Member Enumeration Documentation

enum gtsam::Rot3::CoordinatesMode

The method retract() is used to map from the tangent space back to the manifold. Its inverse, is localCoordinates(). For Lie groups, an obvious retraction is the exponential map, but this can be expensive to compute. The following Enum is used to indicate which method should be used. The default is determined by ROT3_DEFAULT_COORDINATES_MODE, which may be set at compile time, and itself defaults to Rot3::CAYLEY, or if GTSAM_USE_QUATERNIONS is defined, to Rot3::EXPMAP.

Enumerator
EXPMAP 

Use the Lie group exponential map to retract.

CAYLEY 

Retract and localCoordinates using the Cayley transform.

Implementation from here: https://stackoverflow.com/a/23082112/1236990
