OpenGL
OpenGL is a cross-platform, vendor-neutral graphics API for 2D and 3D rendering, originally derived from Silicon Graphics' IRIS GL and released in 1992 under the OpenGL Architecture Review Board (ARB). OpenGL became the de facto standard for CAD, scientific visualization, and pre-DirectX games, supported by NVIDIA, AMD, Intel, and Apple GPUs. Maintenance moved to the Khronos Group in 2006 and the API has continued evolving through OpenGL 4.6 alongside its successor Vulkan.
Why it matters
OpenGL democratized hardware-accelerated 3D — it's the API that allowed NX, CATIA, Creo, SolidWorks, Maya, and Houdini to run on the same commodity NVIDIA GPU. The shift from per-vendor APIs (graPHIGS, Starbase, IRIS GL, XGL) to OpenGL is the moment the workstation business model collapsed and PC-class hardware took over engineering computing — a structural change that still shapes how CAD vendors price, package, and deploy today.
