Mesa is hosted by and was initiated in August 1993 by Brian Paul, who is still active in the project.
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 Open GL specification.
The supported version of the different graphic APIs depends on the driver, because each hardware driver has its own implementation (and therefore status).
This is specially true for the "classic" drivers, while the Gallium3D drivers share common code that tend to homogenize the supported extensions and versions.
Gordon can travel from the first moments on the train all the way through the Lambda Core stages, while the final Xen stages and multiplayer maps will come a bit later.Mesa, also called Mesa3D and The Mesa 3D Graphics Library, is an open-source device driver and software implementation of the Open GL, Vulkan and other specifications.Its most important user surfacing parts are the two graphics drivers mostly developed and funded by Intel and AMD, which are using those implementations. The long awaited Black Mesa Source mod is available to download (or at least it will be once the site comes back to life, it's just been hammered by thousands of eager fans).We'll post a download link as soon the smoke clears, here's the dead website for now.
