17	<meta name='description' content='Test of a PositionInterpolators ability to set its initial "value_changed" field to the correct value prior to receiving any events. Two PositionInterpolator node are associated with two seperate Box geometry. The PositionInterpolator associated with the Box on the left has a keyValue of 0 0 -4, while the PositionInterpolator associated with the right Box has the default of no keyValues, or [ ]. As a result, the PositionInterpolator on the left should initialize its "value_changed" field to the value of its first keyValue, or 0 0 4. Because no keyValues are provided to the right PositionInterpolator, it should initialize its "value_changed" field to the SFVec3f default value of 0 0 0. A Script node reads this value for each PositionInterpolator, and will translate the associated Box by a value equal to its initially read "value_changed" SFVec3f value when the geometry is indicated by the pointing device. When the pointing device passes over the left Box, it should translate by a value of 0 0 4 (move forward) each time it is indicated,then return to its original position when no longer indicated. When the pointing device passes over the right Box, it should translate to a value of 0 0 0 (it should NOT MOVE).'/>

Event Graph ROUTE Table entries with 2 ROUTE connections total, showing X3D event-model relationships for this scene.

Each row shows an event cascade that may occur during a single timestamp interval between frame renderings, as part of the X3D execution model.
