[FEATURE] Live reconstruction of the 3d model

Capturing of the pointcloud snapshots usually is less usable than leave it for software to build the model from the captured points and update the model dynamically. So the next big future is live reconstruction of the 3d models.

Seems tango 3d reconstruction library is what we need to simplify the development of adopting the pointclouds.

Hmmm, that's weird, but I already get some results from tango library - something in obj format, looks like 3d mesh of combined pointclouds, but flipped and not well positioned. Need to check closely and adjust some settings.
Overall the tango reconstruction library is works well, just requires some wrapping and integrating in the H3DS project.

Right now it's adding snapshot to the Tango 3D Reconstructor with the camera position. Here is a couple of blender screenshots with imported obj files from Tango Obj mesh exporter:

• Piano one shot:
  

• Piano 4 shots with changing position - you can see that mesh is not overlapping, but trying to replace the old vertexes:
