Week 5, 3D modeling, ethics, Photogrammetry, reflection

This week we both explored online exhibitions of 3D models and scanned objects in the Perlman Teaching Museum to create 3D models. When viewing online exhibitions, I was astonished by the details of the scan and the immense possibilities of tools (showing dimensions, creating tags, having a tour, etc). However, when I did the photogrammetry, I realized how difficult it is to create a model. After taking photos and generating the raw model, we attempted to fix the holes and remove the holder of the object. This process required us to use the “remove” and “fill” tools in Recap Photo Pro repeatedly and rotate/zoom to find a suitable angle. Through fixing, I had to examine the object closely and notice many details I might otherwise have ignored. For example, paints were peeled off in some parts, but some remained. I wondered what color it used to be and if it was already off when excavated or due to improper preservation.

As an observer, I think 3D modeling and immersive environments are great tools to present art and history to the general public. I could see details better and examine objects from different angles compared to in museums. Immersive environments create context and help me imagine better. However, when I become an active modeler, I found that recreation involves imagination of producers, and might not yeild the most accurate representation. I am concerned about misrepresentation, especially those involve cultural heritage. It could be unrespectful if people who create those models lack the appropriate cultural knowledge. The Hampson Archeological Museum State Park collection addresses the problem by providing actual photos along with the objects. I also hope to discuss the ethics of publishing such materials online. Who has the ownership of the objects and the models? It is also hard to prevent people from misusing the models. The Virtual Hampson Museum website had to remove the ability to download 3D object models because many users were violating the Creative Commons licensing. I wonder if there are better solutions to this problem than removing the access as a whole.
