[Game description]
FIG. 3 is a diagram for explaining an outline of the game in the present embodiment.
The game of this embodiment is a virtual sculpture game in which a sculpture material is imitated on a sculpture material in a virtual reality space (VR space) and the result is evaluated.

  Specifically, in a virtual three-dimensional space configured with the same scale as the real space (see FIG. 1), a sculpture material 10, a target presentation panel 21 showing an image of the target 20, and a time limit display are displayed as VR objects. 22, a virtual engraving tool 30, a virtual gripping hand 32, a virtual hitting hand 34, a virtual camera 36R for the right eye, and a virtual camera 36L for the left eye.

  The engraving material 10 is an object to be engraved. As shown in FIG. 4, the engraving material 10 is a VR object group in which a large number of unit materials 12 which are VR objects of a small size are densely arranged according to a predetermined arrangement rule, and appear as if they are an integral lump. is there.

  In the example of FIG. 4, the external shape of the engraving material 10 is a cube, but can be appropriately set according to the shape of the target 20. For example, a rectangular parallelepiped, a polyhedron, a sphere, an ellipsoid, a cone, a winding tube, a box, a string, or a shape in which these are connected may be used. The size of one engraving material 10 is set so as to increase as the game difficulty level increases.

  Further, in the dense arrangement of the unit materials 12, the unit materials 12 may be arranged so that a gap is generated between the adjacent unit materials 12.

  The unit material 12 used for the engraving material 10 is a transparent or translucent cubic object in this embodiment, but the shape of the unit material 12 is not limited to a cube. For example, not only a sphere, various polyhedrons, ellipsoids, and cones, but also a three-dimensional heart shape or star shape may be used.

  As shown in FIG. 5, the arrangement size of the unit material 12 used for one engraving material 10 is basically set so as to decrease as the game difficulty level increases. The volume of one engraving material 10 is basically set to increase as the game difficulty level increases. That is, the player sculpts a larger engraving material 10 composed of a larger number of unit materials 12 as the game difficulty level increases.

  The type of unit material 12 used for one engraving material 10 (defined in this embodiment by a combination of shape and size) is not limited to the same. Different sizes may be mixed even in the same shape, or unit materials 12 having different shapes and different sizes may be mixed.

  Returning to FIG. 3, the target 20 is a three-dimensional model that the player should aim at by engraving the engraving material 10 and is colored. In this embodiment, since the game is based on the theme of sculpture, it is called “theme”. The content of the target 20 can be set as appropriate. If the game difficulty level is low, the shape is relatively simple, the number of colors used is small, and the coloring is relatively simple. For example, apples, bananas, and postboxes are good examples. On the other hand, if the game difficulty level is high, the shape is relatively complicated, and the number of colors used is large and it is difficult to imitate the coloring. A good example is a character or animal such as a manga or animation that has protrusions as shown in the figure and in which the relative position and size balance of each part are important.

  The target 20 is displayed in a predetermined position relative to the engraving material 10 when viewed from the player (for example, a position that is always a predetermined distance away from the engraving material 10 to the right or above). Then, the target 20 is rotated and displayed at a constant cycle or is automatically controlled according to the positional relationship between the engraving material 10 and the player so that the overall uneven position can be easily understood. For example, when the player is looking at the front side of the engraving material 10 (when the right-eye virtual camera 36R and the left-eye virtual camera 36L are facing the front of the engraving material 10), the front of the target 20 Is displayed, and when the player turns rightward toward the front of the engraving material, the rotation is controlled so that the right side is displayed toward the front of the target 20.

  The time limit display 22 indicates the remaining time that can be used for engraving and coloring.

  The virtual engraving tool 30 is placed and controlled in synchronization with the position and posture of the controller 8 in the real space based on the result of the controller tracking. The design of the virtual engraving tool 30 may or may not be changed as appropriate according to the switching of the tool type by the dial switch 84 described later.

The virtual grasping hand 32 is one of the left and right hands holding the virtual engraving tool 30 in the virtual three-dimensional space.
The virtual hitter 34 is the other left and right virtual hands that operate in the manner of hitting the rear end of the virtual engraving tool 30. The virtual hitter 34 may have a shape such as a noh or a wooden mallet.

  The right-eye virtual camera 36R and the left-eye virtual camera 36L correspond to the virtual right eye and left eye of the player 2 in the virtual three-dimensional space. The shooting angle of view of the right-eye virtual camera 36R and the left-eye virtual camera 36L is set to be equivalent to a human naked eye. Then, the position and posture are automatically controlled so as to maintain a predetermined relative position with respect to the head position of the player 2 in the virtual space determined in synchronization with the result of the head tracking and always face the front of the head. The

  A right-eye image based on a virtual three-dimensional space image captured by the right-eye virtual camera 36R and a left-eye image based on a virtual three-dimensional space image captured by the left-eye virtual camera 36L, respectively. It is displayed on the HMD 6 and provides the player 2 with a field of view as if he was in the virtual three-dimensional space (VR space) and looking with the naked eye.

  In the present embodiment, a guide for producing a sculpture similar to the target 20 can be displayed on the engraving material 10. For example, as shown in FIG. 6, a guide 14 is arranged as a guide for production, which is compared with the target object 20 so as to be embedded in the engraving material 10. That is, the guide 14 can be seen in the engraving material 10 through the transparent or translucent unit material 12 to the player 2.

The display form of the guide 14 can be set as appropriate, but the following display form is conceivable.
1) A set of unit materials 12 that are set to have the same shape and size as the unit materials 12 constituting the engraving material 10 but have a different display form (for example, different transparency, slightly colored, etc.).
2) A group of minute objects that is a collection of objects smaller than the unit material 12.
3) A surface or line along the contour or boundary of the unit material 12.
4) Surfaces and lines arranged irrespective of the outline and boundary of the unit material 12.
The display form of the guide 14 can be realized by one or a combination of these.

More specifically,
A) Pixel-type guide 14a in which the target 20 is composed of the unit material 12;
B) Independent curved surface type guide 14b constituted by an independent curved surface in which the outline of the target 20 is simplified,
C) A fragment-type guide 14c which is formed by simplifying the outline of the target 20 and further comprising independent surfaces or lines of the fragment.
2) a box-type guide 14d constituted by a contour of a primitive shape including the target 20;
E) Point-type guide 14e composed only of points reminiscent of the width and height of the important points of the target 20,
F) Non-display guide 14f without display,
Etc. can be set. Of course, these combinations are also possible.

  A plurality of such guides 14 are prepared in advance for one target 20 and are selected according to the guide level determined according to the setting of the game difficulty level and the skill level of the player. Is displayed. The higher the guide level, the closer to the target 20 and the finer accuracy (high definition) guide.

  In the present embodiment, the process of arranging the engraving material 10 is presented to the player 2. Specifically, after the guide 14 is arranged, the unit material 12 is gradually arranged from the central portion of the engraving material 10 toward the outer edge portion to form the engraving material 10, and before the start of play, Make advance preparations for preparation.

FIG. 7 is a diagram for explaining a virtual engraving method in the present embodiment.
In the present embodiment, a three-axis acceleration sensor 855 (see FIG. 2) of the controller 8 detects an acceleration pulse Gx as if the rear end of the controller 8 was hit in a single direction toward the tip, and the virtual engraving tool When the tip position of 30 is close to any unit material 12 of the engraving material 10 within the reference value, an “execution instruction operation to delete the unit material” or “erase operation”, that is, “engraving operation” is input. Is considered to have been Then, by erasing the unit material 12, the engraving material 10 is virtually cut.

  As described above, since the unit material 12 of the present embodiment is set as a transparent body or a semi-transparent body, the player 2 can see the interior of the engraving material 10 slightly. If the tip of the virtual engraving tool 30 is inserted into the engraving material 10, the location of the tip can be seen. If the engraving operation is performed with the tip of the virtual engraving tool 30 inserted into the engraving material 10, the unit material 12 inside the engraving material 10 can be erased. That is, according to the present embodiment, it is possible to cut from the inside of the engraving material 10 and create a product with the shape of the internal space.

  The number of unit materials 12 to be erased in response to one engraving operation, in other words, the number of unit materials 12 to be “erased units” is not limited to one. In this embodiment, the erase unit is controlled to change during play. This will intentionally interweave the irregularity that the unexpected amount will be cut at an unexpected timing, reproduce the realistic play sensation of sculpting the heterogeneous engraving material 10, and difficult as a game Can be appropriately produced.

Specifically, as shown in FIG. 8, “erase unit” is set as a unit of internal processing.
The erase unit 16 defines the number of unit materials 12 to be erased simultaneously or continuously according to one engraving operation and the relative positional relationship between the unit materials 12 to be erased. For example, 1) an erasing unit 16a made up of a single unit material 12, 2) an erasing unit 16b made up of two upper and lower unit materials 12, and 3) an erasing unit 16c made up of two unit materials 12 arranged in the left-right or front-rear and lateral directions. 4) An erasing unit 16d composed of three unit materials 12 arranged in an L shape vertically and horizontally, and 5) an erasing unit 16e in which four or more unit materials 12 are collected, can be appropriately set.

  One or a plurality of types of erasure units 16 are preset for each target 20, and the types of erasure units 16 applied at that time are rotated at a given change timing as shown in FIG.

  Although the change timing may be set at a fixed period, in the present embodiment, randomness is emphasized, and importance is attached to suddenness that an unexpected amount of chipping occurs in the engraving material 10. Specifically, a plurality of types of erase units 16 (for example, 16b, 16c,...) Comprising a plurality of unit materials 12 are prepared with an erase unit 16a (see FIG. 8) comprising a single unit material 12 as a default. The erasing unit 16 is temporarily changed to a plurality of unit materials 12 for a predetermined time (for example, 5 seconds) at a given timing (for example, selected at random every 10 to 30 seconds). As a result, if a single unit material 12 disappears in a single engraving operation, the unit material 12 disappears all at once at an unexpected timing, and an appropriate game difficulty level is achieved. To do.

  In the present embodiment, the type of the virtual engraving tool 30 can be switched by operating the dial switch 84. The type of the virtual engraving tool 30 is set so that the number of erase units 16 to be erased by one erase operation (engraving operation) is different. For example, a thin blade from which only one erasing unit 16 is erased, a wide blade from which a plurality of erasing units 16 are erased collectively in the lateral direction, and a depth at which a plurality of erasing units 16 are erased together in the tooth tip direction. The blade can be switched. Of course, the type of the virtual engraving tool 30 is not limited to these and can be set as appropriate. The erasing unit 16 is prepared according to the type of the virtual engraving tool 30.

[Description of operation]
Next, the flow of processing in the server system 1100 will be described. The processing flow described here is implemented by the server processing unit 200s executing the server system program 501 and the server program 503.

  16 to 17 are flowcharts for explaining the flow of processing in the server system 1100 of this embodiment. First, as shown in FIG. 16, the server system 1100 first executes a login process (step S2), and prepares new play data 700 for the logged-in user (see FIG. 15).

  Next, the server system 1100 receives a game difficulty level setting (step S4). For example, a game difficulty level option is presented on the touch panel 1108, a player's selection operation input is accepted, and the acceptance result is set to the game difficulty level 704.

  Next, the server system 1100 enters the play field, prompts the player to wear the HMD 6 on the head, hold the controller 8 with one hand, and starts head tracking and controller tracking (step S6). And control which displays a virtual space image (VR image) by HMD6 is started (Step S8). That is, the right-eye virtual camera 36R and the left-eye virtual camera 36L are arranged in the virtual three-dimensional space, and control of these positions and postures synchronized with the head tracking result is started. In addition, the application tool type 740 is initially set to a predetermined type (in this embodiment, a thin blade that erases one erasing unit 16 by one engraving operation), and the virtual engraving tool 30, virtual gripping hand 32, and virtual hitting are performed. The hand 34 is arranged and control of these positions and postures (follow-up control) synchronized with the controller tracking result is started. Then, the image captured by the right-eye virtual camera 36R is displayed as an image for the right eye of the HMD 6 and the image captured by the left-eye virtual camera 36L is displayed as an image for the left eye of the HMD 6.

  Next, the server system 1100 selects the target 20 and presents it to the player (step S10). Specifically, any one is randomly selected from the target definition data 560 (see FIG. 12) of the initial setting data 510 by game difficulty level that matches the game difficulty level 704. Alternatively, the target 20 indicated by the target definition data 560 may be displayed on the HMD 6 so as to be selectable, and the player may select it. The selection result is stored in the play data 700 as the target name 732 (see FIG. 15). Then, the placement control of the target presentation panel 21 (see FIG. 3) is started in the virtual three-dimensional space in order to present the shape and color of the selected target 20 to the player. The target presentation control data 734 is sequentially updated by the arrangement control of the target presentation panel 21.

  Next, the server system 1100 executes engraving material formation processing (step S12).

FIG. 18 is a flowchart for explaining the flow of engraving material formation processing.
In this process, the server system 1100 first determines the application guide level 750 (step S30; see FIG. 15). Basically, the application guide level 750 is set higher as the game difficulty level 730 is lower, but the number of logins is increased so that the player can be regarded as familiar with the game with reference to the login history data 604 of the player (see FIG. 14). If the evaluation is such that the player can be considered skilled with reference to the evaluation result 615 of the work management data 610, the guide level determined according to the game difficulty level 730 is used. However, it is preferable to lower one level. Conversely, when the number of logins is greater than the reference value and the evaluation result 615 is stagnant, the guide level may be increased by one.

  Next, the server system 1100 reads the guide data 566 (see FIG. 13) of the guide level condition 565 to which the determined applied guide level 750 meets, and arranges the guide 14 at a predetermined position in the virtual three-dimensional space (step S32). ). The predetermined position corresponds to the inside of the engraving material 10 to be formed later.

  Next, the shape type of the unit material 12 is determined (step S34). In the present embodiment, the type of the unit material 12 to be used is set in advance by the initial setting data 510 for each game difficulty level (see FIG. 12), but may be selected at random from a plurality of types.

  Next, the arrangement pattern of the unit material 12 is determined (step S36). In the present embodiment, the unit material arrangement pattern 530 of the initial setting data 510 by game difficulty level is uniquely set. However, a plurality of types may be prepared and selected randomly.

  Then, the server system 1100 gradually controls the arrangement of the unit material 12 from the center position of the engraving material 10 toward the outer edge according to the arrangement rule of the unit material arrangement pattern 530 (step S38). Information on the arranged unit material 12 is product model data 754 (see FIG. 15). The player can first see the guide 14 and see the engraving material 10 being formed so that the unit material 12 is buried around the guide 14. Thereby, the player can be aware that the guide 14 that can be seen inside the engraving material 10 should be engraved.

  Next, the server system 1100 accepts a selection input for changing to a guide having a higher guide level than the current guide 14 automatically selected in step S30 in exchange for payment of a given price (step S40).

  If “change guide” is selected (YES in step S42), a payment process is executed (step S44), and the engraving material 10 is discarded (step S46). Then, the guide 14 having a guide level higher than the applied guide level 750 is presented to the player as an option (step S46), the selected guide 14 is arranged (step S48), and the process returns to step S38.

  On the other hand, when “Do not change guide” is selected (NO in step S42), the engraving material forming process is terminated.

  Note that steps S46 to S48 may be replaced with a step in which the server system 1100 automatically selects again the guide 14 corresponding to the guide level one level higher than the applied guide level 750 and rearranges it in the virtual three-dimensional space.

  Returning to FIG. 16, when the formation of the engraving material 10 is completed, the server system 1100 ends the engraving material forming process, and then sets a default erase unit type 760 (see FIG. 15) (step S50). In the present embodiment, an erasing unit 16a (see FIG. 8) made up of a single unit material 12 is installed, but the erasing unit definition data 550 of the engraving material definition data 540 is an erasing device having a small number of unit materials 12 constituting it. The unit 16 may be selected and set.

  Next, when the erasure unit variable setting 543 (see FIG. 12) is set to the variable setting “present” (YES in step S52), the server system 1100 sets the change destination erasure unit type 762, The change timing timer 764 is actuated to start measuring the erase unit change timing (step S54).

  In the present embodiment, the time measured by the change timing timer 764 is selected at random from 10 to 30 seconds, and a predetermined time (for example, 5 seconds: a period during which the change destination erasure unit type 762 is applied). Is set to the time added. The same thing shall be repeated automatically when the timer has completed timing.

  Next, the server system 1100 starts a game (step S56). Accordingly, the time limit 564 (see FIG. 13) is read from the target definition data 560 to which the target name 732 matches, the time limit timer 736 starts measuring time, and the time limit display 22 (see FIG. 3) is displayed. Start control.

  If the change timing of the erasure unit 16 comes after the game starts (YES in step S58), the change destination erasure unit type 762 is rotated from the erasure unit definition data 550 (see FIG. 12) (step S60). At this time, several newly set erasure units 16 are selected from the unit materials 12 of the engraving material 10, their display forms (for example, transparency and color) are changed for about 1 second, and then immediately returned to the original state. An effect that informs the player that the setting of the erasing unit 16 has been changed may be executed.

  Referring to FIG. 17, when the input of the tool type change operation is detected after the game is started, the server system 1100 changes the type of virtual tool associated with the controller 8 (step S66). At this time, when the design of the virtual engraving tool 30 is changed according to the type of tool, it is preferable to display the effect of changing the virtual engraving tool 30 as appropriate.

  Next, the server system 1100 executes engraving production processing (step S68).

FIG. 19 is a flowchart for explaining the flow of engraving production processing in the present embodiment. In this process, the server system 1100 indicates that the type of virtual tool associated with the controller 8 is a sculpture tool (in this embodiment, one of a fine blade, a wide blade, and a deep blade) (YES in step S80). If the input of the engraving operation is detected (YES in step S82), the number of erasure units 16 to be erased collectively per input of the engraving operation according to the type of the associated virtual tool, The relative positional relationship between them is determined (step S84).
Specifically, in the case of a thin blade, the number of erasure units 16 is one. In the case of a wide blade, a plurality of erasing units 16 are used, and the positional relationship is in the horizontal direction. In the case of a deep blade, a plurality of erasing units 16 are set and the positional relationship is set in the tooth tip direction.

  Next, the server system 1100 determines whether the current time is the change timing (step S86). Specifically, in this embodiment, when the time measured by the change timing timer 764 (see FIG. 15) is within the remaining predetermined time (within 5 seconds), an affirmative determination is made.

If it is not the change timing (NO in step S86), the server system 1100 erases the erase unit 16 to be erased with reference to the tip position of the virtual engraving tool 30 based on the determined number and positional relationship of the erase unit 16. Is selected by the type indicated by the default erase unit type 760 (step S88).
On the other hand, if it is the change timing (YES in step S86), the server system 1100 erases the erase unit with reference to the tip position of the virtual engraving tool 30 based on the determined number of erase units 16 and the positional relationship. 16 is selected by the type indicated by the change destination erasure unit type 762 (step S90).

  Then, the server system 1100 erases the unit material 12 included in the erase unit 16 selected in step S88 or S90 (step S92). Accordingly, the data of the deleted unit material 12 is deleted from the product model data 754 (see FIG. 15). It appears to the player's eyes that the engraving material 10 has been cut away.

  On the other hand, when a placement tool is associated with the controller 8 (YES in step S100) and an input of a placement operation is detected (YES in step S102), the server system 1100 uses the tip position of the virtual engraving tool 30 as a reference. Then, a new unit material appears on the outer surface of the engraving material 10 (step S104). Along with this, the data of the unit material 12 that has appeared and added is added to the product model data 754, and it appears to the player's eyes that the engraving material 10 has been arranged.

  Then, the server system 1100 updates the arrangement history data 770 (see FIG. 15) (step S106), and ends the engraving process.

  Returning to FIG. 17, after the start of play, if the coloring tool is associated with the controller 8 (YES in step S100) and a coloring operation input is detected (YS in step S112), the server system 1100 The unit material 12 to be colored is selected on the basis of the tip position of the engraving tool 30 and the display color of the selected unit material 12 is changed (step S114). In the present embodiment, the unit material 12 in a range corresponding to the type of the coloring tool is selected as a coloring target along the surface of the engraving material 10 with the unit material 12 nearest to the tip position of the virtual engraving tool 30 as the center. Then, the product model data 754 (see FIG. 15) is updated with the change in display color.

The server system 1100 repeats steps S58 to S114 until the time measurement by the time limit timer 736 (see FIG. 15) is completed (NO in step S120).
When the time measurement by the time limit timer 736 is completed (YES in step S120), the server system 1100 determines that the time limit for game play has been reached, and executes the product evaluation process (step S122).

FIG. 20 is a flowchart for explaining the flow of the product evaluation process in the present embodiment.
In this process, the server system 1100 first determines a first evaluation point based on the similarity between the contour of the target 20 and the product (step S140). Specifically, the height of the target 20 is matched with the height of the product indicated by the product model data 754, and a six-sided view of the target 20 is generated as the correct image data 780. Is generated as evaluation image data 782. Then, images of the same type (front view in the case of a front view) are read from the correct image data 780 and the evaluation image data 782, and an image similarity determination process for calculating the similarity of contours is executed. The image similarity determination process can be appropriately realized using a known technique. Then, six types of scores for each of the six diagrams are determined so that the higher the similarity is, the higher the score is, and the total is stored in the evaluation score list 784 as the first evaluation score (see FIG. 15).

  Next, the server system 1100 first determines a second evaluation score based on the degree of color similarity between the target 20 and the product (step S142). Specifically, an image similarity determination process is performed in which the same kind of images are read from the correct image data 780 and the evaluation image data 782 and the color similarity is calculated. The image similarity determination process can be appropriately realized using a known technique. Then, six types of scores for each of the six views are determined so that the higher the similarity, the higher the score, and the total is stored in the evaluation score list 784 as the second evaluation score.

  Next, the server system 1100 determines a third evaluation score based on the arrangement history data 770 (see FIG. 15) (step S144). Specifically, the arrangement is regarded as redoing the failed part, and the larger the number of arrangements and the larger the arrangement amount, the larger negative points are set as the third evaluation points.

  Then, the server system 1100 presents the total of the first evaluation score to the third evaluation score to the player as a total evaluation score (step S146), and ends the product evaluation process.

  Returning to FIG. 17, the server system 1100 notifies the end of the game by the HMD 6, removes the HMD 6, returns it to a predetermined position together with the controller 8, and displays a message prompting the player to exit the play field. In addition, since the miniature of the product is output by 3D printing, a display prompting to take it home without fail is displayed (step S160).

  Next, the server system 1100 creates 3D printing model data 786 based on the product model data 754 (see FIG. 15), and the reduced model of the product is three-dimensionally output by the 3D printer 1120 (step S162).

  Then, the server system 1100 creates new work management data 610 (see FIG. 14) in the user management data 600 of the player (step S164), and ends a series of processing.

  When creating the new work management data 610, the play start date 702 of the play data 700 is copied to the creation date 611, and the game difficulty 730 of the play data 700 is copied to the game difficulty 612. The target product name 732 of the play data 700 is copied to the target product name 613, and the product model data 754 of the play data 700 is copied to the product model data 614. In addition, the evaluation result list 784 of the play data 700 is copied to the evaluation result 615, the model data 786 for 3D printing of the play data 700 is copied to the model data 616 for 3D printing, and the play data is included in the product image data 617. 700 evaluation image data 782 is copied.

  As described above, according to the present embodiment, it is possible to provide a new entertainment that realizes a new virtual sculpture technique that can feel the sculpture material being scraped up close and express the sense of play of sculpting more abundantly.

  FIG. 23 is a diagram illustrating a functional configuration example of the server system 1100B of the present embodiment. Basically, it is the same as the server system 1100 of the first embodiment.

  Although examples of programs and data stored in the server storage unit 500s of the server system 1100B of the embodiment are the same as those in the first embodiment (see FIG. 11), the server system 1100B provides a client program to the user terminal 1500. In this case, the client program for distribution is stored as appropriate.

  FIG. 23 is a functional block diagram illustrating an example of a functional configuration of the user terminal 1500 in the present embodiment. The user terminal 1500 of this embodiment includes an operation input unit 100, a terminal processing unit 200, a sound output unit 390, an image display unit 392, a communication unit 394, and a terminal storage unit 500.

  The terminal system program 502 is a program for realizing basic functions of input / output of the user terminal 1500 as a computer.

  The game client program 504 is application software for realizing the function as the user terminal calculation unit 280 by being read and executed by the terminal processing unit 200, and has a configuration incorporated as part of the terminal system program 502. May be.

  Note that the game client program 504 may be a dedicated client program according to a technical technique for realizing an online game, or may be configured by a web browser program and a plug-in that realizes interactive image display.

  The processing in the server system 1100B in this embodiment is basically the same as that in the server system 1100 of the first embodiment. However, in this embodiment, the HMD 6 and the controller 8 are not used, and the game screen is provided as a flat image instead of a VR image, so VR-related steps such as head tracking and controller tracking (for example, step S6 in FIG. 16) are performed. It may be omitted as appropriate, and the display of the VR image may be appropriately read as the display of the game screen. Further, since the server system 1100B of the present embodiment does not include the 3D printer 1120 (see FIG. 1), steps relating to 3D print output can be omitted as appropriate.

  According to the present embodiment, the same effects as those of the first embodiment can be obtained.

[Third Embodiment]
Next, a third embodiment of the present invention will be described.
The present embodiment is basically realized in the same manner as the second embodiment, except that it is executed by a computer system in which a processing subject of game progress control is a user terminal. In the following, differences from the second embodiment will be mainly described, and the same components as those in the second embodiment will be given the same reference numerals and description thereof will be omitted.

  FIG. 25 is a functional block diagram showing a functional configuration example of the user terminal 1500C in the present embodiment. The user terminal 1500 </ b> C of this embodiment includes a game progress control unit 210 in which the game screen display control unit 282 is omitted. In other words, in the present embodiment, the user terminal 1500 executes a calculation process related to the game progress by itself and generates a game space image, that is, a game screen W2 (see FIG. 22).

  Further, the terminal storage unit 500 of the present embodiment stores a terminal system program 502 and a game program 506. As the game progress control unit 210 is processed by the user terminal 1500C, the initial setting data 510 by game difficulty level, the play data 700, and the current date and time 800 are stored in the terminal memory, except for the user management data 600. Stored in unit 500.

  The game program 506 is a program for causing the terminal processing unit 200 to realize the user terminal calculation unit 280, the game progress control unit 210, and the time measurement unit 272 of the present embodiment.

  The processing flow in this embodiment is basically the same as the processing flow of the server system 1100B in the second embodiment. The execution subject of each step may be appropriately replaced with the server system 1100B or the user terminal 1500C as the game progress control unit 210 is executed on the user terminal 1500C. In addition, when executing a process that needs to refer to the user management data 600 such as login at the user terminal 1500C, whether the server system 1100B is requested to provide necessary data or collate, or request the process itself. To deal with.

According to the present embodiment, the same effects as those of the first embodiment can be obtained.
Note that the user terminal 1500C may not be responsible for all of the game progress control unit 210, but may be limited to a part thereof.

[Modification]
As mentioned above, although an example of the embodiment to which the present invention is applied has been described, the form to which the present invention can be applied is not limited to the above form, and additions, omissions, and changes of components can be appropriately made.

  In the above embodiment, the content of the game is a game that enjoys virtual sculpture, but the game genre can be set as appropriate if the game includes virtual sculpture as a game element. For example, a player character's servant beast is created by virtual sculpture in RPG (role-playing game), a present for a love target character is created by virtual sculpture in a love game, or a play tool or food to be nurtured in a training game The present invention can also be applied to scenes and situations where a virtual sculpture is used, or an FPSG (first person shooting game) is used to snip an obstacle to create a retreat path.
