LiveScan3D-Hololens

This application allows for streaming point clouds to a Unity application or to a HoloLens and rendering them. Together with our other application, LiveScan3D, it can be used for viewing 3D data captured in real time (for example for telepresence) or pre-recorded data.

You will find a short presentation of the application in the video below (click to go to YouTube):

How to get it running with LiveScan3D

First of all you will need to setup the following apps:

• LiveScan3D - our open-source app for 3D reconstruction using Kinects.
• Unity - the latest one that is known to work is 2018.4.14f1.
• Visual Studio 2019 - you will need this if you want to stream to a HoloLens, if you just want to stream to a Unity app you should not need it.

Once you have all the above open LiveScanServer, connect a client and open the live view window (it is the contents of that window that are streamed to Hololens). Alternatively, you can also use the LiveScanPlayer and play pre-recorded data. Next, start the Unity application on the same machine as the server, if everything is fine it should be working. If it is not working, let me know and I will try to fix it.

If you got this far, getting it to work on Hololens should be easy, just make sure you deploy the app using XAML UWP build type instead of D3D (this is required by the touch keyboard). Once you deploy and start the app on Hololens all you need to do is input the IP number of the server and you should see the point cloud. If there are issues try rebuilding NetworkCommunication in Release mode, the resulting dll files should be automatically copied to /Assets/Plugins/x86/

How to control the scene

The scene can be moved, scaled and rotated around the Y axis, the modes are chosen using the following voice commands:

• Move - the scene can be moved using the tap and hold gesture.
• Rotate - the scene can be rotated by using the tap and hold gesture and moving the hand horizontally.
• Zoom - the scene can be scaled using the tap and hold gesture and moving the hand horizontally.
• Reset - resets the scene to its original position, rotation and scale.
