What is it about?
Reproducing dynamic changes in object geometry is an important issue in 3D reconstruction. In this study, we reproduced a dynamic 3D model of a simple articulated object with a rotating joint from a static point cloud, referring only to a video of the motion and a manually specified rotation axis. The actual reconstructed cultural asset was used for first-person experiences in an augmented reality environment.

Why is it important?
Virtual space can eliminate the physical constraints of real space. Three-dimensional (3D) digital twins enable us to touch cultural assets that are inaccessible in real space. In addition, it is important not only to physically preserve cultural assets, but also to preserve the ways in which they are moved and used. The creation of a virtual space in which people can experience the manipulation of cultural assets will be a great help to the assets' preservation. However, most 3D models obtained using current reconstruction techniques are static; they cannot be dynamically manipulated. We proposed a method to reproduce the dynamic 3D model from the reconstructed model, and we showed that the method allows us to simulate the experience of manipulating cultural assets in a virtual space.
Perspectives
Virtual preservation of cultural assets will become more common if it is possible for everybody to easily preserve not only the form but also the manipulation and experience of cultural assets. We hope that virtual preservation will become a more effective means of passing on culture to more people.
