Simple hole filling
Does anyone know of any simple hole filling algorithms available for post-processing the meshes from HoloLens?

Not exactly, but plane finding will sometimes fill holes. I don't think that a great hole-filling algorithm has been developed yet.
I believe that the spatial understanding feature that was recently added to the HoloToolkit does some amount of hole filling. I'm not sure if code for the native side of this plugin has been checked in yet, but once it is you will see that they do a lot of work in processing the raw meshes into voxels, and they can leverage this processing to do a better job at filling the correct parts of the mesh. You might want to load up the spatial understanding sample scene and see if it fills in the gaps you are seeing.

I would recommend getting familiar with Holograms 230, at at least the code. It shows you some additional options to increase the quality of the scan itself, and then process the mesh into planes.

Does that code actually mention anything about hole filling, other than fitting planes to surfaces?
