In some embodiments, each user's operation request to interact with the virtual reality exhibition page is obtained through the virtual reality exhibition page, requiring an application to handle the various requests and data storage operations.
Further, the step of creating this application is as follows:
firstly, create a project, this embodiment takes a node. Js project as an example, secondly, install packages for the project, for example, 'Express' (Web framework), 'monglose' (ODM (object data model) library of monglodb), 'body-partner' (middleware of parsing request body), and again connect databases, for example, monglodb databases, then create Express application and corresponding API interface under the project, process requests through API interface and interact with databases to call data, for example, because of API interface, allow cross-domain request, and at the same time can obtain all display information through 'API/exhibits', or obtain specific display information through 'API/exhibits/: id'.
After running the application, either 'http:// localhost 3000/users' can be accessed to get all users, or a POST request can be used to send JSON data to the URL to add a new user.
Further, functions such as error handling, verification, authorization, logging, etc. may also be added to the application.
And S4, responding to an operation request sent by a user, adjusting a display mode of displaying the image or the display information in the virtual three-dimensional space, and sending the image or the display information after the display mode adjustment to the user.

For example, when the user a enlarges the picture C in the virtual three-dimensional space, the enlarged picture C will be displayed to the user a, and when the user B rotates the picture D in the virtual three-dimensional space, the rotated picture D will be displayed to the user B.
When a large amount of pictures and exhibition information exist in the virtual three-dimensional space of the virtual reality exhibition hall page, the loading speed of the page is reduced, and in order to accelerate the loading speed of the page, image data needs to be processed.
Optionally, in some embodiments, using a Content Delivery Network (CDN), the image is obtained from a server that is the fastest for the user to obtain, thereby speeding up the loading of the virtual reality showroom pages.
Optionally, in some embodiments, the image is saved to a cache of the browser, such that the image is retrieved from the cache of the browser when the user browses the image again in the virtual reality exhibition page.
Optionally, in some embodiments, the online virtual reality image display method further includes: converting the image data into a plurality of pictures (one for each preset conversion format) based on the plurality of preset conversion formats; each picture is compressed. Based on the above, in response to an operation request sent by a user, adjusting a display manner of displaying an image in a virtual three-dimensional space, including: responding to an operation request sent by a user, and acquiring a compressed target picture corresponding to the operation request; decompressing the compressed target picture; determining a display mode of the decompressed target image according to equipment used by a user; and according to the operation request, adjusting the display mode of the decompressed target image in the virtual three-dimensional space.
In some embodiments, the preset conversion format is selected according to the requirement, and different conversion formats have different compression algorithms and application scenes. For example, PNG format or SVG format is the best choice for images with a small number of colors. For photographs, the JPEG format may be a better choice. New formats, such as WebP format, provide better compression but may not be supported by all browsers, requiring selection for compatibility.
It will be appreciated that the step of determining the manner of displaying the decompressed target image according to the device used by the user and displaying the decompressed target image to the user refers to adapting and providing the most suitable image version according to the device characteristics (such as the screen size, resolution, viewport size or other factors of the device), and then displaying the decompressed target image to the user according to the most suitable image version. The aim is to ensure that the user can obtain an optimal visual experience under various device and network conditions, while avoiding unnecessary data transmission.
Further, according to the equipment used by the user, determining the display mode of the decompressed target image, and displaying the decompressed target image to the user, the specific implementation method of the steps comprises the following steps:

Optionally, setting < picture > ' and ' source ' in the virtual reality exhibition page, and using the ' picture > ' element and the ' source ' sub-element therein, different image sources can be provided for different devices and screen characteristics.
Optionally, a CSS background picture is set in the virtual reality exhibition page, and different background images can be provided for different view ports and device characteristics using CSS media queries.
The method can ensure that each device obtains the optimized image, thereby realizing faster loading speed and better user experience.
Alternatively, in some embodiments, the delayed loading is set by means of delayed loading, i.e. loading a page with an image and the acquisition of the image only when the user scrolls to the image, in particular by means of the code' loading= "lazy" attribute at the browser.
Further, in some embodiments, the online virtual reality image presentation method further comprises: the following steps are performed after the operation request of each user for interaction with the virtual reality exhibition page is acquired:
(110) And acquiring behavior data of interaction between the user and the virtual reality exhibition hall page.
In some embodiments, the behavior data that may be collected includes page scroll speed and direction, mouse movement trajectory and speed, user dwell time on the page, historical browsing data (e.g., which portions or links the user frequently accesses).
(120) And judging the next operation behavior of the user through a preset prediction model based on the behavior data.
It should be noted that after the behavior data is acquired, significant features need to be extracted from the behavior data, for example, an average moving speed, a moving direction, a recent acceleration, etc. are extracted from the mouse moving data, and the behavior data is labeled, that is, a label is assigned to each data point based on historical data or expert knowledge, to indicate an expected behavior of the user, for example, whether the user clicks a button or a link.
Before the behavior data is input into the prediction model for operation, the method further comprises the following preparation steps:
a suitable supervised learning model is selected based on the nature of the problem, alternatively for a bi-classified problem (e.g., whether the user would click on a link), a logistic regression model, a support vector machine model, or a random forest model may be selected, but for a multi-classified or regression problem, other models may be required.
Dividing the marked behavior data into training set data and verification set data, training the selected supervised learning model by using the training set data, and evaluating the trained supervised learning model by using the verification set data, wherein common evaluation indexes comprise accuracy, recall rate, F1 score and an AUC-ROC curve.
When the evaluation index is reached, taking the verified supervised learning model as a preset prediction model, and judging the next operation behavior of the user through the preset prediction model.
Further, since the user's behavior may change over time, new data is collected, re-labeled, trained, and updated periodically.
It will be appreciated that analysis of user behavior data with supervised learning requires extensive understanding of the data, selection of appropriate models and features, and continuous optimization and updating. This may help us better understand the intent and needs of the user, providing a better user experience.
(130) Based on the next operational behavior, targeted content and non-targeted content are determined.
In this embodiment, different decisions are determined based on different next operational behaviors. If the next action of the user is to view a certain part or click a certain link, the resource (such as a picture, video or text information) related to the certain part or click a certain link can be loaded in advance, that is, the target content (such as the picture, video or text information) needing to be loaded in advance can be determined, and the other content is non-target content.
(140) And acquiring target content, judging whether an instruction of browsing non-target content by a user is detected, if so, acquiring the non-target content, and if not, stopping acquiring the non-target content, wherein the target content comprises a compressed target picture.
If the target content is the target content, the target content is loaded in advance, so that a user can conveniently and quickly acquire the target content. And if the user does not view the non-target content to be viewed by the next action of the user, loading by adopting a delayed loading strategy, or even if some non-target content with extremely low probability of being viewed by the next action of the user is not loaded, for example, when a mouse of the user scrolls to a picture of a certain non-target content, an instruction of the user for browsing the non-target content is detected, a page where the picture of the non-target content is located is loaded, and the picture of the non-target content is acquired. If the mouse of the user scrolls to the picture of a certain non-target content, the picture of the non-target content is not loaded and not acquired.
By predicting the possible next operation of the user, the system can more intelligently determine which resources should be loaded immediately and which should be delayed, so as to avoid slowing down the loading speed of the page due to loading the whole content (picture, video or text information) of the page at one time.
Optionally, in some embodiments, the online virtual reality image presentation method further includes: after converting image data into a plurality of pictures based on a plurality of preset conversion formats, processing each picture obtained by conversion to obtain a plurality of first views of each picture at a plurality of preset angles; obtaining a plurality of second views of the virtual three-dimensional space at a plurality of preset angles; and fusing the corresponding first view and second view to obtain display pictures when a user browses the image data at any preset angle, and compressing and storing each display picture in a database.
The above preset angles may be determined according to a common key angle when one or more users browse the image data, for example, the preset angles may be key angles of 30 degrees on the left side, 45 degrees on the left side, 75 degrees on the left side, 30 degrees on the right side, 45 degrees on the right side, 75 degrees on the right side, and the like. Taking 7 preset angles as an example, each picture has 7 first views corresponding to the 7 preset angles, the virtual three-dimensional space also has 7 second views at the 7 preset angles, and the corresponding first views and the second views are fused (for example, the first view at 30 degrees on the left side and the second view at 30 degrees on the left side are fused), so that a display picture when a user browses image data at any preset angle is obtained.
On the basis, the online virtual reality image display method further comprises the following steps: after determining the target content and the non-target content based on the next operation behavior, predicting a browsing order of the user for the image data (for example, browsing the image data in a number increasing manner) based on the behavior data; according to the browsing sequence, acquiring all compressed display pictures corresponding to N pieces of image data to be browsed after target content from a database, decompressing and caching the display pictures in a user local area, wherein N is a positive integer between 2 and 10, and can be specifically determined according to the time of browsing single image data, and the longer the time is, the smaller the numerical value of N is; when a user browses one of N image data to be browsed, and the real-time network speed of the user is smaller than a preset threshold value, responding to an operation request sent by the user, locally calling the display picture of the image data corresponding to the preset angle from the user to be displayed to the user, at the moment, displaying of the picture of the key angle can be realized without occupying the network speed of the user, and the user is ensured to obtain basic interactive experience. If the operation request and the preset angle cannot be completely matched, selecting a display picture with the closest preset angle for display, for example, if the operation request corresponds to 80-degree image data from the left side, locally retrieving a display picture with 75-degree left side from the user for display.

Texture of the three-dimensional model is reduced to reduce memory usage and loading time of the GPU.
Texture atlas is used to merge multiple textures in a three-dimensional model into one, thereby reducing draw calls at rendering.
Several different levels of detail are created for the model and the appropriate level is selected for rendering based on the camera-to-model distance. Models that are farther away use lower levels of detail.
The geometry inside the model or occluded by other objects is deleted.
Rendering can be accelerated using a simple shader and a small amount of material.

Each particle has a velocity that determines its direction and distance of movement in the solution space. Each particle remembers the best of its visited locations; secondly, evaluating the current position of each particle by using an objective function, which is beneficial to determining the quality of the solution; thirdly, updating the speed and the position of the particles; and step four, judging whether the algorithm meets certain convergence conditions, if the maximum iteration times are reached, the improvement of the objective function is smaller than a certain threshold value or other stopping criteria, if the convergence conditions are not met, returning to step 2, otherwise, outputting the best position (solution) found in the group and the corresponding objective function value. Wherein for each particle in the population, the velocity and position of the particle is updated according to the following formula:
Wherein,for the speed of particle i at time t+1, < >>For the position of particle i at time t+1, w is the inertial weight, c 1 c 2 Are learning factors, r 1 r 2 Is [0,1]Random numbers within range, p best G for the best position visited by particle i best The best location visited for the entire population.
(230) And outputting the first optimized three-dimensional model when the model parameters of the adjusted three-dimensional model reach the target values and are within the range of the constraint conditions.

It will be appreciated that depending on the result of the analysis, a new algorithm is selected, which may be a preset algorithm that adjusts the algorithm parameters or another preset algorithm is selected, and then the new algorithm is re-executed. This process may require multiple iterations until a satisfactory optimized three-dimensional model is obtained.
