flow(
objects
, [divisions=[uint, uint, uint]], [localCompute=boolean], [localDivisions=[uint, uint, uint]], [objectCentered=boolean])
Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.
flow is undoable, queryable, and editable.
The flow command creates a deformation lattice to `bend' the object
that is animated along a curve of a motion path animation.
The motion path animation has to have the follow option set to be on.

Properties |
divisions(dv)
|
[uint, uint, uint]
|
|
|
This flag specifies the number of lattice slices
in x,y,z.
The default values are 2 5 2.
When queried, it returns the TuInt32 TuInt32 TuInt32
|
|
localCompute(lc)
|
boolean
|
|
|
This flag specifies whether or not to have local
control over the object deformation.
Default value:
is on when the lattice is around the curve, and
is off when the lattice is around the object.
When queried, it returns a boolean
|
|
localDivisions(ld)
|
[uint, uint, uint]
|
|
|
This flag specifies the extent of the region of effect.
Default values are 2 2 2.
When queried, it returns the TuInt32 TuInt32 TuInt32
|
|
objectCentered(oc)
|
boolean
|
|
|
This flag specifies whether to create the lattice around
the selected object at its center, or to create the lattice
around the curve.
Default value is true.
When queried, it returns a boolean
|
