How to Remove 3d objects which are placed on AR Screen

Question

I have an AR Screen where I placed some 3d objects. I am using google AR Core with android SDK.

I need to remove those objects from the scene on clicking of a clear button.

I was able to remove the last placed object. But the other objects were not removing.

This is the code i am using.

if (newAnchor != null) {
            arFragment.getArSceneView().getScene().removeChild(newAnchor);
            newAnchor.getAnchor().detach();

Answer 1

you can detach android model from scene form using below code

 List<Node> children = new ArrayList<>(arFragment.getArSceneView().getScene().getChildren());
        for (Node node : children) {
            if (node instanceof AnchorNode) {
                if (((AnchorNode) node).getAnchor() != null) {
                    ((AnchorNode) node).getAnchor().detach();
                }
            }
            if (!(node instanceof Camera) && !(node instanceof Sun)) {
                node.setParent(null);
            }
        }
