EGL™ is an interface between Khronos rendering APIs such as OpenGL ES or OpenVG and the underlying native platform window system. It handles graphics context management, surface/buffer binding, and rendering synchronization and enables high-performance, accelerated, mixed-mode 2D and 3D rendering using other Khronos APIs. EGL also provides interop capability between Khronos to enable efficient transfer of data between APIs – for example between a video subsystem running OpenMAX AL and a GPU running OpenGL ES.
EGL provides mechanisms for creating rendering surfaces onto which client APIs like OpenGL ES and OpenVG can draw, creates graphics contexts for client APIs, and synchronizes drawing by client APIs as well as native platform rendering APIs. This enables seamless rendering using both OpenGL ES and OpenVG for high-performance, accelerated, mixed-mode 2D and 3D rendering.
