Summary

VRML objects (the objects in your world created from one of the 54 node classes) don't have variables. Instead, they have:

• Fields, which are parameters that are only used when the object is created.
• EventOuts, which allow the object to send an event corresponding to (part of) the object's internal state. Once the scene is initialized, those events are sent only when the state changes.
• EventIns, which are methods for changing an object's internal state, and often its appearance in the scene.
• ExposedFields, which are nothing more than a combination of a field, an eventIn, and an eventOut.
