Editing Scene graph (section)

==Standards==

===PHIGS===
[[PHIGS]] was the first commercial scene graph specification, and became an [[ANSI standard]] in 1988. Disparate implementations were provided by [[Unix]] hardware vendors. The [[HOOPS 3D Graphics System]] appears to have been the first commercial scene graph library provided by a single software vendor. It was designed to run on disparate lower-level 2D and 3D interfaces, with the first major production version (v3.0) completed in 1991.

===SGI===
[[Silicon Graphics]] (SGI) released [[OpenGL Performer]] or more commonly called Performer in 1991 which was the primary scenegraph system for most SGI products into the future. [[IRIS Inventor]] 1.0 (1992) was released by SGI, which was a high level scene graph built on top of Performer. It was followed up with [[Open Inventor]] in 1994, another iteration of the high level scene graph built on top of newer releases of Performer. More 3D scene graph libraries can be found in [[:Category:3D scenegraph APIs]].

===X3D===
[[X3D]] is a [[royalty-free]] [[open standards]] [[file format]] and run-time architecture to represent and communicate 3D scenes and objects using [[XML]]. It is an [[International Standards Organization|ISO]]-ratified standard that provides a system for the storage, retrieval and playback of real-time graphics content embedded in applications, all within an [[open architecture]] to support a wide array of domains and user scenarios.
