Wherein, the shape of the 1st polygonal region 410 can also be confirmed as 251 storages of the 1st sticking area information in the position (coordinate figure) on all summits of the figure of storage part 201 through will constituting the 1st polygonal region 410.For example, CPU101 will connect adjacent vertex line segment each other, as one side of the figure of representing the 1st polygonal region 410.CPU101 obtains line segment each other to all adjacent vertexs, and the line segment that connection is obtained and the figure that forms are as the shape of the 1st polygonal region 410.For the 2nd polygonal region 420 too.
And storage part 201 is stored the 1st texture image 310 that the 1st polygonal region 410 is pasted and the 2nd texture image 320 that the 2nd polygonal region 420 is pasted in advance.
Storage part 201 also can store the 1st sticking area information the 251, the 2nd sticking area information the 252, the 1st texture image the 310, the 2nd texture image 320 in other the storer such as external memory storage 106 into.
202 pairs the 1st sticking area information 251 of update portion and the 2nd sticking area information 252 are upgraded; So that the 1st polygonal region 410 and the 2nd polygonal region 420 regulation separately on one side; Consistent at certain time point; And make the vertex position beyond this regulation end points on one side, in the 1st polygonal region 410,, in the 2nd polygonal region 420, swing respectively and change shape with the 2nd cycle with the 1st cycle.CPU101, RAM103, image processing part 108 are through interoperation, as update portion 202 performance functions.
In the 1st polygonal region 410 and in the 2nd polygonal region 420, definition has local coordinate system (U-V coordinate system) respectively.
Fig. 5 A, Fig. 5 B, Fig. 5 C are the figure of the appearance that changes of shape of expression the 1st polygonal region 410.
Fig. 6 A, Fig. 6 B, Fig. 6 C are the figure of the appearance that changes of shape of expression the 2nd polygonal region 420.In order to understand the present invention easily, the shape set that illustrates the 1st polygonal region 410 under the state (original state) before the change shape is rectangular situation.
Wherein, Among Fig. 5 A～Fig. 5 C, Fig. 6 A～Fig. 6 C; In the 1st polygonal region 410, pasted the 1st texture image 310; In the 2nd polygonal region 420, pasted the 2nd texture image 320,, will in the explanation of the structure that generates display part 203, be elaborated about the processing that the 1st polygonal region 410 and the 2nd polygonal region 420 are pasted the 1st texture image 310 and the 2nd texture image 320 respectively.
CPU101 is through having used the affine conversion of the affine matrix of stipulating, with the figure deformation of expression the 1st polygonal region 410.Fig. 5 A has represented the 1st polygonal region 410 under the state (original state) before the affine conversion.Fig. 5 B, Fig. 5 C have represented the 1st polygonal region 410 after the affine conversion.
CPU101 will connect the line segment on adjacent 2 summits 511,512 of the 1st polygonal region 410, as above-mentioned regulation (below be called " fixed edge ") 510 on one side.Fixed edge 510 is constant at affine conversion front and back position.
In following explanation, will, be expressed as " L " to the parameter that the size of the axial amount of movement of U is represented to the opposite side (line segment that connects 2 summits 513,514) of fixed edge 510.To be expressed as " θ " to by the one side of the line segment performance that connects summit 512,513 and the parameter represented by the size of the angle of one side inclination of the line segment performance that is connected summit 511,514.
Equally, will, be expressed as " M " to the parameter that the size of the axial amount of movement of U is represented to the opposite side (line segment that connects 2 summits 613,614) of fixed edge 610.To be expressed as " φ " to by the one side of the line segment performance that connects summit 612,613 and the parameter represented by the size of the angle of one side inclination of the line segment performance that is connected summit 611,614.
After the generation display part 203 stated the 1st texture image 310 is pasted the 1st polygonal region 410; And when the 2nd texture image 320 is pasted the 2nd polygonal region 420, preferably constitute the zone of opacity 515 on the fixed edge 510 in all pixel datas of the 1st texture image 310 the position, with all pixel datas that constitute the 2nd texture image 320 in fixed edge 610 on the position of zone of opacity 615 identical.
For example; Before and after the distortion of carrying out the 1st polygonal region 410 and the 2nd polygonal region 420 in update portion 202; The leaf root part of the leaf of drawing in the 1st texture image 310 all the time with the 2nd texture image 320 in the consistent mode of leaf root part of the leaf drawn, generate the 1st texture image 310 and the 2nd texture image 320.Like this, can show the rocking action of leaf more naturally.
For example; CPU101 is through such shown in Fig. 5 B; Under the state that the position and the direction of fixed edge 510 are fixed; The opposite side (line segment that connects 2 summits 513,514) that makes fixed edge 510 is to the parallel displacement L of the negative direction of U axle, thus the 1st polygonal region 410 is deformed into parallelogram from rectangle.In other words, one side CPU101 is according to the mode by the line segment one side of representing and the tilt angle theta represented by the line segment that is connected summit 511,514 that connect summit 512,513, with 410 distortion of the 1st polygonal region.
Distance L is variable in the scope of 0≤L≤LA.Angle θ is variable in the scope of 0≤θ≤θ A.Distortion shown in this figure is commonly referred to as cuts off distortion.
For example, CPU101 is through such shown in Fig. 5 C, and under the state that fixed edge 510 is fixing, the opposite side that makes fixed edge 510 is to the parallel displacement L of the positive dirction of U axle, thus the 1st polygonal region 410 is deformed into parallelogram from rectangle.In other words, one side CPU101 is according to the mode by the line segment one side of representing and the tilt angle theta represented by the line segment that is connected summit 511,514 that connect summit 512,513, with 410 distortion of the 1st polygonal region.
Distance L is variable in the scope of 0≤L≤LB.Angle θ is variable in the scope of 0≤θ≤θ B.
For example, CPU101 also can make up the distortion shown in the distortion shown in Fig. 5 B and Fig. 5 C.That is, CPU101 makes the opposite side of fixed edge 510, along with the process of time, according to the maximum parallel mobile LA of the negative direction of U axle, to the mode oscillating motion of the maximum parallel mobile LB of positive dirction of U axle.
In other words; CPU101 is according to line segment one side of representing and one side of being represented by the line segment that is connected summit 511,514 by connection summit 512,513; To the negative direction maximum inclination θ of U axle A, the mode to the positive dirction maximum inclination θ of U axle B makes its oscillating motion.Hunting period separately can be identical, also can be different.
CPU101 uses the position of the 1st polygonal region 410 after changing and the information that shape is represented, upgrades the 1st sticking area information 251.
Equally, CPU101 is through having used the affine conversion of the affine matrix of stipulating, with the figure deformation of expression the 2nd polygonal region 420.Fig. 6 A has represented the 2nd polygonal region 420 under the state (original state) before the affine conversion.Fig. 6 B and Fig. 6 C represent the 2nd polygonal region 420 after the affine conversion.
CPU101 will connect the line segment on adjacent 2 summits 611,612 of the 2nd polygonal region 420, as fixed edge 610.Fixed edge 610 is same with fixed edge 510, and is constant at affine conversion front and back position.
For example; CPU101 is through such shown in Fig. 6 B; Under the state that the position of fixed edge 610 and direction is fixing, the opposite side that makes fixed edge 610 is to the parallel displacement M of the negative direction of U axle, thus the 2nd polygonal region 420 is deformed into parallelogram from rectangle.In other words, one side CPU101 is according to the mode by the line segment one side represented and angles of inclination φ that is represented by the line segment that is connected summit 611,614 that connect summit 612,613, with 420 distortion of the 2nd polygonal region.
Variable in the scope of 0≤M≤MA apart from M.Angle φ is variable in the scope of 0≤φ≤φ A.
For example, CPU101 is through such shown in Fig. 6 C, and under the state that fixed edge 610 is fixing, the opposite side that makes fixed edge 610 is to the parallel displacement M of the positive dirction of U axle, thus the 2nd polygonal region 420 is deformed into parallelogram from rectangle.In other words, one side CPU101 is according to the mode by the line segment one side represented and angles of inclination φ that is represented by the line segment that is connected summit 611,614 that connect summit 612,613, with 420 distortion of the 2nd polygonal region.
Distance L is variable in the scope of 0≤M≤MB.Angle φ is variable in the scope of 0≤φ≤φ B.
For example, CPU101 also can make up the distortion shown in the distortion shown in Fig. 6 B and Fig. 6 C.That is, CPU101 makes the opposite side of fixed edge 610, and along with the process of time, according to the maximum parallel mobile MA of the negative direction of U axle, the mode to the maximum parallel mobile MB of positive dirction of U axle makes its oscillating motion.In other words; CPU101 is according to line segment one side of representing and one side of being represented by the line segment that is connected summit 611,614 by connection summit 612,613; To the negative direction maximum inclination φ of U axle A, the mode to the positive dirction maximum inclination φ of U axle B makes its oscillating motion.Hunting period separately can be identical, also can be different.
CPU101 uses the position of the 2nd polygonal region 420 after changing and the information that shape is represented, upgrades the 2nd sticking area information 252.
The 1st polygonal region 410 and the 2nd polygonal region 420 regulation separately is meant that the fixed edge 510 of the 1st polygonal region 410 is present on the identical straight line at certain time point with the fixed edge 610 of the 2nd polygonal region 420 jointly in that certain time point is consistent on one side.Under the typical situation, " certain time point " is meant the original state before the affine conversion.The fixed edge 10 of the 1st polygonal region 410 and the fixed edge 610 of the 2nd polygonal region 420 also can be present on the same straight line all the time.
Wherein, the image that CPU101 waves according to the hope performance from polygonal each limit of representing the 1st polygonal region 410 and the 2nd polygonal region 420, is suitably selected 1 respectively as fixed edge 510,610.For example, if hope the appearance that leaf that performance is hung down from branch waves with the wind, then at direction setting fixed edge 510,610 along the branch of the leaf of having grown.For example, wave mobile appearance along with flowing of seawater, then at direction setting fixed edge 510,610 along the seabed of the sea grass that grown if hope the sea grass such as sea-tangle or marine alga of the marine growth of performance.
Through setting fixed edge 510,610 like this, can more clearly show and be not that object is moving around, but the appearance that object waves under the state that certain part is fixed.
The shape of the 1st polygonal region 410 and the 2nd polygonal region 420 is not limited to rectangle or parallelogram.For example, also can be shown in Fig. 7 A such, be arbitrary quadrilateral with the shape set of the 1st polygonal region 410 before and after the distortion with summit 511～514.CPU101 also can be according to other summits 513,514 beyond the summit 511,512 at fixed edge 510 two ends, and the mode of reciprocally swinging on the track 701,702 of regulation is out of shape the 1st polygonal region 410 respectively.The hunting period on preferred summit 513 is identical with the hunting period on summit 514.
In addition, for example also can be shown in Fig. 7 B such, be arbitrary triangle with the shape set of the 1st polygonal region 410 before and after the distortion with summit 511～513.CPU101 also can be according to the mode of other summits 513 reciprocally swinging on the track 703 of regulation beyond the summit 511,512 at fixed edge 510 two ends, with 410 distortion of the 1st polygonal region.
Equally, the shape of the 2nd polygonal region 420 also can be set at the arbitrary quadrilateral with summit 611～614 or have the arbitrary triangle on summit 611～613.That is, in Fig. 7 A, Fig. 7 B, as long as summit 511～514 is replaced to summit 611～614, fixed edge 510 is replaced to fixed edge 610.
Then; Generate the 1st sticking area information 251 that display part 203 generates according to storage in the storage part 201; On the 1st polygonal region 410, pasted the 1st texture image 310; According to the 2nd sticking area information 252 of storage in the storage part 201, on the 2nd polygonal region 420, pasted the image of the 2nd texture image 320, and the image that generates has been shown on the display.CPU101, RAM103, image processing part 108 interoperations are as generating display part 203 performance functions.
Particularly; Shape at the 1st polygonal region 410 is under the tetragonal situation; Such shown in Fig. 8 A; CPU101 controls image processing part 108, the summit 311 through making the 1st texture image 310 and the summit of the 1st polygonal region 410 be 511 corresponding, make summit 312 and summit 512 corresponding, make summit 313 and summit 513 corresponding, make summit 314 corresponding with summit 514, the 1st texture image 310 is pasted on the 1st polygonal region 410.
Equally; Shape at the 2nd polygonal region 420 is under the tetragonal situation; The summit 321 that CPU101 makes the 2nd texture image 320 and the summit of the 2nd polygonal region 420 be 611 corresponding, make summit 322 and summit 612 corresponding, make summit 323 and summit 613 corresponding, make summit 324 corresponding with summit 614, the 2nd texture image 320 is pasted on the 2nd polygonal region 420.
In following explanation, CPU101 is controlled image processing part 108, generate the 1st texture image 310 and the 2nd texture image 320 are pasted the treatment of picture on the 1st polygonal region 410 and the 2nd polygonal region 420 respectively, be called image and generate processing.
Shape at the 1st polygonal region 410 is under the leg-of-mutton situation; Such shown in Fig. 8 B; CPU101 controls image processing part 108; The summit 311 that makes the 1st texture image 310 and the summit of the 1st polygonal region 410 be 511 corresponding, make summit 312 and summit 512 corresponding, make summit 313 and summit 314 all corresponding with summit 513, the 1st texture image 310 is pasted on the 1st polygonal region 410.
Equally; Shape at the 2nd polygonal region 420 is under the leg-of-mutton situation; The summit 321 that CPU101 makes the 2nd texture image 320 and the summit of the 2nd polygonal region 420 be 611 corresponding, make summit 322 and summit 612 corresponding, make summit 323 and summit 324 all corresponding with summit 613, the 2nd texture image 320 is pasted on the 2nd polygonal region 420.
Fig. 9 A～Fig. 9 C is under the shape of the 1st polygonal region 410 before making distortion and the position, shape of the 2nd polygonal region 420 before the distortion, the big or small identical situation, the example that CPU101 has pasted the 1st texture image 310, the 2nd polygonal region 420 pasted the image of the 2nd texture image 320 the 1st polygonal region 410.Before Fig. 9 A representes the distortion of the 1st polygonal region 410 and the 2nd polygonal region 420, after Fig. 9 B, Fig. 9 C represent distortion.
CPU101 is according to fixing the position and the direction of the fixed edge 510 of the 1st polygonal region 410, and with the 1st hunting period of regulation, the mode of unit interval deformation angle θ is with 410 distortion of the 1st polygonal region.And; CPU101 is according to the position and the direction of the fixed edge 610 of the 2nd polygonal region 420 are fixed; With the 2nd hunting period of regulation, to the mode of the direction unit interval deformation angle φ opposite, with 420 distortion of the 2nd polygonal region with the deformation direction of the 1st polygonal region 410.
If hypothesis is identical with being made as the 1st hunting period (hunting period of the 1st polygonal region 410) and the 2nd hunting period (hunting period of the 2nd polygonal region 420), the image that then generates changes according to the order of Fig. 9 A, Fig. 9 B, Fig. 9 A, Fig. 9 C.Through CPU101 repeatedly carries out image generate to handle, can generate as leaf of in the 1st texture image 310, drawing and the leaf in the 2nd texture image 320, drawn alternately such each other, the wiggly animated image of leaf.
Figure 10 A and Figure 10 B are with the 1st texture image 310 shown in Fig. 3 A and the 2nd texture image 320 shown in Fig. 3 B, and the 1st polygonal region 410 that pastes Fig. 4 respectively is with the 2nd polygonal region 420 and an example of the image of formation.Though in order to understand the present invention easily, represented the edge of the 1st polygonal region 410 and the edge of the 2nd polygonal region 420 with solid line, these edges can not be shown in display.
Shown in Figure 10 A and Figure 10 B; When in picture 400, having a plurality of the 1st polygonal regions 410 (and/or the 2nd polygonal region 420); CPU101 implements affine conversion etc. to each the 1st polygonal region 410 (and/or the 2nd polygonal region 420); Make its change in shape, paste the 1st texture image 310 (and/or the 2nd texture image 320).The deformation method of each the 1st polygonal region 410 (and/or the 2nd polygonal region 420) can be identical, also can be different.
For example; If in picture 400, set a plurality of the 1st polygonal regions 410 (and/or the 2nd polygonal region 420); And use identical affine matrix to make its distortion to the 1st all polygonal region 410 (and/or the 2nd polygonal region 420); Paste the 1st texture image 310 (and/or the 2nd texture image 320), then can generate the image that appearance that the pattern drawn in the 1st texture image 310 (and/or the 2nd texture image 320) is waved about up and down etc. is simultaneously represented identically.
Generally in computerized mapping (CG) field; Use the application software that is called as light and shade maker (shader) to play up mostly; But according to the present invention, only need carry out the deformation process of the figure in the smaller U-V space of calculated load, can show the action of waving.
Below, in conjunction with the process flow diagram of Figure 11, the performed image of above-mentioned each one of this embodiment is generated processing describe.
At first, CPU101 from RAM103, read expression the 1st polygonal region 410 position and shape the 1st sticking area information 251 and represent the position of the 2nd polygonal region 420 and the 2nd sticking area information 252 (step S1101) of shape.
CPU101 uses the affine matrix AM1 of regulation, and the figure (polygon) of representing the 1st polygonal region 410 is carried out affine conversion.And CPU101 uses the affine matrix AM2 of regulation, and the figure of representing the 2nd polygonal region 420 is carried out affine conversion (step S1102).
If will be made as based on the distortion of affine matrix AM1 with based on the opposite direction of the distortion of affine matrix AM2, then can more clearly show the action of waving.For example, such shown in Fig. 9 B, Fig. 9 C, CPU101 makes the 1st polygonal region 410 deformation angle θ, makes the 2nd polygonal region 420 to the direction deformation angle φ opposite with angle θ.Wherein, the direction of distortion is arbitrarily.The size of the size of angle θ and angle φ can be identical, also can be different.
For example, when in the Virtual Space, supposing have wind out-of-date, if wind is more weak, then the deformation direction with the 1st polygonal region 410 and the 2nd polygonal region 420 is made as on the contrary.On the other hand, if wind is more intense, then the deformation direction with the 1st polygonal region 410 and the 2nd polygonal region 420 is made as identical.Like this, can make the rich variation of the action of waving, so that when weak wind, leaf slowly waves, during high wind, leaf is swing strongly with the wind.
CPU101 controls image processing part 108, pastes the 1st texture image 310 to the 1st polygonal region 410, pastes the 2nd texture image 320 (step S1103) to the 2nd polygonal region 420.The processing of this step is commonly referred to as plays up.
Then; CPU101 is according to the position and the shape of the 1st polygonal region 410 that in step S1102, has been out of shape; Upgrade the 1st sticking area information 251; And, upgrade the 2nd sticking area information 252 (step S1104) according to the position and the shape of the 2nd polygonal region 420 that in same step S1102, has been out of shape.
CPU101 controls image processing part 108, and the image that will in step S1103, generate is shown on the display.
Carry out this image repeatedly and generate and handle through for example interrupting, can generate the animation that the rocking action to the object in the Virtual Space shows by each vertical synchronization.
Generally speaking, in image, show scarcely easily the such transparent air of wind move and water in the moving of transparent water.Therefore,, make the figure deformation of the stickup object of texture, paste texture, then can when alleviating image processing load, can show the action of waving simply according to the figure after the distortion if as the present invention.
In this embodiment, in picture 400, set 2 kinds of polygonal regions, but also can set polygonal region more than 3 kinds, and made each polygonal region distortion by CPU101.
(embodiment 2)
Then, other embodiments of the present invention are described.In the above-described embodiment, separately used 2 texture images 310,320, but also can use a shared texture image to paste the 1st polygonal region 410 and the 2nd polygonal region 420.In addition, also can separately use the texture image more than 3.
For example, such shown in Figure 12 A as the most simple existing technique of expression when generation is contained in the image of the pudding on the plate, draw as long as on 1 polygonal region 1201, paste 1 texture image 1202.On the other hand, in the technique of expression that caricature etc. is adopted, a plurality of patterns of use are arranged, 1 object of performance waves or the method for mobile appearance as image retention.For example, several through an identical pudding is specially drawn shown in Figure 12 B when drawing the appearance of the soft rustle vibration of pudding, and draw image retention, show the appearance of vibration.If application the present invention, then can as through employed technique of expression in caricature etc. draw that kind, represent the appearance of object (pudding) vibration.
That is, shown in Figure 12 C, under original state, the 1st polygonal region 410 and the 2nd polygonal region 420 of same position and same shape is set in the picture 400.Be prepared in advance to the shared texture image 1202 of the 1st polygonal region 410 and 420 stickups of the 2nd polygonal region.
Then, shown in Figure 12 D, CPU101 with the 1st polygonal region 410 with specified period TI deformation angle θ.Equally, CPU101 with the 2nd polygonal region 420 with identical cycle T 1 to opposite direction deformation angle θ.In other words, the 1st polygonal region 410 after the distortion and the 2nd polygonal region 420 shape separately after the distortion, straight line 1203 constitutes the relation of lines symmetry relatively.
Then, CPU101 pastes texture images 1202 to the 1st polygonal region 410 after being out of shape and the 2nd polygonal region 420.
CPU101 carries out that kind shown in figure 13 repeatedly and changes along with the process of time makes angle θ, the processing that the 1st polygonal region 410 and the 2nd polygonal region 420 are out of shape.When that kind shown in figure 13 makes angle θ with cycle T 1 swing of regulation, the appearance of can more understandable ground represented object waving.
(embodiment 3)
Below, other embodiments of the present invention are described.CPU101 also can make the 1st polygonal region 410 and 420 distortion of the 2nd polygonal region on the direction vertical with fixed edge 510,610.
For example, such shown in Figure 14 A, 1st polygonal region (or 2nd polygonal region) 1400 of CPU101 before to the distortion with summit 1401～1404 on the basis of having fixed fixed edge 1405, makes its distortion according to the mode of tilt angle theta.At this moment, it is constant to establish the length on each limit.So the height of the 1st polygonal region after the distortion (or the 2nd polygonal region) 1410 is than the low Δ L of the 1st polygonal region (or the 2nd polygonal region) 1400 before the distortion.
Figure 14 B is that expression CPU101 controls image processing part 108, and the 1st polygonal region 1410 after the distortion is pasted the texture image of regulation, the figure of the image that the 2nd polygonal region 1420 same regulation texture images of stickup after the distortion are formed.Because through so yet distortion on the direction vertical with fixed edge 1405, texture image can not expanded (length of tree prolongs) to transverse direction, so can show the appearance of waving more naturally.
Need to prove; When the 1st polygonal region 1410 and the 2nd polygonal region 1420 after the distortion are pasted texture image respectively; If make the invariant position of the zone of opacity 1406 on the fixed edge 1405 in the pixel data that constitutes texture image, then can show the appearance of waving more naturally.
(embodiment 4)
Below, other embodiments of the present invention are described.The difference of this embodiment and above-mentioned embodiment is, setting the 1st polygonal region 410 picture 400 in and do not set the 2nd polygonal region 420.
Figure 15 A, Figure 15 B, Figure 15 C are the figure of the appearance that changes of shape of expression the 1st polygonal region 410.In being pasted on the 1st texture image 310 of the 1st polygonal region 410, draw the pattern of a plurality of objects that are hopeful to show rocking action in advance.For example, in the 1st texture image 310, draw the pattern of a plurality of leaves.
Figure 15 A representes the appearance of having pasted the 1st texture image 310 on the 1st polygonal region 410 of CPU101 before shape conversion.For example, before shape conversion, the shape of the 1st polygonal region 410 is made as rectangle, the length on the V direction (highly) is made as L1.
CPU101 as fixed edge 510, makes 410 distortion of the 1st polygonal region with one side of the 1st polygonal region 410.For example, CPU101 shown in Figure 15 B, with the 1st polygonal region 410 to the negative direction tilt angle theta A of U axle and be deformed into parallelogram.Perhaps, such shown in Figure 15 C, CPU101 is deformed into parallelogram with the 1st polygonal region 410 to the positive dirction tilt angle theta B of U axle.Then, CPU101 pastes the 1st texture image 310 on the 1st polygonal region 410 after the distortion.
CPU101 that kind shown in figure 13 is along with the angle θ that changes inclination through coming of time.That is, CPU101 with cycle T 1 reciprocating mode, changes angle θ according in the scope of θ MIN≤θ≤θ MAX.The 1st polygonal region 410 becomes the shape shown in Figure 15 B from the change in shape shown in Figure 15 A; And then become the shape shown in Figure 15 A from the change in shape shown in Figure 15 B; Become the shape shown in Figure 15 C from the change in shape shown in Figure 15 A then, further become the shape shown in Figure 15 A from the change in shape shown in Figure 15 C.Through carrying out such variation repeatedly, the appearance of coming represented object (being leaf under this situation) to wave.
In addition, also can be with above-mentioned each embodiment combination, CPU101 not only makes angle θ change, and makes the height change of the 1st polygonal region 410.
