Their IRIS GL API was considered state-of-the-art and became the de facto industry standard, overshadowing the open standards-based PHIGS.

By contrast, PHIGS was considered difficult to use and outdated in terms of functionality.

GKS was later extended into a 3D version, and additions to this resulted in PHIGS ( Programmer's Hierarchical Interactive Graphics System ), a competitor to OpenGL.

PHIGS was the first commercial scene graph specification, and became an ANSI standard in 1988.

A descendant of GKS was PHIGS.

Their GX4000 product was a combination of PHIGS + software and special graphical boards that could generate and display graphical vectors very fast.

PHIGS was available as a standalone implementation ( examples: Digital Equipment Corporation's DEC PHIGS, IBM's graPHIGS, Sun's SunPHIGS ) and also used with the X Window system, supported via PEX, the " PHIGS Extension to X ".

Displaying graphics on the screen in PHIGS was a three-step process ; first the model would be built into a CSS, then a workstation would be created and opened, and finally the model would be connected to the workstation.

PHIGS originally lacked the capability to render illuminated scenes, and was superseded by PHIGS +.

PHIGS + works in essentially the same manner, but added methods for lighting a 3D scene, and was often referred to as PHIGS PLUS ( where the PLUS was a slightly tongue-in-cheek acronym for " Plus Lumière Und Shading ").

For simple projects, PHIGS was considerably easier to use and work with.

This was kept private in PHIGS, making it much more difficult to tune performance, but enabling tuning to happen " for free " within the PHIGS implementation.

PHIGS ( Programmer's Hierarchical Interactive Graphics System ) is an API standard for rendering 3D computer graphics, at one time considered to be the 3D graphics standard for the 1990s.

SGI's competitors ( including Sun Microsystems, Hewlett-Packard and IBM ) were also able to bring to market 3D hardware, supported by extensions made to the PHIGS standard.

NURBS are commonly used in computer-aided design ( CAD ), manufacturing ( CAM ), and engineering ( CAE ) and are part of numerous industry wide used standards, such as IGES, STEP, ACIS, and PHIGS.

Color recovery does rely on software support which is provided by libraries such as PHIGS, PEXLib, Starbase and even Xlib although Xlib does not enable it by default.

The word " hierarchical " in the name refers to a notable feature of PHIGS: unlike most graphics systems, PHIGS included a scene graph system as a part of the basic standard.

CSSes could be shared among a number of views, known under PHIGS as a workstation.

PHIGS + also introduced more advanced graphics primitives, such as NURBS surfaces.

OpenGL, unlike PHIGS, is an immediate-mode rendering system with no " state "; once an object is sent to a view to be rendered it essentially disappears.

PHIGS fell into disuse.
