Here, the 3D object for the meeting may be a 3D modeling resource (3D Model resource) to be discussed by users in the corresponding VR meeting. For example, if the product to be discussed in a VR meeting is a new model car, the 3D object for the meeting may be a 3D modeling resource for the vehicle. Alternatively, if the product to be discussed in the VR meeting is a new model mobile phone, the 3D object for the meeting may be a 3D modeling resource for the mobile phone.

Thereafter, the server 110 may reflect at least one conference 3D object in the virtual conference room (S204).

At this time, the server 110 may perform predefined rendering on the 3D object according to the characteristics and requirements of the virtual meeting room. Predefined renderings can include colors, textures, lighting tones, etc. depending on the virtual meeting room. Through this, 3D objects included in the virtual meeting room can be presented without looking unnatural.

At this time, the user accounts 161-163 can log in from the user terminals 131-133 and access the virtual conference room through the virtual conference platform 140, and the server 110 can access the virtual conference room using user accounts ( 161-163) can be rendered as a user avatar.

For example, the user avatar may be a 3D humanoid avatar capable of performing actions such as moving, looking around, talking, and making selections. Additionally, the appearance of the user avatar may be modeled or characterized based on real-life images, or may be customizable.

Thereafter, the server 110 may perform the predefined interaction of the corresponding user interaction element when each user avatar in the VR meeting performs an action that matches the predefined action of at least one user interaction element. There is (S206).

Here, the predefined actions of the user interaction element may include various actions. For example, when clicking on another user avatar, chatting with the user account of that user avatar may be possible.

Meanwhile, in the present invention, the predefined actions of these user interaction elements are linked to 3D objects for meetings.

That is, when a user avatar selects and points to a specific location on a 3D object for a meeting, the server 110 selects the specific location on the pointed 3D object to the user terminal 131 where the user account 161-163 is logged in. -133) Send it to everyone and share it.

Hereinafter, FIGS. 3 to 5 will be described for the operation of the server 110 of the present invention transmitting and sharing a specific location on a pointed 3D object to all user terminals 131-133 to which user accounts 161-163 are logged in. Please refer to and explain.

First, the raycasting technique used in the present invention will be described with reference to FIG. 3. Figure 3 is a diagram to explain the principles of the raycasting technique used in the present invention to measure the specific position of a 3D object.

In the present invention, raycasting technique is used to obtain coordinates in virtual three-dimensional space. Raycasting is a technique that projects invisible light (ray) into a virtual space and identifies the surface that the light touches.

In other words, raycasting is performed from the screen touch point touched by the user to the forward direction the camera is looking at, and the collision point is based on the 3D object. ) Measure the coordinates. The coordinates are three-dimensional coordinates in space and can be expressed as (x,y,z).

In the present invention, through this, the coordinates of the location indicated by the user on the surface of the 3D object are obtained and the information is transmitted to the server 110 and delivered to other users. At this time, a predetermined effect can be created and displayed at the coordinates of the location indicated by the user on the surface of the 3D object. For example, a predetermined effect may be a laser point display.

In addition, the present invention can provide information on which user generated the event by connecting the user avatar who generated the event at the corresponding coordinates in virtual space and the point of occurrence with a line.

Next, with reference to FIGS. 4 and 5 , a method for sharing a specific location indication on a 3D object in virtual space will be described in the present invention.

In addition, Figure 5 is an operation flowchart showing an operation of sharing a specific location indication of a 3D object in a real-time VR conference system capable of sharing a specific location indication on a 3D object in a virtual space according to an embodiment of the present invention.

First, when a specific location on a 3D object is touched on the user terminal of a user (User 1), the coordinates (x, y, z) corresponding to the specific location on the 3D object are measured and stored (S510).

At this time, User 1 may be a user located in Korea, as shown in FIG. 4.

In the present invention, the method of measuring coordinates (x, y, z) corresponding to a specific position on a 3D object applies the raycasting technique of FIG. 3 as described above. In other words, raycasting is performed from the touch point of the screen touched by the user to the forward direction where the camera is looking, and the collision point is based on the 3D object. ) Measure the coordinates. At this time, the coordinates are three-dimensional coordinates in space and can be expressed as (x,y,z).

Next, User 1's user terminal transmits the 3D coordinates (x, y, z) in the stored space to the server 110, and the server 110 receives and stores them (S520).

Afterwards, the server 110 transmits the received spatial 3D coordinates (x, y, z) to other users (User 2 and User 3) who are sharing the 3D object (S530). At this time, User 2 and User 3 may be remote users located in LA, USA, as shown in FIG. 4.

Subsequently, the user terminals of other users (User 2 and User 3) that have received the 3D coordinates (x, y, z) in the corresponding space output and display them based on the anchor of the 3D object (S540). At this time, a laser point display can be used as an example of a display method.

Additionally, the present invention can provide information on which user generated the event by connecting the user avatar that generated the event to the coordinates and the point of occurrence with a line.

In the present invention as described above, 3D coordinates (x, y, z) values in space can be displayed as pixel values of 3D objects, so they can be displayed accurately without error, and this allows users of VR meetings who are far away. However, multiple users can accurately share a specific location indication on a 3D object in a virtual space that one user is referring to.

The real-time VR conference system and method for sharing a specific position indication on a 3D object in a virtual space of the present invention of the above-described configuration allows multiple users to accurately share a specific position indication on a 3D object in a virtual space. By doing so, communication between users in non-face-to-face meetings can be facilitated. In addition, the convenience and efficiency of the VR conference system can be improved by facilitating communication between users in non-face-to-face meetings by sharing specific location indications on 3D objects in a virtual space accurately in real time with multiple users.
