Description

Image processing apparatus, image processing method, information recording medium and program {IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, DATA STORAGE MEDIUM, AND PROGRAM}

The present invention relates to an image processing apparatus, an image processing method, an information recording medium, and a program suitable for simply expressing the movement of a rocking motion (shake or vibration).

In the field of games and the like, various studies have been made to make images representing virtual spaces look more realistic. For example, in patent document 1, the shape of a sleeping object is deformed with time, and the situation which the wave of a water surface shakes is represented and the wave is made to look more real. For example, Patent Literature 2 expresses a situation in which a grass or the like shakes due to the flow of water or wind by causing distortion in the object image according to a distance from a fixed point.

JP2002-216159 A JP2005-346165 A

However, according to the prior art as described above, since the object covered with a myriad of polygons is deformed and a texture image is attached, a vertex of the polygon has to be recalculated in accordance with the fluctuation, resulting in a relatively high load process.

The present invention solves this problem, and an object thereof is to provide an image processing apparatus, an image processing method, an information recording medium and a program suitable for simply expressing the movement of the shaking motion.

In order to achieve the above object, the following invention is disclosed in accordance with the principles of the present invention.

An image processing apparatus according to the first aspect of the present invention includes a storage unit, an update unit, and a generation display unit.

The storage unit stores the positions and the shapes of the first polygonal region pasting the first texture image and the second polygonal region pasting the second texture image, respectively.

The update unit may set positions of vertices other than end points of the predetermined sides of the first polygonal region and the second polygonal region at a first period for the first polygonal region and at a second period for the second polygonal region. The shapes stored in the storage unit are updated so as to vibrate and change the shapes.

The generation display unit attaches the first texture image to the first polygonal region and generates and displays an image to which the second texture image is attached to the second polygonal region based on the position and shape stored in the storage unit.

The image processing apparatus of the present invention attaches a texture image to a polygonal region arranged in the virtual space, and generates and displays an image of the situation in the virtual space including the polygonal region in the direction of the eye from the position of the viewpoint in the virtual space. . The polygonal region is, for example, a rectangle such as a rectangle, a square, a parallelogram, a trapezoid, or a shape such as a triangle. The image processing apparatus can set the polygonal region at an arbitrary position in the virtual space. In the texture image, a picture of the object to express fluctuations is drawn. For example, a picture of a leaf is drawn to express a situation where a leaf is swaying in the wind, and a picture of a plant is drawn on a texture image that is a still image when it is desired to express a situation where a plant is shaking by the flow of water. .

The polygonal region has a first polygonal region and a second polygonal region, each of which is variable in shape. The image processing apparatus deforms the shape of the first polygonal area to vibrate at the first period, and deforms the shape of the second polygonal area to vibrate at the second period. The first period and the second period may be the same or different. In addition, the amplitude of vibration may be the same or may differ. The image processing apparatus then attaches the first texture image to the deformed first polygonal region and attaches the second texture image to the deformed second polygonal region. The first texture image and the second texture image may be the same or different.

For example, if the shape of the first polygonal region and the second polygonal region is changed to vibrate gradually at regular timing such as vertical synchronization interruption, a picture (eg, a leaf) drawn on the first texture image and the second texture image is changed. An animation showing a situation in which a picture such as a plant, plants, etc., swings up, down, left and right, etc. is displayed. According to the present invention, the image processing apparatus can express the movement of the shaking only by performing the deformation processing of the figure in the UV space with a relatively small computational load, such as changing the shape of the polygonal region where the texture image is pasted.

The update unit performs affine transformation on the first texture image to deform the first texture image by matching the positions of the predetermined sides of the first polygonal region and the second polygonal region to affine the second texture image. You may convert and deform | transform.

That is, the image processing apparatus can employ an affine transformation using a predetermined affine matrix that transforms a figure by moving, rotating, inverting, enlarging or reducing it as a deformation method of the first polygonal region and the second polygonal region. By changing each matrix element of the affine matrix, various modification methods can be realized.

The first polygonal region and the second polygonal region may exist on the same plane in the virtual space.

The update unit may change the shape of the first polygonal region and the corresponding shape of the second polygonal region by deforming the second polygonal region in a direction opposite to the direction in which the first polygonal region is deformed.

For example, the shapes of the first polygonal region and the second polygonal region in the initial state (the state before the swinging) are both rectangular, and the first polygonal region is inclined in a predetermined direction to deform into a parallelogram, and the second polygonal region Is transformed into a parallelogram by tilting in a direction opposite to the predetermined direction. The shapes of the first polygonal region and the second polygonal region are changed to vibrate with time. Then, it is possible to express the movement of the shaking as if trembling in the same place. That is, by plurally drawing a picture of an object having only one, such as an afterimage, a situation in which the object is shaking or moving can be intuitively understood by the user. However, the shape is not limited to rectangular or parallelogram.

An image processing apparatus according to another aspect of the present invention includes a storage unit, an update unit, and a generation display unit.

The storage unit stores the positions and shapes of the polygonal regions to which one or a plurality of texture images are pasted.

The updating unit updates the shape stored in the storage unit so that the positions of the vertices other than the end points of the predetermined one side of the polygonal area are vibrated at predetermined intervals in the direction in which the predetermined one extends.

The generation display unit generates and displays an image in which one or a plurality of the texture images are attached to the polygonal region based on the position and shape stored in the storage unit.

The shape of the polygonal region is variable. The predetermined side of the figure constituting the polygonal region is invariant in position before and after the change in shape. This predetermined side is called a fixed side. The image processing apparatus deforms the shape of the polygonal region so as to vibrate in the direction in which the fixed side extends at predetermined intervals. The image processing apparatus then attaches a predetermined texture image to the deformed polygonal region. There may be one texture image or a plurality of texture images.

For example, if the polygon shape is gradually changed to vibrate at regular timing such as vertical synchronization interruption, the picture drawn on the texture image (for example, a picture such as a leaf or a plant) may swing left and right, up and down. An animation representing the situation is displayed. According to the present invention, the image processing apparatus can express the movement of the shaking only by performing the deformation processing of the figure in the UV space with a relatively small computational load, such as changing the shape of the polygonal region where the texture image is pasted.

The updating unit may further update the shape stored in the storage unit so that the positions of vertices other than the end points of the predetermined one side are vibrated at the predetermined period in a direction perpendicular to the direction in which the predetermined one side extends.

That is, the shape of the polygonal region is distorted in the direction in which the fixed side extends, and also in the direction perpendicular to the direction in which the fixed side extends. For example, a picture drawn on a texture image may be stretched so that it does not look unnatural. According to the present invention, a more natural movement of the rocking motion can be expressed simply.

The updating unit may update the shape stored in the storage unit so as to fix the predetermined side and vibrate at the predetermined cycle.

In the present invention, the first polygonal region and the second polygonal region are arranged such that one predetermined side of the polygon representing the first polygonal region and one predetermined side of the polygon representing the second polygonal region exist on the same straight line. That is, the fixed side of the polygon representing the first polygonal area and the fixed side of the polygon representing the second polygonal area are arranged on the same straight line.

For example, when it is desired to express the situation in which the leaves are shaken by the wind, a fixed edge is provided at a position including the root portion of the leaves as the direction of the branch where the leaves are growing. For example, when it is desired to express the situation in which the plants are shaken by the wave, a fixed edge is provided at the position including the root part of the plants in the direction of the ground where the plants are growing. By providing a fixed side in this way, it is possible to more easily express the situation in which the object is shaking. In addition, before and after each deformation | transformation of a 1st polygonal area and a 2nd polygonal area | region, it is preferable to make the position of a fixed edge constant.

An image processing method according to another aspect of the present invention is an image processing method executed in an image processing apparatus including a storage unit, an update unit, and a generation display unit, and includes an update step and a generation display step.

The storage unit stores the positions and shapes of the first polygonal region to which the first texture image is attached and the second polygonal region to which the second texture image is attached.

The updating step includes positions of vertices other than the end points of the predetermined one sides of the first polygonal region and the second polygonal region at a first period for the first polygonal region, and a second for the second polygonal region. The update unit updates the shape stored in the storage unit so as to vibrate each cycle to change the shape.

In the generation display step, the generation display unit attaches the first texture image to the first polygonal region and attaches the second texture image to the second polygonal region based on the position and shape stored in the storage unit. Create and display

According to the present invention, it is possible to easily express the movement of the shaking motion only by performing the deformation processing of the figure in the UV space having a relatively small computational load, such as changing the shape of the polygonal region where the texture image is pasted.

An information recording medium according to another aspect of the present invention functions a computer as a storage unit, an update unit, and a generation display unit.

The storage unit stores the positions and shapes of the first polygonal region to which the first texture image is pasted and the second polygonal region to which the second texture image is pasted.

The shapes stored in the storage unit are updated so as to vibrate and change the shapes.

The generation display unit attaches the first texture image to the first polygonal region and generates and displays an image to which the second texture image is attached to the second polygonal region based on the position and shape stored in the storage unit.

Further, the CPU 101 uses arithmetic logic units (ALUs) (not shown) for a storage area capable of fast access such as a register (not shown), an arithmetic operation such as addition or subtraction, logical sum, logical product, logical irregularity, or the like. Logic operations, bit sums, bit products, bit inversions, bit operations such as bit shifts, bit rotations, and the like can be performed. In addition, the CPU 101 itself is configured or a coprocessor may be realized so as to perform saturation operations such as addition and subtraction systems for multimedia processing, vector operations such as trigonometric functions, and the like at high speed.

In the ROM 102, an IPL (Initial Program Loader) to be executed immediately after power-on is recorded. When this is executed, the program recorded in the DVD-ROM is read into the RAM 103, and execution by the CPU 101 starts. do. The ROM 102 also records programs and various data of the operating system required for the operation control of the entire information processing apparatus 100.

The RAM 103 is for temporarily storing data and programs. The RAM 103 holds programs and data read from the DVD-ROM, and data necessary for the progress and chat communication of other games. In addition, the CPU 101 provides a variable area in the RAM 103 and operates by directly operating an ALU with respect to the value stored in the variable, or once stores the value stored in the RAM 103 in a register. After that, arithmetic operations are performed on the registers, and the processing results are rewritten into memory.

The external memory 106, which is detachably connected via the interface 104, includes data representing game play status (historical scores, etc.), data representing game progression status, and log of game chat communication using a network. (Record) The data and the like can be recorded again. The user can appropriately write these data to the external memory 106 by inputting an instruction via the controller 105.

In the DVD-ROM mounted in the DVD-ROM drive 107, a program for realizing a game and image data or audio data accompanying the game are recorded. Under the control of the CPU 101, the DVD-ROM drive 107 reads out a DVD-ROM attached thereto, reads out necessary programs and data, and these are temporarily stored in the RAM 103 or the like. .

The image processing unit 108 processes the data read out from the DVD-ROM by an image computing processor (not shown) included in the CPU 101 or the image processing unit 108, and then the image processing unit 108 includes the data. Write to a frame memory (not shown). The image information recorded in the frame memory is converted into a video signal at a predetermined synchronization timing and output to a monitor (not shown) connected to the image processing unit 108. This makes it possible to display various images.

The image calculation processor can execute a superimposition operation of two-dimensional images, a transmission operation such as alpha blending, and various saturation operations at high speed.

3A is a diagram illustrating an example of a first texture image 310 attached to an area (hereinafter referred to as a "polygonal area") displayed by a figure arranged in a virtual space. In this drawing, as an example, a picture of a leaf is drawn in the first texture image 310.

3B is a diagram illustrating an example of the second texture image 320 pasted onto the polygonal region disposed in the virtual space. In this drawing, as an example, a picture of a leaf different from the first texture image 310 is drawn on the second texture image 320.

4 is a diagram for describing a polygonal area in the screen 400 displayed on the monitor. The polygonal region includes a first polygonal region 410 and a second polygonal region 420.

The image processing apparatus 200 according to the present embodiment changes the shape by performing image transformation such as affine transformation on a figure representing the first polygonal region 410, and changes the shape to the first polygonal region 410 after the image transformation. Paste the texture image 310. In addition, the image processing apparatus 200 performs image transformation such as affine transformation on a figure representing the second polygonal region 420 to change the shape, and a second texture image on the second polygonal region 420 after the image transformation. Attach (320). The image processing apparatus 200 displays the image obtained by rendering in this way on the screen 400. It will be described in detail below.

First, each part of the image processing apparatus 200 is demonstrated. The image processing apparatus 200 includes a storage unit 201, an update unit 202, and a generation display unit 203.

The storage unit 201 stores the first sticking area information 251 and the second sticking area information 252. The CPU 101 and the RAM 103 work together to function as the storage unit 201.

The first pasting area information 251 is information specifying the position and shape of the first polygonal area 410 to which the first texture image 310 as shown in Fig. 3A is to be pasted. Similarly, the second pasting area information 252 is information specifying the position and shape of the second polygonal area 420 to which the second texture image 320 as shown in FIG. 3B is to be pasted.

The positions of the first polygonal region 410 and the second polygonal region 420 are respectively displayed as coordinate values in the X-Y coordinate system defined on the screen 400. For example, by specifying coordinate values such as any vertex or center point of the figure constituting the first polygonal region 410, the position of the first polygonal region 410 on the screen 400 is uniquely determined. do. The same applies to the second polygonal region 420.

The first polygonal region 410 and the second polygonal region 420 are disposed on the same plane in the virtual space.

The shapes of the first polygonal region 410 and the second polygonal region 420 are, for example, triangular and rectangular (typically rectangular or trapezoidal).

As will be described later, the CPU 101 may change the position and shape of the first polygonal area 410. Similarly, the CPU 101 may change the position and shape of the second polygonal area 420.

The first polygonal region 410 and the second polygonal region 420 may be set in the screen 400 one by one or several. When a plurality of first polygonal regions 410 (or second polygonal regions 420) are set, the memory unit 201 is positioned at each of the first polygonal regions 410 (or second polygonal regions 420). And first sticking area information 251 (or second sticking area information 252) indicating a shape.

In addition, the storage unit 201 stores the positions (coordinate values) of all the vertices of the figure constituting the first polygonal area 410 as the first pasted area information 251, thereby storing the first polygonal area 410. You can also determine the shape of. For example, the CPU 101 sets a line segment connecting neighboring vertices as one side of a figure representing the first polygonal region 410. The CPU 101 can obtain a line segment for all neighboring vertices, and can make the shape created by combining the obtained line segments into the shape of the first polygonal region 410. The same applies to the second polygonal region 420.

The storage unit 201 stores in advance a first texture image 310 attached to the first polygonal region 410 and a second texture image 320 pasted to the second polygonal region 420.

In the first texture image 310, there are a transparent region 315 and an opaque region 316. The opaque region 316 is an image region drawn using a non-transparent color, for example, the picture of the leaf. The transparent region 315 is a region other than the opaque region 316. Similarly, the second texture image 320 also has a transparent region 325 and an opaque region 326.

The storage unit 201 stores the first attachment area information 251, the second attachment area information 252, the first texture image 310, and the second texture image 320, such as the external memory 106. You may store it in memory.

Next, the update unit 202 matches one predetermined side of each of the first polygonal region 410 and the second polygonal region 420 at a certain point in time, and positions of vertices other than the end points of the predetermined one side. The first patch region information 251 and the second patch region information are oscillated at a first cycle for the first polygonal region 410 and at a second cycle for the second polygonal region 420 to change the shape. Update 252. The CPU 101, the RAM 103, and the image processing unit 108 cooperate to function as the update unit 202.

In the first polygonal region 410 and the second polygonal region 420, local coordinate systems (U-V coordinate systems) are defined, respectively.

5A, 5B, and 5C are views illustrating a situation in which the shape of the first polygonal region 410 is changed.

6A, 6B, and 6C are views illustrating a situation in which the shape of the second polygonal region 420 is changed. The case where the shape of the 1st polygonal area | region 410 in the state (initial state) before changing shape is made into rectangle for the understanding of this invention is demonstrated as an example.

5A to 5C and 6A to 6C, a first texture image 310 is pasted in the first polygonal region 410, and a second texture image (in the second polygonal region 420). Although 320 is pasted, the processing of attaching the first texture image 310 and the second texture image 320 to the first polygonal region 410 and the second polygonal region 420, respectively, is performed in the display unit 203. In the description of the configuration, it will be described in detail.

The CPU 101 transforms the figure representing the first polygonal region 410 by an affine transformation using a predetermined affine matrix. FIG. 5A shows the first polygonal region 410 in the state before the affine transformation (initial state). 5B and 5C show the first polygonal region 410 after the affine transformation.

The CPU 101 determines a line segment connecting two vertices 511 and 512 to which the first polygonal region 410 is adjacent to the predetermined one side (hereinafter, referred to as a “fixed side”) 510. It is done. The fixed side 510 is invariant in position before and after affine transformation.

In the following description, the parameter indicating the magnitude of the movement amount with respect to the U-axis direction of the side (line segment connecting two vertices 513 and 514) of the fixed side 510 is indicated by "L". A parameter indicating the magnitude of the angle at which one side indicated by a line segment connecting vertices 512 and 513 and one side indicated by a line segment connecting vertices 511 and 514 is expressed as "θ". Display.

Similarly, a parameter indicating the magnitude of the movement amount in the U-axis direction of the opposite side of the fixed side 610 (the line segment connecting the two vertices 613 and 614) is indicated by "M". A parameter indicating the magnitude of the angle at which one side indicated by a line segment connecting vertices 612 and 613 and one side indicated by a line segment connecting vertices 611 and 614 is expressed as "φ". Display.

The first texture when the generation display unit 203 described later attaches the first texture image 310 to the first polygonal region 410 and also attaches the second texture image 320 to the second polygonal region 420. The position of the opaque region 515 on the fixed side 510 of all the pixel data constituting the image 310 and the opaque region 615 on the fixed side 610 of the all pixel data constituting the second texture image 320. The positions of are preferably the same.

For example, before and after deformation of the first polygonal region 410 and the second polygonal region 420 by the update unit 202, the root portions of the leaves drawn on the first texture image 310 and the second texture The first texture image 310 and the second texture image 320 are created so that the root portions of the leaves drawn on the image 320 always match. In this way, the movement of the swinging of the leaves becomes more natural.

For example, as shown in FIG. 5B, the CPU 101 connects the opposite sides (two vertices 513 and 514) of the fixed side 510 while fixing the position and the direction of the fixed side 510. The first polygonal region 410 is deformed from a rectangle to a parallelogram by moving the line segment in parallel in the negative direction of the U axis. In other words, the CPU 101 inclines both the one side indicated by the line segment connecting the vertices 512 and 513 and the one side indicated by the line segment connecting the vertices 511 and 514 by an angle θ. To deform, the first polygonal region 410 is deformed.

The distance L is variable in the range of 0 ≦ L ≦ LA. The angle θ is variable in the range of 0 ≦ θ ≦ θ A. The deformations shown in this figure are generally called shear deformations.

For example, as shown in FIG. 5C, the CPU 101 moves the opposite side of the fixed side 510 in the positive direction of the U axis by a distance L in parallel with the first polygon, while fixing the fixed side 510. Region 410 is transformed from rectangular to parallelogram. In other words, the CPU 101 inclines both the one side indicated by the line segment connecting the vertices 512 and 513 and the one side indicated by the line segment connecting the vertices 511 and 514 by an angle θ. The first polygonal region 410 is deformed.

The distance L is variable in the range of 0 ≦ L ≦ LB. The angle θ is variable in the range of 0 ≦ θ ≦ θ B.

For example, the CPU 101 may combine the strain shown in FIG. 5B with the strain shown in FIG. 5C. In other words, the CPU 101 vibrates so that the stool of the fixed side 510 moves in parallel in the negative direction of the U axis as much as LA and in the positive direction of the U axis as much as LB with the passage of time. Let's do it.

In other words, the CPU 101 has one side indicated by a line segment connecting vertices 512 and 513 and one side indicated by a line segment connecting vertices 511 and 514 in the negative direction of the U axis. Is oscillated so as to be inclined at most by θ A and at most in the positive direction of the U axis by θ B. The period of each vibration may be same or different.

The CPU 101 updates the first pasting area information 251 by using the information indicating the position and shape of the changed first polygonal area 410.

Similarly, the CPU 101 transforms the figure representing the second polygonal region 420 by an affine transformation using a predetermined affine matrix. FIG. 6A shows the second polygonal region 420 in the state before the affine transformation (initial state). 6B and 6C show the second polygonal region 420 after the affine transformation.

The CPU 101 sets the line segment connecting the two adjacent vertices 611, 612 of the second polygonal region 420 as the fixed side 610. Like the fixed side 510, the fixed edge 610 is invariant before and after affine transformation.

For example, as shown in FIG. 6B, the CPU 101 moves the opposite side of the fixed side 610 by the distance M in parallel in the negative direction of the U axis while fixing the position and the direction of the fixed side 610. The second polygonal region 420 is transformed from a rectangular to a parallelogram. In other words, the CPU 101 is configured such that one side indicated by the line segment connecting the vertices 612 and 613 and one side indicated by the line segment connecting the vertices 611 and 614 are inclined by an angle φ. The second polygonal region 420 is deformed.

The distance M is variable in the range of 0 ≦ M ≦ MA. The angle φ is variable in the range of 0 ≦ φ ≦ φ A.

For example, as shown in FIG. 6C, the CPU 101 moves the opposite side of the fixed side 610 in parallel with the distance M in the positive direction of the U axis, while fixing the fixed side 610 to form the second polygon. Region 420 is deformed from a rectangle to a parallelogram. In other words, the CPU 101 is configured such that one side indicated by the line segment connecting the vertices 612 and 613 and one side indicated by the line segment connecting the vertices 611 and 614 are inclined by an angle φ. The second polygonal region 420 is deformed.

The distance L is variable in the range of 0 ≦ M ≦ MB. The angle φ is variable in the range of 0 ≦ φ ≦ φ B.

For example, the CPU 101 may combine the strain shown in FIG. 6B with the strain shown in FIG. 6C. That is, the CPU 101 vibrates so as to move the opposite side of the fixed side 610 in parallel in the negative direction of the U axis as much as MA and in the positive direction of the U axis as much as MB in time with the passage of time. Exercise In other words, the CPU 101 has one side indicated by a line segment connecting the vertices 612 and 613 and one side indicated by a line segment connecting the vertices 611 and 614 in the negative direction of the U axis. As a result, it vibrates so as to incline as much as φ A up to φ B in the positive direction of the U axis. The period of each vibration may be same or different.

The CPU 101 updates the second pasting area information 252 with information indicating the position and shape of the changed second polygonal area 420.

A predetermined side of each of the first polygonal region 410 and the second polygonal region 420 coincides at a certain point of time, such that the fixed side 510 and the second polygonal region 420 of the first polygonal region 410 are coincident with each other. It is meant that the fixed side 610 of) coexist on the same straight line at some point in time. "A point in time" typically refers to the initial state before affine transformation. The fixed side 510 of the first polygonal region 410 and the fixed side 610 of the second polygonal region 420 may always exist on the same straight line.

In addition, the CPU 101, as the fixed sides 510 and 610, is used in each of the sides of the polygon representing the first polygonal region 410 and the second polygonal region 420 in accordance with the image to express the fluctuation. It shall select one each suitably. For example, if a leaf hanging on a tree branch intends to express a situation in which the leaf is shaken by the wind, the fixed sides 510 and 610 are set in the direction along the branch where the leaf is growing. For example, if a seaweed such as kelp or seaweed that grows in the sea is intended to represent a situation in which the seaweed moves in accordance with the movement of the sea, the fixed sides 510 and 610 are set in the direction along the seabed where the seaweed is growing. do.

By setting the fixed sides 510 and 610 in this way, it is possible to more easily express the situation in which the object is not shaken, but the object is shaking while the part is fixed.

The shapes of the first polygonal region 410 and the second polygonal region 420 are not limited to rectangles or parallelograms. For example, as shown in FIG. 7A, the shape of the first polygonal region 410 before and after deformation may be an arbitrary quadrangle having vertices 511 to 514. The CPU 101 has vertices 513 and 514 other than the vertices 511 and 512 at both ends of the fixed side 510 reciprocating on the predetermined trajectories 701 and 702, respectively. The first polygonal region 410 may be modified to vibrate. It is preferable that the vibration period of the vertex 513 and the vibration period of the vertex 514 are the same.

For example, as shown in FIG. 7B, the shape of the first polygonal region 410 before and after deformation may be an arbitrary triangle having vertices 511 to 513. The CPU 101 includes the first polygonal region 410 such that vertices 513 other than the vertices 511 and 512 on both ends of the fixed side 510 oscillate reciprocally on a predetermined trajectory 703. ) May be modified.

Similarly, the shape of the second polygonal region 420 may be an arbitrary quadrangle having the vertices 611 to 614 or an arbitrary triangle having the vertices 611 to 613. That is, in FIGS. 7A and 7B, the vertices 511 to 514 may be replaced with the vertices 611 to 614, and the fixed side 510 may be replaced with the fixed side 610.

Next, the generation display unit 203 attaches the first texture image 310 to the first polygonal region 410 based on the first pasted region information 251 stored in the storage unit 201, and stores the storage unit 203. On the basis of the second pasted region information 252 stored in 201, an image obtained by pasting the second texture image 320 in the second polygonal region 420 is generated, and the generated image is displayed on the monitor. The CPU 101, the RAM 103, and the image processing unit 108 cooperate to function as the generation display unit 203.

Specifically, when the shape of the first polygonal area 410 is a quadrangle, as shown in FIG. 8A, the CPU 101 controls the image processing unit 108 to determine the vertices of the first texture image 310. 311 to vertex 511 of first polygonal region 410, vertex 312 to vertex 512, vertex 313 to vertex 513, vertex 314 to vertex 514, respectively. Correspondingly, the first texture image 310 is pasted to the first polygonal region 410.

Similarly, when the shape of the second polygonal region 420 is a quadrangle, the CPU 101 vertices the vertex 321 of the second texture image 320 to the vertex 611 of the second polygonal region 420. 322 to vertex 612, vertex 323 to vertex 613, and vertex 324 to vertex 614, respectively, so that second texture image 320 is second polygonal region 420. Attach to

In the following description, the CPU 101 controls the image processing unit 108 to display the first and second texture images 310 and 320 in the first polygonal region 410 and the second polygonal region 420, respectively. The process of generating an image attached to the above is called an image generation process.

When the shape of the first polygonal region 410 is triangular, as shown in FIG. 8B, the CPU 101 controls the image processing unit 108 to select the vertices 311 of the first texture image 310. The first texture image 310 corresponds to the vertex 511 of the polygon region 410, vertex 312 to vertex 512, and vertex 313 and vertex 314 to vertex 513, respectively. ) Is attached to the first polygonal region 410.

Similarly, when the shape of the second polygonal region 420 is a triangle, the CPU 101 verifies the vertex 321 of the second texture image 320 at the vertex 611 of the second polygonal region 420. The second texture image 320 is pasted to the second polygonal region 420 by 322 corresponding to the vertex 612 and both the vertex 323 and the vertex 324 to the vertex 613, respectively.

9A to 9C show the CPU 101 having the first polygon in the case where the shape, size, and size of the first polygonal region 410 before deformation and the second polygonal region 420 before deformation are the same. The first texture image 310 is pasted to the region 410 and the second texture image 320 is pasted to the second polygonal region 420. 9A is before the deformation of the first polygonal region 410 and the second polygonal region 420, and FIGS. 9B and 9C are after the deformation.

The CPU 101 fixes the position and direction of the fixed side 510 of the first polygonal region 410 and distorts the angle θ per unit time by a predetermined first oscillation period so that the first polygonal region 410 is distorted. To transform. In addition, the CPU 101 fixes the position and direction of the fixed side 610 of the second polygonal region 420, and per unit time in the direction opposite to the deformation direction of the first polygonal region 410 at a predetermined second oscillation period. The second polygonal region 420 is deformed to be distorted by the magnitude of the angle φ.

For example, if the first vibration period (the vibration period of the first polygonal region 410) and the second vibration period (the vibration period of the second polygonal region 420) are the same, the generated image is illustrated in FIGS. 9A and 9B. , FIG. 9A, FIG. 9C, and FIG. 9A. By repeatedly executing the image generating process, the CPU 101 generates an animated image in which leaves are shaken from side to side so that the leaves drawn on the first texture image 310 and the leaves drawn on the second texture image 320 alternately. Can be.

10A and 10B show the first texture image 310 shown in FIG. 3A and the second texture image 320 shown in FIG. 3B, respectively, in the first polygonal region 410 and the second polygonal region (FIG. 4). 420 is an example of an image generated by pasting. In order to facilitate understanding of the present invention, the edges of the first polygonal region 410 and the edges of the second polygonal region 420 are indicated by solid lines, but these edges are not displayed on the monitor.

As shown in FIGS. 10A and 10B, when there are a plurality of first polygonal regions 410 (and / or second polygonal regions 420) in the screen 400, the CPU 101 may determine each of the firsts. For the polygonal region 410 (and / or the second polygonal region 420), affine transformation or the like is performed to change the shape, and the first texture image 310 (and / or the second texture image 320). Attach. The deformation method of each of the first polygonal regions 410 (and / or the second polygonal regions 420) may be the same or different.

For example, a plurality of first polygonal regions 410 (and / or second polygonal regions 420) are set in the screen 400, and all the first polygonal regions 410 (and / or the second polygonal regions) are set. 420) using the same affine matrix to deform and paste the first texture image 310 (and / or the second texture image 320), the first texture image 310 (and / or the second texture). It is possible to generate an image representing a situation in which the picture drawn on the image 320 is shaken up, down, left, and right so that the pictures drawn are the same.

In general, in the field of computer graphics (CG), rendering is often performed using application software called a shader, but according to the present invention, a process of transforming a figure in a UV space having a relatively small computational load is performed. I can express the movement of the shaking only.

Next, an image generation process performed by each of the above-described embodiments will be described using the flowchart of FIG.

First, the CPU 101 displays the first pasting area information 251 indicating the position and shape of the first polygonal area 410 and the second pasting area information 252 indicating the position and shape of the second polygonal area 420. ) Is read from the RAM 103 (step S1101).

The CPU 101 affines a figure (polygon) representing the first polygonal region 410 using a predetermined affine matrix AM1. In addition, the CPU 101 affines the figure representing the second polygonal area 420 using a predetermined affine matrix AM2 (step S1102).

When the deformation by the affine matrix AM1 is reversed from the deformation by the affine matrix AM2, the movement of the shaking motion can be expressed more clearly. For example, as shown in FIGS. 9B and 9C, the CPU 101 distorts the first polygonal region 410 by the angle θ and the second polygonal region 420 by the angle φ in the direction opposite to the direction of the angle θ. Distort as much. However, the direction of deformation is arbitrary. The magnitude | size of angle (theta) and the magnitude | size of angle (phi) may be the same, or may differ.

For example, when the virtual wind is blowing in the virtual space, if the wind is relatively weak, the deformation directions of the first polygonal region 410 and the second polygonal region 420 are reversed. On the other hand, if the wind is relatively strong, the deformation directions of the first polygonal region 410 and the second polygonal region 420 are the same. In this way, it is possible to have a change in the movement of the swing, as the leaves shake slowly when the wind is weak and the leaves flutter when the wind is strong.

The CPU 101 controls the image processing unit 108 to attach the first texture image 310 to the first polygonal region 410 and to attach the second texture image 320 to the second polygonal region 420. (Step S1103). The processing of this step is commonly called rendering.

The CPU 101 updates the first pasting region information 251 with the position and shape of the first polygonal region 410 deformed in step S1102, and similarly deforms the second polygonal region 420 in step S1102. The second pasting area information 252 is updated to the position and shape of the step (step S1104).

The CPU 101 controls the image processing unit 108 to display the image generated in step S1103 on the monitor.

By repeatedly executing this image generation process, for example, every vertical synchronization interruption, an animation representing the movement of the shaking of the object in the virtual space can be created.

In general, the movement of transparent air such as wind and the movement of transparent water in the water are often difficult to express in images. Thus, if the figure where the texture is pasted is modified as in the present invention and the texture is pasted in accordance with the modified figure, the movement of the shaking can be easily expressed while reducing the load on the image processing.

In the present embodiment, two kinds of polygonal regions are set in the screen 400, but three or more kinds of polygonal regions may be set, and the CPU 101 may deform each polygonal region.

(Embodiment 2)

Next, other embodiment of this invention is described. In the above embodiment, two texture images 310 and 320 are used separately, but one texture image common to the first polygonal region 410 and the second polygonal region 420 is used for pasting. You may also In addition, three or more texture images may be used separately.

For example, when generating an image of pudding placed on a plate, as the simplest conventional expression technique, as shown in Fig. 12A, one texture image 1202 is placed in one polygonal region 1201. Just stick it and draw it. On the other hand, in the expression technique used in manga, etc., a situation where one object is shaken or moved may be expressed like an afterimage using a plurality of pictures. For example, when drawing a situation in which the soft pudding is shaking, as shown in Fig. 12B, a situation in which only one pudding is deliberately shaken and some afterimages may be expressed. According to the present invention, it is possible to express a situation in which an object (pudding) is shaken as if it is drawn by the expression technique used in such a cartoon.

That is, as illustrated in FIG. 12C, the first polygonal region 410 and the second polygonal region 420 having the same shape and the same shape in the initial state are set in the screen 400. The common texture image 1202 attached to the first polygonal region 410 and the second polygonal region 420 is prepared in advance.

Next, as shown in FIG. 12D, the CPU 101 deforms the first polygonal region 410 by the angle θ at a predetermined period T1. Similarly, the CPU 101 deforms the second polygonal region 420 in the reverse direction by the angle θ at the same predetermined period T1. In other words, the shapes of the first polygonal region 410 after deformation and the second polygonal region 420 after deformation are in line symmetry with respect to the straight line 1203.

The CPU 101 attaches the texture image 1202 to the deformed first polygonal region 410 and the second polygonal region 420.

As shown in FIG. 13, the CPU 101 changes the angle θ with the passage of time, and repeatedly executes the process of deforming the first polygonal region 410 and the second polygonal region 420. As shown in FIG. 13, when the angle θ is vibrated at a predetermined period T1, a situation in which an object is shaken can be more easily expressed.

(Embodiment 3)

Next, other embodiment of this invention is described. The CPU 101 may deform the first polygonal region 410 and the second polygonal region 420 in a direction perpendicular to the fixed sides 510 and 610.

For example, as shown in FIG. 14A, the CPU 101 fixes the first polygonal region (or the second polygonal region) 1400 before deformation having the vertices 1401 to 1404 by the fixed side 1405. After fixing, it is deformed to be distorted by the angle θ. At this time, the length of each side is made invariant. Then, the first polygonal region (or second polygonal region) 1410 after deformation is lower by ΔL than the first polygonal region (or second polygonal region 1400) before deformation.

14B shows that the CPU 101 controls the image processing unit 108 to attach a predetermined texture image to the deformed first polygonal region 1410, and similarly applies the predetermined texture image to the deformed second polygonal region 1420. It is a figure which shows the image created by pasting. By deforming in the direction perpendicular to the fixed side 1405 in this manner, the texture image does not float in the horizontal direction (the length of the tree is increased), so that it can be expressed naturally according to the shaking situation.

In addition, when pasting a texture image to the first polygonal region 1410 and the second polygonal region 1420 after deformation, the position of the opaque region 1406 on the fixed side 1405 of the pixel data constituting the texture image is invariant. In this way, the shaking situation can be expressed more naturally.

(Embodiment 4)

Next, other embodiment of this invention is described. This embodiment differs from the above embodiment in that the first polygonal area 410 is set in the screen 400 while the second polygonal area 420 is not set.

15A, 15B, and 15C are views illustrating a situation in which the shape of the first polygonal region 410 is changed. In the first texture image 310 attached to the first polygonal region 410, a picture of a plurality of objects to express the movement of the shaking motion is drawn in advance. For example, a picture of a plurality of leaves is drawn in the first texture image 310.

FIG. 15A shows a situation in which the CPU 101 attaches the first texture image 310 to the first polygonal region 410 before the shape conversion. For example, before the shape conversion, the shape of the first polygonal region 410 is made rectangular and the length (height) in the V direction is made L1.

The CPU 101 deforms the first polygonal region 410 by using one side of the first polygonal region 410 as the fixed side 510. For example, as shown in FIG. 15B, the CPU 101 distorts the first polygonal region 410 by an angle θ A in the negative direction of the U axis to deform into a parallelogram. Alternatively, as shown in FIG. 15C, the CPU 101 deforms the first polygonal region 410 by the angle θ B in the positive direction of the U axis to deform into a parallelogram. The CPU 101 attaches the first texture image 310 to the deformed first polygonal region 410.

As shown in FIG. 13, the CPU 101 changes the angle θ to be distorted with the elapsed time. That is, the CPU 101 changes the angle θ so as to reciprocate with the period T1 in the range of θ MIN ≦ θ ≦ θ MAX . The first polygonal region 410 is changed from the shape shown in Fig. 15A to the shape shown in Fig. 15B, and also changed from the shape shown in Fig. 15B to the shape shown in Fig. 15A, and from the shape shown in Fig. 15A to Fig. 15C. It changes to the shape shown, and also changes from the shape shown in FIG. 15C to the shape shown in FIG. 15A. By repeating these changes, the object (in this case, the leaf) is shaken to represent the situation.

In combination with the above embodiments, the CPU 101 may not only change the angle θ, but also change the height of the first polygonal region 410.

16 is a diagram illustrating an example of a relationship between elapsed time and height. The CPU 101 changes the height of the first polygonal region 410 at the same period T1 in accordance with the change in the angle θ shown in FIG. 13. In other words, the change amount ΔL (= LL A or LL B ) of the height of the first polygonal region 410 reciprocates in the period T1 in the range of L MIN ≤ L ≤ L MAX (= L1). By changing the height in this way, the object looks more natural so that the object does not extend in the swinging direction.

According to this embodiment, since the number of polygonal areas which are a texture pasting place can be reduced, a processing burden can be further reduced and the situation in which an object shakes can be represented.

This invention is not limited to embodiment mentioned above, A various deformation | transformation and an application are possible. Moreover, it is also possible to combine each component of embodiment mentioned above freely.
