Experiential storytellers and attraction designers Holovis, presented the world’s first real-time interactive game solution in a 3D dome at IAAPA Attractions Expo in Orlando last November. In the run up to the show, Holovis promised visitors, “a highly compelling storyline with perfectly synched motion, and incredibly accurate interaction.”

Their stand was a ten metre inflatable dome, where up to 12 visitors on a seated motion platform could experience Crimson Wing, an interactive 3D game designed entirely by the Holovis Media team. As a world first, the 3D-immersive experience was rendered in real-time and projected onto the dome’s 360 degree screen. Visitors entering the MotionDome experienced the Holovis In-Mo game-engine system, featuring the Crimson Wing game, dynamic movement in the seats, and interaction using the specialist hand-held laser-tracked controllers.

Behind the scenes of the launch at IAAPA, Holovis sought out the services of Amalgam to develop the game’s controller shells. Amalgam’s role was to model and test the controller designs, then develop the prototype.
Holovis came to Amalgam with a basic outline shape developed as a 3D concept. The first priority was to develop the ergonomics, starting with the handle of the controller. To test each handle design, Amalgam cut controller handles out of modelling foam, using their 3-axis CNC machine. Once the team determined the desired shape and best size, Amalgam adjusted the CAD model and applied finer exterior design details to it.

The concept version was then shelled out, for Amalgam to apply all the required internal features and electronic support bosses. The next stage was to develop the files into a final design, which took a further four weeks of complex computer-aided design work.

After completing the CAD files, Amalgam 3D-printed a set of parts, for finishing and assembly to use as vacuum casting masters. The next step was to produce a set of soft tools, and finally a small batch of game controller casings. Amalgam then fitted the electronics inside, to complete the batch of prototypes destined for the show in Orlando.

Andy Biller, Project Lead at Holovis., said of these prototypes. “These prototypes will form part of an important and developing thread of our business over the next 12 months. It really does feel like working in an integrated team, with Amalgam contributing their insight and experience of materials and production techniques into the overall development process.”
