FIG. 1 is a block diagram of a system for presenting a three-dimensional space model according to an embodiment of the present invention. Referring to FIG. 1 , a system for presenting a three-dimensional space model includes a client device 100 and an electronic device 200 . The client device 100 is, for example, an electronic device with computing capability and networking function, such as a smart phone, a tablet computer, a notebook computer or a personal computer used by a user. The electronic device 200 is, for example, a web server. The electronic device 200 and the client device 100 can be connected by a wired or wireless communication technology.

FIG. 2 is a block diagram of an electronic device for presenting a three-dimensional space model according to an embodiment of the present invention. The electronic device 200 includes a processor 210 , a communication element 220 and a storage device 230 . The processor 210 is coupled to the communication element 220 and the storage device 230 .

The processor 210 is, for example, a central processing unit (Central Processing Unit, CPU), a graphics processing unit (Graphics Processing Unit, GPU), or other programmable microprocessor (Microprocessor), digital signal processor (Digital Signal Processor, DSP), Programmable Controller, Application Specific Integrated Circuits (ASIC), Programmable Logic Device (PLD) or other similar devices.

The communication element 220 may be a chip or circuit using a local area network (Local Area Network, LAN) technology, a wireless local area network (Wireless LAN, WLAN) technology or a mobile communication technology. An example of a local area network is Ethernet. The wireless local area network is, for example, Wi-Fi. Mobile communication technologies are, for example, Global System for Mobile Communications (GSM), third-generation (3G), fourth-generation (4G), fifth-generation Mobile communication technology (fifth-Generation, 5G), etc.

The storage device 230 is, for example, any type of fixed or removable random access memory, ROM, flash memory, hard disk, or other similar devices or a combination of these devices. The storage device 230 is used for storing the database 231 and the three-dimensional space model 233 .

The database 231 stores a plurality of panoramic views. For example, the establishment of the ring view can be made by three-dimensional animation software, and can also be obtained by shooting with a camera. The virtual camera of the 3D animation software can simulate the camera in the real world, divide the 3D scene into photos of multiple angles, and make a panoramic view after this group of photos.

An embodiment is given below to describe the three-dimensional space model 233 . FIG. 3 is a schematic diagram of a three-dimensional space model according to an embodiment of the present invention. FIG. 4 is a schematic diagram of a three-dimensional space model including a plurality of positioning points according to an embodiment of the present invention.

The three-dimensional space model 233 is, for example, a three-dimensional space model 233 corresponding to a space generated by a three-dimensional model designer according to a customer's requirement using software such as a three-dimensional modeling tool, as shown in FIG. 3 . After completing the three-dimensional space model 233 , the three-dimensional model designer sets a plurality of positioning points P1 to P29 as shown in FIG. 4 on the three-dimensional space model 233 according to customer requirements, and sets them according to each of the positioning points P1 to P29 respectively. A corresponding one of the surrounding views is stored in the database 231 . In addition, at least one interactive position can be reserved in advance in the three-dimensional space model 233 according to requirements, so that the user can dynamically place other interactive elements. In the embodiment shown in FIG. 4 , 19 interactive positions E1 to E19 are preset in the three-dimensional space model 233 . Of course, this is only an example, and the number of anchor points and the number of reserved interactive positions are not limited.

In addition, the storage device 230 also stores a plurality of code fragments, and the above code fragments are executed by the processor 210 after being installed, thereby executing the following method of presenting the three-dimensional space model 233 .

FIG. 5 is a flowchart of a method for presenting a three-dimensional space model according to an embodiment of the present invention. Referring to FIG. 5, in step S505, the three-dimensional space model 233 is executed. For example, it is described that the client device 100 wants to connect to the electronic device 200 to open a three-dimensional web page. After receiving the connection notification, the electronic device 200 will execute the three-dimensional space model 233 .

After executing the three-dimensional space model 233 and before detecting the cursor operation command acting on the three-dimensional space model 233, the processor 210 can first use the preset surround view corresponding to the preset position as a material to insert the three-dimensional space model 233, The three-dimensional space model 233 that has been placed in the preset surround view is displayed on the display screen. Here, the preset position is one of the positioning points, and the preset panoramic image is one of the surrounding images. For example, the anchor point P3 is set as a preset anchor point.

Next, in step S510, when a cursor operation command acting on the three-dimensional space model 233 is detected, a specified positioning point with the smallest distance from the operation position corresponding to the cursor operation command is obtained from the plurality of positioning points.

In one embodiment, the user of the client device 100 can use an operating device such as a mouse or a touch panel to control the cursor on the display screen, and the stereoscopic image displayed on the display screen through the operating device such as the mouse or the touch panel can be controlled. When one part of the space model 233 is clicked, dragged or swiped, the client device 100 transmits the corresponding cursor operation instruction to the electronic device 200 . The processor 210 of the electronic device 200 receives the cursor operation command from the client device 100 through the communication element 220, and when detecting the cursor operation command acting on the three-dimensional space model 233, it will further calculate the operation position and the three-dimensional volume corresponding to the cursor operation command. The distance between each positioning point set by the space model 233, and the positioning point corresponding to the minimum distance is taken as the designated positioning point corresponding to the operation position. For example, if the cursor operation instruction corresponds to the click action, the click position is the operation position. If the cursor operation command corresponds to the drag action, the position when the drag action is released is taken as the operation position.

Afterwards, in step S515 , a designated lookaround image corresponding to the designated positioning point is retrieved from the multiple lookaround images included in the database 231 .

Next, in step S520 , the extracted designated surround view is inserted into the three-dimensional space model 233 as a material and displayed on the display screen. In one embodiment, after the processor 210 inserts the specified surround view image into the stereoscopic space model 233 as a material, the processor 210 further moves the virtual camera corresponding to the stereoscopic space model 233 to the specified positioning point. Afterwards, the three-dimensional space model 233 that has been placed in the designated surround view is displayed on the display screen of the client device 100 through the communication element 220 .

Here, the processor 210 uses a rendering method to insert the specified surround view image into the solid space model 233 as a material. Generally speaking, 3D models are covered with textures, and the process of placing texture arrangements on the 3D model is called texture mapping. After texture mapping, 3D models can be made more detailed and look more realistic. In this embodiment, the surround image is placed into the three-dimensional space model 233 as a texture-mapped material. In addition to texture mapping, surface normals can be adjusted to achieve lighting effects, and some surfaces can also use bump mapping and other stereo rendering techniques.

In addition, during the rendering process, the processor 210 uses the virtual camera to locate the relationship with each object in the stereoscopic space model 233, thereby obtaining a plurality of rendering parameters. In the real world, the eye sees an object because light is reflected to the eye through the object. The location of the virtual camera is the location of the "eye". Rendering parameters such as a reflection index corresponding to each pixel in the virtual camera and the three-dimensional space model 233 can be calculated by means of ray tracing. Therefore, after obtaining the specified positioning point, the processor 210 will further move the virtual camera to the specified positioning point, thereby obtaining rendering parameters corresponding to the specified positioning point.

In addition, a movable range is provided in the three-dimensional space model 233, and a plurality of anchor points are included in the movable range. The movable range is used to define which areas of the three-dimensional space model 233 need to be clicked to switch the surround view and clicks in which areas will not switch the surround view. For example, in the electronic device 200, if the processor 210 detects that the cursor operation command is applied to a position outside the movable range in the three-dimensional space model 233, it does not need to switch the surround view, but changes the current position in the display screen. Adjustment action is performed on the displayed surround view. The adjustment action includes moving, rotating or zooming. Here, the cursor operation command is a single-click command, a double-click command, a drag command, a pinch command, or the like. Different adjustment actions can be further performed for different cursor operation instructions.

That is to say, if the operation position corresponding to the cursor operation command is not within the movable range, there is no need to switch the panoramic view, and adjustment actions such as moving, rotating or zooming are directly performed on the currently displayed panoramic view.

In addition, the storage device 230 may further set an interactive component database. The interactive component database includes the interactive component and the interactive position of the interactive component in the three-dimensional space model 233 . The interactive elements are, for example, multimedia files, interactive interfaces or buttons. The processor 210 sets the interactive elements in the three-dimensional space model 233 according to the interactive positions corresponding to the interactive elements. And, when the operation position matches one of the anchor points, the relative position information between the anchor point and the interactive position is calculated, so as to adjust the rendering parameters of the interactive element based on the relative position information.

Assuming that the interactive element is set at the interactive position E1, if the surround view corresponding to the positioning point P3 is currently displayed, the processor 210 will calculate the relative positional relationship between the interactive position E1 and the positioning point P3, and then adjust the position of the interactive element in its position. The rendering parameters such as the rendering angle and light and shadow rendering in the corresponding surround view can be used to adjust its visual related effects. If switching to the look-around view of the anchor point P5, the processor 210 will recalculate the relative positional relationship between the interactive position E1 and the anchor point P5, and then adjust the rendering parameters of the interactive element in its corresponding look-around image. Accordingly, the presentation mode of the interactive element can be dynamically adjusted with the movement of the cursor, thereby obtaining a visual effect closer to the real space.

The user can operate the interactive elements in the three-dimensional space model 233 through the client device 100 . For example, it is assumed that the interactive component is a playback interface, which has a plurality of operation buttons, and the user can control functions such as playing, pausing, fast-forwarding or returning of the video by clicking the operation buttons in the playback interface with the cursor. For another example, if the interactive element is a button, the user can click the interactive element with the cursor to trigger the function corresponding to the button, such as connecting to another webpage, or displaying another layer of window interface on the three-dimensional space model 233 .

To sum up, the new creation uses a three-dimensional space model with a plurality of panoramic views, and selects the corresponding panoramic view based on the operation position corresponding to the cursor operation instruction. In addition, a plurality of interactive positions are reserved in the three-dimensional space model to set the interactive elements, and the presentation mode of the interactive elements is adjusted according to the operation positions. In this way, it can not only provide detailed and realistic images, but also ensure smooth operation on low-end terminals.
