Extended Reality (XR) is the umbrella term that covers the technology stack of Virtual Reality (VR), Augmented Reality (AR) and Mixed Reality (MR). XR has seen rapid growth as a new medium for users to see and interact with data that would not be possible through traditional input devices. As adoption of this technology grows, it will drive the need to visualize increasing amounts of data. One of the major challenges to large data visualization in XR is that it either requires a tremendous amount of processing power to fully visualize the content, or extreme scale cuts must be made to show such data sets on lower end hardware like mobile devices or head-worn displays. This tutorial will cover lessons learned in visualizing extremely large data sets using the Unity Real-Time Development Platform, including challenges of visualizing vast amounts of 3D data using the traditional Unity Game Object system, associated limitations, and how to overcome them with Unity’s Data Oriented Technology Stack (DOTS). This tutorial will also provide a practical example to cover the visualization of publicly available 3D data from National Oceanic and Atmospheric Administration’s Multi-Radar/Multi-Sensor System as a source, including the data extraction process, initial testing with Unity’s traditional Game Object System, and the transition to the Unity DOTS that allowed for a jump from displaying a few hundred weather data points in 3D to over one million data points. This tutorial will also discuss the techniques that can be used to view and manipulate this data in XR along, with an evaluation of the benefits and limitations realized from utilizing the capabilities explored.
