Constructor & Destructor Documentation

makVrv::DtTacticalSmokeEmitter::DtTacticalSmokeEmitter

(

)

Default CTOR.

makVrv::DtTacticalSmokeEmitter::DtTacticalSmokeEmitter	(	const DtTacticalSmokeEmitter &	copy,
		const osg::CopyOp &	copyop = osg::CopyOp::SHALLOW_COPY
	)

Copy CTOR.

virtual makVrv::DtTacticalSmokeEmitter::~DtTacticalSmokeEmitter ( )

inlineprotectedvirtual

Protected virtual destructor.

Member Function Documentation

makVrv::DtTacticalSmokeEmitter::META_Object	(	osgParticle	,
		DtTacticalSmokeEmitter
	)

void makVrv::DtTacticalSmokeEmitter::setPosition	(	int	puffIndex,
		const osg::Vec3d &	pos
	)

Set an initial position for a puff of particles.

Parameters

[in]	puffIndex	is the index of the puff position.
[in]	pos	is the puff position for new particles.

void makVrv::DtTacticalSmokeEmitter::setDensity	(	int	puffIndex,
		float	dens
	)

Set an initial density for a puff of particles.

Parameters

[in]	puffIndex	is the index of the puff density.
[in]	dens	is the puff density (alpha) for new particles.

void makVrv::DtTacticalSmokeEmitter::setOneSigma	(	int	puffIndex,
		const osg::Vec3 &	sigmas
	)

Set a sigma-distance for a puff of particles.

Parameters

[in]	puffIndex	is the index of the puff sigma-distances.
[in]	sigmas	is the puff sigma-distances for new particles.

void makVrv::DtTacticalSmokeEmitter::setIntensityRange	(	float	mn,
		float	mx
	)

Set the total number of particles per second for all puffs.

This value is divided by the number of puffs and set for each puff, so a value of sixty for six puffs means ten particles per puff.

Parameters

[in]	mn	is the minimum number to emit (must be greater than zero).
[in]	mx	is the maximum to emit (must be greater or equal to minimum).

void makVrv::DtTacticalSmokeEmitter::setParticleSizeRange	(	float	isz,
		float	fsz
	)

Set the uniform size for all particles in all puffs.

Parameters

[in]	isz	is the initial size of each particle (must be greater than zero).
[in]	fsz	is the final size of each particle (must be greater than zero).

void makVrv::DtTacticalSmokeEmitter::setParticleColorRange	(	const osg::Vec4 &	icl,
		const osg::Vec4 &	fcl
	)

Set the particle color range.

The particles will each change color over their lifetime from an initial color to a final color.

Parameters

[in]	icl	is the initial color.
[in]	fcl	is the final color.

void makVrv::DtTacticalSmokeEmitter::setParticleAlphaMultiplier

(

float

alpha

)

Set the particle initial alpha multiplier.

This value is multiplied by the density to create an initial alpha value for each particle. Values should be normalized from zero to one. Invalid values are clamped.

Parameters

[in]

alpha

is the multiplier to use.

virtual void makVrv::DtTacticalSmokeEmitter::emitParticles ( double  dt )

protectedvirtual

Emit particles for each of the stored particle types.

Parameters

[in]

dt

is the delta-time for this call.

Note

Do not call this function directly. This function is automatically called during updates.

Reimplemented from makVrv::DtImprovedModularEmitter.

DtTacticalSmokeEmitter& makVrv::DtTacticalSmokeEmitter::operator= ( const DtTacticalSmokeEmitter &  )

inlineprotected

Protected copy operator.

PuffData& makVrv::DtTacticalSmokeEmitter::puffData ( int  puffIndex )

private

Get a puff.

Parameters

[in]

puffIndex

is the index of the puff.

Returns

The puff-data at the given index.

Note

If puffIndex is not found, a new puff-data object is created at that index and then returned.
