Math::PFeedbackLoop< TYPE > Class Template Reference

#include <pfeedbackloop.h>

Detailed Description

template<class TYPE>
class Math::PFeedbackLoop< TYPE >

A P feedback loop (proportional feedback loop) is a simple object which moves a system's current state towards a goal, using the resulting error (difference between goal and state as feedback on the next run.

If you need to implement motion controllers, camera controllers, etc... then the feedback loop is your friend.

See Game Developer Mag issue June/July 2004.
