-type
(-typ)
| string |   |
|
Type of emitter. The choices are omni | dir | direction | surf |
surface | curve | curv. The default is omni.
The full definition of these types are: omnidirectional point emitter,
directional point emitter, surface emitter, or curve emitter.
|
|
-directionX
(-dx)
| float | |
|
x-component of emission direction.
Used for directional emitters, and for volume emitters with
directionalSpeed.
|
|
-directionY
(-dy)
| float | |
|
y-component of emission direction.
Used for directional emitters, and for volume emitters with
directionalSpeed.
|
|
-directionZ
(-dz)
| float | |
|
z-component of emission direction.
Used for directional emitters, and for volume emitters with
directionalSpeed.
|
|
-minDistance
(-mnd)
| float | |
|
Minimum distance at which emission starts.
|
|
-maxDistance
(-mxd)
| float | |
|
Maximum distance at which emission ends.
|
|
-position
(-pos)
| float float float | |
|
Positional emitter at world space location (x,y,z).
|
|
-rate
(-r)
| float | |
|
Rate at which particles emitted (can be non-integer).
For point emission this is rate per point per unit time.
For surface emission it is rate per square unit of area per unit time.
|
|
-spread
(-sp)
| float | |
|
Random spread (0-1), as a fraction of 90 degrees,
along specified direction. Directional emitters only.
|
|
-speedRandom
(-srn)
| float | |
|
Identifies a range of random variation for the speed of
each generated particle. If set to a non-zero value, speed
becomes the mean value of the generated particles, whose speeds
vary by a random amount up to plus or minus speedRandom/2.
For example, speed 5 and speedRandom 2 will make the speeds
vary between 4 and 6.
|
|
-cycleEmission
(-cye)
| string | |
|
Possible values are "none" and "frame."
Cycling emission restarts the random number stream after
a specified interval. This can either be a number of frames
or a number of emitted particles. In each case the number
is specified by the cycleInterval attribute. Setting cycleEmission to
"frame" and cycleInterval to 1 will then re-start the random stream every
frame. Setting cycleInterval to values greater than 1 can be used
to generate cycles for games work.
|
|
-cycleInterval
(-cyi)
| int | |
|
Specifies the number of frames or particles between restarts of
the random number stream. See cycleEmission. Has no effect if
cycleEmission is set to None.
|
|
-speed
(-spd)
| float | |
|
Speed multiple. Multiplies the velocity of the
emitted particles by this amount. Does not apply to volume
emitters. For that emitter type, use directionalSpeed.
|
|
-normalSpeed
(-nsp)
| float | |
|
Normal speed multiple for point emission. For each emitted
particle, multiplies the component of the velocity normal
to the surface or curve by this amount. Surface and curve
emitters only.
|
|
-tangentSpeed
(-tsp)
| float | |
|
Tangent speed multiple for point emission.
For each emitted particle, multiplies the component of the velocity
tangent to the surface or curve by this amount.
Surface and curve emitters only.
|
|
-volumeShape
(-vsh)
| string | |
|
Volume shape of the emitter. Sets/edits/queries the
field's volume shape attribute. If set to any value other
than "none", determines a 3-D volume within which
particles are generated.
Values are: "cube," "sphere," "cylinder," "cone," "torus."
|
|
-volumeOffset
(-vof)
| float float float | |
|
Volume offset of the emitter. Volume offset translates
the emission volume by the specified amount from the actual
emitter location. This is in the emitter's local space.
|
|
-volumeSweep
(-vsw)
| float | |
|
Volume sweep of the emitter. Applies only to sphere, cone,
cylinder, and torus. Similar effect to the sweep attribute
in modelling.
|
|
-torusSectionRadius
(-tsr)
| float | |
|
Section radius for a torus volume. Applies only to torus.
Similar to the section radius in the torus modelling primitive.
|
|
-awayFromCenter
(-afc)
| float | |
|
Initial velocity multiplier in the direction away from
the center point of a cube or sphere volume emitter. Used only with
the cube and sphere volume emitters.
|
|
-awayFromAxis
(-afx)
| float | |
|
Initial velocity multiplier in the direction away
from the central axis of the volume. See the diagrams
in the documentation. Used only with the cylinder, cone,
and torus volume emitters.
|
|
-aroundAxis
(-arx)
| float | |
|
Initial velocity multiplier in the direction around
the central axis of the volume. See the diagrams
in the documentation. Applies only to volume emitters.
|
|
-alongAxis
(-alx)
| float | |
|
Initial velocity multiplier in the direction along
the central axis of the volume. See the diagrams in
the documentation. Applies only to volume emitters.
|
|
-randomDirection
(-rnd)
| float | |
|
Magnitude of a random component of the speed
from volume emission.
|
|
-directionalSpeed
(-drs)
| float | |
|
For volume emitters only, adds a component of speed in the
direction specified by the directionX, Y, and Z attributes.
Applies only to volume emitters. Does not apply to other types
of emitters.
|
|
-scaleSpeedBySize
(-ssz)
| boolean | |
|
Indicates whether the scale of a volume emitter
affects its velocity.
|
|
-needParentUV
(-nuv)
| boolean | |
|
If aNeedParentUV is true, compute parentUV value from
each triangle or each line segment, then send out to the
target particle object. You also need to add parentU and
parentV attributes to the particle object to store these values.
|
|
-scaleRateByObjectSize
(-sro)
| boolean | |
|
Applies to curve and surface emitters, only.
If true, number of particles is determined by object size
(area or length) times rate value. If false, object size
is ignored and the rate value is used without modification.
The former is the way Maya behaved prior to version 3.0.
