[JAVA3D] How to update position for animation?

[Saeed Ansari]

Hello all,

I have added Some objects and an PositionInterpolator for each  to a TransformGroup.

As you see code below, I add PositionInterpolators to a list to modify them later.

As I am working on a simulation project, I get the position of objects every 100 miliseconds

and I want animate the motion of object.I update the setTarget method, but nothing happens.

How should I do this ? It is somehow complicated for me .

 

Regards,

Saeed

 

TransformGroup agentTrans = new TransformGroup();
        agentTrans.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
        agentTrans.setCapability(TransformGroup.ALLOW_PICKABLE_READ);
        agentTrans3D = new Transform3D();
        atMulRotation = new Transform3D();
        agentTrans3D.setTranslation(new Vector3f(xxx, yyy, 3.0f));
        agentTrans3D.setScale(0.1f);
        atMulRotation.rotX(1.5f);
        agentTrans3D.mul(atMulRotation);
        agentTrans.setTransform(agentTrans3D);
        bg=new vrmlLoad("ambulance.wrl");
        PositionInterp olator posInt = new PositionInterpolator(alpha , atGroup[i-1]);
        posInt.setSchedulingBounds(new BoundingSphere());
        atInterpolator[i-1]=posInt;
        agentTrans.addChild(bg);
        agentTrans.addChild(posInt);
        atGroup[i-1] = agentTrans;
        bg1.addChild(agentTrans);
