It was 3DConverterHD by ARVision. It really was slow on the iPad 3 but converted in real time as you finger painted the depth layers in IPad Air and newer. It has not been on App Store for a couple of years.
I used to be asking myself..."why do people take photos of machinery....how boring is that?" But now I have come to realize that if the viewer considers these types of photos as "examples of the ingenuity or man" that in that consideration they do become worthwhile. So, keep up the good pursuit of such photos!
Nice. What a fun new toy to play with. Too bad about the moving cars but that is one of he hazards of doing this with a single camera. Good shot, keep up the experiments with it.
