FIG. 1 shows a schematic flowchart of the apparatus according to this embodiment. There is a selection screen S1 as a top menu, and an appearance selection screen S2, an introspection selection screen S4, and the like as lower menus. Hereinafter, each will be described with reference to the drawings.

1. Selection screen S1 FIG. 3 shows a selection screen. In the overall screen 1, an exterior screen 2 showing the entire view of the apartment, an interior 1 screen 3 showing the interior of a certain type of dwelling unit, and an interior view 2 screen 4 showing an interior view of another type of dwelling unit are displayed. Clicking any of the screens 1 to 3 advances to the next screen S2, S4, and so on. When the end button 5 is clicked, the program can be ended.

2. FIG. 4 shows an appearance selection screen. The main screen 11 displays a plan view of the apartment B, the parking lot P, and the road R,
Cameras 16c to 20c indicating the viewpoint positions are displayed. The main screen 11 also shows sub-screens 12 to 20 showing a display menu. Note that 12a to 15a indicate a movie screen, and when the sub-screens 12 to 15 are clicked, a movie screen, for example, a screen that gradually approaches an apartment from a distance is displayed. Clicking the return button 21 returns to the selection screen S1. When the end button 22 is clicked, the program ends.

The feature of this screen is the display of the cameras 16c to 20c. Immediately after the screen shown in FIG.
6c to 20c are not displayed. When the cursor is placed on any of the sub-screens 16 to 20, the corresponding camera is displayed. For example, when the cursor is placed on the elevation 16, four cameras 16c are displayed.
Other cameras are not displayed. Accordingly, the user can easily understand that the screen viewed from all directions can be viewed by clicking the elevation 16. In addition, appearance perspective 1 (1
When the cursor is placed on 7), the camera 17c is displayed. Thus, the user can easily understand that the screen viewed from the northwest can be viewed. Thus, the camera position is displayed by moving the cursor on the sub-screen.

FIG. 5 is an example of a screen displayed when the user clicks the elevation 16 in FIG. Along with the sub-screen 30 showing the elevation, the sub-screen 3 for clarifying the viewpoint position
5 is displayed. The elevation view of FIG. 5 is viewed from the south side, and therefore, the camera C is displayed on the south side of the plan view. When "North" 34 for displaying the elevation view on the north side is clicked, the elevation view on the north side is displayed and the camera C moves to the north side.

3. Introspection selection screen S4 FIG. 6 shows an introspection selection drawing S4. The floor plan 40 of the dwelling unit is displayed at the center of the screen, and sub-screens 41 to 48 for displaying each room are displayed. Camera C is located at the entrance.

When the sub-screens 52 to 56 below are clicked, the position of the camera C moves and a three-dimensional image viewed from the viewpoint after the movement is displayed. Since the camera position C is displayed on the screen 51 in synchronization with the display of the screen 50, it is easy to determine from which position the video is.

The sub screen 57 has a movie display 57a. When this is clicked, a sunshine simulation screen S6 showing the movement of the sunshine for one day is displayed. An example of the sunshine simulation screen S6 is shown in FIGS. These figures show the sunshine in the living room during the winter solstice from 8:00 am to 4:00 pm every hour. FIG. 8 (a) shows the situation at 8:00 AM, with no sunlight in the living room. FIG. 12B shows the situation at 9:00 AM, where the sun is shining through a part of the living room (the shaded area in the figure) from the right window. The figures after FIG. 9 show how the sunshine moves little by little. The state of PM5: 00 is not shown, but the sun does not enter the living room at this time. Note that these are examples of the case of the winter solstice, but it is needless to say that sunlight simulation at any time is not limited to this.

As described above, the sunlight simulation screen S6
According to the above, it is possible to easily and accurately know the state of sunshine of any dwelling unit. Since it is a three-dimensional image based on real computer graphics, the degree of appeal to the user is extremely high. Conventionally, in the sale of condominiums, it was possible to know the state of the room by the model room, but it was not possible to know what the environment such as the sunshine of the room actually occupy was. It was only possible to infer the approximate sunshine condition from the surrounding conditions and the general direction of the construction site. On the other hand, according to the sunlight simulation screen, it is possible to know the actual situation of the sunshine accurately and at a glance by designating an arbitrary time.
This simulation can provide more information to the condominium purchaser, which can be considered as a guide for purchase for the condominium purchaser and a sales promotion effect for the condominium provider.

The sunshine simulation screen S6 can provide a sunshine simulation of an arbitrary dwelling unit in accordance with the actual situation. Next, the method will be described with reference to the drawings.

In order to perform this simulation, as shown in FIG. 15, an apartment database M7a and a three-dimensional city map database M7b are required. The former is used to obtain information such as the height of the room, the size and orientation of the window when specifying a room with a certain dwelling unit, and the latter is to perform a sunshine simulation considering the surrounding situation Used. However, when performing a simulation in an ideal situation where there are no obstacles around, the three-dimensional city map database M7b is unnecessary. The apartment database M7a stores, for example, the location, size, shape, and height of apartments, the arrangement of dwelling units on each floor, the layout of each dwelling unit, the arrangement of walls, windows, furniture, and texture information for generating computer graphic screens. Including. The three-dimensional city map database M7b includes, for example, information such as the position, size, shape, and height of a building in a predetermined city.
For the contents of the three-dimensional city map database,
This is described in detail in Japanese Patent Application No. 9-335639.

FIG. 13 shows a flowchart of the simulation. First, a formula for sunlight is obtained (S10). Specifically, as shown in FIG. 14, the position (elevation angle and azimuth angle) of the sun corresponding to the season / time is obtained (S10a). Based on this result, a straight line group having the same elevation angle is defined (S10b). Next, based on the three-dimensional city database, the sunlight blocked by the target condominium is excluded (S10c). For example, as shown in FIG. 16A, sunlight blocked by building B is excluded. As shown in FIG. 16 (b), it is also considered that the state of shielding sunlight changes with the movement of the sun.

Next, a straight line passing through the window of the apartment room is extracted from the sunlight (S11). As shown in FIG. 17, a necessary straight line can be obtained by solving a simultaneous equation of the equation of the sun rays and the area W indicating the window. Actually, since the boundary portion becomes a problem, the straight lines L1 and L2 in FIG. 17 may be obtained.

Next, the intersection between the extracted straight line and the wall / floor is determined (S12). The intersections X1, of the above-mentioned straight lines L1 and L2 and the floor
Find X2.

Next, an area surrounded by a closed curve connecting these intersections is obtained and set as a sunshine area (S13).

Next, a texture expressing sunshine is attached to the sunshine area (S14).

Then, an image viewed from a predetermined viewpoint is formed (S15).

The aforementioned sunshine simulation image is obtained by repeating the processing of S11 to S15 at predetermined time intervals.

4. Examples of Other Simulations Another simulation provided to visitors in a model room of a condominium may involve a view. It is important for condominium buyers to see what view they can expect from home. Providing an actual view from the room you wish to purchase can be a great decision for condominium buyers. A view simulation image can be easily provided by using the system of FIG.

FIG. 18 shows a flowchart of the view simulation. First, a specific dwelling unit for which a simulation is desired and its room are designated (S20).

Next, the apartment database is searched to determine the number of floors (height of the viewpoint) and the direction of the window (the direction of the line of sight) of the designated apartment (S21).

Next, a three-dimensional city database is searched based on the obtained height of the viewpoint and the direction of the line of sight to extract a target building and terrain (S22).

Then, a screen viewed from the viewpoint is generated based on the extraction result (S23).

For example, a screen as shown in FIG. 19 is obtained. Of course, it is possible to display not only nearby buildings but also distant landscapes, mountain ranges, river flows, and the like.

By this simulation, the user can know in advance the view from the room desired to be purchased.
In addition, in the case of a condominium whose view is for sale, this simulation can directly appeal the selling point.

As other simulations, for example, a simulation of a commuting / commuting road in which the camera is moved to display an animation while moving a camera, and a simulation of guiding a nearby public facility or store are considered. Can be
