3D reconstruction with Tango is relatively easy. Tango SDK include a function called Tango3DRExtractWholeMesh with will return a vertices[], a triangles[], a normal[] and a colors32[]. Once we put all of the arrays in a Mesh object and draw such object, you will have the 3D reconstruction of the room. Tango uses vertex coloring. The quality of the texture is not as good as HoloLens’s, which used projection texture mapping. However, Tango consume much less memory than HoloLens and the processing speed is viewably faster. We also made a small modification on HoloToolKit.SimpleMeshSerializer so it can serialize and deserialize the mesh that Tango create.
