Detailed Description
Example 1
The instant discussion system based on the three-dimensional model disclosed by the embodiment comprises a three-dimensional model server, a client, a model operation conflict resolution module, a time sequence control module and an instant communication module.
The three-dimensional model server is used as a control center of the system and can store the lightweight model data.
The client can be a computer, a mobile terminal and the like, the number of the client can be set to be multiple, one user corresponds to one client and is used for initializing the instant discussion scene, displaying three-dimensional model data through a graphic engine, providing online operation of the three-dimensional model, sending real-time voice, text and picture information to the three-dimensional model server and receiving the real-time voice, text and picture information sent by the three-dimensional model server.
The model operation conflict resolution module is used for ensuring that only one user operates the model in unit time through the operation locking mechanism when the client sends out the three-dimensional model operation request.
Wherein, the operation locking mechanism is as follows: when all users need to perform three-dimensional model operation through the client, an operation lock request is carried out, namely, a three-dimensional model operation request is sent out, if no user performs three-dimensional model operation at present, the user which sends out the three-dimensional model operation request firstly obtains the right of operating the three-dimensional model, and other users cannot perform three-dimensional model operation and only can perform operation information synchronization. If a plurality of users send three-dimensional model operation requests at the same time, priority sorting is carried out according to the user weight, and users with high priority first obtain an operation lock, namely the users with high priority first obtain the right of operating the three-dimensional model. And when the user finishes operating the three-dimensional model, automatically releasing the operation lock. The conflict caused by the fact that multiple users operate the three-dimensional model at the same time can be avoided through the operation locking mechanism, and it is guaranteed that only one user operates the model in the same time period, and other users can only synchronously update and check the operation.
The time sequence control module is used for carrying out time sequence control on the operation of the plurality of clients according to a first-come-first-serve principle, and ensuring that each operation instruction is restored and displayed on other clients in sequence.
The instant communication module is used for keeping long connection and data transmission between each client and the three-dimensional model server.
The instant discussion method based on the three-dimensional model, which is realized by adopting the instant discussion system based on the three-dimensional model, comprises the following steps:
step 1: the operations involved in the instant discussion based on the three-dimensional model are encoded, including: text sending, picture sending, model switching, view angle changing, model zooming, translation, component selection, model roaming and the like.
The discussion initiator selects the area scene of the three-dimensional model through the client according to the content to be discussed, initializes the selected area scene of the three-dimensional model through the client, then displays the area scene of the three-dimensional model on the client, and simultaneously selects the initial view angle of the area scene of the three-dimensional model.
The area scene of the three-dimensional model refers to a plurality of projects, a single project or a single project mark segment, and relates to the area model, including three-dimensional models of buildings and gardens and geographic environment information. The user terminal initializes the selected three-dimensional model area scene, namely, a graphic engine of the user terminal loads lightweight model data of the selected area, the user terminal receives component and attribute information of the three-dimensional model from the three-dimensional model server, the component and the attribute information are loaded and displayed through the graphic engine, and an initial display view angle is set.
Step 2: a discussion sponsor creates a discussion group in the three-dimensional model area scene through a client, selects user members needing to participate in discussion, and uploads discussion group information to a three-dimensional model server; the three-dimensional model server pushes the discussion group information to the client of the selected discussion group member, the information can inform the members through short messages and mails, and the partial user members are invited to enter the discussion group. The discussion group information comprises group participants, discussion subjects, three-dimensional models and model views; the users participating in the discussion can only select from accounts already registered in the system.
And 3, step 3: after receiving the discussion group information pushed by the three-dimensional model server, the client of the selected user member can join the discussion group through the notification link. Meanwhile, the selected member receives the three-dimensional map, the components of the three-dimensional model and the attribute information through the client side of the selected member to initialize, loads and displays the regional scene of the three-dimensional model through a graphic engine, and switches to the initial view angle selected by the discussion initiator.
And 4, step 4: after all members participating in the discussion enter the discussion group, the group members start to discuss the content. The discussion process comprises instant messaging and three-dimensional model operation.
Specifically, the instant messaging includes the following steps:
step 410: and the members in the discussion group send real-time voice, text or picture information to the three-dimensional model server through the client sides of the members.
Step 411: the three-dimensional model server carries out time sequence processing on the received real-time voice, character or picture information, adds a unique time sequence number for each piece of information, namely uniquely numbers the voice, character or picture information according to the time sequence.
Step 412: the three-dimensional model server sends the real-time voice, text or picture information added with the time sequence number to the client sides of all members in the discussion group, and displays the sent information on the client sides according to the sequence number.
For example: the user inputs real-time voice, characters or pictures at the client A and sends information to the three-dimensional model server, the three-dimensional model server numbers the information according to time sequence and pushes the real-time voice, characters or picture information to the clients of other members B and C in the discussion group, and the clients B and C display the real-time voice, characters or picture information according to the time sequence number of the information. The user inputs real-time voice, characters or pictures at the client B and sends information to the three-dimensional model server, the three-dimensional model server numbers the information according to time sequence and pushes the real-time voice, characters or picture information to the clients of other members A and C in the discussion group, and the clients A and C display the real-time voice, characters or picture information according to the time sequence number of the information.
When the client sends the real-time voice, character or picture information, the user directly sends the real-time voice, character or picture information, and the three-dimensional model server directly sends the information to other clients as common information when processing the part of information. The method also comprises the steps that after a user selects a model viewpoint, specifically a single component or a plurality of components, real-time voice, character and picture information related to the selected model component is sent, and when the information is sent, the client automatically associates the model information (components and viewpoints) with the real-time voice, character and picture information. When processing the part of information, the three-dimensional model server synchronously sends the model information (components and viewpoints) and the real-time voice, character and picture information to other clients. The client automatically adjusts the model scene, the model viewpoint and the corresponding component when displaying the real-time voice, character and picture information associated with the model. In the process of discussion and meeting, the three-dimensional model server judges the state through the communication module, and if the user is online, the information is directly pushed to the client; and if the user is not online, performing centralized data pushing after the user client is online.
In addition, the three-dimensional model operation performed by the user includes the following steps:
step 420: the members in the discussion group send a three-dimensional model operation request to the three-dimensional model server, wherein the three-dimensional model operation request is automatically triggered when the client operates on the three-dimensional model, for example, the client automatically triggers when the client performs operations such as model switching, view angle change, model zooming, translation and component selection.
Step 421: the three-dimensional model server judges which member can obtain the operation right according to the three-dimensional model operation request sent by the member; the specific determination method is as follows:
the three-dimensional model server firstly judges whether a member is currently performing three-dimensional model operation; and if so, rejecting all current three-dimensional model operation requests, wherein all members sending the three-dimensional model operation requests cannot operate the three-dimensional model. If not, the three-dimensional model server distributes the operation right to the first member sending the three-dimensional model operation request according to the time of all the three-dimensional model operation requests, and other members cannot operate the three-dimensional model at the moment; and if the plurality of members send out the three-dimensional model operation requests at the same time, carrying out priority ordering according to the user weight, and distributing the operation right to the member with higher priority. Therefore, the conflict caused by the fact that multiple users operate the three-dimensional model at the same time can be avoided, and only one user operates the model in the same time period.
Step 422: and the member obtaining the operation right operates the three-dimensional model through the client and sends the three-dimensional model operation information to the three-dimensional model server. Wherein the operation on the three-dimensional model comprises: a model switching operation, a perspective changing operation, a model scaling operation, a model panning operation, a selection member operation, and/or a model roaming operation.
Step 423: and the three-dimensional model server uniquely numbers the three-dimensional model operation information according to time sequence, sends the three-dimensional model operation information to clients of other members in the discussion group according to the time sequence number, and displays the three-dimensional model operation information of the clients receiving the information according to the time sequence.
Step 423: when the operation of one member on the three-dimensional model is completed, the system automatically releases the operation right, and then returns to step 420 to redistribute the operation right. Of course, the user may also send real-time voice, text, and picture information associated with the model while performing the three-dimensional model operation.
And 5: and closing the discussion group after the instant discussion is finished, and stopping the model operation and the information synchronization among the user clients.
In the embodiment, the pictures, the characters and the three-dimensional model operation information of each client are synchronized in real time, and the same model is sequentially restored, so that the members of the same group can share the operation information of the three-dimensional model while communicating at the moment, and the consistency of the three-dimensional space information seen by the members in the group is ensured.
