[0007]

Embodiments of the present invention will now be described in detail with reference to the drawings.

(1) First Embodiment First, FIG. 1 is a block diagram showing a configuration according to a first embodiment of the present invention. The configuration according to the present embodiment will be described with reference to FIG.

The input means 1 provides a means for allowing a user to perform an input for operating a turning shape creation unit 4 described later. For example, a pointing device such as a mouse or the like often used for operation of a computer or the like is provided. A keyboard or the like corresponds to the input unit 1.

The data recording section 3 is a recording section for recording data to be displayed on display means or the like of a computer.

The turning shape creating unit 4 is a turning shape creating unit that creates a turning shape based on a user operation input via the input unit 1 and data in the data recording unit 3. The “turning shape” mentioned here will be described later in detail.

The turning shape creating section 4 further includes two components, a turning shape calculating section 7 and a turning shape drawing section 8.

The turning shape calculation unit 7 determines a function having an appropriate turning shape based on the designation of the input means 1.
The function is arbitrary, and for example, a sin curve having the current cursor position as a vertex can be considered.

The turning shape drawing unit 8 draws a turning shape according to the function determined by the turning shape calculation unit 7. It also performs processing such as pasting the original texture along the flipped surface.

The display control section 5 is a control section for controlling the display means 6 based on the data recorded in the data recording section 3 and the turning shape created by the turning shape creating section 4. More specifically, the display control unit 5 performs processing such as integrating an image of a turned-over surface with an image of a non-turned-down surface.

The display means 6 is a means for displaying based on an instruction from the display control unit. For example, a CRT or an LCD corresponds thereto.

The operation of the first embodiment of the present invention thus configured will be described with a specific example. FIG. 2 shows a specific example used in this description. This figure 2
Is used to simultaneously represent time and space by assigning a time axis in the vertical direction and stacking maps of each era. This example spatially targets the Kinki region, and temporally targets from the Nara era to the Heisei era.

In FIG. 2, the uppermost layer expresses a map of the Heisei era, and icons of buildings are arranged in the center. The second layer from the top shows the Showa period. The third layer from the top shows the Edo period. In the following, it is assumed that the era goes back to the lower hierarchy. For example, as shown in FIG. 2, the initial state is a state where the sheet is not turned at all.

In the state shown in FIG. 2, although the entire image is known, each layer of the map has many hidden parts that cannot be seen. For example, suppose the user wants to see the Showa era data well. In this example, the user uses the input unit 1 to
Grasp the edge of the layer 21 in FIG.
Can be dragged. The pointing position information in the input unit 1 is sent to the turning shape calculation unit 7 of the turning shape creation unit 4.

The turning shape calculation unit 7 calculates the position coordinates of each point on the surface so as to form a curved surface that draws a sin curve with the position of the cursor pointer as a vertex, for example, and sends it to the turning shape drawing unit 8. . In this example, for example, when the maximum height of the turning surface is H, the width of the turning surface is W, and the coordinates of each point on the turning surface are (x, h), the coordinates of each point are h = H × sin (( x × π) / W) (FIG. 3).

Next, the turning shape drawing unit 8 draws a turned surface based on the position coordinates of each point. At this time, processing such as distortion of the texture of the turned surface is also performed. Icons and objects existing on the turned surface are also drawn so as to be located along the surface.

The display control unit 5 integrates the information of these turned and unturned surfaces and finally displays the information on the display unit 6. FIG. 4 shows the state after turning over. In the second hierarchy from the top, that is, in the hierarchy of the Showa era, a high school baseball icon 41 of the Koshien Stadium is arranged slightly to the left of the screen. In this example, it is assumed that the user clicks this icon to jump to data and scenes related to high school baseball.

As described above, by turning over, a hidden portion that cannot be seen can be seen by a simple operation without changing the viewpoint.

The surface can be turned over in a plurality of layers. An example in that case is shown in FIG. By turning multiple data together, it is possible to simultaneously view data from the Heisei era and the Nara era, which are separated on the screen.

The shape of the turning surface is not limited to the sin curve described above. Any free-form surface or a combination of a plurality of planes may be used.

The turning direction is also arbitrary. FIG. 6 shows an example of turning to the front side.

In this embodiment, an example in which the time axis is allocated in the vertical direction has been described. However, as long as the time axis is three-dimensionally expressed, the target is arbitrary, and the time axis is always allocated in the vertical direction. No need.

For example, FIG. 7 shows an example applied to a three-dimensional building. This example is an example of a three-storey bookstore building. On the first floor, there is a sales floor for magazines, new books, paperbacks, etc., and on the second floor, there is a sales floor for books related to movies, art, music, etc. On the third floor, there is a sales floor for textbooks, dictionaries, and specialized books.

Assuming that the example of the initial state is as shown in FIG. 7, in this state, the corners on the second floor are hidden and cannot be seen. Here, by turning over the third floor, the second floor can be seen without changing the viewpoint. FIG. 8 shows a turned example. You can see the sales floor for books related to movies and music on the second floor. Of course, it does not mimic such a real building, but can be used for virtual libraries and virtual museums. It can also be used for three-dimensional topographic maps and the like. When used for a three-dimensional topographic map, for example, when a layer on the surface of a river is turned over, a layer at the bottom of the river appears, and it is possible to display living things and the like living there.

By providing the turning shape generation unit in this manner, a hidden place in the three-dimensional space can be seen without changing the viewpoint or the like, and the operation efficiency is improved.

(2) Embodiment 2 First, FIG. 9 is a block diagram showing a configuration according to Embodiment 2 of the present invention. The configuration according to the present embodiment will be described with reference to FIG.

In this embodiment, a perforated shape generation unit 211
Is provided, it is possible to see the data at the back without changing the viewpoint. Hereinafter, components different from those of the first embodiment will be described.

The perforated shape creating unit 211 creates a perforated shape based on a user operation input via the input means 1 and data in the data recording unit 3. The “drilled shape” here will be described later in detail.

The perforated shape creating section 211 further includes:
It comprises two components, a perforated shape calculation unit 212 and a perforated shape drawing unit 213.

The drilling shape calculation unit 212 determines a function having an appropriate drilling shape based on the designation of the input means 1. Specifically, it is a circle, an ellipse, a polygon, a free curve, or the like. In the free curve, for example, a hole may be formed by a curve that well covers a portion including many hidden icons.

The perforated shape drawing unit 213 draws a perforated shape in accordance with the function determined by the perforated shape calculation unit 212, and performs transmission processing of the perforated portion.

The display control unit 5 controls the display means 6 based on the data recorded in the data recording unit 3 and the perforated shape created by the perforated shape creating unit 211.

Next, a specific example will be described. The initial state is the same as in the first embodiment (FIG. 2). Further, an example will be described below in which the input means 1 is a mouse, but the present invention is not limited to this.

For example, it is assumed that the user wants to see the second layer from the top, that is, the layer of the map of Showa. The user moves the mouse pointer to the center of the point where he wants to make a hole.

Next, an instruction to start drilling is issued by a mouse click operation. This information is obtained by drilling shape calculation unit 2
12 are conveyed. When there is an instruction to start drilling, the drilling shape calculation unit 7 gradually transmits a large drilling shape to the drilling shape drawing unit 213 until an instruction to stop drilling comes.
In the following example, an example will be described in which a circle is used as the perforated shape. Therefore, a circle whose radius gradually increases is sent to the perforated shape drawing unit 213. The perforated shape drawing unit 213 performs permeation processing to permeate the perforated shape portion and draw an image of the following layer. FIG. 10 shows an example of a screen with holes. By drilling, the icon 81 of the Showa era high school baseball one layer below can be seen.

By providing the perforated shape generation unit 211 as described above, a hidden place in the three-dimensional space can be seen without changing the viewpoint and the like, and the operation efficiency is improved.

Further, in order to implement the information display device of the present invention by a computer, for example, the first embodiment described above is used.
In the configuration of (1), a computer program for generating the functions of the above-mentioned pocket shape creating unit 4 and display control unit 5 is created inside the computer, and the computer program is represented by a CD-ROM, a floppy disk, or a semiconductor memory. The recording medium is recorded on a recording medium, and the computer reads out the recording medium on which the program is recorded, thereby generating the functions of the turning-over shape creating unit 4 and the display control unit 5, and according to the first embodiment of the present invention. Can be constructed. The computer program may be, for example, in a form recorded on a recording device in a server, or in a form provided via a network. Furthermore, in this description, only the case of Embodiment 1 has been described, but the same applies to other embodiments.

[0043]

As described above, according to the present invention,
By providing the turning shape creating unit or the perforated shape creating unit, it is possible to three-dimensionally view the data on the far side with a simple operation without changing the viewpoint. Since hidden data can be viewed without changing the viewpoint, it is easy to grasp the positional relationship. In addition, since there is no need to perform an operation of adjusting the viewpoint so that the user can view the list, the operability is improved.
