With reference to the flow diagram of the image rendering method provided in an embodiment of the present invention shown in Fig. 3, it is described in detail
The image rendering method of the present invention, including：
Step S300：The special efficacy object that need to currently render is read, is preserved according to being sliced when the special efficacy object registered in advance
Display data, determine that present frame and next frame need the regional area rendered；
Specifically, a special efficacy object can correspond to multiple image data, that is to say, that a special efficacy object is by multiframe figure
It is presented as combination, when system, which receives special efficacy, to be executed instruction, the special efficacy object rendered can will be needed to be put into special efficacy queue
In manager, the special efficacy queue in the special efficacy queue management device of the embodiment of the present invention follows the logic of first in first out；So system
The special efficacy object that need to currently render can be read from the special efficacy queue management, and according to the special efficacy object when being registered pair
It should carry out the display data of slice preservation, it may be determined that the special efficacy object present frame and next frame need the partial zones rendered
Domain, that is, the corresponding display area of display data that the slice of present frame and next frame preserves is present frame and next frame
Need the regional area rendered.
It should be noted that multiple first kind display datas or multiple second can be sliced out in a frame image data
Type display data.Wherein, it includes the first kind display data and second class which, which needs the regional area rendered,
Type display data, the first kind display data is less than the Second Type display data in each embodiment of the present invention, that is,
It says, which is less than the corresponding display area of Second Type display data.
It should also be noted that, can also be included in before step S300 when will change special efficacy object registration to graphics engine,
Effective display data in each frame of special efficacy object is calculated, and the display data is sliced；By the first kind after slice
Type display data is stored in CpuRes, and the Second Type display data after slice is stored in GpuRes.
Specifically, when a special efficacy object is registered to graphics engine, it can be assigned to a sub-line journey pre-execution
Once, then hardware-accelerated wafer breaker can be particularly shown data slicer to its each frame；In each embodiment of the present invention
Slice includes but not limited to carry out triangle slice by triangular image calculating method, as Fig. 4 shows that the embodiment of the present invention provides
Triangle slice preserve principle schematic, list two field pictures data and be sliced, triangular graph can be passed through first
As calculating method calculates effective display data (being particularly shown data) in each frame of special efficacy object, and to the display data into
Row triangle is sliced；Then the first kind display data after slice is stored in CpuRes by pattern analysis, will be sliced
Second Type display data afterwards is stored in GpuRes；Again in detail, the triangle less than the first predetermined threshold value can be cut
The display data of piece is stored in CpuRes, and the display data that will be greater than the triangle slice of the second predetermined threshold value is stored in
In GpuRes, that is to say, that the first kind display data should be used as less than the triangle slice of the first predetermined threshold value, this is more than
The display data of the triangle slice of second predetermined threshold value as the Second Type display data, and the first predetermined threshold value be less than or
Equal to second predetermined threshold value, so that the corresponding display area of first kind display data is shown less than the Second Type
The corresponding display area of data.
In addition, the embodiment of the present invention can also will need the region (it is corresponding to be particularly shown data) wiped to be stored in wiping
Except in memory ClearRes, then, system, can also be according to the ClearRes after reading the special efficacy object that need to currently render

Specifically, can with the principle schematic of the code logic precomputation provided in an embodiment of the present invention shown in reference chart 5,
In conjunction with the frame diagram of Fig. 1, when rendering starts operation, runway model thread is started to work, which can be in each CPU free time
When start the rendering of next frame, the runway of each frame all includes executing code logic precomputation (Code Execution) and executing
Double accelerated passages, which render, calculates (Accelerated Renderding), and precomputation renderer is called in the code logic precomputation
After needing the regional area rendered to be wiped in painting canvas present frame and next frame, corresponding to present frame in CpuRes first
Type display data carries out precomputation rendering, obtains precomputation figure；
It should be noted that after obtaining precomputation figure, which can also be by hardware-accelerated wafer breaker
CpuRes in the corresponding first kind display data of next frame that preserves be defeated by CPU in advance and calculated.
Step S304：Present frame in graphics processor memory GpuRes is corresponded to by preset underlying graphics library renderer
Second Type display data rendered, and merge rendering with the precomputation figure, obtain present frame and completely show
Diagram picture.
Specifically, the principle calculated can be rendered with double accelerated passages provided in an embodiment of the present invention shown in reference chart 6 to show
It is intended to, when executing double accelerated passages rendering calculating, can first locks current painting canvas, it is ensured that user not can be appreciated that showing for splashette
As, then it will need in triangle (by taking triangle the is sliced as an example) digital independent to runway model rendered using GPU, i.e., it will figure
The corresponding Second Type display data of present frame is read in runway model in shape processor memory GpuRes, then using default
Underlying graphics library renderer the corresponding Second Type display data of present frame in the GpuRes is rendered, while can will
Code logic precomputation is defeated by the CpuRes memories (i.e. above-mentioned precomputation figure) that CPU execution is completed and is also defeated by the underlying graphics library
Renderer merges rendering, then can be finally obtained and added by binary channels (CPU＆GPU) mixing with matrixing graphical information again
The present frame of speed completely renders image, and unlocks the locking of this painting canvas, and user is allowed to can see this complete frame image.
By implement the embodiment of the present invention, first pass through precomputation renderer in the central processing unit memory CpuRes when
The corresponding first kind display data of previous frame carries out precomputation rendering, obtains precomputation figure, then pass through preset underlying graphics
Library renderer renders the corresponding Second Type display data of present frame in graphics processor memory GpuRes, and with it is described
Precomputation figure merges rendering, obtains present frame and completely shows image, realizes effective hybrid rending pattern, solves
Complicated special efficacy can reduce the operation pressure of CPU in the prior art, cause entirely to ask using interim card and the too fast technology of power consumption
Topic reduces mobile terminal fever, and brings more smooth special efficacy usage experience to user；The underlying graphics library can be than
The open graphic library (OpenGL, Open Graphics Library) of primary APP more bottoms, and encapsulated by skin mode
