Usage

From source file:SimpleTest.java

public TransformGroup createBehaviors(BranchGroup bg) {
    // create a TransformGroup.
    ///*from  w  w w.  j  ava  2s.  co m*/
    // A TransformGroup is a Group node (can have children)
    // and contains a Transform3D member.
    //
    // The Transform3D member contains a 4x4 transformation matrix
    // that is applied during rendering to all the TransformGroup's
    // child nodes. The 4x4 matrix can describe:
    // scaling, translation and rotation in one neat package!

    // enable the TRANSFORM_WRITE capability so that
    // our behavior code can modify it at runtime
    TransformGroup objTrans = new TransformGroup();
    objTrans.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);

    // create a new Transform3D that will describe
    // the direction we want to move.
    Transform3D xAxis = new Transform3D();

    // create an Alpha object.
    // The Alpha object describes a function against time.
    // The Alpha will output a value that ranges between 0 and 1
    // using the time parameters (in milliseconds).

            1000, 10000, 2000, 4000);

    // create a PositionInterpolator
    // The PositionInterpolator will modify the translation components
    // of a TransformGroup's Transform3D (objTrans) based on the output
    // from the Alpha. In this case the movement will range from
    // -0.8 along the X-axis with Alpha=0 to X=0.8 when Alpha=1.
    PositionInterpolator posInt = new PositionInterpolator(xAlpha, objTrans, xAxis, -0.8f, 0.8f);

    // set the range of influence of the PositionInterpolator
    posInt.setSchedulingBounds(getBoundingSphere());

    // wire the PositionInterpolator into its parent
    // TransformGroup. Just like rendering nodes behaviors
    // must be added to the scenegraph.
    objTrans.addChild(posInt);

    // add the TransformGroup to its parent BranchGroup
    bg.addChild(objTrans);

    // we return the TransformGroup with the
    // behavior attached so that we can add nodes to it
    // (which will be effected by the PositionInterpolator).
