Detailed Description

template<typename versatile_types>
class OpenTissue::versatile::Simulator< versatile_types >

Versatile Method.

Some observations:

Good stability <- small time steps, small geometries (re-scale world to unity), keep k_D, k_A, k_V below 100 or so.

void OpenTissue::versatile::Simulator< versatile_types >::run	(	real_type const &	dT,
		real_type const &	fraction
	)			[inline]

Run Simulation. Remeber to compute external forces prior to invoking this method.

Parameters:

	dT	The frame time.
	fraction	Error reduction parameter, indicates the fraction that penetrations should be reduced too within time dT. Don't be too overeager, value of 0.05 (5%) seems to do a good job.

void OpenTissue::versatile::Simulator< versatile_types >::run	(	real_type const &	dT,
		real_type const &	fraction,
		real_type const &	dt
	)			[inline, protected]

Time-Step method.

Parameters:

	dT	Frame time-step.
	fraction	Penetration reduction parameter.
	dt	The time-step time. Observe that an explicit integration method (Verlet) is being used. Your time-step should be order of ms (milliseconds) otherwise the simulation becomes unstable.
