Abstract

PURPOSE: A method for managing asharing object in a virtual reality space is provided for enhancing a performance of a system by decreasing an overload of a server system and a communication between the systems of participants. CONSTITUTION: A distribution virtual reality system is classified based on a hierarchy by the number of server and client systems which form a distribution virtual reality system and forms a sharing virtual object(S101). A domain region needed for each field is computed from the hierarchial groups for identifying a region of the hierarchy classified in S101, and then an identification region for storing a corresponding identifier in accordance with a result of the computation(S102).

도 1은 본 발명의 일 실시예에 따른 가상 현실 공간 공유 객체 관리방법에 대한 처리 흐름도로서, 도 1을 참조하면, 다중 서버 다중 클라이언트 구조를 가지는 분산 가상 현실 시스템에 있어서 가상 현실 공간 공유 객체를 관리하기 위한 본 발명의 방법은 상기 분산 가상 현실 시스템을 구성하는 서버 시스템 및 클라이언트 시스템의 수에 의해 상기 분산 가상 현실 시스템을 계층적으로 구분하여 공유 가상 객체들을 형성하는 제 1 과정(s101)과, 상기 제 1 과정(s101)에서 구분된 계층의 영역을 식별하기 위해 상기 구분된 계층적인 그룹들로부터 각 필드에서 필요한 도메인 영역을 계산한 후 그에 따라 해당 식별자를 저장하는 식별 영역을 구분하는 제 2 과정(s102)과, 상기 제 2 과정(s102)에서 생성된 식별자 필드 및 도메인 영역의 형태로 각 클라이언트 시스템의 객체에 대한 식별자를 할당하는 제 3 과정(s103)과, 상기 공유 가상 객체에 대한 조작권을 관리하는 제 4 과정(s104)으로 구성된다.1 is a flowchart illustrating a method for managing a virtual reality space shared object according to an embodiment of the present invention. Referring to FIG. 1, a virtual reality space shared object is managed in a distributed virtual reality system having a multi-server multi-client structure. The method of the present invention provides a first process (s101) of forming the shared virtual objects by hierarchically classifying the distributed virtual reality system by the number of server systems and client systems constituting the distributed virtual reality system, and In the first step (s101), a second step of calculating a domain area necessary for each field from the divided hierarchical groups to identify the areas of the divided hierarchical groups and dividing the identification area storing the corresponding identifier accordingly ( s102) and each client system in the form of an identifier field and a domain region generated in the second process s102. A third process (s103) of allocating an identifier for the object of the object and a fourth process (s104) of managing an operation right for the shared virtual object.

도 2는 상기와 같은 과정에 의해 계층적으로 구분된 분산 가상 현실 시스템의 다중 서버 다중 클라이언트에 대한 시스템 구성도로서, 도 2를 참조하면, 상기 제 1 과정(s101)에서 계층적으로 구분된 서버 및 클라이언트 시스템의 구성예를 나타내는데, 'SGn'은 n번째 서버 시스템 그룹을 나타내는 것으로서, 도면에 나타난 'SG1(21)'은 1번째 서버 시스템 그룹을 나타내고, 'SG2(22)'는 2번째 서버 시스템 그룹을 나타내며, 'SG3(23)'은 3번째 서버 시스템 그룹을 나타낸다. 그리고, 상기 각 서버 시스템 그룹에 연결된 'Cnm'은 n번째 서버에 연결된 m번째 클라이언트 시스템을, 'O'는 각 클라이언트에서 사용하는 가상 객체, 실선은 통신망을 표시한다.FIG. 2 is a system configuration diagram of a multi-server multi-client of a distributed virtual reality system hierarchically divided by the above process. Referring to FIG. 2, the server hierarchically divided in the first process s101. And a configuration example of a client system, where 'SGn' represents an nth server system group, 'SG1 (21)' in the figure represents a first server system group, and 'SG2 (22)' represents a second server. 'SG3 (23)' represents the third server system group. In addition, 'Cnm' connected to each server system group represents an mth client system connected to an nth server, 'O' represents a virtual object used by each client, and a solid line represents a communication network.

한편, 상기와 같은 계층적 시스템을 구성하기 위해서는 도 3에 나타난 것과 같은 과정을 수행하는데, 도 3은 본 발명에 의해 분산 가상 현실 시스템을 계층적으로 분리하는 과정에 대한 처리 흐름도로서, 도 3을 참조하면, 상기 과정은 먼저, 초기 시스템의 구성시 사용하고 있는 통신망의 성능 및 교환되는 객체 데이터의 크기를 고려하여 가상 공유 공간 참여자에게 실시간 지원이 가능한 클라이언트 시스템 및 서버의 수를 미리 계산(s301)하고, 그 계산 결과를 바탕으로 서버 시스템(Sn)에 클라이언트 시스템(Cnm)을 할당하여 클라이언트 시스템 그룹을 형성(s302)한 후, 상기 서버 시스템(Sn)들을 묶어서 서버 시스템 그룹(SGn)을 형성(s303)하는 과정을 수행하며, 상기 과정을 반복 수행함으로써 서버 시스템 그룹(SGn)을 계층적으로 구성한다.Meanwhile, in order to configure the hierarchical system as described above, a process as shown in FIG. 3 is performed. FIG. 3 is a flowchart illustrating a process of hierarchically separating a distributed virtual reality system according to the present invention. Referring to the above, first, the number of client systems and servers capable of real-time support to the virtual shared space participant is calculated in advance in consideration of the performance of the communication network used in the initial system configuration and the size of object data exchanged (s301). Based on the calculation result, the client system Cnm is assigned to the server system Sn to form a client system group (s302), and then the server systems Sn are bundled to form a server system group SGn ( S303) is performed, and the server system group SGn is hierarchically formed by repeating the above process.

한편, 시스템 운용중 새로운 클라이언트 시스템이 연결되면 그 시스템의 물리적 위치 또는 가상 공간 안에서의 가장 근접한 위치에 있는 클라이언트 시스템 그룹으로 그 새로운 클라이언트 시스템을 연결한다.On the other hand, when a new client system is connected during system operation, the new client system is connected to the client system group in the physical location of the system or the closest location in the virtual space.

도 4는 본 발명의 가상 객체 식별자 구성에 대한 예시도로서, 도 4를 참조하면, 상기 구분된 영역을 식별하기 위한 식별 영역은 상기 구분된 계층적인 그룹들로부터 각 필드에서 필요한 도메인 영역을 계산한 후 그에 따라 서버 그룹 식별자(ID) 영역(31)과, 서버 식별자(ID) 영역(32)과, 클라이언트 객체 식별자(ID) 영역(33)으로 구분된다.FIG. 4 is an exemplary diagram for configuring a virtual object identifier of the present invention. Referring to FIG. 4, an identification area for identifying the divided area is calculated by calculating domain domains required for each field from the divided hierarchical groups. After that, it is divided into a server group identifier (ID) area 31, a server identifier (ID) area 32, and a client object identifier (ID) area 33.

이 때, 상기 분산 가상 공간에 참여하는 참여자는 상기 클라이언트 시스템을 사용하여 분산 가상 공유 공간에 참여하며, 어떤 클라이언트에서 가상 공간 안에 존재하는 객체를 움직이거나 변경하는 등의 객체에 대한 조작을 하려면 먼저 그 객체에 대한 조작 허가권(permission)을 가져야 하는데, 모든 객체에 대한 조작 허가권 부여는 객체를 소유한 클라이언트를 관리하는 서버에서 수행한다.At this time, the participant participating in the distributed virtual space participates in the distributed virtual shared space by using the client system, and if a client wants to operate an object such as moving or changing an object existing in the virtual space, You must have permission to operate on an object. Granting permission to all objects is done by the server that manages the client that owns the object.

또한, 상기 클라이언트 시스템과 서버에 대한 식별은 상기 식별 영역에 할당된 객체 식별자에 의해 가능하다.In addition, identification of the client system and server is possible by an object identifier assigned to the identification area.

상기와 같은 본 발명은 시스템을 계층적으로 재구성함으로써, 다수 참여자에 의해 공유되는 가상 공간 객체의 공유 처리시 서버 시스템에 발생하는 과부하 및 참여자 시스템간의 통신량을 줄이도록하며, 이로 인해 전체 시스템의 성능 저하를 줄일 수 있다는 효과가 있다.The present invention as described above, by hierarchically reconfiguring the system, to reduce the overload occurring in the server system and the communication between the participant system in the process of sharing the virtual space objects shared by multiple participants, thereby reducing the performance of the entire system There is an effect that can be reduced.
