When M7 is inserted, the screen shown in FIG. The image data constituting this screen is C
This is read from the D-ROM 7. The same applies to the following screens.

On the screen shown in FIG. 4A, first,
Items such as "1, proceed to basic information input", "2, create a floor plan", and "3, see the latest interior collection" are displayed, and any of these items is displayed active (inverted display, background color) (Display for distinguishing from other items such as display, or pointer display, hereinafter sometimes referred to as pointer)
It has become. Here, by operating the direction key CSW of the operation unit 8, the items to be displayed active are sequentially switched. When the button B is pressed in a state where “1, proceed to basic information input” is selected, the basic information input process is started, and a screen shown in FIG.

On this screen, "name", "age",
The user is prompted to enter a character or alphabet corresponding to each column of “telephone number”. At the bottom of the screen, alphabets, numbers, and the characters “cancel” are displayed. The customer operates the direction key CSW to move the pointer, and a predetermined button (for example,
When button A) is pressed, that character is entered. At this time, a guidance voice based on the voice data read from the CD-ROM 7, for example, "Please tell us first from your name."

When the input of the predetermined items is completed, the button B is pressed. When this button B is pressed, the input name, age, and telephone number data are stored in the RAM 3 and new image data is read out from the CD-ROM 7, and the TV 20 reads the image data shown in FIG. ) Is displayed. On this screen, input of the family structure is prompted. The customer moves the pointer to the “male” and “female” portions in the “adult”, “elderly”, and “child” fields and presses a predetermined button (for example, button A). As a result, an illustration icon indicating the corresponding family is displayed in the corresponding column. In the example shown in the figure, one adult and one male adult, one elderly male and one female, one child child, and two females are input. In addition, a guidance message such as "Please tell us your family structure" is pronounced along with the screen display.

When the input of the family structure is completed, the button B is pressed in the same manner as described above. As a result, data on the family structure is stored in the RAM 3 and
The next screen data is read out from the CD-ROM 7, and FIG.
It is displayed as shown in FIG.

On the screen shown in this figure, the user is prompted to enter a budget. Then, a guidance voice such as "Please give us an estimate of the budget of the building you are planning." On the screen, icons indicating a bundle of 10 million yen, 5 million yen, and 1 million yen are displayed. When the pointer is moved to a desired icon and the switch A is pressed, the same icon is displayed in a corresponding display field. Will be displayed. In the illustrated example, two icons of 10 million yen, one icon of 5 million yen, and two icons of 1 million yen are displayed in the respective display columns, and the "Budget" column in the center of the screen , The total amount of 27 million yen is displayed by a numeral. In this case, since the input of the budget is performed by selecting the icon instead of the number, the operation can be performed without feeling uncomfortable.

The calculation of the total amount is performed by the CPU 2 detecting the operation of the operation unit 8 and the result is sent to the image processing unit 5, whereby the numerical value as shown in FIG. 5A is displayed. . When the input on this screen is completed and the button B is pressed, the amount of "budget" is stored in the RAM 3 and the image data of the next screen is read from the CD-ROM 7, as shown in FIG. Will be displayed. Here, the display of each column of “budget”, “name”, “age”, “telephone number”, and “family composition” is performed based on the data stored in the RAM 3. When this screen is displayed, the sound "Please confirm. If you like, please click the confirmation button. Return to the previous screen with button B."

Each time the button B is pressed, it is possible to return to the previous screen sequentially.
The user can return to the corresponding screen and make corrections. on the other hand,
If there is no error in the displayed contents, move the pointer to the "confirmation" part displayed in the upper right part of the screen and press the A button. As a result, the image data of the next screen is read from the CD-ROM 7, and the screen shown in FIG. 5C is displayed.
In this screen, a woodgrain-like door giving a Japanese image is displayed on the right side of the screen, and an off-white door giving a western image is displayed on the left side. Then, a voice is issued saying "Please tell us your lifestyle image to propose the best interior coordination. Which of the photos you see is close to your favorite life scene?" The customer moves the pointer to one of them and presses button A. This selection information
Stored in M3.

Next, as shown in FIG. 6 (a), a photograph of a single color modern tableware and a classic tableware with a pattern are displayed. In this case, a sound saying "Which image is closer to your preference for tableware design?" When one of them is selected in the same manner as described above, the selection information is stored in the RAM 3 and then, as shown in FIG.
The display shown in (b) is made.

On this screen, four chairs having different design styles are displayed. Then, a voice saying, "If you choose a chair design, which type of this photo?" Is issued, and the selection is prompted. When the customer selects one, the selection information is stored in the RAM 3. Here, the selection data in FIG. 5C, FIG. 6A, and FIG. 6B becomes information indicating the preference of the customer. In particular, since rooms, furniture, tableware, and the like are often manufactured as a series based on a unified image, such preference information is important information in selecting a room design and furniture described later.

Floor plan creation mode (a) Creation processing When the furniture selection shown in FIG. 6 (b) is completed, FIG. 6 (c)
The display shown in is displayed. In addition, "If the floor plan of the building you are planning is decided? If you are considering, select" NO "and enter the total floor area. We propose a sample layout. Is emitted.

When the customer selects "NO",
The floor area can be input, and the numerical value displayed at the bottom of the screen is selected by the pointer to input the floor area. In the illustrated example, “250Hm” is displayed. In this case, a room configuration such as 2DK or 4LDK may be input instead of numerical input. And
When this input is made, the sample layout is displayed (in a modified example described later).

On the other hand, when "OK" is selected on the screen shown in FIG. 6C, a grid as shown in FIG. This grid has a cross shape as shown in detail in FIG. 8, and is arranged in a matrix at regular intervals. The range surrounded by the four grids (see C in the figure) is hereinafter referred to as a cell. In the case of this embodiment, the size of each cell corresponds to half a tatami mat.

When the button A is pressed while the grid shown in FIG. 7 is displayed, the room pallet shown in FIG. 9B is displayed. When the button A is pressed again, the wall pallet shown in FIG. 9C is displayed. When the button A is pressed again, the floor pallet shown in FIG. 9A is displayed. And
When button A is pressed again in this state, only the grid is displayed. Thus, every time the button A is pressed, the switching is performed in the order of the room pallet → the wall pallet → the floor pallet → the grid only. The room pallet is a pallet for specifying the type of room when the floor plan is performed, the wall pallet is a pallet for specifying the type of wall, and the floor pallet is a pallet for specifying the floor on which the floor plan is designed.

Here, when each pallet is selected,
The corresponding object descends from the upper part of the screen and is displayed at a predetermined position. As an example, FIG. 10B shows the display position of the floor pallet, but other pallets are also displayed at substantially the same position. FIG. 10B shows a state in which a floor pallet is displayed on a floor plan described later.

Next, a procedure for creating a floor plan will be described. First, display the floor palette and specify the floor on which the floor plan is created. Here, FIG. 10A shows a screen when “3F” is selected on the floor pallet, and “Layout P” is displayed at the upper left of the screen as shown.
“lan” is displayed, and “Floor” is displayed in the lower right of the screen.
"3" is displayed. The pointer displayed at the center of FIG. 10A is a shape in which a human hand holds a writing instrument. The shape of the pointer may be different depending on each mode (floor surface, wall surface, cancellation, etc.).

When the cell indicated by the pointer is selected after designating the floor, the cell is painted in units of cells as shown in FIG. In this case, the selection of the cell is performed by, for example, pressing the button A, and the filling is performed by a predetermined pattern indicating the temporary coating. Note that the temporary coating can be performed first, and then the floor can be designated.
At this time, the pointer moves on the cell when the direction key CSW of the operation unit 8 is operated.

Next, a room palette (see FIG. 9B) is displayed, and any room name is selected. The selection is made by, for example, pressing the button A after moving the pointer to a desired room name. As a result, the portion where the temporary coating has been performed is recognized as the selected room name, and the display is switched to the display according to the room. As shown in FIG. 9B, the room names on the room pallet include a living room, a dining room, a kitchen, a Japanese-style room, a Western-style room, a washroom, a toilet, a corridor, a bedroom study, and a bath. Colors and patterns are displayed as different buttons.

As described above, the position and size of the living room, corridor, stairs, entrance, toilet, etc. are set by temporary coating, and then the room palette is displayed.
When a desired room name is selected, the temporarily painted portion is displayed as the room. That is, the name of the room is displayed, and the display is made in a pattern or color corresponding to the room. Here, FIG. 12 shows a display example when some room names are selected. In the state shown in this figure, temporary coating is performed on the left end portion of the floor plan. In the state where the above-described room name setting process has been performed, each room is entirely surrounded by a wall, and the wall is displayed by a black line.

Next, a case where a room set once is canceled will be described. In this case, operate the direction key CSW to specify the room to be canceled with the pointer,
Display the room palette and select "Cancel". As a result, the room returns to the temporary coating state, and again,
One of the room names can be set. When the room designated by the pointer is in the temporary paint state, if "cancel" is selected on the room palette, the entire room is erased, and a grid display is displayed. When the button A is pressed in the temporary coating state, only the cell indicated by the pointer is deleted.

After setting the name of the room, doors, brans, glass doors, and openings (portions without walls) are set for windows and surrounding walls of the room. This setting is performed by displaying a wall pallet and selecting windows, doors, and the like. That is, the wall pallet shown in FIG. 9C is displayed, and one of “window”, “door”, “bran”, “wall”, “glass door”, and “take a wall” is selected. When one of the modes is selected, the pointer moves on a line connecting the grids, that is,
It moves on the wall (see the broken line in FIG. 11). At this time, the selected mode, for example, the character (or button) of “window” is displayed at the lower left of the screen (not shown).

When the direction key CSW is operated, the pointer moves while indicating the line segment. When the desired position is reached, the button A is pressed. This replaces the wall in that portion with the selected aspect. That is,
If a window is selected, it is replaced with a window, and the window is displayed (for example, the color of the line segment is changed to light blue). In order to cancel the set window or the like, “wall” in the wall pallet may be selected, and the corresponding line segment may be returned to the wall.

By repeating the above operations, a floor plan is created. Floor plans can be created for other floors by the same operation. Here, FIG.
It is a display example at the time of setting the floor plan of the second floor part. When "floor" on the wall pallet is selected, the screen returns to the room name setting screen. As described above, when the floor plan is completed, the floor pallet is displayed, and “completed” is selected. As a result, the data necessary for the configuration of the floor plan is
It is stored in M3. That is, data indicating the position, shape (area), name, and state of the wall of the room are stored.
Here, FIGS. 15 and 16 are flowcharts showing the above processing contents.

(B) Display Processing (Basic Display Processing) Next, the display processing of each room in the above-described creation processing will be described. FIG. 17 is a conceptual diagram showing codes corresponding to cells when a room name is specified. A portion surrounded by a thin solid line in the drawing indicates a storage area (set in the RAM 3) corresponding to a cell, and a thick solid line indicates a frame of a room. The numerical value in the room frame is a code indicating the room name. The code shown in FIG. 17 is represented by a one-digit numerical value for simplification. In this example, “1” indicates a kitchen, “2” indicates a dining room, and “3” indicates a corridor.

As described above, when the room name is specified, the code is written in the corresponding storage area. Next, FIG. 18 shows a material illustration data storage unit IM that stores illustrations (patterns and colors) of the floor surface of each room in units of cells, and is set in the CD-ROM 7. The material illustration data storage unit IM stores, for example, a corridor illustration P1, P2, a kitchen illustration P3, a dining illustration P4, and the like, and a wall illustration P6.
P7 and the like are also stored.

In this case, in the illustration P1 of the corridor, the grain is in the horizontal direction, and in P2, the grain is in the vertical direction.
Further, a wall illustration P6 indicates a vertical wall, and P7 indicates a horizontal wall.

When creating the floor plan image data, for example, the data of the illustration P4 is assigned to each cell constituting the dining room, and the data of the illustration P3 is assigned to each cell constituting the kitchen. In this way, a display as shown in FIG. 12 is made.

When there is directionality like the illustrations P1 and P2 of the corridor, the shape of the room is divided into a set of rectangles, and then each illustration data is assigned. How to divide
First, the largest rectangle inscribed in the room is selected. Then
Select the largest inscribed rectangle for the rest of the room. Thereafter, rectangles are selected for the remaining portions in the same manner, and the process ends when one rectangle is finally formed. Therefore, if the shape of each room is a rectangle or a square, illustration data is assigned to the shape without being divided.

After the division as described above, illustration data is allocated according to the shape of each rectangle. For example, in the case of a corridor, a plate whose illustration data is along a rectangular longitudinal direction is selected. As an example, since the corridor portion ("3" portion) shown in FIG. 17 is a rectangle that is long in the horizontal direction in the first place, data having a grid in this direction, that is, illustration data P1 shown in FIG. 18 is selected. This data is assigned to each cell.

The illustration data is assigned to the stairs as follows. First, the illustration data P10, P11, P12, and P13 shown in FIG. 18 are the illustration data of the curved portion of the stairs, and by using these illustration data appropriately, any curved portion can be drawn. Further, the illustration data P14 and P15 are illustration data of a straight portion of the stairs, respectively, and when the straight portion continues, these are alternately combined.

Here, FIG. 19 is an example of drawing of a step portion. When drawing a stair, the cell adjacent to the cell designated as the stair (the cell with a star in the figure)
Find out what kind of. When the adjacent cell is a corridor, the illustration data P14 or P15 is arranged so that the cell becomes the entrance of the stairs. Then, cells corresponding to the way of bending are selected from the cells P10 to P13 and arranged in the cells of the bent portion. In this way, the stairs are drawn as shown in FIG.

For a Japanese-style room, the following processing is performed based on the size of the divided rectangular shape. First,
The illustration of the tatami mat shown in FIG. 20 is stored in the illustration data storage unit IM in advance. Here, FIG. 20A shows illustration data for one cell of half-tatami, and FIG.
It is an illustration for a cell. Similarly, FIG.
(D), (e), (f), and (g) are illustration data of 3 tatami mats, 4 tatami mats, 6 tatami mats, and 8 tatami mats, respectively.

When drawing a Japanese-style room, the largest one that enters the Japanese-style room is selected from the patterns shown in FIG. Next, the largest pattern that fits in the remaining space is selected, and the pattern is sequentially selected by the same method.

20B, 20D, and 20F store illustration data in both vertical and horizontal directions, and correspond to the direction of the remaining space. You may make it select a thing. Further, in general, a Japanese-style room is a rectangle such as 6 tatami mats or 8 tatami mats, and therefore, in many cases, the illustration data shown in FIG. 20 is directly assigned to the shape of the Japanese-style room itself.

Next, the drawing of the wall is performed according to the orientation (vertical or horizontal) of the illustration patterns P6 and P6 shown in FIG.
7 is selected and assigned. This is the same processing content as in the case of the corridor described above.

(Additional Display Processing) Now, FIG.
FIG. 2 is an enlarged view of the floor plan shown in FIG. 2, but in this embodiment, the following special processing is performed on the display of the bath, the toilet, and the bedroom study. That is, for three types of rooms, a bath, a toilet, and a bedroom study, a bath tub a1, a toilet a2, and a bed a3 are drawn if the size is equal to or larger than a predetermined value. More specifically, for the bath, if the room is larger than 2 × 2 cells, the bathtub a
1 is displayed on the bus (see FIG. 14). For the toilet, if the size is 1 × 2 cells or more, an illustration of the toilet a2 is displayed. For the bedroom study, if the size is 2 × 3 cells or more, the bed a is displayed.
3 is displayed.

The illustration data of these bathtubs, toilets, and beds are stored in the illustration data storage unit IM in advance. If the bath, toilet, and bedroom study have the above-described sizes, the illustration data storage is performed. The information is read from the unit IM and is superimposed and displayed in the cell of the room. in this case,
The display direction of the bathtub, toilet bowl, and bed can be either vertical or horizontal.
One direction is stored, and one is selected according to the shape of the cell to be displayed. The processing may be simplified so that the images are always displayed in the same direction.

When the above processing is completed, three-dimensional display is performed based on the input floor plan information. In this process, predetermined information is calculated for each cell, and a stereoscopic display is performed based on the calculated information. here,
The calculation of the predetermined information will be described.

FIG. 21 shows information of one cell. As shown, floor information D1 indicating a floor, a living room, a kitchen, etc., position information D2 indicating coordinates of a cell,
It has upper wall information D3 indicating the type of the upper wall and left wall information D4 indicating the type of the left wall.

FIG. 22 is a simplified view of a cell in which a room name is set. In this figure, information D1 to D4 in each of the cells is as follows. (Cell) Floor information D1: Dining location information D2: (3, 3) Top wall information D3: Wall Left wall information D4: Door (Cell) Floor information D1: Kitchen Location information D2: (3, 2) Top wall Information D3: No wall Left wall information D4: Wall (cell) Floor surface information D1: Living location information D2: (2, 3) Top wall information D3: No wall Left wall information D4: No wall

As described above, four pieces of information are obtained for each cell. In this case, the set floor plan can be completely restored by combining information of all the cells.

Next, the three-dimensionalization will be described by taking the above-mentioned (cell) as an example. As shown in FIG. 23, in order to make a (cell) three-dimensional, information on four surfaces (walls) that stand vertically from four sides of the (cell) is required. By the way, the coordinates of the eight vertices of the three-dimensional object shown in FIG.
2 and the size of the cell itself.
A constant value is previously determined for the coordinates (height). Therefore, it is understood that the coordinates of all vertices can be obtained under the above conditions. The height may be determined by key input, external input, or the like.

Next, the color of the inner surface of each three-dimensional surface is the color of the floor information, that is, the color of the dining room in this case. Then, when a surface standing at the boundary with (cell) is defined as a − surface, and a surface standing at the boundary with (cell) is defined as a − surface,
The outer surface of the surface is the color of the (cell) floor information, that is, the kitchen color in this case, and the outer surface of the surface is the color of the (cell) floor information, that is, the living color in this case. However, windows, "doors", "bran",
When "glass door", "take a wall", etc. are set, the color and shape of the wall are set according to the setting status.

When the above information is obtained for all the cells, information for making the floor plan three-dimensional is provided. And
By supplying this information to the modeling means,
A solid is assembled in the virtual space. The modeling means is
It is provided in the image processing unit 5 shown in FIG. Note that the modeling itself may use a well-known method, and thus the description is omitted.

Next, based on the three-dimensional layout in the virtual space by the modeling means, two-dimensional information when viewed from a predetermined viewpoint is calculated by the rendering means, and the result is displayed on the television 20. The rendering means is provided in the image processing unit 5 like the modeling means. Also, a well-known technique may be used for this rendering means, and a description thereof will be omitted.

Here, FIG. 24 is a display example of the processing result by the rendering means, and is a three-dimensional view of the first floor portion.
This figure is a three-dimensional view when viewed from the initial viewpoint. Then, to move the viewpoint, the direction key CSW of the operation unit 8 is operated. As a result, the operation information of the direction key is detected by the CPU 2, and the viewpoint information corresponding to the operation information is detected by the CPU 2.
2 to the image processing unit 5. As a result, the rendering means calculates the two-dimensional information corresponding to the new viewpoint and displays it on the television 20. Therefore, the customer can view the three-dimensional view of the floor plan from any viewpoint. The above display is performed in the same manner on the second and third floors.

In this case, since information is extracted and three-dimensional modeling is performed on a cell-by-cell basis, the processing is simplified and the overall processing speed becomes extremely high.

Product determination processing Next, a product for realizing a floor plan, that is, a floor material,
The process proceeds to a process for specifically determining products such as doors and windows for composing a room and products such as chairs and tables.

FIG. 25 is a diagram showing an outline of this processing. 50 shown in the figure is a budget distribution information table,
It is stored on the CD-ROM 7. The information table 50 for budget distribution includes a layout of a water area, a public zone,
When divided into private zones and the like, this is a table storing the cost distribution of each zone with respect to the entire cost, and is created based on statistical data. here,
There are rooms such as baths and toilets around the water, rooms such as living and dining in the public zone, and bedrooms in the private zone.

In processing step SPa1, the distribution amount of each zone is calculated from the budget distribution information table 50 and the approximate budget input on the screen of FIG. 5 (a). The budget amount of each zone in the table 51 is automatically determined. The room-specific information table 51 is a RAM3
(See FIG. 2). When writing the distribution amount, if there is an instruction from the customer regarding the budget distribution, the correction is manually made.

Next, the process proceeds to step SPa2, and FIG.
The lifestyle (preference information) input on the screen (c) and the size of each room obtained from the floor plan are automatically written in predetermined columns of the room-specific information table 51. Further, a budget for each room is calculated and written based on the style and the size of each room. In this case, the calculation of the budget for each room is performed based on a table or statistical formula obtained from statistical data. In the example shown in FIG. 25, 4 million yen is allocated to the zone around water, of which 2
100,000 yen and 500,000 yen are allocated to toilets.

Next, a process for setting a style for each room will be described. Here, 52 shown in FIG.
-1, 52-2, 52-3,... Are room-by-room style tables in which styles for each room are recorded. These room style tables 52-1, 52-
In 2,52-3,..., The horizontal axis indicates the size of the room, and the vertical axis indicates the price (grade). Further, the room-specific style table 52-1 shown in the figure is a table in which a style about the living room is set. For example, in the case of 12 tatami mats and grade 2, there are two “Western style 3” and “Western style 4”. It can be seen that the style can be selected, and when it is grade 3 with the same size, “Western style 2”, “Western style 3” and “Japanese style” can be selected. Other room style tables are similarly configured.

Next, 53-1 and 53-2 shown in FIG.
53-3 is a product table, which records a group of products according to room, size, style and price (grade). For example, the product table 53-1 shown in FIG.
Is a 12 tatami mat living room with a price (grade) of 80-
1M shows a group of products when the style is Western style 3. The product groups are classified into frontage members (doors, windows, etc.), interiors (ceiling materials, wall materials, flooring materials, etc.), lighting, furniture, etc., and for each category, product candidate 1, product candidate 2. Indicate the candidate 2).
For each product, a product number is stored.

Now, as can be seen from the contents of each table described above, a style according to the budget and the layout is selected using the room-specific information table and the room-specific style table.
By searching for a product table corresponding to this, it is possible to determine products for constituting the room, furniture such as chairs and tables.

Next, operations up to product selection will be described. This operation is performed in a predetermined room order such as, for example, entrance, living room, dining room.... now,
Assuming that a product selection operation is performed for the living room, first, as shown in FIG. 28, living room photographic data corresponding to the style shown in the room-specific style table is read. In this case, if the area is 12 tatami mats and the grade is 2, the styles of Western style 3 and Western style 4 can be selected as shown in the room style table 52-1. In this embodiment, for example, Western style 3 is automatically selected. Then, the photograph data (prerecorded in the CD-ROM 7) suitable for the style is read out and displayed on the television 20. FIG. 28 is an example in which photo data of a living room 3 of Western style is displayed. Then, the room name “living room” is displayed at the top of the screen, and the photo data of the style “Western style 3” is displayed. In addition, buttons of “enter” and “change” are displayed at the bottom of the screen. That is, the pointer is moved using the direction key CSW,
When "change" is selected, the photograph data of the living room 4 of the Western style is displayed. Here, if there is a candidate style,
Every time "change" is selected, the photo data corresponding to the next candidate is read and displayed. On the other hand, when "decision" is selected, the style is decided and the display shifts to the display shown in FIG. In this case, the display in FIG. 29 is a photo of the living room (not shown), and “Change proposal” is displayed at the bottom of the screen.
Buttons such as "Product 1", "Product 2", and "To the next room" are displayed. Here, if "change proposal" is selected, the display returns to the display shown in FIG. “Product 1” and “Product 2” correspond to furniture arranged in the living room. And, for example, "product 1" corresponds to the living board,
If “Product 1” is selected while “Product 2” corresponds to the sofa, the display shown in FIG. 30 is displayed. In this display, the product name “living board” and style “modern” are displayed at the top of the screen, and the product number and price are displayed at the bottom of the screen. In the center of the screen, a picture (not shown) of the product is displayed. Also, at the bottom right of the screen,
The buttons of “enter” and “change” are displayed. When “enter” is selected, the displayed product is determined and returns to the display of FIG. 29. When “change” is selected, the next candidate is displayed. The living board is displayed. In this case, the selection of each product is performed according to the product table 53-1 shown in FIG. 27, and the photograph data corresponding to the product number read from this table is displayed.

As described above, the style of the room, the members constituting the room, the furniture placed in the room, and the like are determined. By performing this operation for each room, materials and furniture of each room corresponding to the designed floor plan are determined. Note that there may be no furniture set in a corridor or the like.
9, the display of FIG. 30 is not performed, and only the entire display of FIG. 28 is performed.

When the above-mentioned operation is completed, a guidance voice is given, "Thank you. Then, let's introduce the customer's comprehensive proposal in the order of rooms."
Photographs of rooms and furniture decided so far will be shown. At this time, the video player 21 (see FIG. 1)
Shall record the contents of the screening. Then, when the screening ends, the display shown in FIG. 31 is performed. The recorded video tape 22 is given to the customer.

Recording / Transmission Mode The display in FIG. 31 shows three modes: “communication”, “save”, and “do not save”.
One button is displayed, and a window displaying the proposal code is displayed. Here, if "not save" is selected, the floor plan data and the product data recorded in the RAM 3 until now are deleted.

Here, a serial number is automatically assigned to the proposal code. When "Save" is selected, the proposal code is stored in an external medium (not shown) such as a floppy disk or EP-ROM. The data in the RAM 3 is recorded together with the proposal code. When communication is selected, the data in the RAM 3 and the identification code are transmitted via the transmission unit 11 in FIG.
Is transferred to the workstation 30 shown in FIG. The workstation 30 creates a catalog as shown in FIGS. 32 and 33 based on the transferred data.

FIG. 32 is a cover of the catalog, and FIG. 33 is a part of the catalog. The cover shown in FIG. 32 has a simple comment about each room on the left side, and an image photograph showing the style of each room selected on the screen shown in FIG. . Each room in the floor plan is numbered, and the images and comments are also numbered.

The catalog shown in FIG. 33 is an example of a living room, and a similar catalog is created with one page per room in principle. The part a shown in FIG.
It is a floor plan, and a portion corresponding to the living room is displayed in different colors. In part b, an image photograph of the furniture selected on the screens shown in FIGS. 29 and 30 is displayed.
Shows a variation of the furniture.
Part d is optional furniture.

On the other hand, the left part e (column) on the left side of the catalog displays images and explanations of members such as ceiling materials, floor materials, doors, and lights based on the data of the product table 53-1. These are members selected based on the data of the product table 53-1. As described above, the product table 53-1 stores the budget, the area, and the
Is a table selected according to the room style determined on the screen of FIG.

Next, a part f (row) and a part g (row) indicate the same members as the part e, but are displayed as variations. These variations have been selected based on data stored in the workstation 30.

The above-described catalog creation is performed as follows. That is, the workstation 30 reads out the image data and character data stored in the character image database 31 in accordance with the data transferred from the multimedia player 1, and arranges these data as shown in FIGS. Is output to the color printer 32.

The created catalog is used for discussion with the customer, and the plan is further reduced. At this time, various corrections are often issued,
The correction data is input at the workstation 30 or the multimedia player 1, and the finally determined styles and members of each room are selected.

Next, in the workstation 40, the finalized style and member data of each room is received from the workstation 30, and based on the received data, the entire image catalog shown in FIG. 34 is created. . That is, the floor plan is received from the workstation 30, data indicating the budget, style, members, etc. of each room is received. Based on the data, the character image database 41 is accessed, and the data and characters of the corresponding image photograph are read. Then, the floor plan is arranged at the center, and the surroundings are automatically arranged so that the photographs of the respective rooms surround the room. For this automatic arrangement, the following method is used.

First, an area other than the floor plan, that is, an empty area is detected, and a pattern frame for displaying an image photograph is set here. The detection of the empty area is performed for the upper, lower, left and right areas surrounding the floor plan. Next, after the empty area is detected, it is determined whether or not the image of the image photograph can be stored in each empty area. In this determination, since the image size of the image photograph is known, each image is compared with the empty area, and which image is stored in which empty area is set. However, the image of each room is preferentially arranged so as to be close to the corresponding layout position. Then, as described above, the midpoint of the image arranged in the empty area and the designated point (see the black circle in the figure) preset in each room of the floor plan are connected by a solid line. In this process, when the center coordinates of the designated point are (X1, Y1) and the center coordinates of the corresponding image are (X2, Y2), the coordinates (X1, Y2)
And a line segment L1 from the coordinate (X2, Y2) to the coordinate (X1, Y2).
This is performed by drawing a line segment L2 from 1) to the coordinates (X1, Y2). Similar processing is performed between each designated point and the corresponding image. After the line segment is drawn, the following points are evaluated. (i) Does it overlap another image? (ii) Does it overlap another line segment? (iii) How far is it from other line segments? Next, the line segment having the lowest evaluation point is appropriately moved.
For example, the evaluation points when various movements are made in the vertical and horizontal directions are calculated, and a line segment having the highest score is detected and replaced with the detected line segment. After this replacement, the line segment having the lowest evaluation point is detected again. Here, the “line segment with the lowest evaluation score” is generally different from the one selected first. In other words, the line segment having the lowest evaluation point first has a high possibility that the evaluation point will be improved by performing the above-described processing, and the target of the processing here is, in general,
Another line segment.

As described above, the process of increasing the value of the line segment having the lowest evaluation point is repeated, and the overall evaluation point gradually increases. Then, when such processing is performed a predetermined number of times (for example, 30 times), a line segment that does not overlap with another image or line segment can be drawn. Note that such automatic processing may require correction,
In such a case, a manual correction process is performed.

After completion of the above-described line drawing process, the image data of each photograph, the floor plan, and the print data of the line segments are supplied to the color printer 42. As a result, the color printer 42 outputs the entire image catalog shown in FIG. As described above, the creation of the entire image catalog, which has been conventionally performed manually such as cutting and pasting, can be automatically performed based on the data transferred from the workstation 30.

C: Modified Example The processing of the workstation 40 may be performed by the workstation 30 to simplify the configuration.

In the above embodiment, the floor plan is written from the beginning, but if the plan has not been decided, several floor plan patterns are prepared in advance.
This may be corrected.

When "view latest collection of interiors" is selected as shown in FIG. 4A, interior photographs recorded in advance on the CD-ROM 7 are sequentially displayed.

§2. Second Embodiment According to the above-described first embodiment, there is an advantage that a three-dimensional view corresponding to a floor plan can be displayed quickly and easily, and an image of a floor plan desired by a customer can be promptly proposed. However, products (floor materials, wall materials, doors, furniture, etc.)
However, since the proposal is made using a single product photograph or a photograph in a model room, there is a problem that it is difficult to grasp the layout that the customer has imagined. In view of this, the second embodiment aims at proposing a product in relation to the floor plan imagined by the customer.

A: Configuration of the Embodiment The configuration of the second embodiment is basically the same as that of the first embodiment. However, in the first embodiment, the floor information D1 of each cell indicates the room name as the floor type, whereas in the present embodiment, the floor information D1 is information indicating the floor material type. Similarly, as for the wall, the first embodiment has shown the aspect of the wall such as the wall, the no wall, and the door as the type of the wall, whereas in the present embodiment, the type of the wall member, that is, Indicates the type and type of door. For this reason, the material illustration data storage unit IM stores, for example, FIG.
As shown in FIG. 5, a plurality of illustration data corresponding to the materials of the wall material and the floor material are stored, and the illustration data of each type is also stored for the door. And
The information held by one cell is, for example, in the case of FIG.
It is configured as follows.

(Cell) Floor information D1: Floor material B Position information D2: (3, 3) Upper wall information D3: Wall material A Left wall information D4: Door A (cell) Floor information D1: Floor material C position Information D2: (3, 2) Upper wall information D3: No wall Left wall information D4: Wall material B (cell) Floor surface information D1: Floor material D Position information D2: (2, 3) Upper wall information D3: No wall Left wall information D4: No wall

The material illustration data storage section IM stores illustration information of three-dimensional furniture.
The illustration information in this case is information indicating the display mode of each surface with the shape data necessary for the modeling process, and in order to cope with various types of furniture placement, a plurality of illustration information having different directions for one piece of furniture. Are stored as a set. And about each furniture, a display position and a display direction are controlled by furniture display information. Here, an example of furniture display information is shown. (Cupboard A) Position information D1: (3, 4) Orientation information D2: (1) (System living B) Position information D1: (1, 3) Orientation information D2: (2) In this case, the position information D1 is used. The cell where the furniture is placed is determined. In addition, the illustration information of the direction corresponding to the value of the direction information D2 is read out and arranged at a position corresponding to the direction. For example, in the case of a cupboard or a closet, they are arranged along a wall according to the direction.

B: Operation of Embodiment When modeling and rendering are performed in the same manner as in the first embodiment based on the cell information, furniture information, and illustration information described above, for example, a three-dimensional view as shown in FIG. 36 is obtained. It is displayed on the television 20 (see FIG. 1). In FIG. 36, illustration data according to the selected wall material is displayed for each wall, and furniture selected is arranged in a designated room. in this way,
In the three-dimensional view shown in FIG. 36, the wall materials and furniture selected by the customer are displayed as they are, so that the three-dimensional view easily matches the image of the customer as compared with the standardized three-dimensional view of the first embodiment shown in FIG. There are benefits.

By the way, the selection of the floor material, the wall material and the like in the present embodiment is performed on the screens of FIGS. That is, Western-style and Japanese-style taste information input on these screens and budget information determined before that (see FIG. 2).
Select a floor material or a wall material on the basis of (5). Furniture is selected on the screen shown in FIG. Regarding the direction of furniture, from the layout of the room, doors, bran,
It is automatically placed so that it does not overlap the window. The activation of the three-dimensional view shown in FIG. 36 is performed after the above-described input processing.

FIG. 5 shows wall materials and floor materials.
(C) A basic decision is made on the basis of customer preference information input on the screens shown in FIGS. 6 (a) and 6 (b) so that changes and reselections can be made on the screens of FIGS. 28 and 29. You may. In this case, as in the case of the first embodiment, the image of the customer can be reflected to some extent even if the three-dimensional drawing is started immediately after the input of the floor plan information.

Further, as a lower layer pallet shown in FIGS. 9B and 9C, a pallet from which members and types can be selected may be prepared. For example, when the living room shown in FIG. 9B is selected, a pallet for selecting a flooring material and a wall material of the living room is displayed, and a floor plan is created according to the illustration data of the selected flooring material. Also, cell information is determined based on the illustration data of the selected wall material,
In addition, the pattern of the wall at the time of modeling is determined.

§3. Third Embodiment In the above-described first and second embodiments, a floor plan according to a customer's request can be quickly created and displayed. It is easy to confirm the image. Therefore, in the third embodiment, parts for the cut model are printed based on the data of the floor plan created in the first or second embodiment. The configuration of the third embodiment is basically the same as that of the first and second embodiments, but slightly differs in the way of holding image data for printing a part and its processing. .

First, how to hold image data and its processing in the third embodiment will be described. FIG.
Shows a print example of parts on the floor. This printing is performed using the data of the floor portion at the time of modeling, but printing of a groove M for inserting a wall part is added. The groove portion M is printed along the wall at a predetermined length and with a width that the wall part can insert.

On the other hand, as shown in FIG. 38 (b), the wall parts are printed together with the windows w and doors d,
The insertion part L to be inserted into is printed. In this case, for the window w and the door d, printing can be performed using the data at the time of modeling as it is, but for the insertion portion L, a new insertion margin corresponding to the groove portion M is formed at a portion in contact with the floor and printed. I do. By the way, in the state of the floor plan, for example, as shown in FIG. 38 (a), the walls of the rooms are connected, so that it is not possible to print as wall parts as they are. Therefore, in this embodiment, the image is separated at a portion intersecting with another wall and at a corner, and the separated image is printed as a separate part.
Therefore, in the floor plan shown in FIG. 38A, eight wall parts are formed by separating at the portions marked with triangles in FIG. FIG. 2B is a front view of the wall part. As for furniture, the display illustration data storage unit IM has image data of a development view for each piece of furniture, and reads out and prints out the image data for all furniture selected by the customer.

Here, FIG. 39 is a plan view of a parts sheet on which each part is printed. In the figure, P1 is a floor part, P2 to P9 are wall parts, and P10 is a furniture part. These are specified paper (somewhat thick paper)
Is printed on both sides. Furniture is printed in the form of a development view. In this case, for the double-sided printing, a printer having a double-sided printing function is used, or when a printer capable of printing only one side is used, printing is performed twice on one sheet of paper. Note that double-sided printing may be performed using a copying machine having a double-sided copying function.

If the parts sheet created as described above is cut out with scissors and cut out through the groove M, each part can be assembled as shown in FIG. 40. Model is created.
In addition, in this model, the pattern of the floor material and wall material desired by the customer is used, and the same image data as that of the door, window and furniture is used.
The model reflects the customer's image very well. Japanese Patent Application Laid-Open No. Hei 3-138938 ("Housing paper model making system") discloses a configuration in which blank paper or a mount on which a picture is drawn in advance is cut. A model cannot be formed.

(1) In the above description, each part was cut with scissors. However, if a cutter path (cutting path) is given to an automatic cutter, automatic cutting is possible.
In this case, when creating the image data of each part, a cutter path is formed for the boundary portion of the image data and the groove M, and this and the image data are stored together. Then, the printed parts sheet is attached to the automatic cutter, and thereafter, a cutter path is supplied to the automatic cutter. As a result, each part and the groove M are automatically cut.

(2) As a method of creating a part sheet,
The front and back part sheets may be printed on different papers, respectively, and these may be bonded directly or via appropriate thick paper. Further, with respect to a pair of wall parts, an expanded shape may be formed by connecting the upper edges thereof, and this may be printed. In this way, after printing and cutting on one sheet of paper, the wall part is formed only by folding from the upper edge.

[0110]

As described above, according to the present invention, a three-dimensional view corresponding to a floor plan can be displayed quickly and easily (claims 1 to 6).

Further, if the wall information is set as information about two adjacent walls and the two surfaces are set to have the same positional relationship in all cells, each cell can be used for two walls. It is sufficient to have information, and the amount of information for three-dimensionalization can be extremely reduced (claim 2).

If the type of floor material is stored as the type of floor and the type of wall member is stored as the type of wall,
Even if a floor material or a wall material is designated, the storage contents can be set according to the designation. Then, if the display mode is determined according to the wall material or the floor material, a display reflecting the type of the member is made (claim 3).

Further, when the display data and the display position data of the housing member such as furniture are stored, the layout of the housing member according to the contents of the floor information storage means and the wall information storage means and the housing member are displayed. The display mode can also be determined. Therefore, house members such as furniture can be displayed in the floor plan (claim 4).

An input means for inputting a user's request is provided. If the user selects a wall, a wall material, a floor, a floor material, furniture, or the like based on the input desired information, the user is provided with an input means. A layout or furniture according to the user's preference is displayed (claim 5).

Further, the display mode determining means determines the display mode of the inner and outer surfaces of the wall based on the storage contents of the floor information storing means and the wall information storing means. If the plane print data that can be cut out for the floor is created, a printed model based on the plane print data is cut out and assembled to easily create a house model desired by a customer (claim 6).
