Here's example from Flightgear protocol:\r\nhttps://github.com/opentrack/opentrack/blob/0bc78d53028f5ac68b9ab454347b8ad453988c08/proto-flightgear/ftnoir_protocol_fg.cpp#L25\r\n\r\nOr some sort of generic (I guess) UDP protocol:\r\nhttps://github.com/opentrack/opentrack/blob/0bc78d53028f5ac68b9ab454347b8ad453988c08/proto-udp/ftnoir_protocol_ftn.cpp#L26\r\n\r\nSo, simply six doubles...\r\n\r\nI believe these values should be added on top of these changed by mouse/numpad, so that you can switch to rear camera and then take a look around freely using head tracker."}}
