Description

  The present invention relates to a three-dimensional design support apparatus that supports creation of a surface design of a three-dimensional model, and in particular, a three-dimensional model that allows a user-specific model to be easily created simply by attaching image data to a model development view. The present invention relates to a design support apparatus and a program.

  In recent years, communication that has been performed one-on-one through the Internet has also been performed in a shared virtual space on a network, and has been performed simultaneously with a plurality of users participating in the network. At this time, an avatar is used as a virtual character representing each user.

  Avatars used in such a communication field are mainly humanoid characters. Since an avatar is expressed as a user-specific character that communicates with it, parts such as eyes, nose, and mouth prepared for each part of the face used for the human-type character are operated by the user. Thus, an avatar more similar to the user himself is created by being combined as a human face (see, for example, Patent Document 1). Thereby, the avatar used by other users in the shared space has been distinguished. On the other hand, if it is a humanoid character as a physical feature excluding the face, in addition to differences in physique among women, men, adults, and children, avatars should wear clothes (for example, In Japanese Patent Application Laid-Open No. 2004-228561, individuality for each user has been expressed.

And

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a block diagram showing a configuration of a three-dimensional design support apparatus applied in this embodiment. As shown in the figure, the three-dimensional design support apparatus includes a CPU (Central Processing Unit) 101, a main memory 102, an input device 103, a display device 104, a hard disk drive (HDD) 105, and a CD-ROM / DVD drive 106. And. Further, the display device 104 includes a display screen 114, and a recording medium (DVD-ROM or CD-ROM in this embodiment) 121 can be mounted on the DVD / CD-ROM drive 106.

  The CPU 101 executes a program stored on the HDD 105 or the recording medium 121 to control the apparatus main body. The main memory 102 is a work area of the CPU 101, and information on the coordinate position of the pasted image, its size, and the like is temporarily stored in the main memory 102. The HDD 105 is used as a storage area for storing programs and data.

  The DVD / CD-ROM drive 106 reads programs and data from the recording medium 121. The input device 103 is a mouse used as a pointing device, a keyboard having direction keys, or the like. The keyboard is used for text input, an operation for causing the object to perform a predetermined operation, or a change in the relative positional relationship between the object and the virtual camera, and further, a mouse drag operation and a drop operation are performed. The object and the pasted image on the display screen 114 can be moved. The input data from the input unit 103 is output to the main memory 102, and the CPU 101 interprets it and executes arithmetic processing.

  The program and data executed by the 3D design support apparatus are first stored in the recording medium 121, for example. The data stored in the recording medium 121 includes an avatar that exists in a virtual three-dimensional space, graphic data for configuring a clothing model, a cutting diagram corresponding to the clothing model, and the like. The program and data stored in the storage medium 121 are read by the DVD / CD-ROM drive 106 at the time of execution and loaded into the main memory 102. The CPU 101 processes the program and data loaded in the main memory 102 and outputs a drawing command to the display device 104. Intermediate data while the CPU 101 is performing processing is stored in the main memory 102.

  The CPU 101 expands the image data and displays an image on the display screen 114 of the display device 104. One frame time of an image output from the CPU 101 is, for example, 1/60 second. The CPU 101 generates image data of a two-dimensional image obtained by perspective-transforming an object (avatar, clothes model, etc.) existing in a virtual three-dimensional space with a virtual camera, and displays the image data together with other image data used for a user operation. 114 is displayed. In such image processing, a control device for image processing (including GPU, ROM, etc.) may be used.

  The three-dimensional design support apparatus according to this embodiment is a clothing that a user wears on a character that can be operated as an avatar in a virtual three-dimensional space (which will be described below as a humanoid character expressed in three dimensions). Execute support to create (represented in three dimensions like a character) mainly by dragging and dropping a mouse (hereinafter simply referred to as “drag and drop”) based on a predetermined clothing model .

  As shown in FIG. 2, a clothing model expressed in three dimensions is expanded in two dimensions corresponding to the clothing model, and a cutting diagram (hereinafter simply referred to as “type”) of the clothing model is displayed for each clothing model. The user drags and drops a desired image (for example, an image compressed in the GIF format) onto the type. As a result, the image is pasted on the mold, and the image is mapped to the clothing model as a texture. Each type is divided for each part (sleeve, body part, etc.) of the clothes model, and is arranged on a plane within one frame.

  FIG. 3 shows the correspondence between the polygon of the clothing model 302 and the mold 307. The figure shows the clothing model 302 and the front side of the body of the mold 307. First, the clothing model 302 is composed of a plurality of triangular or quadrangular polygons, and a plurality of them are connected to each other and represented as a three-dimensional clothing model 302. Each polygon with a number on the surface of the clothing model 302 composed of a plurality of polygons is attached with a number on the surface of the front side of the body in the mold 307 expressed in two dimensions. The portions are associated with each other. Accordingly, an image similar to the image pasted on the mold 307 represented in two dimensions is represented on the surface of the clothing model 302 represented in three dimensions.

  The mapping of the image pasted on this mold onto the clothing model surface is performed by bump mapping. Here, the bump mapping is a mapping technique that expresses pseudo unevenness on the surface of the object by shifting the normal line for each pixel of the texture mapped on the polygon of the object. In other words, the reflected light from the light source in the virtual three-dimensional space is shifted by shifting the normal line for each pixel. Therefore, in the image obtained by changing the perspective of the image, the shadow of the object surface changes. Apparent irregularities are expressed. In addition, irregularities such as clothes wrinkles caused by the movement of the avatar are expressed by this bump mapping together with the change of the polygon of the clothes model according to the movement.

  Next, FIG. 4 shows an example of the transition of the display screen 114 and explains the outline of the processing of the three-dimensional design support apparatus according to the embodiment of the present invention. In the present embodiment, an avatar 301 and a clothing model selection screen 303 as shown in FIG. 4A are displayed on the display screen 114, and the user creates his / her own avatar 301 in accordance with instructions on the message display screen 304. Clothes are selected from the clothes model option 305 using a mouse click operation (click operation for placing the mouse cursor 310 on the desired clothes model option 305). The avatar 301 is displayed with the clothes model 302 corresponding to the selected clothes model option 305 being worn, and the selected clothes model option 305 is A cursor 306 indicated by a hatched frame is displayed in the part.

  In the display screen 114 of FIG. 4A, when a user-desired clothing model 302 to be created is selected from the clothing model selection 305 according to an instruction on the message display screen 304, and the user clicks the edit button 311. Subsequently, on the display screen 114, as shown in FIG. 4B, a clothing self-made screen 308 is displayed instead of the clothing model selection screen 303, and a mold 307 corresponding to the selected clothing model 302 is displayed there. Is displayed. On the message screen 304, an instruction to paste the pasted image on the mold 307 is displayed, and the user reads the image stored in the HDD 105 or the like and pastes it on the self-made screen 308.

  Subsequently, as illustrated in FIG. 4C, the pasted image 309 read by the user is displayed so as to be superimposed on the mold 307 on the clothing self-made screen 308. In the portion of the mold 307 that overlaps the pasted image 309, the pasted image 309 is displayed as a texture in the corresponding portion on the clothing model 302. That is, in the case of the display screen 114 shown in FIG. 4C, all of the molds 307b and 307c as the shoulder sleeve portions of the clothing model 302 overlap with the pasted image 309, and the clothing model 302 as the trunk portion. Since the upper half of 307a (clothing back portion, the lower direction of display screen 114 is the neck direction of clothing model 302) and 307d (clothing front portion) overlap, The pattern and color similar to the pasted image 309 are pasted as texture only on the upper half of the body portion.

  At this time, the position and direction of the virtual camera with respect to the avatar 301 can be changed by operating the direction key of the keyboard. This is, for example, changing the camera position and direction while maintaining a certain distance around the avatar 301. As a result, as shown in FIG. 4C, not only the avatar 301 facing the front but also the avatar 301 facing the direction deviating from the front as shown in FIG. It will be displayed on the display screen 114.

  Further, by operating a predetermined key on the keyboard, the avatar 301 can perform a predetermined operation. The predetermined action is the same action as the action that the avatar 301 performs in the shared virtual space, such as walking, running, jumping, and squatting. Along with such an operation, the clothes model is deformed, and a plurality of polygons in the clothes model are deformed accordingly. By performing bump mapping, movements such as wrinkles and shimmering are confirmed in the clothes worn by the avatar 301. In the process of self-made clothing, the avatar 301 can be made to perform this kind of operation, and the self-made clothing model 302 is also wrinkled and shuffled.

  During the execution of the process in the 3D design support apparatus according to the embodiment of the present invention, the mouse cursor 310 is always displayed on the display screen 114, and by dragging and dropping the mouse on the pasted image 309, The position of the pasted image 309 with respect to the mold 307 can be changed. For example, the mouse cursor 310 is placed on the pasted image 309 displayed in FIG. 4C, and the pasted image 309 is moved downward by dragging and dropping from there. FIG. 5B shows the display screen 114 after the movement. Thus, by changing the position of the pasted image 309, the range of the mold 307 overlapping the pasted image 309 is also different from that before the movement. In FIG. 5B, due to the change in the position of the pasting image 309, most of the mold 307d overlaps with the pasting image 309, and the texture of the clothing model 302 reflected thereby is largely the pasting image. The texture changes to the same pattern and color as 309.

  Once the pasting position of the pasting image 309 is determined, the user can finish creating the clothes at any time by clicking the end button 312 and, at the same time, decide whether or not to save the self-made clothes as data. become. When saving, the clothes model selection screen 303 is displayed side by side as clothes model choices 305 as shown in FIG. 5 (c). The data of the clothes model 302 is discarded, and the display screen 114 returns to the one shown in FIG.

  The processing in the 3D design support apparatus according to this embodiment will be described below with reference to the flowchart shown in FIG.

  First, when a clothing model 302 is selected by the user and an operation for starting own creation is performed (step S101), the CPU 101 reads a mold 307 corresponding to the selected clothing model 302 and displays it on the display screen 114 ( Step S102).

  Next, the CPU 101 determines whether or not the user has performed an operation for reading the pasted image 309 (step S103). When the operation for reading the pasted image 309 is performed, the CPU 101 pastes the pasted image 309 on the clothes self-made screen 308 (step S104). Subsequently, the CPU 101 determines whether or not the pasted image 309 has been pasted or moved (step S105). If the pasted image 309 has been pasted or moved, whether or not the pasted image 309 subsequently overlaps the mold 307. Is determined (step S106). If the CPU 101 determines that they overlap in step S106, the CPU 101 pastes a range corresponding to the overlapping portion as a texture on the clothing model 302 (step S107). Further, the CPU 101 determines whether or not there is a direction key input from the keyboard (step S108), and if there is an input of the direction key, the avatar 301 is turned according to the input direction (step S109). Subsequently, the CPU 101 determines whether or not there is an input for causing the user's avatar 301 to perform a predetermined operation (step S110). If there is an input by the user for causing the avatar 301 to perform a predetermined operation, the CPU 101 causes the avatar 301 to execute a predetermined operation corresponding to the input (step S111).

  Subsequently, the CPU 101 changes the display of the display screen 114 based on the above-described operation on the avatar 301 and the self-made clothing screen 308 (by the image obtained by performing the perspective transformation process on the avatar 301). (Step S112).

  On the other hand, the processing of the CPU 101 proceeds to step S105 when it is not determined in step S103 that the pasted image 309 has been read. Further, the processing of the CPU 101 proceeds to step S108 when it is not determined in step S105 that the image has been pasted or moved, or when it is not determined in step S106 that the mold and the image overlap. Further, the process of the CPU 101 proceeds to step S110 when it is not determined in step S108 that an input has been detected for the direction key. Further, the processing of the CPU 101 proceeds to step S112 when an input for causing the avatar 301 to perform a predetermined operation is not detected in step S110.

  When the display screen 114 is changed in step S112, the CPU 101 determines whether or not the creation of the user's clothes has been completed (step S113). The user selects whether to save clothes (step S114). If the creation of the user's clothes has not been completed, the process of the CPU 101 returns to step S103 again. A series of processing of the CPU 101 performed from step S103 to step S113 is executed within one frame period.

  When it is selected in step S114 that the user's own clothes are to be stored, the CPU 101 stores the user's own clothes in the HDD 105 or the like (step S115). In step S114, when the selection to save the self-made clothes is not made, or when the self-made clothes are saved in step S115, the CPU 101 causes the user to select whether or not to create the clothes (step S116). In the case of further creating clothes, the CPU 101 moves the process to step S101, and if no more clothes are created, the process in the three-dimensional design support apparatus is terminated.

  As described above, in the three-dimensional design support apparatus, the clothes model 302 expressed in three dimensions by a plurality of polygons and the corresponding mold 307 in which the surface shape of the clothes model 302 is expanded in two dimensions are described. And stored in the main memory 102 together with information indicating the corresponding relationship. Further, the pasted image 309 stored in the HDD 105 or the like is read by the user, displayed on the clothes creation screen 308 together with the mold 307, and the position of the pasted image 309 with respect to the mold 307 is changed by the user's drag and drop operation. be able to.

  In this way, the pasted image 309 arbitrarily moved with respect to the mold 307 according to the user's operation is mapped to the clothing model 302 according to the information indicating the correspondence, and thus the clothing model to which the pasted image 309 is pasted. 302 is displayed on the display screen 114. The user edits the surface design of the clothing model 302 to which the arbitrary image is attached by simply moving the position of the arbitrary pasted image 309 with respect to the mold 307 by drag and drop operation and determining it. Will be able to. Further, since the pasted image 309 can be arbitrarily selected, the width of the design is not reduced.

  The avatar 301 wearing the clothes model 302 to which the pasted image 309 is mapped is perspective-transformed by a virtual camera, and the perspective-transformed image is displayed on the display device 114, but the user operates a direction key on the keyboard. Thus, the position of the virtual camera and the direction of the visual axis can be changed, and the relative positional relationship with the avatar 301 can be changed.

  By changing the relative positional relationship between the virtual camera and the avatar 301, the display device 114 can confirm how the surface design of the clothes model 302 with the pasted image 309 is seen from various angles. A well-balanced design can be easily created from the direction.

  In addition, in this manner, with the clothes model 302 being worn by the avatar 301, the design can be performed while confirming the clothes model 302 to which the pasted image 309 is pasted on the display device 114. Since the user can check not only the quality of the design but also the quality when the avatar 301 is worn, it is possible to prevent the clothes that have undergone the design editing from being unsuitable for the avatar 301.

  In addition, when the user operates a predetermined key on the keyboard, the avatar 301 performs, for example, walking, running, jumping, squatting, and the like in a virtual space while creating the design of the clothes model 302. Can be made. When the clothes model 302 is expressed by the movement of the avatar 301, the clothes design 302 can be confirmed in a state where the clothes model 302 is deformed by the expression. If you do this, you can prevent the design from being spoiled.

  The present invention is not limited to the above-described embodiment, and various modifications and applications are possible. Hereinafter, modifications of the above-described embodiment applicable to the present invention will be described.

  In the above embodiment, the body shape of the avatar 301 and the size of the clothes model 302 associated therewith are not particularly described, but the shape of the mold 307 corresponding to the shape change of the clothes model 302 accompanying the body shape of the avatar 301 is changed. It may be changed. Also, the clothing model 302 corresponding to the body shape of the avatar 301 is not determined to be a single one, and the user can select a clothing model 302 having a large size or a clothing model 302 having a small size for the body shape of the avatar 301. You may do it. Moreover, the length of the length accompanying such selection may be changed.

  In the above embodiment, the arrangement of each part of the mold 307 corresponding to the clothes model 302 is not changed, but the user can freely change the arrangement on the clothes self-made screen 308. It is good. Thereby, for example, as shown in FIG. 7, the arrangement of each part of the mold 307 can be changed. That is, the initial arrangement of the mold 307 as a default is as shown in FIG. 2, and the arrangement can be freely changed by the user's operation. In addition, the mold 307 that has been rearranged as described above may be stored as data in the same manner as the data for the clothes that were created in the above embodiment.

  As an operation performed by the user related to this arrangement change, for example, an arrangement change by a drop-and-drag operation performed on each part of the mold 307 or a part selection cursor 501 as shown in FIG. It is also possible to change the arrangement by selecting a part of the desired mold 307 and operating a direction key on the keyboard. Further, along with this arrangement change, the user may be able to perform an operation for rotating the part of the mold 307.

  In addition, in the above embodiment, the position of the pasted image 309 is changed with respect to the mold 307 when the location of each part of the mold 307 can be changed. The arrangement of each part of the mold 307 can be changed for each part. That is, the mold 307 is moved on the pasted image 309 by drag and drop or the like. As a result, for example, it is possible to perform design correction that does not cause a case where the joint of the developed view becomes unnatural. In addition, a favorite design for each part can be adopted for the image design included in the pasted image 309.

  The pasted image 309 that can be pasted on the mold 307 at the same time is not particularly shown in the above embodiment, but the user may be able to paste a plurality of pasted images 309. That is, since an arbitrary image can be attached to each part, a self-made clothes model 302 having a different pattern and color desired by the user can be easily created for each part of the clothes model 302. In addition, in pasting such a plurality of pasted images 309, a plurality of pasted images 309 can be pasted in layers by transmitting a part of the pasted images, transmitting a part thereof, or changing the transmittance thereof. It may be possible. In editing such as these, it is possible to edit the pasted image 309 itself, such as enlargement, reduction, deformation, or color change, with respect to the pasted image 309 read on the self-made screen 308. The editing state may be displayed on the clothing model 302 over a period of time.

  In the above embodiment, the user needs to perform a drag-and-drop operation to move the pasted image 309 on the self-made screen 308. As an operation for this movement, the direction provided on the keyboard A key may be used. In addition, when there are a plurality of pasted images 309 to be moved, the user may visually recognize the moving object through the display screen 114 by displaying a cursor around the object. At this time, in the selection of the movement target, the selection may be made by clicking the target with the mouse or by sequentially sending the target with the TAB (item feed) key provided on the keyboard.

  In the above embodiment, when the avatar 301 is perspective-transformed and displayed on the display screen 114, the location of the light source in the virtual three-dimensional space where the avatar 301 exists is not particularly described. The position of the light source is fixed or changed so that the user can visually recognize the shadow of the clothes worn by the avatar 301 represented by the light source and the shadow of the avatar 301 including the clothes on the display screen 114. It may be. This light source is, for example, the sun, lighting, or the like used to more realistically represent the space in the shared virtual space. Thus, when editing the design of clothes, the reproduction of the shadow in the shared virtual space is easy for the user to imagine how the avatar 301 wearing the user's own clothes looks in the shared virtual space. This saves the effort of trial in the shared virtual space.

  In the above embodiment, the object as the target for editing the design by pasting the image is the clothes of the character that is the avatar 301. For example, the object of an automobile that makes this target exist in a three-dimensional virtual space. It is good also as an exterior (film stuck on the motor vehicle called a wrapping car) etc.

  Regardless of whether it is for home use or business use, the edited design is the target of editing the design by the output device that can output the edit of the design performed on the object to the target. It is good also as what can output with respect to what is equivalent. At this time, the output device and the equivalent of the output target are, for example, a household printer as the output device and a small garment (for example, a figure or the like) to be put on (printed) Garment), or a three-dimensional printing apparatus for business use as an output device, and a model exterior (for example, exterior of a model car) to be output (printed) thereby. As a result, design edits for clothes and the like performed by the user can be reproduced not only in the shared virtual space but also in the real space, which is interesting for the user.

  In the above embodiment, the pasted image 309 is a still image stored in advance in the HDD 105 or the like. However, a desired frame can be selected by a user's operation from a moving image captured using a digital camera or the like. May be captured and read into the three-dimensional design apparatus and used as the pasted image 309. In addition, by allowing the pasted image 309 to be taken in from the outside of the three-dimensional design apparatus as described above, the degree of freedom in editing the clothes design of the user is further increased, and more personalized clothes can be made by oneself. .

  When a camera that captures a moving image is connected to the 3D design support apparatus, a still image of a desired frame may be captured from a moving image captured in real time by the camera. Alternatively, a still camera may be connected to the three-dimensional design support apparatus, and an image photographed thereby may be stored in the HDD 105 or the like and used as the pasted image 309. Thereby, even when abundant images are not prepared in advance, the user can take a desired image and perform a three-dimensional design such as avatar clothes.

  In the above embodiment, the program and data of the three-dimensional design support apparatus are stored in the recording medium 121 and distributed. On the other hand, when the 3D design support apparatus is connected to a server apparatus existing on an external network and has a communication interface for communication, these programs and data are stored in a fixed disk apparatus included in the server apparatus. In addition, it may be distributed to the three-dimensional design support apparatus via a network. In the three-dimensional design support apparatus, programs and data received by the communication interface from the server apparatus can be stored in the HDD 105 and loaded into the main memory 102 at the time of execution.
