The second example doesn't, IMO, demonstrate the kind of deformation tracking the example in the OP does. As far as I can tell, they are able to get a depth representation, segment objects from a video, get an approximation of surface normals and reflectivity for those objects, and project a shaded surface onto those objects. What they do not seem to be able to do without IR markers is project a diffuse texture to an object so that it would stick properly. See the one example with a non-uniform texture, where the fingers of a hand are fanned out - the texture warps noticeably.
