Description

  The present invention relates to an information processing apparatus, a generation program, and a generation method.

  It is known to capture an object such as a character or the like in a virtual space using a virtual camera and draw an object such as an advancing game or an animation character on a screen (see, for example, Patent Document 1).

  In the situation where the virtual camera is fixed, when the character moves in the virtual space and moves out of the area where photographing by the virtual camera is possible, the character appearing on the virtual camera comes off the screen and is not displayed. An object such as a character to be operated in the game needs to be displayed on the screen.

Therefore, the virtual camera is fixed to the stage designed in the virtual space at the time of game development, and a virtual barrier is placed at the boundary between the area where shooting with the virtual camera is possible and the area where shooting is not possible. The character is prevented from going to an area where imaging by the virtual camera is impossible.
However, the arrangement of virtual cameras differs from stage to stage. Therefore, after fixing the virtual camera for each stage at the time of development, the designer creates arrangement information of virtual barriers according to the position of the virtual camera.

JP, 2017-84055, A

  However, there are cases where it is desirable to move the virtual camera without fixing it on each stage. For example, the virtual camera that projects the stage may be moved gently back and forth, or the angle may be changed gradually to increase the image captureable area of the stage, and it is desired to make maximum use of the stage. In such a case, it is cumbersome and impractical for the designer to change the stage design every time the position of the virtual camera is changed. In addition, after the design for each stage by the designer is completed, it may be desired to change the fixed position of the virtual camera to a different position.

  With respect to the above problems, in one aspect, the present invention aims to generate a virtual barrier according to the imaging region of a virtual camera.

  In order to solve the above-mentioned subject, according to one mode, a specification part which specifies a visual frustum which shows an imaging range on virtual space by a virtual camera, and each of a lower surface of the said visual frustum specified, a left surface, and a right surface An information processing apparatus is provided, including: a virtual barrier generation unit that generates a virtual barrier of a predetermined width based on the line of intersection with the ground and places the virtual barrier at a position according to the line of intersection in the virtual space.

  According to one aspect, a virtual barrier can be generated according to the imaging region of the virtual camera.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present specification and the drawings, substantially the same configuration is given the same reference numeral to omit redundant description.

[Information processing device]
An information processing apparatus 10 according to an embodiment of the present invention has a function of executing a game using a character captured by a virtual camera. The information processing apparatus 10 according to the present embodiment can be realized by any electronic device such as a tablet type terminal, a personal computer, a smartphone, a mobile phone, a PDA (Personal Digital Assistants), a game device, and a game portable device. The information processing apparatus 10 may be a wearable display device such as an HMD (Head Mount Display) or an FMD (Face Mount Display).

  As shown in FIG. 1, the information processing apparatus 10 has a display 29. On the display 29, an example of a scene in which the player character PC of the game moves on a certain stage is displayed. In this scene, an example of a scene in which the virtual camera VC (not actually displayed on the display 29) photographs a stage or a field and the player character PC appears on the stage is shown. The position of the virtual camera VC is not limited to this, and images a virtual space from a specific position.

  Hereinafter, a virtual space cut off by the virtual camera is referred to as a “visual camera frustum” or a “visual frustum”. The outermost edge of the area which can be photographed by the virtual camera is the view frustum of the virtual camera. In the example of FIG. 1, the viewing frustum of the virtual camera VC is specified by the right surface RS, the left surface LS, the upper surface US, and the lower surface DS in the forward direction from the focal point F of the virtual camera VC.

  The virtual camera VC, which is the target of generating a virtual barrier in this embodiment, is a virtual camera that shoots a stage or a field (including an open world field), and can be a fixed virtual camera or change of movement or angle Virtual camera. In the following description, the virtual camera VC shoots the stage from a predetermined position.

  The virtual cameras include a virtual camera VC that reflects the stage and a virtual camera that moves following the player character PC. The virtual camera moving following the player character PC is not included in the virtual camera VC which is the target of generating the virtual barrier in the present embodiment. Therefore, when the virtual camera is switched from the virtual camera VC showing the stage to the virtual camera moving following the player character PC, the information processing apparatus 10 does not generate a virtual barrier described later. On the other hand, when the virtual camera is a virtual camera VC shooting a stage or a field, or when the virtual camera moving following the player character PC is switched to the virtual camera VC shooting a stage or a field, the information processing apparatus 10 Create virtual barriers.

[Functional configuration of information processing apparatus]
Next, an example of a functional configuration of the information processing apparatus 10 according to the present embodiment will be described with reference to FIG. The information processing apparatus 10 according to the present embodiment includes a reception unit 7, a game execution unit 8, an imaging unit 9, a specification unit 11, a calculation unit 12, a storage unit 13, a virtual barrier generation unit 14, a determination unit 15, and an image processing unit 16. , Sound processing unit 17, display unit 18, sound output unit 19, and communication unit 20.

  The reception unit 7 receives an operation on the game of the player. For example, the receiving unit 7 receives an input operation performed by the player on the game using an input device such as a controller or a stick. For example, the operation for the game includes an operation for moving the player character. In addition, the reception unit 7 receives information of the player character specified as an example of the “specific object” for generating a virtual barrier described later. When there are a plurality of player characters, the reception unit 7 receives information on a plurality of player characters. Furthermore, when a specific player character is selected from a plurality of player characters, the reception unit 7 receives information on the plurality of player characters and information on the selected player character.

  The game execution unit 8 executes a predetermined game in accordance with the operation received by the reception unit 7.

  The photographing unit 9 photographs a virtual space using the virtual camera VC. The identifying unit 11 identifies a view frustum of the virtual camera VC. The calculating unit 12 calculates the position of a predetermined part of the player character PC, which is an example of the specific object, which is photographed by the virtual camera VC. In the present embodiment, the calculation unit 12 calculates the position of the waist of the player character PC.

  The virtual barrier generation unit 14 generates a virtual barrier having a predetermined width and a predetermined height according to the line of intersection between the bottom surface DS, the right surface RS, and the left surface LS of the identified visual frustum and the ground, It arranges in the position according to the intersection line or the said intersection line. The virtual barrier generation unit 14 regenerates the virtual barrier in response to the movement or change of the angle of the virtual camera VC, and rearranges the virtual barrier in the virtual space. The specific method of generating the virtual barrier will be described later.

  The determination unit 15 determines which one of the virtual camera VC showing the stage and the virtual camera moving following the player character PC is used. When a virtual camera VC showing a stage is used, virtual barrier generation processing is performed.

  When the game execution unit 8 outputs an instruction command to output an image, the image processing unit 16 generates an image of a character corresponding to the instruction command, and outputs the image to the display unit 18. Thereby, the display unit 18 displays the image of the character on the field according to the progress of the game.

  When the game execution unit 8 outputs a sound output instruction command, the sound processing unit 17 generates a sound according to the instruction command and outputs the sound to the sound output unit 19. Thus, the sound output unit 19 outputs sounds such as sounds and sound effects according to the progress of the game. The communication unit 20 communicates with an information processing apparatus such as another game device.

[Hardware configuration of information processing apparatus]
Next, an example of the hardware configuration of the information processing apparatus 10 according to an embodiment of the present invention will be described with reference to FIG. The information processing apparatus 10 according to the present embodiment includes a central processing unit (CPU) 21, a read only memory (ROM) 22, a random access memory (RAM) 23, and a hard disk drive (HDD) 24. Further, the information processing apparatus 10 according to the present embodiment has a graphic card 25, an external I / F (interface) 26, a communication I / F 27, an input I / F 28, a display 29 and a speaker 30. Each part is mutually connected by a bus.

  The ROM 22 is a non-volatile semiconductor memory capable of holding stored programs and data even after the power is turned off. The RAM 23 is a volatile semiconductor memory that temporarily holds programs and data. The HDD 24 is a non-volatile storage device that stores programs and data. The programs stored in the HDD 24 include basic software and application software that control the entire information processing apparatus 10. The HDD 24 may store various databases. The virtual barrier generation program 131 and the game processing program 132 may be stored in the ROM 22, the RAM 23 or the HDD 24. Also, these pieces of information may be stored in a storage device on the cloud that can be connected to the information processing device 10 via the network. The function of the storage unit 13 may be realized by a storage device on the cloud that can be connected to the information processing apparatus 10 via the ROM 22, the RAM 23, the HDD 24, or the network.

  The CPU 21 reads a program and data into the RAM 23 and executes the various processes described above to realize the control of the entire information processing apparatus 10 and the functions incorporated in the information processing apparatus 10. Specifically, the functions of the game execution unit 8 and the photographing unit 9 may be realized by processing that the game processing program 132 installed in the information processing device 10 causes the CPU 21 to execute. The functions of the identifying unit 11, the calculating unit 12, the virtual barrier generating unit 14, and the determining unit 15 may be realized by processing that the virtual barrier generation program 131 installed in the information processing apparatus 10 causes the CPU 21 to execute.

  The external I / F 26 is an interface that connects the information processing device 10 to an external device. The external device is, for example, a storage medium 26a. Thereby, the information processing apparatus 10 reads data from the storage medium 26 a and writes data to the storage medium 26 a via the external I / F 26. Examples of the storage medium 26a include a CD (Compact Disk), a DVD (Digital Versatile Disk), an SD memory card (SD Memory card), a USB memory (Universal Serial Bus memory), and the like.

  For example, the information processing apparatus 10 can be equipped with a storage medium 26 a in which game programs such as the virtual barrier generation program 131 and the game processing program 132 are stored. These programs are read by the external I / F 26 and read into the RAM 23.

  The CPU 21 processes the various programs read into the RAM 23 and instructs the graphic card 25 to output an image corresponding to the progress of the game. The graphic card 25 performs image processing of a character or the like on the field displayed on the screen in accordance with the instruction, and causes the display 29 to draw an image of the character or the like. One frame time of the image output from the graphic card 25 is, for example, 1/30 to 1/60 seconds. The graphic card 25 executes drawing of one image in frame units. That is, images of 30 to 60 frames are drawn per second. The function of the image processing unit 16 can be realized by, for example, the graphic card 25. The function of the display unit 18 may be realized by, for example, the display 29.

  Further, the CPU 21 processes the various programs read into the RAM 23 and causes the speaker 30 to output a predetermined sound as the game progresses. The function of the sound processing unit 17 can be realized, for example, by the CPU 21 executing the various programs read into the RAM 23. The function of the sound output unit 19 may be realized by the speaker 30, for example.

  The communication I / F 27 is an interface for connecting the information processing apparatus 10 to a network. Also, the communication I / F 27 may have a function of communicating with other game devices via a communication unit having an antenna. The function of the communication unit 20 can be realized by, for example, the communication I / F 27.

  The input I / F 28 is an interface connected to the controller 1. The controller 1 has an operation button 2 and a direction key 3. The player can move the player character in a predetermined direction by operating the operation button 2 and the direction key 3 to perform a predetermined action such as an attack. The input I / F 28 causes the RAM 23 to store input information based on an input operation performed by the player using the controller 1. The CPU 21 executes various arithmetic processing related to the motion of the player character based on the input information stored in the RAM 23. The function of the reception unit 7 can be realized by, for example, the input I / F 28.

  The display 29 may have the touch panel 31 mounted thereon. Thereby, input operation can be performed without using the controller 1. In this case, the input information on the touch position detected by the touch panel 31 may be stored in the RAM 23, and the CPU 21 may execute various arithmetic processing based on the input information stored in the RAM 23.

[Barrier generation processing]
Next, an example of the barrier generation process according to an embodiment will be described with reference to FIG. FIG. 4 is a flowchart showing an example of barrier generation processing (main processing) according to an embodiment.

  Note that, before the present process is started, the determination unit 15 determines which of the virtual camera VC projecting the stage and the virtual camera moving following the player character PC is used. When the virtual camera VC that reflects the stage is used, this process is started.

  When the present process is started, first, the receiving unit 7 determines whether an operation to start the game has been received (step S10). When the reception unit 7 receives an operation to start the game, the game execution unit 8 starts the game, and the specification unit 11 specifies a viewing frustum of the virtual camera VC (step S12). Next, the virtual barrier generation unit 14 executes a process of generating a virtual barrier on the lower surface DS of the viewing frustum (step S14).

(Virtual barrier generation processing of the lower surface DS)
A process of generating a virtual barrier of the lower surface DS of the viewing frustum will be described with reference to FIGS. 5 and 6. FIG. 5 is a flowchart showing an example of the barrier generation process of the lower surface DS according to an embodiment. FIG. 6 is a view showing an example of a virtual barrier of the lower surface DS according to an embodiment.

  FIG. 5 is called in the process of S14 of FIG. In FIG. 5, the calculation unit 12 calculates an intersection line between the bottom surface DS of the identified visual frustum and the ground. The virtual barrier generation unit 14 generates a virtual barrier having a predetermined width and a predetermined height according to the intersection line, and arranges the virtual barrier at a position passing the waist of the player character PC parallel to the calculated intersection line (step S26) ), End this processing.

  According to this, as shown in FIG. 6, the waist position SP of the player character PC located on the intersection of the display 29 is calculated. In the example of FIG. 6, the identified viewing frustum is shown by the perspective view of upper surface US, lower surface DS, right surface RS, and left surface LS. For example, when the virtual camera VC is disposed parallel to the ground, the upper surface US is disposed at an angle of 30 ° upward from the focal point F with respect to the line 0 parallel to the ground, and 30 ° downward from the focal point F The lower surface DS is disposed at an angle.

  By the processing shown in FIG. 5, a virtual barrier Cd having a predetermined width and a predetermined height, which passes through the waist of the player character PC, is generated and arranged in parallel to the intersection GM of the lower surface DS of the viewing frustum and the ground. However, the virtual barrier Cd is invisible to the game player. The virtual barrier Cd is a virtual barrier for suppressing the movement range of the player character PC so that the player character PC is not positioned lower than the virtual barrier Cd. As a result, it is possible to prevent the player character PC from being framed out from the virtual space and being out of the screen.

  Returning to FIG. 4, subsequently, the virtual barrier generation unit 14 executes a process of generating virtual barriers on the right surface RS and the left surface LS of the viewing frustum (step S16).

(Virtual barrier generation processing for right surface RS and left surface LS)
A process of generating virtual barriers on the right surface RS and the left surface LS of the viewing frustum will be described with reference to FIGS. 7 and 8. FIG. 7 is a flowchart illustrating an example of barrier generation processing of the left surface LS and the right surface RS according to an embodiment. FIG. 8 is a diagram illustrating an example of virtual barriers of the left surface LS and the right surface RS according to an embodiment.

  FIG. 7 is called in the process of S16 of FIG. In FIG. 7, the determination unit 15 determines whether the right surface RS of the viewing frustum is inclined (step S <b> 30). In addition, "inclination of right surface RS of a viewing frustum" means a roll of a camera.

  If the determination unit 15 determines that the right surface RS of the viewing frustum is perpendicular to the ground and there is no inclination, the calculation unit 12 proceeds to step S34, and intersects a plane including the right surface RS of the viewing frustum and the ground. Calculate the line.

  In step S30, when the determination unit 15 determines that the right surface RS is not perpendicular to the ground and has an inclination, the calculation unit 12 determines that the right surface RS of the viewing frustum is perpendicular to the ground without inclination. It substitutes to RS (step S32). Next, the calculation unit 12 proceeds to step S34, and calculates an intersection line between a plane including the right surface RS of the replaced view frustum and the ground.

  Next, the virtual barrier generation unit 14 generates and arranges a virtual barrier having a predetermined width and a predetermined height having the same normal as the surface normal of the right surface RS of the frustum on the calculated intersection line (Step S36).

  Note that "the same normal as the surface normal of the right surface RS of the viewing frustum" means the same normal as the surface normal directed to the ground and perpendicular to the right surface RS.

  As a result, as shown in an example in FIG. 8, virtual barriers Cr having a predetermined width and a predetermined height are generated and arranged on the intersection line LR between the right surface RS and the ground. However, the virtual barrier Cr is invisible to the game player. The virtual barrier Cr is a virtual barrier for suppressing the movement range of the player character PC so that the player character PC is not positioned on the right side of the virtual barrier Cr. As a result, it is possible to prevent the player character PC from being framed out from the virtual space to the right and not being removed from the screen.

  Returning to FIG. 7, next, the calculation unit 12 calculates an intersection line between a plane including the left surface LS of the viewing frustum and the ground (step S38). Next, the virtual barrier generation unit 14 generates and arranges a virtual barrier having a predetermined width and a predetermined height having the same normal as the surface normal of the left surface LS of the viewing frustum on the calculated intersection line (Step S40). Thus, the present process ends.

  Note that "the same normal to the surface normal of the left surface LS of the viewing frustum" means the same normal to the surface normal to the ground and directed to the ground.

  As a result, as shown in FIG. 8, a virtual barrier Cl having a predetermined width and a predetermined height is generated and arranged on the intersection line LP between the left surface LS of the identified frustum and the ground. However, the virtual barrier Cl is invisible to the game player. The virtual barrier Cl is a virtual barrier that suppresses the motion of the player character PC so that the player character PC is not positioned on the left side of the virtual barrier Cl. As a result, it is possible to prevent the player character PC from being framed out from the virtual space to the left and disappearing from the screen.

  Returning to FIG. 4, next, the photographing unit 9 photographs a virtual space using the virtual camera VC (step S18). At this time, from the virtual barrier Cd corresponding to the lower surface DS of the viewing frustum of the virtual camera VC, the virtual barrier Cr corresponding to the right surface RS, and the virtual barrier Cl corresponding to the left surface LS, the player character PC is a virtual camera VC Frame out outside and never disappear. Thus, the player character PC is always displayed on the display 29.

  Next, the determination unit 15 determines whether the game is over (step S20). If the determination unit 15 determines that the game is over, the present process ends. If the determination unit 15 determines that the game has not ended, the determination unit 15 determines whether the virtual camera VC has moved or changed the angle (step S22). If it is determined that the virtual camera VC has not moved and the angle has not been changed, the determination unit 15 returns to step S18, continues shooting using the virtual camera VC, and advances the game.

  On the other hand, when the determination unit 15 determines in step S22 that the virtual camera VC has moved or changed the angle, the specification unit 11 specifies a viewing frustum of the virtual camera VC after the movement or the angle change ( Step S24). Next, the virtual barrier generation unit 14 executes a process of generating a virtual barrier of the lower surface DS of the viewing frustum (step S26). The process of generating the virtual barrier of the lower surface DS of the viewing frustum has been described in step S14, and thus the description thereof is omitted here.

  Next, the virtual barrier generation unit 14 executes a process of generating virtual barriers on the right surface RS and the left surface LS of the frustum (step S28). The process of generating the virtual barriers of the right surface RS and the left surface LS of the viewing frustum has been described in step S16, and thus the description thereof is omitted here.

  For example, as shown in FIG. 9, when the virtual camera VC is rotated and the angle of the virtual camera VC is changed, the processing in steps S24 to S28 is performed to regenerate the virtual barrier. Then, the regenerated virtual barriers are rearranged from the position of the dotted virtual barriers Cd, Cr, and Cl before the virtual camera VC rotates to the position of the solid virtual barriers Cd, Cr, and Cl after the rotation.

  For example, in a scene in which a virtual camera VC is fixed and shooting a certain stage but the player character PC enters from the left end of the stage and comes out from the right end, even if the virtual camera VC is zoomed out, There are times when you can not project both. In this case, the camera angle may be changed gradually. Also in such a case, according to the present embodiment, the entire stage can be photographed by gradual angle change or gradual movement of the virtual camera VC, and virtual barriers Cd and Cr according to the movement of the virtual camera VC. By regenerating and rearranging C1, and Cl, it is possible to prevent the player character PC from disappearing from the screen.

  Next, the process returns to step S18, the photographing is continued by the virtual camera VC, the game is advanced, and the processes of steps S18 to S28 are repeated until the game is finished in step S20. The virtual barriers Cd, Cr, and Cl may have a rectangular parallelepiped shape, a plate shape, or any other shape.

  In the past, designers designing stages at the time of development designed virtual barriers according to the frustum of a virtual camera that mirrors the stage. At this time, after the stage design is completed, if the developer wants to change the position of the virtual camera VC reflecting the stage, the information on the designed virtual barrier can not be used, and the developer responds to the changed position of the virtual camera VC. Designers have once again designed virtual barriers.

  On the other hand, according to the present embodiment, a virtual barrier is generated according to the arrangement or rearrangement of the virtual camera VC. Thereby, even if the virtual camera VC is arranged or rearranged, it can be avoided that the player character PC disappears from the screen. Also, when moving or changing the angle of the virtual camera VC, a virtual barrier corresponding to the position of the virtual camera VC after moving or changing the angle is regenerated. This makes it possible to prevent the player character PC from disappearing from the screen even if the virtual camera VC is moved.

  This saves the designer the time and effort of designing the position of the virtual barrier, and can improve the development efficiency and shorten the development time. Further, according to the present embodiment, movement and angle change of the virtual camera VC can be freely performed on the stage. As a result, while ensuring that the player character PC is not lost when the virtual camera VC is fixed or the virtual camera VC is moved gently, the degree of freedom in game design is increased, and game development is facilitated.

  In the present embodiment, the virtual barrier is not arranged on the upper surface US of the view frustum of the virtual camera VC. The reason is that since the upper surface US does not intersect the ground, imaging is possible to infinity, and there are few scenes for arranging virtual barriers. That is, it is difficult to assume that the player character PC can be drawn anywhere on the depth side of the upper surface US, and the player character PC disappears from the front side of the upper surface US. As described above, in addition to the fact that the player character PC can be continued to be displayed without arranging the virtual barrier on the upper surface US, there are many scenes in which a large wall is previously arranged on the depth side of the screen. Thus, the motion of the player character PC is restricted. From the above, the load on the virtual barrier generation process can be reduced by not arranging the virtual barrier on the top surface US. However, a virtual barrier may be disposed on the upper surface US.

  In the present embodiment, a virtual barrier of the lower surface DS of the viewing frustum is generated on the basis of the position SP of the waist of the player character PC. The reason for using the position of the waist of the player character PC as a reference is to ensure that when the player character PC comes to the front of the screen, a video above the waist of the player character PC is displayed. This is because the natural state of the player character PC can be drawn. However, the position of the predetermined part of the specific object is not limited to the position of the waist of the character, and may be any part such as the position of the foot, the position of the hip, the position of the knee, and the position of the shoulder. Even when the specific object is not a character, a virtual barrier of the lower surface DS of the viewing frustum can be generated on the basis of the position of a predetermined part of the specific object.

  In the above description, the player character PC has been described as an example of the specific object. The reason is to guarantee that the player character PC continues to be displayed on the screen. However, the specific object is not limited to this. For example, if there is a float object such as a balloon in front of the character displayed on the display 29, and you do not want the float object to be framed out of the virtual camera VC, the position of the float object Virtual barriers may be generated on the basis of The virtual barrier in this case may be ring-shaped or ball-shaped.

  The specific object may be a plurality of characters or a plurality of objects. For example, when a specific object is a plurality of characters, a virtual barrier having a predetermined width and a predetermined height is generated and arranged on a line passing through the position of a predetermined part of any one character selected or automatically selected by the player. You may

Matters described in the above plurality of embodiments can be combined without contradiction.
