  In any of the conventional processing methods, if it is desired to imagine the state after processing before processing, there is no choice but to browse an image that becomes a document or an image that has been subjected to halftone processing. When actual processing is performed with such an ambiguous image, the resulting sculpture may differ from the image. The same problem can be applied to the case where some processing (for example, silk printing or pasting of a cutting sheet) is applied to the material to be processed in addition to engraving by sandblasting.

  Therefore, an object of the present invention is to provide a design system for confirming a processed image of a workpiece material before processing, and an apparatus, program, recording medium, and method used therefor.

  In order to solve the above problems, the present invention has the following features. The present invention is a design system for confirming a processed image of a material to be processed before processing, and includes first and second communication devices that can be connected via a network. Document data acquisition means for acquiring document data of a document related to the design of processing desired to be processed on the workpiece material, solid shape data acquisition means for acquiring three-dimensional shape data regarding the three-dimensional shape of the workpiece material, and document data acquisition First transmission means for transmitting the original data acquired by the means and the solid shape data acquired by the solid shape data acquisition means to the second communication device, wherein the second communication device performs the first transmission. Design data acquisition means for acquiring design data related to the design based on the original data transmitted from the means, and the three-dimensional shape transmitted from the first transmission means Based on the data, 3D data acquisition means for acquiring 3D data indicating all or part of the three-dimensional shape of the material to be processed, and 3D data acquisition means for a region to be designed on the material to be processed Processing area designation means for designating on the three-dimensional data acquired by the above, and rendering for rendering the design data acquired by the design data acquisition means by texture mapping to the area specified by the processing area designation means Means and a second transmission means for transmitting the two-dimensional image obtained by the rendering means to the first communication device.

  According to the present invention, design data is texture-mapped on an area to be designed on a workpiece material, and a two-dimensional image obtained by rendering is transmitted to the first communication device. Therefore, the image after processing of the workpiece material can be confirmed on the first communication device side. The user who operates the first communication device of the present invention may be a processor who processes the material to be processed, or may be a person who actually owns the material to be processed. For example, the present invention can be used for the purpose of a processing company explaining the contents of processing while receiving a two-dimensional image at a customer and receiving an order for processing. In addition, a customer who wants to request processing from a processing company or who wants to perform processing by himself / herself uses a personal computer or the like to be installed in a processing company, its affiliated company, service provider, etc. It can be used by connecting to a communication device, solidifying the image after processing, and ordering processing. The method of using the present invention is not particularly limited. The present invention is useful in all cases where a material to be processed is subjected to some design processing.

  Preferably, the workpiece material is a material to be engraved by sandblasting.

  In particular, when a work material is engraved by sandblasting, the work material is engraved, so careful judgment is required as to whether or not to process. If this invention is used, the engraving after a process can be imaged and it can be used effectively for judgment of whether to process.

  Preferably, the design data acquisition means trims an unnecessary portion of the document data as necessary, obtains a halftone image, and obtains a single color or a plurality of colors from the halftone image or an image obtained by inverting the halftone image. It is preferable to obtain color image data and obtain design data from the image data.

  The method of engraving using a halftone image is a conventional engraving method by sandblasting. If design data is created by combining inversion processing and coloring processing based on this halftone image, a two-dimensional image close to when it is actually engraved can be obtained when texture mapping is performed. This is effective in pursuing the reality of two-dimensional images. For example, it is effective for plain carving, face carving, line carving, photo etching, and etching color (a processing method in which flat carving, surface carving, line carving, and photo etching are colored).

  Preferably, the design data acquisition means recognizes the contour of the image appearing in the document data, trims unnecessary portions of the recognized image as necessary, and obtains a halftone image as necessary. It is preferable to obtain single-color or multi-color image data from the obtained image or the inverted image and obtain design data from the image data.

  As a result, the contour portion is expressed. In particular, when line engraving is used, the two-dimensional image can be brought close to the actual processed image.

  Preferably, the design data acquisition means trims an unnecessary portion of the image data as necessary, obtains single-color or multi-color image data from the obtained image or an inverted image, and obtains the image data from the image data. Get design data.

  This makes the two-dimensional image closer to the processed image when engraving methods that do not use halftone processing, such as flat engraving, surface engraving, line engraving, etching color, etc. using a cutting plotter. Can do.

  Preferably, the rendering unit texture-maps the design data to the region by changing the surface property information specified by the three-dimensional data corresponding to the design data for the region specified by the processing region specifying unit. Good. Preferably, the surface characteristic information may include at least one of surface color, diffuse reflectance, specular reflectance, and transparency.

  By such a texture mapping technique, a two-dimensional image in which design data is reflected on the surface can be obtained, and the image can be brought close to an actual processed image.

  Preferably, the rendering means changes the surface characteristic information corresponding to the region to the color specified in the design data when the surface color is changed, and reduces the diffuse reflection when the diffuse reflectance is changed. When changing the direction and changing the specular reflectance, it is preferable to change the direction so that the specular reflection is reduced, or when changing the transparency, the direction is such that the transparency is lowered.

  As a result, a highly realistic two-dimensional image is affected. In particular, it is effective when a plane carving, a face carving, a line carving, a photo etching, or an etching color is used as a processing method.

  Preferably, the first communication device further includes material specifying means for specifying work material information relating to the material of the work material, and the first transmission means also includes the work material information specified by the material specifying means. The rendering unit may adjust the amount of change in the surface characteristic information based on the workpiece information transmitted from the first transmission unit.

  As a result, the amount of change in the surface property information differs depending on the material of the material to be processed, so that texture mapping is performed according to the material, and the reality is further increased.

  Preferably, the rendering unit may further perform bump mapping on the area specified by the processing area specifying unit based on the design data.

  By performing bump mapping, it is possible to express a feeling of unevenness, so that processing methods such as two-stage engraving and blurring can be expressed with high reality.

  Preferably, the design data represents a contour of the design, and the rendering unit may tilt the normal line according to the contour portion.

  If the normal line of the contour portion is tilted, the unevenness appears at the boundary of the contour portion. Therefore, a processing method such as double engraving can be expressed with high reality.

  Preferably, the design data has a gradation, and the rendering unit may incline the normal line according to the gradation.

  By tilting the normal according to the gradation, a continuous unevenness can be expressed. For example, processing methods such as blurring can be expressed with high reality.

  Preferably, the rendering unit may further perform displacement mapping on the region designated by the processing region designating unit based on the design data.

  By the displacement mapping, a plurality of unevenness feelings having different heights can be expressed. Therefore, a processing method such as multi-stage engraving can be expressed with high reality.

  Preferably, the first communication device further includes engraving method designating means for designating processing method information relating to the engraving method, and the first transmission means also includes second processing method information designated by the engraving method designating means. The rendering unit may select a texture mapping method based on the processing method information transmitted from the first transmission unit.

  Thereby, texture mapping based on the processing method according to the instruction from the first communication device is performed, and an image after completion of the processing method desired by the user can be transmitted.

  Preferably, the three-dimensional shape data includes three-dimensional shape template information for designating a predetermined three-dimensional shape, and the first communication device further includes a three-dimensional shape template information storage unit for storing the three-dimensional shape template information, The second communication device further includes a 3D shape template database storage unit for storing 3D data corresponding to the 3D shape template information, and the 3D shape data acquisition unit is configured to use the 3D shape template when Corresponding stereoscopic shape template information is acquired from the template information storage means and transmitted to the first transmission means, and the three-dimensional data acquisition means is based on the stereoscopic shape template information transmitted from the first transmission means, Referring to the 3D shape template database storage means, the corresponding 3D data It may be obtained.

  In this way, by making the three-dimensional shape of the material to be processed into a template, it is possible to save time and effort for modeling each time in the second communication device. Therefore, a two-dimensional image can be provided quickly.

  Preferably, the three-dimensional shape data includes work material data that is a photographic image of the work material, and the second communication device uses the texture for obtaining the texture data related to the texture of the work material from the work material data. An acquisition unit may be further provided, and the rendering unit may texture-map all or a part of the three-dimensional data based on the texture data acquired by the texture acquisition unit.

  As a result, a two-dimensional image that reproduces the texture of the original workpiece material is obtained, and the reality is further increased.

  Preferably, the first communication device designates a correction item instruction for the rendered two-dimensional image transmitted from the second communication device, and causes the first transmission unit to transmit the correction instruction. It is preferable to further include a correction instruction designating unit.

  This facilitates a correction instruction to the second communication device. The correction instruction may be given by chat, e-mail, or telephone.

  Preferably, the second communication device may further include a correction instruction display unit for displaying a correction instruction transmitted from the first communication device.

  Thereby, the operator of the second communication device can cope with the correction.

  In this way, if a document template is used, even if the design sense is lacking, it is possible to create appropriate document data, which is useful.

  Preferably, the second transmission unit further transmits design data, three-dimensional data, and data relating to the region to the first communication device, and the first communication device has been transmitted from the second transmission unit. Based on the design data, the three-dimensional data, and the data related to the region, it is preferable to further include a three-dimensional image processing means for displaying an image in which the design data is texture-mapped on the region.

  Thereby, also in the 1st communication apparatus, since a three-dimensional image can be confirmed, the image in a different angle can be confirmed suitably.

  The first communication apparatus 1 acquires a document relating to a design of processing desired to be processed on the material to be processed as document data (step S101). For example, when a photograph to be processed is a document, digital data of the photograph becomes document data.

As shown in FIG. 6, when the material to be processed is an original article (here, a glass plate), the material to be processed is photographed with a digital camera or the like, and the material data to be processed is input to the first communication device 1. To do. The material data to be processed is preferably a plurality of data photographed from a plurality of angles.

  Next, the first communication device 1 includes processing method information indicating how to engrave the workpiece material, color designation data or color designation template information indicating the color after engraving, and an area where the workpiece material is to be processed (machining area) Area designation data or area designation template information indicating the material of the material to be processed and the material information on the material to be processed are acquired (step S103). “Color designation data” or “color designation template information” indicates the color when coloring after engraving and whether the surface is coated. “Area designation data” or “Area designation template information” indicates an area in which a workpiece is to be engraved. “Work material information” indicates the material of the work material (for example, glass, stainless steel, ceramics, etc.).

  “Processing method information” is information indicating a processing method. The “processing method” is roughly divided into two. The first is a halftone processing method using a masking sheet in which engraved portions are expressed by halftone dots as a masking sheet in sandblasting. The second is a cutting method that uses a masking sheet cut by a cutting plotter or manual work as a masking sheet for sandblasting. A document as shown in FIG. 5A is generally performed by a halftone processing method, but is not limited thereto. A document as shown in FIG. 5B is generally performed by a cutting method, but is not limited thereto. Furthermore, the processing method is divided into seven carving methods (plane carving, face carving, line carving, photo etching, double carving, multi carving, and blur carving). Except for photoetching, engraving can be performed by either a halftone processing method or a cutting processing method. Photoetching can be engraved only by a halftone processing method.

  7 to 13 are diagrams for explaining the seven carving methods. FIG. 7 is a diagram for explaining plain carving. In the flat carving, a sculpture as shown in FIG. 7A is obtained by digging the symbol portion 7a (see FIG. 7B). In addition, since fine irregularities are formed on the surface by sandblasting, the irregularities are exaggerated in the drawings (hereinafter the same). FIG. 8 is a diagram for explaining the surface carving. In the face carving, contrary to the flat carving, a sculpture as shown in FIG. 8A is obtained by digging a portion 7b other than the design (see FIG. 8B). FIG. 9 is a diagram for explaining line carving. In line engraving, a sculpture as shown in FIG. 9A is obtained by digging only the outline portion 7c of the symbol (see FIG. 9B). FIG. 10 is a diagram for explaining photoetching. In photo-etching, a halftone dot portion 7d (or a portion other than a halftone dot) is sandblasted using a halftone dot masking sheet (see FIG. 10B), so that an engraving as shown in FIG. can get. Coloring can be achieved by coloring plain carving, surface carving, line carving, or photoetching.

  FIG. 11 is a diagram for explaining the double engraving. In the two-stage carving, an arbitrary portion 7e such as the outline of a pattern is deeply carved, and then the mask sheet is peeled off, and the peeled portion 7f is carved shallowly to make the carved surface two steps (FIG. 11). (See (b)), a sculpture as shown in FIG. FIG. 12 is a diagram for explaining multi-stage engraving. In multi-stage carving, the mask sheet is divided into multiple parts depending on the design. Part of the mask sheet is peeled off to carve the deepest part 7g, then the next mask sheet is peeled off to carve the next deeper part 7h. The mask sheet is peeled off, and then the deep portion 7i is carved (see FIG. 12B). Typically, the mask sheet is carved so as to be deeper from the center of the pattern, as shown in FIG. A sculpture as shown in the above is obtained. FIG. 13 is a diagram for explaining blur engraving. In blur engraving, the upper and lower depths of the engraving surface 7j are added like a gradation by changing the method and strength of the abrasive (see FIG. 13 (b)), and the engraving as shown in FIG. 13 (a). Is obtained. In FIG. 13B, cross-sectional hatching is omitted. In the blur carving, a mask sheet used in either flat carving, face carving, line carving, double carving, or multi carving is used.

In the present embodiment, the surface characteristic information is represented by at least the normal of the polygon, the surface color, the diffuse reflectance, the specular reflectance, the transparency, and the height of the polygon at the time of displacement mapping. For example, the brightness of the surface of the workpiece is represented by diffuse reflectance, specular reflectance, and environmental reflectance based on the lighting model of the phone. The color of the surface of the workpiece is represented by the surface color. The transparency of the surface of the workpiece is represented by the transparency. The surface property information is necessary for rendering. The environmental reflectance may be used for texture mapping.

  Next, based on the area designation data or area designation template information transmitted from the first communication apparatus 1, the second communication apparatus 2 selects an area to be engraved on the workpiece material on the three-dimensional data. Designate (step S206). Next, the second communication device 2 designates a processing method for the material to be processed based on the processing method information transmitted from the first communication device 1 (step S207).

  Next, the second communication device 2 renders the three-dimensional data acquired in step S204 so that the design data specified in step S203 is texture-mapped in the area specified in step S206 (step S208). ). Finally, the second communication device 2 transmits a two-dimensional image obtained by rendering to the first communication device 1.

  The first communication device 1 receives the two-dimensional image sent from the second communication device 2 (step S107) and displays the two-dimensional image (step S108). Thereby, in the 1st communication apparatus 1, the image after a process of a to-be-processed material can be confirmed before a process.

  Next, a series of flows will be described using an example of a user interface.

  FIG. 15 is a diagram illustrating an example of a user interface displayed on the first communication device 1 that is executing the client program. Before reaching FIG. 15, the first communication device 1 uses an interactive interface to input document data, input a three-dimensional shape of a material to be processed (specify material to be processed), specify a region (specify region specification data). Designation), designation of the processing method, designation of the material of the workpiece, and designation of the color (designation of color designation data). FIG. 15 shows an example of a confirmation screen after interactive input is completed. Note that the display in FIG. 15 shows an example in which a three-dimensional template is not used.

  In the column a1, it can be confirmed that data “ABC.jpg” is designated as the document data. Note that the contents of the data are displayed with a small icon a11 so that the outline of the data can be understood (the same applies hereinafter). This data is image data used as a document. If the button a12 is clicked, the original data can be changed. If the file name or icon is clicked, the document data can be enlarged and displayed (the same applies hereinafter).

  In the column a2, it can be confirmed that data “BCD.jpg”, “CDE.jpg”, and “DEF.jpg” are designated as the material data to be processed. These three data are image data obtained by photographing the material to be processed from different angles. If the button a13 is clicked, the material data to be processed can be added.

  In the column a3, the selected processing method is displayed. Since the type of the processing method is determined in advance, the processing method is selected from the determined types. Here, it can be confirmed that plain engraving is specified when the halftone processing method is used. If the button a14 is clicked, the processing method can be changed.

  In the column a4, it can be confirmed that data “EFG.jpg” is designated as the area designation data. If the button a15 is clicked, the area designation data can be changed.

(5) When the engraving method is “multi-stage engraving”, the second communication device 2 performs processing to extract the contour line and leave the halftone dot portion as it is, and to set the depth of the portion surrounded by the contour line. The designated process is performed, and the process proceeds to step S409.
(6) When the engraving method is “blur engraving”, the second communication device 2 performs processing to extract the contour line and leave the halftone dot portion as it is, and to the halftone dot of the portion surrounded by the contour line A process of specifying the color gradation is performed, and the process proceeds to step S409.
The processing of (1) to (6) can be corrected as appropriate based on an instruction from the operator.

  In step S409, the second communication device 2 confirms whether the three-dimensional shape is an original or a template based on the three-dimensional shape type in the transmission data. If it is original, the second communication device 2 proceeds to the operation of step S410. On the other hand, if it is a template, the second communication device 2 proceeds to the operation of step S412.

  In step S410, the second communication device 2 refers to the transmission data, recognizes the file name of the color designation data, and reads the attached color designation data. Next, the second communication device 2 displays the color designation data (step S411).

  On the other hand, in step S412, the second communication device 2 recognizes the identifier of the color designation template with reference to the color designation template information in the transmission data. Next, the second communication apparatus 2 reads the color template data corresponding to the recognized identifier with reference to the color template database, and displays the color template (step S413). The color template may be character information such that the design is red and the characters are blue, or may be an image representing a color image taking a specific design as an example.

  Next, the second communication device 2 performs a display prompting the user to perform color processing on the images obtained up to step S409. In response, the user changes the color of the image. The second communication device 2 temporarily stores an image obtained as a result of the color designation performed by the user (step S414).

  Next, the second communication device 2 creates design data by converting the image obtained as a result of step S414 into a predetermined format capable of texture mapping, and stores the created design data (step S415). .

  FIG. 23 is a flowchart showing details of the operation of the second communication device 2 in step S204 of FIG. Hereinafter, the details of the operation of the second communication device 2 in step S204 of FIG. 4 will be described with reference to FIG.

  First, the second communication device 2 refers to the solid shape type in the transmission data and determines whether or not a solid shape template is used (step S501). When the template is used, the second communication device 2 recognizes the solid shape template information with reference to the transmission data (step S502). Next, the second communication device 2 acquires three-dimensional data corresponding to the recognized three-dimensional shape template from the three-dimensional shape three-dimensional template database (step S503), and proceeds to the operation of step S504. In step S503, the second communication device 2 may display that the template is used as shown in the column b3 of FIG.

  The three-dimensional template is not limited to one representing the three-dimensional shape of the finished product. A part of the processed material data such as a flat plate or a curved surface shape may be used as a three-dimensional template. For example, when the material to be processed has a large and complicated shape such as a table, it is difficult to create the material data to be processed, and it is difficult to obtain accurate three-dimensional data by modeling. In such a case, if you use a flat plate template and texture-map the design data to the 3D data corresponding to the template, you can create a processed image as if the table top plate was engraved. You can get enough. Thus, a part of the three-dimensional shape may be templated.

  On the other hand, when the template is not used, the second communication apparatus 2 refers to the processed material data file name in the transmission data, reads the corresponding processed material data (step S505), and displays the corresponding image. (Step S506). For example, in the example shown in FIG. 17, the corresponding image is displayed in the field b3. Next, the second communication device 2 performs a display for prompting the user to create three-dimensional data corresponding to the displayed image, and executes a manual modeling process (step S507). When the modeling process is completed, the second communication device 2 acquires the modeling result as three-dimensional data (step S508), and proceeds to the operation of step S504.

  When performing the modeling process, it is not necessary to model all the three-dimensional shapes of the workpiece material photographed in the workpiece material data. For example, if you have a complicated shape such as a table, you can model only the shape of the top plate to be engraved, obtain 3D data, and texture map the design image to the 3D data. It is possible to obtain an image after processing as if the tabletop was engraved. In this way, a part of the three-dimensional shape may be modeled.

  In step S504, the second communication device 2 displays a three-dimensional shape based on the three-dimensional data obtained in step S503 or S508. For example, as shown in the window b11 in FIG. 17 or the window b11 in FIG. 20, the three-dimensional shape is displayed by a simple method such as a wire frame, hidden line processing, or hidden surface processing.

  FIG. 24 is a flowchart showing in detail the operation of the second communication device 2 in step S205 of FIG. Hereinafter, the details of the operation of the second communication device 2 in step S205 of FIG. 4 will be described with reference to FIG.

  First, the second communication device 2 recognizes workpiece material information with reference to transmission data. Also, when the material to be processed is changed by clicking the button b22 in FIG. 17, the material information to be processed in the transmission data is changed (step S601). At this time, the second communication device 2 may store the transmission data so that the transmission data before the change and the transmission data after the change can be distinguished.

  Next, the second communication device 2 performs a display prompting the user to designate the machining surface to be engraved on the displayed three-dimensional data, and causes the user to designate the machining surface (step S602). Next, the second communication device 2 refers to the workpiece material information surface property database and reads the surface property information corresponding to the designated workpiece material information (step S603). In the workpiece material surface characteristic database, surface property information is defined in correspondence with the material of the workpiece.

  Next, the second communication device 2 designates the surface characteristic information read in step S603 as the surface characteristic of the processed surface (step S604). Next, the second communication device 2 displays an image corresponding to the material data to be processed, acquires a texture other than the processing surface by using a process of extracting a color such as a dropper, and the surface other than the processing surface. A characteristic is designated (step S605). The designation in step S605 is performed for each modeled polygon. Note that the processing in steps S601 to S605 can be appropriately modified by an operator.

  Next, the second communication device 2 reflects the designation of the surface characteristics on the three-dimensional data (step S606) and stores the reflected three-dimensional data (step S607).

  FIG. 25 is a flowchart showing details of the operation of the second communication device 2 in step S206 of FIG. The details of the operation of the second communication device 2 in step S206 of FIG. 4 will be described below with reference to FIG.

  First, the second communication device 2 refers to the transmission data, recognizes the three-dimensional shape type, and recognizes whether it is an original or a template (step S701). If it is the original, the second communication device 2 reads the area designation data designated in the transmission data (step S702) and displays an image corresponding to the area designation data (step S703). For example, as shown in the column b6 in FIG. 17, an image corresponding to the area designation data is displayed. Next, the second communication device 2 performs a display prompting the user to designate a polygon and a region corresponding to the surface to be processed, and designates the polygon and the region in accordance with the user input (step). S704). Note that the polygon specified in step S704 matches the machining surface specified in step S602. For example, as shown in the window b8 in FIG. 18, the polygon c1 and the area c2 are designated. Thereafter, the second communication device 2 proceeds to the operation of step S708.

  On the other hand, when the solid shape type is a template in step S701, the second communication device 2 refers to the transmission data, recognizes the region designation template information (step S705), and refers to the region template database. The corresponding area designation template is displayed (step S706). For example, as shown in the column b6 in FIG. 20, the template of the area is displayed. Next, the second communication device 2 performs a display prompting the user to designate a polygon and a region corresponding to the surface to be processed, and designates the polygon and the region in accordance with the user input (step). S707). For example, as shown in window b8 in FIG. 20, a plurality of polygons c3 and region c4 are designated. Thereafter, the second communication device 2 proceeds to the operation of step S708.

  In step S708, the polygon and area specified in step S704 or S707 are stored as texture mapping area data.

  FIG. 26 is a flowchart showing details of the operation of the second communication device 2 in step S207 of FIG. Hereinafter, the details of the operation of the second communication device 2 in step S207 of FIG. 4 will be described with reference to FIG.

  First, the second communication device 2 recognizes the processing method based on the processing method information in the transmission data (step S801), and displays the recognized processing method (step S802). For example, in FIG. 18, the processing method is displayed in the column b4.

  Next, the second communication device 2 determines whether or not the processing method is corrected (step S803). When the processing method is corrected, the second communication device 2 changes the processing method information in the transmission data (step S804). At this time, the second communication device 2 may store the transmission data so that the transmission data before the change and the transmission data after the change can be distinguished. For example, the processing method can be changed by clicking the button b26 in FIG. Next, the second communication device 2 temporarily stores the final processing method (step SS805).

  FIG. 27 is a flowchart showing details of the operation of the second communication device 2 in step S208 of FIG. Hereinafter, the details of the operation of the second communication device 2 in step S208 of FIG. 4 will be described with reference to FIG.

  First, the second communication device 2 reads the design data acquired in step S415 (step S901), reads the three-dimensional data acquired in step S607 (step S902), and reads the texture mapping area data acquired in step S708. (Step S903). Next, the second communication device 2 reads the material information to be processed obtained in step S601 (step S904).

  Here, the color and brightness of the processed surface when engraving by sandblasting is performed will be considered. If the processed surface is glass, the engraved surface will be whitish, diffuse reflection will be large, specular reflection will be small, transparency will be reduced, but some transparency will remain. If the processed surface is stainless steel, the engraved surface becomes whitish, diffuse reflection increases, specular reflection decreases, and the transparency is the same as before processing. Diffuse reflectance and specular reflectance differ between glass and stainless steel. Even with the same whitish surface color, the color is slightly different. Therefore, changing the surface property information of the processing region uniformly based on the design data may lack realism. Therefore, the state after engraving can be reproduced more realistically by adjusting the amount of change in the surface characteristic information in accordance with the material of the processing region. Therefore, the second communication device 2 refers to the material-surface property change amount database that defines the change amount of the surface property according to the material, and changes in the surface property corresponding to the material read in step S904. The amount is recognized (step S905). FIG. 28 is a diagram illustrating an example of a material-surface property change amount database. As shown in FIG. 28, for each material such as glass or stainless steel, a change amount of the surface characteristic corresponding to the color of the design data is defined. In addition, the material-surface property change amount database is obtained by empirical values in most cases.

  Next, the second communication device 2 recognizes the processing method acquired in step S805 (step S906). Next, the second communication device 2 selects a texture mapping method according to the processing method (step S907).

  FIG. 29 is a flowchart showing details of the operation of the second communication device 2 in step S907. The second communication device 2 determines whether the processing method recognized in step S906 is “plain carving, face carving, line carving, or photo etching”, “double carving”, or “blur carving”. It is judged whether there is "multi-stage carving". In the case of “plain carving, face carving, line carving, or photo etching”, based on the amount of change in the surface property information recognized in step S905, at least the surface color, diffuse reflectance, specular reflectance, or transparency The image mapping which is the texture mapping to change any one is selected (step S1002). Which surface property is to be changed is determined in advance in the material-surface property change amount database. However, the operator may designate each time.

  In the case of “two-stage engraving”, the second communication device 2 selects a bump mapping that inclines the normal of the contour of the processing area to the inside of the surface to be engraved, in addition to the image mapping defined in step S1002. (Step S1003). Next, the second communication device 2 recognizes the outline of the machining area where the normal is inclined by the image recognition technique, and temporarily stores which area the normal is inclined (step S1004). For example, the second communication device 2 recognizes the contour line, and the normal of the portion corresponding to the contour line is tilted vertically inside the design image. By inclining the normal line of the contour of the processing area, rendering can be performed as if a dent is formed inside the contour.

  In the case of “blur engraving”, the second communication device 2 selects the bump mapping that inclines the normal of the processing area in accordance with the gradation applied to the design data in addition to the image mapping defined in step S1002. (Step S1005). The second communication device 2 defines a normal inclination amount according to the gradation color value, and temporarily stores the normal inclination amount according to the color (step S1006). For example, when the gradation from white to black is used, the second communication device 2 temporarily stores the amount of normal inclination according to the rule that the normal is inclined as it approaches white. By inclining the normal of the processing area according to the gradation, rendering can be performed as if the dent of the processing area is continuously changing.

  In the case of “multi-stage engraving”, the second communication device 2 subdivides the polygons in the area in addition to the image mapping defined in step S1002, and changes the height of the polygons according to the unevenness of the multi-stage engraving. Displacement mapping is performed (step S1007). The second communication device 2 recognizes the depth of the step engraving based on the color density of the design data, recognizes the height of the polygon at the time of displacement mapping, and temporarily stores it (step S1008). For example, when the second communication device 2 recognizes the depth of the step engraving based on the color difference from white to black, the height of the polygon is reduced according to a rule that the height of the polygon is lowered as it is closer to black. Save it temporarily. Since the height of the polygon in the processing area changes, the unevenness when multi-stage engraving is actually expressed and rendered.

  The amount of normal inclination and the height of the polygon during displacement mapping are also treated as surface characteristics.

  After step S907, the second communication device 2 recognizes the processing area designated by the texture mapping area designation data obtained in step S708. The second communication device 2 uses the surface characteristics (surface color, diffuse reflectance, specular surface) obtained in steps S905 and 907 as the surface characteristic information in the recognized processing region in the three-dimensional data read in step S902. Changes are made based on the amount of change in reflectance, transparency, normal slope, and polygon height during displacement mapping (step S908).

  Next, if the operator desires the second communication device 2, the second communication device 2 further changes the surface property information changed in step S908 according to the correction of the surface property (step S909). ).

  Then, the second communication device 2 designates the viewpoint and the light source (step S910), for example, renders by the ray tracing method (step S911), and stores the two-dimensional image obtained by the rendering (step S912). The second communication device 2 returns to the operation of step S910 when the operator gives an instruction to obtain a two-dimensional image from another viewpoint (step S913). When one or more necessary two-dimensional images are obtained, the second communication device 2 proceeds to the operation of step S209 in FIG. 4 and transmits the obtained two-dimensional image to the first communication device 1.

  FIG. 30 is a flowchart showing the operation of the first communication device 1 after receiving a two-dimensional image. Hereinafter, the operation of the first communication device 1 after receiving the two-dimensional image will be described with reference to FIG.

  The first communication device 1 displays the received two-dimensional image (step S1101), displays a message asking the user whether correction is necessary, and determines whether there is a correction instruction (step S1101). S1102). When there is a correction instruction, the first communication apparatus 1 starts up the image processing software (step S1103), displays the correction instruction to be written in the two-dimensional image, and the correction instruction is input by the user ( In step S1104, the two-dimensional image in which the correction instruction is written is stored (step S1105), and the corrected two-dimensional image data (correction data) is transmitted to the second communication device 2 (step S1106).

  FIG. 31 is a flowchart showing the operation of the second communication device 2 after receiving the correction data. Hereinafter, the operation of the second communication device 2 after receiving the correction data will be described with reference to FIG.

The second communication device 2 receives the correction data (step S1201) and displays the correction data (step S1202). As shown in FIG. 19 and FIG. 20, the second communication device 2 displays a screen on which a design image is simply pasted in a three-dimensional shape, and appropriately designs data, three-dimensional data, work material information, and processing. The operator is prompted to correct the area and processing method (step 1203). After the correction, the second communication device 2 performs rendering (step S1204), stores the two-dimensional image data, and transmits it to the first communication device 1 (step S1205).

  According to the present embodiment, the design data is texture-mapped on the region to be designed on the workpiece material, and the two-dimensional image obtained by the rendering is transmitted to the first communication device 1. Therefore, the image after processing of the workpiece material can be confirmed on the first communication device 1 side. In particular, when a work material is engraved by sandblasting, the work material is engraved, so careful judgment is required as to whether or not to process. If this embodiment is used, the engraving after processing can be imaged, and it can be effectively used to determine whether or not to perform processing.

  The method of engraving using a halftone image is a conventional engraving method by sandblasting. If design data is created by combining inversion processing and coloring processing based on this halftone image, a two-dimensional image close to when it is actually engraved can be obtained when texture mapping is performed. This is effective in pursuing the reality of two-dimensional images. For example, it is effective for plain carving, face carving, line carving, photo etching, and etching color (a processing method in which flat carving, surface carving, line carving, and photo etching are colored).

  By expressing the contour portion by image recognition, when line engraving is used, the two-dimensional image can be brought close to the actual processed image.

  According to the present embodiment (see steps S407 to S408), engraving methods that do not use halftone processing, for example, when performing flat engraving, surface engraving, line engraving, etching color using a cutting plotter, etc. The two-dimensional image can be brought close to the processed image.

  By using at least one of surface color, diffuse reflectance, specular reflectance, and transparency as the surface characteristic information, the reality of texture mapping is improved. In addition, by changing the amount of change in the surface characteristic information according to the difference in the material of the workpiece material, texture mapping according to the material is performed, and the reality is further increased.

  Bump mapping and displacement mapping can express unevenness, which is useful for carving at different depths.

  By making the three-dimensional shape of the workpiece material into a template, it is possible to save time and effort for modeling each time in the second communication device 2. Therefore, a two-dimensional image can be provided quickly.

(Modification)
FIG. 32 is a diagram illustrating an operation of the first communication device 1 when document data is created using a template. Hereinafter, the operation of the first communication apparatus 1 when creating document data using a template will be described. The operation shown in FIG. 32 may be performed in step S101 of FIG.

  First, the first communication apparatus 1 displays a message asking whether or not to use a document template (hereinafter referred to as a document template), and determines whether or not the use is instructed (step S1301). When the use is not instructed, the first communication apparatus 1 causes the user to capture an original image (step S1302), specify a color (step S1303), and input a character (step S1304), and copy the original data.

At this time, the three-dimensional image can be rotated as appropriate, or can be viewed from a predetermined angle. The first communication device determines whether or not to render in accordance with an instruction from the user (step S1404). When rendering, the first communication device renders (step S1405) and displays a two-dimensional image (step S1406). ).

  In the above embodiment, the processing area is specified on the first communication device 1 side. However, since the area that can be processed is limited, the first communication device 1 specifies the processing area. Instead, the second communication device 2 may designate the processing area in accordance with an operator instruction. That is, designation of the processing area on the first communication device 1 side is not essential in the present invention.

  In the above embodiment, the color is designated on the first communication device 1 side.

However, in the present invention, the material to be processed is a material to which a cutting sheet is attached or silkscreen printing is applied. The processing method of the workpiece material is not particularly limited. In the case of pasting a cutting sheet or silk screen printing, if only the surface color is changed among the surface characteristics in texture mapping, realism can be pursued, so the processing becomes lighter than in the above embodiment. In the case of pasting a cutting sheet or silk screen printing, various color schemes are specified in the design data compared to engraving, but if the above embodiment is used, the image after processing can be confirmed. it can.

  When an image with inferior image quality is obtained as document data, such as the Internet or a portable photo, the second communication device 2 may automatically correct the image by a known image correction method.

  When creating the design data, the second communication device 2 cuts off either one of the photo and text, or the original data in which the text and text overlap. It is recommended to correct automatically.
