解决方案

If you use ViewRenderable of Sceneform, then you can create a wall in AR space from 2D png image just like standard android widgets.

This is an example of layout xml for ViewRenderable. As you know, it's just a layout xml for Android apps ;)

<?xml version="1.0" encoding="utf-8"?>
<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/imageCard"
    android:layout_width="123dp"
    android:layout_height="197dp"
    android:src="@drawable/Your_Image_Resource" />

And you can get ImageView instance in your Java code like below to set a source image dynamically.

ViewRenderable.builder()
    .setView(fragment.getContext(), R.layout.imgboard)
    .build()
    .thenAccept(renderable -> {
        ImageView imgView = (ImageView)renderrable.getView();
    });

This is my sample shot with using ViewRenderable, the object on the far right was created from a png image.
