Detailed Description

The U4DParticlePhysics class is in charge of simulating gravity forces on 3D particles.

Member Function Documentation

evaluateLinearAspect()

void U4DEngine::U4DParticlePhysics::evaluateLinearAspect	(	U4DParticle *	uModel,
		U4DVector3n &	uLinearAcceleration,
		float	dt,
		U4DVector3n &	uVnew,
		U4DVector3n &	uSnew
	)

evaluates the final velocity and position of the 3D particle. Note, only linear velocity is computed.

Parameters

uModel	pointer to the 3D particle
uLinearAcceleration	linear acceleration
dt	time-step
uVnew	reference to new velocity
uSnew	reference to new positon

integrate()

void U4DEngine::U4DParticlePhysics::integrate	(	U4DParticle *	uParticle,
		float	dt
	)

Integrates the equation of motion.

Computes the final velocity and position for the 3D particle. Note, only linear velocity is computed.

Parameters

uParticle	pointer to 3D particle
dt	time-step

updateForce()

void U4DEngine::U4DParticlePhysics::updateForce	(	U4DVector3n	uParticleSystemPosition,
		U4DParticle *	uParticle,
		float	dt
	)

updates the forces affecting the 3D particle.

the only forces affecting a 3D particle is gravitational force

Parameters

uParticleSystemPosition	particle system position
uParticle	pointer to particle
dt	time-step
