#X3D V3.0 utf8

#	Demonstration of a few event utility nodes.
#
#	This example illustrates a push-on/push-off switch.
#	The TouchSensor on the green cone controls the geometry of
#	the red object. It alternates between a cube and a sphere.
#
#	The EventUtility nodes wrapped up in the external PROTO
#	switchLocking. See switchLocking.x3dv for more details.
#	One of the output events (state) from the prototype is
#	sent to the Switch node for choosing the geometry.
#
#	The blue cone (on the left) also implements a locking switch
#	using the Script node. This is done for illustrative purposes.
