Detailed Description

Piecewise linear interpolation between two configurations

This type of path is the return type of PathProjector algorithms.

Degrees of freedom are interpolated depending on the type of joint they parameterize:

linear interpolation for translation joints, bounded rotation joints, and translation part of freeflyer joints,
angular interpolation for unbounded rotation joints,
constant angular velocity for SO(3) part of freeflyer joints.
