IRIS GL (Integrated Raster Imaging System Graphics Library) is a proprietary graphics API created by Silicon Graphics (SGI) in the early 1980s for producing 2D and 3D computer graphics on their IRIX-based IRIS graphical workstations.[1][2] Later SGI removed their proprietary code, reworked various system calls, and released IRIS GL as the industry standard OpenGL.
