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 void svr_hmd_get_view_poses ( struct xrt_device *  xdev, const struct xrt_vec3 *  default_eye_relation, uint64_t  at_timestamp_ns, 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()

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

Todo:

: remove hard-coding and move to u_distortion_mesh
