Description

Technical Field

[0001] This disclosure relates to a method for manufacturing an eye component and a method for manufacturing a three-dimensional object. Background Technology

[0002] There exists a technique for creating a three-dimensional model of a character whose eyes appear to follow the eyes of the person viewing the model.

[0003] Existing technical documents

[0004] Patent documents

[0005] Patent Document 1: Japanese Patent Application Publication No. 2022-074525 Summary of the Invention

[0006] The problem the invention aims to solve

[0007] Patent Document 1 discloses a method for manufacturing an eye component for a facial component assembled into a humanoid body. The method for manufacturing the eye component is characterized by comprising: an iris forming step, which forms an iris portion covering the front surface of the eye component; a pupil forming step, which forms a pupil portion whose front surface is convex and has a protruding portion that protrudes from the rear surface of the iris portion and into the interior of the iris portion; and a base forming step, which forms the base portion in such a way that it contacts the rear surface of the iris portion at the portion where the pupil portion is not formed.

[0008] The degree of tracking ability of the eye component varies depending on the design (position, color, shape, size, etc.) of each component. Therefore, in order to achieve natural tracking, it is necessary to repeatedly prototype while changing the design of each component. On the other hand, the eye component for tracking is manufactured by combining multiple parts or repeatedly molding multiple materials with different colors or materials, so prototyping requires a lot of time.

[0009] Furthermore, in human-themed three-dimensional figures, tracking eye components have been used extensively in many cases. Therefore, a wealth of knowledge and insights has been accumulated regarding the manufacture of tracking eye components for human-themed designs. Consequently, when designing new tracking eye components for human-themed figures, previous designs can be used as references, thus reducing design / prototyping time. On the other hand, when the main character of a three-dimensional figure is a fictional creature, the eye design is sometimes unique. Additionally, the degree to which the viewer perceives tracking varies depending on the position and size relationship of the character's eyes, face, and body. Furthermore, when the main character of a three-dimensional figure is a fictional creature, the position and size relationship of the character's eyes, face, and body is sometimes unique to that character. For these reasons, it is often impossible to use previous knowledge and insights as a reference when designing tracking eye components. Moreover, when the main character of a three-dimensional figure is a fictional creature, the shape of the eyes varies greatly from design to design. Therefore, it is difficult to use previously manufactured eye component designs for other characters as a reference when designing tracking eye components. Furthermore, due to the unique nature of the design, the strength and safety of the manufactured eye components must be carefully verified. For these reasons, when manufacturing eye components themed around fictional creatures, multiple design / prototype iterations are required to establish an appropriate design, necessitating a significant increase in time compared to the case of three-dimensional figures themed around human figures.

[0010] Based on the above reasons, there is a need for an efficient method for manufacturing eye components to be installed on three-dimensional objects.

[0011] The purpose of this disclosure is to efficiently manufacture eye components for installation on three-dimensional objects.

[0012] Solution for solving the problem

[0013] A method for manufacturing an eye component for mounting on a three-dimensional object, the method comprising the following steps: acquiring 3D data of an eye component including an eyeball portion, the eyeball portion including a base and a cover portion, the cover portion being located on one side of the base and at a position covering the base portion, wherein the base includes a pupil portion and a peripheral portion, the pupil portion being disposed on a surface on one side of the base portion, the peripheral portion being located at the periphery of the pupil portion and inclined to one side at a predetermined angle from the pupil portion; generating instruction data based on the 3D data for instructing a 3D printer to shape the eye component; and shaping the eye component by causing the 3D printer to eject shaping material based on the instruction data.

[0027] Hereinafter, an embodiment of the present invention will be described in detail based on the accompanying drawings. Furthermore, in the drawings used to illustrate the embodiment, the same reference numerals are used to label the same constituent elements, and repeated descriptions are omitted.

[0028] <0 Overview of Three-Dimensional Objects>

[0029] Figure 1This is a schematic diagram illustrating the manufacturing process of the three-dimensional object 5 in this embodiment. In this embodiment, the three-dimensional object 5 is a three-dimensional object that imitates a specific fictional creature. Furthermore, the object to be manufactured for the three-dimensional object 5 is not limited to fictional creatures. The three-dimensional object 5 can also be a three-dimensional object that imitates a fictional artifact, a real-life creature, a real-life artifact, etc. Furthermore, in this embodiment, it is not contemplated that the three-dimensional object 5 includes a three-dimensional object that imitates a human.

[0030] Furthermore, in particular, the three-dimensional figurine 5 manufactured in this embodiment is an object that imitates a specific character and is intended to be installed in tourist facilities such as theme parks and amusement parks. The three-dimensional figurine 5 is manufactured, for example, in a way that reproduces the envisioned size. By installing the three-dimensional figurine 5 in tourist facilities, a worldview of a story scenario where the character appears is created within the facility. Additionally, the user experience is enhanced by allowing guests to view the three-dimensional figurine 5 from various angles or to take animated / photographed images of it. Moreover, the location for installing the three-dimensional figurine 5 is not limited to tourist facilities; it can be installed in various locations depending on the purpose.

[0031] like Figure 1 As shown, the three-dimensional object 5 has a main body 6 that imitates the main body of a character and an eye component 7 that imitates the eye of a character.

[0032] The main body 6 has a mounting area 61 for mounting the eye member 7. The mounting area 61 has a recess formed, for example, according to the shape of the eye member 7. For example, when the eye member 7 imitates the eyeball of a character, the mounting area 61 has a recess shaped according to the outline of the character's eyeball. In addition, for example, when the eye member 7 imitates the eyeball and the skin around the eyeball of a character, the mounting area 61 has a recess shaped according to the outline of the skin imitated by the eye member 7. The eye member 7 is mounted to the mounting area 61 by being embedded in the recess of the mounting area 61. When the eye member 7 is embedded in the recess, the eye member 7 can be fixed to the mounting area 61 by methods such as embedding, bolt and nut fixing, welding, or adhesive bonding.

[0033] use Figure 1 The manufacturing process of the three-dimensional object 5 will be explained below. First, the main body 6 is manufactured using any modeling method. Next, eye components 7 are manufactured using a 3D printer. Furthermore, the three-dimensional object 5 is manufactured by installing the eye components 7 into the mounting area 61 of the main body 6. When installing the eye components 7 into the mounting area 61, surface finishing processes such as grinding, painting, or embedding fillers can be performed on the boundary between the mounting area 61 and the eye components 7. As a result, the boundary between the mounting area 61 and the eye components 7 becomes inconspicuous.

[0034] In this embodiment, the main body 6 is manufactured, for example, using FRP (Fiber Reinforced Plastics). However, the material of the main body 6 is not limited to FRP. The material of the main body 6 can also be metals such as iron and steel, resins such as polyurethane and acrylic, wood, etc. Additionally, in this embodiment, the eye member 7 is manufactured, for example, using acrylic resin. However, the material of the eye member 7 is not limited to this. The material of the eye member 7 can also be natural resin, synthetic resin, plaster, metal powder, etc.

[0035] <0.1 Details of the eye component>

[0036] Figure 2 This is a front view of the eye component 7 manufactured in this embodiment. Figure 3 This is a cross-sectional view of the eye component 7 manufactured in this embodiment. Figure 4 Other examples are the AA section diagrams of eye member 7. Figure 5 These are other examples of the AA section view of eye member 7. For example... Figure 2 As shown, the eye component 7 has an eyeball portion 71 and a main body region 72. Alternatively, the eye component 7 may not have a main body region 72.

[0037] Section 71, the eyeball section, is the part that mimics the character's eyeball. For example... Figure 3 As shown, the eyeball portion 71 has a base 711 and a covering portion 712.

[0038] The base 711 is the part that forms the basis of the eyeball portion 71. For example... Figure 3 As shown, the base 711 has a pupil portion 7111 and a peripheral portion 7112.

[0039] The pupil section 7111 is the part that mimics the pupil of a character's eye. For example... Figure 3 As shown, the pupil portion 7111 is disposed on one side of the base 711 at the center of the base 711. Alternatively, the pupil portion 7111 may not be disposed at the center of the base 711. Figure 3 As shown, the pupil portion 7111 has, for example, a planar shape. Furthermore, as... Figure 4 As shown, the pupil portion 7111 can also have a curved shape. The curved shape of the pupil portion 7111 can be, for example,... Figure 4 The convex shape shown can also be a concave shape or other shapes. Additionally, as... Figure 5As shown, the pupil portion 7111 can also refer to the vertex of the angle formed by the peripheral portion 7112 in the base 711. The degree of tracking of the eye component 7 varies depending on parameters such as the position of the pupil portion 7111 (especially the position of the peripheral portion 7112 and the covering portion 712 relative to the first surface 7121), color, shape, and size. Therefore, the designer of the eye component 7 adjusts parameters such as the position of the pupil portion 7111 (especially the position of the peripheral portion 7112 and the covering portion 712 relative to the first surface 7121), color, shape, and size in order to achieve appropriate tracking for the character being modeled.

[0040] The peripheral portion 7112 is a part that mimics the periphery of a character's pupil. For example, the peripheral portion 7112 can also represent the iris of a character's eyeball. The peripheral portion 7112 is located around the periphery of the pupil portion 7111 and is set to be tilted to one side at a predetermined angle relative to the pupil portion 7111. The degree of tracking of the eye component 7 varies depending on parameters such as the position, color, shape, and size of the peripheral portion 7112 (especially the tilt angle relative to the pupil portion 7111). Therefore, the designer of the eye component 7 adjusts the color, shape, and size of the peripheral portion 7112 (especially the tilt angle relative to the pupil portion 7111) to achieve appropriate tracking for the character being modeled.

[0041] The pupil portion 7111 and the peripheral portion 7112 are made of materials with different appearances. Here, "different appearances" means, for example, a difference in appearance due to differences in at least one of the following: material, color, or transparency. This creates a difference in appearance between the pupil portion and the peripheral portion of the pupil in the character's eyeball.

[0042] Alternatively, the base 711 may have a portion on the periphery of the peripheral portion 7112 that has a different appearance from the peripheral portion 7112. This portion may, for example, represent the whites of a character's eyes.

[0043] The covering portion 712 is a part that mimics the surface (cornea) of a character's eyeball. For example... Figure 3 As shown, the cover 712 is located on one side of the base 711 and covers the base 711. The cover 712 is made of a light-transmitting material. Thus, as... Figure 2 As shown, when viewing the eye member 7 from one side of the cover 712, the appearance of the pupil portion 7111 and the peripheral portion 7112 can also be visually confirmed through the cover 712.

[0044] In addition, such as Figure 3As shown, the cover 712 has a first surface 7121 that is exposed to the outside and does not contact the pupil 7111, and a second surface 7122 that is not exposed to the outside and contacts the pupil 7111. The first surface 7121 has a curved shape. The degree of tracking of the eye member 7 varies depending on parameters such as the position, color, shape (especially the distance between the first surface 7121 and the pupil 7111), and size (especially the size and curvature of the first surface 7121) of the cover 712. Therefore, the designer of the eye member 7 adjusts parameters such as the position, color, shape (especially the distance between the first surface 7121 and the pupil 7111), and size (especially the size and curvature of the first surface 7121) of the cover 712 in order to achieve appropriate tracking for the character of the model.

[0045] Furthermore, the second surface 7122 may not be in contact with the pupil portion 7111. In this case, the area between the second surface 7122 and the pupil portion 7111 may be filled with a light-transmitting material or may be empty.

[0046] like Figures 3-5 As shown, by positioning the pupil portion 7111 at a predetermined distance from the first surface 7121 of the covering portion 712 on the opposite side of the first surface 7121 of the covering portion 712, the pupil portion 7111 can appear to follow (track) the person viewing the eye member 7. As described above, the degree of tracking by the eye member 7 varies depending on parameters such as the position, color, shape, and size of the pupil portion 7111, the peripheral portion 7112, and the covering portion 712 (including the first surface 7121 and the second surface 7122). Therefore, in order to achieve appropriate tracking for the character of the model, these parameters need to be adjusted. Consequently, in order to achieve appropriate tracking for the character of the model, it is necessary to repeatedly design and prototype the eye member 7 while adjusting these parameters.

[0047] The main area 72 is a section that mimics the skin around the character's eyes. For example... Figure 2 and Figure 3 As shown, the main body region 72 is positioned to contact the eyeball portion 71. Additionally, as... Figure 2 As shown, the main body region 72 is configured to surround the eyeball portion 71. The main body region 72 is made of a material with an appearance similar to that of the mounting area 61 of the main body portion 6. As a result, when the eye component 7 is mounted in the mounting area 61, the boundary between the main body portion 6 and the eye component 7 is inconspicuous, giving the three-dimensional object 5 a natural appearance.

[0048] <1 System Overall Structure Diagram>

[0049] Figure 6 This is a block diagram illustrating an example of the overall structure of System 1. Figure 6The system 1 shown includes, for example, a terminal device 10 and a 3D printer 30. The terminal device 10 and the 3D printer 30 are connected, for example, via a network 80.

[0050] Figure 6 The terminal device 10 shown can be implemented, for example, as a stationary PC (Personal Computer) or a laptop PC. Alternatively, the terminal device 10 can also be implemented, for example, as a smartphone, tablet computer, or other portable terminal that supports mobile communication systems. Furthermore, the terminal device 10 can also be implemented, for example, as a wearable terminal such as an HMD (Head Mount Display).

[0051] Terminal device 10 includes a communication interface 12, an input device 13, an output device 14, a memory 15, a storage device 16, and a processor 19. The input device 13 is a device for accepting input operations from the user (e.g., mouse, keyboard, etc.). The output device 14 is a device for presenting information to the user (display, speaker, etc.).

[0052] Terminal device 10 comprises a computer equipped with a computing unit and a storage unit. The basic hardware structure of the computer and the basic functional structure of the computer implemented through this hardware structure will be described later. Regarding terminal device 10, descriptions that overlap with the later descriptions of the basic hardware structure and basic functional structure of the computer will be omitted.

[0053] The 3D printer 30 is a molding device that shapes the eye component 7 based on information sent from the terminal device 10. The 3D printer 30 shapes the eye component 7 using molding materials appropriate to each method, such as material extrusion, light modeling, or inkjet printing. The 3D printer 30 includes, for example, an ejector section for ejecting molding materials and a platform for stacking the ejected molding materials. Furthermore, in this embodiment, the ejector section of the 3D printer 30 can switch between ejecting multiple different molding materials. In addition, the 3D printer 30 can also shape the main body 6 in any manner.

[0054] <Structure of Terminal Device>

[0055] Figure 7 It means Figure 6 A block diagram illustrating an example structure of the terminal device 10. (As shown...) Figure 7 As shown, the terminal device 10 includes a communication unit 120, an input device 13, an output device 14, a sound processing unit 17, a microphone 171, a speaker 172, a position information sensor 150, a camera 160, a motion sensor 170, a storage unit 180, and a control unit 190. The modules included in the terminal device 10 are electrically connected, for example, via a bus.

[0056] The communication unit 120 performs modulation and demodulation processing for communication between the terminal device 10 and other devices. The communication unit 120 performs transmission processing on signals generated by the control unit 190 and transmits them to an external source (e.g., a server). The communication unit 120 performs reception processing on signals received from an external source and outputs them to the control unit 190.

[0057] Input device 13 is a device for users to input instructions or information when operating terminal device 10. Input device 13 is implemented, for example, by a reader, keyboard 131, mouse 132, etc. In the case that terminal device 10 is a smartphone, the input device may also be implemented by a touch-sensitive device that inputs instructions by touching the operating surface. Input device 13 converts the instructions input by the user into electrical signals and outputs the electrical signals to control unit 190. In addition, input device 13 may also include, for example, a receiving port for receiving electrical signals input from external input devices.

[0058] Output device 14 is a device for presenting information to the user of operating terminal device 10. Output device 14 is implemented, for example, by display 141. Display 141 displays data corresponding to the control of control unit 190. Display 141 is implemented, for example, by LCD (Liquid Crystal Display) or organic EL (Electro-Luminescence) display.

[0059] The sound processing unit 17 performs, for example, digital-to-analog conversion of the sound signal. The sound processing unit 17 converts the signal provided from the microphone 171 into a digital signal and provides the converted signal to the control unit 190. Additionally, the sound processing unit 17 provides the sound signal to the speaker 172. The sound processing unit 17 is implemented, for example, by a processor for sound processing. The microphone 171 receives sound input and provides the sound signal corresponding to that sound input to the sound processing unit 17. The speaker 172 converts the sound signal provided from the sound processing unit 17 into sound and outputs the sound to the outside of the terminal device 10.

[0060] The location information sensor 150 is a sensor that detects the location of the terminal device 10, such as a GPS (Global Positioning System) module. A GPS module is a receiving device used in a satellite positioning system. In a satellite positioning system, signals from at least three or four satellites are received, and the current location of the terminal device 10 equipped with the GPS module is detected based on the received signals. The location information sensor 150 can also detect the current location of the terminal device 10 based on the location of the wireless base station to which the terminal device 10 is connected.

[0061] The storage unit 180 is implemented, for example, by a memory 15 and a storage device 16, and is used to store data and programs used by the terminal device 10. The storage unit 180 stores, for example, 3D data 183 and instruction data 184.

[0062] 3D data 183 is data relating to a 3D object that represents the shape of the eye component 7 in 3D. 3D data 183 is stored in storage unit 180 in any form, such as an .obj file. 3D data 183 may also contain data relating to the 3D object of the main body 6.

[0063] In 3D data 183, the 3D object of the eye component 7 is formed in a manner that allows for the differentiation of 3D objects of each part included in the eye component 7. For example, the 3D object of the eye component 7 is formed in a manner that allows for the differentiation of the 3D object of the eyeball portion 71 and the 3D object of the main body region 72. Furthermore, for example, the 3D object of the eyeball portion 71 is formed in a manner that allows for the differentiation of the 3D object of the base 711 and the 3D object of the covering portion 712. Additionally, for example, the 3D object of the base 711 is formed in a manner that allows for the differentiation of the 3D object of the pupil portion 7111 and the 3D object of the peripheral portion 7112.

[0064] 3D data 183 includes information related to the 3D object involved in 3D data 183, namely object information 1831. In addition, 3D data 183 may not include some or all of the information contained in object information 1831, and some or all of the information contained in object information 1831 may be stored in storage unit 180 in association with 3D data 183.

[0065] Figure 8 This is a diagram illustrating an example of the data structure for object information 1831. Furthermore, Figure 8 This is one example, and does not exclude unrecorded data. Object information 1831 includes the item "Object ID", item "Object Name", item "Coordinates", and item "Texture Information".

[0066] The "Object ID" item stores the object ID used to identify objects. For example, the object ID identifies the 3D object of the eye component 7, as well as the 3D objects of each part of the eye component 7 (eyeball 71, main body region 72, base 711, covering 712, pupil 7111, and peripheral region 7112). In the 3D data 183, when a defined 3D object (main object) includes other 3D objects (sub-objects), the object ID of the main object and the object ID of the sub-objects can be associated with each other through group structures, hierarchical structures, etc. For example, in this embodiment, the object ID of the 3D object of the eye component 7 can be associated with the object ID of the 3D object of the eyeball 71 and the object ID of the 3D object of the main body region 72.

[0067] The "object name" item is the item that stores the name of the object.

[0068] Specifically, the "object name" field stores the name of a defined part of a modeling object that corresponds to a 3D object identified by its object ID. For example, the "object name" field stores the names of the base 711, cover 712, etc., included in the eye component 7.

[0069] The "Coordinates" item is a value that stores the coordinates representing the position of a 3D object.

[0070] Specifically, the "coordinates" item stores the values ​​of the x, y, and z coordinates of a 3D object. For example, the "coordinates" item stores the coordinates of the center of a 3D object.

[0071] The "Texture Information" project is a project that stores texture information related to the texture of a 3D object.

[0072] Specifically, the "Texture Information" item stores information related to the visual effects applied to the surface of a 3D object. For example, the "Texture Information" item stores information related to the color, gloss, roughness, and transparency of the 3D object's surface.

[0073] Instruction data 184 is data that records the action commands used to instruct the 3D printer 30 to shape the eye component 7. Specifically, instruction data 184 includes information related to any setting items corresponding to the shaping method of the 3D printer 30. For example, instruction data 184 includes information related to the setting of the movement path of the ejector section of the 3D printer 30, information related to the control settings of the ejector section, and information related to the settings for curing the ejected modeling material (temperature setting, light irradiation setting, etc.). Instruction data 184 is represented, for example, by G-code.

[0074] The control unit 190 reads the program stored in the storage unit 180 through the processor 19 and executes the commands contained in the program. The control unit 190 controls the operation of the terminal device 10. By performing actions according to the program, the control unit 190 performs the functions of the operation receiving unit 191, the transceiver unit 192, the presentation control unit 193, and the instruction data generation unit 194.

[0075] The operation receiving unit 191 processes instructions or information input from the input device 13. For example, the operation receiving unit 191 receives instructions or information input from the keyboard 131, mouse 132, etc.

[0076] In addition, the operation receiving unit 191 receives audio information input from the microphone 171. Specifically, for example, the operation receiving unit 191 receives audio data input from the microphone 171 and converted into digital data by the audio processing unit 17.

[0077] The transceiver unit 192 processes data for the terminal device 10 to send and receive data with external devices according to the communication protocol.

[0078] The presentation control unit 193 controls the output device 14 and the like to present information provided to the user by the execution of the program stored in the storage unit 180, information provided to the user from the 3D printer 30, and other information.

[0079] The instruction data generation unit 194 generates instruction data 184 based on 3D data 183. Specifically, the instruction data generation unit 194 slices the 3D object of the eye member 7 involved in the 3D data 183 along a predetermined plane (e.g., the xy plane defined in the 3D data 183) into multiple layers that overlap in a direction perpendicular to the predetermined plane (e.g., the z-axis direction defined in the 3D data 183), and outputs instruction data 184 containing the action commands of the 3D printer 30 for shaping the multiple layers.

[0080] <Action>

[0081] (Instructions for data generation and processing)

[0082] The instruction data generation process of this embodiment will be described. The instruction data generation process is a process of generating instruction data 184 based on 3D data 183. Figure 9 This is a flowchart of the instruction data generation process in this embodiment.

[0083] Beforehand, the user models the eye component 7 using prescribed modeling software, creating 3D data 183. At this time, the position, shape, and size of the pupil portion 7111, the tilt angle of the peripheral portion 7112, and the shape of the covering portion 712 included in the eye component 7 are designed so that the pupil portion 7111 appears to follow the viewer of the stereoscopic object 5. Thus, the stereoscopic object 5 with the eye component 7 appears to follow the viewer of the stereoscopic object 5. The user stores the created 3D data 183 in the storage unit 180 of the terminal device 10 beforehand.

[0084] In step S101, the terminal device 10 acquires 3D data 183 from the storage unit 180.

[0085] Specifically, the terminal device 10 obtains 3D data 183 from the storage unit 180 by accepting user operations. The terminal device 10 launches a specified application (e.g., any slicing software) to read in the 3D data 183.

[0086] In step S102, the terminal device 10 presents a settings UI related to the generation of instruction data 184 to the user. Specifically, the terminal device 10 generates the settings UI based on the 3D data 183 read in step S101 and presents it to the user via the display 141.

[0087] The UI settings include areas for displaying the 3D object of the eye component 7 and the 3D objects of the various parts included in the eye component 7.

[0088] Additionally, the UI settings include an area for displaying styling settings for each object ID in the object information 1831. The terminal device 10, for example, refers to each record in the object information 1831 to display an area for inputting settings for each object ID. Examples of settings include the following items.

[0089] (Settings related to slicing 3D data)

[0090] • Number of slices

[0091] • Spacing of slices

[0092] (Settings related to the configuration of the model on the platform of 3D printer 30)

[0093] • The location of the sculptures on the platform

[0094] • The size of the sculptures on the platform

[0095] • The orientation of the objects on the platform

[0096] (Settings related to modeling materials)

[0097] • Specify the materials used in the design (color, transparency, texture, type, etc.)

[0098] (Settings related to the operation of 3D printer 30)

[0099] • Speed ​​of ejection section

[0100] • Action path of the ejector section

[0101] • Supply of modeling materials

[0102] • Spraying temperature of the molding material

[0103] • Settings related to the curing of the modeling material (cooling temperature of the modeling material, settings for the light irradiating the modeling material (irradiation time, irradiation wavelength, etc.)).

[0104] Users input information to configure settings related to the shape of the eye component 7 by entering information for each setting item displayed in the setting UI. Furthermore, in the setting UI, for specified setting items, information can be entered by each object ID, by any number of object IDs, or by all object IDs together. In particular, the colors and materials of the styling materials used for the various parts included in the eye component 7 (eyeball 71, main body region 72, base 711 and covering 712 included in the eyeball 71, pupil 7111 and peripheral 7112 included in the base 711) may differ. In this case, the terminal device 10 accepts input of setting items individually for each object ID corresponding to each part included in the eye component 7. For example, the terminal device 10 can accept information input for setting items based on the object IDs corresponding to the covering portion 712, the peripheral portion 7112, and the pupil portion 7111, respectively, thereby assigning different settings to the portions of the 3D data 183 corresponding to the covering portion 712, the peripheral portion 7112, and the pupil portion 7111, respectively. Alternatively, the terminal device 10 can also accept information input for setting items based on the object IDs corresponding to the covering portion 712 and the main body area 72, respectively, thereby assigning different settings to the portions of the 3D data 183 corresponding to the covering portion 712 and the main body area 72, respectively.

[0105] Additionally, the UI is configured to include an area for displaying buttons for accepting input of instructions to generate instruction data 184. When the buttons accept input from the user, the terminal device 10 proceeds to step S103.

[0106] In step S103, the terminal device 10 accepts settings related to the shape of the eye component 7.

[0107] Specifically, the terminal device 10 accepts information input by the user for each setting item in the setting UI presented in step S102. Furthermore, the terminal device 10 can also automatically set the modeling based on information stored in each item of the object information 1831, without accepting input from the user. For example, the terminal device 10 can also allocate settings for the modeling material (e.g., settings related to the color of the modeling material) when modeling the 3D object involved in the record based on texture information (e.g., color-related information) stored in the "texture information" item in the specified record of the object information 1831.

[0108] The terminal device 10 slices the 3D object of the eye component 7 based on information received from the user regarding each setting item. Specifically, the terminal device 10 slices the 3D object of the eye component 7, which is set to be in the position, size, and orientation received from the user, into multiple layers according to the slicing intervals received from the user. In addition, the terminal device 10 determines the operation content of the 3D printer 30 for modeling each layer obtained from the slices (setting of the movement path of the ejector, setting of the ejector control, setting for curing the ejected modeling material, etc.) based on information received from the user regarding each setting item.

[0109] In step S104, the terminal device 10 generates instruction data 184 based on the slicing results. Specifically, the terminal device 10 converts the actions of the 3D printer 30 determined in step S103 into instruction data 184 that the 3D printer 30 can execute. For example, the terminal device 10 generates instruction data 184 by converting information such as the movement path of the ejector section, the control settings of the ejector section, and the temperature settings of the 3D printer 30 determined in step S103 into G-code. The terminal device 10 stores the generated instruction data 184 in the storage unit 180.

[0110] (Styling)

[0111] The shaping process of this embodiment will be explained. The shaping process is based on the instruction data 184 to shape the eye component 7. Figure 10 This is a flowchart of the modeling process in this embodiment.

[0112] First, the terminal device 10 executes an application for controlling the 3D printer 30 based on the user's operation.

[0113] In step S201, the terminal device 10 instructs the 3D printer 30 to shape the eye component 7 by sending instruction data 184 related to the eye component 7 to the 3D printer 30.

[0114] Specifically, the terminal device 10 retrieves the instruction data 184 related to the eye component 7 from the storage unit 180 based on the user's operation and sends it to the 3D printer 30.

[0115] In step S202, the 3D printer 30 shapes the eye component 7 based on the instruction data 184 received from the terminal device 10.

[0116] Specifically, the 3D printer 30 reads the instruction data 184 received from the terminal device 10 and, according to the commands described in the instruction data 184, ejects molding material from its ejector section, layering the molding material onto a platform. Then, the 3D printer 30, according to the commands described in the instruction data 184, solidifies the layered molding material on the platform to create the eye component 7. The molding material used for shaping is, for example, acrylic resin, but any molding material can be used according to the instruction data 184.

[0117] Furthermore, in step S202, the 3D printer 30, according to the settings set in step S102 of the instruction data generation process, alternately ejects modeling materials allocated to each part of the eye component 7, thereby modeling each part of the eye component 7 using different modeling materials. For example, the cover portion 712 and the base portion 711 of the eye component 7 are modeled using modeling materials with different appearances. Additionally, for example, the pupil portion 7111 and the peripheral portion 7112 in the base 711 are modeled using modeling materials with different appearances. Furthermore, for example, the eyeball portion 71 and the main body region 72 are modeled using modeling materials with different appearances. Thus, the appearance features of the character being modeled can be reproduced well.

[0118] Furthermore, in this embodiment, it is not necessary to manufacture parts made of different materials separately in different processes; the eye components can be manufactured together in one process. Therefore, the eye components can be manufactured efficiently.

[0119] Furthermore, in this embodiment, eye components comprising multiple parts made of different materials can be manufactured efficiently and simultaneously, allowing for rapid design changes to each component of the eye component. This enables the rapid prototyping of multiple design schemes. Consequently, research into designs for achieving appropriate tracking of the eye component can be conducted efficiently.

[0120] As described above, the eye component 7 is manufactured through instruction data generation processing and shaping processing. In the manufactured eye component 7, the base 711 and the cover 712 are formed of materials with different appearances. On the other hand, as in step S202 of the shaping processing, the base 711 and the cover 712 are formed into one piece in a single process. Furthermore, in the manufactured eye component 7, the eyeball portion 71 and the main body region 72 are formed of materials with different appearances. On the other hand, as in step S202 of the shaping processing, the eyeball portion 71 and the main body region 72 are formed into one piece in a single process.

[0121] Furthermore, the eye component 7, which is manufactured through instruction data generation processing and modeling processing, is installed in the mounting area 61 of the main body 6, which is shaped by any modeling method, thereby creating a three-dimensional model 5 with an eye component capable of tracking.

[0122] <Summary>

[0123] In the manufacturing method described above, 3D data of an eye component 7, including an eyeball portion 71, is acquired. The eyeball portion 71 includes a base 711 and a cover portion 712. The cover portion 712 is located on one side of the base 711 and covers the base 711. The base 711 includes a pupil portion 7111 and a peripheral portion 7112. The pupil portion 7111 is disposed on one side of the base 711, and the peripheral portion 7112 is located at the periphery of the pupil portion 7111 and is inclined to one side at a predetermined angle from the pupil portion 7111. Furthermore, in the manufacturing method described above, instruction data for instructing a 3D printer to shape the eye component 7 is generated based on the 3D data. Additionally, in the manufacturing method described above, the eye component 7 is shaped by ejecting shaping material from the 3D printer based on the instruction data. Therefore, it is possible to efficiently manufacture an eye component 7 for mounting on a three-dimensional object 5.

[0124] In the manufacturing method described above, different settings can be assigned to the portions in the 3D data corresponding to the covering portion 712, the portion corresponding to the pupil portion 7111, and the portion corresponding to the peripheral portion 7112, and the molding material can be sprayed based on the settings assigned in the step of generating instruction data. This allows for the efficient manufacturing of an eye component 7 that includes multiple portions with different molding settings in a single process.

[0125] In the manufacturing method described above, the position, shape, and size of the pupil portion 7111, the tilt angle of the peripheral portion 7112, and the shape of the covering portion 712 included in the eye component 7 can be designed so that the pupil portion 7111 behaves as if following a person viewing the three-dimensional object 5. This allows for the efficient manufacture of the eye component 7 for tracking.

[0126] In the manufacturing method described above, the eye component 7 may also include a main body region 72 that contacts the eyeball portion 71. Different settings are assigned to the portions in the 3D data corresponding to the covering portion 712 and the portions corresponding to the main body region 72, and styling material is sprayed out based on the assigned settings. Thus, it is possible to efficiently manufacture the eye component 7, which includes multiple portions with different styling settings, all at once.

[0127] Alternatively, as explained above, the three-dimensional object 5 can also be manufactured by installing the manufactured eye component 7 into the corresponding mounting area 61. This allows for the efficient manufacture of a three-dimensional object 5 equipped with the eye component 7.

[0128] Alternatively, as explained above, the eye component 7 can also be manufactured through a process including the following steps: acquiring 3D data of the eye component 7, which includes an eyeball portion 71 comprising a base 711 and a cover portion 712, the cover portion 712 being located on one side of the base 711 and covering the base 711, wherein the base 711 includes a pupil portion 7111 and a peripheral portion 7112, the pupil portion 7111 being disposed on one side of the base 711, and the peripheral portion 7112 being located on the periphery of the pupil portion 7111 and tilted to one side at a predetermined angle from the pupil portion 7111; generating instruction data based on the 3D data to instruct a 3D printer to shape the eye component 7; and shaping the eye component 7 by having the 3D printer eject shaping material based on the instruction data. Thus, the eye component 7 for mounting on a three-dimensional object 5 can be manufactured efficiently.

[0129] Furthermore, as explained above, the three-dimensional object 5 can also have eye components 7. Therefore, it is possible to efficiently manufacture a three-dimensional object 5 equipped with eye components 7.

[0130] Alternatively, as explained above, the eye member 7 may have an eyeball that mimics an eyeball. The eyeball portion 71 has a base 711 and a cover 712 located on one side of the base 711 and covering the base 711. The base 711 has a pupil portion 7111 located on one side of the base 711 and a peripheral portion 7112 located at the periphery of the pupil portion 7111 and inclined to one side at a predetermined angle from the pupil portion 7111. The base 711 and the cover 712 are formed of different materials and are integrally formed. Thus, the eye member 7 is integrally formed instead of combining separate parts, making the processing of the eye member 7 easier compared to the case where they are separate parts. Furthermore, the strength of the eye member 7 is increased.

[0131] Alternatively, as explained above, the eye component 7 may have a main body region 72 that contacts the eyeball portion 71 and mimics the surrounding portion of the eyeball. The eyeball portion 71 and the main body region 72 may be formed from materials with different appearances, and the eyeball portion 71 and the main body region 72 may be formed as a single unit. Thus, the eye component 7 is formed as a single unit instead of combining individual parts, making the processing of the eye component 7 easier compared to the case where they are separate parts. Furthermore, the strength of the eye component 7 is increased.

[0132] Furthermore, as explained above, the three-dimensional object 5 can also have an eye component 7. Therefore, instead of assembling separate parts, the eye component 7 is formed as a single piece, making its processing easier compared to the case where it is divided into separate parts. In addition, the strength of the eye component 7 is increased.
