Referring to FIG. 1, the system environment may include a 3D modeling device 1, a server 2, and 3D modeling devices 3.

The 3D modeling device 1 may serve to provide a working environment to a user to perform a 3D modeling task. The 3D modeling device 1 may transmit and receive various data related to 3D modeling from the server 2 or 3D modeling devices 3. Here, the 3D modeling device 1 may mean a PC, but mobility (portability) such as a smart phone or tablet PC with an application for performing the 3D modeling method is installed. At the same time, it can include high-performance portable electronic devices that can be installed with various applications. Here, the 3D modeling device 1 may be a terminal currently used by a user, and the 3D modeling device 3 may be a terminal used by another user.

In addition, the 3D modeling device 1 may store 3D modeling data in an archive form. In one embodiment, the archive is a collection of files in one place for backup, archiving, or other purposes for file transfer, and refers to files in a directory or catalog.

Here, various data related to 3D modeling may include various data generated in the process of users performing 3D modeling. For example, various data related to 3D modeling may include a 3D model parametric, a parametric change amount, user information, a plurality of parameter values, and a parametric change history.

Next, a 3D modeling method of the 3D modeling apparatus 1 will be described with reference to FIG. 2.

 2 is a flowchart illustrating a flow of a 3D modeling method according to an embodiment.

Referring to FIG. 2, first, the 3D modeling apparatus 1 may provide a basic parametric of the 3D model to the user (S10). That is, the 3D modeling apparatus 1 may provide basic parametrics of a plurality of 3D models for each type of fashion item.

Here, the basic parametric of the 3D model is a minimum unit for 3D modeling of fashion items, and may be a basic frame for performing 3D modeling work. In addition, the basic parametric of the 3D model is pre-stored in the 3D modeling device 1, but the 3D modeling device 1 derives the basic parametric of the additional 3D model based on the results of 3D modeling work of multiple users. Can be stored and provided to the user. Through this, it is possible to provide a user with a basic parametric of a 3D model that fits the trend of a rapidly changing fashion item.

In addition, the 3D modeling apparatus 1 provides a user with a basic parametric of a 3D model including a plurality of parameters, so that 3D modeling can be easily performed only by changing parameters.

Specifically, the 3D modeling apparatus 1 may provide basic parametrics of a plurality of 3D models based on the user's setting value. Here, the setting value is a condition input by the user for modeling work, and may include the type, style, and design of a fashion item. Here, the style may include the presence or absence of a pleat or a ruffle, and the design may include the presence or absence, type and degree of a pattern, and the type of material. Meanwhile, the above-described setting value is one embodiment, and may further include additional setting values required to provide basic parametric.

In addition, the basic parametric of the 3D model may include at least one parameter that can change the shape of the 3D model. In addition, the type of the parameter included in the basic parametric of the 3D model may vary according to the fashion item type, and the default value of each parameter may also be different.

Here, the shape, shape, and color of the 3D model may be changed according to the value of the parameter. Accordingly, the user can perform a 3D modeling operation by selecting a basic parametric of the 3D model and changing a plurality of parameter values. In other words, the 3D modeling device 1 provides a basic parametric of a 3D model that is a basic frame for each type of fashion item, and provides parameters for changing the shape of the 3D model, so that even a user without expert knowledge can easily 3D Modeling can be performed. The types of specific parameters will be described later in the description with reference to FIG. 6.

Next, the 3D modeling apparatus 1 may acquire a first parametric change amount from the first parametric generated as a user input for generating 3D modeling data (S20). Therefore, the 3D modeling apparatus 1 can determine the first parametric change amount from the first parametric. Here, the parametric means having a structure related to each other using a plurality of parameters. Specifically, parametric refers to a 3D model representing a plurality of parameters based on an algorithm. That is, parametric means a 3D model expressed by combining a plurality of parameters with an algorithm.

In addition, the change amount of the parametric means the basic parametric of the 3D model and the degree of change of the parametric after the 3D modeling work. Or, it means the degree of change of the parametric before the work and the parametric after the 3D modeling work. That is, the change amount of the parametric may indicate the change amount of the plurality of parameters, and may be determined according to the change amount of each of the plurality of parameters. A detailed method of determining the amount of change in the parametric will be described later with reference to FIG. 3.

Next, the 3D modeling apparatus 1 may compare the obtained (determined) first parametric change amount with the second parametric change amount (S30). Here, the second parametric change amount may be a change amount related to the second parametric generated in a process in which another user performs 3D modeling before the first parametric is generated. Also, the second parametric may be obtained from various data related to 3D modeling received from the server 2 or other user's 3D modeling devices 3.

Specifically, the 3D modeling apparatus 1 may compare the first parametric change amount and the second parametric change amount determined based on parameter values having a selected depth or more. Alternatively, the 3D modeling apparatus 1 may compare the first parametric change amount and the second parametric change amount determined by assigning a weight to each parameter based on the frequency of modifying the parameter value.

That is, the 3D modeling apparatus 1 may determine the first parametric change amount and the second parametric change amount determined in the same environment. Here, the same environment may mean a case in which the selected depth is equal to or greater than a specific value or equal in weighting when determining the parametric change amount, and may mean a case in which there is no special condition.

Next, the 3D modeling apparatus 1 may provide pre-stored 3D model data of another user according to the comparison result of the first parametric and second parametric changes (S40). Specifically, the 3D modeling apparatus 1 has a difference between the first parametric and the most parametric change when the first parametric change amount and the second parametric change amount are the same or within a predetermined predetermined error range, or among a plurality of second parametric values. By selecting fewer parametrics, 3D model data corresponding to the second parametric may be provided to the user. Here, the 3D model data may be image data showing an example of a 3D model, and may include actual 3D modeled result data. Also, the 3D modeling device 1 may output a 2D image showing an example of the 3D model to the user.

Here, the pre-stored 3D model data of another user corresponding to the second parametric may refer to a result of 3D modeling generated as a second parametric derived as a result of 3D modeling work of another user. That is, the pre-stored 3D model data of another user corresponding to the second parametric may refer to another user's parametric having a second parametric change amount.

That is, the 3D modeling apparatus 1 may predict and provide pre-stored 3D model data of another user as a 3D modeling result of the current 3D modeling work based on the comparison of the first and second parametric changes.

As described above, by predicting and providing the 3D modeling result, the user can reduce the time to manipulate the parameter, and there is an effect that the user can obtain the unexpected 3D modeling result.

In addition, the 3D modeling apparatus 1 provides a user with a result of 3D modeling of another user based on the comparison of the change amount of the first parametric and the change amount of the second parametric, thereby 3D reflecting the user's 3D modeling direction or intention The result of modeling can be provided to the user.

Next, an embodiment in which the 3D modeling apparatus 1 determines the change amount of the first parametric will be described with reference to FIG. 3 and Table 1 below.

3 is an exemplary view showing a change in parameter a according to an embodiment.

<Calculate the average change amount of parameters in the parametric>

The 3D modeling apparatus 1 may determine an average change amount of parameters in the parametric as a parametric change amount.

For example, as shown in Table 1 below, when a plurality of parameter values are changed by modeling from parametric A to parametric B, the 3D modeling apparatus 1 may determine the average value of the change amount of each parameter as the change amount of the parametric. have.

The 3D modeling apparatus 1 may determine that the average +3 of the change amount of parameter a +2, the change amount of parameter b +4, and the change amount of parameter c +3 is a parametric change amount.

Parameter a Parameter b Parameter c Parametric A One 2 3 Parametric B 3 6 6

Therefore, the amount of change in parametric can represent the average degree of change of various parameters from the reference point.

<Change amount of each parameter in the parametric>

The 3D modeling apparatus 1 may determine each change amount of the parameters in the parametric as a parametric change amount.

For example, when a plurality of parameter values are changed by modeling from parametric A to parametric B as shown in Table 1 above, the 3D modeling apparatus 1 may determine each change amount of the parameter as a change amount of the parametric.

Specifically, the 3D modeling apparatus 1 may determine each of the change amount of the parameter a +2, the change amount of the parameter b +4, and the change amount of the parameter c +3 as a parametric change amount. That is, the change amount of the parametric may be (+2, +4, +3).

As described above, by determining the change amount for each parameter as the change amount of the parametric, the change amount of the parametric can show the change direction of each of the various parameters.

<Amount of change by weighting each parameter in the parametric>

The 3D modeling apparatus 1 may determine the first parametric change amount after assigning weights to the parameters in the first parametric according to the frequency with which the user modifies the parameter values in the process of modeling. Here, the frequency of modifying the parameter value means the number of times the user has changed the parameter in order to modify the parameter value in the process of modeling. Here, the weight is an importance given to each parameter, and may be determined according to the frequency with which a user modifies the parameter value in the process of modeling, and the weights assigned to each parameter may be different or the same.

For example, in Table 1 above, when the user changes parameters a, parameter b, and parameter c 4, 1, and 1 times respectively, and then changes from parametric A to parametric B, the 3D modeling device (1 ) May assign weights to parameters a, b, and c, respectively 5, 2, and 2, and then determine the first parametric change.

In addition, the 3D modeling apparatus 1 applies a weight to each parameter in the first parametric only when the frequency at which the user modifies the parameter value in the process of modeling exceeds a preset frequency criterion, and then the first The amount of parametric change can be determined. Here, the preset frequency reference may be set by the user, and may be automatically set according to the user's modeling work pattern.

That is, the 3D modeling apparatus 1 may determine the first parametric change amount by imposing a higher weight by significantly determining the parameter value modified by the user frequently.

Accordingly, the 3D modeling apparatus 1 may determine a parametric change amount by assigning a weight according to the frequency with which a user modifies a parameter value, thereby determining a modeling direction desired by the user as a parametric change amount.

<Amount of change considering the depth of each parameter in the parametric>

The 3D modeling apparatus 1 may determine a change amount of the first parametric by further considering a depth indicating the frequency at which the parameter value is selected while the user performs modeling. That is, the 3D modeling apparatus 1 may determine the amount of change in the parametric in consideration of the number of times the parameter value has been selected by the user to change the parameter value. Here, the depth may be determined for each parameter value according to the number of times the parameter value is selected in the process of the user performing modeling. This will be described with reference to FIG. 3.

Referring to FIG. 3, while the user performs modeling, the parameter a value may be changed in the order of 30 to 50, 80, 50, 80, and 100 in the first order. When the user performs modeling, if parameter a value 30 is 1, parameter a value 50 is 2, parameter a value 80 is 2, parameter a value 100 is 1, parameter a value 30 is depth 1, parameter The a value 50 may be depth 2, the parameter a value 80 may be depth 2, and the parameter a value 100 may be depth 1. That is, as the same value of the parameter a is selected several times, the depth of the corresponding value may be increased.

In addition, the 3D modeling apparatus 1 may determine a change amount of parametric in consideration of depth. Specifically, the 3D modeling apparatus 1 may determine a change amount of the parametric based on a parameter value having a predetermined depth or more.

For example, when determining a change amount of a parametric based on a parameter value having a depth of 2 or more, the 3D modeling apparatus 1 may determine a change amount of a parametric based on a change amount of 50 to 80 of the parameter a. . That is, the parameter 30 having the depth 1 and the value 100 of the parameter a may not be considered when determining the change amount of the parametric. If the depth is not taken into account when the 3D modeling device 1 determines the change amount of the parametric, the 3D modeling device 1 determines the change amount of the parametric based on the change amount of the section from 30 to 100 of the parameter a. You can.

When the depth criterion is high as described above, the basic start value and the final selection value of the parameter may be excluded. The result of determining the amount of change by applying the depth represents a main area of interest for selecting the parameter value of the user. Based on this, the 3D modeling apparatus 1 determines a change section [50 to 80] according to the depth of the first parametric as a change amount, and a change section [X to Y] according to the depth of the second parametric as a change amount By determining and comparing, the main change section of the parametric can be compared as a region of interest.

In addition, when determining the first parametric change amount and the second parametric change amount in consideration of depth, the 3D modeling apparatus 1 determines the first parametric change amount and the second parametric change amount including the final selection value regardless of the depth. You can also decide.

In one embodiment, when additionally considering the final selection value, the amount of change in the parameter considering depth 2 or higher may be determined as a selection value higher than a reference depth and a final selection value. That is, the 3D modeling apparatus 1 may determine the change amount of the parametric based on the change amount of the section from 50 to 100 of the parameter a.

If the depth is not taken into account when the 3D modeling device 1 determines the change amount of the parametric, the 3D modeling device 1 determines the change amount of the parametric based on the change amount of the section from 30 to 100 of the parameter a. You can.

Accordingly, the 3D modeling apparatus 1 determines the amount of parametric change in consideration of the depth, which is the frequency at which the parameter value is selected, while the user modifies the parameter value, so that the parametric change more corresponding to the direction of change of the 3D model intended by the user The amount of change can be determined. In addition, the 3D modeling apparatus 1 can increase the calculation speed by determining the amount of change in parametric by a parameter having a predetermined depth or more. Here, the criterion of the predetermined depth may be determined by the user, or may be automatically determined as an appropriate predetermined depth according to the user's use.

Meanwhile, the second parametric change amount of FIG. 2 may also be calculated according to the above-described method for determining (acquiring) the change amount of the parametric.

Then, the above-described parametric change amount may be compared with the obtained first parametric change amount and the second parametric change amount.

Next, a 3D modeling method of the 3D modeling apparatus 1 according to another embodiment will be described with reference to FIG. 4.

4 is a flowchart illustrating a flow of a 3D modeling method according to another embodiment.

Referring to FIG. 4, the 3D modeling apparatus 1 may provide a basic parametric of the 3D model to the user (S100). The specific contents are the same as in step (S10) described above.

Next, the 3D modeling apparatus 1 may determine a change history of the first parametric from the first parametric generated as a user input for generating 3D modeling data (S200). Specifically, the 3D modeling apparatus 1 may determine the change history of the first parametric from the change history of a plurality of parameters changed in the process of the user performing modeling. Here, the change history may include a change order of parameters and a change pattern. A specific method of determining the change history of the parametric using the change order and change pattern will be described later with reference to FIG. 5.

Next, the 3D modeling apparatus 1 may compare the first parametric change history and the second parametric change history (S300). Here, the second parametric change history may be generated in the process of other users performing modeling before the first parametric change history is generated. Also, the second parametric change history may be obtained from various data related to 3D modeling received from the server 2 or other user's 3D modeling devices 3.

Specifically, the 3D modeling apparatus 1 may compare the first parametric change history and the second parametric change history determined based on parameter values having a selected depth or more. Alternatively, the 3D modeling apparatus 1 may compare the first parametric change history and the second parametric change history determined by assigning a weight to each parameter based on the frequency of modifying the parameter value.

That is, the 3D modeling apparatus 1 may determine the first parametric change history and the second parametric change history determined in the same environment. Here, the same environment may mean a case in which the selected depths are the same or the weighting is the same when determining the parametric change amount, and may mean a case without special conditions.

Next, the 3D modeling apparatus 1 may provide pre-stored 3D model data of another user based on the comparison of the first parametric change history and the second parametric change history (S400). Specifically, when the first parametric change history and the second parametric change history are the same or within a predetermined error range, the 3D modeling apparatus 1 previously stored 3D model of another user corresponding to the second parametric change history Data can be provided to the user. Hereinafter, the detailed content is the same as the description of step (S40) described above.

Meanwhile, the second parameter provided to the user in step S40 of providing a second parametric based on the comparison of the parametric change amount described above and step S400 of providing a second parametric based on a comparison of the parametric change history. Metrics may be provided for free, but may also be provided for a fee. Therefore, the user may have to spend a certain cost to use the provided second parametric, and the expended cost may be provided to the person who provided the second parametric or provided to the provider of the server 2.

Therefore, the 3D modeling device 1 can recommend a parametric generated and stored in the process of performing 3D modeling to other users to induce purchase, and provide a platform for generating revenue to 3D modeling data providers. have.

Meanwhile, the present invention has described the 3D modeling methods of FIGS. 2 and 4, respectively, but two modeling generation methods can be considered simultaneously. For example, the present invention can perform both the step of determining the first parametric change amount (S20) and the step of determining the first parametric change history (S30), and comparing the first and second parametric change amounts. Both the step S30 and the step S300 of comparing the first and second parametric change histories can be performed. In addition, the present invention may be performed in a different order of each step described above.

Next, an example of a method of determining the first parametric change history of the 3D modeling apparatus 1 will be described with reference to FIG. 5.

5 is an exemplary view showing a change in parameter a according to an embodiment.

<Consideration of change order and change pattern of parameters in parametric>

The 3D modeling apparatus 1 may determine a first parametric change history based on a change order and a change pattern of a plurality of parameters that are changed during a user modeling process. Here, the change pattern means that the parameter value is changed in an iterative order or an iterative change amount.

For example, when the parameter value changes in the order of 0, 30, 20, 10, 60 and the parameter value changes in 0, 20, 30, 40, 60, the amount of parametric change may be the same, but the parameter By considering the order of change of values, the 3D modeling apparatus 1 may determine each first parametric change history differently.

In addition, the 3D modeling apparatus 1 may determine the change history of the first parametric from the parameter change history excluding the change history of the parameter of the section in which the parameter value is recovered. That is, when determining the change history of the first parametric, the 3D modeling apparatus 1 may not consider the change history of the section in which the parameter value is returned to the original state.

Referring to FIG. 5 in connection with this, while a user performs modeling, the parameter a value may be changed from 0 to 10, 0, 10, 20, 15 in the order of the first. In this case, the 3D modeling apparatus 1 first parameter based on the parameter change history of the section changed in the order of 0, 10, 20, 15 except for the section in which the parameter a value returns to 0 through 0 to 10. It is possible to determine the change history of the metric.

As described above, by determining the change history of the first parametric based only on the parameter change history excluding the section where the parameter value is restored to the original state, the change history of the first parametric corresponding to the change direction of the 3D model intended by the user is determined. You can. In addition, by excluding a constant section among the sections in which the parameter value changes, the load on the task of determining the change history of the first parametric can be reduced.
