[Print data]
Next, the print data stored in the print data storage unit 142 of this embodiment will be described. For example, the print data storage unit 142 stores print data corresponding to each interior / exterior material according to the structure of the print data table.
FIG. 2 shows an example of a print data table stored in the print data storage unit 142. As shown in the figure, in the print data table, one or more product identifiers are associated with each interior / exterior material identifier corresponding to one interior / exterior material. The product identifier associated with the same one interior / exterior material identifier indicates a product in which a different color pattern is applied to the interior / exterior material indicated by the common interior / exterior material identifier. Such a product identifier corresponds to, for example, a model number. Note that product information related to a product such as a product name may be included corresponding to each product identifier. In addition, print data is associated with each product identifier. The print data associated with the product identifier is data for printing the color pattern of the product indicated by the corresponding product identifier.

  FIG. 3 schematically shows an example of the unit print area PS corresponding to one print data. As the print data, the actual size of the unit print area PS is determined in advance as shown in the figure, in which one direction (horizontal direction) is the dimension x1, and the orthogonal direction (vertical direction) to the one direction is the dimension y1. . Here, a case where the dimension x1 is the short direction and the dimension y1 is the longitudinal direction is taken as an example.

FIG. 4 shows an example of the relationship between the decorative surface KS of the interior / exterior material and the unit print area PS corresponding to the print data.
In the description of the figure, the horizontal direction (left-right direction) is treated as the x-axis direction, and the vertical direction (up-down direction) is treated as the y-axis direction. In the following description, the x-axis direction and the horizontal direction or the left-right direction are treated as synonymous. Similarly, the y-axis direction and the vertical or vertical direction are treated as synonymous.
In the figure, eight unit print areas PS-1 to PS-8 are arranged as the unit print area PS.

A unit print area PS-2 is arranged below the unit print area PS-1 in the y-axis direction. At the position where the lower end portion of the unit print region PS-1 and the upper end portion of the unit print region PS-2 are in contact, the color pattern is continuous. Similarly, a position where the lower end of the unit print area PS-3 and the upper end of the unit print area PS-4 that are arranged adjacent to each other in the vertical direction are in contact with each other, the lower end of the unit print area PS-4 The position at which the upper end of the unit print area PS-5 touches, the position at which the lower end of the unit print area PS-6 and the upper end of the unit print area PS-7, and the unit print area PS-7 The color pattern is continuous at each of the positions where the lower end of the unit and the upper end of the unit print area PS-8 are in contact with each other.
That is, in the print data, when the unit print areas PS are arranged so as to be arranged in the y-axis direction, the color patterns of the unit print areas PS adjacent in the y-axis direction are continuous.

As the print data in which the color patterns of the unit print areas PS adjacent in the y-axis direction are continuous as described above, there are the following two types of color patterns of the unit print areas PS adjacent in the x-axis direction. is there.
One is print data (two-direction continuous print data) in which color patterns are continuous between adjacent unit print areas PS in the x-axis direction. The other is print data (one-direction continuous print data) in which no particular consideration is given to the continuity of color patterns between unit print areas PS adjacent in the x-axis direction.
As the former two-way continuous print data, for example, the color pattern may be a geometric pattern. In addition, the latter one-way continuous print data may include data that does not have an explicit regular pattern that can be recognized at a glance, such as wood grain.

In the figure, the former two-way continuous print data is taken as an example. In other words, the unit print area PS-3 adjacent to the left side of the unit print area PS-1 is shifted from the unit print area PS-1 by a dimension y1 / 2 (an example of a predetermined dimension) in the y-axis direction. It has become. Further, the unit print area PS-6 adjacent to the right side of the same unit print area PS-1 also has a positional relationship shifted from the unit print area PS-1 by the dimension y1 / 2 in the y-axis direction. As understood from this, the unit print regions PS adjacent in the x-axis direction are arranged so as to be shifted from each other by the dimension y1 / 2 in the y-axis direction. And in the state arrange | positioned in this way, a color design is continuing in the edge part of the unit printing area | region PS mutually aligned in the left-right direction.
Specifically, the color pattern is continuous at a position where the end portion of the upper half on the left side in the unit print region PS-1 and the end portion of the lower half on the right side in the unit print region PS-3 are combined. In addition, the color pattern is continuous at a position where the lower half end of the left side of the unit print region PS-1 and the upper half end of the right side of the unit print region PS-4 are combined.
In addition, the color pattern is continuous at a position where the upper half end portion on the right side in the unit print region PS-1 and the lower half end portion on the left side in the unit print region PS-6 are combined. In addition, the color pattern is continuous at a position where the lower half end of the right side of the unit print region PS-1 and the upper half end of the left side of the unit print region PS-7 are combined.
In other words, the print data is continuous when the upper half edge of the left side of the unit print area PS and the lower half edge of the right side of the unit print area PS are combined and the upper half of the right side of the unit print area PS. When the end portion of the left side and the end portion of the lower half on the left side are combined, they are continuous.

In this way, with respect to the color pattern of the print data, in forming the decorative surface by array printing in which a plurality of unit print areas PS are arranged by one print data, the unit in each of the x-axis direction and the y-axis direction Color patterns are made to be continuous at adjacent ends of the print region PS.
Thereby, about the decorative surface of the interior and exterior materials, the joint of the unit print area PS can be made into a natural state. In addition, for the unit print areas PS adjacent in the x-axis direction, since the color patterns are continuous with the unit print areas PS being shifted from each other, for example, the same color pattern in the horizontal direction corresponding to the x-axis direction. It is also difficult to understand that the pattern is repeated for each dimension x1. As a result, the color pattern of the decorative surface formed by the plurality of unit print areas PS can be made more natural.

For example, the unit print areas PS may be arranged in a matrix. In this case, similarly to the arrangement in the y-axis direction, the print data pattern may be formed so that the patterns of the two unit print areas PS adjacent on the left and right are continuous in the x-axis direction.
However, in the examples of FIGS. 3 and 4, a rectangular unit print area PS is formed depending on the print data, and the size x1 in the x-axis direction is larger than the dimension y1 in the y-axis direction as the size of the unit print area PS. short. In this case, when the unit print areas PS are arranged in a matrix as described above, the patterns of the two unit print areas PS adjacent on the left and right are continuous, but the repeated patterns of the color patterns in the vertical and horizontal directions are Some people become annoyed and some people feel annoyed. Therefore, if the color patterns are made continuous under the arrangement in which the unit print areas PS adjacent in the x-axis direction are shifted from each other as shown in FIG. 4, the repetitive pattern of the color patterns is prevented from becoming fine. Can do.

  The arrangement in which the unit print areas PS adjacent in the x-axis direction are shifted from each other in the y-axis direction is not limited to the pattern shifted by the dimension y1 / 2 as shown in FIG. For example, when the unit print areas PS adjacent in the x-axis direction are shifted upward or downward by the dimension y1 / 3, the color patterns of the unit print areas PS adjacent in the x-axis direction are made continuous. It's okay.

In the actual interior / exterior material, a color pattern printed by print data is applied as follows.
For example, in a printing factory, printing is performed with print data on a film drawn from a long film roll having a predetermined width. At this time, printing is performed in a printing direction in which the longitudinal direction (y direction) of the print data corresponds to the flow direction of the drawn film. Therefore, in the actual interior / exterior material, printing is performed so that the color pattern is continuous between the unit print areas PS along the film flow direction (printing direction (y direction)).
For example, by attaching a printed film roll to a target inner / outer material in a factory or the like for manufacturing an inner / outer material or a site where a house is built, for example, an inner / outer material as a product corresponding to one model number Is obtained.

In addition, in order to apply a decorative surface to the actual interior / exterior material, the following procedure may be used. That is, when the width of the interior / exterior material is equal to or less than the width x1 of the unit print region PS in the x-axis direction, for example, a film to be printed is prepared with a width x1 or less, and the y-axis direction in FIG. In correspondence with the flow direction of the film, printing on the film is performed using the print data. When applying a decorative surface to the interior / exterior material, the size of the decorative surface KS is arbitrarily cut out from the printed film. The film to be cut out may be one sheet or a plurality of sheets obtained by appropriately dividing the size of the decorative surface KS. In addition, the cut film may be attached to the inner and outer materials.
In addition, when the width of the decorative surface of the actual interior / exterior material is larger than the width x1 in the x-axis direction of the unit printing region PS, for example, the color pattern is continuous along the flow direction in the same manner as described above on the film of width x1 Then, printing is performed, and a necessary length is drawn out from the roll of this film according to the size of the portion serving as the decorative surface of the inner and outer materials, and the film is bonded to the inner and outer materials. At this time, along the y-axis direction of the part to be the decorative surface, after the film having a width of x1 was first attached to the inner and outer materials, the film was further fed out from the roll in accordance with the left end or right end of the attached film. Laminate the film.
Moreover, you may form a makeup | decoration surface by arrange | positioning and arrange | positioning the interior / exterior material of a width | variety narrower than the makeup | decoration surface which stuck the film. When the film is attached to the inner and outer packaging materials in such a procedure, the positions of the unit print areas PS in the films adjacent to each other along the x-axis direction are shifted without matching. Accordingly, for example, if the color pattern is not required to be continuous in the x-axis direction, such as wood grain, the repetition of the color pattern in the x-axis direction is not noticeable.
On the other hand, when reproducing a state in which the repetition of the color pattern is not conspicuous as described above in the virtual space, it is necessary to intentionally arrange the unit print areas PS, but the unit print areas PS are arranged as described above. By doing so, a realistic expression can be easily realized.

[Residential virtual space screen]
FIG. 5 shows an example of a house virtual space screen displayed on the display unit 106 of the house virtual space simulation apparatus 100 of the present embodiment.
In the residential virtual space screen of the figure, a residential virtual space area AR11 and an operation area AR12 are arranged.
The housing virtual space area AR11 is an area for displaying the housing virtual space. As an operation corresponding to the residential virtual space area AR11, an operation for changing the viewpoint can be performed. When the viewpoint is changed by the viewpoint changing operation, in the residential virtual space area AR11, the display of the residential virtual space is changed so as to be observed from the changed viewpoint.

The operation area AR12 is an area where an operator performs an operation. In the operation area AR12, necessary operation images are appropriately displayed according to the operation. Note that the operation area AR12 may be displayed so as to overlap with a part of the residential virtual space area AR11. In this case, by setting a predetermined transparency in the operation area AR12, a display mode in which a portion of the residential virtual space area AR11 located below the operation area AR12 can be seen through may be used.
In the operation area AR12 of the figure, a state in which an interior / exterior material selection operation area AR121 and a color pattern selection operation area AR122 are arranged is shown.

  The interior / exterior material selection operation area AR121 is an area that is first operated when selecting (specifying) an interior / exterior material to be changed in color pattern from among the interior / exterior materials of the house displayed in the virtual house space. is there. For example, an interior / exterior material selection screen for selecting an interior / exterior material is displayed in response to a predetermined operation on the interior / exterior material selection operation area AR121. The operator selects an interior / exterior material whose color pattern is to be changed by an operation on the interior / exterior material selection screen.

The color pattern selection operation area AR122 is an area where an operation for selecting the color pattern of the interior / exterior material that is currently selected as a color pattern change target is performed.
In the color pattern selection operation area AR122 of the figure, an example in which icons Icn1 to Icn8 are arranged is shown. The icons Icn1 to Icn8 are described as icons Icn unless otherwise distinguished.
The icons Icn1 to Icn8 respectively correspond to color patterns that can be selected for the interior / exterior material that is currently selected as a color pattern change target. In icons Icn1 to Icn8, images of corresponding color patterns are displayed. When there are a large number of color patterns that can be selected for the interior / exterior material, for example, the operator performs operations such as horizontal and vertical scrolling and page turning on the color pattern selection operation area AR122. Thus, the set of displayed icons may be changed.
The operator can perform an operation of selecting one icon Icn from the icons Icn arranged in the color pattern selection operation area AR122. In the example shown in the drawing, the icons Icn are arranged in a rhombus orientation as indicated by Icn1, Icn2, Icn4 to Icn8, etc. under a non-selected state. On the other hand, when the icon Icn is in a selected state, the icon Icn changes so as to be arranged in a square orientation as shown as an icon Icn3. Further, the icon Icn in the selected state is highlighted in a predetermined manner.

In the residential virtual space displayed in the residential virtual space area AR11, the selected interior / exterior material portion is displayed with a color pattern corresponding to the icon Icn selected in the color pattern selection operation area AR122. .
For example, when an operation for selecting another icon Icn other than the icon Icn3 is performed from the state shown in FIG. 3, the portion of the interior / exterior material selected in the residential virtual space has a color pattern corresponding to the selected icon Icn. Change.
Thus, the residential virtual space simulation device 100 of the present embodiment can easily change the color pattern of the interior / exterior material in the residential virtual space. Thereby, for example, a customer who wants to purchase a house can easily check various color patterns of the interior and exterior materials of the house virtual space of the house to be purchased.

In addition, in the present embodiment, print data used for printing on the actual interior / exterior material is used for drawing the color pattern of the interior / exterior material as described above.
In the present embodiment, for drawing the interior / exterior material in the residential virtual space so as to reflect the color pattern of the interior / exterior material as a product corresponding to a certain product identifier, for example, the following mode is adopted. be able to.
For example, a color pattern corresponding to a partial area of the unit print area PS corresponding to the print data can be drawn on the interior / exterior material portion in the house virtual space. In addition, a color pattern obtained by arranging a plurality of unit print areas PS can be drawn on the interior / exterior material portion in the house virtual space. Alternatively, a tile image corresponding to a predetermined dimension based on the print data can be generated and drawn so that the tile image is arranged on the interior / exterior material portion in the house virtual space.

For example, if the color pattern of the wood is taken as an example, the print data is of such a high quality that it cannot be distinguished from the wood grain of the actual wood even though it is printed on the actual interior / exterior material.
For this reason, by using print data for drawing the color pattern of the interior / exterior material, it is possible to improve the reality of the color pattern of the interior / exterior material in the virtual space. In the present embodiment, print data used for printing the actual interior / exterior material is used for drawing the interior / exterior material in the virtual space. For this reason, it is possible to draw the color pattern of the interior / exterior material with high quality without taking the trouble of newly creating drawing data.

  The print data may include texture information related to gloss, unevenness, etc. for expressing the texture of the decorative surface formed by printing. When drawing the interior / exterior material, the image processing unit 132 uses the texture information included in the print data, for example, the appearance of the interior / exterior material reflecting the reflection of light incident on the decorative surface of the interior / exterior material. Can be reproduced. In this case, the print data may be, for example, a plurality of print data in which a first layer indicating color and pattern information and a second layer indicating unevenness information are overlapped. Each corresponds to printing with an ink plate on an actual interior / exterior material and printing (shaping) with an embossed plate. Further, a mat coat printing or gloss coat printing layer for gloss or matte may be used instead of or in addition to the layer showing the unevenness information.

Further, as described above, the size of the unit print area PS formed by printing is defined in the print data. In addition, when drawing the interior / exterior material in the house virtual space, the house virtual space simulation apparatus 100 draws the color pattern so that the dimensions of the unit print area PS correspond to the dimensions of the interior / exterior material in the house virtual space. I do. That is, for example, if the dimensions x1 and y1 of the unit print area PS are Xmm and Ymm, respectively, the residential virtual space simulation device 100 prints on the part that actually occupies the area of the size of Xmm and Ymm in the residential virtual space. Using the data, a color pattern by the unit print area PS of Xmm and Ymm is drawn.
Thus, by drawing the interior / exterior material (dimension matching drawing) in which the dimensions of the unit printing area PS are made to match the dimensions of the house virtual space, for example, without performing image processing such as resolution conversion in the middle, Can draw interior and exterior materials in a residential virtual space.
Further, instead of the unit print area PS, the dimensions may be determined on the processed print data image in accordance with the above drawing method. For example, the color pattern corresponding to a partial area of the unit print area PS corresponding to the print data Is drawn on the interior / exterior material portion in the housing virtual space, the dimensions may be determined in a partial area, or a unit area (for example, a decorative surface KS) obtained by arranging a plurality of unit print areas PS. Dimensions may be defined.
Moreover, the residential virtual space simulation apparatus 100 according to the present embodiment can change the distance (viewpoint distance) from the viewpoint position to the house object in the viewpoint direction, in addition to changing the viewpoint of the residential virtual space. In accordance with such a change in the viewpoint distance, the image of the interior / exterior material in the house is enlarged or reduced. Along with such enlargement and reduction of the image, the decorative surface of the inner and outer materials is also enlarged and reduced. In the present embodiment, since the dimension matching drawing is performed, for example, even when the decorative surface of the interior / exterior material is enlarged or reduced, drawing can be performed using the same print data. In addition, with respect to a particularly enlarged decorative surface, it is possible to display a high-definition color pattern according to the definition of the print data.

  Further, in the case where the decorative surface is formed by the plurality of unit print areas PS in drawing the interior / exterior material, the residential virtual space simulation apparatus 100 has a continuous color pattern at a position where the end portions of the adjacent unit print areas PS are in contact with each other. Thus, the drawing is performed so that the unit print areas PS are arranged. That is, the residential virtual space simulation apparatus 100 applies the printing that forms the decorative surface with the plurality of unit printing regions PS to the real interior / exterior material described in FIG. 4 to the drawing process. Thereby, it becomes possible to make the color pattern of the interior and exterior materials in the residential virtual space natural. This effect is particularly effective when the interior / exterior material portion is enlarged and displayed.

[Example of processing procedure]
With reference to the flowchart of FIG. 6, the example of the process sequence which the housing virtual space simulation apparatus 100 of this embodiment performs in relation to the display of a house virtual space is demonstrated.

Step S101: For example, when displaying the house virtual space screen of a certain sale target house, the operator of the house virtual space simulation apparatus 100 displays the house design data of the house that displays the house virtual space on the house virtual space screen. Perform the specified operation.
In response to the operation for designating the house design data, the image processing unit 132 in the house virtual space simulation apparatus 100 acquires the house design data designated by the operation from the house design data storage unit 141.

Step S102: Also, the print data acquisition unit 131 acquires, from the print data storage unit 142, print data (initial use print data) to be used for the initial display of the virtual house space based on the house design data input in Step S101. To do.
The initial use print data may be predetermined for each interior / exterior material by default, for example. Alternatively, the housing virtual space simulation device 100 may obtain data (interior / exterior material color pattern selection data) reflecting the final selection result for the color pattern of the interior / exterior material in the house virtual space at the stage where the house virtual space screen is completed. The data may be stored in the storage unit 104. In addition, when the interior / exterior material color pattern selection data corresponding to the house design data acquired in step S101 is stored in the storage unit 104, the print data acquisition unit 131 acquires initial use print data as follows. It's okay. That is, the print data acquisition unit 131 may acquire print data corresponding to the color pattern indicated by the interior / exterior material color pattern selection data stored in the storage unit 104 as initial use print data.

  Step S103: The image processing unit 132 draws the house virtual space. At this time, the image processing unit 132 generates a three-dimensional image of the house based on the floor plan indicated by the house design data acquired in step S101, the arrangement of building materials, and the like. In addition, the image processing unit 132 draws the color pattern of the interior / exterior material in the three-dimensional image of the house using the initial use print data acquired in step S102.
