Compare more contents.When applying the viewable portion that 102 update application image 110 using vision area 114, composograph 112
Can update or produce visually smoother transition outward appearance more quickly.
Application image 110 logically can be divided into or be divided into image sheet 116 by application 102.In image sheet 116
Each can identify the respective regions of application image 110.In whole application image 110, image sheet 116 is in size and shape
On can be consistent.Alternatively, in whole application image 110, the size and shape of image sheet 116 can change.?
In different examples, the size and shape of image sheet 116 can be different.
Image sheet 116 can be represented in corresponding image sheet relief area 118.For example, it is possible to be individually appointed as
The image sheet 116 being individually appointed as T1 to T4 in FIG is represented in the image sheet relief area 118 of A1 to A4.Image sheet delays
Rush area 118 to may be embodied in application relief area 104.
Which in vision area 114 overlapping image piece 116 be composition manager 108 can determine.Overlap or folded with vision area 114
Each of image sheet 116 of lid (intersect) can at least include the part 120 of the viewable portion of application image 110.
On the contrary, the image sheet 116 that vision area 114 does not overlap may not comprise any viewable portion 120 of application image 110.
Composition manager 108 can carry out dual to the image sheet 116 that vision area 114 overlaps rather than residual graph photo 116
Buffering.Front buffer area 122 can include representing the image sheet relief area 118 of the overlapping image sheet 116 (T3 and T4) of vision area 114
(A3 and A4).Therefore, the image sheet relief area 118 (A3 and A4) in front buffer area 122 includes the buffered of application image 110
Viewable portion 124.On the contrary, back buffer area 126 can include representing the image sheet 116 (T1 and T2) that vision area 114 does not overlap
Image sheet relief area 118 (A1 and A2).Additionally, back buffer area 126 can include and the figure being in front buffer area 122
Photo relief area 118 (A3 and A4) is corresponding and image sheet relief area 118 that represent the image sheet 116 being overlapped by vision area 114
(B3 and B4).
When generating composograph 112, composition manager 108 can be delayed from the image sheet being in front buffer area 122
Rush the buffered viewable portion 124 extracting application image 110 in area 118 (A3 and A4).Buffered viewable portion 124 is permissible
There is the frame n of application image 110.Application 102 can be in the image sheet relief area 118 in back buffer area 126 by modification
(A1, A2, B3 and B4) is assuming the frame n+1 of the application image 110 in back buffer area 126.
When generation is replaced in relief area, the image sheet being in back buffer area 126 can be buffered by composition manager 108
The content of the subset in area 118 copies to front buffer area 122.The subset of image sheet relief area 118 can be and be in preposition delaying
Rush the corresponding image sheet relief area 118 (B3 and B4) in image sheet relief area 118 (A3 and A4) in area 122.Composition manager
108 can skip the image sheet relief area 118 (A1 and A2) of the image sheet 116 (T1 and T2) that would indicate that vision area 114 does not overlap again
Make front buffer area 122.
As the content of the subset of image sheet relief area 118 is multiple from back buffer area 126 when replacing generation when relief area
Make replacement or the interpolation in front buffer area 122, it is slow with preposition that composition manager 108 can change image sheet relief area 118
Rush the association between area 122 and back buffer area 126.Composition manager 108 can follow the tracks of image sheet buffering in data structure
Which in area 118 be associated with front buffer area 122 and image sheet relief area 118 in which and back buffer
Area 126 is associated.Associating between image sheet relief area 118 and front buffer area 122 and back buffer area 126 indicates image sheet
Which in relief area 118 is included in each of front buffer area 122 and back buffer area 126.When relief area is replaced
When changing raw, the subset (B3 and B4) of image sheet relief area 118 can be released by composition manager 108 with back buffer area 126
Association, and the subset (B3 and B4) of image sheet relief area 118 is associated with front buffer area 122.Therefore, composition manager
The image sheet relief area 118 (A3 and A4) being initially associated with front buffer area 122 can be changed into and back buffer area by 108
126 are associated.In other words, composition manager 108 can be replaced in response to relief area, by image sheet relief area 118 with preposition
The first set that relief area 122 is associated and the second set being associated with back buffer area 126 of image sheet relief area 118 are entered
Row exchanges, and wherein, the image sheet relief area 118 being exchanged represents that the overlapping image sheet 116 of vision area 114 does not indicate that vision area 114
The image sheet 116 not overlapped.
When composition manager 108 by the image sheet relief area 118 being associated with front buffer area 122 and with back buffer area
When 126 associated corresponding image sheet relief areas 118 swap, the image sheet being switched in back buffer area 126 delays
Rush the frame that area 118 can represent older, for example, frame n.The image sheet relief area 118 being switched in front buffer area 126 is permissible
Represent frame n+1.After relief area exchanges, application 102 can assume the 3rd frame, for example, frame n+2 in back buffer area 126.
When vision area 114 is mobile and overlaps with new image sheet in image sheet 116, composition manager 108 can be to new
Overlapping image sheet 116 carries out double buffering.On the contrary, when vision area 114 is mobile and no longer overlapping with one of image sheet 116 when,
Composition manager 108 can stop carrying out double buffering to the image sheet 116 previously overlapping.
Therefore, when vision area 114 is mobile, composition manager 108 can adjust which in image sheet relief area 118 at
The image sheet that image sheet relief area 118 in front buffer area 122 so that in front buffer area 122 is overlapped with vision area 114
116 is corresponding.Similarly, when vision area 114 is mobile, which in image sheet relief area 118 be composition manager 108 can adjust
It is in back buffer area 126.
When vision area 114 is mobile and overlaps with the image sheet 116 newly overlapping, in back buffer area 126 with newly overlap
The corresponding image sheet relief area 118 of image sheet 116 may be embodied in front buffer area 122.Do not need be in again completely
Now it is added to the image sheet relief area 118 in front buffer area, this is because application 102 may be in back buffer area 126
Present image sheet relief area 118.
In some systems, can dynamically distribute with the movement of vision area 114 and discharge image sheet relief area 118.
For example, if vision area 114 mobile and with the image sheet 116 shown in Fig. 1 in four image sheets (T1 to T4) rather than figure
Two image sheets (T3 and T4) in photo 116 overlap, then composition manager 108 can dynamically distribute two image sheet bufferings
Area 118 (B1 and B2, it is not shown in FIG).Then, front buffer area 122 can include four in image sheet relief area 118
Individual image sheet relief area (A1 to A4), and back buffer area 126 can include four corresponding image sheet relief area 118 (B1
To B4).
As the replacement of dynamically distributes image sheet relief area 118, image sheet relief area 118 can be distributed in advance.For example, exist
After the initialization of application 102 request, composition manager 108 can distribute enough image sheet relief areas 118, with rearmounted
Application image 110 is fully represented in relief area 126 and front buffer area 122.Composition manager 108 can dynamically be divided in advance
The image sheet relief area 118 joined is associated with front buffer area 122 and back buffer area 126.
Application 102 and composition manager 108 can have the features different from described feature.In a system,
Application image 110 can be divided or be divided into image sheet 116 by composition manager 108 (rather than application 102).Application 102 can
To call API (application programming interface) to indicate the size of application image 110 to composition manager 108.As response, composite tube
Application image 110 can be divided into image sheet 116 by reason device 108, and distributes corresponding image sheet relief area 118.Another
In individual system, application 102 (rather than composition manager 108) can be to the image sheet 116 being overlapped by vision area 114 rather than residue
Image sheet 116 carries out double buffering.In another system, except application 102 and composition manager 108 in addition to one or many
Individual assembly can execute the described function of application 102 and composition manager 108.
Composition manager 108 can assume composite diagram according to the viewable portion of the application image 110 being identified by vision area 114
