The line extraction module 110 may extract an outline from the 2D image.

Meanwhile, the 2D image may include a 2D object, and the line extraction module 110 may extract an outline corresponding to the 2D object or the 2D image from the 2D image.

For example, the 2D image 10 of FIG. 3 includes a 2D object, a figure and a character (VCL), and the 2D image 21 of FIG. 4 includes a 2D object of a star shape.

As described above, the line extraction module 110 can extract the outline of the 2D image. The outline of the 2D image may refer to a line forming the boundary of the 2D image. For example, the line extraction module 120 may extract the contour 11 of the 2D image 10 from the 2D image 10 of FIG.

Meanwhile, the line extraction module 110 may extract the outline of the 2D object included in the 2D image. The outline of the 2D object may refer to a line forming the boundary of the 2D object. For example, the line extraction module 120 may extract an outline 22 of an object included in the 2D image 21 from the 2D image 21 of FIG.

In one embodiment, the line extraction module 110 may extract a convex hull of a 2D object included in the 2D image as an outline of a 2D object.

In another embodiment, the line extraction module 110 may extract the outline of the 2D object based on the alpha value (transparency) of each pixel included in the 2D image. In the case of the 2D image, since the alpha value is set to a certain value or less except for the part constituting the object, in order to judge the object included in the 2D image, the line extraction module 120 extracts the alpha value of each pixel, (For example, 0) or less, and extract the outline of the 2D object constituted by the selected pixels.

The 2D mesh generation module 120 may generate a 2D mesh by performing a tessellation on a 2D surface formed by the extracted outline. A 2D mesh filled with a polygon (for example, a triangle or a square) from the 2D surface formed by the outline may be generated through a tessellation process performed by the 2D mesh generation module 120. [ For example, the 2D mesh generation module 120 may generate a 2D mesh 12 by performing tessellation on a 2D surface formed by an outline (1) of the 2D image of FIG.

The 3D mesh generation module 140 may generate a 3D mesh based on the outline extracted by the line extraction module 110. [

In one embodiment, the 3D mesh generation module 140 may generate the 3D mesh by inflating a 2D surface formed by the extracted outline. More specifically, the 3D mesh generation module 140 may generate a 3D mesh corresponding to the 2D object by inflating the 2D mesh generated by the 2D mesh generation module 120. For example, the 3D mesh generation module 140 may generate the 3D mesh 14 by inflating the 2D mesh 12 as shown in FIG.

5 is a view for explaining a method for the 3D mesh generation module 140 to generate a 3D mesh from a 2D plane. Referring to FIG. 5, the 3D mesh generation module 140 may perform pixel-level equal-interval sampling on a 2D plane as shown in FIG. 5 (a). Then, the 3D mesh generation module 140 extracts boundaries by a two-dimensional marching cube algorithm for the inside and outside of the sample vertices, and calculates a vertex partition set S ⁱ (Manhattan distance) by a distance L ¹ Where S ⁰ is a set of vertices forming a boundary, S ¹ is a set of vertices connected by direct edges to a vertex included in S ⁰ , S ^j (2 <= 0) j <= n) is a set of vertices not belonging to S ^j-2 among the vertices connected to the direct edge by the vertex included in S ^j-1 . Also, the 3D mesh generation module 140 may interpolate the height (z ⁱ ) of the vertex division set S ⁱ (0 <= i <= n) at various scales. In particular, the 3D mesh generation module 140 can interpolate the height of the 3D mesh so that the height increases as the distance from the boundary increases. For example, the height (z) of a particular vertex partitioning set may be any function (e.g., z = log (x + 1)) that monotonically increases with respect to the L ¹ distance (x) Etc.) (see Fig. 5 (b)). Then, the height (z) of the interpolated vertex division set is applied to the 2D mesh to generate a 3D mesh as shown in FIG. 5 (c).

The texture generation module 130 may generate the texture information to be embedded in the 3D object by mapping the 2D image to the 2D mesh. For example, the texture generation module 130 may generate the texture information 13 by mapping the 2D image 10 to the 2D mesh 12 as shown in FIG. In one embodiment, the texture generation module 110 may generate texture information by mapping each polygon included in the 2D mesh with a corresponding pixel on the 2D image.

The 3D object generation module 150 may generate a 3D object based on the 3D mesh generated by the 3D mesh generation module 140 and the texture information generated by the texture generation module 130. In one embodiment, the 3D object generation module may generate the 3D object by reflecting the texture information generated by the texture generation module 130 on the generated 3D mesh. For example, the 3D object creation module 150 may generate the 3D object 15 based on the 3D mesh 14 and the texture information 13 as shown in FIG.

The rendering module 160 may render the generated 3D object and display the 3D image corresponding to the 2D object on the user terminal 200. [

Meanwhile, when a 3D image is displayed on the touch screen 210 on the user terminal 200, the user can input a selection command for the 3D image by selecting (for example, touching) one of the 3D images . When the selection command for the 3D image is inputted, the simulation module 170 can simulate the pressure applied on the 3D object to be deformed. The simulation module 170 may simulate a case where a pressure is applied to a point that the user selects (e.g., touches).

In one embodiment, the simulation module 170 may simulate the application of pressure on the 3D object using mass-spring-damper simulations. For example, the simulation module 170 may simulate a deformed shape 16 by pressure when a 3D object 15 as shown in FIG. 3 is selected.

Meanwhile, since the mass-spring-damper simulation is a well-known simulation method widely used to represent a realistic deformation of an elastic object, a detailed description thereof will be omitted.

Meanwhile, the rendering module 70 may render the simulated result (i.e., a transformation of the 3D object).

Meanwhile, in one embodiment, the 2D image is a 2D icon, and the 3D image may be a 3D icon. Accordingly, the 2D image may correspond to a specific file or folder or correspond to a specific action (function). When the 3D image selection command is input, the action execution module 180 may perform an action (e.g., selecting or executing a file or a folder or a specific function) mapped to the 2D image selection command have.

Hereinafter, a 3D image providing system 100 according to an embodiment of the present invention will be described with reference to FIG. 4 to generate and render a corresponding 3D image from a 2D image.

Referring to FIG. 4, the 3D image providing system 100 may extract an outline 22 corresponding to the 2D object from a 2D image 21 including a star-shaped 2D object. In addition, the 3D image providing system 100 generates a 2D mesh by performing tessellation on a 2D surface formed by the extracted outline 22, inflates the generated 2D mesh, The 3D mesh 23 can be generated.

The 3D image providing system 100 maps the 2D image to the 2D mesh to generate texture information to be embedded in the 3D object, and generates 3D texture information based on the generated 3D mesh 23 and texture information, (24).

When the 3D image selection command is input, the 3D image providing system 100 simulates a pressure applied on the 3D object to be deformed (refer to reference numeral 25 in FIG. 4), and renders the simulation result (See reference numeral 26 in Fig. 4).
