Constructor & Destructor Documentation

VolumeGridEmitter2()

CubbyFlow::VolumeGridEmitter2::VolumeGridEmitter2 ( const ImplicitSurface2Ptr &  sourceRegion, bool  isOneShot = true  )

explicit

Constructs an emitter with a source and is-one-shot flag.

~VolumeGridEmitter2()

virtual CubbyFlow::VolumeGridEmitter2::~VolumeGridEmitter2 ( )

virtual

Destructor.

Member Function Documentation

AddSignedDistanceTarget()

void CubbyFlow::VolumeGridEmitter2::AddSignedDistanceTarget

(

const ScalarGrid2Ptr &

scalarGridTarget

)

Adds signed-distance target to the scalar grid.

AddStepFunctionTarget()

void CubbyFlow::VolumeGridEmitter2::AddStepFunctionTarget	(	const ScalarGrid2Ptr &	scalarGridTarget,
		double	minValue,
		double	maxValue
	)

Adds step function target to the scalar grid.

Parameters

[in]	scalarGridTarget	The scalar grid target.
[in]	minValue	The minimum value of the step function.
[in]	maxValue	The maximum value of the step function.

AddTarget() [1/2]

void CubbyFlow::VolumeGridEmitter2::AddTarget	(	const ScalarGrid2Ptr &	scalarGridTarget,
		const ScalarMapper &	customMapper
	)

Adds a scalar grid target.

This function adds a custom target to the emitter. The first parameter defines which grid should it write to. The second parameter, customMapper, defines how to map signed-distance field from the volume geometry and location of the point to the final scalar value that is going to be written to the target grid. The third parameter defines how to blend the old value from the target grid and the new value from the mapper function.

Parameters

[in]	scalarGridTarget	The scalar grid target
[in]	customMapper	The custom mapper.

AddTarget() [2/2]

void CubbyFlow::VolumeGridEmitter2::AddTarget	(	const VectorGrid2Ptr &	vectorGridTarget,
		const VectorMapper &	customMapper
	)

Adds a vector grid target.

This function adds a custom target to the emitter. The first parameter defines which grid should it write to. The second parameter, customMapper, defines how to map signed-distance field from the volume geometry and location of the point to the final vector value that is going to be written to the target grid. The third parameter defines how to blend the old value from the target grid and the new value from the mapper function.

Parameters

[in]	vectorGridTarget	The vector grid target
[in]	customMapper	The custom mapper.

GetBuilder()

static Builder CubbyFlow::VolumeGridEmitter2::GetBuilder ( )

static

Returns builder fox VolumeGridEmitter2.

GetIsOneShot()

bool CubbyFlow::VolumeGridEmitter2::GetIsOneShot

(

)

const

Returns true if this emits only once.

GetSourceRegion()

const ImplicitSurface2Ptr& CubbyFlow::VolumeGridEmitter2::GetSourceRegion

(

)

const

Returns implicit surface which defines the source region.
