Function Documentation

svr_hmd_create()

struct xrt_device * svr_hmd_create

(

struct svr_two_displays_distortion *

distortion

)

Todo:

these should be true for the final product iirc but possibly not for the demo unit

svr_hmd_get_view_poses()

static xrt_result_t svr_hmd_get_view_poses ( struct xrt_device *  xdev, const struct xrt_vec3 *  default_eye_relation, int64_t  at_timestamp_ns, enum xrt_view_type  view_type, uint32_t  view_count, struct xrt_space_relation *  out_head_relation, struct xrt_fov *  out_fovs, struct xrt_pose *  out_poses  )

static

Todo:

: default_eye_relation inherits from the env var OXR_DEBUG_IPD_MM / oxr_session.c

Todo:

you may need to invert this - I can't test locally

svr_mesh_calc()

static xrt_result_t svr_mesh_calc ( struct xrt_device *  xdev, uint32_t  view, float  u, float  v, struct xrt_uv_triplet *  result  )

static

Todo:

: remove hard-coding and move to u_distortion_mesh
