It combines the method of loci memory technique and 3D mixed reality interaction with mind maps (graphs) to support you on your personal analysis tasks. Loci is a method of loci mixed reality mind mapping application located around you. The application makes use of the Mixed Reality Toolkit for Unity and the UnityGLTF projects in order to read glTF files. The application relies solely on local networking technology and does not involve the setup of an external server nor does it make use of cloud services. This means that large, complex models are likely to suffer poor performance unless pre-processed to reduce complexity.

The application makes no attempt to alter the models you give it to suit the mobile processing capability of the HoloLens. If you have models in formats other than glTF then you can use utilities such as Paint3D to convert to glTF and save as. The user is always able to scale, rotate, translate and remove the models that they opened & the results of those operations are synchronised to other viewers. This 'sharing' feature allows for a group of users on a network to each have separate scenes made up of models that they have opened locally on a device intermingled with models which were originally opened by other users on other devices. Such a "shared" model will be displayed in the same physical location & updates to the model on the originating device will be replicated to all other viewers sharing that model. On a compatible network setup, when one user opens a model any other glTF Viewer users will be notified and offered a chance to bring this newly opened model into their scene. With your focus on a specific model, you can use the "reset" voice command to put it back to its original location and the "remove" voice command to delete it from your scene. You can open as many models as you like, the device will display them around 2m in front of you following your gaze and, once opened, you can use the regular one- and two-handed gestures to scale, rotate and move the model around in space. You should be able to load any models packaged as either single-files (.GLB) or multiple-files (.GLTF). Then run "glTF Viewer" and use the "open" voice command to choose the model that you want to display.

To get your glTF files onto your HoloLens, simply attach to a PC and use the built-in Windows support to copy your model files (.GLB/.GLTF) onto the storage on the device taking care to place them somewhere within the '3D Objects' folder.
