I have an app idea that would map an OLD photo onto the front of the same existing building. The underlying work has already been done see https://lowestoftoldandnow.org/full/strolleast#45 but obviously you would have to accurately record 4 points in 3d space but also the user of the app would have to take these points (given to them by the app) and map them back onto the real world with the same accuracy. If the photo was partly on the next door building it would not work. I am beginning to think that the technology is not there yet :-(

Scenario: building with old shopfront to be renewed, we have a visual of new concept. Is there an app that can give us the coordinates in line with the plane of the front of the building so we can map the visual on and it alter perspective as you walk around as it ‘sticks’ to front of real building please? Gif attached is visual concept but showing historic pic
