Class FullFrameRect
Hierarchy
java.lang.Object
- Package
- com.android.grafika.gles
Overview
This class essentially represents a viewport-sized sprite that will be rendered with a texture, usually from an external source like the camera or video decoder.Quick Jump
Constructors
FullFrameRect( Texture2dProgram program )
Prepares the object.
public FullFrameRect(Texture2dProgram program)
Constructor Parameters
- program
- The program to use. FullFrameRect takes ownership, and will release the program when no longer needed.
Methods
release( boolean doEglCleanup )
Releases resources.
This must be called with the appropriate EGL context current (i.e. the one that was current when the constructor was called). If we're about to destroy the EGL context, there's no value in having the caller make it current just to do this cleanup, so you can pass a flag that will tell this function to skip any EGL-context-specific cleanup.
public void release(boolean doEglCleanup)
Method Parameters
- doEglCleanup
getProgram()
Returns the program currently in use.
public com.android.grafika.gles.Texture2dProgram getProgram()
changeProgram( Texture2dProgram program )
Changes the program. The previous program will be released.
The appropriate EGL context must be current.
public void changeProgram(Texture2dProgram program)
Method Parameters
- program
createTextureObject()
Creates a texture object suitable for use with drawFrame().
public int createTextureObject()
drawFrame( int textureId, float[] texMatrix )
Draws a viewport-filling rect, texturing it with the specified texture object.
public void drawFrame(int textureId,float[] texMatrix)
Method Parameters
- textureId
- texMatrix
