Detailed Description

Class containing all parts of a system for a single type of particle.

This class encompasses all the necessary parts to create a particle system which emits a single type of particle. In this particle system each particle changes over its lifespan according to a Gaussian interpolation. The changes could be transitioning from one size to another, one color to another or one alpha value to another.

Constructor & Destructor Documentation

GaussianParticles::GaussianParticles	(	double	theta,
		double	phi,
		double	sigma = `1.0`,
		double	life = `4.0`,
		double	height = `1.0`
	)

Initialize CTOR The entire particle system is created at construction time.

Parameters

[in]	theta	is an angle which the particles will be streaming from.
[in]	phi	is an angle which the particles will be streaming from.
[in]	sigma	is the sigma value of the Gaussian curve.
[in]	life	is a value to scale the percentage of life each frame.
[in]	height	is a value to scale the final interpreted value.

Member Function Documentation

osg::PositionAttitudeTransform* GaussianParticles::positionAttitudeTransform ( ) const

inline

Accessor to the transform for positioning the emitter.

References myPat.

osgParticle::Particle* GaussianParticles::particle ( ) const

inline

Accessor to the particle template.

Note: Changes to the particle will only take effect when it is set/reset as the template to the osgParticle::ParticleSystem.

References myParticle.

osgParticle::ParticleSystem* GaussianParticles::particleSystem ( ) const

inline

Accessor to the particle system.

Note: The particle system holds a particle as a template and assigns the texture to be used on the particle.

References myParticleSystem.

osgParticle::ParticleSystemUpdater* GaussianParticles::particleSystemUpdater ( ) const

inline

Accessor to the updater.

Note: The updater holds a set of particles and managers their creation, update, rendering and destruction.

References myParticleSystemUpdater.

osgParticle::ModularEmitter* GaussianParticles::modularEmitter ( ) const

inline

Accessor to the emitter.

Note: The emitter provides a single mechanism for controlling many of the elements of the particle system. ( Contains the counter, placer, and shooter. )

References myModularEmitter.

osgParticle::RandomRateCounter* GaussianParticles::randomRateCounter ( ) const

inline

Accessor to the counter.

Note: The counter controls how many particles should create each frame.

References myRandomRateCounter.

osgParticle::PointPlacer* GaussianParticles::pointPlacer ( ) const

inline

Accessor to the placer.

Note: The placer sets the initial position of each particle.

References myPointPlacer.

osgParticle::RadialShooter* GaussianParticles::radialShooter ( ) const

inline

Accessor to the shooter.

Note: The shooter assigns the initial velocity of each particle.

References myRadialShooter.

osgParticle::Program* GaussianParticles::program ( ) const

inline

Accessor to the particle program.

Note: The Program can control the position of individual particles during its lifespan. ( By default not being used in this exercise, but is include for users to experiment with. )
