be screened, based on the position of the node with the P0 mark on each branch in the mind map, the root node and the node with the P0 mark are used as the boundaries of the corresponding branches, and the nodes 4, 5, 7, 9, 11, 12, 13 and 15 in the mind map are determined, and the nodes are the first nodes.

For example, if the adjustment policy is allocated to a node, and the node element information of the node needs to be adjusted, the node allocated by the triggered node is taken as the first node. And the front end needs to send the object identification of the object corresponding to the allocated node to the server, obtain the object display information of the object returned by the server, and determine the corresponding object display element according to the object display information, and then the node element information of the node comprises the object display element of the object.

After node allocation, if an object triggers node screening operation to screen out nodes allocated to the object, determining an adjustment strategy as node screening, and adjusting nodes not allocated to the object, wherein the positions of the nodes to be screened are determined according to the positions of the nodes to be screened, the root node and the nodes to be screened are taken as boundaries of corresponding branches, and the nodes which do not belong to the boundaries on each branch in the mind map are taken as first nodes.

Wherein the nodes to be screened are the nodes allocated to the object.

After a node is assigned to an object, the assigned node and its descendants are used as the nodes assigned to the object.

Illustratively, based on the fact that if node 3 is assigned to an object as shown in fig. 5, then node 3 and nodes 13, 14, 15 and 16 are considered as nodes assigned to the object, then the first node is: node 2, node 4-node 12.

The embodiment of the application selects a reference node in the mind map based on the determined adjustment strategy and the first node.

Wherein the hierarchy level of the reference node is not lower than any one of the first nodes;

it should be noted that, in the embodiment of the present application, if there is a first node, the reference node is the first node, or the reference node is a node that has a hierarchical connection relationship with the first node and has a hierarchical level not lower than the first node; if a plurality of first nodes exist, the reference node is a first node which has a connection relation with other first nodes and has a hierarchy not lower than the other first nodes in the plurality of first nodes, or the reference node is a node which has a hierarchy connection relation with all the first nodes and has a hierarchy level not lower than the first nodes.

For example, in the case where there is one first node, as shown in fig. 6A, if the first node is the node 8 shown in fig. 6A, the reference node may be any one of the following: node 1, node 2, node 8.

Illustratively, in the case where there are a plurality of first nodes, as shown in fig. 6B, if the first node is node 4, node 5, node 7, node 9, node 11, node 12, node 13, node 15 as shown in fig. 6B, the reference node is node 1.

For example, when there is a first node and the adjustment policy is not node deletion, the embodiment of the present application may determine a reference node by any one of the following ways:

mode 1, taking a first node as a reference node;

mode 2, taking a father node of a first node as a reference node;

mode 3, the root node of the first node is used as the reference node.

In an alternative embodiment, when the adjustment policy is node deletion, a parent node of the first node may be used as a reference node, or a root node of the first node may be used as a reference node.

It should be noted that, the above method for determining the reference node is a method provided in the embodiment of the present application, and if the condition in the method is not satisfied, it is determined that the reference node cannot be determined by using the method.

For example, if the first node does not have a parent node, the conditions in the above-described modes 2 and 3 are not satisfied, and the reference node cannot be determined using modes 2 and 3.

The method and the device are used for generating the node mapping relation corresponding to each node in the mind map based on the mind map of the triggered node adjustment operation according to the traversing copy of the full data corresponding to the mind map.

In the embodiment of the application, the node mapping relationship includes a hierarchical connection relationship between nodes.

Optionally, the embodiment of the present application may determine a reference node corresponding to the first node based on the node mapping relationship.

Step S203, traversing a reference node and corresponding offspring nodes to obtain at least one target node and corresponding adjustment results;

wherein, the target node is: after executing the adjustment strategy, the node presents the node with the affected state, and the adjustment result is: executing node information after adaptive adjustment by referring to an adjustment strategy;

in this embodiment of the present application, the node information includes node configuration information and node element information, where the node configuration information includes: the node coordinates, node element information includes: displaying the element;

the display elements comprise node text elements, node marking elements and object display elements.

As shown in fig. 7, a flowchart for obtaining a target node and a corresponding adjustment result according to an embodiment of the present application includes the following specific steps:

step S701, based on an adjustment strategy, obtaining a corresponding node adjustment mode;

the node adjustment mode comprises at least one of coordinate adjustment and element adjustment;

in the embodiment of the application, if the adjustment policy affects the node coordinates of the first node or affects the node coordinates of other nodes, determining that the node adjustment mode is coordinate adjustment; if the adjustment policy affects the display element of the first node, determining the node adjustment mode as element adjustment.

Optionally, if the adjustment strategy is: node screening, determining that the corresponding node adjustment mode is as follows: coordinate adjustment;

it should be noted that, in the embodiment of the present application, after node screening, only the screened nodes and the nodes having the hierarchical connection relationship between the node to be screened and the root node are displayed, so that the node coordinates of the screened nodes are affected, and the node adjustment mode is determined to be coordinate adjustment.

Optionally, if the adjustment strategy is: and adjusting the node elements, and determining the corresponding node adjustment mode to be: element adjustment;

It should be noted that, in the embodiment of the present application, the node element is adjusted to affect the element displayed by the node, and then the node adjustment mode is determined to be element adjustment.

The elements of the node presentation may include text, node marks, pictures, and the like.

Optionally, if the adjustment strategy is: and if the node is newly added, determining that the corresponding node adjustment mode is as follows: coordinate adjustment and element adjustment.

When the node adjustment operation corresponding to the node addition is triggered, the node addition affects the node coordinates of the newly added node and affects the display elements of the newly added node because the newly added node does not exist in the presented mind map, and then the node adjustment mode is determined to be coordinate adjustment and element adjustment.

Alternatively, the embodiment of the present application may determine the node adjustment manner as coordinate adjustment and element adjustment for each policy, which is not limited in this application.

Step S702, selecting at least one target node from a reference node and corresponding offspring nodes based on a node adjustment mode;

the descendant nodes of the reference node are nodes which have a hierarchical connection relation with the reference node and the hierarchical level is smaller than the hierarchical level of the reference node.

For example, as shown in fig. 8, based on fig. 6A, if the determined reference node is node 2, each descendant node of the determined reference node is: node 4, node 5, node 6, node 7, node 8, node 9, node 10, node 11, node 12.

Optionally, the embodiment of the present application selects at least one target node based on the node adjustment mode according to the information associated with the node adjustment mode in the obtained node information of the reference node and the corresponding offspring nodes.

The node information includes node configuration information and node element information, wherein the node configuration information includes basic information of the node, and the node element information includes display element information of the node.

In implementation, if the node adjustment mode comprises coordinate adjustment, acquiring node configuration information in the node information; and if the node adjustment mode comprises element adjustment, acquiring node element information in the node information.

The node configuration information includes: node id, node two-dimensional coordinates (e.g., x-coordinate and y-coordinate of node), size of node area (e.g., length, width, height of node area), node text content, node state, node collapsed state, hierarchical connection relationship of nodes, etc. The node element information comprises a display element, wherein the display element comprises at least one of the following components: node text elements, node markup elements, and so forth.

Optionally, when the obtained adjustment policy includes adjustment of text content in element adjustment, the obtained association information may be node element information including a node text element; when the acquired adjustment policy contains a marking element adjustment in the element adjustment, the acquired association information may be node element information containing a node marking element.

Exemplary, the node configuration information in this embodiment of the present application is shown in fig. 9, where id represents a node id, x and y represent two-dimensional coordinates of a node, width, height and depth represent dimensions of a node area, label represents a node text element, isHide represents a node state, collapsed represents a node folding state, and child array represents a hierarchical connection relationship of nodes.

The node state isHide may be a hidden state or a non-hidden state, and the node folding state collapsed may be a folding state or a non-folding state.

It should be noted that, the node text element label may be text content input by the object.

In the embodiment of the present application, the child array includes node configuration information of a child node corresponding to the node, which can represent a hierarchical connection relationship of the node.

Therefore, according to the node adjustment mode, the method and the device acquire the associated information in the node information, so that the number of acquired nodes can be reduced, the time for data processing is shortened, and the data processing efficiency is improved.

In practice, the embodiments of the present application select at least one target node according to at least one of the following manners:

in the first mode, when the node adjustment mode includes coordinate adjustment, at least one target node is selected from a reference node and corresponding descendant nodes.

Wherein, the target node is: and after the coordinates of at least one first node are adjusted, the coordinates of the nodes are adaptively adjusted.

Optionally, the embodiment of the present application selects at least one target node according to the following manner, and the specific process includes steps A1-A2:

a1, when a node adjustment mode comprises coordinate adjustment, acquiring node configuration information in associated node information;

in addition, in the embodiment of the present application, the node configuration information in the node information associated with the full-scale data is obtained according to the full-scale data corresponding to the mind map of the triggered node adjustment operation.

The associated node information is node information corresponding to a reference node and each corresponding descendant node.

Optionally, the embodiment of the present application determines node configuration information corresponding to a reference node and each corresponding descendant node based on the generated node mapping relationship.

It should be noted that, in the embodiment of the present application, the node mapping relationship may be expressed as a layoutMap.

The node mapping relation comprises a hierarchical connection relation among the nodes, and comprises mapping relations between each node and corresponding node configuration information.

In implementation, each descendant node of a reference node can be determined based on a hierarchical connection relationship between nodes in the node mapping relationship, and node configuration information corresponding to each descendant node is determined based on a mapping relationship between the nodes in the node mapping relationship and the node configuration information.

A2, selecting at least one target node from one reference node and each corresponding descendant node based on the acquired node configuration information of the reference node and each corresponding descendant node;

and B2, inputting the acquired node configuration information corresponding to the node in the non-hidden state into a coordinate transformation function, and carrying out coordinate transformation processing on the node coordinates in the non-hidden state.

Wherein, the target node is: aiming at the node adjustment mode, the node state is a non-hidden state, and the node information is adaptively adjusted.

And when the node adjustment mode comprises element adjustment, selecting at least one target node from one reference node and corresponding descendant nodes.

Wherein, the target node is: after element adjustment is performed on at least one first node, node elements are adaptively adjusted.

Optionally, the embodiment of the present application selects at least one target node according to the following manner, and the specific process includes steps C1 to C2:

note that, in the embodiment of the present application, node element information in node information associated with full data is obtained according to full data corresponding to a mind map of a triggered node adjustment operation.

Step C2, selecting at least one target node from one reference node and each corresponding descendant node based on the acquired node element information of the reference node and each corresponding descendant node;

When the node adjustment modes are coordinate adjustment and element adjustment, at least one target node selected in the first mode and at least one target node selected in the second mode are used as the final at least one target node.

Step S703, using the adjusted node information obtained for the at least one target node as an adjustment result of the at least one target node.

Optionally, the following cases are included in the embodiments of the present application:

when the node adjustment mode comprises element adjustment, taking the node element after the target node adjustment as an adjustment result of the target node;

when the node adjustment mode comprises coordinate adjustment and element adjustment, the following operations are respectively executed for each target node: when the node coordinates contained in the node information are adaptively adjusted, the node coordinates after the adjustment of the corresponding target nodes are used as adjustment results of the target nodes; when the display elements contained in the node information are adaptively adjusted, the node elements adjusted by the corresponding target nodes are used as adjustment results of the target nodes.

It should be noted that, the node coordinates and the display elements included in the node information corresponding to the target node may be adaptively adjusted, and both the adjusted node coordinates and the adjusted node elements are used as the adjustment results of the target node.

And step S204, re-rendering the mind map based on the adjustment result of at least one target node to obtain an updated mind map.

exemplary 1, referring to fig. 10, if the adjustment policy corresponding to the node 3 is node folding, and the mind map is re-rendered based on the adaptively adjusted presentation element of the target node, the child nodes (node 4 and node 5) of the node 3 are folded in the obtained updated mind map.

Referring to fig. 11, in example 2, if the adjustment policy is to screen the P0 marked node, the mind map is re-rendered based on the adaptively adjusted coordinate element of the target node, and only the node with the P0 mark and the node with the P0 mark having the hierarchical connection relationship with the root node, for example, the node 1, the node 2, the node 3, the node 6, the node 8, the node 10, the node 14 and the node 16 are shown in the obtained updated mind map.

It should be noted that, in the step S702, the rendering process corresponding to the mode may be referred to as a subtree rendering process by selecting the target node in the mode one; for the manner of selecting the target node through the manner two, the embodiment of the application may refer to a rendering process corresponding to the manner as a local rendering process.

In the rendering process, a node which is different from node element information in the mind map is used as a target node for re-rendering.

As shown in fig. 12, an overall flowchart of node screening according to an embodiment of the present application includes the following specific steps:

step S1201, responding to the node adjustment operation triggered by the mind map, obtaining a node screening policy, and obtaining full data corresponding to the mind map.

Note that, the full-scale data in the embodiment of the present application is data copied from the original data corresponding to the mind map. After the object triggers the node adjustment operation aiming at the mind map, the full data is correspondingly changed according to the node adjustment operation.

Optionally, in the embodiment of the present application, the main rendering logic is encapsulated as a function called caseLayout, where a parameter is a node id of a reference node, and by using the function, a total amount of tree node data is obtained, and node configuration information in node information is copied.

And determining parent-child relationships of the nodes according to the hierarchical connection relationship child arrays of the nodes in the node configuration information, thereby forming a tree structure.

In the process of traversing the copy, a node mapping relationship of the node is generated, and the node mapping relationship in the application may also be called a layoutMap.

Step S1202, traversing the reference node and corresponding descendant nodes by taking the root node in the mind map as the reference node, and screening out nodes with node states being non-hidden states.

Optionally, in the embodiment of the present application, based on acquiring the total data corresponding to the root node and each corresponding offspring node, and performing deep traversal on the acquired total data, if the node state isHide is true, the hidden state is determined, and if the node state isHide is false, the non-hidden state is determined.

The node configuration information of each node in the non-hidden state is obtained by removing the node in the hidden state in the obtained node configuration information.

It should be noted that, the obtained node configuration information of each non-hidden state node may be referred to as a showTree.

Step S1203, performing coordinate transformation operation on the nodes whose node states are not hidden, and selecting at least one target node.

The node configuration information containing the node in the non-hidden state is transmitted into a coordinate transformation function, and the node configuration information containing the updated node coordinates is obtained.

It should be noted that the coordinate transformation function may be a layoutMethod.

Optionally, according to the obtained node coordinates in the node configuration information containing the new coordinate information, the node coordinates in the original data corresponding to the mind map may be updated.

It should be noted that, the obtained target node is: nodes not represented in the mind map, and nodes represented in the mind map but the data in the corresponding node configuration information are not the same. The mind map is updated without node adjustment operations from the object.

The node configuration information of the corresponding node is obtained according to the node mapping relation layoutMap. The node configuration information comprises updated node coordinates, and the mind map is re-rendered based on the updated node coordinates.

In the implementation, in the process of determining the target node, the node configuration information of the node having the hierarchical connection relationship with the node can be obtained according to the hierarchical connection relationship child array of the node contained in the node configuration information, and the node configuration information is compared with the node corresponding to the mind map to determine the target node.

And step 1204, re-rendering the mind map based on the target node and the corresponding adjustment result to obtain an updated mind map.

By the method of the embodiment of the application, the following beneficial effects can be brought:

1. and (5) improving the rendering speed.

In the case of the number of nodes being 1w+, the time consumption of the node adding/deleting operation is about 10-20 ms, and the related technology is about 80ms, so that the rendering speed is improved by at least 4 times.

2. What is seen is the resulting presentation.

And after the object is screened according to the corresponding condition, directly presenting the result on the canvas, and obtaining the result without distinguishing or jumping of a special style.

3. And more nodes are carried, and the operation is smoother.

Currently, under a service scene, the thought guide graph can bear 20272 nodes, and operation is not stuck.

4. Under the multi-terminal cooperative scene, the mutual influence is avoided.

In the scene of multi-terminal collaborative writing of the mind map, each person can only watch the nodes allocated to the person, after the object screens the nodes allocated to the person, if the object changes the node state of the nodes, the source data is only required to be modified, and the mind map does not need to be re-rendered to other objects.

That is, when an object changes the node state, the mind map after the operation of the object may not be rendered to other objects, and when the other objects cancel the filtering, the changed content can be seen.
