EGLbased

EGLbased refers to software, libraries, or systems that rely on the EGL API to create and manage graphics rendering contexts and drawing surfaces across different windowing systems. EGL is a Khronos Group interface that provides an abstraction layer between rendering APIs, such as OpenGL ES and OpenVG, and native platform window systems. It also supports creating and binding rendering surfaces, and for some implementations, serves as a path to other APIs like Vulkan through extensions.

An EGL-based design decouples the rendering API from the underlying windowing system, enabling portable graphics across varied environments including embedded devices, Linux desktops, and mobile platforms. It enables features such as choosing rendering configurations, creating contexts, creating window or pbuffer surfaces, and switching the current context for rendering. This model supports both offscreen rendering and onscreen presentation via swap buffers, with additional extensions for advanced capabilities like surfaceless contexts or platform-specific surface creation.

Common use is found in Linux-based graphical stacks, Android, and embedded systems. Programs and environments that are described as EGL-based typically implement or rely on EGL to initialize rendering, interface with window managers or compositors, and drive the rendering loop independent of the specific graphics API in use. Notable ecosystem components include Wayland-based compositors and Mesa’s EGL drivers, as well as middleware like ANGLE that leverages EGL to bridge between APIs and platforms.

Overall, EGLbased denotes a broad approach where EGL provides the portability and lifecycle management necessary to render across diverse hardware and windowing layers, making it a foundational pattern for cross-platform graphics on Khronos-enabled systems.
