Member Function Documentation

virtual void makVrv::DtTacticalSmokeModelInstance::setBasePosition ( const DtVector & v )

virtual

Set base position for particles.

Particle positions will be stored at an offset from this position. After the first time this function is called, it is a no-op.

virtual bool makVrv::DtTacticalSmokeModelInstance::realize ( DtModelDefinition & definition )

virtual

Attempt to realize the instance of this model from a definition.

Parameters

[in] definition is the model definition.

Return values

true	if the instance was realized.
false	otherwise.

Reimplemented from makVrv::DtModelInstance.

virtual void makVrv::DtTacticalSmokeModelInstance::setTexture ( const std::string & txt )

virtual

Set the texture for all particles of this puff.

Parameters

[in] txt is the texture filename.

virtual void makVrv::DtTacticalSmokeModelInstance::setIntensity ( const osg::Vec2 & range )

virtual

Set the number of particles to emit each frame.

These values are spread across all puffs to create a random number of total particles to generate each second.

Parameters

[in] range is the min/max range multipliers, default (6, 12).

virtual void makVrv::DtTacticalSmokeModelInstance::setSizes ( const osg::Vec2 & range )

virtual

Set the initial and final sizes of particles.

These values allow particles to grow or shrink over their lifetime.

Parameters

[in] range is the start/end sizes, default (1, 1).

virtual void makVrv::DtTacticalSmokeModelInstance::setRotations ( const osg::Vec2 & range )

virtual

Set the range of values for angular-velocity of particles.

These values allow particles to rotate continuously over their lifetime. The angular-velocity should be specified in degrees.

Parameters

[in] range is the min/max angular-velocity, default (-10, 10).

virtual void makVrv::DtTacticalSmokeModelInstance::setColors	(	const osg::Vec4 &	ic,
		const osg::Vec4 &	fc
	)

virtual

Set the initial and final colors of particles.

These values allow particles to change colors over their lifetime.

Parameters

[in]	ic	is the initial color, default (1.0, 1.0, 1.0, 1.0).
[in]	fc	is the final color, default (1.0, 1.0, 1.0, 1.0).

virtual void makVrv::DtTacticalSmokeModelInstance::setAlphaMultiplier ( double alpha )

virtual

Set an initial alpha value multiplier for particles.

This is multiplied to starting alpha value of the particles, the ending value is always zero. The alpha value should be a normalized value from zero to one. Invalid values are clamped.

Parameters

[in] alpha is the starting alpha value, default 1.0.

virtual void makVrv::DtTacticalSmokeModelInstance::setSpeed ( double speed )

virtual

Set a constant speed of the particles in meters per second.

Setting this value fixes a constant speed of the particle while forcing each particle to have a variable lifetime.

Parameters

[in] speed is the constant speed of particles, default 0.25.

See Also: setLifetime(double).

virtual void makVrv::DtTacticalSmokeModelInstance::setLifetime ( double life )

virtual

Set a constant lifetime of the particles in seconds.

Setting this value fixes a constant lifetime of the particle while forcing each particle to have a variable speed.

	)

virtual

Set the one-sigma distance per orthogonal direction of a smoke-puff of particles.

Parameters

[in]	puffIndex	is the id of the the particle effect.
[in]	sigma	is the distance in each direction where the probability of particle distribution within that distance is one-sigma (68.3%) from the emitting position.

		double	density
	)

virtual

Set density of a smoke-puff of particles.

Parameters

[in]	puffIndex	is the id of the the particle effect.
