ABSTRACT:
A method of controlling users in a multi-user virtual space and a system for controlling users in a multi-user virtual space. The method includes the steps of: a) connecting lines formed by vertically and equally dividing lines obtained by connecting fixed points, which are center points of fixed objects in a three-dimensional virtual space, to partition the space into sub-spaces; b) calculating the distance between the position of a new user and fixed points of each partitioned sub-space and distributing the new user to the partitioned sub-space having the shortest distance; c) checking and controlling positions, movement and rotation information of each user; and d) repeatedly checking whether there is a new user, and repeating steps b) and c) when there is a new user. Accordingly, the three-dimensional virtual space is partitioned around a fixed point irregularly arranged in the virtual space, and users are assigned to a sub-space and a server according to the distance between the fixed point and the user. Therefore, when users move, the amount of calculation required to determine activities such as whether collisions have occupied is reduced and at the same time more users can take part in the system.
