[0081] EXEMPLARY EMBODIMENTS

[0082] Figure 1A flowchart of one embodiment of a method for displaying a virtual object in a three-dimensional scene of the present disclosure; the method for displaying a virtual object in a three-dimensional scene can be applied on an electronic device (such as a computer system, a server), as shown in Figure 1 The method for displaying a virtual object in a three-dimensional scene can include the following steps:

[0083] In step 101, in response to receiving a task of adding a mixed reality model, a target model to be added is added to a three-dimensional scene, obtaining a target three-dimensional scene containing the target model.

[0084] The task of adding a mixed reality model refers to a task of adding an MR model in a virtual reality (VR) three-dimensional scene.

[0085] In some embodiments, the present disclosure provides two ways to trigger the task of adding a mixed reality model. One is to trigger the task of adding a mixed reality model through a client interface interaction method, that is, to trigger the task of adding a mixed reality model through an adding operation of a mixed reality model triggered by a user in a virtual reality client interface. The other is to trigger the task of adding a mixed reality model through an algorithm method, that is, to trigger the task of adding a mixed reality model when a task manager receives an adding task of a mixed reality model detected by a task scheduling system.

[0086] The two ways of triggering the task of adding a mixed reality model in the above examples can be applied in different scenarios of adding an MR model. The client interface interaction method can be applied in a scenario of adding an MR model in a single VR three-dimensional scene or a small number of VR three-dimensional scenes. The algorithm method can be applied in a scenario of adding an MR model in a large number of VR three-dimensional scenes, for example, adding a sofa MR model in thousands of indoor spaces. In this case, a task can be input in the task scheduling system. The task information can indicate in which VR three-dimensional scenes to add an MR model, the identification information of the target model to be added, and the placement position.

[0087] In some embodiments, after receiving the task of adding a mixed reality model, the target model to be added can be determined according to the task information of the task, and a target three-dimensional scene containing the target model is obtained.

[0088] The target model is an MR model, which can be a static MR model or a dynamic MR model. The storage format of the MR model can be an obj model or a glb model.

[0089] The implementation of adding a target model through a client interface interaction method can refer to the embodiment shown in Figure 2A The implementation of automatically adding a target model through an algorithm method can refer to the embodiment shown in Figure 3In the illustrated embodiment, no further details are given here.

[0090] In step 102, a preset light is added to the target model in the target three-dimensional scene.

[0091] In some embodiments, the preset light can be a fixed High Dynamic Range (HDR) light, which can be directly displayed in the target three-dimensional space to achieve simplicity.

[0092] In some embodiments, the preset light can be the ambient light at the placement position of the target model in the three-dimensional scene. The ambient light at the placement position of the target model in the three-dimensional scene can be extracted by an algorithm, and then the ambient light is added to the target model in the target three-dimensional scene.

[0093] After determining the preset light, the preset light can be added to the target model in the target three-dimensional scene in a manner known in the art.

[0094] In step 103, the target three-dimensional scene is rendered and displayed.

[0095] The VR three-dimensional scene is rendered and displayed, which can more realistically display the effect.

[0096] The above steps 101-103, after receiving the task of adding a mixed reality model, automatically add the target model to be added to the three-dimensional scene, then add a preset light to the target model in the target three-dimensional scene, render the target three-dimensional scene, and display the real virtual object effect in the virtual reality three-dimensional scene. The technical solution of the present disclosure can realize the addition of a target model in a collected real three-dimensional space for interaction and display, optimize the display effect of the target model in the real three-dimensional space model by adding a preset light to the target model, and achieve a realistic virtual-real fusion effect.

[0097] To better illustrate the scheme of the present disclosure for displaying virtual objects in a three-dimensional scene, another embodiment is described below.

[0098] Figure 2A A flowchart for implementing a mixed reality model display in a three-dimensional scene through an interactive manner in an embodiment of the present disclosure, Figure 2B A schematic diagram for adjusting the placement properties of a mixed reality model in a three-dimensional scene in the present disclosure Figure 1 , Figure 2C A second schematic diagram for adjusting the placement properties of a mixed reality model in a three-dimensional scene in the present disclosure; this embodiment is exemplarily described by taking how to add a mixed reality model in a three-dimensional scene through an interactive manner as an example, as Figure 2A shown, comprising the following steps:

[0099] In step 201, in response to receiving the adding operation of adding a mixed reality model triggered by the user in the virtual reality client interface, it is determined that the task of adding a mixed reality model is received.

[0100] In some embodiments, in order to implement the technical solutions of the present disclosure, a VR editor function module for adding an MR item can be set in advance in the VR space rendering software, so that the user can trigger the adding operation of adding a mixed reality model through an interface button or operation command on the virtual reality client interface.

[0101] In some embodiments, the adding operation can indicate the target model to be added, for example, can include the identification information of the target model.

[0102] In step 202, the target model to be added is determined according to the adding operation.

[0103] Among them, a large number of MR models can be obtained in advance in the network server, for example, the MR models can be downloaded in some public website servers, and then the downloaded MR models can be uploaded to the local server. When it is needed to add an MR model, the effect diagram of a group of MR models can be displayed through the virtual reality client interface, and the user can select to use through the adding operation.

[0104] In step 203, the target model is placed in the three-dimensional scene.

[0105] In some embodiments, the MR model can be adsorbed and the position can be selected through a mouse; or the placement position information of the MR model can be set through the client operation interface when the adding operation is triggered, for example, the placement position is set as the floor.

[0106] In step 204, the adjustment operation triggered by the user in the virtual reality client interface is received.

[0107] In some embodiments, after the target model is placed, the adjustment operation can be triggered in the virtual reality client interface to adjust the size, position and angle of the placed MR model.

[0108] Among them, the adjustment operation can be an adjustment operation triggered in the attribute setting window displayed in the virtual reality client interface; or an adjustment operation triggered in the panorama and / or three-dimensional model page displayed in the virtual reality client interface, see Figure 2B and Figure 2C .

[0109] In some embodiments, the attribute setting window can be an independent window triggered by an attribute setting command, or can be a region window displayed on the panorama interface, see Figure 2B andFigure 2C The properties settings window on the right.

[0110] In panoramic mode, you can directly drag the MR model with the mouse in the panoramic image to adjust its position, size, and angle; you can also adjust the position, size, and angle of the MR model in the corresponding property settings window.

[0111] In the 3D model mode, you can directly view the effect of the MR model in 3D space on the 3D model page, and then trigger adjustment operations on the 3D model page.

[0112] In step 205, the target model is placed according to the adjustment operation.

[0113] In some embodiments, after placing the model, a target three-dimensional space containing the MR model can be stored, and the attribute information of the MR model in the target three-dimensional space, including position, size, and angle, can be recorded.

[0114] By switching between the 3D model mode and the panoramic mode, and making adjustments from multiple angles, the optimal placement effect of the MR model in 3D space can be achieved.

[0115] Figure 3 This is a flowchart illustrating an implementation of the algorithmic display of a mixed reality model in a 3D scene according to this disclosure. This embodiment uses the example of adding a mixed reality model to a 3D scene using an algorithm as an example for illustrative purposes. Figure 3 As shown, it includes the following steps:

[0116] In step 301, in response to receiving a mixed reality model addition task in the task manager, it is determined that a mixed reality model addition task has been received.

[0117] In some embodiments, for scenarios where MR models need to be added to a large number of VR scenes, a task can be generated in advance in the task scheduling system for each VR scene. The task includes the indication information of the MR model to be added, the VR scene to be added, and the addition location, which is used to instruct the task scheduling system to trigger the task at a specified time point and add the task to the task manager for execution.

[0118] In step 302, the target model to be added, the 3D scene, and the placement position are determined based on the task information of the added task.

[0119] In some embodiments, task information may indicate the VR 3D scene where an MR model needs to be added, the MR model to be added, and its placement.

[0120] The user can select a position as the placement position from preset positions such as a floor, a sofa, a bed, and the like, and the operation is simple and fast; the user can also customize a position as the placement position in the three-dimensional scene, so that the placement position is more in line with the user's preference habit.

[0121] In some embodiments, after receiving the task of adding the mixed reality model, the target model to be added can be determined according to the task information of the task, and a target three-dimensional scene containing the target model is obtained.

[0122] In step 303, the target model is placed at the placement position of the three-dimensional scene.

[0123] In some embodiments, if the placement position is a sofa, the MR model can be automatically placed on the sofa, such as in the middle position of the sofa.

[0124] In order to realize the placement of the MR model, the placement position in the three-dimensional scene needs to be identified by a model recognition algorithm first, for example, if the placement position is a sofa, the sofa needs to be identified in the three-dimensional scene first, and then the placement of the MR model is performed.

[0125] In step 304, the position of the target model is iteratively adjusted by a mesh collision detection algorithm.

[0126] In some embodiments, after the MR model is placed at the placement position indicated by the task, the mesh collision detection algorithm can be further used to detect whether collision or penetration occurs between the MR model and the placement position, and if collision or penetration occurs, the position of the MR model can be adjusted, and then the mesh collision detection algorithm is used to detect whether collision occurs, so as to iteratively adjust the position of the target model to a suitable position.

[0127] Through steps 301-304, the batch addition of the MR model can be realized by an algorithm, and the position of the MR model is iteratively adjusted by the mesh collision detection algorithm to avoid collision or penetration, so that the placement effect of the MR model in the three-dimensional space can be optimized.
