In the case of generating a so-called three-dimensional game image, the drawing unit 120 of the present embodiment firstly stores vertex data (vertex position coordinates, texture coordinates, color data, normal vector, or α value) of each vertex of the object (model). Etc.) is input, and vertex processing is performed based on the vertex data included in the input object data. When performing the vertex processing, vertex generation processing (tessellation, curved surface division, polygon division) for re-dividing the polygon may be performed as necessary.

  In the vertex processing, geometric processing such as vertex movement processing, coordinate transformation (world coordinate transformation, camera coordinate transformation), clipping processing, perspective transformation, or light source processing is performed. The given vertex data is changed (updated or adjusted) for the vertex group to be configured. Then, rasterization (scan conversion) is performed based on the vertex data after the vertex processing, and the surface of the polygon (primitive) is associated with the pixel. Subsequent to rasterization, pixel processing (fragment processing) for drawing pixels constituting an image (fragments constituting a display screen) is performed.

  In pixel processing, various processes such as texture reading (texture mapping), color data setting / changing, translucent composition, anti-aliasing, etc. are performed to determine the final drawing color of the pixels that make up the image, and perspective transformation is performed. The drawing color of the object is output (drawn) to the frame buffer 174 (buffer that can store image information in units of pixels; VRAM, rendering target). That is, in pixel processing, per-pixel processing for setting or changing image information (color, normal, luminance, α value, etc.) in units of pixels is performed.

  Thereby, an image that can be seen from the virtual camera (given viewpoint) set in the object space is generated. Note that when there are a plurality of virtual cameras (viewpoints), an image can be generated so that an image seen from each virtual camera can be displayed as a divided image on one screen.

  Note that the vertex processing and pixel processing performed by the drawing unit 120 are performed by hardware that enables the polygon (primitive) drawing processing to be programmed by a shader program written in a shading language, so-called programmable shaders (vertex shaders and pixel shaders). It may be realized. Programmable shaders can be programmed with vertex-level processing and pixel-level processing, so that the degree of freedom of rendering processing is high, and the expressive power can be greatly improved compared to fixed rendering processing by hardware. .

  The drawing unit 120 performs geometry processing, texture mapping, hidden surface removal processing, α blending, and the like when drawing an object.

  In the geometry processing, processing such as coordinate conversion, clipping processing, perspective projection conversion, or light source calculation is performed on the object. Then, object data (positional coordinates of object vertices, texture coordinates, color data (luminance data), normal vector, α value, etc.) after geometry processing (after perspective projection conversion) is stored in the storage unit 170.

  In texture mapping, a process of mapping a texture (texel value) stored in the texture storage unit 174 of the storage unit 170 to an object is performed. Specifically, the texture (surface properties such as color (RGB) and α value) is read from the texture storage unit 174 of the storage unit 170 using the texture coordinates set (applied) to the vertex of the object. Map an image texture to an object. In this case, processing for associating pixels with texels, bilinear interpolation or the like is performed as texel interpolation.

  In the hidden surface removal processing, hidden surface removal processing is performed by a Z buffer method (depth comparison method, Z test) using a Z buffer (depth buffer) in which the Z value (depth information) of the drawing pixel is stored. That is, when drawing the drawing pixel corresponding to the primitive of the object, the Z value stored in the Z buffer is referred to, and the Z value of the referenced Z buffer and the Z value at the drawing pixel of the primitive are obtained. In comparison, if the Z value at the drawing pixel is a Z value (for example, a small Z value) that is on the near side when viewed from the virtual camera, the drawing pixel is drawn and the Z value in the Z buffer is updated. Update to the correct Z value.

  In α blending (α synthesis), the rendering unit 120 performs translucent synthesis processing (normal α blending, addition α blending, subtraction α blending, or the like) based on an α value (A value). The α value is information that can be stored in association with each pixel (texel, dot), for example, plus alpha information other than color information. The α value can be used as mask information, translucency (equivalent to transparency and opacity), bump information, and the like.

  The parameter update unit 122 updates the durability parameter set for the operation target object according to the position and orientation of the operation target object. Specifically, the parameter update unit 122 refers to the subtraction amount table 178 as shown in FIG. 5A and subtracts the durability parameter from the initial value 100 to 0. In the example of FIG. 5A, as shown in FIG. 5B, the angle γ formed by the normal direction of the rake face PS (the direction of the rake face PS) and the movement direction of the poi object PO in the underwater area WA. Is subtracted so that the amount of subtraction of the durability parameter is larger as the angle is closer to 0 °, that is, when the rake face PS is considered to receive a greater resistance to water. That is, in the underwater area WA, when the poi object PO is moved along the normal direction of the rake face PS, the durability parameter is subtracted so that the value immediately becomes 0, while the poi object PO is moved in the moving direction. As the angle formed by the normal direction of the surface PS increases, the durability parameter is subtracted so that the value does not easily become zero immediately.

  The parameter updating unit 122 may update the durability parameter according to a change in at least one of the position and orientation of the operation target object. For example, the durability parameter is updated at a timing when the change amount (movement amount) and the change amount of the direction of the operation target object exceed a predetermined value.

  The parameter update unit 122 also updates the durability parameter according to the positional relationship between the operation target and each region set in the object space. For example, the durability parameter may be updated when the operation target object moves from one region to another region. Specifically, in the present embodiment, the durability parameter may be updated when the operation target object in the aerial area AA comes into contact with the underwater area WA, or the operation target object in the underwater area WA is updated. The durability parameter may be updated when the aerial area AA is touched. That is, the durability parameter is updated when the operation target object enters or exits.

  The parameter updating unit 122 updates the durability parameter for each region of the operation target object according to the positional relationship between each region of the operation target object and each region of the object space. For example, as shown in FIG. 6, when three areas of the left area LA, the middle area CA, and the right area RA are set on the rake face PS of the poi object PO, only the left area LA contacts the underwater area WA. Then, the durability parameter is updated only for the left region LA.

  The parameter updating unit 122 may update the durability parameter according to the moving speed of the operation target object. In this case, based on the detection information of the detection unit 162, the movement speed information is obtained as the movement information of the operation unit 160 from the movement amount of the operation unit 160 in a predetermined period, and the movement speed information is used as the movement speed of the operation target object. Can be used. The subtraction amount of the durability parameter is increased as the moving speed is faster.

  The parameter updating unit 122 may update the durability parameter according to the elapsed time. For example, a certain amount of durability parameter may be subtracted in accordance with the elapsed time from when the operation target object comes into contact with the underwater area WA (from entering water) until it no longer comes into contact with the underwater area WA (until water discharge).

  The parameter updating unit 122 may update the durability parameter according to the relationship between the direction of the water flow set in the underwater area WA and the direction of the operation target object. In this case, as the angle between the normal direction of the rake face PS in the underwater area WA (the direction of the rake face PS) and the direction of the water flow set in the underwater area WA is closer to 0 °, the durability parameter Subtraction is performed so that the subtraction amount increases. The durability parameter may be updated in consideration of the moving direction of the poi object PO in the underwater area WA. For example, when the moving direction and the direction of the water flow are the same direction, the subtraction amount of the durability parameter may be decreased.

  In addition, the parameter updating unit 122 determines whether the operation target object (for example, the goldfish object KO) and the operation target object (for example, the poy object PO) have a predetermined positional relationship according to the attribute parameter set for the operation target object. Update the degree parameter. For example, when the goldfish object KO is captured by the poi object PO, the durability parameter is updated according to the weight parameter, the rampage parameter, or the like set for the goldfish object KO. The parameter updating unit 122 may update the durability parameter according to the elapsed time when the goldfish object KO is captured by the poi object PO, for example. If the operation target object and the operation target object are in a predetermined positional relationship, the durability parameter may be updated in any of the underwater area WA and the aerial area AA.

  The parameter updating unit 122 updates the durability parameter from the first value to the second value according to the position and orientation of the operation target when the operation target object is located in the first region. When the target object is located in the second region, the durability parameter may be updated from the second value toward the first value based on the motion information. For example, when the poi object PO is located in the underwater area WA, the durability parameter is subtracted according to the movement of the poi object PO. On the other hand, when the poi object PO is located in the aerial area AA, the poi object PO The durability parameter may be added so that the poi object PO is dried and the durability is recovered in accordance with the movement of. Thus, for example, when the poi object PO is located in the underwater area WA, a careful operation is performed so that the rake face PS of the poi object PO is not broken (a parameter is not subtracted), and the poi object PO When the position is in the aerial area AA, a violent operation may be performed so that the rake face PS of the poi object PO is dried (a parameter is added).

  When the durability parameter is updated in this way, the above-described display control unit 113 changes the color of the rake face PS of the poi object PO in accordance with the update of the durability parameter. For example, the color and transparency of the rake face PS may become lighter as the durability parameter decreases.

  The event generation unit 124 generates a given event according to the value of the durability parameter. Specifically, in the present embodiment, the event generation unit 124 generates an event in which the rake face PS of the poi object PO is broken when the durability parameter is updated to zero. That is, the display control unit 113 performs a display control process in which the rake face PS of the poi object PO is broken, and prevents the goldfish object KO from being scooped by the poi object PO. Here, as shown in FIG. 6, when a plurality of areas are set on the rake face PS, a process for generating an event for each area is performed. Then, when the durability parameter becomes 0 for all the rake faces PS, processing for ending the game is performed.

  The evaluation unit 126 performs evaluation related to the operation of the operation unit 160. In particular, if the goldfish object KO, which is the operation target, is moved so as to follow the movement of the poi object PO, which is the operation target, and is placed in the bowl object OO, the game condition is evaluated. Specifically, in the present embodiment, the number of reserved goldfish objects KO is displayed as a score display PG, or “delicious!” Or the like is displayed to perform processing for evaluating the operation of the operator.

  The sound generation unit 130 performs sound processing based on the results of various processes performed by the processing unit 100, generates game sounds such as BGM, sound effects, or sounds, and outputs the game sounds to the sound output unit 192.

  Note that the image generation system of the present embodiment may be a system dedicated to the single player mode in which only one player can play, or may be a system having a multiplayer mode in which a plurality of players can play.

  In addition, when a plurality of players play, game images and game sounds provided to the plurality of players may be generated using one terminal, or connected via a network (transmission line, communication line), etc. It may be generated by distributed processing using a plurality of terminals (game machine, mobile phone).

4). Details of Processing Next, details of an example of processing according to the present embodiment will be described with reference to a flowchart.

4-1. Parameter Update Process FIG. 7 is a flowchart showing details of an example of the durability parameter update process of the present embodiment. As shown in FIG. 7, first, when motion information is input by moving the controller 16 by the player (Y in step S10), the position and orientation of the poi object PO are controlled based on the motion information (step S12). ).

  FIGS. 8A and 8B are conceptual diagrams for explaining the movement of the poi object PO in accordance with the movement of the controller 16, and the real space RS in which the controller 16 moves and the object in which the poi object PO moves. The space OS is seen from the side. As shown in FIG. 8A, in this embodiment, when the player brings the controller 16 close to the display screen 11 of the display unit 12, the poi object PO in the aerial area AA is changed to the underwater area WA according to the movement amount of the controller 16. Move towards That is, the poi object PO moves in the Z axis depth direction in the object space OS. On the other hand, when the controller 16 is moved away from the display screen 11 of the display unit 12, the poi object PO moves toward the aerial area AA according to the movement amount of the controller 16. That is, the poi object PO moves in the front direction of the Z axis in the object space OS. That is, the poi object PO is moved based on the distance information of the controller 16 with respect to the display screen 11.

  Further, as shown in FIG. 8B, when the player moves the controller 16 in the vertical direction with respect to the display screen 11 of the display unit 12, the poi object PO moves in the vertical direction on the Y axis according to the movement amount of the controller 16. Moving. Further, when the player moves the controller 16 in the left-right direction (the front-rear direction in the figure) with respect to the display screen 11 of the display unit 12, the poi object PO moves in the left-right direction of the X-axis (see FIG. Move inward (backward direction). That is, the poi object PO is moved based on the indicated position information of the controller 16 on the display screen 11. In the present embodiment, the poi object PO can be moved vertically and horizontally in both the aerial area AA and the underwater area WA.

  Further, in the present embodiment, as shown in FIG. 9B, the controller 16 does not move in parallel with the display screen 11 as shown in FIG. May be moved in the X-axis and Y-axis directions in accordance with the amount of change in the direction of the controller 16. That is, the poi object PO may be moved according to the position indicated by the controller 16 on the display screen 11.

  As shown in FIG. 9B, the direction of the poi object PO is changed in accordance with the amount of change in the direction of the controller 16 by moving the indicated direction (the direction of the controller 16) of the controller 16 up, down, left and right. Also good. For example, by moving the pointing direction of the controller 16 (the direction of the controller 16) up and down, the rotation angle of the poi object PO around the X axis is changed, and by changing the pointing direction of the controller 16 (the direction of the controller 16). The rotation angle around the Z axis of the poi object PO may be changed.

  In this embodiment, as shown in FIG. 10, the rotation angle of the poi object PO around the Y axis changes according to the amount of change in the rotation angle of the controller 16 by rotating the controller 16 around the axis along the indicated direction. Let

  In this embodiment, the position and orientation of the poi object PO are controlled in accordance with such a combination of the position, orientation, rotation angle, instruction position, and the like of the controller 16 itself. Therefore, depending on the movement of the controller 16 itself, the normal direction of the rake face PS of the poi object PO (the direction of the rake face PS), the movement direction, the movement amount, the movement speed, etc. of the poi object PO are set in various states. Can be changed. The sensor that acquires the position, orientation, rotation angle, designated position, and the like of the controller 16 itself may be a CMOS sensor (first detection unit) or an acceleration sensor (second detection unit). Moreover, it is good also as those arbitrary combinations.

  When the position and orientation of the poi object PO are controlled in this way (step S12 in FIG. 7), if the position where the poi object PO exists is underwater (Y in step S14), the durability parameter associated with the movement of the poi object PO. Update. In the present embodiment, the durability depends on the angle formed by the normal direction of the rake face PS (the direction of the rake face PS) of the poi object PO and the movement direction of the poi object PO when the poi object PO is moved. Process to subtract parameters. On the other hand, when the position where the poi object PO exists is not underwater (N of step S14), the process of step S10-step S14 is repeated without updating the durability parameter accompanying a movement.

  If the durability parameter becomes 0 due to the update of the durability parameter accompanying the movement (Y in step S18), an event that breaks the rake face PS is generated (step S26), and the game ends. On the other hand, if the durability parameter does not become 0 (N in step S18), it is determined whether the goldfish object KO and the rake face PS are in contact. If they are in contact (Y in step S20), the contact is determined. A process of subtracting the durability parameter of the poi object PO according to the attribute parameter set for the goldfish object KO is performed (step S22). On the other hand, when it is not in contact with the goldfish object KO (N in step S20), the processes in steps S10 to S20 are repeated without updating the durability parameter associated with the contact.

  If the durability parameter becomes 0 due to the update of the durability parameter associated with the contact (Y in step S24), an event that breaks the rake face PS is generated (step S26), and the game ends. On the other hand, if the durability parameter does not become 0 (N in step S24), the process returns to step S10 and the above process is repeated until the game end condition is satisfied.

4-2. Rake Process FIG. 11 is a flowchart showing details of an example of a scoop process when scooping a goldfish object KO with the poi object PO of this embodiment. As shown in FIG. 11, first, it is determined whether the upper surface of the rake face PS of the poi object PO is in contact with the goldfish object KO, that is, whether the goldfish object KO is placed on the rake face PS (step S40). . If contact is made (Y in step S40) and movement information is input by the player moving the controller 16 (Y in step S42), it is determined whether the durability parameter is 0 or not. (Step S44).

  If the durability parameter is not 0 (N in step S44), it is determined whether or not the center point CP of the goldfish object KO that is in contact is within the rake face PS (step S46). Here, as shown in FIG. 12A, when the center point CP of the goldfish object KO that is in contact is within the rake face PS (Y in step S46), the rake face PS at that time is relative to the water surface. It is determined whether or not the angle is 41 ° or less (close to horizontal), that is, whether the angle is within a range where the goldfish object KO is scooped (step S48). Here, as shown in FIG. 12 (A), when the angle of the rake face PS with respect to the water surface is 41 ° or less (close to the horizontal) (Y in step S48), according to the motion information of the controller 16, the poi The goldfish object KO is moved so as to follow the movement of the object PO (step S50). That is, the poi object PO and the goldfish object KO that were in the underwater area WA as shown in FIG. 12 (A) are moved to the aerial area AA as shown in FIG. 12 (B), and the goldfish object KO is scooped up by the poi object PO. To be able to.

  On the other hand, even if motion information is input (Y in step S42), if the durability parameter is 0 (Y in step S44), or as shown in FIG. When the center point CP is not in the rake face PS (N in step S46), or as shown in FIG. 13B, the angle of the rake face PS with respect to the water surface is not less than 41 ° (away from the horizontal) (step) In N of S48, a process for the goldfish object KO to escape from the poi object PO is performed (step S52).

  In step S50, as a result of moving the poi object PO and the goldfish object KO, the poi object PO and the goldfish object KO are predetermined aerial areas AA in the vicinity of the bowl object OO as shown in FIG. It is determined whether or not it has moved to a position (step S54). If it has moved to a predetermined position (Y in step S54), it is determined whether or not the angle of the rake face PS with respect to the water surface is 41 ° or more (away from the horizontal), that is, the goldfish object KO is moved to the bowl object OO. It is determined whether the angle has been operated within a range that can be lowered (step S56). Here, when the angle is operated to be 41 ° or more (away from the horizontal) (Y in step S56), the goldfish object KO that has been following the poi object PO is changed to the bowl object as shown in FIG. This is dropped into the OO and secured (step S58).

  Then, a process for evaluating the operation of the operator is performed by displaying the number of secured goldfish objects KO on the display screen 11 as a score display PG or displaying “Delicious!”. In this embodiment, the above-described processes are repeated until the rake face PS of the poi object PO is broken, that is, until the durability parameter becomes 0, and a goldfish rake game can be enjoyed. Even when the poi object PO is located in the aerial area AA, when the goldfish object KO is placed on the poi object PO, the durability parameter may be updated.

  As described above, in this embodiment, the angle formed by the direction (normal direction) of the rake face PS of the poi object PO and the movement direction of the poi object PO is closer to the right angle, that is, the direction of the rake face PS with respect to the movement direction. As the (normal direction) lies, the durability parameter is less likely to be updated (advantageous to the player). However, when scooping up and picking up the goldfish object KO, if the angle formed by the direction of the rake face PS (normal direction) and the direction of the water surface (reference plane) (normal direction) approaches a right angle, the goldfish object KO Run away (disadvantageous to the player). Therefore, the player puts the durability parameter on the rake face PS as much as possible in consideration of the relationship between the direction (normal direction) of the rake face PS, the movement direction of the poi object PO, and the water surface. By appropriately operating the position and orientation of the controller 16 so that the goldfish object KO does not escape, the poy object PO is moved appropriately, until the durability parameter becomes 0 and the rake face PS is broken as much as possible. Enjoy the game of winning goldfish objects.

  According to the present embodiment, the durability parameter that reflects the movement of the controller 16 in more detail can be updated. For example, even if the distance by which the poi object PO is moved in the underwater area WA is the same, if the direction of the rake face PS at that time is different, the manner of updating the durability parameter can be made different. As described above, according to the present embodiment, the movement of the controller 16 (player operation details) can be reflected in the display of the POI object PO and the durability parameter update (operation result) in a more realistic manner. The virtual reality of the player can be effectively enhanced.
