These scripting examples illustrate how to use the original External Authoring Interface (EAI) in the VRML97 specification. It allows scripts placed in an external HTML page to communicate with a VRML97 scene, using either Java or ECMAScript .
These HTML scripting techniques were later unified with Script syntax inside the scene as the X3D Scene Authoring Interface (SAI).
