\page implementationNotes Implementation Notes

The Layer Management service consists of platform independent
and platform dependent components. On each platform a separate
renderer and if required a separate communicator have to be
implemented.

\section implementationNotesReferenceCommunicator Reference Communicator

The GENIVI reference communicator implementation depends on either
\li DBUS interface
or
\li TCP/IP sockets.

\section implementationNotesOpenGLRenderer OpenGL Reference Renderer

The OpenGL based renderer uses
\li X-Composite
\li X-Damage

to access the content of different applications and depends on
\li the glx extension GLX_EXT_Texture_from_pixmap
\li the blending mode of OpenGL

for compositing.

\section implementationNotesOpenGLESRenderer OpenGL ES 2.0 Reference Renderer

The OpenGL ES 2.0 based renderer uses
\li X-Composite
\li X-Damage 

to access the content of different applications and depends on
\li glEGLImageTargetTexture2DOES
\li eglCreateImageKHR
\li eglDestroyImageKHR
\li support for creating an egl image from an X11 pixmap

for compositing.
