  Conventionally, in a sound system in the video game field (a system for outputting sound in accordance with the progress of a game), when there is an acoustic shielding object (shielding object) in the virtual space, the shielding object against the sound generated in the virtual space. In consideration of the influence of the above, a process (acoustic process) for determining a sound (listening sound) heard at the listening position (for example, the position of the player character) is executed.

  Hereinafter, examples of embodiments of the present invention will be described with reference to the drawings. Various constituent elements in the embodiments described below can be appropriately combined within a range in which no contradiction occurs. Moreover, the content described as an example of a certain embodiment may be omitted in other embodiments. The contents of operations and processes not related to the characteristic part of each embodiment may be omitted. Furthermore, the order of the various processes constituting the various flows described below is in no particular order as long as no contradiction occurs in the processing contents.

[First Embodiment]
FIG. 1 is a block diagram showing an example of the configuration of a video game processing apparatus 10A (apparatus 10A) according to an embodiment of the present invention. The device 10A has various functions for displaying at least a part of a virtual space in which a sound source, a listening position, and a shield are arranged on the display screen of the display device to control the progress of the video game.

  In this example, the device 10A is managed by a user (player) who plays a video game, and can carry a network-distributed game such as a mobile phone terminal, a PDA (Personal Digital Assistants), or a portable game device. Consists of communication terminals. Note that the information related to the video game may be read from a storage medium or may be received from an external device.

  As illustrated in FIG. 1, the device 10 </ b> A includes at least a detour point setting unit 11, a change unit 12, a determination unit 13, a derivation unit 14, and a generation unit 15.

  The detour point setting unit 11 has a function of setting a detour point of sound generated from the sound source on the shield.

  Here, the shield means an object that blocks transmission of sound in the virtual space. Although the configuration of the shield is not particularly limited, in the present example, description will be given by taking a shield defined by coordinates in the virtual space as an example. That is, the shield in this example is configured by coordinates (or points) and lines that can be specified by the coordinates.

  The sound source means a sound generating sound in the virtual space. The sound source in this example is a concept including a position in the virtual space. The sound source management method is not particularly limited. For example, the sound source management object, sound generation conditions, sound information, and a position in the virtual space are associated with each other and stored in a predetermined storage area. Also good.

  The detour point means a point where the sound detours. That is, in this example, the information for specifying the sound propagation path includes a detour point. As a method for specifying a propagation path in the virtual space, it is preferable to adopt a method in which a propagation path similar to the propagation path in the same real space is specified in consideration of the balance with the processing load. In other words, a path in which the sound bypasses the shield may be specified as the sound propagation path, or another element may be reflected. Examples of other elements include sound level and shielding material.

  The changing unit 12 has a function of changing the detour point to a position (the rising position) where the detour point has floated from the shield.

  Here, levitation means coming out on the surface. The position floating from the shield defined by the point and the line means a position obtained by changing (or moving) a coordinate coincident with the point or the line by a certain distance. In this example, the changing unit 12 changes the position of the detour point set on the shield to the floating position according to a predetermined rule (that is, raises the detour point). The content of the predetermined rule is not particularly limited as long as the floating position is on the sound source side, but it is preferable that the content is simple so that the processing load required for defining the floating position is not excessive.

  The determination unit 13 has a function of determining whether or not sound directly reaches the listening position from the ascent position.

  Here, the criterion for determining whether or not the sound reaches directly is not particularly limited, but is preferably a criterion that takes into account the nature of the sound in the real space and the processing load required for the determination. In this example, the determination unit 13 determines that sound directly reaches the listening position from the floating position when the shielding body is not positioned immediately before connecting the floating position and the listening position.

  The deriving unit 14 has a function of deriving a sound propagation path using the flying position when it is determined that the sound reaches directly.

  Here, deriving the propagation path using the ascending position means deriving a propagation path having the ascending position as the detour point of the sound. That is, the propagation path in this example means a path that passes from the sound source through the detour point and reaches the listening position. Note that a method for deriving a propagation path in a state where a sound source, a detour point, and a listening position are defined is not particularly limited, and it is not always necessary to pass through all detour points. As an example of the propagation route derivation method, there is a known shortest route derivation method using a detour point as a passage candidate.

  The generation unit 15 has a function of generating output information related to the sound generated by the sound source based on the propagation path.

  Here, the configuration for generating the output information is not particularly limited, but it is preferable that the configuration is such that reality is recognized as the sound that is heard at the listening position. As an example of a configuration for producing output information, there is a configuration in which output information is generated using the direction of the propagation path with respect to the listening position, the length of the propagation path itself, the number of propagation paths, and the output setting in the apparatus 10A. .

  Next, the concept of deriving the propagation path using the flying position will be described.

  2 to 7 are explanatory diagrams for explaining examples of sound propagation paths. Here, a description will be given by taking as an example a virtual space in which the sound source 20, the listening position 30, and the shield 40 are arranged. In the situation shown in FIG. 2, at least one of the propagation paths of the sound generated by the sound source 20 is considered to be the path 50. However, in the conventional technique, a so-called thickness zero problem occurs, and it is difficult to derive the path 50. Hereinafter, the thickness 0 problem and a solution to the thickness 0 problem will be described.

  As shown in FIG. 3, when deriving a sound propagation path, first, an intersection 61 between a straight line 60 connecting the sound source 20 and the listening position and the shield 40 is obtained. Here, when there are a plurality of intersections, the one close to the sound source is selected, and the shield 40 is scanned left and right from that point. That is, it can be heard directly along the line or scanned sequentially. Hereinafter, a case where scanning is performed in the clockwise direction on the paper surface (arrow 62 in FIG. 3) will be described as an example.

  As shown in FIG. 4, it is determined whether or not the sound reaches the listening position directly for the corner 71 located in the direction of the arrow 62 from the intersection 61. In this case, it is usually determined that “the sound reaches directly”. This is because what constitutes the shield 40 is a line segment, and a point on the line segment has neither the other side nor the other side. Therefore, when scanning to the end, as shown in FIG. 4, it is determined that all sounds except for the end portion 74 are “sound reaches directly”, and the path 50 cannot be derived. This is the “thickness 0 problem” in this example. Hereinafter, a method for solving the thickness 0 problem will be described.

  In order to solve the zero thickness problem and to be able to derive the path 50, the “floating position” is used. Here, it can be said that the floating position is a position where the corner or end of the shield is shifted.

  As shown in FIG. 5, the position is levitated from the corner 71. As for the method for specifying the flying position, it is preferable that the flying direction is an appropriate direction and the flying height is not excessive. An example of a configuration for specifying the ascent position is a configuration in which the front-rear direction is obtained by the inner product of the surface normal of the shield and a vector from the listening position toward the shield, and the surface is levitated at a predetermined value (that is, a line segment collision) There is a configuration in which the flying position according to the scanning condition is defined in advance at the corner and the end. In addition, the structure for specifying a floating position is not limited to these, For example, it is good also as a structure which uses a some structure separately according to the characteristic of a shield, a sound source, and a listening position.

  As shown in FIG. 6, when the shield 40 is scanned in the clockwise direction on the paper surface, it is determined that “the sound can reach directly” by setting the floating position at the corner and the end. Only the corner 73 after passing through is provided, and a plurality of vectors 80 to 86 can be specified.

  As shown in FIG. 7, after specifying a plurality of vectors 80 to 86, two paths 91 and 92 can be derived by searching for a location that can be shortcutted as a path from the sound source 20 to the listening position 30. Therefore, the route 50 shown in FIG. 2 can be finally derived. The shortcut route search may be performed at any time instead of the last. Alternatively, the sound propagation path may be specified by combining or selecting the counterclockwise and clockwise results.

  Next, the operation of the apparatus 10A of this example will be described.

  FIG. 8 is a flowchart illustrating an example of game processing executed by the device 10A. The game processing in this example is directly or indirectly related to controlling the progress of the video game by displaying at least a part of the virtual space in which the sound source, the listening position, and the shield are arranged on the display screen of the display device. Processing is performed.

  The game process is started when sound is generated from a sound source arranged in the virtual space according to the progress of the video game, for example.

  In the game process, the device 10A first sets a sound detour point on the shield (step S11). In this example, the apparatus 10A sets a detour point in the shield disposed between the sound source and the listening position.

  When the detour point is set, the device 10A changes the set detour point to the floating position (step S12). In this example, the device 10A specifies the ascent position so that the detour point is shifted to the position on the sound source side, and changes the detour point to the specified ascent position.

  When the detour point is changed to the floating position, the device 10A determines whether or not sound directly reaches the listening position from the changed position (step S13). In this example, the device 10A determines that the sound reaches directly when there is no shield on the straight line connecting the detour point after change and the listening position. Here, for example, when it is determined that the sound does not reach directly due to the presence of a shield between the detour point and the listening position (N in Step S13), the apparatus 10A proceeds to the process of Step S11 and moves to the next detour point. Set.

  On the other hand, if it is determined that the sound reaches directly (Y in step S13), the device 10A derives a propagation path (step S14). In this example, the device 10A derives a path that passes through the detour point set so far as a path (propagation path) through which the sound generated from the sound source propagates to the listening position.

  When deriving the propagation path, apparatus 10A generates output information based on the derived propagation path (step S15), and ends the processing here. In this example, the device 10A generates output information based on information related to sound output (for example, the length of the propagation path), and outputs sound based on the generated output information.

  As described above, as one aspect of the first embodiment, the progress of the video game is controlled by displaying at least a part of the virtual space in which the sound source, the listening position, and the shield are arranged on the display screen of the display device. The video game processing apparatus 10A includes a detour point setting unit 11, a change unit 12, a determination unit 13, a derivation unit 14, and a generation unit 15, and provides a detour point of sound generated from the sound source on the shield. Set and change the detour point to the position where it floated from the shield (floating position), determine whether the sound reaches the listening position directly from the floating position, and if it is determined that the sound reaches directly, It can be used to derive a sound propagation path, generate output information related to the sound generated by the sound source based on the propagation path, and efficiently derive a sound propagation path that bypasses the shield.

  In other words, by using the floating position, for example, the amount of data and processing load can be reduced compared to a method of defining a region that can be a detour point setting position around a shield defined by points and lines. it can. Further, by generating output information that can output sound through a speaker or the like, it is possible to output sound according to the progress of the video game.

  Although not particularly mentioned in the above-described example of the first embodiment, the device 10A may generate output information for displaying the derived propagation path on the display screen of the display device. Note that the use of the floating position is also useful when adding sound to video used in video games.

[Second Embodiment]
FIG. 9 is a block diagram showing an example of the configuration of the video game processing device 10B (device 10B) according to the embodiment of the present invention. In this example, the device 10B includes at least a detour point setting unit 11B, a change unit 12B, a determination unit 13, a derivation unit 14, and a generation unit 15.

  The detour point setting unit 11B has a function of setting the intersection of the line connecting the sound source and the listening position and the shield as the first detour point.

  Here, the first detour point means a detour point that is set first at the stage of setting the detour point. That is, the propagation path derived last does not necessarily have to pass through the first detour point.

  When the detour point cannot determine whether the detour point is on the side of the sound source or the listening position with respect to the shield, the changing unit 12B can be defined according to a predetermined rule or a position previously associated with the position of the detour point Has a function of setting the levitation position to.

  Here, the case where determination is not possible means that the detour point is on the shield, that is, the coordinate of the detour point matches the coordinate of the shield.

  An example of the predetermined rule is a rule that uses a normal vector of a line or a surface where a detour point is set. Moreover, it is good also as a structure which uses the rule which sets a different floating position for the part on the shield in which the detour point was once set. That is, for example, with respect to the shield shown in FIG.

  FIG. 10 is a flowchart illustrating an example of game processing executed by the device 10B.

  In the game process, the device 10B first sets a first detour point (step S2-11). In this example, the device 10B uses a different rule for setting the first detour point than for setting the next detour point.

  When the first detour point is set, the device 10B changes the set detour point to the floating position (step S12). In this example, the device 10B changes the detour point to a floating position that has moved a predetermined distance in the normal direction of the shield at the detour point.

  When the detour point is changed to the ascent position, the device 10B determines whether or not sound directly reaches the listening position from the changed detour point (that is, the ascent position) (step S2-12). In this example, the device 10B determines that “the sound reaches directly” when there is no shield on the line connecting the detour point and the listening position.

  If it is determined that the sound does not reach directly (N in Step S2-12), the device 10B sets the next detour point (Step S2-13). In this example, the device 10B searches for a corner or an edge of the shield located in the right direction or the left direction from the detour point, determines whether or not the sound directly reaches, and detours if not. Change the point to the flying position.

  On the other hand, if it is determined that the sound reaches directly (Y in step S2-12), the apparatus 10B derives a propagation path (step S14), generates output information based on the derived propagation path (step S15), and here The process in is terminated.

  As described above, as one aspect of the second embodiment, the video game processing device 10B includes the detour point setting unit 11B, the change unit 12B, the determination unit 13, the derivation unit 14, and the generation unit 15. Since the intersection of the line connecting the sound source and the listening position and the shield is set as the first detour point, it cannot be determined whether the detour point is on the sound source or the listening position side with respect to the shield. In such a case, a propagation path derivation method in which a position definable according to a predetermined rule or a position previously associated with the position of the detour point is a floating position, and the first detour point is not limited to the corner or end of the shield Can be realized.

[Third Embodiment]
FIG. 11 is a block diagram showing an example of the configuration of a video game processing apparatus 10C (apparatus 10C) according to an embodiment of the present invention. In this example, the device 10 </ b> C includes at least a detour point setting unit 11 </ b> C, a change unit 12, a determination unit 13, a derivation unit 14 </ b> C, and a generation unit 15.

The detour point setting unit 11C causes the determination unit 13 to “no sound directly reaches the listening position from the ascent position”
If it is determined, the function of setting the next detour point based on the shape of the shield is provided.

  Here, based on the shape of the shield means that the points and lines constituting the shield are used for setting the next detour point. In this example, the detour point next to the detour point changed to the floating position is also set on the shield.

  The detour point setting unit 11 </ b> C has a function of setting the detour point as the last detour point when the determination unit 13 determines that “the sound reaches directly from the ascending position to the listening position”.

  Here, the last detour point is a detour point where there is no shield between the listening position and a detour point where the next detour point is not set.

  The deriving unit 14C has a function of deriving, as a propagation path, a path that reaches at least the listening position from the sound source through the last detour point. That is, the method for deriving the propagation path by the deriving unit 14C is not limited to the method using all the set detour points. An example of a method for deriving the propagation path is when there is no shield on the line connecting the sound source and the last detour point, and the line connecting the sound source and the last detour point and the line connecting the last detour point and the listening position It is good also as a structure by which the path | route comprised is derived | led-out as a propagation path.

  FIG. 12 is a flowchart illustrating an example of game processing executed by the device 10C.

  When the detour point is changed to the floating position (step S12), the device 10C determines whether or not sound directly reaches the listening position from the detour point after the change (step S3-11).

  If it is determined that the sound does not reach directly (N in Step S3-11), the device 10C sets the next detour point (Step S3-12), and proceeds to the process in Step S12.

  On the other hand, if it is determined that the sound reaches directly (Y in step S3-11), the device 10C sets the last detour point (step S3-13), and derives a propagation path that passes through the last detour point (step S3-13). Step S3-14), the processing here ends.

  As described above, as one aspect of the third embodiment, the video game processing device 10C includes the detour point setting unit 11C, the change unit 12, the determination unit 13, the derivation unit 14C, and the generation unit 15. If the sound does not reach directly, the next detour point is set based on the shape of the shield, and if the sound reaches directly, the last detour point is set, and at least the last detour point from the sound source A path that passes through the path and reaches the listening position can be derived as a propagation path, and a path that detours along the shield can be derived as a sound propagation path.

  Although not specifically mentioned in the above-described third embodiment, the device 10C stores the sequentially set detour points in a predetermined storage area, sets the last detour point, and then stores the detour points. Further, a configuration may be adopted in which the propagation path of the sound generated by the sound source is derived with reference to the sound source and the listening position.

[Fourth Embodiment]
FIG. 13 is a block diagram showing an example of the configuration of the video game processing device 10D (device 10D) according to the embodiment of the present invention. In this example, the device 10D includes at least a detour point setting unit 11D, a change unit 12D, a determination unit 13, a derivation unit 14D, and a generation unit 15.

  The detour point setting unit 11D has a function of setting any one of at least one corner or end constituting the shield as a detour point. In addition, the structure for specifying a corner | angular part or an edge part will not be specifically limited if the propagation path finally derived | led-out does not penetrate a shield.

  The changing unit 12D has a function of changing the detour point to a position that has floated by a predetermined distance in the direction set at the corner and end of the shield. In this example, it is assumed that vectors indicating directions and distances are set at the corners and ends of the shield. Note that the predetermined information (default information) is not limited to a vector for each corner or end, and may be information that allows the detour point to be lifted by a very small value in a direction not penetrating the shield.

  The deriving unit 14D has a function of deriving a path composed of one or more line segments connecting the sound source to the listening position as a propagation path. In this example, the derivation unit 14D sets a position where the line segment cannot cross on the shield, a position where the detour point can be set as an end point of the line segment, and a path having the shortest length as at least one propagation path It has a function to derive. That is, the propagation path in this example is derived as a broken line that does not cross the shield.

  FIG. 14 is a flowchart illustrating an example of game processing executed by the device 10D.

  In the game process, the device 10D first sets a detour point at the corner or end of the shield (step S4-11). In this example, the device 10D identifies a shield disposed between the sound source and the listening position, and identifies the configuration of the identified shield (for example, a normal vector of lines and corners) and a vector from the sound source toward the shield. A detour point is set based on and.

  When the detour point is set, the device 10D changes the detour point to the flying position according to the default information (step S4-12). In this example, the device 10D refers to the default information corresponding to the corner or end where the detour point is set, identifies the ascent position, and changes the detour point to the identified ascent position.

  When the detour point is changed to the floating position, the device 10D determines whether or not sound reaches the listening position from the changed detour point (step S13). When it is determined that the sound reaches, the shortest path that satisfies a predetermined condition Is derived. In this example, the device 10D derives the shortest route among the routes that pass through the detour point that is determined to receive sound at least among the set detour points.

  When deriving the shortest path, apparatus 10D derives and generates output information based on the shortest path (step S14), and ends the processing here.

  As described above, as one aspect of the fourth embodiment, the video game processing device 10D includes the detour point setting unit 11D, the change unit 12D, the determination unit 13, the derivation unit 14D, and the generation unit 15. Therefore, any one of at least one corner or end constituting the shield can be set as a detour point, and a sound propagation path that does not penetrate the shield can be derived.

  Further, in the example of the fourth embodiment described above, the video game processing device 10D is configured to change the detour point to a position that has risen by a predetermined distance in the direction set at the corner and the end. A detour route can be derived with a configuration that requires limited data.

  Further, in the example of the fourth embodiment described above, when the video game processing device 10D derives, as a propagation path, a path composed of one or a plurality of line segments connecting the sound source to the listening position, on the shield. Is defined as a position where the line segment cannot be crossed and the detour point can be set as the end point of the line segment, and the path with the shortest length is derived as at least one propagation path. A useful route can be selected also when a plurality of detour routes are derived according to the above.

  As described above, one or more deficiencies are solved by each embodiment of the present application. In addition, the effect by each embodiment is an example of a non-limiting effect or effect.

  Although not specifically mentioned in each of the above-described embodiments, the video game processing device includes a storage unit that stores sound source arrangement information, shield information, and normal information related to the shield in association with each other, A configuration may be adopted in which a sound propagation path from the sound source (that is, a detour path that bypasses the shield) is derived in response to the reception of the listening position. In this case, examples of the sound source arrangement information include an audible range and position information. An example of the shield information is a polygon shape. Furthermore, as an example of normal line information, there is one in which the normal line of each polygon constituting the shield is obtained in advance.

  Although not particularly mentioned in the above-described embodiment, the structure for deriving the sound propagation path using the floating position has no change in the designer work related to the video game, and therefore increases the designer work load. There is no. Further, complicated processing is not performed as route search, and it is light for CPU calculation, and an increase in data memory required for calculation can be suppressed to a minimum.
