Description

    The present invention relates to game software using a two-dimensional image obtained by shooting a live action, and in particular, when a spotlight is irradiated on a two-dimensional image using a spotlight irradiation device such as a flashlight in a game. The present invention relates to game software and a game apparatus capable of displaying a light wheel in a three-dimensional manner.

  In this specification, “game software” is a concept including the program itself and various data associated with the program as necessary. However, “game software” does not necessarily have to be associated with data, but a program always exists. The “various data associated with each other” may be stored in a memory means such as a ROM disk together with a program, and further stored in an external memory means so as to be readable via communication mediating means such as the Internet. It may be.

    Conventionally, as this type of game software, a field is configured by a three-dimensional virtual space while a character has a spotlight lighting device such as a flashlight and illuminates the surroundings of the character with a spotlight irradiated by the irradiation device. A game that moves around and encounters items and monsters is well known.

    Note that the numbers in parentheses are for the sake of convenience indicating the corresponding elements in the drawings, and therefore the present description is not limited to the descriptions on the drawings.

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

  FIG. 1 is a control block diagram of a game machine to which the present invention is applied, and FIG. 2 is a schematic diagram showing an example of a plate-like polygon and a character mapped with a two-dimensional photographic image arranged in a three-dimensional virtual space. 3 is a schematic diagram showing a state in which the 3D model corresponding to the subject of the 2D photographic image of FIG. 2 is arranged in the 3D virtual space, and FIG. 4 is a 3D halo generated by the 3D model. FIG. 5 is a schematic view showing a state in which a two-dimensional halo image is set to a plate-like polygon on which a two-dimensional photographic image is mapped.

    As shown in FIG. 1, the game apparatus 20 executes a predetermined game in accordance with game software such as an adventure game recorded on a ROM disk 15 as a recording medium. The game device 20 includes a CPU 1 mainly composed of a microprocessor, a ROM 2 and a RAM 3 as main storage devices for the CPU 1, an image processing device 4 and a sound processing device 6, and buffers 5 and 7 for these devices. And a ROM disk reader 8. In the ROM 2, an operating system is written as a program necessary for overall operation control of the game machine. In the RAM 3, a game program and data read from the ROM disk 15 as a storage medium are written as necessary. The image processing device 4 receives the image data from the CPU 1 and draws the game screen on the frame buffer 5, converts the drawn image data into a predetermined video reproduction signal, and outputs it to the monitor 9 at a predetermined timing. . The sound processing device 6 reproduces data such as voice and musical sound, sound source data, and the like read from the ROM disk 15 and recorded in the sound buffer 7 and outputs them from the speaker 10. The ROM disk reader 8 reads a program or data recorded on the ROM disk 15 in accordance with an instruction from the CPU 1 and outputs a signal corresponding to the read content. The ROM disk 15 stores game software including programs and data necessary for game execution. The monitor 9 generally uses a home television receiver, and the speaker 10 generally uses a built-in speaker of the television receiver.

    Further, a communication control device 11 is connected to the CPU 1 via a bus 14, and a controller 12 and an auxiliary storage device 13 as input devices are detachably connected to the device 11 via appropriate connection ports. The controller 12 functions as an input device, and is provided with operation members such as operation keys for accepting operations by the player. The communication control device 11 scans the operation state of the controller 12 at a constant cycle (for example, 1/60 seconds), and outputs a signal corresponding to the scanning result to the CPU 1. The CPU 1 determines the operation state of the controller 12 based on the signal. A plurality of controllers 12 and auxiliary storage devices 13 can be connected to the communication control device 11 in parallel.

    In the above configuration, the other components excluding the monitor 9, the speaker 10, the controller 12, the ROM disk 15, and the auxiliary storage device 13 are integrally accommodated in a predetermined housing to constitute the game machine body 16. The game machine body 16 functions as a computer.

    In the game device 20 having the above-described configuration, games of various genres can be played on the screen of the display 9 by loading the program recorded on the ROM disk 15 into the RAM 3 and executing it by the CPU 1.

    In the game device 20, when a predetermined initialization operation (for example, a power-on operation) is performed, the CPU 1 first executes a predetermined initialization process according to the program in the ROM 2. When the initialization is completed, the CPU 1 starts reading the game software GPR stored in the ROM disk 15, and starts game processing according to the program. When the player operates the controller 12, which is an input device, to perform a predetermined game start operation, the CPU 1 starts various controls necessary for executing the game according to the procedure of the game software GPR.

  Note that, as an example of the computer that causes the game software according to the present invention to function, the game apparatus 20 as a home game machine has been described as an example. However, the game apparatus 20 may be a so-called portable game machine. Not only a game-dedicated device, but also a device capable of playing back general music and video recording media. The computer is not limited to this, and any computer may be used, for example, a personal computer, a mobile phone, or the like, that is, any computer that can function the game software.

  As long as various programs and various data constituting the game software GPR are freely readable by the program function of the game software GPR, the storage mode is arbitrary, as in this embodiment. In addition to being stored in the ROM disk 15 together with the game software GPR program, the game software GPR is stored in an external memory means such as a server independent of the game machine 1 and is read by a read program provided in the game software GPR. Alternatively, the information may be downloaded to a memory such as the RAM 3 via communication mediating means such as the Internet.

    As shown in FIG. 2, the game by the game software GPR is played on the field FLD set in the three-dimensional virtual space 31 generated by the CPU 1 in the RAM 3 by the field generation program FPP of the game software GPR. However, it is set as a so-called adventure game in which a character 30 that can be operated via the controller 12 moves and searches for various items to solve a mystery. The character 30 is composed of a three-dimensional polygon model composed of three-dimensional polygons.

    In the game software GPR shown in FIG. 1, only software elements related to the present invention constituting the game software GPR are described, and the game software GPR describes in FIG. In addition to the above, various programs and data necessary for executing a game using the game software GPR are stored.

    In the three-dimensional virtual space 31, the CPU 1 uses the background processing program BTP of the game software GPR to place one plate-shaped polygon 60 at a predetermined coordinate position (in the case of FIG. In order to do this, an XY coordinate plane is set at a position away from the character 30 arranged in the three-dimensional virtual space 31 by a predetermined distance in the Z-axis direction that is the camera's line of sight, and the Z = constant fourth quadrant The plate-like polygon 60 is mapped with a live-action two-dimensional photographic image PIC corresponding to the development of the game scenario. The two-dimensional photographic image PIC is composed of a live-action image obtained by photographing a real three-dimensional subject.

    It should be noted that the number of plate-like polygons 60 and their arrangement positions with respect to the character 30 in the three-dimensional virtual space 31 are completely arbitrary and can be variously modified.

    In the two-dimensional photographic image PIC, for example, in the case of FIG. 2, planar objects such as a floor 63, walls 62A, 62B, 62C, and a ceiling 65 inside the building are captured. Here, as is apparent from the drawing, the wall 62C is located at the deepest position of the walls 62A and 62B on both sides in the parallel state, and any of the walls 62A, 62B and 62C is located with respect to the floor 63. The state of being arranged in an intersecting manner is taken. In addition, the state in which the ceiling 65 is arranged in a shape that intersects the walls 62A, 62B, and 62C in a direction parallel to the floor 63 is photographed on the upper portions of the walls 62A, 62B, and 62C.

    And in the part where the floor 63, the walls 62A, 62B, 62C, and the ceiling 65, which are these planar elements, cross each other, a boundary line 67 indicating the boundary between each other is between the floor 63 and the walls 62A, 62B, 62C. , Necessarily between the walls 62A and 62B, between the walls 62B and 62C, and between the ceiling 65 and the walls 62A, 62B and 62C, and these are also imprinted as part of the two-dimensional photographic image PIC. Yes.

    As the planar element imprinted on the two-dimensional photographic image PIC, various elements are conceivable depending on the subject of the two-dimensional photographic image PIC. However, the planar element is not limited to a plate-like element, and may be a curved one. In general, in addition to the floors, walls, and ceilings described above, the ground, roads, outer peripheral surfaces of columns of buildings, outer peripheral surfaces of beams, outer wall surfaces, surfaces of steps constituting steps, glass surfaces, sky, The water surface, the outer surface of the trunk of a large tree, the outer surface of the block, the surface of the revetment, the various outer surfaces that make up the structure, etc. can be considered, and there are various other factors.

    As shown in FIG. 1, the game software GPR has a two-dimensional photo image file DPF in which a large number of two-dimensional photo images PIC are stored, and the background processing program BTP is a scenario during the game via the CPU 1. According to the development, the corresponding two-dimensional photographic image PIC can be read from the two-dimensional photographic image file DPF and mapped to the plate-like polygon 60 in the three-dimensional virtual space 31 as shown in FIG.

    In this way, when a certain two-dimensional photographic image PIC is mapped to the plate-like polygon 60, the two-dimensional photographic image PIC that is actually captured is mapped to the field FLD in the three-dimensional virtual space 31, as shown in FIG. The plate-like polygon 60 is arranged in front of the character 30, and an image of the plate-like polygon 60 and the character 30 viewed from a predetermined camera line of sight Z is displayed on the CPU 1 by the display image generation program DPP of the game software GPR. And generated as two-dimensional display image data PDT and output to the image processing apparatus 4.

    The image processing device 4 generates an image to be displayed on the monitor 9 in the frame buffer 5 based on the output two-dimensional display image data PDT, and the monitor 9 displays the image so that the character 30 is displayed. A two-dimensional photographic image PIC is displayed in the background in the three-dimensional virtual space 31.

    The character 30 in the three-dimensional virtual space 31 is a plate-shaped polygon on which a two-dimensional photographic image PIC is mapped by the game software GPR based on the operation of the player via the controller 12 as shown in FIG. Although the movement is controlled in front of the camera 60, the state is generated by the display image generation program DPP through the CPU 1 as an image viewed from the camera line of sight Z. On the monitor 9, the character 30 is changed to a plate-like polygon 60. An image that moves around in front of the mapped two-dimensional photographic image PIC is displayed.

    In this game, the brightness of the 2D photographic image PIC set in the 3D virtual space 31 is set to be dark, and the player cannot recognize the situation around the character 30 as it is. A spotlight irradiator 32 such as a flashlight that is set to be possessed by the character 30 in the three-dimensional virtual space 31 is connected to the irradiator operation program LHP in the game software GPR via the controller 12 and the CPU 1. As necessary. The spotlight LT1 generated by the spotlight irradiation tool 32 operated by the irradiation tool operation program LHP is generated in the form of an object in a three-dimensional virtual space, for example, as shown in FIG. 5 by the display image generation program DPP.

    The display image generation program DPP further captures the character 30 (including the spotlight irradiation device 32), the spotlight LT1, the two-dimensional photographic image PIC, and the like in the three-dimensional virtual space as camera images from a predetermined camera line of sight Z. A display image is generated and displayed on the monitor 9 via the image processing device 4 or the like.

    Then, the monitor 9 displays a camera image in which the character 30 carrying the spotlight irradiation device 32 is irradiating the subject with the spotlight LT1 in front of the subject displayed in the two-dimensional photographic image PIC. .

    The game software GPR is a halo formed by the light of the spotlight LT1 at the intersection of the spotlight LT1 irradiated from the spotlight irradiation instrument 32 and the plate-shaped polygon 60 via the display image generation program DPP. The 61 portion is displayed brighter than the surroundings and displayed on the monitor 9 via the image processing device 4. The player advances the game while watching the video of the two-dimensional photographic image PIC displayed on the monitor 9 brighter than the surroundings by the halo 61.

    At this time, the display image generation program DPP sets the halo 61 of the spotlight LT1 on the two-dimensional photographic image PIC mapped to the plate-like polygon 60 to generate the display, and the display image generation program DPP The shape of the halo 61 to be mapped to the plate-like polygon 60 is calculated via the CPU 1.

    In response, the halo image generation program LSP corresponds to the 2D photographic image PIC currently mapped to the plate-like polygon 60 from the 3D model file TMF stored in the game software GPR via the CPU 1. The three-dimensional model 3DM is read out and placed in the three-dimensional virtual space 31.

    The three-dimensional virtual space in which the three-dimensional model 3DM is arranged is not necessarily the same space as the three-dimensional virtual space 31 in which the plate-like polygon 60 is arranged, and the character 30 and the plate-like polygon are not necessarily provided. As long as the arrangement relation corresponding to the arrangement relation of 60 can be reproduced between the three-dimensional model 3DM and the character 30, it can be arranged in another three-dimensional virtual space different from the three-dimensional virtual space 31.

    The 3D model file TMF stores 3D models 3DM corresponding to all the 2D photographic images PIC used by mapping to the plate-like polygon 60 by the game software GPR, and is currently plate-shaped. The 3D model 3DM corresponding to the 2D photographic image PIC mapped to the polygon 60 can be immediately read from the 3D model file TMF.

    As shown in FIG. 3, the three-dimensional model 3DM includes main planar elements from a subject photographed as a live-action image on a two-dimensional photographic image PIC currently mapped to a plate-shaped polygon 60. These are extracted and modeled along with the boundary lines of these planar elements. That is, the three-dimensional model 3DM is a model obtained by modeling a subject captured in a two-dimensional photographic image PIC as a three-dimensional object, and is a simplified three-dimensional model of an actual subject.

    More specifically, the three-dimensional model 3DM shown in FIG. 3 corresponds to the two-dimensional photographic image PIC shown in FIG. 2, and is taken into the real image of the two-dimensional photographic image PIC shown in FIG. A plurality of planar elements FF, that is, a floor 63, walls 62A, 62B, and 62C, a ceiling 65, and a boundary line 67 that indicates a portion where these planar elements FF intersect are arranged in a two-dimensional photographic image PIC. The three-dimensional virtual space 31 is replaced with a three-dimensional model 3DM composed of a plurality of model frames MF and a plurality of linear frames FR indicating portions where they intersect in the three-dimensional virtual space 31 in a form corresponding to the state. It was constructed and created.

    That is, the lower surface 63M corresponds to the wall 62A, the wall surface 62AM corresponds to the wall 62B, and the wall surface 62BM corresponds to the wall 62B in the three-dimensional model 3DM corresponding to the floor 63 of the two-dimensional photographic image PIC in FIG. A wall surface 62CM is provided as a model surface MF corresponding to the wall 62C, and an upper surface 65M is provided as a model surface MF corresponding to the ceiling 65. And the boundary line 67 which shows the part which each planar element FF of the two-dimensional photographic image PIC crosses is provided as the linear frame FR.

    Each model plane MF in the three-dimensional virtual space 31 corresponds to the perspective relationship of each planar element FF displayed by the two-dimensional photographic image PIC, that is, corresponding to the actual subject captured in the two-dimensional photographic image PIC. In the three-dimensional virtual space 31, the wall surface 62CM corresponding to the wall surface C is configured to be arranged at a position farthest from the camera line of sight Z in the three-dimensional model 3DM, and the three-dimensional virtual space 31 of the three-dimensional model 3DM. Various dimensions such as the dimension L in the depth direction and the frontage dimension W are set so as to correspond to the actual dimensional relationship of each planar element FF constituting the two-dimensional photographic image PIC, that is, the actual dimension of the subject. ing. For example, the frontage dimension W of the three-dimensional model 3DM is set corresponding to the actual width WR of the floor 63 displayed in the two-dimensional photographic image PIC as the subject, and the dimension in the depth direction of the three-dimensional model 3DM. L is set corresponding to the depth of the floor 63 of the actual subject.

    In other words, the three-dimensional model 3DM is modeled in a form corresponding to the actual dimensions of the subject constituting each two-dimensional photographic image PIC.

    In this way, the 3D model 3DM and the character 30 corresponding to the 2D photographic image PIC mapped to the plate-like polygon 60 are arranged between the 2D photographic image PIC and the character 30 mapped to the plate-like polygon 60. When an arrangement corresponding to the relationship is arranged in the three-dimensional virtual space 31 by the CPU 1, the halo image generation program LSP is emitted from the spotlight illuminating device 32 that is input by the player via the controller 12. The direction of the light LT1 is calculated, the intersection of the spotlight LT1 and the model plane MF constituting the three-dimensional model 3DM is calculated, and the shape of the light wheel 61DM generated when the spotlight LT1 is irradiated onto the three-dimensional model 3DM Is calculated. This shape is naturally calculated as a three-dimensional shape having three-dimensional coordinates.

    When the spotlight LT1 is irradiated onto a three-dimensional object in the three-dimensional virtual space, the calculation method of the shape of the halo 61DM generated in the three-dimensional object can be easily obtained by various known methods. In the case of FIG. 3, the halo image generation program LSP generates the three-dimensional virtual space 31 in accordance with the optical axis CL of the spotlight LT1 irradiated from the spotlight irradiator 32 of the character 30 (instructions from the player via the controller 12). A virtual plane PL perpendicular to the optical axis CL is set at a position separated by a predetermined distance L2 from the position of the spotlight irradiation tool 32, and the spotlight irradiated from the spotlight irradiation device 32 is set on the virtual plane PL. The basic optic wheel 61A of LT1 is arranged.

    The basic halo 61A may adopt any shape depending on the characteristics of the spotlight illuminating device 32 set in the game, but in the case of FIG. 3, it is set to a circle having a radius r. Yes. In this state, the halo image generation program LSP sets a large number of points PT at a predetermined interval L3 on the contour line CNF of the basic halo 61A, and connects the points PT and the emission center point CTP of the spotlight illuminating device 32. The segment LN is set, the intersection point CP between the line segment LN and each model plane MF of the three-dimensional model 3DM is calculated, and the intersection point CP is connected to each other to obtain the halo 61DM on the three-dimensional model 3DM.

    A three-dimensional model 3DM is a three-dimensional model of a subject captured in a two-dimensional photographic image PIC mapped to a plate-like polygon 60, and a character 30 (spot (spot) in the three-dimensional virtual space 31 is obtained. A light irradiation device 32) and a two-dimensional photographic image PIC mapped to the plate-like polygon 60, and a character 30 (including the spotlight irradiation device 32) in the three-dimensional virtual space 31. The positional relationship between the three-dimensional model 3DM and the character 30 that is normally assumed from the subject displayed by the two-dimensional photographic image PIC is also matched so as not to be unnatural. Since the parameters are set as attribute data of each three-dimensional model 3DM, the shape of the halo 61DM calculated on the three-dimensional model 3DM is If the subject captured in the three-dimensional photographic image PIC is actually generated by a polygon model or the like in the three-dimensional virtual space 31, the shape that will be generated by the spotlight LT1 irradiated by the character 30 is exhibited. It will be.

    That is, when the character 30 irradiates a specific part of the two-dimensional photographic image PIC with the spotlight LT1, the spotlight LT1 is irradiated to a corresponding part on the three-dimensional model 3DM. It is formed in a part on the three-dimensional model 3DM corresponding to the part irradiated with the spotlight LT1 on the two-dimensional photographic image PIC.

    Next, the halo image generation program LSP calculates the coordinate value in the three-dimensional virtual space 31 of the halo 61DM on the three-dimensional model 3DM, and further, as shown in FIG. Projection processing is performed in the camera sight line Z direction on the coordinate plane in which the plate-like polygon 60 in the virtual space 31 is set, that is, the XY plane (Z = constant), and the two-dimensional area indicated by hatching in the figure. The figure of the halo 61 is obtained.

    Thus, the halo 61DM on the three-dimensional model 3DM is projected in the camera viewing direction Z, which is a generation direction of a two-dimensional image as a camera image that the player can see through the monitor, and is a natural view seen from the player side. It is possible to obtain the shape of the halo 61 having a two-dimensional display.

    In the case of FIG. 4, the coordinate position of the wall surface 62CM of the three-dimensional model 3DM is made to coincide with the coordinate position where the plate-like polygon 60 of the three-dimensional virtual space 31 is arranged. However, the plane on which the three-dimensional halo 61DM is projected does not have to coincide with the coordinate position where the plate-shaped polygon 60 is disposed, but the polygon projected by the projection onto the plane parallel to the plate-shaped polygon 60 60 is desirable because it can be easily associated with the two-dimensional photographic image PIC 60.

    In this state, the display image generation program DPP is an image obtained by viewing the two-dimensional photographic image PIC, the character 30 and the spotlight LT1 mapped to the plate-like polygon 60 from the camera line of sight Z via the CPU 1, that is, the camera image. As shown in FIG. 5, a two-dimensional halo 61 obtained by projecting in the camera sight line Z direction at a position corresponding to the part irradiated with the spotlight LT1 on the camera image is set as shown in FIG. A process of increasing the brightness of the camera image in the portion surrounded by the halo 61 more than the other portions is performed. The display image generation program DPP displays the camera image thus obtained on the monitor 9 via the image processing circuit 4.

    Thereby, on the monitor 9, a two-dimensional photograph image PIC (camera image viewed from the camera line of sight Z) in a state in which only the portion surrounded by the halo 61 via the image processing circuit 4 is brightly irradiated by the spotlight LT1. Is displayed, and the player proceeds with the game by searching for an item while viewing the two-dimensional photographic image PIC (camera image viewed from the camera line of sight Z).

    At this time, the shape and size of the two-dimensional halo 61 set in the two-dimensional photographic image PIC are calculated based on the three-dimensional model 3DM of the subject captured in the two-dimensional photographic image PIC. Since the image is projected in the direction of the camera line of sight Z in the virtual space 31, the shape of the halo 61 is not a simple shape generated when the spotlight LT1 is irradiated onto the plate-shaped polygon 60, but a two-dimensional photograph. It can be formed corresponding to the original three-dimensional shape of the subject captured in the image PIC. As a result, the player can recognize the halo 61 on the two-dimensional photographic image PIC as if the spotlight LT1 irradiated by the spotlight irradiation device 32 is irradiated on the three-dimensional object. .

    As a result, even when a live-action image is used as the two-dimensional photographic image PIC, it is possible to give the player the feeling of playing a game in a three-dimensional space.

    The present invention can be used as an electronic game device using a computer and entertainment software to be executed by the computer.
