# example of ProximitySensor node
# based on an example written By Fabiana
# Modified by Leo - 10-Sept-97
# in this example when the user enters the cube region (white one)
# the sensor will start the interpolator and interpolate a path
# for the green cube
# REMEMBER : to start the sensor you have to move the viewer to the
# sensitive region

# viewer initial position
