PROBLEM TO BE SOLVED: To share three-dimensional virtual space information for enabling load distribution complying with loads of terminals with different performance on a large-scale network and seamless cooperation between the terminals on the network. SOLUTION: This communication device comprises a 3D virtual space sharing part sharing the three-dimensional virtual space information between a plurality of units, an operation information input part for operating a viewpoint position, an object shape, and an object position inside the space with intention and autonomy of an operator, a unit cooperation part for transmitting/receiving shared data between a first unit and a plurality of other sharing servers sharing the three-dimensional space or between a plurality of units among a plurality of units, and a curved face processing part for defining the object inside the space with curved faces and performing conversion to polygon data necessary for drawing according to control point information of the curved faces for drawing the object. The communication device further comprises a unit management part for performing management/reporting information of the conditions of a plurality of units sharing the space in a real time.
