VRML (cont...)
Key Concepts (cont...)
- Grouping nodes can contain any number of other nodes (children)
- An Inline node is a kind of grouping node where the child nodes are defined in another VRML file
- New node types can be created using prototype definitions
- Most node types have eventIn and eventOut fields
- A 'route' can be used to connect a node's eventOut field to another node's eventIn field, enabling nodes to send events to each other
- Events typically contain values that affect the state of the receiving node
- Dynamic environments can be created by wiring nodes together into circuits
