HTC Releases Full Body Tracking Code for Use with Vive and Trackers
HTC Vive Senior Engineer James Xiong has provided a Vive IK Demo on GitHub, which includes a reference source code and Unity demo. Using the HTC Vive headset and controllers combined with three Vive Trackers, the program uses hardware tracking and inverse kinematics to pose a virtual model that closely matches the human player.
By tracking a headset and two motion controllers held in the hands, developers are able to achieve a reasonably accurate virtual representation of the upper body. In some VR experiences, the user is able to look down and see a full body avatar, but this is often avoided, as there is too much guesswork involved in animating the lower body.
