Detailed Description

Animated cycling switch node.

The SoBlinker class is derived from SoSwitch, so it selects one of its children to traverse. Using engines connected to the realTime global field, the whichChild field is animated over time. If the node has only one child, whichChild toggles between SO_SWITCH_NONE and 0, causing the child to be switched on and off repeatedly. If the node has more than one child, they are cycled through continuously.
