Description

Sewing simulation method and device

Technical Field

The following embodiments relate to a sewing simulation method and apparatus.

Background

Although the garment (garment) is presented in a 3D form while being worn on the body, in practice, it is closer to a 2D form since the garment corresponds to a combination of pieces of fabric (fabric) cut according to a 2D pattern. The fabric as the material of the garment is relatively soft, and thus its shape may vary according to the shape or movement of the wearer's body.

In the 3D simulation, the lines connected by the sewing between the patterns may include at least two sewing lines. In order for a user to modify a sewing line, the user may need to select a desired sewing line from a plurality of sewing lines. Accordingly, a technique for allowing a user to select a sewing line that the user wants to edit in a 3D simulation may be particularly important.

The foregoing description has been presented in the context of this disclosure and is not an admission that the disclosure is prior art, or at least generally known in the art.

Detailed Description

The specific structural or functional description disclosed in the present specification is for the purpose of illustrating embodiments according to technical concepts only, and the embodiments may be embodied in various other forms and are not limited to the embodiments described herein.

The terms first or second, etc. can be used to describe various components, however, these terms are only used to distinguish one component from other components. For example, a first component can be named as a second component, and similarly, a second component can also be named as a first component.

When it is stated that one constituent element is "connected" or "coupled" to another constituent element, it can be directly connected or attached to the other constituent element, however, it can also be understood that other constituent elements exist therebetween. In contrast, when a component is described as being "directly connected" or "directly coupled" to another component, it is understood that no other component exists therebetween. Expressions describing a relationship between constituent elements such as "between", "directly between" or "adjacent", "directly adjacent", etc., should be construed as being similar.

Where not otherwise stated in the context, singular expressions include plural meanings. In the present specification, the terms "include" or "have" are used to express that there are features, numerals, steps, operations, components, parts, or combinations thereof described in the specification, and do not exclude that there are one or more other features, numerals, steps, operations, components, parts, or combinations thereof, or additional functions.

All terms used herein, including technical or scientific terms, have the ordinary meaning as understood by one of ordinary skill in the art without further definition. The terms commonly used in the art, which are commonly defined as dictionary definitions, should be understood as meanings consistent with the common contents of the related art, and should not be over-idealized or formally construed without explicit mention in this application.

The embodiments are described in detail below with reference to the accompanying drawings. Like reference symbols in the various drawings indicate like elements.

Although not shown in the drawings, the 3D garment and the 2D pattern may be composed of a mesh including a plurality of polygons. According to an embodiment, various modeling may be performed on the grid. For example, the vertices of the polygons included in the mesh may be point masses (points), and the sides of the polygons may be represented as springs having elasticity connecting the masses thereof. Thus, for example, a 3D garment according to an embodiment may be modeled by a Mass-Spring Model (Mass-Spring Model). Depending on the characteristics of the fabric material used, the spring may have corresponding values for tensile (stretch), shear (shear) and bending (bending) resistance (resist).

Alternatively, the mesh may be modeled by a strain (strain) model. For example, polygons included in the mesh may be modeled as triangles or polygons having four or more sides. In some examples, where it is desirable to model a 3D volume, the mesh may be modeled as a 3D polyhedron.

The polygon vertices included in the mesh may be moved by external forces (e.g., gravity) and internal forces (e.g., stretching, shearing, and bending). When the force applied to each vertex is obtained by calculating the external force and the internal force, the displacement and the moving speed of each vertex can be obtained. The movement of the garment can be simulated by the movement of the vertices of the polygons making up the mesh in each time step. For example, when a garment configured as a polygonal mesh is overlaid on a 3D component, a natural 3D virtual garment based on physical laws can be implemented. The vertices of the polygons included in the mesh may move according to the action of external forces (e.g., gravity, etc.) and internal forces (e.g., tension, shear, and bending). When the force applied to each vertex is obtained by calculating the external force and the internal force, the moving speed and displacement of each vertex can be obtained. Further, the movement of the virtual garment may be simulated based on the movement of the mesh polygon vertices in each time step. When a 2D pattern formed by a polygonal mesh is overlaid on a 3D avatar, a 3D virtual garment based on the natural appearance of the laws of physics can be realized.

For example, the 3D garment according to an embodiment may include at least one of a virtual garment adapted to a body size of the user, a virtual garment for a 3D virtual character, and a virtual garment for a 3D virtual avatar.

A 3D garment can be created by contacting and joining, i.e. "sewing", one of the contours of a 2D pattern with one of the contours in another 2D pattern. The sewing of the virtual garment may be accomplished by attaching one mesh in the outline of the 2D pattern to another mesh in the outline of another 2D pattern to be sewn to create one 3D garment. More specifically, on the outlines of two 2D patterns, there may be polygon vertices of the mesh constituting the 2D patterns thereof, and when a user inputs an outline and a length (hereinafter, referred to as "sewing line") desired to set sewing, sewing of a virtual garment may be achieved by welding (welding) the polygon vertices of the mesh located on the sewing line in each 2D pattern.

The start and end points of each sewing line may be vertices of polygons of a particular mesh. When the number of polygon vertices input by the user on each sewing line is not uniform, the mesh of the 2D pattern may be updated to generate a new mesh so that the numbers of polygon vertices on the two sewing lines match each other.

The sewing simulation method will be described below.

According to an embodiment, a simulation apparatus may receive a selection input for displaying in stages at least one cut piece (piece) hierarchically included in a design item and visual depths (visual depths) of a plurality of patterns included in the pattern piece (step 110).

The design may be the shape, form, color, or a combination thereof of the article and may create an aesthetic by vision. Further, an item may refer to an individual and specific tangible event. The design article may refer to an article that creates an aesthetic through vision. For example, the design items may include clothing, shoes, accessories, bags, hats, and the like. The design article may include at least one panel. For example, if the design item is a garment, the garment may include a top garment and a bottom garment. The panel may include a plurality of patterns. For example, if the panel is a T-shirt of a top panel, the pattern may include a front pattern, a back pattern, a sleeve pattern, and the like.

According to an embodiment, a 3D exploded view may be generated based on the visual depth such that a distance between at least one pattern of the plurality of patterns and at least one other pattern is increased (step 120). The 3D exploded view (expanded view) may be a view that separates a plurality of patterns included in a design item from each other in a 3D simulation. For example, in a 3D exploded view, the simulation device may adjust the distance between the panels to increase the distance between the panels. In another example, in the 3D exploded view, the simulation device may adjust the distance between the patterns to increase the distance between the patterns. Thus, the user can perform delicate work such as modifying the sewing line, material, or size, etc. of each pattern included in the design image pattern.

When the number of panels included in the design article is two or more, the simulation apparatus according to an embodiment may be adjusted to increase the distance between the panels. After increasing the distance between the panels, the simulation apparatus may be adjusted to increase the distance between the plurality of patterns included in each panel, thereby generating a 3D exploded view. Since the 3D exploded view of the present invention is adjusted to increase the distance between the plurality of patterns and keep the shape of the existing 3D garment as unchanged as possible, the user can expect visual effects, which help to easily understand the entire 3D garment and easily perform design work.

According to an embodiment, the simulation device may store sewing line matching information based on at least one sewing line input to the 3D exploded view, wherein the sewing line matching information includes matching relationships between sewing lines existing on different pattern contours. The simulation apparatus may receive sewing line information from the user terminal. The sewing line information is related to the sewing line and may include sewing line matching information, sewing line generation information, and/or sewing line modification information. The user can perform an operation of generating a sewing line in the 3D exploded view. In addition, the user may perform an operation of modifying the sewing line in the 3D exploded view. The simulation apparatus according to an embodiment may receive sewing line information including a user's work related to a sewing line and store the sewing line matching information. The sewing line matching information may include matching relationships between sewing lines existing on the contours of different patterns. Since there may be more than two sewing threads on one thread in the 3D simulation of the design object, the more than two sewing threads present in each different panel in the 3D exploded view may be matching threads. In particular, since the pattern is connected along a plurality of matching sewing lines, a pair of matching sewing lines may form one line. Accordingly, a plurality of matched sewing lines may be represented as one line in the 3D simulation of the design article. The simulation apparatus according to an embodiment may recall the stored sewing line matching information to display a plurality of sewing lines in the 3D exploded view.

The sewing line matching information according to an embodiment may be information stored in the simulation apparatus or the user terminal. For example, after a user designs a particular garment and enters sewing threads, data relating to the garment design may be stored. In this process, sewing thread matching information corresponding to the design of the garment may also be stored. When the user calls the dress design file, the simulation apparatus may also call sewing line matching information corresponding to the dress design to display the sewing lines in the 3D exploded view.

According to an embodiment, a plurality of sewing lines related to a selected panel determined based on an input of selecting one panel of at least one panel may be displayed on the 3D exploded view based on sewing line matching information including matching relationships between the sewing lines existing on different pattern contours (step 130). The design article may include at least one panel. When an input of a user selecting one of the at least one panel is received, the simulation apparatus may display a plurality of sewing lines included in the selected panel. Referring to fig. 2a, the panel may be a T-shirt. The user may select T-shirt panel 210. In this case, the T-shirt may be the selected panel. The simulation apparatus according to an embodiment may display all sewing lines included in a selected panel. The simulation apparatus according to an embodiment may display the sewing lines included in the selected panel and/or the sewing lines matched with the sewing lines. Thus, the user can stably execute the sewing line editing operation for the specific part. In another example, the user may select a top panel when one panel includes a top panel and a bottom panel. In this case, the simulation apparatus may display all sewing lines related to the upper garment panel and not display the sewing lines included in the lower garment panel. The simulation apparatus may generate a 3D exploded view of the garment piece by adjusting so as to increase the distance between the plurality of patterns included in the selected garment piece. Conversely, the simulation device may not generate a 3D exploded view of the unselected lower garment pieces.

The simulation apparatus according to an embodiment can generate a 3D exploded view of a selected panel in a sewing line editing mode. In addition, the simulation apparatus may not output the non-selected parts on the screen. Therefore, in the sewing line edit mode, only the 3D exploded view of the selected cut piece can be output on the screen. The sewing thread editing mode may refer to a mode in which a user can edit a sewing thread in a 3D simulation. In the sewing thread edit mode, the user can modify the length of the sewing thread or delete the sewing thread.

The simulation apparatus according to an embodiment may display a sewing line and a guide line connecting the sewing line in a sewing line edit mode, wherein the sewing line is associated with a selected panel determined based on an input of selecting one panel of at least one panel at a selected and input visual depth. Further, the simulation apparatus may not display at least one of the parts other than the selected part. Therefore, the simulation apparatus can output only the parts selected by the user, the sewing lines and the guide lines related to the parts on the screen, so that the user can collectively edit only the parts selected by the user as the editing target.

The simulation apparatus according to an embodiment may display a plurality of sewing lines and guide lines connecting the sewing lines in a sewing line edit mode, wherein the sewing lines are associated with a selected pattern determined based on an input of selecting one of a plurality of patterns at a visual depth selected and input. Further, the simulation apparatus may not display the sewing thread related to at least one pattern other than the selected pattern and the guide line connecting the sewing threads. Further, the simulation apparatus may not display the parts not including the selected pattern. Therefore, the simulation apparatus can display only the parts including the selected pattern, the sewing lines and the guide lines associated with the selected pattern. Further, the simulation apparatus may not display the parts, sewing threads, and guide lines regardless of the selected pattern. Thus, the user can collectively edit the selected pattern as the editing target.

The simulation apparatus according to an embodiment can generate a 3D exploded view of a selected panel in a sewing line generation mode. In addition, the simulation device may generate a 3D exploded view of the unselected garment pieces. Therefore, in the sewing thread generation mode, all the parts of the design article can be represented in the 3D exploded view. The sewing thread generation mode may be a mode in which a user can generate a sewing thread in a 3D simulation. The user can generate a new sewing thread on the pattern in the sewing thread generation mode.

The simulation apparatus according to an embodiment may display a plurality of sewing lines related to a selected panel determined based on an input of a selected one of at least one panel at a selected and input visual depth in a sewing line generation mode. Further, the simulation apparatus may display at least one of the parts other than the selected part. The at least one of the panels other than the selected panel may include a panel other than the selected panel among a plurality of panels included in the design article. Accordingly, the simulation apparatus can display a 3D exploded view of all the panels included in the design item in the sewing line generation mode. This is because patterns included in different panels can be connected to each other. Therefore, unlike the sewing line editing mode, the simulation apparatus can display not only the selected part but also 3D exploded views of other parts in the sewing line generation mode.

The generation and editing of the sewing thread will be described in detail below.

The user can create a new sewing thread on the pattern. In addition, existing or newly generated sewing threads may be edited.

The simulation apparatus according to an embodiment may generate a first sewing line as at least a part of an outline of a first pattern and a second sewing line as at least a part of an outline of a second pattern, which may be matched with the first sewing line, based on a selection input of a user. The first pattern and the second pattern may be patterns included in the same panel, or may be patterns included in different panels. The simulation apparatus according to an embodiment may generate a guide line connecting the first sewing line to the second sewing line.

The user's selection input may include a start point and an end point of the sewing thread. The user can input the start and end points of the sewing thread in the pattern. The simulation apparatus according to an embodiment may generate a sewing line connecting the start point and the end point. The length of the generated sewing thread may not necessarily match the length of the pattern profile or the distance between two points on the profile. The length of the generated sewing thread may be determined based on the start point and the end point input by the user. The lengths of the sewing threads matching each other may be the same or different. For example, the length of the first sewing line may be the same as or different from the length of the second sewing line.

The simulation apparatus according to an embodiment may edit at least one of the first sewing line and the second sewing line. Editing the sewing thread may include modifying the length of the sewing thread or deleting the sewing thread. Modifying the length of the sewing thread may be accomplished by changing the position of one end of the sewing thread. When the user inputs the movement of the end point of the sewing thread, the simulation apparatus may modify the length of the sewing thread and output the modified sewing thread in the 3D simulation. In the case of modifying the length of at least one of the first sewing line or the second sewing line, the simulation device according to an embodiment may change the guide line connecting the first sewing line and the second sewing line. The simulation means may change the guide line according to the modified length of the sewing thread. When the length of at least one of the first sewing line and the second sewing line is modified, the length of sewing the two patterns may be modified. Deleting the sewing thread may be an operation of deleting a pair of matched sewing threads. The simulation apparatus may delete the selected pair of sewing lines based on a selection input of the user. In the case of generating a selected pair of sewing threads, the simulation means may delete the matching relationship of the pair of sewing threads and delete the guide line connecting the pair of sewing threads in the 3D simulation.

The simulation apparatus according to an embodiment may display a plurality of sewing lines related to a selected pattern determined based on an input of selecting one of the patterns on the 3D exploded view based on the sewing line matching information (step 130). Multiple patterns may be included in a panel. When the user inputs a selection of one of the plurality of patterns, a plurality of sewing lines included in the selected pattern may be displayed. Further, the simulation apparatus according to an embodiment may display a plurality of sewing lines included in the selected pattern and sewing lines respectively matched with the sewing lines. Referring to fig. 3a, a panel may be a T-shirt, and the T-shirt may comprise a plurality of patterns. The user may select a sleeve pattern from a plurality of patterns. In this case, the sleeve pattern may be a selected pattern. The simulation device may display all

sewing lines

330, 332 associated with the selected pattern. Further, the simulation apparatus may display a plurality of guide lines 331 associated with the selected pattern.

The simulation apparatus according to an embodiment may display a plurality of sewing lines associated with the selected pattern, and may not display a plurality of sewing lines that do not match the displayed plurality of sewing lines. For example, the simulation apparatus may display a plurality of sewing lines associated with the selected pattern as solid lines having a specific color. In addition, the simulation apparatus may not output sewing threads that do not match the displayed plurality of sewing threads onto the screen.

The simulation apparatus according to an embodiment may display a plurality of sewing lines associated with a selected panel, and may not display sewing lines that do not match the displayed plurality of sewing lines.

The simulation apparatus according to an embodiment may generate a plurality of guide lines connecting between sewing lines matched with each other based on the sewing line matching information. The guide line may include a line guiding the sewing lines matched with each other to be sewn. This will be described in detail below with reference to fig. 2 a.

The simulation apparatus according to an embodiment may display a guide line connected to the selected pattern. Further, the simulation apparatus may not display a guide line not connected to the selected pattern. By this, the simulation apparatus can output only the guide line related to the pattern selected by the user as the work object on the screen to allow the user to easily modify the sewing line.

The simulation apparatus according to an embodiment may display a guide line connected to a selected work piece. Further, the simulation apparatus may not display the guide line not connected to the selected panel. By this, the simulation apparatus can output only the guide lines related to the workpiece selected by the user as the object of the workpiece on the screen to allow the user to easily modify the sewing line.

Fig. 2a shows a T-shirt panel 210, a pattern 1 211, a pattern 2 212, a pattern 3 213, a pattern 4 214, a pattern 5, a pattern 6, a pattern 7 217, a sewing thread 1 232, a sewing thread 2 230, a guide thread 231, a sewing thread 3250, a sewing thread 4 252 and a guide thread 251 included in the T-shirt panel 210.

The sewing line matching information may include matching information between a first sewing line generated on at least a portion of an outline of the first pattern and a second sewing line generated on at least a portion of an outline of the second pattern based on a user's selection input in the 3D exploded view. Referring to fig. 2, the sewing line 1 232 existing on the contour of the pattern 2 212 and the sewing line 2 230 existing on the contour of the pattern 6 may be sewing lines matched with each other. In this case, the first pattern may be the pattern 2 212, and the first sewing line may be the sewing line 1 232. And, the second pattern may be the pattern 6, and the second sewing line may be the sewing line 2 230. When the user generates the sewing line 1 232 on the contour of the pattern 2 212 and then generates the sewing line 2 230 on the contour of the pattern 6, sewing line matching information about the matching relationship between the sewing line 1 232 and the sewing line 2 230 can be generated. By receiving the sewing line information, the simulation apparatus can store the sewing line matching information.

The simulation apparatus according to an embodiment may generate a plurality of guide lines connecting matched sewing lines based on the sewing line matching information. For example, the simulation apparatus may generate the guide line 231 based on the sewing line matching information between the sewing line 1 232 and the sewing line 2 230. In this case, there may be a plurality of guide lines 231. In another example, the simulation apparatus may generate the guide line 251 based on sewing line matching information between the sewing line 3250 and the sewing line 4 252.

The simulation apparatus according to an embodiment may differently set at least one of the color and transparency of each sewing line. For example, the simulation apparatus may differently set at least one of the colors and the transparencies of the sewing lines 1 and 2 232 and the sewing lines 3 and 4 252. For example, when the simulation apparatus sets the colors of the sewing lines 1 and 2 232 and 230 to yellow, the colors of the sewing lines 3250 and 4 252 may be set to red. By this, the simulation apparatus can differently visualize sewing threads that do not match each other. Thus, the user can easily distinguish different sewing threads on the same pattern contour.

The simulation apparatus according to an embodiment may set at least one of a color and a transparency of the matching sewing line and a guide line connecting between the matching sewing lines to be the same. For example, the simulation apparatus may set at least one of the color and transparency of the sewing line 1 and the sewing line 2 232 and 230 matched with each other to be the same. In another example, the simulation apparatus may set at least one of the color and transparency of the sewing line 231 to be the same as at least one of the color and transparency of the sewing line 1 and the sewing line 2 230 as the matched sewing line. Similarly, the simulation apparatus may set at least one of the color and transparency of the sewing thread 3, the guide line 251, and the sewing thread 4 252 to be the same.

Figure 2b shows the sewing lines displayed when a T-shirt panel is selected at a first depth level. The avatar shown in fig. 2b may or may not be displayed in the 3D simulation. If no body part is displayed, only the design item (e.g., a cut piece or a pattern) can be displayed. The simulation apparatus 600 may determine the depth level by receiving an input selecting a visual depth. The depth level may include at least one of a level displaying the entire garment, a level displaying the cut pieces, and a level displaying the pattern. By way of example and not limitation, the level of sewing thread included in a selected panel may be displayed by activating the panel may be a first depth level.

The first depth level may correspond to a level at which the 3D garment may be modified as a whole. A tile may be displayed on a screen in response to the first depth level. If the currently displayed depth level is a "first depth level," a tile may be displayed on the screen. In a first depth level, a user interface for modifying a tile selected by a user in a 3D garment may be visualized. For example, assume that a 3D garment displayed on a screen includes two panels of a top garment and a bottom garment, and a user selects the top panel. The simulation apparatus 600 may visualize a user interface that may modify the selected upper garment panel as a whole and may transparentize or translucency the unselected lower garment panel.

As shown in fig. 2b, the following may exist: i.e. the T-shirt panel is selected as a top in the level 201 displaying the entire garment. By way of example, but not limitation, simulation apparatus 600 may receive an input selecting a first depth level. In addition, the simulation apparatus 600 may receive an input selecting one of at least one of the parts included in the garment. The simulation apparatus 600 may display sewing lines included in the selected panel at the first depth level 202. By way of example and not limitation, in response to the first depth level 202, the simulation apparatus 600 may display all sewing lines connecting patterns included in the T-shirt panels. The detailed sewing lines displayed at the first depth level 202 may be displayed as shown in fig. 2 a.

Fig. 3a shows a sleeve pattern 310,

sewing threads

330, 332 associated with the sleeve pattern 310 of the selected pattern, a guide line 331, a front body pattern 350, a back body pattern 370 and a collar pattern 390.

The simulation apparatus according to an embodiment can increase the distance between the selected pattern and the plurality of patterns adjacent to the selected pattern. For example, the selected pattern may be a sleeve pattern 310. The pattern adjacent to the sleeve pattern 320 may be a pattern attached to the sleeve pattern 310 by sewing or having a relatively close distance. For example, patterns adjacent to the sleeve patterns 310 may be collar patterns 390, front body patterns 350, and back body patterns 370. The simulator may increase the distance between the sleeve pattern 310, which is a selected pattern, and the collar pattern 370, the front body pattern 350, and/or the back body pattern 370, which is an adjacent pattern. By this, the simulation apparatus can visualize a design item (e.g., T-shirt in fig. 3 a) through the 3D exploded view so that the user can stably edit the sewing lines related to the pattern determined as the editing target.

Fig. 3b shows the sewing lines displayed when a pattern included in a panel is selected at the second depth level. The avatar shown in fig. 3B may or may not be displayed in the 3D simulation. When the avatar is not displayed, only the design item (e.g., a cut-out or a pattern) can be displayed. The simulation apparatus 600 may determine the depth level by receiving an input selecting a visual depth. The depth level may include at least one of a level showing the entire garment, a level showing a cut piece, and a level showing a pattern. For example, and without limitation, the level of sewing thread activated to display that is included in the selected pattern may be a second depth level.

The second depth level may correspond to a level at which the details of the 3D garment may be modified. The pattern may be displayed on the screen in response to the second depth level. The second depth level may allow for modification of the pattern included in the chassis. The simulation apparatus 600 may visualize the user interface for modification for the pattern selected by the user and may not visualize the user interface for the 2D patterns not selected by the user.

As shown in fig. 3b, the following may exist: i.e. the pattern included in the T-shirt panel as a jacket is selected in the level 301 displaying the entire garment. By way of example and not limitation, simulation apparatus 600 may receive an input selecting a second depth level. Further, the simulation apparatus 600 may receive an input selecting at least one pattern from patterns included in the T-shirt chassis. In response to the second depth level 302, the simulation apparatus 600 may display the sewing lines associated with the selected pattern.

Although fig. 3b shows a state in which the distance between all patterns included in the T-shirt chassis is increased, by way of example and not limitation, all other patterns except the selected pattern are in a sewn state, and only the selected pattern may be output on the screen in a state away from the other patterns. As shown in fig. 3a, detailed sewing lines displayed at the second depth level 302 may be displayed.

When the number of the sewing threads matched with the sewing threads of the pattern is two or more, the simulation apparatus according to an embodiment may receive the selection of the sewing threads of the pattern and at least one pair of the sewing threads matched with the two or more sewing threads of the pattern in the 3D exploded view.

According to an embodiment, there may be situations where more than two sewing threads match one sewing thread. For example, the sewing line 1 420 may be matched with the sewing line 2440 and the sewing line 3 460. The sewing line 1 420 and the sewing line 2440 may be matched to each other, and the sewing line 1 420 and the sewing line 3 460 may be matched to each other. In this case, in the 3D garment simulation, the sewing line 1 420, the sewing line 2440, and the sewing line 3 460 may overlap each other as one line. In this case, the pattern 1 410, the pattern 2 430, and the pattern 3 450 may be patterns connected by a line. When more than two sewing threads are matched to a single sewing thread, the user may need to individually select each sewing thread to modify the sewing thread. For example, the matching relationship between the sewing line 1 420 and the sewing line 2440 may be desired by the user, but the matching relationship between the sewing line 1 420 and the sewing line 3 460 may not be desired by the user. In this case, the user may need to select the sewing line 3 460 and modify the sewing line 3 460.

The simulation apparatus according to an embodiment may allow a user to individually select each of the sewing lines 1, 2440, and 3 460 to stably edit the sewing lines.

In the 3D exploded view, pattern 1 510 may correspond to pattern 1 410 of the 2D pattern, pattern 2 530 may correspond to pattern 2 430 of the 2D pattern, and pattern 3 550 may correspond to pattern 3 450 of the 2D pattern. Further, in the 3D exploded view, the sewing line 1 520 may correspond to the sewing line 1 420 in the 2D view, the sewing line 2 540 may correspond to the sewing line 2440 in the 2D view, and the sewing line 3 560 may correspond to the sewing line 3 460 in the 2D view.

The simulation apparatus according to an embodiment can be visualized in a 3D exploded view to allow a user to easily determine whether or not there are more than 2 sewing lines matching with the sewing lines of the pattern. For example, since the sewing line 1 520 and the sewing line 2 540 are in a matching relationship, a plurality of guide lines 570 may be displayed between the sewing line 1 520 and the sewing line 2 550. Further, since the sewing thread 1 520 and the sewing thread 3 560 are in a matching relationship, a plurality of guide lines 580 may be displayed between the sewing thread 1 520 and the sewing thread 3 560. Since the guide line is generated based on the sewing line matching information, the simulation apparatus can be visualized through the 3D exploded view to allow the user to easily determine whether one sewing line matches more than two sewing lines. Since the matched sewing lines cannot overlap each other in the 3D exploded view, the user can accurately determine whether the matched sewing lines are 2 or more and select each pair of matched sewing lines. Thus, the user can select and modify pairs of two or more sewing threads.

When the number of the sewing lines matched with the sewing lines of the pattern is two or more, the simulation apparatus according to an embodiment may receive a selection of the guide lines connecting the two or more sewing lines matched with the sewing lines of the pattern in the 3D exploded view. For example, since the sewing line 1 520 and the sewing line 2 540 are in a matching relationship, a plurality of guide lines 570 may be displayed between the sewing line 1 510 and the sewing line 2 540. In addition, since the sewing line 1 520 and the sewing line 3 560 are in a matching relationship, a plurality of guide lines 580 may be displayed between the sewing line 1 510 and the sewing line 3 560. The simulation device may receive input from the user selecting guide line 570 or guide line 588. If a guide line is selected, a pair of sewing threads connected to the guide line may also be selected.

The simulation apparatus according to an embodiment may delete the selected guideline based on a selection input of the user. The user may enter into the electronic device to delete the selected guideline. For example, when an input to select the guide line 570 is received and an input to delete the guide line 572 is received, the simulation device may delete the selected guide line 577. The simulation apparatus according to an embodiment may delete the selected guide line and delete the matching relationship between the sewing lines connected by the selected guide line. For example, the simulation device may delete the matching relationship between the

sewing lines

520, 540 connected by the selected guide line 570.

The style line may be a line having a function of changing a style of the 3D garment. The style line may be a line inside the pattern, and the user may arbitrarily generate on the pattern. Under certain conditions, style lines can be generated on the pattern. The style line may be generated based on a line or a point on the pattern. The starting and ending points of the style line may be lines or points on the pattern. When the pattern line is generated on the pattern, the pattern can be automatically divided along the pattern line inside the pattern, and a pair of sewing lines can be generated along the pattern line.

The user may generate style lines on the pattern to change the style of the 3D garment. For example, if the style line is generated on the pattern, the pattern may be divided into two patterns based on the style line, and the sewing line and the guide line may be generated in each divided pattern according to the style line. Therefore, there may be sewing threads in the outline of the divided pattern, and connecting the sewing threads may become style threads.

The simulation apparatus according to an embodiment may generate a style line for changing a style of the 3D garment on the pattern based on a selection input of the user. The selection input by the user may be an input to generate a style line on the pattern. In the screen 1 700, the user can input a style line on a pattern. In the screen 2 701, the style line 710 generated on the pattern 720 is displayed.

The simulation apparatus according to an embodiment may generate the first sewing line, the second sewing line, and the guide line based on the style line.

Referring to fig. 6, as shown in screen 3 702, a pattern 720 may be divided into a first pattern 721 and a second pattern 722. The first sewing line 711 may be positioned on the contour of the first pattern 722. The second sewing line 712 may be positioned on the contour of the second pattern 712. The first sewing line 711 and the second sewing line 712 may be in a matching relationship. In addition, the simulation apparatus may display a guide line 713 connecting the first sewing line 711 and the second sewing line 712.

The simulation apparatus according to an embodiment may edit at least one of the first sewing line 711 or the second sewing line 712. The user may input a length modification of the first sewing thread 711 or a length modification of the second sewing thread 712 to the electronic device. For example, the user may adjust the length of the first sewing line 711 by adjusting the position of the point 1 730 (as the end point of the first sewing line). Referring to fig. 6, as shown in screen 4 703, the position of point 1 730 may be moved to the position of point 1 731. Similarly, as shown in screen 4 703, the position of point 2 740 may be moved to the position of point 2 741. As the length of the sewing thread is modified, the guide line connecting the sewing thread may be modified and displayed. Accordingly, the simulation apparatus may determine the modified length of the first sewing line or the modified length of the second sewing line based on the selection input of the user. Further, the simulation device may modify the guide line based on at least one of the modified length of the first sewing line or the modified length of the second sewing line. As a result, the sewing lengths of the two patterns are different, and thus various changes can be made to the appearance of the designed article in the 3D garment simulation.

Fig. 7 is a block diagram illustrating a simulation device according to various embodiments.

The simulation apparatus 600 according to an embodiment may be a server or a terminal. The simulation device according to various embodiments described herein may be one of various types of devices. The simulation apparatus may include, for example, a portable communication apparatus (e.g., a smartphone), a computer device, a portable computing apparatus, a camera, a wearable device, or a tablet device. Referring to fig. 7, a simulation device 600 according to an embodiment may include a user interface 610, a processor 630, a display 650, and a memory 670. The user interface 610, processor 630, display 650 and memory 670 may be connected to each other by a communication bus 605.

Visual depth may refer to a garment (e.g., cut pieces, patterns) output on a screen where a user modifies the garment. Therefore, the degree of visualization of the garment output on the screen can be changed according to the change of the visual depth. The visual depth may include a plurality of depth levels. According to an embodiment, by allowing a user to select a depth level for modification among depth levels for hierarchically displaying a cut piece included in a 3D garment and a pattern constituting each cut piece in a 3D exploded view (e.g., a 3D garment on which a wearing simulation is completed on its part), an object to be modified can be clearly separated from other objects to be modified for visualization and/or modification even if a plurality of modifiable objects are intricately entangled together in a 3D simulation space.

According to an exemplary embodiment, by setting the operation mode of the simulation apparatus to a working mode for performing an editing function that can be performed for each depth level and a moving mode for switching the depth levels, it is possible to stably perform movement between the depth levels and operation at the moved depth levels.

The user interface 610 may receive a user input for selecting any one of a plurality of objects corresponding to a depth level next to a currently displayed depth level among depth levels for hierarchically displaying one or more cut pieces included in a 3D garment whose wearing simulation is completed on its body and a pattern (2D pattern) constituting each cut piece. For example, the user interface 610 may receive user input on 3D clothing, parts, and/or patterns displayed in 3D space via a stylus, mouse click, and/or touch input by a user's finger, among other things.

Further, the user interface 610 may receive user input for a remaining empty space other than the plurality of objects in the simulation space in which the plurality of objects are displayed.

Processor 630 may activate and visualize the selected panels and/or patterns. Further, the processor 630 may deactivate at least one remaining tile and/or pattern other than the selected tile and/or pattern for transparent or semi-transparent visualization.

For example, when the next depth level is a first level displaying tiles, the processor 630 may activate and visualize any of the tiles selected in response to the first level; when the next depth level is the second level at which the pattern is displayed, processor 630 may activate and visualize the pattern selected in response to the second level. In this case, when the selected pattern is covered by other unselected 2D patterns, the processor 630 may clearly visualize the selected 2D pattern through the other 2D patterns.

For example, when the user interface 610 receives user input for a remaining white space other than a plurality of objects in the simulation space, the processor 630 may not display a next depth level in response to the user input for the white space and maintain a currently displayed depth level.

Display 650 displays the 3D exploded view generated by processor 630.

The memory 670 may store the generated 3D exploded view, sewing line information, and the like. In addition, the memory 670 may store various information generated during the processes performed by the processor 630. In addition, the memory 670 may store other various data and programs, and the like. Memory 670 may include volatile or non-volatile memory. The memory 670 may include a mass storage medium such as a hard disk or the like and stores various data.

For example, the simulation apparatus 600 implemented by hardware may include a microprocessor (micro processor), a Central Processing Unit (Central Processing Unit), a processor core (processor core), a multi-core processor (multi-core processor), a multiprocessor (multi processor), an Application Specific Integrated Circuits (ASICS), a Field Programmable Gate Array (FPGA), and the like.

The processor 630 may execute a program and control the simulation apparatus 600. Program code executed by processor 630 may be stored in memory 670.

The method according to the embodiment is embodied in the form of program commands that can be executed by various computer means and recorded in a computer-readable medium. The computer readable and writable medium may include program commands, data files, data structures, etc. alone or in combination. The program instructions recorded on the medium can be instructions specially designed and constructed for implementing the embodiments, or instructions commonly used by those skilled in the computer software art based on the common usage.

To perform the operations of the embodiments, the hardware devices may be configured in such a way that the operations are implemented in more than one software module, and vice versa.

The software may include a computer program (computer program), code, instructions (instructions), or a combination of one or more thereof, that enables the processing device to operate as desired, or to command the processing device individually or collectively.
