如何在Android上处理Sceneform/ARCore中的模型缩放？

// 导入必要的库和依赖
// 添加Sceneform插件和库的依赖
// 添加ARCore SDK的依赖

// 创建AR场景和添加模型
ArFragment arFragment = (ArFragment) getSupportFragmentManager().findFragmentById(R.id.ar_fragment);
arFragment.setOnTapArPlaneListener((hitResult, plane, motionEvent) -> {
    Anchor anchor = hitResult.createAnchor();
    ModelRenderable.builder()
            .setSource(this, Uri.parse("model.sfb"))
            .build()
            .thenAccept(modelRenderable -> addModelToScene(anchor, modelRenderable));
});

// 添加模型到场景
private void addModelToScene(Anchor anchor, ModelRenderable modelRenderable) {
    AnchorNode anchorNode = new AnchorNode(anchor);
    TransformableNode modelNode = new TransformableNode(arFragment.getTransformationSystem());
    modelNode.setRenderable(modelRenderable);
    modelNode.setParent(anchorNode);
    arFragment.getArSceneView().getScene().addChild(anchorNode);
    modelNode.select();

    // 处理模型缩放
    modelNode.getScaleController().setMaxScale(2.0f); // 设置最大缩放比例
    modelNode.getScaleController().setMinScale(0.5f); // 设置最小缩放比例
    modelNode.getScaleController().setSensitivity(0.1f); // 设置缩放灵敏度
    modelNode.getScaleController().setEnabled(true); // 启用缩放功能
}
