Manifold distance
WebManifold distance is the distance from a reference point p to the transformation manifold of s . The tangent distance is the distance from p to the tangent space of the manifold … WebIn mathematics, an isometry (or congruence, or congruent transformation) is a distance -preserving transformation between metric spaces, usually assumed to be bijective. [a] The word isometry is derived from the Ancient Greek: ἴσος isos meaning "equal", and μέτρον metron meaning "measure".
