65 TECHFEED Game Engines
and VR headsets are all now being used to control interactive content and capture animation data, and also return power to the director. For example, instead of keyframing camera moves, you can perform virtual cinematography in Unreal or Unity from an iPad using the DragonFly app from Glassbox. doing professional media production can get started working with game engines now. “If you are looking to create a virtual set or studio, you will need a green or blue screen and a camera capable of delivering a video signal over SDI,” he explains. “To LIVE PRODUCTION Marcus Blom Brodersen says anyone be able to have a dynamic camera for mixed reality, including zoom and focus shifts, you need a camera-tracking system. These come with different features and price points, depending on the type of production you are doing. In the last few months, several high-end remote PTZ cameras have been launched in the market that deliver both video feed and camera tracking in one package,
lowering the threshold for certain types of productions.” For recorded and live experiences, tracking systems from Mo-Sys (VP plug- ins and StarTracker Studio) and Ncam Technologies (Ncam Reality and Ncam AR Suite) plug straight into the Unreal Engine to drive real-time rendered content. The powerful Live Link feature in Unreal Engine allows it to consume animation data from external sources. As well as being used to capturing facial animation at low cost via phone cameras, this can enable real-time performance in a simulated environment, or the complete replacement of the performer with a digital double. The Future Group’s own commercial application, Pixotope, is built for on-air use and live events, enabling rapid design and deployment of virtual, augmented or mixed-reality content. It uses Unreal Engine to produce photorealistic rendering in real time, along with the ability to make last-minute changes while in live mode. “In addition to all the broadcast features that are not part of a game engine:
