Did you see that OptiTrack has a new Unity Plugin?

OptiTrack have just announced their Unity Plugin has been updated.

The OptiTrack Unity3D Plugin allows real-time streaming of live or recorded motion tracking data from Motive into Unity. Kinetic data from both rigid body and skeleton tracking can be streamed via the plugin, and received data can be used for animating objects and characters within a scene in Unity. The plugin contents are distributed in a unitypackage format and you can simply load this file into Unity projects. Once imported, the included C# scripts can be attached to Unity objects for instantiating a client and receiving the tracking data.

OptiTrack Introduces Active VR Tracking at GDC 2017

OptiTrack delivers the best active tracking solution ever built, with the lowest deployment cost for theme park scaled VR experiences

OptiTrack today introduced OptiTrack Active, a solution tailored specifically for out-of-home, theme park scaled virtual reality (VR) experiences. This advancement enables greatly simplified manufacturing and deployment efforts for large-scale, multi-user VR experiences. OptiTrack Active will be showcased using Oculus HMDs, Striker VR weapons, and MSI VR One Backpack PCs in the OptiTrack booth (#2002, South Hall) at the 2017 Game Developers Conference, held at the Moscone Center in San Francisco March 1-3.

At the core of OptiTrack Active are infra-red LEDs synchronized with OptiTrack’s low latency, high frame rate, Slim 13E cameras, thereby delivering real time marker identification as well as positioning. This differs from OptiTrack’s passive solution, which requires that reflective markers be configured in unique patterns for each tracked object. This can add a great deal of complexity for high volume manufacturing and large scale deployments of HMDs or weapons. With OptiTrack Active over 100 objects can be tracked simultaneously over areas greater than 100’x100’ (30mx30m), while maintaining world leading precision and low latency.

“We heard the market loud and clear – the leaders in the out-of-home VR space wanted all the tracking performance that OptiTrack systems deliver, but with a way that allows them to build and deploy 500 identical HMDs, not 500 slightly different configurations. The result is the best active tracking system ever built and the lowest cost to rollout to dozens of sites” said Brian Nilles, OptiTrack’s Chief Strategy Officer. “The Slim13E camera, designed specifically for OptiTrack Active, delivers 240fps freeze frame capture and is also 40% lower cost than its passive tracking equivalent. We delivered in every category, one sku manufacturing, dramatically lower overall system cost – and we even improved the tracking quality.”
