Description

DESIGN APPARATUS FOR PATTERNS FOR WOVEN FABRICS, DESIGN METHODS, AND DESIGN PROGRAM <br> <br> <br> Patents - stay tuned to the technology DESIGN APPARATUS OF PATTERNS FOR WOVEN FABRICS,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to the creation of patterns such as clothing using a fabric.

In the design of clothes using the fabric, the shirring and the gathering are used for the three-dimensional design. Shearing is used to attach the sleeves to the trunk in three dimensions, and the gathers are used to seal the frills of the skirts and the like. In these cases, the lengths of the parts on both sides of the sewing line are different, and therefore the textile products such as clothes have a three-dimensional shape by sewing.

In this design, the shape of a part to be sealed with a shirring or gathers is determined, and a stitching indication is input as to which position of the part and which position is to be stitched. However, imagining the finished product from parts and suture marks is difficult for inexperienced patterners and designers. Therefore, the inventors of the present invention have made the present invention by examining the designing of the finished product while simulating the three-dimensional shape.

Examples of the present invention are shown below, but the present invention is not limited thereto.

[Example]

Figs. 1 to 9 show a fabric pattern making device 2 of the embodiment, a method of making a fabric pattern, and a creation program. In addition, the description relating to the creating apparatus 2 is directly applied to the creating method and the creating program, and the description about the creating method is also applied to the creating apparatus and the creating program. In the drawing, reference numeral 2 denotes a fabric pattern making device, and reference numeral 4 denotes a keyboard 6 connected to a stylus 7, a mouse 8, a menu 10, etc. as a user interface. A trackball or the like may be used instead of the mouse 8 or the like. The menu 10 provides the input menu to the user, and the user interface 4 interprets the user's input from the keyboard 6 to the mouse 8 as the modification of the pattern data with reference to the menu.

The pattern data storage unit 12 stores pattern data such as clothes using parts made of a fabric. In the pattern data, the sealing relationship between the shape of the parts and the parts is specified. In the sewn relationship, when the position of the two parts at the middle position of the sewing line and the position of the two parts are specified, this data is referred to as a sealed display. The auxiliary data such as the material, the elastic modulus, the thickness, and the color pattern may be stored for the parts. The simulation engine 14 three-dimensionally simulates the shape of the part after sealing along the sealing line in the pattern data. In this case, the entire garment may be simulated with respect to the pattern data of one garment, or only the parts around the three-dimensional sewing line such as shearing or gathering may be simulated by disregarding other parts of the garment. In the case of locally simulating the circumference of a three-dimensional sewing line, once the shape of the entire garment is simulated, and then the pattern data is changed around the three-dimensional sewing line, the three- May be simulated.

The simulation requires the mechanical properties of the part, that is, the elasticity ratio in each direction, which is stored in the pattern data or the default value. Then, the three-dimensional shape after the sealing is simulated in consideration of the dynamic force caused by the gravitational force acting on each part or the part having a different length, which is sealed by shearing or gathering, and the elasticity of the part. And stores the obtained three-dimensional simulation data in the 3D simulation data storage unit 16.

The database 18 stores existing pattern data, corresponding 3D simulation data, material data such as elastic modulus of material, data of color patterns mapped to the parts, and the like. The pattern data may be created by making modifications through the user interface 4 based on the existing pattern data read from the database 18 or may be designed from the beginning using the user interface 4 without using the database 18 good.

The monitor 20 simultaneously displays, for example, the image 21 of the pattern data and the simulation image 22 in parallel. The user can change the pattern data by specifying the type of input using the menu 10 and designating points or areas on the images 21 and 22 by the stylus 7 or the mouse 8. [ When the pattern data is changed, a new 3D simulation image is generated by the simulation engine 14, and the pattern data image 21 or the simulation image 22 is changed. In this case, when the user changes the pattern data, the pattern data before the change and the pattern data after the change are stored in the storage unit 12, and the simulation data before the change and the changed simulation data are similarly stored in the storage unit 16. The changed image is displayed on the monitor 20, and when the user confirms the change of the pattern data, the data in the storage units 12 and 16 are overwritten.

Fig. 2 shows the creation and simulation of the pattern data. The user creates pattern data or reads from the database and performs 3D simulation by the simulation engine. Here, the simulation simulates locally the periphery of the shirring or gathers, and when the user does not designate the stitching display, the stitching line is divided according to the default value to generate the stitching display, and when the user designates or changes If you do, you will have to make sure that the parts specified in the suture mark match. When a user specifies a color pattern to be mapped to a part, the 3D pattern maps the color pattern to the part.

When the pattern data and the simulation data are displayed on the monitor and the user approves, the data is outputted as pattern data and the process is terminated. When the user changes the pattern data, the pattern data is changed by a stylus, a mouse, or the like to any one of the pattern data on the monitor or the simulation data. The type of modification can be specified in the menu, and the user can change the shape by dragging the points or areas of the pattern data or simulation data, and can change the sealing relationship by adding / deleting the sealing mark . The modified data input by the user is analyzed as a change of the pattern data according to the menu, and the 3D simulation is again performed by the post-analysis data and displayed together with the pattern data after the modification.

In this manner, the user can create a pattern while viewing the finished product in a three-dimensional manner on the monitor in a plurality of sealed parts. The user can freely change the size, shape and sealing relationship of the parts. Therefore, three-dimensional design and patterning using shearing or gathers can be facilitated for a less experienced designer or designer. In the simulation, only the part of the part having the three-dimensionally sealed relation is locally simulated, so that the simulation can be performed at high speed. This prevents you from waiting for the user.

FIG. 3 shows a pattern creation program 30, which provides a menu for the user and interprets the user's input. The pattern data storing instruction 32 is an instruction for storing the pattern data as the shape of the part and the sealing relationship and the 3D simulation command 33 is a command for locally simulating the pattern data locally on the plurality of parts connected in a three- to be. The simulation data storing instruction 34 is an instruction for storing data obtained by the 3D simulation, and the simulation instruction 35 is an instruction for simultaneously displaying the pattern data and the 3D simulation data on the monitor simultaneously.

Figs. 4 to 9 show examples of patterning in the embodiment. Fig. 4 shows pattern data of a skirt having frills. In the lower side, the sewing relationship between the frills and the skirt main body is shown, and a sealing relationship is shown by lines between the parts. Fig. 5 is a 3D-simulated image of the lower part of Fig. 4 according to the sealing relationship, and the prills are longer than the skirt main body, so that they are deformed in three dimensions. The display of Fig. 5 may be displayed on the monitor alone. However, if the screen is divided and displayed simultaneously with the display on the upper or lower side in Fig. 4, the relationship between the pattern data and the finished product can be vividly displayed. Also, if you modify the pattern data or the finished product, you can see what changes will occur in real time.

The pattern data of Fig. 6 is obtained when the length of the frills is extended as compared with the pattern data of Fig. The simulation data is shown in Fig. 7, but the shape of the sealing portion is changed because the prills are long.

Fig. 8 shows pattern data of a sleeve and a trunk in a garment. A sewing indication is designated by a line perpendicular to the rim of the piece around an arm hole. The bottom line of Fig. 8 shows how each part is sealed. A 3D simulation of this is shown in Fig. 9, in which a three-dimensional silhouette is created by connecting the sleeves to the front and rear bodies by shearing. Here, when the position of the seal display is changed, the pattern data is changed and the 3D simulation image is changed accordingly.

In the embodiment, the following effects are obtained.

(1) Even a less experienced designer or patterner can facilitate three-dimensional design or patterning using shearing or gathers.

(2) The pattern data and the simulation data are displayed in parallel on the monitor, for example, at the same time, so that the user can change the pattern data from either side.

(3) When the pattern data is changed, the 3D simulation image of the finished product is also changed, so that the user can change the pattern data interactively.

(4) Because the simulation is local, it can be executed at high speed and in real time.
