[0047] With the continuous deepening of three-dimensional technology, more and more businesses are displaying products in virtual electronic model rooms through electronic screens, such as 360 panoramic technology and VR-based three-dimensional scene real-life roaming. The former is actually pseudo-3D technology, which can only be viewed in a circular manner from a fixed point and cannot interact with the scene. Compared with true 3D display, the user experience is not ideal. The latter VR-based three-dimensional scene requires the support of VR glasses and other equipment, has high display costs and is not very practical.

[0048] like Figure 1 The present invention provides a method for implementing diversified display of home furnishings through three-dimensional models, which is applied to a diversified interactive display system of home furnishings, and includes a production-end implementation step and a display-end implementation step; in the production-end implementation step, the first step is to receive a user's preset operation on a newly created or existing three-dimensional scene model, and the second step is to respond to the preset operation and output a new three-dimensional scene model that has completed the preset operation, wherein the preset operation includes setting the skeleton animation parameters of a virtual object, setting the rotation parameters of an object, setting the extended object parameters, and setting a replaceable object list; in the display-end implementation step, the first step is to input a new three-dimensional scene model that has completed the preset operation, and the second step is to receive a simulation action operation instruction and execute the simulation action operation instruction, wherein the simulation action operation instruction includes instructions for virtual object walking, object display, extended object display, and object replacement; after completing a series of implementation steps, it is not only conducive to displaying the arrangement of each furniture model in the three-dimensional scene, but also enhances the diversified interactivity with the three-dimensional scene and improves the user experience.

[0049] To further illustrate, virtual objects include virtual humans, virtual robots, virtual dogs, etc.; objects include furniture models; and extended objects include star-shaped virtual objects for hiding in furniture models.

[0050] Preferably, the virtual object skeleton animation parameters include the walking path and speed of the virtual object.

[0051] Specifically, users use 3D model production software such as Blend or Max to create skeletal animation models in fbx or glb formats, and use the GLTFLoader library in Three.js to load the skeletal animation model in glb format into the 3D scene to achieve the skeletal animation effect of the virtual object; the user uses the mouse to manually draw a closed composite line segment as the movement path of the virtual object on the production end, and the distance the composite line segment moves each time the 3D scene is drawn is used as the movement speed. The mobility of the virtual object makes the 3D scene more vivid and realistic, making it easier for users to interact with the 3D scene.

[0052] Preferably, the rotation parameters of the object include the rotation axis, rotation center, switching direction, rotation speed and rotation angle of the cabinet door of the object.

[0053] Specifically, setting the rotation parameters of any one or more objects in the three-dimensional scene can ensure that the cabinet door can be rotated, which is conducive to the user to perform the operation of opening the cabinet door and further realize the interaction with the three-dimensional scene. Further explanation: the cabinet door opening direction can be the direction of clockwise or counterclockwise rotation around the rotation axis, the rotation speed is the angle of rotation of the cabinet door each time the three-dimensional scene is drawn, and the range of the rotation angle is from the initial door opening angle to the end door opening angle.

[0054] Preferably, the movement parameters of the object include the movement direction and movement amount of the sliding door and the internal drawer of the object. Specifically, moving the sliding door and the internal drawer can allow the user to better observe the internal structure of the cabinet.

[0055] Preferably, the extended object parameters include the number of extended objects, and the number of extended objects is randomly generated.

[0056] Specifically, the object has several cabinet doors, and several extended objects are randomly set in the cabinet according to a random number algorithm. The user can observe the number of extended objects in the cabinet by judging and clicking on the cabinet door. If the number of extended objects is 0, it means that the cabinet door has no extended data of the extended object; if the number of extended objects is greater than or equal to 1, it means that the cabinet door has extended data of the extended object. The extended data will be automatically saved in the back-end database of the home multi-interactive display system, so that the home multi-interactive display system can identify the extended data of the extended object and display the extended object on the front-end interface.

[0057] In one embodiment, the extended object is a star-shaped virtual object, 10 cabinet doors are set, 3 of which are randomly selected to have star-shaped virtual objects, and extended data hideStars is stored. When the cabinet door is clicked, the home multi-interactive display system recognizes that there is hideStars and the front-end interface will display the corresponding star-shaped virtual object.

[0058] Preferably, the replaceable object list includes objects storing extended information. Specifically, the replaceable object list includes objects storing extended information, which can effectively identify the model of each furniture model, and according to the model of each furniture model, the user can find furniture models of the same category as replaceable furniture models.

[0059] Preferably, the specific steps of virtual object walking are as follows:

[0060] Step S61: obtaining the walking path and speed of the virtual object, and calculating the number of times the virtual object is drawn along the walking path;

[0061] Step S62: Calculate the position and rotation angle of the current virtual object on the walking path according to the current drawing times and the walking speed of the current virtual object;

[0062] Step S63: Obtain the matrix of the current virtual object according to the obtained position and rotation angle.

[0063] In one embodiment, the virtual object is set as a virtual puppy. The user sets the walking path and speed of the virtual puppy at the production end. Specifically, the walking path is a closed triangular path with three points p1, p2, and p3 respectively. The distance dis1 from p1 to p2 corresponds to the line segment line1, the distance dis2 from p2 to p3 corresponds to the line segment line2, and the distance dis3 from p3 to p1 corresponds to the line segment line3. Then the sum of the distances disAll = dis1 + dis2 + dis3. During the modeling of the virtual puppy, the center point of the virtual puppy is placed at the origin, and the head is facing the positive direction of the x-axis. Based on the current walking speed speed and disAll of the virtual puppy, the user can calculate that the number of drawing times required for the virtual puppy to complete one lap of this path is drawCount = disAll / speed. Since the three line segments of the triangle are at different angles, it is necessary to calculate which line segment the current drawing count currentDrawCount is on. For example, if the current walked length of the virtual puppy is walkDistance = currentDrawCount * speed, and if walkDistance > dis1 and walkDistance < dis1 + dis2, then the virtual puppy is currently on line2, the rotation angle is the angle angle2 from p2 to p3, and the current position of the virtual puppy is on the connection line from p2 to p3, and the distance from p2 is (dis1 + dis2 - walkDistance). Based on the position and rotation angle of the virtual puppy, the current matrix matrix of the virtual puppy can be obtained. Every time the user draws a three-dimensional scene at the production end, the current matrix of the virtual puppy is updated, so that the virtual puppy bone animation effect can be achieved on the display end.

[0064] Preferably, the object display includes opening or closing the cabinet door of the object. Among them, the specific steps for opening the cabinet door are as follows:

[0065] Step S71: Obtain the rotation axis, rotation center, door opening direction, rotation speed, and rotation angle of the cabinet door;

[0066] Step S72: Calculate the total number of drawing times required to complete one operation of opening the cabinet door according to the rotation angle and rotation speed;

[0067] Step S73: According to the current drawing count, determine whether the current drawing count is greater than the total drawing count. If the current drawing count is greater than the total drawing count, calculate the current rotation angle of the current cabinet door;

[0068] Step S74: Obtain the rotation matrix of the current cabinet door according to the current rotation angle, rotation axis, and rotation center of the cabinet door.

[0069] In one embodiment, the user sets the rotation axis "axis", rotation center "center", rotation speed "speed", opening direction, and rotation angle "rotateAngle" of the cabinet door of the furniture model at the production end. The total number of times "drawCount" required to draw for one operation of opening the cabinet door is "drawCount = rotateAngle / speed". If the current number of draws is "currentDrawCount", then when "currentDrawCount < drawCount", the rotation angle "currentAngle" of the cabinet door is "currentAngle = currentDrawCount * speed". According to the current rotation angle "currentAngle", rotation axis "axis", and rotation center "center" of the cabinet door, the rotation matrix "rotateMatrix" of the current cabinet door is obtained. Every time the user draws the three-dimensional scene at the production end, the rotation matrix of the current cabinet door is updated, so that the effect of opening the cabinet door can be achieved at the display end.

[0070] Preferably, it includes the specific steps of object replacement:

[0071] Step S81: Identify the object storing the extended information and generate a list of replaceable objects;

[0072] Step S82: Receive the selection operation of the user from the list of replaceable objects;

[0073] Step S83: In response to the selection operation, receive the instruction to place the selected replacement object at the position of the original object and execute the placement instruction.

[0074] Specifically, during the placement process, the GLTFLoader library in Three.js is called to load the replacement object, and the replacement object is moved to the position of the original object to implement the replacement operation of the furniture model, enhancing the diversified interaction with the three-dimensional scene.

[0075] Further explanation, when generating the list of replaceable objects, when quoting, the system will automatically count the existing object list in the three-dimensional scene, perform a differential check with the original object list, and obtain the objects replaced by the user.

[0076] Another aspect of the present application provides a home diversified interaction display system, and the system includes

[0077] A receiving module, configured to receive the preset operation of the user on the newly created or existing three-dimensional scene model;

[0087] The fifth setting subunit is used to set a replaceable object list, where the replaceable object list includes objects storing extended information.

[0088] The simulation action operation module also includes a first simulation action operation sub-unit, which is used to realize the walking of the simulated object. Specifically, the walking path and speed of the virtual object are obtained in the sub-unit, and the number of drawing times required for the virtual object to walk along the walking path is calculated; according to the current number of drawing times and the current walking speed of the virtual object, the position and rotation angle of the current virtual object on the walking path are calculated; according to the obtained position and rotation angle, the matrix of the current virtual object is obtained;

[0089] The second simulation action operation subunit is used to realize the display of the object, and the object display includes opening or closing the cabinet door of the object.
