DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, in this embodiment, when a user intends to design a house (building), a user uses a communication line (such as a telephone line) from a personal computer 1 (see FIG. 2) prepared at home or the like. Connected to the Internet, server computer 2 of Internet connection company 2
A connection is made to the server computer 3a (host computer) of the building company 3 via a (S1).

Then, by reading predetermined data from the server computer 3a, the homepage of the building company 3 is displayed on the display device 5 of the personal computer 1 by using Internet browsing software (hereinafter, referred to as a browser). When a house is designed on a browser while receiving data (three-dimensional shape data) on rooms and parts from the PC (S2), three-dimensional shape data on the house is created on the personal computer 1.

Then, a virtual viewpoint is set on the browser for the three-dimensional shape data of the designed house, and the three-dimensional shape data is included in a predetermined angle range in front of the viewpoint while moving or stopping the viewpoint. By displaying each part of the house as a moving image or a still image on a browser based on the three-dimensional shape data, a so-called walk-through (displaying a moving image similar to actually walking around inside and outside the house) is performed. Then, on the browser, it is examined whether the layout of the designed house and the selection and arrangement of parts are appropriate on the browser (S
3).

After the design of the house and the examination by walk-through are completed, the user modifies the design of the house appropriately. Subsequently, when the user actually wants to build a house or at least wants a detailed design or the like by a designer in charge of the building company 3, the three-dimensional shape data on the designed house is transmitted to the building company 3 via the Internet. The data is transmitted to the server computer 3a (S4). Thus, the user can make a construction request or a design request to the construction company 3 online.

[0013] Thereafter, the building company 3 grasps the schematic configuration of the house the user wants to build based on the three-dimensional shape data sent from the user, and before the interview with the user, an accurate plan view of each floor. And the like, and if necessary, corrects the three-dimensional shape data of the house (S5). Prior to an interview with a sales representative or the like of the building company 3, the user browses the design drawings created by the building company 3 via the Internet, or based on the three-dimensional shape data corrected by the building company 3 as necessary. It is also possible to perform a walk-through again on the Internet (S6) and make a further correction request (S7) to the building company 3 by e-mail or the like.

Hereinafter, a procedure in which the user designs a house on the homepage HP of the building company 3 will be described. As shown in FIG. 2, a personal computer 1 used by a user includes a main unit 4 having a built-in storage unit (including a memory and a hard disk) and an operation unit and various software such as a browser, a CRT or a liquid crystal display. This is a normal configuration including a display device 5 including a display device, a mouse 6 and a keyboard 7 as input devices, and a printer 8.

FIG. 3 shows a server computer 3 of a building company 3 from a user's own personal computer 1 via the Internet.
a, and the homepage HP of the building company 3 is displayed on the display device 5. Unregistered users, that is,
A user who has not yet had a meeting with the construction company 3 regarding the construction and design of a house is available on this homepage H
When designing a house on P, "unregistered customer" in the item "house design" is designated by clicking the mouse 6 or the like. As a result, a signal indicating that “unregistered customer” has been selected is transmitted to server computer 3a, and necessary data is transmitted from server computer 3a to personal computer 1, whereby house design page P1 as shown in FIG. Is displayed.

The house design page P1 includes a tool selection area P1a and a drawing creation area P1b, and the floor of each floor of the house in the drawing creation area P1b using the tools selected by the user in the tool selection area P1a. You can create diagrams and so on. That is, at one end of the tool selection area P1a, selection buttons B1 to B5 for selecting various tools such as "room", "wall", "opening", "fittings", and "parts" are provided. The user selects desired tools by clicking desired selection buttons B1 to B5.

For example, when designing a layout, first, 1
When creating a floor plan, select room B by selecting button B1.
Is selected, a signal to the effect that "room" has been selected is sent to the server computer 3a. In response to this, predetermined data is sent from the server computer 3a to the personal computer 1, so that tools and the like are displayed as shown in FIG. In the selection area P1a, various room names such as "Japanese-style room" and "Western-style room" and the size of the room ("m" is omitted for units other than "tatami") are displayed. The user selects a desired room name and a desired room while appropriately scrolling using the vertical scroll bar T1 and the horizontal scroll bar T2.

For example, when the user selects "Western-style room" and "10 tatami mats" as a combination of the room name and the size by clicking the mouse 6, etc., as shown in FIG. "Western-style room" of "10 tatami" size becomes "Western-style room"
It is displayed as a rectangular graphic R1 accompanied by the display of the room name. G1 and G2 are grids that extend in the vertical and horizontal directions at predetermined intervals, respectively. The user places a mouse pointer on the upper left corner R1a of a rectangular “Western room” and drags the mouse (presses the button of the mouse 6). By moving the mouse pointer while moving the mouse pointer), the "Western-style room" can be positioned by matching the corner R1a with a desired position such as a desired intersection among the intersections of the grids G1 and G2.

In addition, the process of displaying the figure R1 in the drawing creation area P1b in accordance with the room selection operation in the tool selection area P1a and the drawing in the drawing creation area P1b in accordance with the dragging operation in the drawing creation area P1b. The process of moving R1 is performed based on a program (executable on a browser) sent from server computer 3a.
Side, or the tool selection area P1a
A signal corresponding to the selection operation on the screen or the drag operation on the drawing creation area P1b is transmitted from the personal computer 1 to the server computer 3.
a, and the graphic R1 may be displayed and moved on the personal computer 1 in accordance with the transmission of data and the like from the server computer 3a corresponding thereto. Hereinafter, the same applies to the case where rooms other than the “Western room” are sequentially provided.

Adjacent to the “Western room”, for example, “1”
When providing a “Japanese-style room” of “0 tatami” size, when the user selects “10 tatami” of “Japanese-style room” in the tool selection area P1a,
As shown in FIG. 7, a figure R2 representing a "Japanese-style room" having a size of "10 tatami mats" is displayed in the drawing creation area P1b. The user moves the mouse pointer to the upper left corner R
By performing a drag operation or the like in accordance with 2a, for example, the “Japanese-style room” can be positioned so as to be adjacent to the “Western-style room” in the lower part of FIG. 7.

Hereinafter, when various rooms on the first floor are designed in the same procedure, a plan view of the first floor as shown in FIG. 8, for example, is created. Each room has 2 in the drawing creation area P1b.
Although displayed as a dimensional plan view, it is actually created as three-dimensional shape data with a height dimension, and thus data of a room designed by the user constitutes three-dimensional shape data. Next, when a plan view of the second floor is created, when the “upper floor” button B6 provided at the lower end of the drawing creation area P1b is clicked, the drawing creation area P1b is blank as in FIG. A floor plan of the second floor can be created by the above procedure. FIG. 9 shows an example in which a “door” is provided at the corner of the second floor, and the description of the design of each room on the second floor thereafter is omitted.

If the "lower floor" button B7 is clicked during the preparation of the floor plan of the second floor, it is possible to return to the floor plan of the first floor of FIG. Further, when the "see lower floor" button B8 is clicked, the designed floor plan of the designed first floor is superimposed on the ground plan of the designed second floor by a virtual line or the like, although not shown, and the user can view the ground floor. You can check the positional relationship between the room on the second floor and the room on the second floor. If you click on the “Grid” button B9,
Display and non-display of the grids G1 and G2 can be switched alternately.

When the arrangement of the rooms on each floor is completed,
Walls can be modified and openings and fittings can be arranged. In the plan view of the first floor in FIG. 8, walls are automatically generated between adjacent rooms when designing a floor plan. In this case, each room is basically rectangular when viewed from above. For example, when it is desired to form a room having irregularities other than rectangular when viewed from above, although not shown, the selection button B2 is used to select “ wall"
By selecting, partial addition or deletion of a wall can be performed.

When an opening is formed between adjacent rooms, selecting "opening" with the selection button B3 displays various openings in the tool selection area P1a as shown in FIG. Here, "total height" means that the opening is formed over the entire height of the wall, and "height designation" means that the opening is formed by designating a height lower than the height of the wall. As a method of specifying the left and right widths of the opening, for example, a method of specifying two points on the wall corresponding to the left and right ends of the opening with the mouse 6 or the like in the drawing creation area P1b, or a method of selecting the left and right widths numerically Etc. FIG. 10 illustrates a state in which openings 10 are provided in the wall between the “broad edge” and the “Japanese room”, the wall between the “hall” and the “living room”, the wall between the “living room” and the “kitchen”, and the like. .

The arithmetic processing required to display the opening 10 on the drawing area P1b is the same as the processing for providing each room described above, which is a program sent from the server computer 3a (executable on a browser). May be performed on the personal computer 1 side using the tool selection area P1.
a in accordance with the operation of selecting the opening in FIG. 1A and the operation of designating the opening position in the drawing creation area P1b.
a, and after performing predetermined arithmetic processing on the server computer 3a side, the server computer 3a
Opening on the personal computer 1 based on the data sent to the
May be displayed. Hereinafter, the same applies to the processing procedure in the case of providing “fittings” and the like.

After the opening 10 is provided, when designing a fitting, if "fitting" is selected by the selection button B4,
As shown in FIG. 11, in the tool selection area P1a, a plurality of sizes of "entry doors", "indoor doors", "windows", and other "fittings" are displayed. Here, when a desired fitting is selected and a position where the fitting should be arranged in the drawing creation area P1b is specified, the fitting is displayed in the drawing creation area P1b. In the “entrance door” of FIG. 11, for example,
“Right 1.2” indicates that the hinge of the pivoting door is provided on the right side when viewed from the outdoor side, and the lateral width is 1.2 m. Reference numeral 11 in FIG. 11 denotes a door arranged by such a method, and 12 denotes a window. In addition, when various fittings such as doors and windows are selected from those having different shapes and designs, doors and the like having different shapes and designs are displayed in a list such as a front view and a perspective view in the tool selection area P1a. May be selected.

Next, when parts are arranged in each room,
When "parts" is selected by the selection button B5, as shown in FIG. 12, a plurality of different types such as "toilet bowl" and "bath tub" are displayed in the tool selection area P1a. Here, a desired part is selected, and the drawing creation area P1b is selected.
When the position at which the part is to be arranged is designated, the part can be arranged at that position. FIG. 12 shows a toilet,
Toilet 13, bathtub 14, washbasin 15 in the bathroom and washroom respectively
Are illustrated. When arranging the components, it is also possible to rotate the components at predetermined angular intervals, for example, in units of 90 ° in the drawing creation area P1b of FIG.

Incidentally, the components may be displayed in a list such as a front view or a perspective view in the tool selection area P1a and selected so that the shape, the color, the design and the like can be understood.
Parts such as the door 11, the window 12, and the toilet 13 are also displayed two-dimensionally in the drawing creation area P1b. However, in practice, the building company 3 uses the three-dimensional shape data having a height dimension in advance. Thus, the design data of the house and parts designed by the user are all created as three-dimensional shape data.

A "walk-through" button B10 located at the top of the house design page P1 is a button for performing a walk-through described below, and a "send" button B11 is used to send data on a house designed by the user to the building company 3. This is a button for requesting a home building.

When an "estimate" button B12 located at the bottom of the house design page P1 is clicked, an estimate of the total amount of money required for the designed house and used parts at that time is shown in, for example, part C. Will pop up. The user can enlarge or reduce the size of the house, add, delete, or change the parts while referring to the estimated amount. The estimated amount may be displayed not only as the total amount but also as necessary, for each unit or each unit. The house design data (three-dimensional shape data) displayed in the drawing creation area P1b is temporarily stored in a memory or the like in the main body 4 of the personal computer 1, but is clicked by a save button (not shown) or the like. It is also possible to write the house design data on a medium that can be stored even when the power is off, such as the hard disk of the main body 4.

Hereinafter, after the user designs the house as a whole,
A procedure for examining the configuration of each unit by walk-through will be described. When the walk-through button B10 is clicked on the house design page P1 in FIG. 12, as shown in FIG.
A walk-through page P2 including an image display area P2a and a viewpoint display area P2b is displayed.

First, the user performs initial setting of the viewpoint position in the viewpoint display area P2b. That is, the viewpoint display area P2
In b, a schematic plan view showing the first floor and the outdoors in the house designed on the house design page P1 is reduced and displayed, and the user sets the initial position of the viewpoint to any one of the first floor portions in the house or To set it outdoors, a desired position in the viewpoint display area P2b may be clicked in this state.

On the other hand, for example, the initial viewpoint is
If the position is set at any position of the floor portion, a schematic plan view of the second floor portion is reduced and displayed in the viewpoint display region P3b by clicking the "upper floor" button B13 beside the viewpoint display region P2b. In this state, an initial viewpoint can be set in the second floor (not shown). The viewpoint display area P2b
"Lower floor" button B1 with the second floor part displayed
When 4 is clicked, a schematic plan view of the first floor and the outside is displayed in the viewpoint display area P2b.

For example, in FIG. 13, it is assumed that an initial viewpoint V is set at a position outside the entrance 16 outdoors. Then, in order to determine the direction of the line of sight, the gazing point U is set at a position different from the viewpoint V by clicking the mouse 6 or the like. For example, when the point on the side of the entrance 16 is selected as the gazing point U, the direction of the line of sight is the direction of the arrow D from V to U, and the situation where the entrance 16 is viewed from outside is selected.

As described above, when the initial viewpoint V and the gazing point U are set, based on the position information of the V and U, an arrow D is normally moved from the viewpoint V by a calculation procedure incorporated in the browser. A CG image when looking at the direction is calculated based on the three-dimensional shape data of the house. That is, in FIG. 14, the inside of the quadrangular pyramid E having the initial viewpoint V as the vertex and the arrow D direction as the center line in the horizontal and vertical directions is defined as a virtual visual range, and the three-dimensional shape data F of the house is obtained.
A portion included in the quadrangular pyramid E in the two-dimensional projection plane G
The two-dimensional shape (including the color and the like) of the projected view projected on the computer 1 is obtained by the personal computer 1 in accordance with the above calculation procedure.

Based on the calculation result, an initial walk-through screen is displayed in the image display area P2a, for example, as shown in FIG. If the calculation procedure is not incorporated in the browser in advance, for example, a program including the above-described computation procedure can be downloaded from the homepage HP of the building company 3 and incorporated in the browser in a so-called plug-in format or the like.

In the subsequent walk-through, the viewpoint V is moved forward or backward by clicking the "forward" button B15 or the "backward" button B16 displayed on the walk-through experience page P2. Also, by clicking the "Rotate right" button B17, "Rotate left" button B18, "Rotate up" button B19 and "Rotate down" button B20, respectively, the line-of-sight directions indicated by arrow D are right, left, up, It is possible to rotate downward. The viewpoint V can be moved forward and backward using the mouse 6 and the like, and the line of sight can be rotated using the cursor keys on the keyboard 7 and the like.

In this case, rotating the line-of-sight direction D upward corresponds to an operation of looking up at an upper side (for example, a roof), and rotating the line-of-sight direction D downward corresponds to an operation of looking down at a foot. In that case, the height of the viewpoint V is constant even if the line of sight changes vertically and horizontally. The height of the viewpoint V can be set to be substantially equal to the actual height of the eyes of the user by, for example, inputting the height value of the user to the personal computer 1.

FIG. 16 shows the display contents of the walk-through page P2 when the viewpoint V is moved forward from the initial state of FIG. In this case, when the viewpoint V moves forward, as shown in FIG.
Since the portion included in the quadrangular pyramid E is reduced, the display device 5 displays a state closer to the entrance of the house as shown in FIG. Will be done.

When the viewpoint V is moved backward or the line of sight is rotated, the position of the vertex of the quadrangular pyramid E is similarly moved backward,
When the quadrangular pyramid E rotates around the viewpoint V as a vertex, a portion included in the quadrangular pyramid E in the three-dimensional shape data F changes, and the display content in the image display area P3a changes accordingly. I do.

By performing such operations continuously, as long as the viewpoint V continues to move, images showing the inside and outside of the house are displayed as moving images in the image display area P2a. When the movement of the viewpoint V is temporarily stopped, the scene located ahead of the viewpoint V at that time is displayed as a still image of the CG image in the image display area P2a. Since the viewpoint V and the line of sight at each point in time are displayed in the viewpoint display area P2b, the user can display any part of the house in the image display area P2a from the display contents of the viewpoint display area P2b. Can be confirmed.

As described above, the user can, for example, move or change the position of the viewpoint V and the direction of the line of sight outside the house, and change the position of the viewpoint V from the outdoor side of the house, that is, the outer walls, windows, fittings, and entrances. It can be considered whether or not the design such as is appropriate.

Subsequently, when examining the indoor side of the house by walk-through, for example, the viewpoint V may be moved to the indoor side through the entrance 16 by sequentially moving the viewpoint V. Click on the “viewpoint reset” button B21 arranged on the side of the display area P2b to change the viewpoint V
By resetting (and the gazing point U), the viewpoint V may be directly moved from the outdoor side to the indoor side, for example, to a desired position on the first floor portion.

FIG. 18 shows a case where, for example, the viewpoint V is moved into the living room 11 on the first floor. Like the outdoor side,
Based on the walk-through, the user examines whether or not each part on the indoor side, for example, the layout itself, the type of wallpaper, the arrangement of windows and fittings, and the type and arrangement of parts are appropriate.

When the user wants to modify the design of the house after the outdoor and indoor walk-throughs are completed, the user returns to the house design page P1 shown in FIG. Addition, deletion, correction, etc. of parts and parts can be performed. In addition, when the user wants to make a formal design request or a building request to the building company 3 for a house designed by himself / herself, the user clicks a send button B11, and FIG.
As shown in FIG. 9, the e-mail software Q starts.

Here, the user enters his / her name, address, comment (correspondence), etc., attaches the house data designed by him / her as an e-mail attachment,
It can be transmitted to the building company 3. In this case, in addition to the design data of the house, the user obtains data obtained by photographing the surrounding environment (adjacent houses and roads, etc.) of the planned construction site of the house with a so-called digital camera or a digital signal video camera. It is also possible to send it by attaching it to an e-mail.

The building company 3 receiving the design request or the building request from the user creates a detailed plan view of each floor based on the design data of the user (a plan view of the first floor is shown in FIG. 20). If necessary, the house designed by the user is corrected or the design is changed. In this case, the designer in charge of the building company 3 particularly asks whether the house designed by the user has a sufficient strength (for example, whether windows, openings, etc., are offset to a part of the house, one side, or the like). From a specialist's point of view, consider whether the arrangement of windows and ventilation fans is appropriate to ensure the ventilation of the house, and whether two or more rooms that require frequent traffic are not too far from each other. It is preferable to change the design as necessary.

When the user attaches data (digital photograph and video data) and the like relating to the surrounding environment of the planned construction site of the house, a three-dimensional image of the surrounding environment of the house is created based on these data and map data. Shape data may be created and combined with the three-dimensional shape data of the house.

Prior to actually meeting with a sales representative of the building company 3, the user uses the communication line from the personal computer 1 to communicate with the server computer 3 a of the building company 3 if necessary.
And the construction company 3 can browse design drawings (plan views of each floor and the like) created by the construction company 3 and perform a walk-through again based on the three-dimensional shape data appropriately modified by the construction company 3.

In this case, if the building company 3 has created three-dimensional shape data on the surrounding environment of the house, the walk-through can be performed in a state including the surrounding environment of the house. As described above, if a further correction is desired by browsing the design drawings or re-walking through, the building company 3 can be contacted by the e-mail software Q of FIG. It should be noted that, even after the user has interviewed a sales representative or the like of the building company 3 and has started a meeting or the like for designing an actual house, if necessary, the user can use the personal computer 1.
Needless to say, the user can browse and walk through the design drawings created by the building company 3 via the Internet, and make corrections on the design drawings on a browser.

In the above description, the case where the user independently designs a house using a browser has been described. Alternatively, a desired house model may be selected from a plurality of house models prepared by the building company 3. It is also possible to design the house while selecting it and modifying it appropriately according to one's own preference. In this case, the labor required for designing the house can be greatly reduced as compared with the case where the house is designed from a blank state. Further, in the above description, the user sends the data of the designed house to the building company 3 to make a design request or a building request. However, a user who does not plan to build a house can use a browser as a mere entertainment. It is also possible to design houses. In the above description, the house is designed on the browser using the Internet. However, for example, the house may be designed via a personal computer communication network hosted by the building company 3.
