Augmented reality smart city installation.

Competition

Components

1. 3D model of a city
2. three.js scene rendered in chrome sent to a projector
3. live data to display

Hardware

This installation requires the following:

1. A small PC or single board computer. We used the Okdo ROCK 5 B. We also purchased a M.2 Wireless module and a heatsink and fan.
2. A projector. We used the Sony VPLPHZ51.
3. Housing for the SBC and projector so they can be mounted on a wall and not stolen. We used an Integra H181608HLL.

Assemble the equipment, cut a hole in the housing for the projector to project through, and a few holes for ventilation near the fans.

For the 3D model, we used a CNC machine to cut rigid extruded polystyrene sheets. These were then coated in a few layers of watered down PVA glue to seal it, and then spray painted white.

Code to generate the 3D model is contained in src/python/. Set the bounding box and physical dimensions you're interested in in params.json5, then you can run get_elevation.py to pull high resolution elevation data from our web server. You can then run make_stl.py to convert that elevation data to a mesh that can be CNC machined. Alternatively you can use another service such as this.

Software

1. Download or clone this repository
2. Install Node.js
3. Install the required dependencies with npm install
4. Install webpack with npm install -g webpack (may require sudo)
5. For the data sources, you need to get your own keys to access them. For the data sources that are set up by default, you should: 1. Rename keys_template.json5 to keys.json5. 2. Go to https://opendata.transport.nsw.gov.au/ and create an account. After you have an account you can make an API key, with will be a long string. Copy that string into the placeholder in keys.json5. 3. Register another account with https://opensky-network.org/ to get flight data and copy the API key across. 4. Register another account with https://aisstream.io/ to get marine data and copy the API key across.
6. Open a terminal and navigate to the project directory. Run npm start to start the server and open a browser window with the projector interface.

Usage

Many system parameters are controlled by URL flags, such as debug which can be used as:

http://localhost:8080/?debug

which will put the system in debug mode. These flags are currently undocumented and you need to hunt for them in the code. YMMV.
