Function Documentation

get_pose()

static void xrt::auxiliary::tracking::psvr::get_pose ( TrackerPSVR &  t, timepoint_ns  when_ns, struct xrt_space_relation *  out_relation  )

static

Todo:

assuming that orientation is actually currently tracked.

sample_line()

static void xrt::auxiliary::tracking::psvr::sample_line ( cv::Mat &  src, const cv::Point2i &  start, const cv::Point2i &  end, int *  inside_length  )

static

Todo:

: we are counting pixels rather than measuring length - bresenhams may introduce some inaccuracy here.
