This model represents the results of a first pass using the default settings in Regard3d on a series of photographs taken from a balloon.
Regard3d crashed while generating the surface. Interestingly, you can see that most of the textures were applied nevertheless. So the surface was generated; it was in the final painting that things broke. Perhaps this was a memory issue on my end. In the centre of the portico you can see quite clearly the edges of one of the photo textures that was not applied.
