Math::Extrapolator< TYPE > Class Template Reference

#include <extrapolator.h>

Detailed Description

template<class TYPE>
class Math::Extrapolator< TYPE >

Extrapolator maintains state about updates for remote entities, and will generate smooth guesses about where those entities will be based on previously received data.

This implementation is based on http://www.mindcontrol.org/~hplus/epic/ Its adapted for use with point and vector class.

bool	AddSample (Timing::Time packetTime, Timing::Time curTime, const TYPE &pos)
	add sample without velocity, velocity is compute from positions
bool	AddSample (Timing::Time packetTime, Timing::Time curTime, const TYPE &pos, const TYPE &vel)
	add sample with given velocity
void	Reset (Timing::Time packetTime, Timing::Time curTime, const TYPE &pos)
	Re-set the Extrapolator's idea of time, velocity and position.
void	Reset (Timing::Time packetTime, Timing::Time curTime, const TYPE &pos, const TYPE &vel)
	Re-set the Extrapolator's idea of time, velocity and position.
bool	ReadValue (Timing::Time forTime, TYPE &oPos) const
bool	ReadValue (Timing::Time forTime, TYPE &oPos, TYPE &oVel) const
Timing::Time	EstimateLatency () const
	Returns: the current estimation of latency between the sender and this interpolator.
Timing::Time	EstimateUpdateTime () const
	Returns: the current estimation of frequency of updates that the sender will send.

template<class TYPE>

bool Math::Extrapolator< TYPE >::ReadValue	(	Timing::Time	forTime,
		TYPE &	oPos
	)			const

Return an estimate of the interpolated position at a given global time (which typically will be greater than the curTime passed into AddSample()).
