...This project explores how volumetric data can be represented in physical space with direct hand-tracking inputs in mixed reality using HoloLens 2. It is based on Microsoft's MRTK(Microsoft's Mixed Reality Toolkit). DataVisualizer.cs script contains the code for retrieving, parsing JSON data, and visualizing with graphs. Graph elements are added to GraphContainerConfirmed, GraphContainerRecovered, GraphContainerFatal, and LabelContainer. CreateMeshes() creates the graph for three data values and text label. Main menu's Radio buttons simply show/hide GraphContainer objects. Menu stays around the user with tag-along behavior which is provided by MRTK's RadialView solver. ...
