Appendix A: Node Reference

Node Reference

This section lists all the VRML nodes and their fields. Each definition contains:

• the node's name (e.g. Sphere)
  
• each field name (e.g. radius)
  
• default value for each field (e.g. 1)
  
• the field type (e.g. field)
  
• field value type (e.g. SFFloat)
  
• the range of acceptable values (e.g. (0,) indicates that the value must be greater than zero but less than infinity, square brackets indicate an inclusive boundary, e.g. [0,1] means 0 <= value <= 1)

EventIn and eventOut fields cannot be set when writing a VRML node, so are shown in a light type. The symbols on the left of each node name, indicate the type and properties of that node.

	Grouping node that has a field containing children nodes.
	Child node. Typical functions:
		light source
		sensor
		interpolator (for key-frame animation)
		time dependent node (activate and deactivate at specific times)
		bindable node (only one node of each type can be bound at a time)
	Property node, used in particular fields of child nodes.
		node appears in the geometry field of the Shape node
		node used within one of the fields of the Appearance node
		geometric property node, used within geometry nodes.
