## Detailed Description

**This is the set of items specified by VRML97, also known as VRML2.0. These nodes are different from VRML1/Inventor nodes in the way you structure them into scene-graphs, and in the requirements they set for traversing them correctly (VRML1/Inventor require that you traverse siblings on the left side before the node of interest, while for VRML2.0 this is not true).**

**You can find out more about VRML97 in The Annotated VRML2.0 Reference Manual.**

**The VRML97 specification is online at http://www.web3d.org/x3d/specifications/vrml/**
