Unity 2017.3.1f1 (64-bit)
A proof-of-concept of an interactive augmented reality building performance visualization interface, developed for the new headquarters of the Harvard Center for Green Buildings and Cities, and demoed at open house events in April 2018. Built in Unity for the Hololens. Project is also synced to Unity Collaborate.
Download the project from GitHub or Unity Collaborate, and select the scene HZHololens2018. Build for the Hololens (UWP device) and deploy from Visual Studio.
Note that the project utilizes a HTTP connection to receive CFD data, as well as a connection to a WebSocket server for broadcast sensor data.
The main visualization features two scales: a full- or room-scale view designed to overlay information on to the actual HouseZero, and a miniature-scale view which displays the proposed building for the Havard CGBC.
The full- or room-scale view includes:
- prototyped sensor values (temperature and humidity)
- a virtual operable window and associated airflow
- a behind-the-wall visualization of infrastructure
- an interactive section of the CFD data
- annotations for the above
The miniature-scale view includes:
- a model of HouseZero and an associated visualization of CFD data
- a control panel UI
All scripting completed in C#. As much as possible, comments have been provided in the code for legibility.
The CFD models are generated by the miniCFD and roomCFD GameObjects from a CSV, accessed via an HTTP connection. The cooresponding URL can be changed via Inspector panel using the Url field within the get_JSON script component. Alternatively, the CSVs can be stored locally for offline operation in the Local Url field. The VMin, VMax, YMin, YMax fields have been preset to fit the data.
TBD
A proof-of-concept level of interactivity is accomplished by transforming standard sliders, and hiding their cooresponding mesh renderers. The project reuses GUI and interaction assets from the Microsoft Mixed Reality Toolkit for Unity
Main design and development team: Spyridon Ampanavos, Yuan Gao, Brian Ho, Jiho Song.
Project led by Stephen M Ervin, in partnership with the Harvard CGBC directed by Ali Malkwai.
