Lunar Orientation Visualizer
An interactive exploration of observer-centered rotations
Explore lunar libration with quaternion, matrix,
Rodrigues and axis-angle representations!
Left-click and drag to rotate the Moon (change libration state)
Right-click and drag to fly around the Moon (observer is stationary)
Dashed Rings - Moon's limb as seen at ∞ (gray) / slider dist (black)
RGB markers/arrows - Basis vectors (North, 0° [Observer], 90° East)
Sub-observer: —
Point on the Moon directly facing the observer.
(Green dot)
Sub-camera: —
Point on the Moon currently centered in the view.
