Detailed Description

template<class T>
class rw::trajectory::Blend< T >

Interface for blending.

A Blend describes a way to blend between to consecutive interpolators. If we let \( t_1\) be the time switching from one interpolator to the next, then the blend control the path in the interval \( [t_1-\tau_1;t_1+\tau_2]\).

See the specific implementations for at description of which template arguments that are valid.
