Class value_changed
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).

This program uses the
X3D Java Scene Access Interface Library (X3DJSAIL).
It has been produced using the
X3dToJava.xslt
stylesheet
(version control)
which is used to create Java source code from an original .x3d
model.
