Functions
Eigen::Vector3d	reusex::geometry::pixel_to_bearing (const cv::Size &equirect, double u, double v)
	Equirect pixel (u,v) -> unit bearing in the panorama frame.
Eigen::Vector2d	reusex::geometry::bearing_to_pixel (const cv::Size &equirect, const Eigen::Vector3d &bearing)
	Unit bearing (need not be normalised) in panorama frame -> equirect pixel (u,v).
PerspectiveView	reusex::geometry::extract_perspective (const cv::Mat &equirect, double yaw_deg, double pitch_deg, double fov_deg, int out_w, int out_h, int interp=1)
	Render a virtual pinhole view centred at (yaw,pitch) with the given horizontal FOV.
PerspectiveView	reusex::geometry::extract_perspective (const cv::Mat &equirect, const Eigen::Matrix3d &R_pano_from_view, const Eigen::Matrix3d &K, int out_w, int out_h, int interp=1)
	Render a virtual pinhole view with an explicit view->panorama rotation and intrinsics.
std::vector< PerspectiveView >	reusex::geometry::cube_faces (const cv::Mat &equirect, int face_size, int interp=1)
	Tile the whole sphere as the six faces of a cube (90 deg FOV each).
std::vector< PerspectiveView >	reusex::geometry::overlapping_views (const cv::Mat &equirect, int n_yaw, double fov_deg, int tile, int interp=1)
	Tile the sphere as n_yaw evenly spaced views around the equator plus one up and one down view, each with fov_deg horizontal FOV and tile pixels square.
cv::Mat	reusex::geometry::stitch_labels_to_equirect (const cv::Size &out, const std::vector< PerspectiveView > &views, const std::vector< cv::Mat > &tile_labels)
	Stitch per-tile label maps (CV_32S, -1 = background) back into a single equirect label map of size out.
