This is a demo of ARCore/Sceneform in action. The app allows the user to locate a surface, ideally a floor or table top, and place a graphical 3D virtual mansion in the space, grow or shrink it, rotate and move it, and explore the augmented three-dimensional space.
The mansion is based on a model publicly available here:

The application will run on Android ARCore-supported devices enumerated here:
