As a result of performing a comparing and determining process of determining the relationship among the bandwidth of distributed data in real time in a local group, the incoming data bandwidth to the local group, and the outgoing data bandwidth from the local group, the increase/decrease management and the connection management of each terminal device in the local group are performed. The comparing and determining process compares, for example, a sum of the total sum of the terminal possessed transfer bandwidths and the incoming data bandwidth from other groups to the local group with a sum of the value obtained by multiplying the bandwidth of distributed data in the local group by the number of terminal devices in the local group, the outgoing data bandwidth from the local group, and a predetermined determination margin.

A group management device determines a priority level that represents priority order of allowing a participating terminal to preferentially participate in a group, to which the group management device belongs, based on information relating the participating terminal and information relating to terminals that are managed by the group management device only in a case where the group management device receives information relating to the participating terminal, which has transmitted a participation request to the group, to which the group management device belongs. Based on the determined priority level, the group management device determines whether to transmit the participation request to another group management device and whether to reply to the participating terminal.

In a multicast distribution system in which terminal devices on a distribution path are hierarchically grouped, a first terminal device which has detected a loss of a receiving packet transmits to a second terminal device located upstream of the first terminal device a retransmission request for a packet retransmission to the first terminal device and a third terminal device which receives a packet first in a group located downstream of a group to which the first terminal device belongs. The second terminal device which has received the retransmission request transmits a retransmission packet to both the first and third terminal devices.

An apparatus for determining whether polygons which form objects defined by graphic data generated by CAD intersect with virtually generated light rays. Polygons which are not intersected are removed from the graphic data as unnecessary for the generation of CG data. An apparatus is also described in which path passage points which pass through an animation path within a virtual world are interactively set. If an object exists that interferes with a path that joins adjacent path passage points, an alternate route path which detours around the interfering object is generated. An apparatus is also described in which a path of a moving object is interactively set on a perspective view of the virtual world as viewed from one direction. The position of the set path in the virtual world is calculated, and the position of the path in the direction of viewing is corrected to a position that is removed from an object by a prescribed distance.

A computer graphics apparatus includes a walk-through function to simulate with a computer the concept of walking through a structure such as a building. Display processing time and calculation processing time for one frame of a computer graphic image are improved by an input unit which receives a viewline moving instruction to move a viewline of a computer image. A viewline control unit determines positions and directions of the viewline while a storage unit stores computer graphics data including three-dimensional data of objects, walk-through attribute data and viewline data. An image generation unit then generates images including animated images based on the position of the viewline and the computer graphics data. The resultant images are then displayed on an image display unit.
