'''EGL''' is an [[Interface (computing)|interface]] between [[Khronos Group|Khronos]] [[rendering API]]s (such as [[OpenGL]], [[OpenGL ES]] or [[OpenVG]]) and the underlying native platform [[windowing system]]. EGL handles graphics context management, [[Computer representation of surfaces|surface]]/[[Data buffer|buffer]] binding, [[Rendering (computer graphics)|rendering]] synchronization, and enables "high-performance, accelerated, mixed-mode [[2D computer graphics|2D]] and [[3D computer graphics|3D]] rendering using other Khronos APIs."<ref>{{Cite web|url=https://www.khronos.org/egl/|title=EGL Overview, Native Platform Interface|date=July 19, 2011|website=The Khronos Group}}</ref> EGL is managed by the [[Non-profit organization|non-profit]] technology consortium [[Khronos Group]].
