Spinifex Group – Jasper Dome

March 8, 2019

This installation was developer for the Royal Australia Air Force and displayed at the Australian International Airshow – Avalon 2019.

The project consisted of 2 applications developed in Unity. An Android app running on 16 Samsung tablets and a PC app running on a highly spec’ed PC, in a 15 metre dome with 8 projectors and speakers.

Some of the technology used for this installation included Omnity for the projection output, KlakNDI for the NDI output required by the projectionists, UNET for communication between the apps, Curvy Splines for plane paths, Post Processing Stack for visual effects. To keep things G rated Bad Word Filter PRO was used and Zenject for gluing it all together, also taking advantage of its pooling for spawning/despawning planes.

The PC had a 6th gen i7, 32GB RAM and was running a RTX 2080 ti. The tablets were Samsung Galaxy Tab S2. The NDI signal ran over a 10GBE card for the bandwidth required. The tablets used a POE switch for power and connectivity so we did not have to rely on WiFi which has a tendency to be flaky at public shows like this and constant connectivity is a must.

The projection app was also built in VR using SteamVR for internal and client reviews.

Unity 2018.3 was used for the projection app and was interesting to find new features and locations of settings and also to be able to use KlakNDI. The Android app used 2018.2.

The installation ran for 6 days on average for 12 hours a day.

Many were involved in the project including 3D artists, animators, sound artists, producers, technical directors and myself as the developer and onsite technical director. Massive project that was a team effort.

A constant flow of people kept the numbers in the dome anywhere from 10 to 50 – except when the fighter jets were blasting past outside and shaking the dome so everyone would rush out to catch the action.
