This is a preliminary 3D model of the Tennesee State Prison made from images available online and taken from the "On the Inside" film showcasing the prison's architecture. It is preliminary, but already offers some interesting perspectives. For example, it is very hard to find images taken from the right side of the prison. It seems photographers, either by drone or by hand, tend to align their shots to catch the river and mountains in the background, avoiding the highway and industrial zones on the other side. This model is interesting because the TSP is currently not available to visitors.
I think the model could be improved quite a bit by using more images and processing on a higher quality setting. This was just a proof of concept attempt.
