This model is best viewed by selecting the first person mode in navigation setting and slow speed (eg 0 or 1) and navigating at the neighborhood of the series of small gray cones. It is computed from a video pair taken by a helmet-held 360 camera (Gopro Max) and by kayaking during 30 minutes in the canyon of the Verdon (France). The cones indicate locations of the camera.

All the calculations are based on my publications (with slight modifications for this special case including a river), that are available on http://maxime.lhuillier.free.fr
