Replace node renderable ( same rotation, position and scale ) with another node renderable in Sceneform sdk


I am new to sceneform sdk for Android . I have added one Transformable Node , then i applied some rotation , scaling and changed its position also. Now on click of button i need to place second node with same rotation , scaling and position.

For that what i did is:

 Node nodeTwo = new Node(); // second node
 nodeTwo.setLocalPosition(nodeOne);
 nodeTwo.setLocalRotation(nodeOne);
 nodeTwo.setLocalScale(nodeOne);
 nodeTwo.setRenderable(renderable); 

I have also tried with setWorldPosition() , setWorldRotation().. But nothing works , second node got placed on fix position and rotation.

Can I do something to 'fix' this?


Solution

  • anchor = hitResult.createAnchor();
            anchorNode = new AnchorNode(anchor);
            anchorNode.setParent(arView.getArSceneView().getScene());
            transformableNode = new TransformableNode(arView.getTransformationSystem()); // As you said i have added one transformablenode which will allow transformation.
            transformableNode.setParent(anchorNode);
            transformableNode.setRenderable(modelRenderable);
            transformableNode.select();
    

    Then i added another node which is going to replace first one with same transformation.

     Node node = new Node();
            Vector3 position = transformableNode.getLocalPosition();
            Quaternion rotation = transformableNode.getLocalRotation();
            TransformableNode andyNOde = new TransformableNode(arView.getTransformationSystem());
            andyNOde.setRenderable(andyRenderable);
            andyNOde.setLocalPosition(position);
            andyNOde.setLocalRotation(rotation);
            andyNOde.setParent(node);
            anchorNode.removeChild(transformableNode);
            anchorNode.addChild(node);
    

    It is working with this code, may be you were doing something wrong, check your code twice. Hope it will help!
