- the deformation directions of the first polygonal area 410 and the second polygonal area 420 are reversed.
- the deformation directions of the first polygonal area 410 and the second polygonal area 420 are made the same. In this way, it is possible to change the movement of the shaking, such as when the wind is weak, the leaves sway slowly and slowly, and when the wind is strong, the leaves flutter.
- the CPU 101 controls the image processing unit 108 to paste the first texture image 310 in the first polygon area 410 and paste the second texture image 320 in the second polygon area 420 (step S1103).
- the process of this step is generally called rendering.
- the CPU 101 updates the first pasting area information 251 with the position and shape of the first polygonal area 410 deformed at step S1102, and the CPU 101 updates the first polygonal area 420 with the position and shape of the second polygonal area 420 similarly deformed at step S1102.
- the 2 pasting area information 252 is updated (step S1104).
- the CPU 101 controls the image processing unit 108 to display the image generated in step S1103 on the monitor.
- the two texture images 310 and 320 are selectively used.
- the texture image 310 and 320 may be pasted using a single texture image common to the first polygon region 410 and the second polygon region 420. Further, three or more texture images may be used properly.
- the CPU 101 deforms the first polygonal region 410 by an angle ⁇ at a predetermined period T1. Similarly, the CPU 101 deforms the second polygonal region 420 in the reverse direction by the angle ⁇ at the same predetermined period T1.
- the respective shapes of the first polygonal area 410 after deformation and the second polygonal area 420 after deformation have a line-symmetric relationship with respect to the straight line 1203.
- the CPU 101 pastes the texture image 1202 on the deformed first polygon area 410 and the second polygon area 420.
- the CPU 101 repeatedly executes the process of changing the angle ⁇ with time and deforming the first polygonal area 410 and the second polygonal area 420 as shown in FIG. As shown in FIG. 13, when the angle ⁇ is vibrated at a predetermined period T1, it is possible to more easily represent the manner in which the object shakes.
- the CPU 101 can deform the first polygonal area 410 and the second polygonal area 420 in the direction perpendicular to the fixed sides 510 and 610.
- the CPU 101 controls the image processing unit 108 to paste a predetermined texture image on the deformed first polygon area 1410, and similarly paste the predetermined texture image on the deformed second polygon area 1420. It is a figure showing the image which can be attached. By deforming in the direction perpendicular to the fixed side 1405 in this way, the texture image does not extend in the horizontal direction (the tree length increases), so that the state of shaking is more natural. Can be expressed.
- FIG. 15A, FIG. 15B, and FIG. 15C are diagrams showing how the shape of the first polygonal region 410 changes.
- the first texture image 310 to be pasted on the first polygonal region 410 pictures of a plurality of objects that are desired to express the movement of shaking are drawn in advance.
- the first texture image 310 includes a plurality of leaves of trees.
- FIG. 15A shows a state in which the CPU 101 has pasted the first texture image 310 on the first polygonal area 410 before shape conversion.
- the shape of the first polygonal region 410 is a rectangle, and the length (height) in the V direction is L1.
- the CPU 101 deforms the first polygon region 410 by setting one side of the first polygon region 410 as the fixed side 510. For example, as shown in FIG. 15B, the CPU 101 distorts the first polygonal region 410 in the negative direction of the U axis by an angle ⁇ A and transforms it into a parallelogram. Alternatively, as shown in FIG. 15C, the CPU 101 distorts the first polygonal region 410 in the positive direction of the U axis by an angle ⁇ B and transforms it into a parallelogram. Then, the CPU 101 pastes the first texture image 310 on the deformed first polygon region 410.
- the CPU 101 changes the angle ⁇ to be distorted with the elapsed time as shown in FIG. That is, the CPU 101 changes the angle ⁇ so as to reciprocate at a period T1 in the range of ⁇ MIN ⁇ ⁇ ⁇ ⁇ MAX.
- the first polygonal region 410 changes from the shape shown in FIG. 15A to the shape shown in FIG. 15B, further changes from the shape shown in FIG. 15B to the shape shown in FIG. 15A, and further changes from the shape shown in FIG. 15A to FIG.
- the shape changes, and further changes from the shape shown in FIG. 15C to the shape shown in FIG. 15A. By repeating such changes, the object (in this case, the leaves of the tree) is swayed.
- the CPU 101 may change not only the angle ⁇ but also the height of the first polygonal region 410.
- FIG. 16 is a diagram showing an example of the relationship between elapsed time and height.
- the CPU 101 changes the height of the first polygonal region 410 with the same period T1 in accordance with the change of the angle ⁇ shown in FIG.
- the number of polygonal areas to which the texture is applied can be reduced, it is possible to further reduce the processing load and express how the object shakes.
