Their <a href="/search?q=IRIS%20GL%20wikipedia&form=WIKIRE" h="ID=SERP,6274.1">IRIS GL</a> API became the industry standard, as IRIS GL was considered easier to use, and it supported <a href="/search?q=Immediate%20mode%20(computer%20graphics)%20wikipedia&form=WIKIRE" h="ID=SERP,6275.1">immediate mode</a> rendering, therefore being faster than competitors like <a href="/search?q=PHIGS%20wikipedia&form=WIKIRE" h="ID=SERP,6276.1">PHIGS</a>. <br /><br/>SGI's competitors (including <a href="/search?q=Sun%20Microsystems%20wikipedia&form=WIKIRE" h="ID=SERP,6280.1">Sun Microsystems</a>, <a href="/search?q=Hewlett-Packard%20wikipedia&form=WIKIRE" h="ID=SERP,6281.1">Hewlett-Packard</a> and <a href="/search?q=IBM%20wikipedia&form=WIKIRE" h="ID=SERP,6282.1">IBM</a>) were also able to bring to market 3D hardware supported by extensions made to the PHIGS standard, which pressured SGI to open source a version of IRIS GL as a public standard called OpenGL. <br /><br/>However, SGI had many customers for whom the change from IRIS GL to OpenGL would demand significant investment. Moreover, IRIS GL had API functions that were irrelevant to 3D graphics. For example, it included a windowing, keyboard and mouse API, in part because it was developed before the <a href="/search?q=X%20Window%20System%20wikipedia&form=WIKIRE" h="ID=SERP,6287.1">X Window System</a> and Sun's <a href="/search?q=NeWS%20wikipedia&form=WIKIRE" h="ID=SERP,6288.1">NeWS</a>. IRIS GL libraries also were unsuitable for opening due to licensing and patent issues .

However, their proposal for a C-style shading language was eventually completed, resulting in the current formulation of the OpenGL Shading Language (<a href="/search?q=GLSL%20wikipedia&form=WIKIRE" h="ID=SERP,6331.1">GLSL</a> or GLslang).
