(Max Ref x) - (Min ref x) = x length of model

(4,4,2) - (3,4,2) = (1,0,0) => length is 1 on x coordinate

(Max Ref y) - (Min ref y) = y length of model

(4,4,2) - (4,3,2) = (0,1,0) => length is 1 on y coordinate

(Max Ref z) - (Min ref z) = z length of model

(4,4,4) - (4,4,3) = (0,0,1) => length is 1 on z coordinate

Referring to FIG. 6 , the rotation data is fixed to the 3D model property, and the rotation data has two types of variable values: an axis to rotate (An axis name to rotate) and an angle (Degree).

Since the axis is selected to rotate the component, depending on the desired direction, the rotation may be performed in one axis such as the x, y, or z direction, or in the x axis followed by the y axis, or the x axis followed by the z axis, etc.

For example, ① If the component is to be rotated in the y-axis direction, the y-axis is selected. ② And, set the angle for rotation.

7 is an exemplary diagram for explaining a diameter calculation function (Radius Calculation Function).

Referring to FIG. 7 , if the 3D model is not a spherical body, a large spherical object circumscribes the 3D model in 3D. Then, the diameter of the sphere is calculated.

If the 3D model is a perfect sphere, calculate the diameter value of the sphere.

In addition, there is a Coordination Calculation Function, in which the center point of each 3D model is coordinated with a position (position) in 3D space. This is one of the functions needed to set the exact point when the primary 3D model and the secondary 3D model are merged.

The 3D model classification module plays a role in defining the 3D model type (eg, primary 3D model, secondary 3D model, reference, etc.) by secondary attributes of the 3D model.

The 3D model data cleaner module searches for and deletes garbage data, such as reference models, geometry data, lighting, and cameras, created for calculations that are no longer used.

In the present invention, the 3D model database is composed of a database system such as RDBMS, Graph Database, NoSQL, etc. and a file system.

When it comes to 3D model data, the 3D model can be defined in any 3D format, and this format can be stored as a text file in a file system or a database. .

A 3D model file stored in a file system may be compressed. The reason for compression is that it can improve the download speed.

Also, the 3D model file can be divided into several files and stored in the file system. The reason for dividing is that download speed can be improved by performing parallel file download.

Through such compression and file division, the page downloading speed in the customer terminal 20 can be improved.

The details of the 3D model are attributes (3D Model Attributes), for example, the maximum value, the minimum value, the x,y,z length value of the model, the diameter, the rotation x,y,z coordination value, and the variables of the geometry pattern. can be These attributes are stored in the database 120 .

8 to 9 are diagrams for explaining an adjustable 3D model design module according to an embodiment of the present invention.

Referring to FIG. 8 , the adaptive 3D model design module displays the primary 3D model in the canvas 710, and performs geometry modification of secondary 3D models and the primary 3D model.

When the customer accesses the purchase page using the customer terminal 20, the primary 3D model, attributes related to the primary 3D model file, secondary 3D model list, and other related data such as related attributes and references are stored on the server. It is loaded at (100). Therefore, in the present invention, it is possible to set a design tool capable of modifying 3D models in real time.

In this case, 0 or more secondary 3D models may be automatically calculated and listed on the purchase page. Also, the main 3D model can have zero or more references.

For reference, the Html Canvas is an HTML element used to represent graphics when using or working with a 3D model in real time. Here, 'use' means expressing elements such as enlargement, reduction, rotation, and geometry transformation of the 3D model in real-time 3D form by the customer's manipulation, and 'operation' refers to the main 3D file and secondary What is expressed on the canvas 710 through merging and selection between 3D files, and any other 3D model expressed on the canvas 710, means all.

References that follow the main 3D model are loaded when the main model is loaded. In FIG. 8 , selection 1 and selection 2 may be selected, and a design tool such as geometry transformation may also be a reference.

So, for example, if the main 3D model has two different references, the list of secondary 3D models shown in the next step within each designated reference is applied, so flexible design expression is possible within infinite possibilities. .

Next, a list of secondary 3D models according to the main 3D model is provided, including variable values for various manipulations including size, position, and geometry adjustment, the maximum and minimum values of the length of the x, y, and z axes, and some related properties of the secondary 3D model. Attributes and items are calculated and listed.

For example, it is possible to create a limit value for classifying secondary models through the maximum and minimum values of the lengths of the x, y, and z axes. If the x, y, z length of the secondary 3D model is within the limits, the model can be displayed in the called list.

Otherwise, it is not automatically listed.

Next, when the customer terminal 20 selects (clicks) one secondary 3D model from the automatically listed list by the customer, the secondary 3D model is loaded from the server to the canvas 710 on the web page. The loaded secondary 3D model is called together with the combination of secondary 3D model reference coordination values (size, rotation, diameter, adjustment values, etc.) set according to the design of the primary 3D model in the 3D model space, and is completely merged with the primary 3D model. make up For example, if there is a main 3D model named A and a main 3D model named B, and both are listed with a limit value for listing a secondary 3D model named Z, Z is the main 3D model set according to the designs of A and B. According to each attribute value of the model (eg rotation, geometry adjustment, position value, etc.), each is combined differently. Accordingly, even in the secondary 3D model of the same Z, a different combined 3D model is completed according to the attribute values of the main 3D model and the 3D model. Here, the 3D model can be modified in real time through a design transformation tool that can be a sub-element of the reference.

A design transformation tool may have one or more sub-modules.

Each sub-module is capable of unique modification and editing functions such as shape transformation, rotation, color setting, size setting, etc. through a format such as setting variable values for attribute values.

Screenshots are activated when a user 'buys' or a design selection is 'completed' and can be inserted into the order page.

Referring to FIG. 9 , after the main 3D model 801 is expressed on the canvas, it can be output directly with a 3D output device (eg, a 3D printer, etc.). However, after a reference is made into a 3D model, it is used for calculation, but it is not output and is not displayed on the canvas. This is because the reference is later entered into the parser module, only the calculation result remains and the model is deleted.

In the present invention, the shape of the main 3D model can be changed through the design transformation tool. At this time, the price can be calculated in consideration of the volume change due to the shape transformation.

Assuming that the price of the model according to the material is calculated by the material price per unit * the density of the material * the volume per unit in the present invention, the process of calculating the volume of the model after shape deformation will be described as follows.

10 is a view showing a method of calculating a price according to shape deformation according to an embodiment of the present invention.

Referring to FIG. 10 , if the 3D model is put into a finite element region composed of a cuboid (① to ③), the 3D model is sliced into a cuboid in the finite element region (④) At this time, if the boundary surface of the sliced 3D model is enlarged (⑤), it can be divided into the following three cases (⑥)

(a) if the 3D model is completely contained within the finite element domain,

(b) if the 3D model is more than 50% contained within the finite element domain;

(c) the 3D model is contained less than 50% within the finite element domain.

In the present invention, the case of (a) and (b) is included in the volume calculation, and the case of (c) is excluded from the volume calculation.

12 to 18 are examples of screens provided by a custom 3D model design and production system according to an embodiment of the present invention.

The screen example of FIGS. 12 to 18 is a screen provided by a customer-customized 3D model design and production system showing the process of the customer terminal 20 selecting the main 3D model on the web page and combining the secondary 3D model with the reference to pay Yes.

When the primary 3D model 801 is selected in FIG. 12 , it can be seen that a list of secondary 3D models for each reference is displayed on the website.

It can be seen from FIG. 13 that the main 3D model 801 has four references 851 , 852 , 853 , and 854 .

In addition, in FIGS. 13 to 18 , the secondary 3D models 901 , 902 , 903 , 904 are selected and combined for each reference 851 , 852 , 853 , and 854 are sequentially illustrated. And, whenever the secondary 3D model is combined with each socket of the main 3D model, the total amount is immediately displayed, so it can be seen that a website is provided to enable payment.

12 to 18 are screen examples showing a process of selecting a secondary 3D model after selecting a primary 3D model. The primary 3D model may not have a secondary 3D model, or may have two or more secondary 3D models. . Therefore, what corresponds to the setting in the screenshot is the number of references of the primary 3D model and the secondary 3D model. That is, you can see how many secondary models have been set.

The items below the settings show a list that is automatically calculated according to the size attributes that each setting can have. That is, lists according to each calculation may be different for each setting.

In one embodiment of the present invention, it may be provided to select the material value calculation in the product information (Product information) part.

19 and 20 are screen examples illustrating a process of transforming the main 3D model.

As in the screen example of FIG. 19 , it can be seen that an item for inputting variable values for transforming the main 3D model 1801 is provided on the website. When a variable value is entered in this item, as shown in FIG. 20 , a deformed main 3D model 1901 is displayed, and an amount of money for the model can be displayed.

21 to 32 are screen examples showing a process of performing a rendering function.

In the present invention, the rendering function allows the designer terminal 10 to set the rendering value through the rendering value setting unit provided to the website from the server 100 when the designer terminal 10 requests to upload the primary 3D model and the secondary 3D model. In addition, the 3D model (primary 3D model, secondary 3D model) requested to be uploaded through the rendering value set by the designer terminal 10 may be rendered and then uploaded in real time. In addition, in the present invention, the rendering function is implemented so that setting for each material is possible even when a material needs to be different for one model.

21 to 32 , a process of rendering by applying various options such as reflection color, reflection density, material color, luminance, and transparency to the corresponding 3D model is illustrated.

In the present invention, the server 100 may be configured to provide a royalty to the designer terminal 10 that has uploaded the 3D model.

33 is a flowchart illustrating an algorithm for paying royalties to a designer who has uploaded a 3D model to the platform of the server 100 . Here, the platform may be implemented as a website provided by the server 100 .

When the designer terminal 10 accesses the platform of the server 100 (S3201), the platform checks whether the designer terminal 10 requests the 3D model upload (S3203).

When the designer terminal 10 requests to upload the 3D model to the platform of the server 100, the platform inquires whether to agree to providing the 3D model in an open source format to the designer terminal 10 (S3205).

If the designer terminal 10 agrees to provide the 3D model in an open source format, the server 100 uploads the 3D model to the platform and discloses it (S3207).

In this case, when the designer terminal 10 accesses the platform of the server 10 and does not request an additional 3D model upload, the designer terminal 10 checks whether a previously uploaded 3D model exists ( S3209).

The server 100 determines whether the intellectual property right is violated when a report of a violation of intellectual property rights is received on the platform for the 3D model requested by the designer terminal 10 to upload (S3211, Y) (S3213).

At this time, the determination of whether or not the intellectual property rights are violated is determined by the server 100 transmitting the intellectual property right verification request signal to the verification server such as the Korean Intellectual Property Office server, the Intellectual Property Tribunal server, the patent corporation server, the intellectual property right appraisal agency server, and the 3D model of the corresponding 3D model from the verification server. It may consist of receiving judgment information about intellectual property rights violations.

When the server 100 determines that the 3D model violates intellectual property rights from the verification server, the 3D model is deleted (S3217).

However, the server 100 receives data information on intellectual property rights from the verification server, configures a self-verification module in the server 100, and the server 100 determines whether the intellectual property right for the 3D model is violated by itself. And, it may be configured to delete the 3D model according to the judgment information on whether the violation.

On the other hand, if the server 100 does not report a violation of the intellectual property right for the 3D model or if it is determined that it is not a violation of intellectual property rights as a result of the determination (S3215, N), whether the 3D model is used in the design combination of the custom model It is determined whether or not (S3219).

Next, the server 100 increases the combination count (Cc, Combination Count) by 1 when the corresponding 3D model is used for design combination (S3221).

And the server 100 determines whether the custom model in which the 3D model is combined is sold (S3223). When the custom model in which the corresponding 3D model is combined is sold, the sales count (Cs, Sales Count) is incremented by one (S3225).

A count value (C) for each 3D model is determined through the above process, and the count value may be determined as the sum of the combination count and the sales count.

C = Cc + Cs

In this case, the combination count value and the sales count value may be set to simply increase by 1, or may be set in a manner that gives a greater weight to the sales count value than the combination count value.

When the count value (C) for a specific 3D model is determined by the combination count value and the sales count value, the server 100 pays royalties to be paid to the designer terminal 10 who uploaded the 3D model using the determined count value. Calculate (S3227).

For example, subtract all costs (platform management cost, platform usage fee, production cost such as material cost, packaging cost, marketing cost, shipping cost, other operating cost, etc.) from the design product selling price, and add the value to the sum of the count values of all 3D models The royalty can be calculated by multiplying the ratio of the count value of the corresponding 3D model.

The formula for calculating royalties paid is as follows.

(Where n is the number of 3D models combined with the design product, and i is the 3D model subject to payment royalties)

The server 100 is configured to pay the calculated royalty amount to the designer terminal 10 when the royalty payment to be paid to the designer terminal 10 that has uploaded the 3D model is calculated (S3229).

The above description is merely illustrative of the technical spirit of the present invention, and various modifications and variations will be possible without departing from the essential characteristics of the present invention by those skilled in the art to which the present invention pertains. Accordingly, the embodiments disclosed in the present invention are not intended to limit the technical spirit of the present invention, but to explain, and the scope of the technical spirit of the present invention is not limited by these embodiments.
