Embodiments of the present invention will be described with reference to the drawings. First, an information providing device (computer) will be described. FIG. 1 is a block diagram of an information providing device (computer). In FIG. 1, 1 is a computer main body, 2 is a display, 3 is a keyboard, and 4 is a mouse.

The computer body 1 includes an FD drive 5,
It has a CD ROM drive 6, a CPU 7, and a hard disk 8. The program for operating the information providing apparatus is FD (Floppy Disk) 9 or CDROM 1
0 and provided. Then, the stored program is read by the FD drive 5 or the CDROM drive 6 and installed on the hard disk 8.

Next, a specific operation will be described. still,
Here, a model in which two triangular pyramids overlap will be described. First, launch the installed program. Next, a file (bac file) of the model created by a predetermined modeler is opened. Then, one model is divided into a plurality of polygons constituting the model, and each polygon is divided into planes constituting the polygon. still,
Hereinafter, the divided polygons are referred to as bones.

FIG. 2 shows the divided Bone 1 and Bone 2
3 is an image of a surface that constitutes. These displayed surfaces have identification numbers (0, 1, 1) for identifying the surfaces for each bone.
2, 3) and identification symbols (a, b,
c) is attached. Further, the original polygon is also displayed on the screen, and the identification number and the identification symbol corresponding to the vertex of the surface are also displayed on the surface of the displayed polygon. FIG. 3 is a diagram in which the original polygon is three-dimensionally displayed.

As can be seen from FIGS. 2 and 3, the identification number of each surface and the identification symbol corresponding to the vertex of each surface are displayed in correspondence with each other. That is, when a bone is decomposed into surfaces, an identification number for identifying the surface and an identification symbol for each vertex are given in consideration of the connection between the surfaces. Subsequently, on the screen shown in FIG. 2, the surfaces are connected while dragging the surfaces. That is, a development view is created. At this time, since the original bone (polygon) shown in FIG. 3 is displayed in three dimensions, a development view is created while confirming the connection relationship by looking at this screen. Note that the connection (position) relationship between the top, bottom, left and right is confirmed by the identification symbol attached to the vertex of each plane. Further, since the positional relationship of the plane cannot be determined only by one three-dimensional figure, a three-dimensional figure viewed from various angles can be displayed. FIG. 4 is a three-dimensional display of the case in which the figure of FIG. 3 is viewed from another angle.

In this manner, each polygon is developed into a developed view. Note that a three-dimensionally displayed Bone surface may be dragged and dropped to create a development view.

According to the present invention, by developing a three-dimensional model, the texture of the three-dimensional model can be easily pasted.
