The purpose of the present invention is to allow a user, when folding a pattern during a 3D garment draping simulation, to input an angle as if the user folds the pattern with hands in a 3D space rather than inputting the angle as an attribute value. According to an aspect of the present invention, a method for a 3D garment draping simulation comprises the steps of: setting a folding line disposed on a pattern; receiving an angle between opposite sides of the pattern, divided by the folding line, and setting any one of the opposite sides of the pattern as a pattern for folding; and performing folding on the pattern based on the received angle.

Description

TECHNICAL FIELD [0001] The present invention relates to a method and a device for simulating 3D clothing,

Relates to a computer simulation technique, and more particularly, to a draping simulation technique for colliding 2D clothing patterns on an avatar.

Currently, costume simulation technology is used not only in the fashion industry, but also in games, animation, film special effects, and so on. In addition, the market size of the costume item sales in the virtual world amounts to several trillion won.

Open Publication No. 10-2014-0108451 discloses a method of draping clothes on a 3D avatar as a process of 3D upside-down simulation. In the process of placing a 2D pattern around an avatar and sewing it to create an outfit on the avatar, the pattern may dive into the interior of the avatar and cause the intersection of the pattern and the avatar. In order to eliminate such an intersection, in the draping method, a cross-cut mesh is searched for the intersection between the pattern and the avatar, and when there is a cross-over mesh, the intersection removal force And a crossover removal force of the generated predetermined size is applied to the mesh to eliminate the intersection.

This 3D clothing simulation simulation method can change the attributes of the mesh that forms a part of the 2D pattern to express the detail of the garment. For example, after sewing two fabrics, you can set them to maintain a constant angle at the boundary between the two fabrics. However, this process is mainly performed by inputting the angle value in the property window.

In the existing 3D costume making process, the method of folding the pattern is done by inputting the angle value as the property value of the seam line. However, this method is inconvenient because it is difficult to convey a feeling that the pattern is folded by hand, and it is necessary to input an angle value several times in order to express fine detail, and to check the output every time.

The present invention provides a user interface tool capable of folding a pattern on a 3D screen.

The present invention aims at providing a folding line and a 3D folding guide line and allowing a user to set the angle at which the pattern folds on 3D by dragging the 3D folding guide line.

According to an aspect of the present invention, there is provided a method for simulating a 3D dressing method, the method comprising: designating a folding line on a pattern; inputting an angle formed by both patterns distinguished by a boundary of the folding line, And folding the pattern according to the input angle.

In one aspect, the step of folding the pattern may be such that folding of either pattern, which is distinguished by the folding line boundary, is processed independently of the other to form the input angle.

In one aspect, the method further comprises extracting inner segments and seams of the pattern disposed or draped around the 3D avatar prior to the step of specifying the folding line.

In one aspect, the step of folding a pattern may be performed such that meshes having a folding line as a common line segment among the meshes forming a pattern are formed at angles that are input, and the motions of the remaining meshes excluding the meshes are calculated, .

In one aspect, an angle formed by both patterns distinguished from each other by the folding line is input from a user, and the step of individually inputting both patterns generates a 3D folding guide that guides the pattern to fold the folding line on the axis And then receiving a rotation of the 3D folding guide line from the user about the folding line.

In an aspect, the 3D folding guide includes bidirectional guides to guide the two patterns, each distinctively bounded by the folding line.

According to an aspect of the present invention, the step of folding the pattern may be performed such that the meshes meeting the 3D folding guide line among the meshes having the folding line as a common line segment form the input angle, and move the remaining meshes except the corresponding mesh, Calculating and folding together.

  In one aspect of the present invention, the step of calculating the movement reflecting the physical properties of the pattern and performing the folding process includes a step of calculating a distance between the mesh including the compression spring and the 3D folding guide line .

In one aspect, the method further includes generating a visual motion image of a pattern to be dragged together according to the drag of the 3D folding guide line, and outputting the generated visual motion image to the screen.

In one aspect, the 3D wrapping simulation apparatus includes a folding line designation unit for designating a folding line on a pattern, an angle formed by both patterns distinguished from a fold line by a user, And a folding processor for folding the pattern according to the input angle.

In 3D costume making process, when expressing the details of costume, it is possible to convey the feeling of being expressed by the hand in the real world to the user, making the costume production easier. Specifically, it is convenient to express the folded state of the collar or the sleeves of the 3D clothes, thereby shortening the time for producing the clothes.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The 3D costume is created through a computer simulation program that reflects the process of creating the actual costume. For example, the author paints a 2D pattern of a costume, then drapes and simulates a 2D pattern on an avatar model to be dressed. By rendering and displaying the draping simulation result, the 3D image is displayed on the screen. The avatar model and the 2D costume pattern can be drawn directly by the user through a computer program or can be stored. If you draw yourself, you can enter it using a variety of graphics software or CAD programs, or use the provided 2D patterning tools.

The draping simulation method in the 3D dress-up simulation method according to an embodiment includes a mesh patterning step of 2D pattern, a step of disposing a pattern around the avatar, applying a force to pull the pattern along the set seam, Calculating a deformation of a mesh according to a collision removing force, and performing a draping simulation to calculate a deformation of a mesh according to a collision removing force, . The 2D mesh patterning step may be performed by applying a Delaunay triangulation technique. The draping simulation process may be performed as an example (Pascal Volino, Nadia Magnenat Thalmann: Resolving surface collisions through intersection contour minimization.ACM Trans. Graph. 25 (3): 1154-1159 (2006).

FIG. 1 is a flowchart illustrating a method of folding a pattern from a folding line to a boundary on a 3D screen in a 3D dressup simulation method according to an exemplary embodiment.

A method of 3D 3D dressing simulation according to an aspect of the present invention includes a step of designating a folding line (Folding Line) 40 on a pattern, an angle formed by both patterns separated by a boundary of the folding line 40, (S02) of inputting any one of the patterns into the folding pattern, and folding the pattern according to the input angle (S03).

In an aspect, the folding line 40 is designated on the pattern (S01). The pattern is created by setting the appearance and physical properties of the fabric. The interior of the pattern can be composed of triangular or square meshes. A mesh can consist of a lattice point having a mass and a spring connecting the lattice point. Each spring constitutes a branch connecting the grid points 10 and 20 at the edges of the polygon. Through lattice points and springs, properties such as the nature of the pattern material, the folding of the fabric, and stretching can be simulated.

In one embodiment, the folding line 40 may direct a user to draw a straight line, a curve, or a graphic form on a pattern of the 3D screen. When drawing the folding line 40, a mouse or a touch pen can be used. As will be described later, the folding line 40 may be designated by selecting the extracted specific line.

In one embodiment, the pattern may be a pattern placed on the 3D avatar prior to draping, or it may be a pattern draped on the 3D avatar.

In one embodiment, once the folding line 40 is designated, the meshes that make up the pattern are reconstructed such that a banding wing is formed along the folding line 40. Two meshes having one common fold line 40 as a branch line are defined as a banding wing. 2 is an embodiment of a banding wing having a predetermined angle. In one embodiment, a banding wing is connected to two vertexes 10 and 20 of a banding wing, as shown in FIG. 2, to define an object 30 that maintains an angle formed by the two meshes . In one embodiment, the object described above may be a compression spring 30 having a predetermined restoring force. However, the above-described object 30 can be used to calculate the force that makes the angle of the banding wing, but does not appear on the screen when simulating and displaying the 3D image.

FIG. 3 is a diagram showing a reconstruction of meshes such that a banding wing is formed along the folding line 40. In the banding wing formed along the folding line 40 according to an embodiment, the common branches of two adjacent meshes are connected to constitute the folding line 40.

In an aspect, when the folding line 40 is designated, the user may receive an angle formed by both patterns distinguished by the folding line from the user, and inputting any one of the patterns as a folding pattern S02). In one embodiment, when the folding line 40 is designated, the user can select any one of the patterns that are distinguished by the folding line 40. [ Thereafter, the angle formed by the two patterns with respect to the selected pattern can be inputted numerically, or the desired angle can be inputted through the movement of the selected pattern by operating the direction key of the keyboard. In another embodiment, when the folding line 40 is designated, the user inputs an angle formed by the two patterns distinguished by the boundary of the folding line 40, and then selects any one of the patterns to be folded You can specify a pattern. In this case, enter the angle in numerical values. As will be described later, even if any of the two patterns distinguished by the folding line 40 is selected and the angle is input, the angle formed by the two patterns is the same, but the pattern for moving the input angle is different. In one embodiment, the 3D folding guide line 50 may be displayed on the screen and the angle may be input by dragging the pattern within the 3D screen. Details of this will be described later.

In an aspect, when the user inputs an angle formed by both patterns distinguished by the folding line 40, the pattern is folded according to the input angle (S03). In one embodiment, when the pattern is folded, the angles formed by both patterns about the folding line 40 are formed at the input angle. That is, both patterns are folded to form the input angle. At this time, the pattern that is moved to be in the folded state is any one of the patterns that are distinguished by the folding line 40 and that are selected by the user when the angle is input. 5 is an embodiment showing a collar shape of a 3D garment before and after the folding process. In FIG. 5, both patterns distinguished by the folding line 40 are shown as a first pattern 53-1 and a second pattern 53-2. According to the embodiment of FIG. 5, in the first pattern 53-1 and the second pattern 53-2, which are distinguished around the folding line 40, the first pattern 53-1 is folded in the form of a collar First, the first pattern 53-1 is selected. Thereafter, an angle to be formed by the first pattern 53-1 and the second pattern 53-2 is input. As a result, only the first pattern 53-1 is moved as shown in FIG. 5B so that the first pattern 53-1 and the second pattern 53-2 form an input angle.

In a specific aspect, folding of any one of the two patterns, which are distinguished by the folding line 40 in the pattern folding process, may be processed independently of the other to achieve the input angle. As described above, when any one of the two patterns distinguished by the boundary of the folding line 40 is selected and the angle is input, only the corresponding pattern is folded. At this time, the movement has no effect on the other pattern . For example, the folding of any one of the first pattern 53-1 or the second pattern 53-2 may be processed independently of the other pattern to form a predetermined angle. 5, when the first pattern 53-1 is folded, the second pattern 53-2 connected to the first pattern 53-1 and the folding line 40 is connected to the first pattern 53-1, 1) without being influenced by the folding process. As another example, in FIG. 6, when the first pattern is folded, the second pattern portion remains unchanged.

In a further aspect, the method may further comprise extracting inner segments and seams of the pattern disposed or draped around the 3D avatar prior to the folding line 40 designation step. When the user executes the 3D folding function, the inner line segment and the seam line of the pattern in the 3D screen are extracted and displayed as a highlight. The user can select a line to be designated as the folding line 40 among the lines indicated by the highlight. At this time, a plurality of lines can be selected. The line selected as described above is designated as folding line 40.

In one aspect, the meshes having the common line segment of the folding line 40 among the meshes forming the pattern are formed at the set angle, and the motions of the remaining meshes other than the meshes may be calculated and folded together. Among the meshes forming the pattern, the meshes having the folding line 40 as a common line segment refer to the banding wings formed when the folding line 40 is designated as described above. Therefore, when the user inputs an angle, the angle is applied to the angle formed by the banding wings. At this time, only the banding wings are folded by applying the angle, but the remaining meshes other than the banding wings constituting the pattern are folded. In one specific embodiment, the folding process of the remaining meshes other than the banding wing may be accomplished by calculating a motion that can maintain the original connection with the banding wing. For example, if the remaining meshes connected to the banding wing were parallel to the banding wing, they would move with the banding wing while maintaining the parallelism. As another example, if the remaining meshes connected to the banding wing are connected to the banding wing in a rugged manner and the pattern is curved, the movement that can maintain the state is calculated and folded. 6 is an embodiment showing a side cross-sectional view of the pattern when the banding wing and other meshes are folded together. It is shown through the side cross-section of the pattern that the folded pattern maintains the pattern state before folding. In FIG. 7, if the folding process of folding up the left pattern with respect to the folding line 40 with respect to the pattern is performed, the portion corresponding to the right pattern with respect to the folding line 40 is maintained as it is before the folding process Respectively.

In a specific aspect, an angle formed by both patterns distinguished by the boundary of the folding line 40 from the user is input, and the step of selecting one of the patterns as a pattern to be folded includes the step of: Creating a 3D folding guide line 50 that guides the folding line 50 to guide the folding line 40 and then inputting the rotation of the 3D folding guide line 50 along the folding line 40 from the user.

In one embodiment, the 3D folding guide 50 refers to a leader that guides the angle at which the pattern is folded to be received from the user on the 3D screen. FIG. 3 illustrates one embodiment of such a 3D folding guide line 50. FIG. The 3D folding guide line 50 includes a first guide line 51 which is a circle for visually confirming the change of the angle to be inputted and a second guide line 51 which is a second guide line 51 perpendicular to the folding line 40 on the pattern to be folded. And a guide line 52. In one embodiment, the first guide line 51 is a circle having the diameter or radius of the second guide line 52. The second guide line 52 may be replaced with a line segment capable of guiding an angle, a dotted line, etc. in addition to the arrows. In one embodiment, the 3D folding guide line 50 allows the user to click on a point 60 on the folding line 40 to move the point 60 to the center point 60 of the first guide (circle) And the second guide line (52). 4 is a view showing a state in which a second guide line 52 is generated in a folding wing folded along a folding line 40. In FIG. 4 (a) is an embodiment of a banding wing in which a second guide line 52 is shown, and FIG. 4 (b) is a sectional view of FIG. As shown in FIG. 4, the second guide line 52 is generated as if it is placed on the pattern guided by the guide line. For example, when the user selects a point on the folding line 40, the second guide line 52 is moved in parallel with the mesh surface of the banding wing, . At this time, the folding line 40 and the second guide line 52 are perpendicular to each other as described above.

In an aspect, the user may make an input that the 3D folding guide 50 rotates about the folding line 40. Here, the rotating guide line refers to the second guide line 52 described above. In one embodiment, the rotating input may be to drag the second guide line 52 on the 3D screen, or may be to rotate the second guide line 52 slightly at regular intervals using a keyboard directional key. In one embodiment, when the user makes an input to rotate the second guide line 52, the second guide line 52 is rotated about the folding line 40 along the first guide line 51 made of a circle, The second guide line 52 can be folded to form a desired angle. As will be described later, the angle of folding of the second guide line 52 is set to an angle at which the pattern is folded, and the angle at which the pattern is folded is an angle formed at the banding wing, which is two meshes with the common fold line 40 as a common line segment. .

As described above, the step of receiving the rotation of the 3D folding guide line 50 may include dragging the second guide line 52 of the 3D folding guide line 50 or rotating the second folding line 52 at a predetermined interval It can be done. In a specific embodiment, when a user inputs a certain angle by dragging and rotating the second guide line 52 of the 3D folding guide line 50, the pattern guided by the second guide line 52 is guided by the second guide line 52 Is folded at a predetermined angle. That is, since the pattern is placed in parallel with the second guide line 52, both patterns separated by the boundary of the folding line 40 form a certain angle. 5 is an embodiment showing the shape of the collar of the 3D garment before and after the folding process according to the drag of the second guide line 52. FIG. According to the embodiment of FIG. 5, in the first pattern 53-1 and the second pattern 53-2, which are distinguished around the folding line 40, the first pattern 53-1 is folded in the form of a collar And inputs a drag to rotate the second guide line 52-1 so that the second guide line 52-1 faces in the opposite direction. In this case, the angle formed by the first pattern 53-1 and the second pattern 53-2 is the angle formed by the first pattern 53-1 so that the angle of the second guide line 52-1 is changed according to the drag input, Is moved and folded. That is, folding processing is performed as shown in FIG. 5 (a) to FIG. 5 (b).

In one aspect, the 3D folding guide 50 is configured to guide the folding line 40 in both directions 52-1, 52-2 and 52-3 to guide the first pattern 53-1 and the second pattern 53-2, respectively, -2). ≪ / RTI > 3 and 5 show a 3D folding guide line 50 including bidirectional guides 52-1 and 52-2. The bi-directional guides 52-1 and 52-2 refer to the 3D folding guide line 50, which is an independent object configured to guide the second guide lines on both sides of the folding line 40, respectively. In one embodiment, the two guide lines 52-1 and 52-2 of the first guide line 51, the second guide line 52 and the second guide line are displayed in different colors, .

In a further aspect, the step of folding the pattern may be performed such that the meshes meeting the 3D folding guide line 50 among the meshes having the folding line 40 as a common line segment form the set angle, Calculating a motion reflecting the physical properties and folding the motion together. This step can be briefly referred to as a folding process step that reflects the physical properties of the pattern. In one embodiment, the mesh that meets the 3D folding guide line 50 refers to the mesh that meets the second guide line 52 of the 3D folding guide line 50.

The physical properties of a pattern refer to the physical properties of the meshes forming the pattern. As described above, the meshes are composed of lattice points having masses and springs connecting lattice points. Each spring constitutes a branch connecting the grid points 10 and 20 at the edges of the polygon. The mass of the lattice point and the modulus of elasticity of the spring are typical examples of the physical properties of the mesh. Through the physical properties of the mesh, the properties of the pattern material, the folding of the fabric, and the slackness can be simulated.

FIG. 8 shows an embodiment in which the pattern is folded by reflecting the physical properties. In one embodiment, when the physical properties of the pattern are reflected in the folding process, the banding wings having one common folding line 40 may have different angles. For example, when the 3D folding guide line 50 receives a predetermined angle, the folding wing including the center of the second guide line 52 of the 3D folding guide line 50 is folded to form the predetermined angle , And the remaining banding wings can be calculated considering the relationship between the physical properties of the pattern and the movement of the reference banding wing.

The folding process step of reflecting the physical properties of the pattern is performed by moving the coefficient value of the compression spring 30 of the mesh having the folding line 40 as a common line segment to the mesh including the compression spring 30 and the 3D folding guide line 50 in accordance with the distance from the target. According to one embodiment, when the angle is inputted by dragging the 3D folding guide line 50, the banding wing having the folding line 40 as a common branch is folded at an appropriate angle. At this time, the compression spring 30 of the banding wing And the force to maintain. The force is proportional to the coefficient value of the compression spring 30 included in the banding wing. In one embodiment, the force that maintains the input angle of the banding wing is greater for the banding wings closer to the second guide line 52 that received the folding input, and the banding wings located farther away from the second guide line 52, Lt; RTI ID = 0.0 > force. ≪ / RTI > That is, the extent to which the force for maintaining the angle of the banding wing varies depending on the distance from the second inner ring line 52 varies depending on the distance between the banding wing and the second guide line 52, Depending on what you do. As a result of the reflection of the physical properties, the banding wing located closer to the 3D folding guide line 50 is folded closer to the input angle, and the angle of the banding wing located farther from the 3D folding guide line 50 becomes larger have. In one embodiment, the folding process of the pattern reflecting the physical properties includes calculating a force to maintain the folding angle in each banding wing, and calculating the force applied to the meshes forming the pattern and the movement thereof can do. For example, the force applied to the mesh and the resulting movement can be calculated in turn starting from the banding wings, and then sequentially from the nearest meshes connected to the banding wings to the meshes far away. As an example of folding the pattern by reflecting the physical properties, in FIG. 8, the second guide line 52 is located in the vicinity of the center, and the folding process shows a state in which the edge is folded less near the center. The 3D folding guide line 50 may be applied to a case where the 3D folding guide line 50 is rotated using a keyboard direction key or a direction key provided on the screen.

9 is a view illustrating a process of folding pants draped on a 3D avatar. The folding line 40 is designated to fold the bottom of the pants and the 3D folding guide line 50 is dragged to fold the pattern of the bottom of the pants as shown in the second figure of FIG. When the physical properties are reflected at the folding process, the pattern shape is deformed as shown in the second figure of FIG. 9, unlike the case where the pattern is not folded while maintaining the shape before the pattern is folded.

In one aspect, a visual motion image of a pattern to be dragged together according to the drag of the 3D folding guide line 50 can be generated and output to the screen. In one embodiment, when a user drags the 3D folding guide line 50, a dragging of the guide line and a pattern guided by the guide line are dragged together. Accordingly, it is possible to provide details of a pattern on a 3D screen by providing a visual motion image such as a pattern of a user dragging and folding the pattern.
