VR developers can now buy Vive Trackers for $99 on Vive.com. The puck-like hardware enables real world objects to be brought into the virtual world.
To help developers incorporate the technology into their software, Vive has today released an open source implementation of full body tracking using three Vive Trackers. You can download the code base from GitHub now.
There is also a dedicated community space for devs and Vive experts to ask questions and solve VR development problems.
