Detailed Description

Linear interpolation between two configurations

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.
