] | There are a whole bunch of different ways to create 3D scans of objects these days. Researchers at the [UW Graphics Lab] have demonstrated
how to use a small, cheap time-of-flight sensor to generate scans effectively.
Not yet perfect, but the technique does work…
The key is in how time-of-flight sensors work. They shoo... | 7 | 4 | [
