(Part I) This session invites participants who are willing to share not only what works in their 3D VR reconstructions, but also the lessons learned. The organizers are interested to hear how the 3D models do, or do not answer research questions; enable or fail to make arguments; solve or provide theoretical problems; whether the model succeeds or does not succeed to connect to the underlying data; whether the model stands on its own, or can be linked to others. The form of the session is a series of short presentations followed by discussion of the main themes. This leads to suggestions on how to improve workflow, software use and communication around 3DVR models. The participants will demonstrate their models and the way they are made accessible in a parallel presentation to show the audience in detail what the issues and solutions are. This has the form of a mini digital poster session, focused on discussing the caveats and accomplishments.
