ARCore model size
问题
我正在尝试将一个3D模型放入ARCore框架中，但是当我要放置这个模型时，它会变得过大，并且不会出现在屏幕中央。我不想通过点击来放置它，应用会自动地放置这个模型。
Anchor newMarkAnchor = session.createAnchor(frame.getCamera().getPose().compose(Pose.makeTranslation(0, 0, -0.5f)).extractTranslation());
AnchorNode addedAnchorNode = new AnchorNode(newMarkAnchor);
ModelRenderable.builder().setSource(getApplicationContext(), R.raw.imac).build().thenAccept(modelRenderable -> renderable = modelRenderable).exceptionally(throwable -> {Log.i("asdasdasd", "error: "+throwable.getLocalizedMessage());
return null;
});
addedAnchorNode.setRenderable(renderable);
addedAnchorNode.setParent(arSceneView.getScene());

I'm tring to put a 3D Model into an ARCore Frame, but when I'm going to place the model it comes oversized and does not appear at the center of the screen. I don't want to place it with a tap, the app places the model automatically .
Anchor newMarkAnchor = session.createAnchor(frame.getCamera().getPose().compose(Pose.makeTranslation(0, 0, -0.5f)).extractTranslation());
AnchorNode addedAnchorNode = new AnchorNode(newMarkAnchor);
ModelRenderable.builder().setSource(getApplicationContext(), R.raw.imac).build().thenAccept(modelRenderable -> renderable = modelRenderable).exceptionally(throwable -> {Log.i("asdasdasd", "errore: "+throwable.getLocalizedMessage());
return null;
});
addedAnchorNode.setRenderable(renderable);
addedAnchorNode.setParent(arSceneView.getScene());

检查您的模型在3D软件中的尺寸，在ARCore中，虚拟世界中的1个单位相当于现实世界中的1米。
看起来您正在使用Sceneform，是吗？您可以通过setWorldScale(Vector3)或setLocalScale(Vector3)轻松地缩放您的节点。
英文:
Check the dimensions of your model with 3D software, in ARCore 1 unit in the virtual world is equivalent to 1 meter in the real world.
Looks like you're using Sceneform, is this correct? You can scale your Node easily through setWorldScale(Vector3) or setLocalScale(Vector3).
