Abstract
It is a kind of to realize that Android application obtains the method and system of OpenGL rendered pictures based on Hook technologies, by Hook technologies with the eglSwapBuffers function calls of customized my_eglSwapBuffers functions take over OpenGL application programs, it goes to replace the current frame buffer objects of OpenGL by creating customized frame buffer object, when OpenGL performs Rendering operations, rendering result can be output in customized frame buffer object, and then OpenGL rendered pictures are read out from customized frame buffer object associated Texture.This method has also taken over each function call by Hook technologies with custom function so that during figure is taken, application program it is expected to bind or change self-defined frame buffer object when binding or modification default frame cache object.
Description
Technical field
The present invention relates to the technologies that a kind of application of Android obtains OpenGL rendered pictures, specifically, are related to one kind and are based on
The method of Hook technologies, this method render function tune by Hook technologies with customized function take over OpenGL application programs
With, do not changing the original application layer code logic of the application program based on OpenGL and do not influence based on OpenGL should
With OpenGL rendered pictures are obtained in the case of programs render effect, belong to Android application field.
Background technology
In computer program design, Hook be it is a kind of by cutted function call or intercept component software between transfer
Message or event, to change or increase a kind of skill of the operating system either behavior of application program or other software component
Art.The code for handling cutted function calling, event or message is known as " Hook ".
OpenGL (Open Graphics Library) is to define one across programming language, cross-platform programming interface
The graphic package interface of the specialty of specification, it is one powerful, calls convenient for three-dimensional image (two-dimentional also can)
Underlying graphics storehouse.OpenGL ES (OpenGL for Embedded Systems) are the subsets of OpenGL 3-D graphic API, pin
The embedded devices such as mobile phone, PDA and game host are designed.
Android system supports 2D and 3D figures to render function using the standard interface of OpenGL ES, by load vertex,
The series of steps such as primitive information, texture, picture are rendered into frame buffer zone, and are eventually displayed on screen.
As Android system is becoming increasingly popular and mobile application constantly increases, increasingly come in Android system
More applications based on OpenGL needs to obtain the function of OpenGL rendered pictures.Existing acquisition OpenGL wash with watercolours in Android system
The method of dye picture is realized with reference to the source code of the engine based on OpenGL, however, there are some defects, head for this method
First, the OpenGL applications that source code is rendered for no OpenGL cannot then be realized with this method, furthermore, due to being based on OpenGL
Engine it is various, the mode of realization is also different, it is necessary to do special processing for different engines, and neither one leads to
Scheme can be realized, can so development difficulty be caused to increase, and the maintenance cost of code also can be very high.
The content of the invention
In view of problems of the prior art, it is an object of the invention to propose in a kind of Android system independent of
OpenGL application source codes obtain OpenGL wash with watercolours independent of the engine specifically based on OpenGL, general method
Contaminate picture.
