Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention describes and builds a 3D chat space in a chat-only 3D space description language,
The present invention relates to a 3D chat space construction system and method, and a 3D chat space construction program.

[0002]

2. Description of the Related Art 3D (3D) chat is one of the technologies created by combining the Internet, which has made rapid progress in the 90's, and computer graphics. 3D chat is for internet users via a character called an avatar,
It is a technology for providing a multi-user type three-dimensional space.

Normal three-dimensional CG (Computer Graphics)
The outline of the procedure for creating a spatial object by the production system is as follows. That is, first,
Create an outline of the space layout, add "height information" of the wall surface to the outline, and create a wall surface. Next, texture information such as texture and wallpaper is added to the wall surface, and polygon data and texture information are stored as data. The above is an outline of a method of creating a three-dimensional object by a general commercially available three-dimensional CG production system. When processing this for the above-mentioned 3D chat, it is necessary to convert the stored data by some method. Yes,
Since there are many restrictions in the chat-only 3D space description language, the burden of data conversion was heavy.

On the other hand, the 3D chat space is dedicated to chatting 3
When written in the D space description language, although there are quite a number of technical restrictions on expression, the processing by the computer is light, the operation is very fast and stable, and much bandwidth is required for the network. There is an advantage of not doing it. FIG. 9 shows a basic process until the 3D chat system is generated and executed. That is, the program source 91 programmed by the programmer is subjected to binary conversion by the text compiler 92 and provided to the interpreter 93. On the other hand, for images and sounds designed by the CG creator using the chat-specific 3D space description language, folders 96, 97, 98, and 99 are generated via respective compilers (image compiler 94 / sound compiler 95). , To the interpreter 93. This interpreter 93
Then, an executable file that can operate in the environment of the target user terminal (which executes chat) is generated and output.

[0005]

As described above, according to the prior art, when a chat space is designed by using a general three-dimensional CG production system, the produced three-dimensional object is three-dimensional.

In the case of designing by language, the CG creator and the pragma must use both the above-mentioned dedicated development language and perform both the space construction work and the programming work. According to the latter, the chat-specific 3D space description language is not a general programming language for purchasing manuals at bookstores,
Since it is a programming language developed by a specific manufacturer, it is necessary to train the CG creator and programmer on the language in order to perform the production work. Of course, there are difficulties in designing and ordering outside the company. In addition, since developmental factors are greatly involved in all production work, the cost of production cannot be ignored and it is difficult to reduce the schedule.
