Cloudgate Studios today rolled the Virtual Self update for Island 359, which brings full-body avatars to the hit VR dinosaur hunting game. Now, spectators can watch you stomp on critters in virtual reality.
The idea of using your feet in Island 359 isn?t new. Cloudgate Studios started working on its full-body awareness system in January (before it even had Vive Trackers to work with), and the company first showed the system to members of the press at GDC in February.
The early implementation of full-body tracking required three Vive Trackers: one for your hips, and two for your feet, and it enabled you to see your legs and body when you looked down at yourself in the game. It also enabled you to kick and stomp on the small chicken-sized dinos that chomp at your shins. The production-ready build is a bit more sophisticated than the version that Cloudgate showed us at GDC. It no longer requires three Vive Trackers, and kicking dinosaurs isn?t the only benefit.
Island 359?s Virtual Self feature supports four different tracking configurations that offer varying levels of body tracking precision. You can use one Vive Tracker to add hip tracking, which enables you to twist your torso and bend your body and Cloudgate would then estimate your foot position. With two Vive Trackers, you can strap them to your feet, which enables you to kick and stomp in the game. This method forgoes the hip tracking, which means you can?t twist your torso independent of your head and feet. With three Vive Trackers, you can have it all with no compromise.
