	PHIGS - Wikipedia, the free encyclopedia
		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.
		PHIGS originally lacked the capability to render illuminated scenes, and was superseded by PHIGS+.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").

	Differences between the OpenGL and PHIGS model (Site not responding. Last check: 2007-09-07)
		PHIGS uses 4 transformations to specify a view and a projection whereas OpenGL only uses 3.
		The view mapping transformation in PHIGS is difficult to understand in the case of perspective projection.
		The view-orientation transformation in PHIGS translates the reference point to the origin van het normalized projection coordinate system, whereas in OpenGL the viewing transformation moves the eyepoint to the origin of the eye coordinate system.

	An Introduction to PHIGS by Terry Smith
		Because of its display list system structure, PHIGS is well-suited to applications that create a graphics model and then edit portions of it frequently or view it in different ways (Gaskins 1).
		Thus, PHIGS is very appropriate for most engineering and industrial applications but may not be adequate for more advanced visualization.
		PHIGS can be used alone to create graphics; however, using PHIGS and X together, you can use Xlib or an X toolkit to create other features such a user interface and allow PHIGS to control the graphics.

	PHIGS - Programmer's Hierarchical Interactive Graphics System
		PHIGS, short for the Programmer's Hierarchical Interactive Graphics System, is basically a library of about 400 functions that allow the user to display and interact with 2-D and 3-D graphics.
		PHIGS hides hardware-dependent details from the user; so, for example, it allows an application draw on a plotter the same way it draws on a computer screen.
		It is not recommended to use PHIGS for animation, except for simple graphics objects (wireframes, for example).

		In addition to the these activities, the committee has participated in the PHIGS republication efforts, the finalization of CGM amendments, the continued development of the committee’s imaging standards base and the continued persuit of commercial and industry based standardization opportunities (such as the Java windowing API).
		The reason for the delay in the PHIGS archive, the PHIGS archive clear text encoding, and the PHIGS C language binding are all due to the fact that these standards by definition need to lag the functional specifications by at least one cycle.
		The editors for all of the PHIGS amendments were provided by H3 and the PHIGS republication editors are provided by the BSI.

		The PHIGS system is a computer graphics standard defining an interface between an application program and a computer graphics system.
		The PHIGS standard has received wide acceptance throughout the computer graphics industry and PHIGS libraries are available on most of the high-performance 3-D graphics platforms today, including IBM, DEC, HP, SUN, Alliant, Stardent, and Silicon Graphics.
		The sections begin with a conceptual discussion of the PHIGS topics presented in that section and is followed by a detailed explanation of an example program or subroutine.

		If the event queue is not empty, PHIGS sets the variable pointed to by ws_id to the identifier of the workstation that was the source of the input event.
		If the event queue is not empty, PHIGS sets the variable pointed to by class to the class of the device that generated the input event.
		While PHIGS is in a wait state, window system events such as repaints, resizes, and so on are processed as usual.

		Input is managed by an independent process called the PHIGS Input Manager (PIM), which communicates with the drivers.
		The PIM allows input to be disassociated from output and, thus, provides the same look and feel regardless of the hardware and driver used.
		The PHIGS PLUS (Plus Lumière Und Surfaces) functions provide a more realistic representation of 3D objects by using algorithms for shading (Gouraud, flat), lighting (light sources and surface properties), processing smooth curves and surfaces (NURBS) and associating complementary data with geometric primitives (With Data).

		This manual generally assumes that the Silicon Graphics Iris implementation is being used, and although informative comments concerning certain other implementations appear throughout the text, capabilities of the PHIGS implementation are not covered by such comments.
		Differences among implementations impact the program's ability to use graphical features that are based on 3D polygons, the user's ability to manipulate the graphical displays, and the user's ability to obtain alternate forms of output.
		With the PHIGS implementations of PLOT3D, views can be manipulated using keyboard commands or a three-button mouse, and users are potentially able to produce files for a variety of output devices.
