The 3D graphic data generation unit 202 can minimize the area of the individual polygon faces in consideration of the limitation of the polygon mesh. Here, an individual polygon face may mean a face as a component of a polyhedral object referred to in three-dimensional computer graphics. In addition, the limit of the polygon mesh may be to divide the polygon mesh into a plurality of paces based on the edge to maximize the smooth curvature of the figure.

In case of an output device capable of coloring, the three-dimensional graphic data coloring unit 303 may provide texture coordinates and color information of the three-dimensional graphic data. Coloring may be a method of physically outputting a color that changes in pixel units by injecting ink onto a powder after laminating a white powder in an output device that outputs a laminate type differently from molding a color of a single color . And, the output device can color all the positive normal faces to which the texture coordinates and colors are assigned. Therefore, the 3D graphic data coloring unit 303 may not assign the color information to the inner surface of the figure in consideration of the coloring method of the output device. At this time, the figure may be a figure whose thickness is determined.

The three-dimensional graphic data storage 304 may store three-dimensional graphic data.

The format conversion unit 305 may include a three-dimensional graphic data format unit 306. The format conversion unit 305 may convert the format of the three-dimensional graphic data into an output format that can be recognized by the output device. At this time, the format conversion unit 305 may correspond to the format conversion unit 203 of FIG.

The three-dimensional graphic data editing unit 307 may include an input data matching unit 308, an input data editing unit 309, and an input data storage unit 310. At this time, the 3D graphic data editing unit 305 can correspond to the volume area extraction unit 204 and the 3D graphic data editing unit 205 of FIG.

The input data matching unit 308 may use the three-dimensional graphic data as input data to be used as input in the output device. The input data matching unit 308 can check the integrity of the input data. More specifically, the input data matching unit 308 can match the input data corresponding to the three-dimensional graphic data and the format data of the output apparatus, and confirm the integrity of whether the input data can be used as input data in the output apparatus . The input data matching unit 308 can extract a volume area that can be output from the output device by using input data whose integrity is confirmed or can be used.

The input data editing unit 309 can edit the attribute of the input data in consideration of the size after the output of the figure and the convenience of the molding process.

The input data storage unit 310 may store the edited input data.

4 is a diagram illustrating an output result of a figure according to a state of a polygon mesh according to an embodiment.

In general, the output device can recognize the positive normal direction of the individual polygon faces of the polygon mesh as the outer surface of the figure. The positive normal direction may refer to the lines shown in the closed polygon mesh 401 and the thick polygon mesh 402 of FIG. In addition, the output device fills the volume area of the negative normal direction with the powder according to the polygon mesh 401 having a closed shape or the polygon mesh 402 having a thickness. The volume area may be an area filling the powder when the output device outputs a figure corresponding to the input data.

Based on the above, referring to FIG. 4, the closed polygon mesh 401 may be in a form that can be recognized by the output device as a continuous continuous polygon. As described above, in the case of the closed polygon mesh 401, the output device recognizes the individual polygon faces in the negative normal direction, so that the inside of the volume area is filled with the powder. In the output device, the volume of the volume area is filled with the powder, thereby increasing the amount of the powder used. In addition, the figure becomes heavier depending on the amount of powder used, and when a relatively heavy part is located at the upper part of the figure, the center of gravity shifts upward and the durability can be reduced by reducing the sense of stability.

On the other hand, the thick polygon mesh 402 may be formed in a part of the polygon mesh to form a discharge port, and the inside of the volume area may be emptied during molding. In other words, the thick polygon mesh 402 can be filled with powder as a thickness-determined portion. The graphic data processing apparatus can increase the stability of the center of gravity of the figure to be displayed by determining the thickness of the upper part of the figure which takes a large proportion in consideration of the center of gravity of the figure and emptying the inside of the volume area during molding. In addition, the graphic data processing device can determine the amount of powder to be used and the weight of the figure by determining the thickness of one layer of the polygon mesh to be at least a minimum thickness that can be formed taking into account the size of the figure and the proportion of each part. The graphical data processing apparatus does not determine the thickness of one layer of the polygon mesh according to the size of the figure, or determines the maximum thickness, thereby enhancing the durability of the figure. For example, the graphic data processing apparatus can form a closed polygon mesh shape without determining the thickness considering the output size of the figure for the portion corresponding to the thin and long portion in the entire proportion of the figure.

5 is a view showing an injection method of a figure according to an embodiment.

Referring to FIG. 5, the head 501 and the body 502, which occupy a large portion of the figures in proportion to the figures, are emptied. At this time, the discharge port can separate the head 501 and the body 502 of the figure, and can be produced at the neck connection portion with respect to the neck which does not hurt the beauty. In addition, the output device can be connected to the volume area of the head 501 and the body 502 separated with respect to the neck by filling the powder volume with a thickness of one layer of the specified polygon mesh, and then using an adhesive. The discharge port can be created at a natural boundary without detracting from the aesthetics of the figures.

6 to 7 are views showing an injection method of a head of a figure according to an embodiment.

Referring to FIG. 6, the head 501 can be separated into a hair 601 and a mask 602. The hair 601 and the mask 602 can be specified to have a constant thickness according to the ratio of the figures.

Referring to FIG. 7, the discharge port 701 may be formed at a connection portion where the hair 601 and the mask 602 can be formed. At this time, the discharge port 701 can be formed at a portion that is naturally connected without harming the beauty of the figure. The output device can form the hair 601 and the mask 602 using a discharge port to be formed at a connection portion between the hair 601 and the mask 602. [ Then, the output device can connect the mask 602 with the hair 601 formed using an adhesive.

8 is a view illustrating an injection method using an attachment according to an embodiment.

Referring to FIG. 8, the discharge port 801 may be formed using an attachment portion attached to the head portion. In other words, the discharge port can be formed by separately manufacturing a removable figure with a cap or a hair pin attached to the head.

In addition, the discharge port can be formed by separating the parts of the body which are not proportional to the figures and whose volume area is not large. In other words, the discharge port can be formed in a region where the volume area of the limbs of the human body, the tail of the animal, the fins, etc. is not large.

Further, the injection methods described in Figs. 5 to 8 are not limited to the description, and may include various ways of forming the discharge port. In addition, the injection method can be equally applied to various types of biped figures including figures of a human body model.

In step 901, the graphic data processing apparatus can generate three-dimensional graphic data to be used as input data of the output apparatus. The graphics data processing device may be created with a polygon mesh that is a collection of consecutive polygons that the output device can recognize. At this time, the polygon mesh may be a closed polygon mesh having a closed shape. And, the graphic data processing device can be divided so as to minimize the area of the individual polygon face in consideration of the limitation of the polygon mesh.

The graphic data processing apparatus can determine the minimum thickness of the polygon mesh necessary for the stable configuration of the shape in order to minimize the use of the material in the process of forming the figure outline. In other words, in order to stabilize the center of gravity of a portion occupying a large ratio such as an upper body, a head, etc. positioned at the upper portion of the figure, the graphic data processing apparatus can impart thickness to a polygon mesh of one layer for each of upper body, head,

Therefore, the graphic data processing apparatus can generate three-dimensional graphic data of the thickness-determined polygon mesh.

In step 902, the graphics data processing device may convert the format of the three-dimensional graphics data into a format recognizable by the output device. In other words, the graphic data processing device can convert the stored three-dimensional graphic data into an output format that can be recognized by the output device.

In step 903, the graphic data processing device can verify the integrity by matching the formatted three-dimensional graphic data with the format data of the output device. The graphic data processing device can check the integrity of the output device, and confirm that the output device recognizes the three-dimensional graphic data as outputable input data. Then, the graphic data processing device can extract the volume area in which the output device can be formed.

In step 904, the graphic data processing apparatus may edit the 3D graphic data in consideration of a molding process according to a volume area. More specifically, the graphic data processing apparatus can edit the attribute of the 3D graphic data in consideration of the size after the output of the figure and the convenience of the molding process according to the volume area.
