Member Function Documentation

addTriangle()

void igor::iParticleEmitter::addTriangle

(

const iEmitterTriangle &

triangle

)

adds triangle to mesh emitter

Parameters

triangle

the triangle to add

calcRandomStart()

void igor::iParticleEmitter::calcRandomStart	(	iaVector3d &	position,
		iaVector3d &	velocity
	)

calculates a random start position and velocity from emitter

Parameters

[out]	position	random position on emitter in world coordinates
[out]	velocity	velocity depending on position

calcRandomStartFromCircle()

void igor::iParticleEmitter::clearTriangles

(

)

removes all emitter triangles from mesh

getSize()

float32 igor::iParticleEmitter::getSize

(

)

const

Returns

size of emitter

getType()

iEmitterType igor::iParticleEmitter::getType

(

)

const

Returns

type of emitter

getWorldMatrix()

const iaMatrixd & igor::iParticleEmitter::getWorldMatrix

(

)

const

Returns

world matrix of emitter

setSize()

void igor::iParticleEmitter::setSize

(

float32

size

)

sets size of emitter

how it's interpreted depends on type of emitter Mesh -> none Point -> none Disc -> radius Circle -> radius Sphere -> radius Square -> half edge length Cube -> half edge length

Parameters

size	size of emitter

setType()

void igor::iParticleEmitter::setType

(

iEmitterType

emitterType

)

sets type of emitter

Parameters

emitterType

emitter type

setWorldMatrix()

void igor::iParticleEmitter::setWorldMatrix

(

const iaMatrixd &

matrix

)

sets world matrix of emitter

Parameters

matrix

the matrix to be set
