DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. The present disclosure is not limited to the following embodiments. In the following drawings, identical parts are designated by the same reference numerals. Furthermore, the descriptions of the embodiments can be used interchangeably unless otherwise specified, and the configurations of the embodiments can be combined unless otherwise specified. In the present disclosure, each drawing may apply to one or more embodiments.

[0016] In the present disclosure, the "target structure" is not particularly limited as long as it is, for example, a structure formed by combining multiple materials. The target structure may be, for example, a building or a structure other than a building. When the target structure is a building, the basic structure of the building may be, for example, wooden, steel-framed, or some other structure.

[0017] [Embodiment 1] The three-dimensional image generation support program of the present disclosure is a program for causing a computer to execute a three-dimensional image generation procedure, a correction information acquisition procedure, an affected area identification procedure, and an image correction procedure. The three-dimensional image generation support program of the present disclosure can also be said to be a program for causing a computer to function as the three-dimensional image generation procedure, the correction information acquisition procedure, the affected area identification procedure, and the image correction procedure. Furthermore, the three-dimensional image generation support program of the present disclosure can also be said to be a program for causing a computer to execute, for example, each step of the three-dimensional image generation support method described below.

[0018] The three-dimensional image generating step generates a three-dimensional image based on CAD information; The CAD information includes material information of the target structure and connection information between the materials, the correction information acquisition step acquires correction information of the target structure; The correction information includes identification information of the correction target material and material information after correction of the correction target material, The step of identifying an influence range includes identifying an influence range in which the correction target material affects the target structure based on the CAD information and the correction information, The image correction procedure corrects the three-dimensional image based on the CAD information, the correction information, and the range of influence.

[0019] For example, the "procedure" in each step can be read as a "process." The three-dimensional image generation assistance program of the present disclosure may be recorded on a computer-readable recording medium.

The three-dimensional image generation assistance program of the present disclosure (also referred to as a programming product or program product) may be distributed from an external computer. The "distribution" may be, for example, distribution via a communication network or a device connected via a wire. The 3D image generation support program of the present disclosure may be installed and executed on the device to which it is distributed, or may be executed without being installed. An information processing device capable of executing the 3D image generation support program of the present disclosure can be referred to as, for example, the 3D image generation support device of the present disclosure.

[0020] Next, the configuration of an example of a 3D image generation support device according to the present disclosure will be described with reference to FIG. 1. FIG. 1 is a block diagram showing an example of the configuration of a 3D image generation support device 10 according to the present disclosure (hereinafter also referred to as the present device 10). As shown in FIG. 1, the present device 10 includes a 3D image generation unit 11, a correction information acquisition unit 12, an affected area identification unit 13, and an image correction unit 14. Although not shown, the present device 10 may also include, for example, an input unit, an output unit, a display unit, and / or a storage unit. The 3D image generation unit 11, the correction information acquisition unit 12, the affected area identification unit 13, and the image correction unit 14 are capable of executing, for example, a 3D image generation procedure, a correction information acquisition procedure, an affected area identification procedure, and an image correction procedure in the 3D image generation support program according to the present disclosure, respectively.

[0021] The device 10 may be, for example, a single device including the above-described units, or a device in which the units can be connected via a communication network. The device 10 can also be connected to an external device (described later) via the communication network. The communication network is not particularly limited and any known network can be used, for example, a wired or wireless network. Examples of the communication network include the Internet, the World Wide Web (WWW), a telephone line, a Local Area Network (LAN), a Storage Area Network (SAN), a Delay Tolerant Networking (DTN), a Low Power Wide Area Network (LPWA), and a Local 5G (L5G). Examples of wireless communication include Wi-Fi (registered trademark), Bluetooth (registered trademark), Local 5G, and LPWA. Examples of the wireless communication include direct communication between devices (Ad Hoc communication), infrastructure communication, and indirect communication via an access point. The device 10 may be incorporated into a server as a system. Furthermore, the present device 10 may be, for example, a personal computer (PC, for example, desktop or notebook type) on which the program of the present disclosure is installed, a smartphone, a tablet terminal, etc. The present device 10 may be in the form of cloud computing or edge computing, for example, in which at least one of the above-mentioned units is located on a server and the other units are located on a terminal.

[0022] 2 shows a block diagram of the hardware configuration of the device 10. The device 10 includes, for example, a central processing unit (CPU, GPU, etc.) 101, a memory 102, a bus 103, a storage device 104, an input device 105, an output device 106, and a communication device 107. The components of the device 10 are connected to each other via the bus 103 and their respective interfaces (I / F).

[0023] The central processing unit 101 cooperates with other components via a controller (such as a system controller or an I / O controller) and is responsible for overall control of the device 10. In the device 10, the central processing unit 101 executes, for example, the program of the present disclosure (the three-dimensional image generation assistance program) and other programs, and also reads and writes various types of information. Specifically, for example, the central processing unit 101 functions as a three-dimensional image generation unit 11, a correction information acquisition unit 12, an affected area identification unit 13, and an image correction unit 14. The device 10 may include other calculation units such as a CPU, a GPU (Graphics Processing Unit), an APU (Accelerated Processing Unit), or a combination thereof as a calculation unit.

[0024] The bus 103 can also be connected to, for example, external devices. Examples of the external devices include an external storage device (such as an external database), a printer, an external input device, an external display device, and an external imaging device. The device 10 can be connected to an external network (the communication line network) by, for example, a communication device 107 connected to the bus 103, and can also be connected to other devices via the external network.

[0025] The memory 102 may be, for example, a main memory (primary storage device). When the central processing unit 101 performs processing, the memory 102 reads various operating programs, such as the program of the present disclosure, stored in the storage device 104 (described later), and the central processing unit 101 receives data from the memory 102 and executes the programs. The main memory may be, for example, a RAM (random access memory). The memory 102 may also be, for example, a ROM (read only memory).

[0026] The storage device 104 is also referred to as an auxiliary storage device, for example, in contrast to the main memory (primary storage device). As described above, the storage device 104 stores an operating program including the program of the present disclosure. The storage device 104 may be, for example, a combination of a recording medium and a drive for reading and writing data from and to the recording medium. The recording medium is not particularly limited and may be, for example, an internal or external type, such as a hard disk (HD), CD-ROM, CD-R, CD-RW, MO, DVD, flash memory, or memory card. The storage device 104 may be, for example, a hard disk drive (HDD) or a solid state drive (SSD) in which the recording medium and drive are integrated. When the device 10 includes the storage unit, for example, the storage device 104 functions as the storage unit. The storage unit may store, for example, a recalculation list, which will be described later.

[0027] In the present device 10, the memory 102 and the storage device 104 can also store various information such as log information, information acquired from an external database (not shown) or an external device, information generated by the present device 10, and information used when the present device 10 executes processing. In this case, the memory 102 and the storage device 104 may store, for example, the above-mentioned information on the user of the present device. Note that at least a portion of the information may be stored, for example, in an external server other than the memory 102 and the storage device 104, or may be stored in a distributed manner across multiple terminals using blockchain technology or the like.

[0028] The device 10 further includes, for example, an input device 105 and an output device 106. Examples of the input device 105 include pointing devices such as a touch panel, track pad, and mouse; a keyboard; imaging means such as a camera and scanner; card readers such as an IC card reader and a magnetic card reader; and audio input means such as a microphone. Examples of the output device 106 include display devices such as an LED display and a liquid crystal display; audio output devices such as a speaker; a printer; and the like. In the first embodiment, the input device 105 and the output device 106 are configured separately, but the input device 105 and the output device 106 may be configured as an integrated device, such as a touch panel display.

[0029] An example of processing by the three-dimensional image generation support program of the present disclosure will be described more specifically with reference to Fig. 3. Fig. 3 is a flowchart showing an example of each procedure of the three-dimensional image generation support program of the present disclosure.

[0030] The three-dimensional image generating unit 11 generates a three-dimensional image based on CAD information (S1, three-dimensional image generating procedure). The CAD information includes material information of the target structure and connection information between the materials. The CAD information may be, for example, two-dimensional CAD project data or drawing data input into CAD software. The three-dimensional image generating unit 11 may, for example, acquire CAD information input into the device 10 by a user to generate the three-dimensional image, or may acquire CAD information from other CAD software to generate the three-dimensional image. The three-dimensional image generating unit 11 can generate the three-dimensional image, for example, using a three-dimensional image (3D model) generation technique similar to that used in a known 3D CAD system. The three-dimensional image may also be referred to as, for example, a 3D image, a three-dimensional model, or a 3D model. The three-dimensional image generating unit 11 may, for example, record the generated three-dimensional image in the storage unit of the device.

[0031] The material information is, for example, information about the materials that make up the target structure. The material information includes, for example, material identification information, material attribute information, etc. The material identification information is information that identifies the material, and includes identification information such as the name of the material and product number. The material attribute information includes, for example, information that indicates the characteristics of the material, such as material, size (length, depth, thickness, weight, etc.), physical properties (strength, fire resistance, thermal conductivity, density, etc.). The material is not particularly limited as long as it is a material that makes up the target structure, and may be, for example, a structural member, a connecting member that connects structural members, or other member. The connection information is, for example, information about the connections between materials included in the target structure. The connection information includes, for example, information about the connection locations of each member with other materials, information about the presence or absence of connections with other materials, information about the connection method between materials, etc. The connection method is not particularly limited, and examples thereof include, but are not limited to, welding, bolting, riveting, pressure welding, hybrid joining (a combination of multiple joining methods, such as welding and bolting, welding and rivets, etc.), pin joining, groove joining, reinforcement joining (a method of attaching a joining reinforcement member such as a gusset or end plate), joints (for example, mortise and tenon joints, mortise and tenon joints, and lap joints), joints (for example, tenon and tenon joints, dovetail joints, etc.), metal joints (for example, joints using plate metal, bolt metal, nail metal, etc.), screw joints (for example, joints using wood screws, screws, deck screws, etc.), adhesive joints, and other joining methods.

[0032] The CAD information may include, for example, other information. The other information is not particularly limited and may include, for example, location information, construction information, equipment information, cost information, schedule information, legal and regulatory information, maintenance information, and performance information. The location information is, for example, information indicating the spatial positional relationship of components, and may be absolute coordinates or relative coordinates. The construction information is, for example, information regarding the construction of the target structure, including information on the construction order and construction conditions. The equipment information is, for example, information regarding equipment to be installed in the target structure, including information on the specifications and placement of the equipment. The cost information is, for example, information regarding the costs involved in the manufacture (construction) of the target structure, including information on component costs and total costs. The schedule information includes information on the construction period and progress information related to the manufacture (construction) of the target structure. The legal and regulatory information is, for example, information regarding legal and regulatory regulations related to the manufacture (construction) of the target structure. As a specific example, if the target structure is a building, the legal and regulatory information may include, for example, information on the Building Standards Act and information on permits and licenses related to the construction of the target structure. The maintenance information is, for example, information about the maintenance of the target structure, such as information about regular maintenance plans, maintenance history, etc. The performance information is, for example, information about the performance of the target structure, such as information about the energy efficiency of the target structure, information about environmental impact assessment, etc.

[0033] The correction information acquisition unit 12 acquires correction information for the target structure (S2, correction information acquisition step). The correction information is, for example, information for correcting the target structure. The correction information includes identification information for the material to be corrected and material information for the material to be corrected after the correction. For example, the identification information for the material to be corrected can refer to the description of the material identification information above. The material information after the correction is information related to the correction of the material to be corrected, such as material attribute information for the material to be corrected, connection destinations after the correction (information identifying other materials to which the material to be corrected will be connected after the correction of the material to be corrected), and information on materials connected to the material to be corrected. The correction information acquisition unit 12 may acquire correction information entered by a user into the device 10, or may acquire correction information from other CAD software.

[0034] The influence range identifying unit 13 identifies the influence range in which the material to be corrected affects the target structure, based on the CAD information and the correction information (S3, influence range identifying step).

[0035] The processing of the influence extent identifying unit 13 will be described with reference to Fig. 4 and Fig. 5. Fig. 4 and Fig. 5 are flowcharts showing an example of the processing of the influence extent identifying unit 13.

[0036] The affected area identification unit 13 adds the correction target material to the recalculation list based on the correction information, for example (S31). The affected area identification unit 13 can add the correction target material to the recalculation list by recording the correction target material identified based on the identification information of the correction target material included in the correction information and the corrected material information in the storage unit of the device 10, for example.

[0037] The affected area identification unit 13 determines, for example, based on the CAD information and the modification information, whether there is a connected material to which the modification target material is connected (S32). The connected material to which the modification target material is connected is, for example, a material to which the modification target material itself is attached. More specifically, the connected material means, for example, another material to which one end and the other end of the modification target material are connected. The affected area identification unit 13 can determine whether the connected material exists by searching for the presence or absence of another material connected to one end and the other end of the modification target material in the target structure based on the CAD information and the modification information.

[0038] For example, if the connected material exists, the influence range identification unit 13 further determines whether the existing connected material is subject to recalculation (S33). For example, based on the CAD information and the modification information, the influence range identification unit 13 can determine that the connected material is subject to recalculation if modification of the modified material affects the shape of the connected material. For example, the influence range identification unit 13 can determine whether the relationship between the modified material and the connected material satisfies a predetermined condition, and if the predetermined condition is satisfied, determine whether modification of the modified material affects the shape of the connected material. The predetermined condition is not particularly limited, and appropriate conditions can be set depending on, for example, the type of target structure and the materials constituting the target structural material. For example, the predetermined condition can be when the connection method between the modified material and the connected material is a predetermined method, specifically, when modification of the modified material results in changes to component position coordinates. The connection method can be, for example, a joint, weld, gusset, splice, base, etc. The affected area identification unit 13 can, for example, identify the connection method between the material to be corrected and the connected material after correction based on the CAD information and the correction information, and determine whether or not the shape of the connected material is affected if the identified connection method satisfies specified conditions.

[0039] For example, if the connected material is to be recalculated (S33, Yes), the influence range identification unit 13 adds the connected material to be recalculated to a recalculation list (S34). Then, the influence range identification unit 13 can identify the influence range based on the recalculation list.

[0040] For example, if the connected material is to be recalculated, the influence range identification unit 13 may designate the connected material as a new material to be corrected (S35) and repeat the processes of S32 to S35 (recursive processing).Furthermore, if, for example, there is no connected material connected to the material to be corrected (S32, No), or if the connected material is not to be recalculated (S33, No), the influence range identification unit 13 may end the process and proceed to processing (S4) by the image correction unit 14, which will be described later.

[0041] For example, after S31, the impact extent identification unit 13 may execute the following S32A to S35A in addition to S32 to S35 or instead of S32 to S35. The impact extent identification unit 13 may execute, for example, either one of S32 to S35 or S32A to S35A, or both. Furthermore, the impact extent identification unit 13 may execute, for example, S32 to S35 and S32A to S35A sequentially or simultaneously. In the former case, there are no particular restrictions on the order in which S32 to S35 and S32A to S35A are executed, and they can be executed in any order.

[0042] The affected area identification unit 13 determines, for example, based on the CAD information and the modification information, whether there is a connecting material to which the modification target material is connected (S32A). A connecting material connected to the modification target material is, for example, a material that is attached to the modification target material. The connecting material means, for example, a material that has one end or the other end connected to a side of the modification target material. The affected area identification unit 13 can determine whether the connecting material exists by searching for other materials connected to the side of the modification target material in the target structure based on the CAD information and the modification information.

[0043] For example, if the connecting material exists, the influence range identification unit 13 further determines whether the existing connecting material is a target for recalculation (S33A). For example, based on the CAD information and the modification information, the influence range identification unit 13 can determine that the connecting material is a target for recalculation if the modification of the target material affects the shape of the connecting material. For example, the influence range identification unit 13 can determine whether the relationship between the target material and the connecting material satisfies a predetermined condition, and if the predetermined condition is satisfied, determine whether the modification of the target material affects the shape of the connecting material. The predetermined condition is not particularly limited, and appropriate conditions can be set depending on, for example, the type of target structure and the materials constituting the target structural material. For example, the predetermined condition can be when the connection method between the target material and the connecting material is a predetermined method, specifically, when the modification of the target material results in a change in component position coordinates. For example, the connection method can be a joint, weld, gusset, splice, base, etc. The affected area identification unit 13 can, for example, identify the connection method between the material to be corrected and the connecting material after correction based on the CAD information and the correction information, and determine whether or not the shape of the connecting material is affected if the identified connection method satisfies specified conditions.

[0044] For example, if the connecting material is to be recalculated (S33A, Yes), the influence range identification unit 13 adds the connecting material to be recalculated to a recalculation list (S34A). Then, the influence range identification unit 13 can identify the influence range based on the recalculation list.

[0045] For example, if the connecting material is to be recalculated, the affected area identification unit 13 may designate the connecting material as a new material to be corrected (S35A) and repeat the processes of S32A to S35A (recursive processing).Furthermore, if, for example, there is no connecting material connected to the material to be corrected (S32A, No), or if the connecting material is not to be recalculated (S33A, No), the affected area identification unit 13 may end the process and proceed to processing (S4) by the image correction unit 14, which will be described later.

[0046] The processing of the influence range identification unit 13 will be described using a specific example. In the following specific example, a steel-framed building shown in Fig. 6 will be used as an example of the target structure, but as mentioned above, the target structure of the present disclosure is not limited to steel-framed buildings. As shown in Fig. 6, the target structure 20 is a building in which main columns 21, girders 22, studs 23, and sub-girders 24 are connected by joints 25, splices 26, welds 27, gussets 28, etc.

[0047] In this case, an example of correcting the main pillar 21 shown in FIG. 6 will be described with reference to FIG. 7. First, the main pillar 21 shown in FIG. 6 is designated as the material to be corrected as the correction information. The influence range identification unit 13 first adds the main pillar 21, which is the material to be corrected, to a recalculation list. Next, the influence range identification unit 13 references the CAD information and the correction information and determines whether there are any connecting materials connected to the main pillar 21 and any connected materials to which the main pillar 21 is connected. The influence range identification unit 13 extracts the joint 25a and the girder 22a as connecting materials connected to the main pillar 21. Since correcting the main pillar 21 affects the shapes of the girder 22a and the joint 25a, the influence range identification unit 13 adds the girder 22a and the joint 25a to the recalculation list, and further designates the girder 22a and the joint 25a as new materials to be corrected, and repeats the process.

[0048] The influence range identification unit 13 determines whether there are any connecting materials connected to the girder 22a and any connected materials to which the girder 22a is connected. The influence range identification unit 13 extracts the splice 26, the main column 21b, and the joint 25b as the connected materials to which the girder 22a is connected. The influence range identification unit 13 also extracts the girder 22b, the secondary beam 24b, and the stud 23b as the connecting materials to be connected to the girder 22a. Since modifying girder 22a affects the shapes of joint 25b and main column 21b to which girder 22a is connected, as well as the shapes of girder 22b, sub-beam 24b, and stud 23b, influence range identification unit 13 adds joint 25b, main column 21b, girder 22b, sub-beam 24b, and stud 23b to the recalculation list, and further designates joint 25b, main column 21b, girder 22b, sub-beam 24b, and stud 23b as new materials to be modified, and repeats the process. Note that modifying girder 22a does not affect the shape of splice 26, so influence range identification unit 13 does not add splice 26 to the recalculation list.

[0049] The influence range identification unit 13 determines whether there are any connected materials to which the joint 25b, main column 21b, girder 22b, sub-beam 24b, or stud 23b is connected, or any connecting materials connected to the joint 25b, main column 21b, girder 22b, sub-beam 24b, or stud 23b. The influence range identification unit 13 extracts the sub-beam 24c as the connecting material of the girder 22b, and extracts the girder 22c as the connecting material between the main column 21b and the joint 25b. Since modifying the girder 22b affects the shape of the sub-beam 24c, the influence range identification unit 13 adds the sub-beam 24c to the recalculation list, designates the sub-beam 24c as a new material to be modified, and repeats the process. Since modifying the main pillar 21b and joint 25b will affect the shape of the girder 22c, the affected area identification unit 13 adds the girder 22c to the recalculation list, designates the girder 22c as a new material to be modified, and repeats the process.

[0050] The influence range identification unit 13 determines whether there are any connecting materials connected to the sub-beam 24c or the girder 22c and any connected materials to which the sub-beam 24c or the girder 22c is connected. The influence range identification unit 13 extracts the girder 22d as the connected material to which the sub-beam 24c is connected. The influence range identification unit 13 also extracts the splice 26d as the connected material to which the girder 22c is connected. On the other hand, since the modification of the sub-beam 24c does not affect the shape of the girder 22d and the modification of the girder 22c does not affect the shape of the splice 26d, the processing by the influence range identification unit 13 is terminated and the processing proceeds to S4, which will be described later.

[0051] The processing of the influence range identification unit 13 will be described using another specific example. In this example, a case where the girder 22a shown in FIG. 8 is corrected will be described as an example. First, the girder 22a is designated as the material to be corrected in the correction information. The influence range identification unit 13 first adds the girder 22a, which is the material to be corrected, to the recalculation list. Next, the influence range identification unit 13 references the CAD information and the correction information and determines whether there are any connecting members connected to the girder 22a and any connected members to which the girder 22a is connected. The influence range identification unit 13 extracts the joints 25a, 25b and the main columns 21, 21b as connected members to which the girder 22a is connected. Furthermore, the influence range identification unit 13 extracts the sub-beam 24b and the stud 23b as connecting members to be connected to the girder 22a. When the main beam 22a is modified, the shapes of the joints 25a, 25b, main columns 21, 21b, secondary beam 24b, and stud 23b are affected, so the affected area identification unit 13 adds the joints 25a, 25b, main columns 21, 21b, secondary beam 24b, and stud 23b to the recalculation list, and further designates the joints 25a, 25b, main columns 21, 21b, secondary beam 24b, and stud 23b as new materials to be modified, and repeats the process.

[0052] The influence range identification unit 13 determines whether there are any connected materials to which the joints 25a, 25b, the main columns 21, 21b, the joists 24b, or the studs 23b are connected, or any connecting materials connected to the joints 25a, 25b, the main columns 21, 21b, the joists 24b, or the studs 23b. The influence range identification unit 13 extracts the girder 22a as the connecting material connected to the main column 21 and the joint 25a, extracts the girder 22c as the connecting material connected to the main column 21b and the joint 25b, and extracts the girder 22b as the connected material of the joists 24b. Because modifying the main column 21 and the joint 25a affects the shape of the girder 22a, the influence range identification unit 13 adds the girder 22a to the recalculation list, designates the girder 22a as the new material to be modified, and repeats the process. When the main column 21b and the joint 25b are modified, the shape of the main girder 22c is affected, so the influence range identification unit 13 adds the main girder 22c to the recalculation list, designates the main girder 22c as a new material to be modified, and repeats the process. When the secondary beam 24b is modified, the shape of the main girder 22b is not affected, so the influence range identification unit 13 does not add the main girder 22b to the recalculation list.

[0053] The influence range identification unit 13 determines whether there is a connected material to which the girder 22a or the girder 22c is connected, or a connecting material connected to the girder 22a or the girder 22c. The influence range identification unit 13 extracts splice 26b as the connecting material of the girder 22a, and extracts splice 26d as the connecting material of the girder 22c. Even if the girder 22a and the girder 22c are modified, the shapes of the splices 26b and 26d are not affected, so the influence range identification unit 13 does not add the splices 26b and 26d to the recalculation list. The processing by the influence range identification unit 13 ends, and the process proceeds to the processing of S4, which will be described later.

[0054] The processing of the influence range identification unit 13 will be described using another specific example. In this example, a case where the girder 22b shown in FIG. 9 is corrected will be described as an example. First, the girder 22b is designated as a material to be corrected in the correction information. The influence range identification unit 13 adds the girder 22b, which is the material to be corrected, to a recalculation list. Next, the influence range identification unit 13 references the CAD information and the correction information and determines whether there are any connecting members connected to the girder 22b and any connected members to which the girder 22b is connected. The influence range identification unit 13 extracts the girder 22a and the girder 22c as connected members to which the girder 22b is connected. The influence range identification unit 13 also extracts the sub-girder 24c as a connecting member to be connected to the girder 22b. Since correcting the girder 22b affects the shape of the sub-girder 24c, the influence range identification unit 13 adds the sub-girder 24c to the recalculation list, and further designates the sub-girder 24c as a new material to be corrected, and repeats the processing. Even if the girder 22b is corrected, the shapes of the girder 22a and the girder 22c are not affected, and therefore the influence range specifying unit 13 does not add the girder 22a and the girder 22c to the recalculation list.

[0055] The influence range identification unit 13 determines whether there are any connecting materials connected to the sub-beam 24c and any connected materials to which the sub-beam 24c is connected. The influence range identification unit 13 extracts the main beam 22d and the main beam 22b as the connected materials to which the sub-beam 24c is connected. On the other hand, since the modification of the sub-beam 24c does not affect the shapes of the main beam 22d and the main beam 22b, the processing by the influence range identification unit 13 is terminated and the process proceeds to S4, which will be described later.

[0056] The processing of the influence range identification unit 13 will be described using another specific example. In this example, a case where a sub-beam 24b (sub-beam 24b shown in gray in FIG. 10) shown in FIG. 10 is corrected will be described. First, the sub-beam 24b is designated as the material to be corrected in the correction information. The influence range identification unit 13 adds the sub-beam 24b, which is the material to be corrected, to the recalculation list. Next, the influence range identification unit 13 refers to the CAD information and the correction information and determines whether there are any connecting materials connected to the sub-beam 24b and any connected materials to which the sub-beam 24b is connected. The influence range identification unit 13 extracts the girders 22a and 22b as the connected materials to which the sub-beam 24b is connected. Even if the sub-beam 24b is corrected, the shape of the girders 22a and 22b is not affected, so the influence range identification unit 13 does not add the girders 22a and 22b to the recalculation list. The processing by the influence range identification unit 13 ends, and the process proceeds to S4, which will be described later.

[0057] Then, the image correction unit 14 corrects the three-dimensional image based on the CAD information, the correction information, and the range of influence (S4, image correction step). The image correction unit 14, for example, refers to the recalculation list and regenerates the three-dimensional image for the materials that affect the target structure based on at least one of the CAD information and the correction information. The method of generating the three-dimensional image in S4 may be the same as or different from S1, for example.

[0058] The three-dimensional image generation support method of the present disclosure is, for example, a method implemented by replacing each "procedure" in the three-dimensional image generation support program of the present disclosure with a "step." The three-dimensional image generation support method of the present disclosure can be implemented, for example, using the three-dimensional image generation support device 10 of the present disclosure shown in FIG. 1 or FIG. 2. Note that the three-dimensional image generation support method of the present disclosure is not limited to methods that use the three-dimensional image generation support device 10. For example, the descriptions of the three-dimensional image generation support program and the three-dimensional image generation support device of the present disclosure can be used for the three-dimensional image generation support method of the present disclosure.

[0059] The three-dimensional image generation support program of the present disclosure identifies the range of influence that the material to be modified has on the target structure using the influence range identification unit 13, and modifies only the three-dimensional image related to the material in the recalculation list using the image modification unit 14, thereby optimizing the modification location of the three-dimensional image. Therefore, the three-dimensional image generation support program of the present disclosure can reduce the processing load when modifying a three-dimensional model (three-dimensional image) in CAD software, for example. Therefore, the three-dimensional image generation support program of the present disclosure can also realize, for example, real-time reflection of modifications to the 3D model accompanying modifications to a two-dimensional drawing.
