IRIS GL
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. Later SGI removed their proprietary code, reworked various system calls, and released IRIS GL as the industry standard OpenGL. == History == In 1982, SGI began development of IRIS GL. It soon became much more popular than the ANSI standard PHIGS, as developers considered it more intuitive and flexible.
