I've had a Structure Sensor for a couple of years now. They keep updating the software and firmware and improving the detail capture of the device. After the last round of updates I spent some time in the garage while it's -20°C and snowing outside in March to test out that new detail.You get all the Structure software with the scanner, but you can also use third party apps to operate the device. Itseez3d is one of those apps, but I always found it quite buggy. That all seems to be behind it with the latest update.
The model above is on Sketchfab, but itseez3d is doing something like it on its own website. The detail seems similar on both. I'd never been able to get a stable large scale model out of itseez3d before, I could this time. The level of detail and how well it paints the surface of the model using the ipad's camera to catch colour and texture is impressive. The pictures on the left are the Tiger inside and out as a model on the itseez3d site.
Even with the Structure software I'm finding that the quality of detail in the 3d models the scanner produces are always improving. A boxed capture of the front section of the Tiger was a way of working close enough to take in a lot of compound curves and mechanical parts to see how well the Structure sensors lasers could feel out those details. It's producing smoother, more accurate models than ever.
