1 is a view showing a flow of a method for updating a 3D object in a mobile terminal according to an embodiment of the present invention, Figures 2a to 2e is a 3D object for explaining the method of updating the 3D object shown in Figure 1, An example of an object is a diagram illustrating a monster character.

Referring to FIG. 1, first, a mobile terminal checks whether an update of a pre-stored stored version of a 3D object is necessary (S101).

The 3D object in the present embodiment refers to an object that can be displayed by combining images of a plurality of 3D partial pieces, and generally includes monsters, hunters, animals, men, women, robots, avatars, etc. that appear in an application of a mobile terminal. An example might be a game character.

In the case where the 3D object is a game character as described above, the 3D fragments may be body parts constituting the game character or clothes, belongings, and game items worn by the game character.

2A to 2C illustrate examples of monsters displayed in an application when the 3D object is a monster. In FIG. 2A, a logo of a service provider that services an application on the front surface of the monster is engraved (202-1). 2B shows an example in which the logo of the service provider is erased from the monster shown in FIG. 2A (204-1) and the hanbok hood (203-1) is worn, and FIG. 2C is shown in FIG. 2A. An example of removing a service provider's logo from a monster and wearing items such as a top and a cigarette is shown.

As a result of the checking in step S101, when an update of the stored version of the 3D object is required (S102), the detected part is detected by detecting which partial pieces of the 3D partial pieces of the latest version of the 3D object have changed compared to the stored version. Only the image of the partial piece is downloaded (S103).

Herein, assuming that the monster shown in FIG. 2A is a stored version, and the monster shown in FIG. 2B is the latest version, in this case, the heads of the monsters 201-2 and 203-2 and the modified partial fragments and The trunk 202-2 and 204-2 parts are detected and thus the latest version of the head 203-2 and the partial pieces of the trunk 204-2 are downloaded to the mobile terminal.

That is, the present embodiment is not the entire image of the plurality of partial pieces constituting the latest version (the whole image shown in FIG. 2E) but the image of the changed partial piece (203-2 and 204-in the image shown in FIG. 2E). By configuring only two parts to be downloaded, the transmission capacity can be greatly reduced, and the transmission speed can be increased.

In addition, in the case of downloading the entire image of the plurality of partial pieces constituting the latest version, the image of the plurality of partial pieces of the previous stored version and the image of the plurality of partial pieces of the latest version downloaded to the memory and storage during the update process. In the case of downloading only the images of some partial fragments changed as in the present embodiment, while the whole must be loaded and stored, the images of the entire partial images and the downloaded partial fragments of the plurality of partial fragments of the previous stored version are stored in memory and storage. Loading and storing only saves enough memory and storage resources for the entire update process.

The image of the partial fragments downloaded in step S103 is combined with the images of the 3D partial fragments of the pre-stored stored version to generate and store the latest version of the 3D object (S104).

Finally, the stored 3D object is displayed (S105).

3A to 3B illustrate a detailed data transmission / reception process between the mobile terminal 300 and the server 400 in driving an application for displaying a monster character according to an exemplary embodiment of the present invention.

First, referring to FIG. 3A, an application in which a monster, which is a 3D object, appears in the mobile terminal 300 is driven (S311).

When the application is driven in step S311, since the monster that is a 3D object must be dispilled on the application, in order to check whether the monster needs to be updated, the gateway 401 of the server 400 requests the latest version information of the monster (S312). ).

In this embodiment, the gateway 401 is a component that stores and manages metadata information of the 3D object in the server 400, and the web server 402 displays an image of the partial pieces constituting the 3D object. The component to store.

In configuring the server 400 for providing a service for an application according to the present embodiment, the gateway 401 includes a user login / authentication function, a communication session maintenance function with a user, a monster update check function, and a user with a web server. Access to 402 to provide link information for downloading the images constituting the 3D object, and the like, and store user information, monster metadata information, and link information of the web server 402 necessary for this. And to manage.

In the present embodiment, the metadata information of the 3D object stored in the gateway 401 is a frame for combining and displaying images of 3D fragments into one 3D image, and a coordinate code set for implementing an action animation of the 3D object. , A web server that stores application data indicating the characteristics, characteristics, and information of these 3D objects in the application, the latest version information, the details of the partial fragments updated from the latest version to the previous version, and the image of the latest version fragments. Link to 402, and the like.

That is, the mobile terminal 300 requests the latest version information among the metadata information of the monster stored in the gateway 401 (S312), and receives the latest version information of the monster in response thereto (S313).

Here, the latest version information may include numbering information for identifying a version, a last update date or time, and the like.

The mobile terminal 300 compares the version information of the stored version previously stored in the mobile terminal 300 with the latest version information provided in step S313 (S314).

As a result of the comparison in step S314, the mobile terminal 300 determines that the update is unnecessary when the stored version is the same as the latest version (S315), and displays the stored version of the monster on the main screen of the application without a separate download process. (S316).

3B illustrates a detailed data transmission / reception process between the mobile terminal 300 and the server 400 when it is determined that an update is necessary according to a comparison result of version information, and S321 illustrated in FIG. 3B. Since the processes S to S324 are the same as the processes S311 to S314 illustrated in FIG. 3A, the descriptions of the processes S321 to S324 are replaced with the descriptions of the processes S311 to S314 described previously.

The mobile terminal 300 determines that the update is necessary if the stored version is different from the latest version and the latest version is a newly released version compared to the stored version in operation S324 (S325), and the metadata of the monster is determined. Information is requested (S326).

The mobile terminal 300 receives the monster's metadata information in response to the request of step S326 (S327), and detects the newly updated partial fragment in the latest version of the monster based on the monster's metadata information. (S328).

The mobile terminal 300 checks whether the download of the step S327 is normally completed before the step S328, and there is a problem in the network connection between the mobile terminal 300 and the gateway 401 in the step S327 of downloading the metadata information of the monster. When the download of the monster metadata information is interrupted can be implemented so that the monster metadata information can be downloaded again.

For example, when the metadata information of the monster includes information on the details of the partial pieces updated in the latest version compared to the previous version, the detection of the updated partial pieces in step S328 may be more easily performed.

The mobile terminal 300 downloads the image of the updated partial fragment detected in step S328 by using a link of the web server 402 which stores the image of the latest version of the partial fragment among the metadata information of the monster provided in step S327. Request to the web server 402 (S329).

The mobile terminal 300 downloads an image of the updated fragment in response to the request in step S329 (S330).

The image of the fragments of the stored version of the monster pre-stored in the mobile terminal 300 and the image of the updated partial fragments downloaded in step S330 generates the latest version of the monster and stores it (S331).

The mobile terminal 300 checks whether the download of the update step S330 is normally completed before the step S331, so that the network between the mobile terminal 300 and the web server 402 in the step S330 to download an image of the updated fragment of the monster. If a connection problem occurs and the download of the updated fragment of the monster is interrupted, the updated fragment of the monster can be implemented so that the image can be downloaded again.

When the latest version of the monster is generated in step S331 and stored in the mobile terminal 300, the updated monster version information is updated to the latest version (S332), thereby completing the update of the monster.

Then, similarly to the step S316 shown in FIG. 3A, the stored version of the monster is displayed on the main screen of the application (S333).

In the case of updating the 3D object in the mobile terminal according to the present embodiment, the network load between the mobile terminal and the server is reduced by downloading only the partial image of the partial fragment instead of downloading the entire image of the 3D fragments constituting the 3D object. In addition, it can reduce the memory or storage resources required for updating 3D objects.

 Accordingly, the partial fragment of the 3D object can be updated in real time, and the advertisement fragment or the logo of the advertisement target company is included in the image of the partial fragment of the 3D object to be useful for an advertising service targeting a mobile terminal. Can be.

The 3D object updating method according to the present invention can also be embodied as computer readable code on a computer readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and may be implemented in the form of a carrier wave (for example, transmission over the Internet) . In addition, the computer-readable recording medium may be distributed over network-connected computer systems so that computer readable codes can be stored and executed in a distributed manner. In addition, functional programs, codes, and code segments for implementing the present invention can be easily inferred by programmers of the technical field to which the present invention belongs.
