Example 1:
A three-dimensional model exhibition interaction method based on a multidimensional variable expression, as shown in FIG. 1, comprises the following steps:
Step 1, a data set queries a three-dimensional model storage address required by a current service scene from the rear end according to a data set query condition, wherein the data set query condition binds a context variable;
And 2, triggering the three-dimensional model display interaction component bound with the data set to reload the display when the storage address of the data set query changes.
The steps are further described as follows:

When the data query conditions change, triggering the data set to query the three-dimensional model storage address required by the current service scene from the back end again.
The specific steps of the step 1 are as follows:
1) In the invention, a three-dimensional model loading display technology based on a data set is firstly constructed, wherein the data set is responsible for inquiring a three-dimensional model storage address required by a current service scene from the rear end, the inquiring condition can depend on a context variable, when the context variable changes, the data set is triggered to inquire data again, wherein a three-dimensional model display interaction component is responsible for loading display of the three-dimensional model, the component binds with a three-dimensional model storage address column of the data set, and when the address data changes, the three-dimensional model reloading display is triggered.

Example 3
Step 1, a data set queries a three-dimensional model storage address required by a current service scene from the rear end according to a data set query condition, wherein the data set query condition binds a context variable, and the specific implementation mode is as follows:
Determining the type and characteristic attribute of the required three-dimensional model according to the service scene to form a data set query condition;
Binding the query condition of the data set with the context variable to ensure that the query condition can dynamically adapt to different service scene requirements;
Searching the matched three-dimensional model record in a back-end database according to the data set query condition to acquire model information meeting the condition;
and filtering and sequencing the retrieved three-dimensional model records, and preferentially selecting the model with the highest correlation with the current service scene.
And extracting storage address information in the three-dimensional model record, and checking the address format and the validity.
And correlating the acquired three-dimensional model storage address with corresponding model attribute information to form complete model acquisition result data.
And returning the model acquisition result data to the front end for use in rendering and displaying the three-dimensional model of the service scene.
And determining the required three-dimensional model type and characteristic attribute according to the service scene to form a data set query condition.
For example, in a smart city management scenario, a three-dimensional model of a city infrastructure such as a building, a road, a greening, etc. needs to be acquired, and the model needs to contain attribute information such as a name, a type, a size, a coordinate position, etc.
The system dynamically generates database query statements by binding these conditions with context variables (e.g., current city, region, time, etc.).
And the back-end database searches the matched three-dimensional model record according to the query statement, and adopts algorithms such as inverted index, boolean model and the like to rapidly acquire the model information meeting the conditions.
And then filtering and sequencing the search results, comprehensively considering the factors such as the relevance, the integrity, the updating time and the like of the models, calculating the comprehensive score of each model by using a weighted average algorithm, and preferentially selecting the model with the highest score.
And then extracting the storage address information in the model record, and checking the address format through the regular expression to ensure that the address accords with the URL specification.
And finally, associating the model address with the model attribute information, and generating JSoN-format result data to return to the front end.
The front end selects a proper three-dimensional rendering engine and a proper technical frame according to the service scene requirement, and loads and displays the acquired model data to realize the visualization and interactive operation of the three-dimensional scene.
Through the series of processes, a complete link from a service scene to a three-dimensional model is obtained and displayed, and the management and application efficiency of three-dimensional data are improved.
And 2, triggering the reloading and displaying of the three-dimensional model display interaction component bound with the data set when the storage address of the data set query changes, wherein the method comprises the following specific implementation steps of:
Acquiring a storage address of data set inquiry, judging whether the address is changed, and if so, triggering reloading of a three-dimensional model display interaction assembly associated with the data set;
acquiring a three-dimensional display controller of a three-dimensional model display interaction assembly, and binding attributes such as camera coordinates, visual angles and the like with context variables through a multidimensional variable expression;
Monitoring the change of the context variable, if the change is detected, triggering the change of the attributes such as the camera coordinate, the visual angle and the like, and transmitting the changed attribute value to the three-dimensional display controller;
and the three-dimensional display controller adjusts the display effect of the three-dimensional model according to the received change values of the attributes such as the camera coordinates and the visual angles, and the like, so that the refreshing of the three-dimensional model display is realized.
And training the historical display effect data of the three-dimensional model by adopting a support vector machine algorithm to obtain an optimal combination of camera coordinates and visual angle parameters for optimizing the display effect of the follow-up three-dimensional model.
And analyzing the interactive behavior data of the users through a clustering algorithm to obtain interactive preferences of different user groups, dynamically adjusting the display effect of the three-dimensional model according to the interactive preferences, and providing personalized three-dimensional model display service.
An evaluation model of the three-dimensional model display effect is built, the three-dimensional model display effect is evaluated by adopting a decision tree algorithm, and the attributes such as camera coordinates, visual angles and the like are dynamically optimized according to the evaluation result, so that the quality and the user experience of the three-dimensional model display are continuously improved.
First, the system will obtain the storage address of the dataset query, e.g., by accessing the metadata table in the database, and obtain the storage path of the dataset as "/data/dataset/model_data".
The system then compares the currently acquired memory address with the last stored address and if a change in address is found, triggers a reload of the three-dimensional model presentation interaction component associated with the dataset.
Next, the system obtains a three-dimensional presentation controller of the three-dimensional model presentation interactive component, and binds attributes such as camera coordinates (x, y, z) and viewing angles (yaw, pitch, roll) with context variables (e.g., user ID, timestamp, etc.) through a multi-dimensional variable expression.
The system monitors the change of the context variable in real time, for example, when the user A accesses the system at 2023-05-20:30:00, the generated context variable is { userID: "A", timestamp: "2023-05-20:30:00" }, once the change of the context variable is monitored, the change of the attributes such as the coordinates and the visual angle of the camera is triggered, and the changed attribute values such as (15,28,12) and (45 degrees, 60 degrees and 30 degrees) are transmitted to the three-dimensional display controller.
And the three-dimensional display controller adjusts vertex coordinates and rendering parameters of the three-dimensional model through algorithms such as matrix transformation and the like according to the received change values of the attributes such as the camera coordinates and the visual angles, so that refreshing of the three-dimensional model display is realized.
Meanwhile, the system also adopts a Support Vector Machine (SVM) algorithm to train the historical display effect data of the three-dimensional model.
By selecting a Gaussian kernel function, setting a penalty coefficient C=0, training 10000 sample data, and obtaining the optimal combination of camera coordinates (13,17,6) and view angle parameters (60 degrees, 45 degrees and 25 degrees) for optimizing the display effect of the follow-up three-dimensional model.
In addition, the system analyzes the interactive behavior data (such as clicking times, access time length and the like) of 5000 users through a K-means clustering algorithm, divides the users into 3 groups, respectively acquires the interactive preference (such as group A preference overlooking angle, group B preference horizontal viewing angle and the like) of each group, dynamically adjusts the display effect of the three-dimensional model according to the interactive preference, and provides personalized three-dimensional model display service.
Finally, the system also builds an evaluation model of the three-dimensional model display effect, adopts a CART decision tree algorithm, and generates a decision tree model by analyzing the characteristics (such as frame rate, loading time and the like) of 1000 three-dimensional model display effect samples and user scores.
And evaluating the new three-dimensional model display effect according to the decision tree model to obtain a score of 2 minutes (full score of 5 minutes), and dynamically optimizing the attributes such as camera coordinates and visual angles according to the evaluation result, for example, adjusting the camera coordinates to be (18,12,11), and adjusting the visual angles to be (55 degrees, 50 degrees and 20 degrees), so that the quality and the user experience of the three-dimensional model display are continuously improved.
