Detailed Description

template<class Derived>
class pinocchio::ForceBase< Derived >

Base interface for forces representation.

The Class implements all

This class hierarchy represents a spatial force, e.g. a spatial impulse or force associated to a body. The spatial force is the mathematical representation of \( se^{*}(3) \), the dual of \( se(3) \).
