##<h4 align=right>interpolator</h4> 
##<p>This example is to illustrate the use of a 
##timesensor and interpolator. In another example,
##the interpolator will be replaced by a script.

##@ timesensor
## The TimeSensor activates the <font color=gold>color</gold> change
  DEF TIME TimeSensor { loop TRUE cycleInterval 5 } #<l++>
## We use a simple ColorInterpolator (analog)
  DEF COLORS ColorInterpolator {
	key [ 0 0.5 1 ]
	keyValue [ 1 0 0,  0 0 1, 1 0 0 ]
	} #<l++>
## # Finally, we wire the events
ROUTE TIME.fraction_changed TO COLORS.set_fraction
ROUTE COLORS.value_changed TO MATERIAL.diffuseColor
