Mesa is also not specific to Unix-like operating systems: on Windows for example, Mesa provides an OpenGL API over DirectX. But Mesa can implement other APIs and indeed it did with Glide (deprecated) and Direct3D 9 since July 2013.
Historically the main API that Mesa has implemented is OpenGL, along with other Khronos Group related specifications (like OpenVG, OpenGL ES or recently EGL). Mesa is known as housing implementations of graphic APIs. On the GDC 2014, AMD was exploring a strategy change towards using DRM instead of their in-kernel blob. The special library called libwayland-EGL, written to accommodate access to the framebuffer, should have been made obsolete by the EGL 1.5 release. The free implementations of Wayland rely upon the Mesa implementation of EGL.
For Linux, development has also been partially driven by crowdfunding. Mesa was subsequently widely adopted and now contains numerous contributions from various individuals and corporations worldwide, including from the graphics hardware manufacturers of the Khronos Group that administer the OpenGL specification. Mesa is hosted by and was initiated in August 1993 by Brian Paul, who is still active in the project. An open-source effort to write a Mesa Nvidia driver called Nouveau is mostly developed by the community.īesides 3D applications such as games, modern display servers ( X.org's Glamor or Wayland's Weston) use OpenGL/ EGL therefore all graphics typically go through Mesa. Proprietary graphics drivers (e.g., Nvidia GeForce driver and Catalyst) replace all of Mesa, providing their own implementation of a graphics API. Its most important users are two graphics drivers mostly developed and funded by Intel and AMD for their respective hardware (AMD promotes their Mesa drivers Radeon and RadeonSI over the deprecated AMD Catalyst, and Intel has only supported the Mesa driver). Mesa translates these specifications to vendor-specific graphics hardware drivers. Mesa, also called Mesa3D and The Mesa 3D Graphics Library, is an open source implementation of OpenGL, Vulkan, and other graphics API specifications.
Cross-platform ( BSDs, Haiku, Linux, etc.)
