Description

Method for manufacturing character models using three-dimensional character data}

The present invention relates to a method of manufacturing a character model using three-dimensional character data, and receives a character model that is used as a character representing a user in a virtual environment such as an online game, a messenger, or a chat, which is implemented in three dimensions It relates to a method of manufacturing a character model that can be produced.

Characters that visually represent the user are used in games, messengers, and web services. A character can be in the form of a person, or in the form of an animal or a creature present in the imagination.

Currently, characters used as personal alterations in online games, messengers, and chats are two-dimensional (2D) or three-dimensional (3D), and users can decorate their characters by purchasing items or accessories or accumulating experience points. have.

On the other hand, 'model making' based on analog characteristics is a field of hobby that has been enjoyed for over 400 years all over the world beyond local limits. However, in the late 1990s, the model market, which had grown based on mass production and mass distribution, began to slow down. This is a market trend that appeared as the two major axes of the model industry, the military model of precision modeling, and the character model field of re-animation, which began to be ignored by consumers due to the absence of ideology and killer content. Also, during this period, the development of leisure sports due to the development of sports, games, and digital hobbies began to slow down.

As a countermeasure, major companies that have led the model market are seeking ways to restructure their production systems based on cheap labor in China, and the resulting products are handcrafted with the motto of high quality, low cost, and small quantity production. It was a finished product.

As the products produced by the leading companies in the market are composed of finished products, the model market itself naturally becomes a collection type market. As the market changed, the business target was expanded from the enthusiastic modeler who enjoys the traditional assembly / painting process to the general public, and the market size also began to expand.

However, as the promotion of the collection's most basic rareness disappeared, product distribution long tails did not exist, and particularly, it was difficult to reflect personalized needs.

Developing a collection product must also have attractiveness of the product itself, and as a result, it is difficult to continue to bear the cost of exploring ideas, merchandising and commercialization, resulting in a slowdown in the overall model market. .

In addition, it is difficult for users who have already experienced the digitization era to return to traditional modeling with strong analog characteristics, and only the model as a perfume remains in memory.

The present invention relates to a method of manufacturing a character model that can manufacture and supply a character model at a low cost by ordering the user's character in an online game, a messenger, a chat, a web service, etc., which implements a user representing a user in a virtual environment in three dimensions. will be.

The present invention for achieving the above object,

a) receiving 3D data of the character from the 3D character-based virtual environment server;

b) analyzing the character 3D data and giving a thickness to an outer surface of the character;

c) transmitting the character 3D data to which a thickness has been given to a 3D printer; and provides a method of manufacturing a character model using a 3D character.

Preferably, the step a) includes converting the character 3D data received from the virtual environment server into a specific 3D format.

In step b), since 3D graphic data does not represent thickness, data is not suitable for realization. Therefore, in order to improve the thickness of the 3D graphic data, an object for each part is analyzed by analyzing the received character 3D data. It is preferable to determine whether the shape of the object is an open object or a closed object, and to give a thickness to the outer surface of the character according to the shape of the object.

In particular, when the shape of the object is a closed object, the thickness of the object is preferably given inward, and in the case of an open object, the thickness is given in the direction in which the center point of the object data is located.

In the case where the object shape is an open object among the character parts, the thickness of the center portion of the object is preferably thick, and the thickness is thinner toward the edge.

In the method of manufacturing a character model using the three-dimensional character data of the present invention, a character model can be obtained at a low cost by ordering a character that is used as an alternation representing a user in a virtual environment such as an online game, a messenger, or a chat, which is implemented in three dimensions. There is an effect that can be manufactured and supplied.

Hereinafter, a method for manufacturing a character model using the three-dimensional character data of the present invention will be described in detail with reference to Examples. The scope of the present invention is not limited to the following Examples.

1 is a flow chart schematically showing a method of manufacturing a character model using the three-dimensional character data of the present invention, Figure 2 is a control block diagram of a system for a method of manufacturing a character model using the three-dimensional character data of the present invention.

Method of manufacturing a character model using the three-dimensional character data of the present invention comprises the steps of receiving the 3D data of the character from the virtual environment server as shown in Figs. Analyzing the character 3D data and giving a thickness to an outer surface of the character; And transmitting the character 3D data given a thickness to a 3D printer.

First, 3D data of a character is received from a 3D character-based virtual environment server. The virtual environment server refers to a server for driving a 3D character-based game, chat, messenger, and the like. The virtual environment server may be an off-the-shelf service that is being serviced by another company that is already being serviced regardless of the present invention.

Users can connect to the virtual environment server through a network to create basic 3D characters, and apply personalized items or accessories to the characters while playing games to form personalized characters only for the user. The formed character is stored in the virtual environment server for each user ID.

Examples of items include tops, bottoms, cloaks, clothing, belts, hats, gloves, shoes, neckbands, rings, glasses, sunglasses, swords, shields, bows, guns, and all the segmentable things used to express characters. May be included.

Also, in the case of a character, a person may be shaped as a person, but is not limited thereto, and creatures such as an existing animal, an imaginary animal, and a plant may be shaped. In addition, not only the user's character expressed in the user's personality, but also characters generated irrelevant to the user, such as the NPC of the game.

The user determines the shape to model the 3D character by adjusting the style, motion, item wearing, etc. of the personalized character. In this case, the user may separately form the base part of the character so that the modeled character may be stably placed on the floor.

In addition, the user can set the size of the shape of the three-dimensional character before transmitting the shape of the three-dimensional character determined to the management server through the network, the preview is provided for the set three-dimensional character.

When the user sets the shape and size of the finally determined three-dimensional character, data about the three-dimensional character is extracted from the virtual environment server and stored in a three-dimensional specific format. For example, it may be converted and stored in any specific format capable of representing 3D graphic data among formats such as catia, 3D max, investor, CAD, Rhino, Maya, SoftImage, and the like.

When a command for manufacturing a character model for a 3D character stored in a specific format is requested from a user, the virtual environment server transmits 3D data of a 3D character through a network, and the 3D data is received by the management server.

Next, the character 3D data received by the management server is analyzed to give a thickness to the outer surface of the character.

Preferably, the management server includes a format conversion unit, and the format conversion unit converts the character 3D data received from the virtual environment server into a specific 3D format. In this case, the specific 3D format may be different from the format of the thickness generator that analyzes the character 3D data and gives thickness to the outer surface of the character. For example, even if the received data is a 3D max format, the 3D max format may not be suitable for data with thickness included, so that the converted data may be configured using a third file format.

In a virtual environment such as a game, character 3D data is mapped and viewed in three dimensions, but the character 3D data received by the management server is composed of only points forming the outermost surface of the character.

When the character model is produced by using the 3D printer by mapping the character 3D data received by the management server, the thickness of the 3D printed character model is too thin to maintain its shape intact.

Accordingly, the character 3D data received by the management server is analyzed by a data analysis unit, and then the thickness generation unit generates a thickness on the outer surface of the character to improve the strength of the character model.

At this time, the thickness given to the outer surface of the character is determined by the strength of the powder and the model used in the 3D printer. On the other hand, the character 3D data can be converted to a solid form, but the powder used in the 3D printer is expensive, there is a problem that the manufacturing cost of the character model is significantly increased.

If the thickness of the character is too thin, the strength of the character model is easily broken when the thickness of the character model is too low. If the thickness is too thick, the strength of the character model is excellent, but the manufacturing cost increases. It is enough to determine according to the strength and the like.

And if it is determined by the data analysis unit that the base part serving as a pedestal of the character model in the character 3D data received by the management server is not provided with the base portion data at the bottom of the character 3D data It is good to add.

3 is a diagram schematically illustrating a state in which a thickness is generated in a closed object, and FIG. 4 is a diagram schematically illustrating states in which a thickness is created in an open object.

On the other hand, the data analysis unit may analyze the character 3D data to determine whether the object shape of each part is a closed object or an open object.

The thickness generation unit gives a thickness in the case of the region of the character analyzed as the closed object by the data analysis unit, and in the case of the region of the character analyzed as the open object, gives the thickness in the direction in which the center point of the object data is located. It is desirable to.

As shown in FIG. 3, the thickness 110 is formed to extend inward with respect to the outer surface (including the outline and the points forming the outer surface) in the closed object 10, so that the digitized character is closer to the character model. Have a silhouette.

And in the case of the open object 30 as shown in Figure 4 is formed by extending the thickness 310 on both sides of the outer surface in the same manner (b1 of Figure 4), or extend the thickness 310 to the lower or upper side based on the outer surface 4 may be formed (b2 of FIG. 4), and the thickness 310 may be given in the direction in which the center point 1 of the object data is positioned to have a silhouette closer to the digitized character as shown in b3 of FIG. 4. Furthermore, it is preferable to give the thickness of the center of the object thick, and to give the thickness thinner toward the edge.

As such, the character 3D data provided with the thickness by the thickness generation unit is transmitted to the 3D printer. The 3D printer completes the character model by 3D printing as shown in FIG. 5 using the character 3D data having a thickness.
