Description

3D design modeling method {METHOD FOR MODELING 3D DESIGN}

The present invention relates to a 3D design modeling method, and more particularly, to a 3D design modeling method for efficiently modeling a 3D object according to a model of a user terminal when processing 3D data.

Conventional GUI input devices are formed in the form of a mouse, a trackball device, a touch pad, and a point stick, and are mainly composed of a method of controlling a pointer (cursor) on a monitor. These devices process objects on the screen in a way of selecting and clicking through a pointer (cursor).

However, in an application program that additionally requires a function that requires rotation conversion as well as linear movement of an element on the screen, such as a CAD system or a 3D animation production tool, through the existing method, rotation is performed after the right click of the mouse. There was a limit to achieving the conversion goal only through various inconvenient steps such as having to select and drag.

This limitation was a natural result because the existing input device was designed around 2D, and it has been utilized without any particular inconvenience in the existing environment that was centered on 2D, such as editing text or images. However, the recent rapid development of computer systems and the continuous spread of high-speed networks made it possible to process more dynamic and visual data.

The role of 3D data is gradually increasing even in general-purpose environments such as Internet homepages, and the demands of users are also favoring 3D stereoscopic images, and accordingly, the demand to process 3D data is increasing rapidly. There is a demand for continuous development and dissemination of the technology for processing 3D data.

Therefore, the input method, which is the basic object control on the screen, also requires a three-dimensional input control rather than the existing two-dimensional input method. However, since the environment in which users communicate with 3D objects in the system is 2D, in order to process, edit and examine 3D data in a 2D environment, it is inevitable to rotate the object (model) on the screen back and forth, left and right. Since there is only one, there is an increasing demand for an effective three-dimensional conversion input device.

The above-described technical configuration is a background technique to aid understanding of the present invention, and does not mean a conventional technique widely known in the art to which the present invention pertains.

The image acquisition unit 220 may acquire an image of an object for which 3D object modeling is desired from the user terminal 10. In this case, the image acquired from the user terminal 10 may be a 3D image.

The model determination unit 230 determines the type of the user terminal 10 accessed through the communication unit 210 and a resolution supported by the user terminal 10. That is, the model determination unit 230 determines the model of the user terminal 10 based on the terminal information including the type and resolution information of the user terminal 10 received from the user terminal 10, and the determination result It transmits to the information setting unit 240.

Hereinafter, a 3D object modeling method using the 3D object modeling system configured as described above will be described in more detail.

3 is a flowchart illustrating a 3D object modeling method according to an embodiment of the present invention, and FIGS. 4A to 4D are diagrams illustrating an event of enlarging an object using the 3D object modeling method of FIG. 3, and FIGS. 5A to 4D 5D is a diagram illustrating an event of rotating an object using the 3D object modeling method of FIG. 3, and FIGS. 6A to 6D are diagrams illustrating an event of moving an object using the 3D object modeling method of FIG. 3.

3, the 3D object modeling method according to an embodiment of the present invention corresponds to a model of the user terminal 10 among images of objects set to at least one type of size through the user terminal 10. A first step (S10) of selecting and arranging an image of an object to be used, and a second step (S20) of three-dimensional modeling the image of the object according to the type of the event when an event is input by the user.

More specifically, in the first step (S10), an image of an object is photographed using a photographing means (ie, the camera device 1), and the photographed image is set to a first reference size of at least one type. The first process of registering with the modeling server 20 (S11), and a second process of selecting the type and resolution of the user terminal 10 by accessing the user to the modeling server 20 (S12) (S13), and , A second reference size for setting a second reference size of an image to be 3D modeled by the user according to the type and resolution of the user terminal 10 selected in the second process S13 among the first reference sizes set in the first process S11. A third process (S14) and a fourth process (S15) of selecting and arranging an image corresponding to the second reference size set in the third process (S14).

At this time, in the first process (S11), the user can model the image of the object photographed from the camera device into three types (for example, a small image (S), an intermediate image (M), and a large image (B)). You can register at (20).

In addition, in the third process (S14), the image sizes of two types of objects suitable for the type and resolution of the user terminal 10 among the three types of object image sizes set in the first process (for example, Small image (S), medium image (M)) can be selected.

In addition, in the fourth process S15, the first image may be first selected from among the second reference sizes of the image set in the third process S14 and arranged.

In the second step (S20), when the event is input by the user (S21), if the event is enlarged or reduced (S22), the size of the image of the object required by the enlargement or reduction is calculated. The process (S221) and, when the size of the image of the object calculated in the process 1-1 is smaller than the second reference size, the process 2-1 (S222) of selecting an image of the second reference size may be included. have. In this case, in step 2-1 (S222), when the size of the image of the object calculated in the first step is larger than the second reference size, an image having the largest size among the first reference sizes may be selected. For example, in step 2-1 (S2222), when the calculated object size is smaller than the small image S, the calculation is corrected and selected by the size of the small image S, and is larger than the small image S. If it is smaller than the image (M), the calculation is modified to the size of the intermediate image (M), and if it is larger than the intermediate image (M), the calculation can be modified and selected with the size of the large image (B) set by the user. In addition, in the second step (S20), when the image of the object of the calculated size and the current object image are different from each other, the image may be replaced with the object image of the original state (S224).

That is, when the event is enlarged or reduced, the required object image size is calculated due to the execution of the event, and then the required object image is loaded only when the required object image has not yet been loaded due to the enlargement or reduction, and if it is smaller than the already loaded image, You can use the image of the object that was loaded earlier.

Accordingly, when the event is enlarged, the image of the object 3D modeled through the second step S20 may appear as shown in FIGS. 4A to 4D.

In addition, in the second step (S20), when an event is input by the user, if the event is rotation (S23), the image of the object selected and placed in the fourth step (S15) is rotated. That is, when the event is rotation, no new traffic is generated no matter how much rotation is performed. Therefore, the rotation event is terminated when the user's manipulation is released after using the object image of the initial size that was initially loaded. This rotation event does not require a detailed view while the object image is rotating, so it is not necessary to use a high-resolution image, and a small resolution image loaded initially is used (S231), and the size of the current object image is determined when the rotation is finished (S232). ) And if you need a high-resolution image, you can load it at that time.

Accordingly, when the event is rotation, the image of the 3D modeled object through the second step S20 may appear as shown in FIGS. 5A to 5D.

In addition, in the second step (S20), when an event is input by a user, if the event is moved (S24), only the position of the image of the object selected and placed in the fourth step (S15) is changed and moved ( S241). This movement event moves the image of the object to the position calculated according to the event, and then the movement event ends when the user's manipulation is released.

Accordingly, when the event is a movement, the image of the 3D modeled object through the second step S20 may appear as shown in FIGS. 6A to 6D.

On the other hand, the 3D object modeling method according to the embodiment of the present invention can be written in a computer program. Codes and code segments constituting this computer program can be easily deduced by a computer programmer in the art. In addition, the computer program is stored in a computer readable media, and is read and executed by a computer or a modeling server 20 or a management server according to an embodiment of the present invention, thereby modeling 3D objects. The method can be implemented. The information storage medium includes a magnetic recording medium, an optical recording medium, and a carrier wave medium. A computer program implementing the 3D object modeling method according to an embodiment of the present invention may be stored and installed in an internal memory of the user terminal 10 or the modeling server 20. Alternatively, an external memory such as a smart card (for example, a subscriber identification module), which stores and installs a computer program for implementing the 3D object modeling method according to an embodiment of the present invention, is connected to the user terminal 10 or the modeling server ( 20) can also be mounted.

The 3D object modeling method according to an embodiment of the present invention configured as described above and the medium in which the computer program using the same is recorded are arranged with an appropriate object image size according to the model of the user terminal 10 when processing 3D data. And, since the image of the appropriate object is automatically selected based on the size of the image of the deformed object according to an event such as enlargement, reduction, rotation, or movement, the computational amount of the user terminal 10 can be reduced, Accordingly, it is possible to efficiently model a 3D object by suppressing the occurrence of traffic.
