Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.
fluidEmitter is undoable, queryable, and editable.
Creates an emitter object. If object names are provided or if objects are
selected, applies the emitter to the named/selected object(s)in the
scene. Fluid will then be emitted from each. If no objects are
named or selected, or if the -pos option is specified, creates a
positional emitter.
If an emitter was created, the command returns the name of the object
owning the emitter, and the name of emitter shape. If an emitter was
queried, the command returns the results of the query.
In query mode, return type is based on queried flag.

Properties |
|
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.
|
|
densityEmissionRate(der)
|
float
|
|
|
Rate at which density is emitted.
|
|
fluidDropoff(fdr)
|
float
|
|
|
Fluid Emission Dropoff in volume
|
|
fuelEmissionRate(fer)
|
float
|
|
|
Rate at which is emitted.
|
|
heatEmissionRate(her)
|
float
|
|
|
Rate at which density is emitted.
|
|
maxDistance(mxd)
|
linear
|
|
|
Maximum distance at which emission ends.
|
|
minDistance(mnd)
|
linear
|
|
|
Minimum distance at which emission starts.
|
|
position(pos)
|
[linear, linear, linear]
|
|
|
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.
|
|
torusSectionRadius(tsr)
|
linear
|
|
|
Section radius for a torus volume. Applies only to torus.
Similar to the section radius in the torus modelling primitive.
|
|
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.
|
|
volumeOffset(vof)
|
[linear, linear, linear]
|
|
|
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.
|
|
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."
|
|
volumeSweep(vsw)
|
angle
|
|
|
Volume sweep of the emitter. Applies only to sphere, cone,
cylinder, and torus. Similar effect to the sweep attribute
in modelling.
