Description

SYSTEM AND METHOD FOR COMBINING CHARACTER CAT ITEM

The present invention relates to a character costume item combining system and method for combining a hat item with a character.

In recent years, online games using 3D virtual space have been developed. When the online game is executed, the animation character for substituting the user in the 3D virtual space can be set or stored.

Conventionally, an animation character can be set by a method in which a user selects one of several fixed characters provided by an online game program. However, when combining costume items with characters in a 3D virtual space, it is difficult to obtain the same result as a person wearing a costume.

Particularly, when a hat item is combined with a character, it is difficult to deform the hair portion of the character to fit the size or shape of the hat item, so that a natural combination result such as wearing a hat can not be obtained. Therefore, when a character and a hat item are combined, a specialist must manually modify the hat item on the character's hair part by hand. For example, if you combine five hat items for the same character each, or if you combine one hat item with a character that has different hair parts (i.e., hairstyle), then the expert must go through five modifications Work time and work costs increased.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a hair styling apparatus, a hair styling apparatus, a hair styling apparatus, And to provide a system and method that can naturally combine hat items.

A method of combining a character hat item according to an embodiment of the present invention includes generating a reference bust model corresponding to a hat item, compressing the normal hair of the character to transform the pressed hair into a pressed hair, And combining the hat item with the deformed pressed hair to correspond to the reference bust model.

According to the present invention, it is possible to automatically combine a hat item with a character by modifying the normal hair of a character into a pressed hair, and modifying the pressed hair to correspond to a reference bust model corresponding to the hat item. Accordingly, it is possible to reduce the working time and the operation cost required for combining the hat item with the hair portion of the character, and it is possible to naturally combine the hat item with the hair portion of the character.

1 is a block diagram illustrating a configuration of a character hat item combination system according to an embodiment of the present invention. The character hat item combining system 100 shown in FIG. 1 (hereinafter, referred to as a 'system') can provide a user interface for item setting. When a hat item for a character in the 3D virtual space is set on the user interface , And performs a processing operation for combining the hat item with the hair portion of the character.

Referring to FIG. 1, the system 100 includes a model generating unit 110, a first hair deforming unit 120, a second hair deforming unit 130, and an item combining unit 140.

The model generation unit 110 generates a reference bust model corresponding to the predetermined hat item. Specifically, the model generation unit 110 generates a mesh of the reference bust model corresponding to the hat item.

A mesh is modeling data of an object represented by a triangle or a polygon composed of the combination of the triangles in three-dimensional modeling. The vertex means a vertex such as a triangle or a polygon constituting a mesh.

The model generation unit 110 separates the mesh of the reference bust model into the overlap region, the border region, and the non-overlap region based on the hat item. That is, a state in which the hat item is worn on the reference bust model is three-dimensionally modeled, and the mesh of the reference bust model is divided into an overlap area where the hat items overlap, a non-overlap area where the hat items do not overlap, As shown in FIG.

The model generation unit 110 sets different color weights in the overlap region, the border region, and the non-overlap region in the mesh of the reference bust model. Specifically, the color weights of the overlapping area and the border area overlapping with the hat item are set to the maximum, and the color weights of the non-overlapping area are set to be minimized as they are further away from the border area. For example, the color weights may be set in the range of 0 to 1, where the color weights of the overlap region and the border region may be set to 1, which is white, and the color weights of the non- It can be set close to zero indicating black.

The first hair deforming unit 120 compresses the normal hair of the character and deforms the pressed hair. Specifically, the first hair deformer 120 creates a virtual bust mesh and creates a center curve in the inner space of the virtual bust mesh. Then, the normal hair of the character is transformed into the pressed hair by using the virtual bust mesh, the center curve, and the mesh of the normal hair of the character.

The virtual bust mesh is a three-dimensional modeling data of the virtual bust from head to chest, and is used to transform the character's normal hair into a pressed hair. The first hair deformer 120 connects one or more shortest points between the center curve created in the inner space of the virtual bust mesh and the mesh of the character's normal hair to create one or more connecting lines. That is, one point of the center curve at the shortest distance from any one vertex included in the mesh of the normal hair of the character is detected and designated as the shortest point. This method can be applied to each vertex included in the character's normal hair's mesh to specify one or more shortest points on the center curve.

Also, one or more intersection points between the one or more connecting lines and the virtual bust mesh are connected to transform the normal hair of the character into a pressed hair. That is, one or more connecting lines pass through the virtual bust mesh, and the intersection point at this time can be generated as an intersection point. By connecting the generated intersection points, you can transform a character's normal hair into a pressed hair. In this case, the intersection point can be a vertex that constitutes the mesh of the pressed hair.

The mesh of the pressed hair is created using one or more connection lines connecting each vertex included in the mesh of the normal hair of the character, and has a topology structure corresponding one-to-one with the mesh of the character's normal hair.

The second hair deforming part 130 deforms the pressed hair to correspond to the reference bust model generated in the model generating part 110. [ Specifically, the second hair deforming part 130 deforms the deformed pressed hair in the first hair deforming part 120 to correspond to the reference bust model corresponding to the hat item. As a result, . In this case, deforming the pressed hair, not the normal hair of the character, corresponding to the reference bust model is more accurate because the mesh of the pressed hair is close to the mesh of the reference bust model in a distance.

First, the second hair deforming unit 130 detects the vertex close to the triangle among at least one vertex constituting the mesh of the pressed hair by using the barycentric coordinates of the triangle included in the mesh of the reference bust model . Then, a deformation color weight to be applied to the detected vertex is calculated using the coordinates of the center of gravity and the color weight of the triangle.

Thereafter, the second hair transformer 130 transforms the vertex detected using the coordinate of the detected vertex, the coordinate of the vertex corresponding to the detected vertex among the vertices constituting the mesh of the normal hair of the character, and the calculated deformation color weight Computes the coordinates of the new vertex to be located. That is, coordinates of a new vertex for transforming the coordinates of one or more vertices constituting the mesh of the pressed hair to correspond to the reference shape model are calculated.

The second hair deforming part 130 performs the above-described operation on all the vertices constituting the mesh of the pressed hair, thereby changing the position of the new vertex where all the vertices will be positioned . Therefore, each of the vertices constituting the mesh of the pressed hair is moved to the position of the new vertex to deform the pressed hair corresponding to the reference bust model.

The item combining unit 140 combines the pressed hair and the hat item deformed in the second hair deforming unit 130.

The character item combination system 100 shown in FIG. 1 transforms a normal hair of a character into a pressed hair, and modifies it to correspond to a reference bust model corresponding to a hat item, thereby adapting the hair portion of the character to a hat item It can be transformed into enemy. Thus, a character and a hat item can be naturally combined like an actual person wears a hat.

FIG. 2 and FIG. 3 are schematic views showing a mode in which a normal hair of a character is deformed by a pressed hair according to an embodiment of the present invention. FIG. 2 is a view for explaining a method of deforming normal hair of a character into a pressed hair, and FIG. 3 is a view showing a pressed hair obtained by deforming normal hair of a character.

Referring to FIG. 2, the system 100 includes a virtual bust mesh 210 and an imaginary bust mesh 210 that are used to transform a character's normal hair's mesh 230 into a pressed hair, To produce a center curve 220.

The system 100 transforms the normal hair of the character into a pressed hair using the mesh 230 of the normal hair of the character, the virtual bust mesh 210 and the center curve 210. In this case, the mesh 230 of the normal hair of the character is three-dimensional modeling data of the normal hair of the character.

The system 100 detects one point of the center curve 210 at the shortest distance from any one vertex included in the mesh 230 of the character's normal hair and designates the point as the shortest point. Such a method may be applied to each vertex included in the character's normal hair's mesh 230 to specify one or more shortest points on the center curve 210. Then, each vertex is connected to the corresponding shortest point to create one or more connection lines.

For example, in FIG. 2, a first shortest point 221 at the shortest distance from the first vertex 231 included in the mesh 230 of the normal hair of the character is generated in the center curve 220, The first connecting point 240 is created by connecting the vertex 231 and the first shortest point 221.

The system 100 then connects one or more intersection points between the one or more connecting lines and the virtual bust mesh 210 to transform the normal hair of the character into a pressed hair.

For example, the first connecting line 240 intersects a point of the virtual bust mesh 210, which points to the first intersection point 211. In this case, the first intersection point 311 may be one vertex that constitutes the mesh of the pressed hair. In this manner, one or more intersection points between each connecting line and the virtual bust mesh 210 are designated and each intersection point is connected. Thus, a mesh of the pressed hair can be generated. That is, the normal hair of the character can be compressed and deformed into a pressed hair.

Using the method shown in FIG. 2, the normal hair 310 of the character can be transformed into the pressed hair 320, as shown in FIG. The normal hair 310 and the pressed hair 320 of the character can be represented by a mesh, which is three-dimensional modeling data. In this case, the mesh of the pressed hair 320 is generated by one or more vertices constituting the mesh of the normal hair 310 of the character, and the topology structure corresponding one-to-one with the mesh of the normal hair 310 of the character Lt; / RTI >

FIGS. 4 and 5 are schematic diagrams illustrating a method of generating a reference bust model corresponding to a hat item according to an embodiment of the present invention. 4, the system 100 creates a hat item 410 set on the user interface for item setting and a reference bust model 420 corresponding to the hat item 410. [ This reference bust model 420 may be a bust of a mannequin in the form of a hat item 410 covered. The reference bust model 420 may be one of a plurality of reference bust models previously stored in the system 100. Specifically, the system 100 can be generated by detecting the hat item 410 among the plurality of reference bust models and the reference bust model that is most suitable.

Alternatively, a corresponding reference bust model 420 is generated in advance according to the hat item 410, and if the hat item 410 is selected on the user interface, the corresponding reference bust model 420 is generated You may.

Alternatively, if the cap item 410 is selected on the user interface, a reference bust model 420 corresponding to the cap item 410 may be generated using the three-dimensional modeling program.

4 and 5, the system 100 performs operations by expressing the hat item 410 and the reference bust model 420 as meshes, which are three-dimensional modeling data.

When the reference bust model 420 corresponding to the hat item 410 is generated, the system 100 determines whether the mesh of the reference bust model 420 is overlapped with the hat item 410 based on the hat item 410 Overlapping region B and the border region C between the overlapping region A and the non-overlapping region B, as shown in Fig. The boundary region C may be a region separated from the boundary line 421 between the overlapping region A and the non-overlapping region B by a predetermined distance in the direction of the non-overlapping region B. [

The system 100 sets different color weights for the overlap region, border region and non-overlap region in the mesh of the reference bust model 420. Specifically, the color weights of the overlap area A and the border area C overlapping with the hat item 410 are set to 1, which is white, and the color weights of the non-overlap area B are set from the border area C You can set it closer to 0, which is black, as it goes farther away. Therefore, a gradation effect in which the non-overlapping region B in the mesh of the reference bust model 420 becomes closer to the black color as the distance from the boundary region C increases. This is to obtain a more natural combination result when the pressed hair is deformed to correspond to the reference bust model 420 by using the color weight and the deformed pressed hair is combined with the hat item 410 in the future.

The system 100 can create a virtual bust model 420 with a color weight set, as shown in FIG. 5, and use it to transform the pressed hair.

FIG. 6 is a view showing coordinates of a center of gravity of a triangle used in a character hat item combination according to an embodiment of the present invention. The system 100 retrieves the triangles that make up the mesh of the reference bust model created in FIGS. 5 and 6, and transforms the pressed hair using the center of gravity coordinates of the triangle.

Specifically, the system 100 detects any one of at least one triangle constituting the mesh of the reference bust model while superimposing the reference bust model and the pressed hair on the three-dimensional virtual space by matching the respective center points. Then, the vertex P closest to the detected triangle is searched for among the at least one vertex constituting the mesh of the pressed hair.

When the mth vertex (m is a natural number) is detected as a vertex close to any nth triangle (n is a natural number) among one or more vertices constituting the mesh of the pressed hair, the system 100 calculates the weight The deformation color weights to be applied to the mth vertex are calculated using the color weights of the center coordinates and the center-of-gravity coordinates of the nth triangle.

The modified color weights to be applied to the mth vertex can be calculated using the following equation (1).

In Equation 1, W _Vm is a modified color weights to be applied to the _{m-vertex, X 1, X 2, X} 3 is a center-of-gravity coordinates of the n-th _{triangle, W 1, W 2, W} 3 is the center of gravity of the n-th triangle The color weight of the coordinates.

For example, the first vertex is to assume that most closely with any of the 10 triangles, the center of gravity coordinates of the 10th triangle (X _1, X _2, X ₃₎ is (0.3, 0.1, 0.6), 10 When the color weights W ₁ , W ₂ and W ₃ of the center-of-gravity coordinates (X ₁ , X ₂ and X ₃ ) of the triangle are (1, 0.5, 0.7) The modified color weight (W _V1 ) can be calculated to be 0.77. In this way, the deformation color weight (W _Vm ) to be applied to all the vertices constituting the mesh of the pressed hair can be calculated.

On the other hand, if the deformation color weight W _Vm to be applied to the m vertex is calculated, the deformation color weight W _Wm corresponding to the m vertex of the vertex constituting the meshes of the character's normal hair, The coordinates of the vertex are used to calculate the coordinates of the new m 'vertex at which the mth vertex will be located. That is, coordinates of a new vertex for transforming the coordinates of one or more vertices constituting the mesh of the pressed hair to correspond to the reference shape model are calculated.

The coordinates of the new vertex where the mth vertex will be located can be calculated using the following equation (2).

In Equation (2), V _{m '} is a coordinate of a new m'th vertex to which the mth vertex is to be positioned, A ₁ , A ₂ , and A ₃ are coordinates of the mth vertex constituting the mesh of normal hair of the character, and B ₁ , B ₂ , and B ₃ are coordinates of the m-th vertex constituting the mesh of the pressed hair, and W _Vm is a deformation color weight to be applied to the m-th vertex.

For example, if the coordinates (A ₁ , A ₂ , A ₃ ) of the first vertex constituting the mesh of the normal hair of the character are (100, 50, 100) and the coordinates of the first vertex (W ₁ , B ₂ , B ₃ ) is 50, 50, 100 and the deformation color weight W _Wm to be applied to the first vertex is 0.77, The coordinates of the m'th vertex (Vm _' ) can be calculated as (61.5, 50, 100). In this way, a new m 'vertex (V _m' ) to which all the vertices that make up the mesh of the pressed hair can be located.

Then, by applying a deformation color weight corresponding to the m'th vertex (Vm _' ), it becomes possible to deform the pressed hair corresponding to the reference bust model.

FIGS. 7A through 7C illustrate results using a character hat item combination system according to an embodiment of the present invention. The system 100 can combine the normal hair 700 of the character shown in FIG. 7A with the first hat item 710 to obtain a combination result as shown in FIG. 7B. That is, the normal hair 700 of the character is deformed by the pressed hair, and the pressed hair is deformed to correspond to the first hat item 710 by using the reference bust model corresponding to the first hair item 710. Thus, the system 100 can transform the normal hair 700 of the character into a first hair 701, and combine the first hair item 701 with the first hair item 710 to form The same combination result can be obtained.

In addition, the system 100 can combine the normal hair 700 of the character shown in FIG. 7A with the second hat item 720 to obtain a combination result as shown in FIG. 7C. That is, the normal hair 700 of the character is transformed in the same manner as that applied in FIG. 7B and transformed to correspond to the second hat item 720. Thus, the system 100 can transform the normal hair 700 of the character into a second hair 702, and combine the second hair item 702 with the second hair item 720 to form The same combination result can be obtained.

FIG. 8 is a flowchart illustrating a method of combining a character hat item according to an embodiment of the present invention. The character hat item combining method shown in Fig. 8 can be implemented by the system 100 shown in Fig.

The system 100 generates a reference bust model corresponding to the hat item (step 810). The reference bust model can vary depending on the hat item and can be generated as a mesh of three-dimensional modeling data, ie, a reference bust model. In this case, the mesh of the reference bust model is divided into an overlap area, a border area and a non-overlap area based on the hat item, and each area can be set to a different color weight.

Then, the system 100 compresses the normal hair of the character and transforms the hair into the pressed hair (step 820). Specifically, a virtual bust mesh used to transform the normal hair of the character into the pressed hair and a virtual bust mesh are created in the inner space of the virtual bust mesh using the virtual bust mesh, the center curve, and the mesh of the normal hair of the character The character's normal hair is transformed into pressed hair.

Next, the system 100 deforms the pressed hair to correspond to the reference bust model (step 830). Specifically, the center of gravity of the triangle included in the mesh of the reference bust model is used to detect a vertex adjacent to the triangle among at least one vertex constituting the mesh of the pressed hair. Then, a deformation color weight to be applied to the detected vertex is calculated by using the gravity center coordinate system and the color weight of the triangle. In addition, the pressed vertex, the vertex constituting the mesh of normal hair of the character, and the deformed color weight calculated above correspond to the reference bust model.

Then, the system 100 combines the pressed hair and the hat item modified to correspond to the reference bust model (step 840).

According to the method shown in Fig. 8, it is possible to automatically and naturally combine the hat items by modifying and combining the normal hair of the character to correspond to the hat item.
