The attribute relationship determination unit 42 uses the attribute relationship determination table shown in FIG. 7 from the acquired next media attribute “OBJHIS020101” and the current media attribute “OBJHIS010101”, and the hierarchy of each appearance model is the same (i = j ), The attribute relation information of “association” is determined (step S33). The attribute relationship confirmation unit 42 sets the attribute relationship information “related” to the visual effect setting unit 25.
To end the attribute relationship determination process.

The visual effect setting section 25 performs the following visual effect setting processing using the "related" attribute relationship information acquired from the attribute relationship determining section 42 (step S4).

In the visual effect setting process, the visual effect type selection unit 53 acquires the attribute relation information of "related" (step S41). The visual effect type selection unit 53 has the attribute relationship shown in FIG.
The visual effect correspondence table is used to select the "fade in / fade out" visual effect type corresponding to the "related" attribute relationship information (step S42).

The visual effect determination section 54 analyzes the usage history of the visual effect history currently stored in the display state storage section 24, and selects three "fade in / fade out""slow, medium speed, fast". Of the patterns that have not yet been used, or are the oldest used in time, "slow, fade-in /
"Fade out" is confirmed (step S43). The media expression switching unit 55 reads out the visual effect realization method information stored in the visual effect library 52 in accordance with the visual effect pattern of "slow, fade-in / fade-out", and generates state change control information (step S44).

The media expression switching unit 55 indicates "slow,
The visual effect of "fade in / fade out" is stored in the history of the current display state storage unit 24 (step S45). The media representation switching unit 55 supplies the generated state transition control information to the three-dimensional space visualization unit 13, and ends the visual effect setting process.

The spatial image generation unit 14 acquires the three-dimensional space information generated by the three-dimensional space visualization unit 13 according to the state conversion control information supplied from the visual effect setting unit 25, and "slow, fade-in / fade-out". A space image that gives the appearance of an old model car with the visual effect of is generated (step S5). As a result, the display unit 15
Switches from the appearance of the new model car shown in FIG. 14 (a) to the appearance of the old model car shown in FIG. 14 (b) while displaying the "slow, fade in / fade out" visual effect.

Next, when the external appearance of the new model car shown in FIG. 14A is displayed on the display unit 15, the user operates a sensor device such as a mouse to operate the new model car shown in FIG. 14C. 14 (d) when the structure of FIG. 14 (d) is selected or when the appearance of the old model car shown in FIG. 14 (b) is displayed.
A case will be described in which the structure of the old model vehicle shown in is selected.

In this case, since the hierarchy of the appearance model and the structure model is the same (i = j) in the attribute relationship determining unit 42,
The attribute relation information "is-a" is selected, and "wipe out" is selected in the visual effect type selection unit 53. As a result, the display unit 15 displays, for example, in FIG.
From the appearance of the new model car shown in (a), while displaying the visual effect of "wipe out in the x-axis direction", FIG.
The display is switched to the structure of the engine of the new model shown in (c).

Next, when the appearance of the new model car shown in FIG. 15 (a) is displayed on the display section 15, the user operates a sensor device such as a mouse to operate the new model car shown in FIG. 15 (c). When the external appearance of the engine is selected, or when the external appearance of the new model shown in FIG. 15 (a) is displayed, the user selects the external appearance of the tire of the new model shown in FIG. 15 (d). explain.

In this case, since the hierarchy of each appearance model is different (i <j) in the attribute relationship determining unit 42, “par”
The attribute relation information “t-of” is selected, and “zoom in” is selected in the visual effect type selection unit 53. As a result, the display unit 15 displays, for example, the appearance of the tire of the new model shown in FIG. 15D while displaying the visual effect of “fast, zoom in” from the appearance of the new model shown in FIG. Switch.

As described above, since the media attributes such as the form and hierarchy of the media are digitized and stored in advance in the attribute relationship table, the value of the media attribute currently displayed and the value of the media attribute displayed next time. From this, it is possible to automatically interpret the inclusion relation between media of the current display screen and the next display screen. Therefore, it is not necessary to individually define the relationship between media that can switch screens, and it is easy to create and maintain new content using objects.

In addition, an effective visual effect is automatically determined when switching from the current display screen to the next display screen based on the attribute relationship between the currently displayed media attribute and the media attribute to be displayed next time. You can Therefore, it is not necessary to individually define the relationship between media that can switch screens, and it is easy to create and maintain new content using objects.

Further, since the use history information of the visual effects is stored and used, a plurality of visual effects having individually different display effects can be managed as an aggregate, which is effective when switching the display screen. Visual effects can be automatically selected.

In the above embodiment, the object of the automobile composed of the appearance model, the structural model and the function model has been described as an example, but the object to be displayed is arbitrary. Further, the structure of the object is not limited to the appearance model, the structural model, and the functional model, and may be any attribute that the object to be displayed has.

The three-dimensional spatial media information display device of the present invention can be realized by using an ordinary computer system instead of a dedicated system. For example, a medium (a floppy disk, a CD-ROM, etc.) storing a program for executing any of the above in a computer.
By installing the program from, it is possible to configure a three-dimensional spatial media information display device that executes the above processing.

The medium for supplying the program to the computer may be a communication medium (a medium that temporarily and fluidly holds the program, such as a communication line, a communication network, a communication system). For example, the program may be posted on a bulletin board (BBS) of a communication network and distributed via the network. Then, the above process can be executed by starting this program and executing it under the control of the OS in the same manner as other application programs.
