Detailed Description

2-D volumetric particle emitter.

This class emits particles from volumetric geometry.

Constructor & Destructor Documentation

VolumeParticleEmitter2()

CubbyFlow::VolumeParticleEmitter2::VolumeParticleEmitter2	(	const ImplicitSurface2Ptr &	implicitSurface,
		const BoundingBox2D &	bounds,
		double	spacing,
		const Vector2D &	initialVel = Vector2D(),
		size_t	maxNumberOfParticles = std::numeric_limits< size_t >::max(),
		double	jitter = 0.0,
		bool	isOneShot = true,
		bool	allowOverlapping = false,
		uint32_t	seed = 0
	)

Constructs an emitter that spawns particles from given implicit surface which defines the volumetric geometry. Provided bounding box limits the particle generation region.

Parameters

[in]	implicitSurface	The implicit surface.
[in]	bounds	The max region.
[in]	spacing	The spacing between particles.
[in]	initialVel	The initial velocity.
[in]	maxNumberOfParticles	The max number of particles to be emitted.
[in]	jitter	The jitter amount between 0 and 1.
[in]	isOneShot	Set true if particles are emitted just once.
[in]	allowOverlapping	True if particles can be overlapped.
[in]	seed	The random seed.

Member Function Documentation

GetAllowOverlapping()

bool CubbyFlow::VolumeParticleEmitter2::GetAllowOverlapping

(

)

const

Returns true if particles can be overlapped.

GetBuilder()

static Builder CubbyFlow::VolumeParticleEmitter2::GetBuilder ( )

static

Returns builder fox VolumeParticleEmitter2.

GetInitialVelocity()

Vector2D CubbyFlow::VolumeParticleEmitter2::GetInitialVelocity

(

)

const

Sets the initial velocity of the particles.

GetIsOneShot()

bool CubbyFlow::VolumeParticleEmitter2::GetIsOneShot

(

)

const

Returns true if particles should be emitted just once.

GetJitter()

double CubbyFlow::VolumeParticleEmitter2::GetJitter

(

)

const

Returns jitter amount.

GetMaxNumberOfParticles()

size_t CubbyFlow::VolumeParticleEmitter2::GetMaxNumberOfParticles

(

)

const

Returns max number of particles to be emitted.

GetSpacing()

double CubbyFlow::VolumeParticleEmitter2::GetSpacing

(

)

const

Returns the spacing between particles.

SetAllowOverlapping()

void CubbyFlow::VolumeParticleEmitter2::SetAllowOverlapping

(

bool

newValue

)

Sets the flag to true if particles can overlap each other.

If true is set, the emitter will generate particles even if the new particles can find existing nearby particles within the particle spacing.

Parameters

[in]

newValue

True if particles can be overlapped.

SetInitialVelocity()

void CubbyFlow::VolumeParticleEmitter2::SetInitialVelocity

(

const Vector2D &

newInitialVel

)

Returns the initial velocity of the particles.

SetIsOneShot()

void CubbyFlow::VolumeParticleEmitter2::SetIsOneShot

(

bool

newValue

)

Sets the flag to true if particles are emitted just once.

If true is set, the emitter will generate particles only once even after multiple emit calls. If false, it will keep generating particles from the volumetric geometry. Default value is true.

Parameters

[in]

newValue

True if particles should be emitted just once.

SetJitter()

void CubbyFlow::VolumeParticleEmitter2::SetJitter

(

double

newJitter

)

Sets jitter amount between 0 and 1.

SetMaxNumberOfParticles()

void CubbyFlow::VolumeParticleEmitter2::SetMaxNumberOfParticles

(

size_t

newMaxNumberOfParticles

)

Sets the max number of particles to be emitted.

SetPointGenerator()

void CubbyFlow::VolumeParticleEmitter2::SetPointGenerator

(

const PointGenerator2Ptr &

newPointsGen

)

Sets the point generator.

This function sets the point generator that defines the pattern of the point distribution within the volume.

Parameters

[in]

newPointsGen

The new points generator.

SetSpacing()

void CubbyFlow::VolumeParticleEmitter2::SetSpacing

(

double

newSpacing

)

Sets the spacing between particles.
