Specific embodiment
The present invention will be described in more detail below with reference to accompanying drawings.Although showing the preferred embodiment of the present invention in attached drawing,
However, it is to be appreciated that may be realized in various forms the present invention and should not be limited by the embodiments set forth herein.On the contrary, providing
These embodiments are and the scope of the present disclosure completely can be communicated to ability to keep the disclosure more thorough and complete
The technical staff in domain.
Fig. 1 shows the multizone graphic plotting side according to an embodiment of the invention for intelligent operating system
Method.
The intelligent operating system environment of the present embodiment is Android, supports Open GL.Realize that step can generally divide
For two parts, difference java section and the part Native.Wherein, java section is realized by Java language program, is run on
Android virtual machine；The part Native passes through C/C++ language and realizes, runs on local server.
There are two main features for Open GL tool:
1, it is the software interface unrelated with hardware, can be transplanted between different platforms；
2, it can work in client/server system, that is, there is network function.
The multizone pattern drawing method for intelligent operating system of the present embodiment may comprise steps of:
1) multiple rendering threads that the end Java creates and multiple rendering engine examples that the end Native creates are bound.
Multiple rendering threads can be created simultaneously at the end Java, correspondingly, provide multiple rendering thread rings for the end Native
Border, and generate multiple context environmentals.Multiple render view examples are created at the end Java.
Render view is substantially the controller for the rendering at the end the Java control end Native.Render view class can be with
Including surface view (GLSurfaceView) example and texture view (GLTexureView) example, they are mentioned for the end Native
For rendering thread context.
The end Java generates the context environmental for rendering figure using the library Open GL by Open GL bank interface.
Open GL context environmental, i.e. GLContext, for storing all status informations of Open GL drawing.It is real
The default frame buffer (framebuffer) that rendering order is drawn is represented on border, GLContext is destroyed, and Open GL is not also multiple
In the presence of.
Multiple threads are created, that is, generate multiple context environmentals for Open GL, and a thread can only possess one
Context, correspondingly, a context environmental can only belong to a thread, cannot be shared simultaneously by different threads.
At the end Java, multiple rendering threads of creation are independently of the thread except main thread, this is to guarantee rendering
It can not be influenced by service logic thread.
At the end Native, rendering engine example is created based on multiple rendering thread contexts that the end Java is created.Meanwhile it is logical
Cross the rendering engine example initialization Open GL rendering contexts.
Initializing Open GL rendering contexts is mainly the important attribute that Open GL window is arranged, including pixel format eases up
Punch die formula, color digit and depth digit etc..
Open GL provides two kinds of color modes: RGB (RGBA) mode and color index mode.Own under RGBA mode
The definition of color is indicated with tri- values of RGB, sometimes also plus the Alpha value for indicating transparency.It is every under color index mode
The color of a pixel is indicated with some color index value in color index table.
Open GL can provide Double buffer and carry out drawing image.I.e. simultaneously, backstage caches the image in platform caching before display
Draw the 2nd width image.After completing from the background, the image in the caching of backstage is just shown.Foreground caching original at this time
Start to draw the 3rd width image, loop back and forth like this, to increase the output speed of image.
Correspond to one piece of region of screen by each rendering engine example that the end Native is created.
Rendering engine example is actually accomplished all figure rendering work, i.e., the initialization of completion Open GL rendering contexts,
Texture generation, changes in coordinates, color setting, figure rendering etc..
The rendering engine example initializes Open GL rendering contexts by Open GL bank interface.
Multiple rendering threads that the end Java creates and multiple rendering engine examples that the end Native creates are bound.?
In one illustrative embodiments, by by the multiple rendering engine example merging thread private data (TSD) come carry out with
The binding of the multiple rendering thread.
It is well known that under multi-thread environment, due to data space be it is shared, global variable is also all threads
It is common.One global variable, all threads can use it, change its value, therefore one of thread becomes the overall situation
The modification of amount will affect the access of another thread.Thus it is necessary to provide the overall situations that thread is privately owned in application programming
Variable uses the thread related data structures of address of variable of the same name and different.Surface seems it as global variable, and institute is wired
Journey can use it, and its value individually stores in each thread.Such data structure is referred to as thread
Private data.
Before distributing thread private data, need to create key (key) associated with thread private data, and be arranged
The key value of thread private data.Although the key of thread private data TSD be between the multiple threads it is shared, for every
A thread key value can be different.
At the end Native, rendering engine is externally singleton pattern, but when carrying out multizone graphic plotting, is actually needed
Wanting it is many cases.The many cases mould based on thread is realized by singleton pattern combination thread private data technology in this example
Formula, i.e. thread are different, and the example got by singleton pattern is also different, that is, the example got is corresponding with thread.
Specifically, multiple rendering threads can be created at the end Java, thread private data can be shared between multiple threads
The key of TSD, that is to say, that the access right of thread private data is shared in multiple rendering cross-threads.At the end Native, each
Rendering thread provided by rendering thread context in created rendering engine example respectively, by each rendering engine example merging with
In the TSD of its relevant rendering thread.That is, the key value of the thread private data in each rendering thread indicates it
Associated rendering engine.The binding for realizing rendering thread and rendering engine in this way, the management for rendering example are logical
The rendering thread bound therewith is crossed to complete, and it is also only visible to the thread bound therewith to render example.
The advantages of this mode is that the end Native is designed according to the design pattern of singleton, is eliminated to more
The management of a example.Traditional singleton design is current class externally only one example, is in general externally only connect by one
Mouth provides the example.And by introducing TSD technology, although still using the design pattern of singleton, i.e., externally also only provides one and connect
Mouthful example is obtained, but the example got for the same thread is always identical, and what different threads was got is not
Same example.I.e. in the thread, any one place all gets identical example by same interface.In this side
Under formula, in the same thread, the management to multiple examples is eliminated.
2) one or more figure rendering tasks that Java termination receives are submitted to respectively in different rendering threads, and
And one or more of figure rendering tasks are submitted to the end Native based on corresponding rendering thread.
When Java termination receives multiple figure rendering tasks, different figure rendering tasks is submitted to different renderings
In thread, and the end Native is submitted to based on respective rendering thread.
3) wash with watercolours with rendering thread binding corresponding to one or more of figure rendering tasks is obtained at the end Native
Engine instance is contaminated to carry out figure rendering.
Natvie end group obtains and the rendering thread respectively in the corresponding thread private data of the figure rendering task
The rendering engine example of binding carries out figure rendering.
Rendering engine example carries out figure rendering by Open GL order.
Figure rendering generally includes following several stages:
A) some geometric units such as geometric object, such as point, line, triangle are specified.
B) vertex processing operation.Data received by this stage are the attributive character on each vertex, and output is then
Transformed vertex data.
C) pel assembles.After the processing of vertex, whole attributes on vertex have all been determined, in this stage vertex meeting
Pel is assembled into according to pel rule.
D) pel is handled, and is mainly cut and is disappeared sunken.
E) rasterizing operates.The primitive data passed over by pel processing stage will be broken down into smaller at this stage
Unit and corresponding frame buffer zone each pixel, these units are referred to as piece member.One piece member may comprising the window left side,
The attributes such as depth, color, texture coordinate.
F) piece member is handled.It is managed including upper texture, i.e., corresponding color in texture memory is obtained by texture coordinate；Mist
Change, color is modified to current view point position by piece member distance；Color summarizes: by texture, the color of main definition, the face of atomization
Color, the color that the photostage of secondary color calculates gather.
G) operation of piece member one by one.Including pixel ownership, shearing, Alpha, stencil test, depth test, mixing
Deng these operations finally will affect it in the color value of frame buffer zone.
H) frame buffer operation.After figure rendering is completed, rendering engine is exchanged rendering result by Open GL interface
To display buffer, display is completed.Since each rendering engine example corresponds to one piece of region of screen, the knot of rendering
Fruit will directly display corresponding screen area.
4) rendering that the rendering result of one or more of figure rendering tasks is respectively displayed on and renders is drawn
It holds up in screen area corresponding to example.
Since different rendering engine examples corresponds to the different zones of screen, executed by different rendering engine examples
Figure rendering task rendering result can simultaneously be shown in the different zones of screen.It is thus achieved that intelligent operation
The graphic plotting of the multizone of system.
In the exemplary embodiment, which can further wrap
Include: after the completion of figure rendering task, rendering state is pulled back to the end Java by the end Native.
When the rendering engine at the end Native terminates to render, the rendering that rendering state can be returned to the end Java by rendering engine is regarded
Figure.I.e. the rendering of the notice end Java is completed or renders failure.
The advantages of multizone pattern drawing method for intelligent operating system of the present embodiment, is:
(1) figure rendering task is executed by the rendering engine example at the end Native, therefore is not limited by memory.
(2) rendering thread is not influenced independently of main thread by service logic thread；
(3) it can be rendered simultaneously in the multiple regions of screen simultaneously；
(4) many cases mode based on thread is realized by the singleton pattern of rendering engine+thread private data technology.
