『Use example 2』 Display of 720-degree panoramic view page

For the presentation of the 720 degree view, please refer to the ninth A and B pictures and the tenth picture. When the page A is displayed on the 720 degree view, the page A refers to a three-dimensional view page L1 including a three-dimensional coordinate system. The 720-degree panoramic view webpage can be rotated 360 degrees in one of the horizontal coordinate and the vertical coordinate direction of the three-dimensional coordinate system, and one of the transient display coordinates corresponding to one of the display states is located in the three-dimensional display coordinate system. The temporary display coordinates are stored in the data management storage module 13 in the coordinate system. The method for controlling the horizontal coordinate of the three-dimensional scene to change the horizontal coordinate and the vertical coordinate is not limited, and the method may be: comparing a cursor to an orientation relationship between a track coordinate of the temporary display display and the temporary display coordinate, so that the The webpage L1 of the three-dimensional scene view moves or switches to display the information content of the other temporary display coordinates; or, it may be a comparison of the orientation result of the mobile device of the user (for example, the azimuth sensing result of the built-in gyroscope of the smart phone) and The transient displays the orientation of the coordinates. Taking the track coordinates as an example, assume that the transient display coordinates are the origin (0, 0, 0) of the three-dimensional coordinate system. When the track coordinates are (0, 1, 0), the user wants to be horizontally clockwise. The direction changes the display content of the transient display screen. The three-dimensional scene view webpage L1 may include a label module L12 for connecting to a first-order webpage (P1) or for connecting to any of the n-th order webpages {P1, P2... or Pn} or an entrance. The webpage, through the tag modules L12, L13, makes the switching relationship and path between the webpages very diverse, and the connection path relationship can be as shown in FIG.

The three-dimensional scene view webpage L1 may include a display object L11, which is actively downloaded by the database 20 in a specific context and performs an interactive information display in the transient display screen, so that the user can browse the three-dimensional scene view. The web page L1 actively accepts the message and continuously obtains the latest information automatically from the database. News. The display of the display object L11 is not limited, for example, it may be a large animated billboard, a T-bar display card, a work display cabinet, an information bulletin area, etc., which is located on the n-th webpage of the portal webpage, when the specific situation When satisfied, the display object can display different and interactive interactive information according to its type and presentation mode, for example, playing animations, latest news, latest event information, and emergency announcement messages on the large animated billboard; The cards display the latest events and advertisements; the statues and paintings in the exhibition are displayed in the art display cabinet; and the news events are displayed in the information bulletin area. The foregoing specific situation satisfaction condition may be plural according to the type and presentation form of the display object. For example, the specific situation satisfaction may be: the transient display coordinate is located in a set interval, and the location meets the set condition (close to a certain building, The road junction or the scenic spot), the time meets the set conditions (a certain event period, when the whole news is played), and the like.

The following is a few examples to illustrate the actual relationship between the three-dimensional scene web page L1, the display object L11, and the label module L12, L13:

Please refer to the ninth B and the tenth drawings, which show a webpage L1 of the three-dimensional scenery presented by the transient display screen displayed by the user's mobile device, and the webpage L1 of the three-dimensional scenery is a building. More than one display object L11, the label module L12, L13 is marked on the webpage of the theme of the building, and one of the display objects L11 is a large LED kanban, and the display object L11 outputs the interactive information when the specific situation is met. It is shown that the specific situation may be that the display object L11 is compared and updated to the latest state by the database when the transient display coordinates fall within a set range. Taking the large LED billboard of the department store as an example, when the user browses the webpage L1 of the three-dimensional scene and displays the transient display screen completely (that is, the specific situation is satisfied) The display object L11, the display object L11 starts to be downloaded from the database to the latest advertisement, the anniversary sale event image, etc., when the user moves the mouse to convert the transient display screen to the invisible display object L11 At the time (ie, the specific situation is not satisfied), the webpage L1 of the three-dimensional scene actively stops playing the latest advertisements and the like, so that the user can not only actively receive and update each time when browsing a single three-dimensional scene webpage L1. The display object L11 corresponds to the latest information content, and the user can receive the information update without entering other hyperlinks. Moreover, due to the 720 degree view webpage provided by the embodiment, the single webpage L1 of the three-dimensional scenery can be included. The amount of information breaks through the information content that a traditional single page can hold. For another example, the display item L11 is a vending product, and when the vending product satisfies the specific situation, the database updates the latest selling price and product introduction information.

The portal page or the specific area of the n-th page can automatically generate a plurality of the label modules L12, L13. The portal page or the n-th page can be a first-order three-dimensional webpage L2 or a display object, and the user selects the label. After the module L13 enters the second-order three-dimensional webpage L2, the second-order three-dimensional webpage L2 is an indoor space of the building of the webpage L1 of the three-dimensional panoramic view, and the second-order three-dimensional webpage L2 is a 720-degree panoramic webpage, The display unit L21 and the label module L13 are included, and the second-order web page L2 can be returned to the web page L1 of the three-dimensional scene through the label module L13. When the user clicks the label module L13, it is quickly converted between the portal webpage or the n-th webpage, wherein the display object can also be compared in the specific state after the comparison module is matched. After that, the content corresponding to the database 20 is updated synchronously.

As can be seen from the foregoing description, the present embodiment has the following features:

1. Different search contents are layered and stored in an object array in a special format, so that the web page can display different search contents quickly and efficiently, avoiding technical problems of repeated downloading, time consuming, and waste of network bandwidth.

2. Many of the information that has been found can be solved without re-finding, and the problem that the existing technology must consume a lot of resources and repeat the query.

3. The search code is used to judge the layer currently displayed on the webpage, so as to quickly clear and switch the displayed content, and reduce the processing time and download time of the mobile device.

4. The three-dimensional webpage of the embodiment not only gives a page displayable range of expansion to 720 degrees, but also greatly increases the amount of information that can be accommodated in each page; the three-dimensional webpage is a multi-functional interactive display, and the webpages are mutually integrated and intercommunicated. Therefore, it is different from the choice of the previous page and/or the next page when the web page operation is performed.

5. Through the database comparison (for example, keyword comparison) to achieve the purpose of "personnel and place" information in tandem.
