Foil 50 Events

From VRML 2 Basic Concepts and Definitions CPS616 -- Information Track of CPS -- Spring Semester 97. by Zeynep Ozdemir(Geoffrey C. Fox)


Nodes can receive a number of incoming set_ events, denoted as eventIn, (such as set_position, set_color, and set_on), which typically change the node. Incoming events are data messages sent by other nodes to change some state within the receiving node.
Nodes can also send out a number of _changed events, denoted as eventOut, which indicate that something in the node has changed (for example, position_changed, color_changed, on_changed).
The exposedField keyword may be used as a short-hand for specifying that a given field has a set_ eventIn that is directly wired to a field value and a _changed eventOut.
