Embodiment 1
Specific examples of the display method and the program according to the first embodiment of the present invention will be described below with reference to the drawings. The present invention is not limited to these exemplifications, but is defined by the scope of claims for patent, and it is intended that all modifications within the meaning and scope equivalent to the scope of claims for patent are included in the present invention. In the following description, the same reference numerals are given to the same elements in the description of the drawings, and repeated description is not repeated.

  FIG. 1 is a block diagram illustrating a main configuration of the terminal device 1. As illustrated in FIG. 1, the terminal device 1 includes an input device 11, a display 12, and a control unit 13. The terminal device 1 is a device that can execute various applications including a computer game. The terminal device 1 may be, for example, a smartphone, a PDA (Personal Digital Assistant), a tablet computer, a game console, or a general-purpose PC (Personal Computer).

  The input device 11 is a device for a user to input information to the terminal device 1 or perform input for operating the terminal device 1, and is, for example, a touch panel. The display 12 is a device that displays various types of information such as text and images, and is a screen device such as a liquid crystal display. The control unit 13 includes a processor and a memory, and comprehensively controls the operation and processing of the terminal device 1. The control unit 13 generates an image to be displayed on the display 12 based on an application program such as a game program stored in the memory, various game images and object data, and a user operation input received by the input device 11. The control unit 13 includes a terrain object image display unit 21, a moving image texture generation unit 23, and a moving image texture reproduction unit 24. The terrain object image display unit 21 causes the display 12 to display a terrain object image based on the terrain object data. The grid line assignment unit 22 assigns grid lines to the terrain object image. The moving image texture generation unit 23 generates a moving image texture displayed on the grid line. The moving image texture reproduction unit 24 reproduces the moving image texture arranged on the grid line, and displays an animation image corresponding to the moving image texture on the display 12.

  As an application accompanied by display of a terrain object image, for example, a golf game can be cited. Below, the case where the terminal device 1 is a game device which performs a golf game is demonstrated. However, the terminal device 1 is implemented not only as a golf game but also as a device capable of executing any application (either a game or other than a game) that involves displaying a terrain object image.

  FIG. 2 is a diagram illustrating a golf game play screen example displayed on the display 12 of the terminal device 1. For example, the terminal device 1 displays a play screen as shown in FIG. The example of FIG. 2 shows a scene in the preparation stage before the player character image 31 based on the player character data is put on the green of the virtual golf course. The display 12 displays a terrain object image 32 constituting a golf course, and a grid 33 is arranged on the terrain object image 32. When the golf game is executed, the terminal device 1 performs a display effect in which a plurality of patterns are made to move on the grid 33 in a manner corresponding to the inclination defined in the terrain object image 32. The user can grasp the degree of inclination of the terrain object image 32 by visually recognizing the movement of the pattern. In the present embodiment, the movement of the pattern on the grid 33 is realized not by the movement process of the pattern object image but by the reproduction of the moving image texture including the pattern (display of the animation image).

  FIG. 3 is a diagram illustrating the configuration of the grid 33. The grid 33 is composed of a plurality of grid lines 41. As shown in FIG. 3A, a plurality of grid lines 41 arranged in a grid shape are allocated on the terrain object image 32. In the example of FIG. 3, each grid line 41 corresponds to any one of four sides surrounding any section in the grid 33. That is, one section on the terrain object image 32 is formed by the four grid lines 41. As shown in FIG. 3B, the grid line 41 is a single plate polygon obtained by combining two triangular polygons 42 and triangular polygons 43. The plate polygon is a polygon that does not have a thickness but has a two-dimensional extent. Both the triangular polygon 42 and the triangular polygon 43 have a right triangle shape. In the grid line 41, the hypotenuse of the triangular polygon 42 and the hypotenuse of the triangular polygon 43 are in contact with each other.

  The terminal device 1 arranges the moving image texture for expressing the movement of the pattern on the grid 33 on each grid line 41. Furthermore, the terminal device 1 reproduces a moving image texture (grid line texture) arranged on the grid line 41 and displays an animation image corresponding to the moving image texture on the display 12, thereby displaying a screen display as shown in FIG. Realize.

  When the golf game is executed, the terminal device 1 dynamically generates a moving image texture arranged on the terrain object image 32 in a manner corresponding to the inclination of the arrangement position, and then arranges it. FIG. 4 is a diagram illustrating a procedure for generating a moving image texture. The moving image texture generation unit 23 causes the display 12 to display the terrain object image 32 in which the inclination is defined. The grid line assignment unit 22 assigns grid lines 41 to the terrain object image 32. In the example of FIG. 4, the terrain object image 32 defines both the position to which the grid line 41 is assigned in the terrain object image 32 and the inclination angle θ (degree of inclination) of the terrain at the position.

  In the memory of the terminal device 1, a pattern image 61 (first image) and a background image 62 (second image) used for generating a moving image texture are prepared in advance. The pattern image 61 corresponds to a pattern included in the moving image texture, and the background image 62 corresponds to the background included in the moving image texture. The pattern image 61 is an image that can define directions such as front and rear, and is a heart-shaped image in the example of FIG. The background image 62 is an image having no directionality such as forward and backward, and may be an image configured with a color tone such as white (or colorless), or an image configured with a pattern or the like. Thus, the pattern image 61 and the background image 62 are different images. The moving image texture generating unit 23 combines the pattern image 61 and the background image 62 in a manner corresponding to the inclination angle θ of the position to which the grid line 41 is assigned in the terrain object image 32, thereby moving the moving image texture arranged on the grid line 41. 63 is generated.

  First, the moving image texture generation unit 23 divides the grid line 41 into a plurality (three in this embodiment) of equal partial areas (constant areas) and specifies partial areas 51 to 53 obtained by this division. Next, the moving image texture generation unit 23 sets a tilt angle θ and a parameter having a value corresponding to the position at each position in the identified partial areas 51 to 53. FIG. 4 shows an example in which an α value, which is a numerical value representing image transparency, is set in the partial region 52 as a representative.

  The moving image texture generation unit 23 sets “0” as the α value at the position (left end) where the height of the topographic object image 32 in the partial region 52 is the lowest. Further, as the position in the partial region 52 moves from the left end toward the right end, the α value at each position varies in a straight line rising upward at an angle θ corresponding to the inclination angle θ of the terrain object image 32. The α value is set at each position. The moving image texture generation unit 23 sets an α value of “1” at the maximum. In FIG. 4, the α value at the right end of the partial region 52 is approximately 1.

  The moving image texture generation unit 23 defines each position where the α value is equal to or greater than a predetermined threshold (for example, about 0.3 to 0.5) in the partial region 52 as the first range, while the α value is in the partial region 52. Each position that is less than the predetermined threshold is defined as a second range. Then, the length of the pattern image 61 is determined based on the length of the first range (for example, the same), and the length of the background image 62 is determined based on the length of the second range (for example, the same). . Here, the length of the pattern image 61 and the length of the background image 62 are the lengths in the direction in which the grid lines 41 extend. The moving image texture generation unit 23 determines the enlargement ratio (or reduction ratio) in the length direction for the image data corresponding to the pattern image 61 and the background image 62 stored in the memory based on the determined lengths. To do.

  The moving image texture generation unit 23 similarly determines the length of the corresponding pattern image 61 and the length of the background image 62 for the partial region 52 and the partial region 53 as well. Then, the moving image texture generation unit 23 combines the three pattern images 61 and the three background images 62 corresponding to the partial areas 51 to 53 so as to be connected to each other in the order of the partial areas 51 to 53 in the grid line 41. By doing so, the moving image texture 63 in which the pattern image 61 and the background image 62 having a length corresponding to the inclination angle θ are alternately arranged three by three is generated.

  The moving image texture reproduction unit 24 arranges the generated moving image texture 63 on the grid line 41, and then starts reproducing the moving image texture 63. The moving image texture reproduction unit 24 reproduces the moving image texture 63 at a constant reproduction speed. The reproduction procedure is as follows, for example. The moving image texture generation unit 23 arranges the moving image texture 63 on the grid line 41 in a certain frame, and then generates the next moving image texture 63 to be arranged on the grid line 41 in the next frame from the moving image texture 63. At that time, a certain range (offset) at one end where the height of the corresponding terrain object image 32 is lower in the moving image texture 63 in a certain frame is cut out, and the cut out fixed range is connected to the other end of the moving image texture 63. The moving image texture reproduction unit 24 arranges the next moving image texture 63 thus generated on the grid line 41 in the next frame. As a result, the position of each pattern image 61 in the moving image texture 63 displayed in the next frame is greater than the position of each pattern image 61 in the moving image texture 63 displayed in the previous frame. The height is shifted to the lower side. By repeating this, the moving image texture 63 is reproduced so that the background image 62 moves on the terrain object image 32 from a higher position to a lower position. As a result, an animation image corresponding to the moving image texture 63 is displayed on the display 12. The reproduction speed of the moving image texture 63 is the same regardless of the inclination angle θ defined at the position where the moving image texture 63 is arranged in the terrain object image 32.

  In the present embodiment, an α value is set as a parameter of a value corresponding to the inclination angle θ and the position of the grid line 41. Here, it is preferable to set the α value of the entire background image 62 to be a predetermined value when a predetermined condition such that the α value falls below a predetermined threshold is satisfied. For example, if the α value of the entire background image 62 is set to 0, the portion corresponding to the second range of the grid line 41 can be displayed on the display 12 transparently, and only the pattern image 61 is displayed in the grid. An effect can be produced along the line 41. As a result, the user can easily visually grasp the length of the pattern image 61 and the reproduction speed of the moving image texture 63. Further, if the α value of the entire background image 62 is set to 1, the portion corresponding to the second range in the grid line 41 can be expressed by the color tone or the pattern, and therefore the portion corresponding to the background image 62 is represented by the grid. It can also be visually displayed on the display 12 as a line 41.

  FIG. 5 is a diagram illustrating a procedure for generating the moving image texture 63 when the inclination angle θ is larger. In the example of this figure, the inclination angle θ defined at the position to which the grid line 41 is assigned in the terrain object image 32 is larger than the inclination angle θ shown in FIG. That is, the degree of inclination of the assigned position of the grid line 41 is larger. The three divisions of the grid lines 41 are the same as those in FIG. The moving image texture generation unit 23 sets the inclination angle θ and an α value corresponding to the position at each position in the partial areas 51 to 53. FIG. 5 shows an example in which an α value is set in the partial region 52 as a representative.

  Similarly to FIG. 4, the moving image texture generation unit 23 sets “0” as the α value at the position (left end) where the height of the topographic object image 32 in the partial region 52 is the lowest. Further, as the position in the partial region 52 moves from the left end toward the right end, the α value at each position varies in a straight line rising upward at an angle θ corresponding to the inclination angle θ of the terrain object image 32. The α value is set at each position. The moving image texture generation unit 23 sets an α value of “1” at the maximum. As shown in FIG. 5, after an α value of “1” is set for a certain position of the partial area 52, an α value of “1” is set for all positions on the right side of the α.

  The method for determining the lengths of the background image 62 and the pattern image 61 based on the α value is the same as in FIG. In FIG. 5, since the inclination angle θ is larger than that in FIG. 4, the first range in which the α value is equal to or greater than the predetermined threshold in the partial region 52 is longer than that in FIG. The second range which is less than is shorter than FIG. Therefore, the moving image texture generation unit 23 defines a longer first range and a shorter second range, respectively.

  The angle θ for setting the α value is basically the same as the inclination angle θ, but on the other hand, an upper limit value may be set. When the tilt angle θ exceeds the upper limit value, the angle θ for setting the α value is the upper limit value regardless of the tilt angle θ. Thereby, since the upper limit of the length of the pattern image 61 included in the moving image texture 63 can be provided, it is possible to prevent almost all of the moving image texture 63 from being occupied by the pattern image 61 when the inclination angle θ is very large. .

  In the present embodiment, as shown in FIGS. 4 and 5, the number of pattern images 61 included in the moving image texture 63 is the same regardless of the inclination angle θ defined in the terrain object image 32 on which the moving image texture 63 is arranged. It is. Although not particularly illustrated, the reproduction speed of the moving image texture 63 is constant regardless of the inclination angle θ. On the other hand, as shown in FIGS. 4 and 5, the length of the pattern image 61 included in the moving image texture 63 changes according to the inclination angle θ. Specifically, the pattern image 61 becomes longer as the inclination angle θ is larger. The user grasps the degree of inclination of the position where the pattern image 61 moves in the terrain object image 32 through the length of each pattern image 61 moving on the terrain object image 32 on the play screen. Therefore, the user can intuitively and easily grasp the degree of inclination of each position of the terrain object image 32.

  Further, the terminal device 1 does not synthesize a plurality of unit images in which the background and the pattern are integrated, but synthesizes both the background image 62 and the pattern image 61 that are separated from each other, thereby generating the moving image texture 63. Generate. Thereby, the relationship between the background image 62 and the pattern image 61 included in the moving image texture 63 can be easily changed to an aspect corresponding to the inclination. For example, as shown in FIG. 5, the larger the inclination angle θ, the longer the pattern image 61 and the shorter the background image 62 can be made. Therefore, the terminal device 1 can flexibly change the display mode of the moving image texture 63.

  4 and 5, the terminal device 1 causes the display 12 to display a pattern image 61 and a background image 62 that are alternately arranged on the grid line 41. Further, the terminal device 1 displays a longer pattern image 61 on the display 12 as the degree of inclination (for example, the inclination angle θ) is larger, and the same number of pattern images 61 on the display 12 regardless of the degree of inclination. Display. Accordingly, the user can intuitively and easily grasp the degree of inclination of the terrain object image 32 through the length of the pattern image 61.

[Embodiment 2]
Embodiment 2 according to the present invention will be described below with reference to FIG. The configuration of the terminal device 1 according to the present embodiment is the same as that of the first embodiment. On the other hand, the method for generating and reproducing the moving image texture 63 according to the present embodiment is different from that of the first embodiment.

  FIG. 6 is a diagram illustrating a procedure for generating the moving image texture 63. In the example of this figure, the display of the terrain object image 32, the assignment of the grid lines 41, and the three divisions of the grid lines 41 are the same as in the first embodiment. However, the moving image texture generation unit 23 does not set the α value in the partial areas 51 to 53 after dividing the grid line 41. In other words, the moving image texture 63 is generated without using the α value.

  Specifically, the moving image texture generation unit 23 determines the length of the background image 62 based on the length of a predetermined range (for example, half) on the left side in the partial region 51 regardless of the inclination angle θ defined in the terrain object image 32. To decide. Further, the length of the pattern image 61 is determined based on the length of a predetermined range (for example, half) on the right side in the partial region 51. The moving image texture generation unit 23 similarly determines the length of the corresponding pattern image 61 and the length of the background image 62 for the partial region 52 and the partial region 53 as well. The moving image texture generation unit 23 combines the three pattern images 61 and the three background images 62 corresponding to the partial areas 51 to 53 so as to be connected to each other in the order of the partial areas 51 to 53 in the grid line 41. . Thereby, the moving image texture 63 in which the pattern image 61 and the background image 62 are alternately arranged three by three is generated.

  The moving image texture reproduction unit 24 arranges the generated moving image texture 63 on the grid line 41 and starts reproducing the moving image texture 63. Unlike the first embodiment, the moving image texture reproduction unit 24 sets the reproduction speed of the moving image texture 63 according to the inclination angle θ defined at the position where the moving image texture 63 (or the grid line 41) is arranged in the terrain object image 32. Change. Specifically, the reproduction speed is further increased as the inclination angle θ is larger. Note that the moving image texture reproduction unit 24 reproduces the moving image texture 63 so that the pattern image 61 moves from a higher position to a lower position in the terrain object image 32 as in the first embodiment.

  Thereby, the user can grasp the degree of inclination of the terrain object image 32 through the moving speed of each pattern image 61 on the play screen. Therefore, the user can intuitively and easily grasp the inclination of each position of the terrain object image 32.

[Preferred form]
A preferred embodiment of the present invention will be described below with reference to FIG. The present embodiment is characterized in that the moving image texture generation unit 23 changes the background image 62 included in the moving image texture 63 to a display form corresponding to the height of the position where the moving image texture 63 is arranged. Hereinafter, as an example of the display form of the background image 62, an aspect in which the background image 62 is colored in a color corresponding to the height will be described. This embodiment is applicable to both the first and second embodiments.

  FIG. 7 is a diagram illustrating a procedure for generating the moving image texture 63 including the colored background image 62. First, the moving image texture generation unit 23 generates a moving image texture 63 in which the pattern images 61 and the background images 62 are alternately arranged according to the procedure of the first or second embodiment. Further, each background image 62 is colored in a color corresponding to the height of the position of the terrain object image 32 corresponding to the display position of the background image 62 when the moving image texture 63 is arranged on the grid line 41. In this embodiment, the moving image texture generation unit 23 sets a predetermined coloring rule 71 corresponding to the inclination, and colors each background image 62 included in the moving image texture 63 based on the coloring rule 71.

  The procedure for setting the coloring rule 71 is as follows. First, the moving image texture generation unit 23 specifies a vertex 42 a and a vertex 42 b on the side corresponding to the short side of the grid line 41 among the three sides of the triangular polygon 42. Then, the height of each position corresponding to the vertex 42a and the vertex 42b in the terrain object image 32 is specified. Furthermore, the height of the position corresponding to the midpoint 42c of the vertex 42a and the vertex 42b in the terrain object image 32 is calculated by averaging the height of the specified vertex 42a and the height of the vertex 42b. Hereinafter, the height of this position is referred to as the height at one end of the grid line 41.

  The moving image texture generation unit 23 specifies the vertex 43 a and the vertex 43 b on the side corresponding to the short side of the grid line 41 among the three sides of the triangular polygon 43. And the height of each position corresponding to these vertices 43a and 43b in the terrain object image 32 is specified. Further, the height of the position corresponding to the midpoint 43c of the vertex 43a and the vertex 43b in the terrain object image 32 is calculated by averaging these specified heights. Hereinafter, the height of this position is referred to as the height at one end of the grid line 41.

  Next, the moving image texture generation unit 23 specifies the height of the position where the player character image 31 is arranged in the terrain object image 32. And among one end part of the grid line 41 and the other end part of the grid line 41, red is set to the higher side than the arrangement position of the player character image 31, and blue is set to the lower side. Furthermore, the moving image texture generation unit 23 sets the gradation of each color by setting from one end to the other end of the grid line 41. By these processes, the coloring rule 71 for the grid line 41 is set. The coloring rule 71 is actually applied not to the grid line 41 but to the moving image texture 63 arranged on the grid line 41.

  In FIG. 7, the moving image texture generation unit 23 sets a coloring rule 71 including a certain range of colors 81 to 86 that form a six-step gradation. Color 81 is blue and color 86 is red. From color 81 to color 86, the bluish color gradually decreases and the redness increases. In FIG. 7, for convenience of explanation, six levels of gradation are shown. However, the present invention is not limited to this, and the moving image texture generation unit 23 can arbitrarily set the gradation coloring rules 71 of the levels. Each background image 62 may have a color gradation.

  The moving image texture generation unit 23 colors each background image 62 included in the moving image texture 63 based on the set coloring rule 71. Specifically, each background image 62 is colored in a color arranged at a corresponding position in the coloring rule 71. In the example of FIG. 7, the leftmost background image 62 in the moving image texture 63 is colored with a color 81, the central background image 62 in the moving image texture 63 is colored with a color 83, and the central background image 62 in the moving image texture 63 is colored 85. Color with. Thereby, in the moving image texture 63, the color of each background image 62 changes stepwise from one end portion to the other end portion of the moving image texture 63.

  The moving image texture reproduction unit 24 reproduces the moving image texture 63 in which the background image 62 is colored. In this embodiment, the moving image texture generation unit 23 cuts an offset from one end of the moving image texture 63 before the background image 62 is colored, and adds an offset to the other end of the moving image texture 63 before the background image 62 is colored. By joining together, the next moving image texture 63 in which the background image 62 is not colored is first generated. Then, by coloring each background image 62 included in the next moving image texture 63 in which the background image 62 is not colored based on the coloring rule 71, the next moving image texture 63 reproduced in the next frame is completed. That is, in any frame, the background image 62 arranged at the same position in the moving image texture 63 is colored in the same color corresponding to the coloring rule 71.

  Thus, when the moving image texture 63 is reproduced, the pattern image 61 is displayed so as to move, and the colored background image 62 is displayed so as not to move. Therefore, the user can visually recognize the pattern image 61 as if it is moving on a line colored stepwise based on the coloring rule 71. Further, when the viewpoint in the game screen is changed by a user operation input, the moving image texture 63 is similarly generated and displayed on the grid line 41 along the terrain object image 32 viewed from the changed viewpoint. Can be made. At that time, by performing the above processing for each frame, even when the viewpoint is switched, the moving image texture 63 that can easily allow the user to grasp the inclination and height of the terrain is generated flexibly. be able to.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims. Embodiments obtained by appropriately combining technical means disclosed in different embodiments are also included in the technical scope of the present invention. A new technical feature can also be formed by combining the technical means disclosed in each embodiment.
