First, the technical concept used in the present invention will be described. First, VRML, a language for realizing a three-dimensional virtual space on the Internet, will be described in order to facilitate understanding of the present invention.

VRML is a language specification for displaying a three-dimensional virtual space, which makes it possible to realize a virtual space of the Internet hyperlinked on the WWW by this language. VRML files consist of hierarchical scenegraphs and nodes, using 7-bit ASCII code. The coordinate system used in VRML is righthanded (x-axis: up, y-axis: right, -z-axis: forward), and is relatively defined by separator, world space, and object space.

In addition, three-dimensional diagrams that are easy to express scenes are cubes, spheres, cones, cylinders, etc., and the functions for transformation in three-dimensional space include translation, rotation, Scale and the like are provided.

Meanwhile, browsers for various platforms have been created. A typical VRML browser is a webspace jointly developed by SGI and TGS. Webspace supports Examiner Viewer mode for rotating 3D objects and Walk Viewer mode for walking through shopping malls.

In addition, three-dimensional web browsers that allow users to view a flat Internet homepage in three dimensions are being released one after another. A three-dimensional web browser is a program that allows users to literally view three-dimensional, exciting three-dimensional images on the Internet web. It's easy to install and use in Netscape.

Most of these programs are provided in the form of flags, and when VRML is used to access a site where a 3D homepage is opened, the 3D image that overcomes the limitation of the plane can be viewed. Three-dimensional web browsers are excellent for viewing 3D chat rooms, virtual worlds, and 3D special effects scenes.

In other words, it allows you to see objects modeled in three dimensions. In addition, realistic 3D objects can be effectively used in virtual walkthrough and game fields. The most representative three-dimensional search tools are Web FX, Web Interactive Reality Layer (WIRL), and Topper.
