Snap invited me to create an AR lens experience for their Spectacles hardware.
My lens showcased 3D maps of bathemetry data around three island chains. I used the Gridded Bathymetry Data from GEBCO, processed it with gdal, and built 3D models with Blender.
From then on I built the lens in Snap's Lens Studio, starting with the scene positioning. The lens begins with a 2D menu to explain the interaction process and to swipe between bathymetry options, making use of the touchpad on the side of the Spectacles lenses.
The island models are colored with a gradient shader to indicat height, including contour lines for every 1000m. The lens also incorporates hand gesture tracking; when the user points with one finger, the map tilts on one axis. The Spectacles hardware includes pretty impressive scene-tracking, so the user is able to "place" a bathymetry map at a point in their room, and then walk around it to explore the contours.
